Today we talk about the color temperature of LED home furniture lighting equipment, more people still do not grasp

Color temperature is a definition of which? Many people understand that the creamy white, yellowish light, then it is the color of the light is not a random selection, this different color temperature can change the different mentality of people, for example: the northern region of the people subconsciously pick white light lights, and the southern region of the people subconsciously pick white lights mostly; then this is why?

panel light

Because the yellow only belongs to the warm light, while the white light is classified as a cool light, so because the climate and other factors caused by the level of the northern region will subconsciously select the warm complex color light, while the northerners subconsciously select the cool light;

LED home furniture lighting equipment color temperature is a certain temperature “K” to show, to a standard black letter heating, the temperature rises to a certain level when the color gradually from crimson – light red – orange – white – blue, slowly change, a light source and the black letter of the same color, we will be black letter at that time the temperature of a certain light source called the color temperature.

Because the color temperature is actually black body radiation close to the light source light color, the light source light color main performance evaluation value, and is not a precise color comparison, so with the same color temperature value of the 2 light sources, it is likely that there is still a difference in the light color appearance. Color temperature alone can not grasp the ability of the light source to color objects, or how to reproduce the color of objects under the light source. Different light sources natural environment of the relevant color temperature.

Light source color temperature is not the same, the light color is not the same, color temperature in the following 3000k has a warm feeling, to achieve a calm atmosphere; color temperature in the 3000k-5005k for the middle color temperature, there is a painful feeling; color temperature in the 5005k above the cold feeling.

From the spectral chart, we can clearly see that matching color means matching color temperature; then in the testing report of lighting fixtures, we engage in a good batch of lighting fixtures, such as the production and manufacture of 100,000pcs of lighting fixtures, then this time, is able to be a sampling test, in different batches of light sources manufacturing, the color temperature of the finished lighting fixtures is a certain hazard, in other words, we only Need to be in a color temperature of positive and negative 100-200K are counted as all normal categories;

Therefore, after we go to the lighting factory to buy lights, you can test the special color temperature, then a LED furniture lighting equipment, not only by the lighting color temperature decision, but also the key parameters: special effects, indicate, lumen value, light intensity, there is no glare, there is no flash frequency, and its luminous perspective and other such major parameters together decision;

To cite a simple example: it is said that the lighting perspective, flat panel lights (also known as led flat panel lights, there are irradiated and side lighting) are generally used in the key lighting areas, while track spotlights, track spotlights, ceiling lights are auxiliary lighting, suitable for decorative design class, such as fashion stores with more is led track lights;

Influenza season! When this happens, you need to be careful that it is not influenza.

It is important to note that when there are two children in the family and one of them has the flu, the main family member who is relatively immobile should try to take care of the patient and take care of safety precautions; other main family members should try to avoid touching the flu patient, especially children who are not infected with the flu.


In this flu season, how can we detect the flu as soon as possible? What are the symptoms? How to prevent children from getting the flu? How to prevent influenza in daily life? Previously, there are authoritative experts in the family physician online consultation service platform to help me explain this problem in detail.

What is the difference between influenza and viral flu? How to confirm the diagnosis?


How can I tell if I have the flu or a viral cold? What are the significant symptoms of influenza? Dr. Chi Xiaoling, director of the liver disease specialist at Guangdong Hospital of Traditional Chinese Medicine, told us that viral flu is caused by a variety of viral infections and is often released, with a slow onset and significant upper respiratory symptoms and lighter symptoms all over the body. Fever cold alias wind chill, also known as acute sinusitis or respiratory khat, is specific to the throat khat symptoms. Adults are mostly seen caused by rhinovirus, followed by parainfluenza virus infection, respiratory syncytial virus, echovirus infection and coxsackievirus. The onset of the disease is rapid, with a dry throat, itchy or burning sensation in the early stage, and in addition or several hours after the onset of the disease, there may be sneezing, nose blockage, cold water-like runny nose, which thickens after 2 to 3 days. It can be accompanied by sore throat, sometimes because of Eustachian tube inflammation makes English hearing reduced, also can occur tearing, taste bud retardation, breathing difficulty, hoarseness, small amount of dry cough, etc. There is usually no fever or generalized illness, or only a low fever, malaise, mild chills and headache.


The examination thus reveals hematoma, puffiness, and minute muster of the nasal mucosa and slight hematoma of the throat. If there is no disease onset, it is usually cured in 5~7 days. It is relatively difficult to distinguish from mild form of influenza, and accurate identification requires corresponding examination of pathogenic bacteria. The corresponding test for influenza virus infection in general influenza is negative.

Influenza is diagnosed using a hierarchy of criteria for confirmation. The diagnosis can be confirmed during the epidemic and pandemic periods based on clinical manifestations, but the initial release of influenza cases should integrate epidemiological history, clinical symptoms, and laboratory tests to confirm the diagnosis comprehensively.

How to prevent influenza in daily life?

Dr. Liang Donghui, Director of the Department of Acupuncture and Moxibustion of Zhujiang Hospital of Southern Medical University, informed in the online consultation service platform of family physicians that it is important to ensure sufficient sleep, maintain a stable mental substance mentality, consume sufficient fluids and take ingredients with nutritional content, etc. Try to avoid touching flu-like patients.

Pay attention to cleanliness and hygiene, often apply soap and cold water to wash and disinfect hands, especially after a dry cough or snorting. Try to avoid going out especially to venues where groups gather. During the flu epidemic, pregnant women who are expecting should wear a mask when they go out and should minimize the time they stay in crowded places.

Prevent multiple reuse of protective masks. If you have a mask that can be reused multiple times, be sure to sterilize it and air-dry it after application. Cover your mouth and nose with toilet paper when coughing or snorting, and throw the used toilet paper into the trash. Avoid touching your eyes, nose or mouth with your hands as much as possible. Maintain good natural ventilation in your home and workplace.

How to prevent influenza in children?

Relatively speaking, children and teenagers have poor resistance and often come out in public places such as campus and ecological parks, so how can children and teenagers prevent pediatric influenza? Dr. Qiu Meiqing, Director of the Department of Pulmonary Diseases of Guangzhou Hospital of Traditional Chinese Medicine, informs us that there are several levels of prevention of influenza (flu) as follows.

①When there is a flu epidemic, pay attention to prevent taking children to public places, such as theaters, large shopping malls and other areas where groups gather, and if it is difficult to avoid going to public places, you can put a mask on your child. There are certain isolation measures between sick children and children to prevent mutual infection.

②The residence should be disinfected and sterilized, and the vinegar disinfection method can be used. Close the windows and doors, put 2-5ml of vinegar per cubic meter of indoor space, put water 1-2 times, and heat it up until it is vaporized, so as to disinfect and sterilize the house, once a day for several days.

③ Pay attention to the symptoms of cold, whether there is dry cough, whether there is sore throat, whether there is slight increase of basic body temperature, whether there is mucus and runny nose or blocked nose and squirting, etc. Some babies can be accompanied by abdominal pain, diarrhea, and some babies can be caused by high fever and twitching, most of them can be cured within a week, but if the history of the disease changes or intensifies, it is likely to be combined with other diseases.

What kind of microphone should we use in different scenes?

With the popularity of vlogging, many small things in life like to use vlogging to record these scenes on screen. There are many people who buy a lot of filming equipment in order to shoot good vlog videos, but most of them will concentrate on buying lenses and cameras to pursue high quality images, thus ignoring the importance of sound. In fact, sound is also a very important part. For example: I am now recording a Vlog, recorded indoors, then, the directional microphone can get better sound, but to a crowded and noisy place, the directional microphone is not very good at suppressing the noise around, so when I switch to a lavalier microphone, this effect, it can improve a lot.

best wireless lavalier microphone

Today I want to share with you the different kinds of microphones suitable for use in that environment and scenario and why they are used in this way.

Some time ago, I found a lot of different kinds of microphones to test the effect of using in different scenes and environments. The first test was a shotgun microphone. If you ask the editor for a what China’s first on the test gun microphone, the main problem is that the gun microphone to carry more education mass, the use of more people. First of all, the advantage of the gun microphone is that it has a good unidirectional nature. It is well known that sound waves propagate in all directions, and directivity refers to the sensitivity of the microphone to the direction of sound in space. Unidirectionality simply accepts sound from the front only and ignores sound from the side and back.

This is why many vloggers prefer to use directional microphones, like this one, to hang the microphone on the head of the camera, so that the microphone is parallel to the lens, using the characteristics of directional microphones to get the maximum sound of people speaking from the front, and to be able to avoid the noise from the side and the back.

At the same time, directional microphones are also ideal for use as a post-analog radio tool, which can make up for the missing sound in previously recorded videos through post-recording supplements, elevating the video viewing experience to a higher level. Of course, the directionality of directional microphones varies by price. In addition, directional role is not a panacea, want to get better sound through the enterprise, or need to allow the microphone can be the maximum different degrees of proximity to the person, too far away from the effect will be greatly reduced.

Another microphone is the lavalier microphone, lavalier microphone is actually belong to the omnidirectional microphone, due to the lavalier microphone size and performance limitations, can make good use of the advantages of omnidirectional microphone, only collect all the sound near the omnidirectional microphone, the closer the microphone to our mouth, the better the quality of the collected sound, the less background noise. This is why, in general, clip-on microphones sound a little better than directional microphones.

In order to facilitate the shooting, I will also purchase some wireless sound transmission equipment, such as this Wireless Go, through the wireless signal transmission, solve the microphone wire distance limit, but also more beautiful and convenient, it with the lavalier microphone to use the most suitable, ideal for interviews, or at the show.

Finally, to conclude, the gun microphone is very directional, no matter where you point it, you can receive the sound. The sound source is closer to the microphone, so you can get a better reception. The lavalier microphone, omnidirectional, is suitable for recording vocals in a noisy sound environment. With this wireless microphone, you can achieve the effect of a long-distance radio.

Microphone in many problems when we have overlapping scenarios. There are so many microphones that you can’t use all of them at the same time.

If you only want to use one microphone, I suggest you buy a shotgun microphone, which has a wide range of applications and is cost-effective.

The lethal damage of amateurs: just have it (generally don?¡¥t care in regards to the seem excellent from the sound)

When shooting, I?¡¥m most frightened of encountering these kinds of perfunctory words and phrases as ?¡ãjust take the picture?¡À or ?¡ãthe seem might be recorded to it?¡À. Other issues are mainly inquiring a few questions. Although it appears that there’s no trouble with this way, there will be loopholes inside the afterwards modifying system, plus the distinction between skilled and novice can be clearly found.

Normally made use of microphone styles

After we are capturing video clips, the typically made use of microphone kinds typically involve condenser microphones and dynamic microphones. Condenser microphones ship seem into the internal diaphragm and vibrate to bring about the diaphragm to vibrate, triggering the voltage to change after which you can crank out a signal. It has higher sensitivity and is frequently utilized for high-quality recordings, these as guitar playing, complicated environmental seems, and recording inside a studio. Some condenser microphones have to have phantom power to get audio, which is troublesome to implement. A further kind of dynamic microphone is fairly much less expensive than some areas of the worth as it is made up of coils and magnets, contrary to condenser microphones, which can be lighter and fewer sensitive to high frequencies, but the audio it includes is softer and ideal for recording. Vocals and dwell performances, etcetera., from the indoor recording studio, component of the foley workers will even use this kind of microphone for foley work. Our widespread microphone head pointing is usually divided into super cardioid pointing microphone and cardioid pointing microphone.

Can it be safer to obtain a minimal quantity?

Once the quantity reaches pink, distortion will occur, much like if the camera bursts and becomes totally white throughout capturing, there is certainly no solution to help save it. Thus, in order to reduce popping, a number of people just alter the microphone volume to your least, to ensure that irrespective of how loud the audio is, it’s going to not access the warning zone. Even though it may be very safe, it might have an impact on the seem quality. This is another position of information we need to have an understanding of: sounds ground

What exactly is the sounds flooring? It can be background sound, which interprets as “noise floor”. Frequently refers to all interference which includes very little to do along with the presence or absence in the signal during the event, inspection, measurement or recording process. But in industrial sounds or environmental sounds measurement, it refers back to the ambient sounds outside the measured sound resource. One example is, if your sounds measured to the road close to the manufacturing facility is targeted traffic noise, the manufacturing facility sound is definitely the track record sounds. If your objective of measurement is always to measure manufacturing facility noise, visitors noise will become background sounds. From the course of action of sound measurement. Awareness should be paid to the degree of interference from history noise. Therefore if you naively assume which the volume must be decrease when recording, after which you can it will likely be improved to generate it louder whenever you return, then you definately should be mentally prepared for that sounds to be amplified.

Standard Things of the Wi-fi Interaction Process

A typical Wireless Interaction Technique could be divided into a few aspects: the Transmitter, the Channel along with the Receiver. The next graphic reveals the block diagram of wi-fi interaction method.

smart module

The Transmission Path

A standard transmission path of a Wi-fi Communication Method is made up of Encoder, Encryption, Modulation and Multiplexing. The signal from the resource is handed through a Resource Encoder, which converts the signal in to some ideal sort for implementing sign processing techniques.

The redundant facts from sign is eliminated on this procedure as a way to maximise the utilization of assets. This signal is then encrypted employing an Encryption Common to make sure that the sign plus the details is secured and doesn?¡¥t make it possible for any unauthorised access.

Channel Encoding is a strategy which is placed on the signal to scale back the impairments like noise, interference, and so forth. All through this method, a little quantity of redundancy is released towards the signal to make sure that it becomes sturdy in opposition to sounds. Then the sign is modulated working with an appropriate Modulation Technique (like PSK, FSK and QPSK etc.) , to ensure the signal is usually simply transmitted applying antenna.

The modulated sign is then multiplexed with other indicators using distinctive Multiplexing Procedures like Time Division Multiplexing (TDM) or Frequency Division Multiplexing (FDM) to share the valuable bandwidth.

The Channel

The channel in Wi-fi Communication signifies the medium of transmission in the sign i.e. open up area. A wi-fi channel is unpredictable as well as very variable and random in nature. A channel it’s possible issue to interference, distortion, sounds, scattering and many others. plus the outcome is the fact that the gained signal may be stuffed with errors.

The Reception Path

The task of your Receiver is usually to accumulate the sign from your channel and reproduce it as the resource signal. The reception route of a Wireless Interaction Method comprises of Demultiplexing , Demodulation, Channel Decoding, Decryption and Source Decoding. From the parts from the reception path it’s very clear the process on the receiver is simply the inverse to that of transmitter.

The signal with the channel is obtained because of the Demultiplexer which is divided from other alerts. The person indicators are demodulated employing proper Demodulation Approaches and also the original information signal is recovered. The redundant bits within the message are removed utilizing the Channel Decoder.

Due to the fact the concept is encrypted, Decryption in the signal eliminates the safety and turns it into easy sequence of bits. At last, this signal is provided to the Resource Decoder to acquire again the first transmitted information or signal.

parts of motorcycle.

1. Drivetrain.
This is one of the most integral parts of a motorcycle. Without its drivetrain,
a motorcycle won’t function at all. Every motorcycle is powered by its
drivetrain where you can find the engine which conveys power to the rear drive
wheel through transmission. The transmission is attached to the engine and is
operated by the lever that is attached to the handlebars and the clutch.

2. Wheels.
What is a motorcycle without its wheels? Motorcycle wheels usually features
steel pokes or aluminum. The rear wheel of the bike is responsible for
configuration thus it is larger and least wider than the front wheel.

3. Tires.
Motorcycle tires are made from inflatable rubber. It has thread patterns that
may vary from one motorcycle to another and are designed for different surfaces
or riding condition.

4. Brakes.
This is an important part of motorcycles. There are two types of brakes- drum
and disc brakes – that are controlled by hydraulic system activated by
handlebar or foot levers.

5. Electrical
system. The electrical system of most motorcycles is lights which are consist
of the headlights, tail lights, directional lights and brake lights. The
electrical system of a motorcycle is also consisting of speedometer, tachometer
and odometer, fuel gauge, oil pressure gauge, radios and GPS systems.

6. Frame
and suspension. Steel and aluminum are two of the most common materials used on
the construction of motorcycle frames. Chassis also serves as the basis of a
