WHAT IS THE COLOR TEMPERATURE OF LED HOME LIGHTING?

Many people know that they want white or yellow light, so this color light is not a random choice. These different color temperatures can change people's different emotions. For example: people in the north habitually choose yellow light lamps, while people in the south habitually choose white light as the majority; so why is this?

Because yellow light belongs to warm-toned light, while white light belongs to cool-toned light, people in the north will habitually choose warm-colored light due to climate and other factors, while southerners will habitually choose cool-toned light.

1. The concept of circular LED lighting color temperature

The color temperature of home circular LED lighting is represented by the absolute temperature "K", which is to heat a standard black body. When the temperature rises to a certain level, the color begins to change gradually from dark red-light red-orange-yellow-white-blue. A certain light source When it is the same color as the black body, we call the absolute temperature of the black body at that time the color temperature of the light source.

Because the correlated color temperature is actually close to the light color of the light source by the black body radiation, the evaluation value of the light color performance of the light source is not an accurate color comparison, so two light sources with the same color temperature value may be different in light color appearance There are still some differences. The color temperature alone cannot know the color rendering ability of the light source to the object, or how the color of the object is reproduced under the light source. Correlated color temperature of different light source environments. The color temperature of the circular LED lighting source is different, and the light color is also different. The color temperature below 3000k has a warm feeling and achieves a stable atmosphere; the color temperature of 3000k-5000k is the middle color temperature, which has a refreshing feeling; the color temperature above 5000k has a cold feeling.

2. Different colors represent the color temperature corresponding to the circular LED lighting

We can clearly see that the corresponding color represents the corresponding color temperature; then in the test report of the lamps, we make a batch of lamps, for example, to produce 100,000 lamps, then at this time, can it be a sampling test, in different batches When the light source is produced for the first time, it will have a certain impact on the color temperature of the finished lamp, that is to say, as long as we are within a certain color temperature of plus or minus 100-200K, it is considered a normal range.

Therefore, when we go to the lighting factory to buy lights in the future, we can test the specific color temperature. Then the quality of a circular LED lighting is not only determined by the color temperature of the lamp, but also important parameters: light effect, display, luminous flux, Illumination, whether there is glare, whether there is strobe, and the angle of light are determined by these parameters.
