T8 1.2m color led tube dimming RA96 6500k Langte Lighting

Langte brand split T81.2m color led tube RA96 6500k

   Langte standard color matching light box LED tube is often used in toy color matching light box, printing and dyeing color matching light box, plastic electronic color matching light box, paint color matching light source box, ink color matching light box, and printing color matching light box. The advantages of using led lamps are long life, saving electricity costs, and no auxiliary circuits are required.

With a dimmer, brightness adjustment can be achieved. The color temperature display index will not change.

  In practical applications, it is found that when observing the same picture under the same two light sources with a color temperature of 6500k, one is the opposite color light source and the other is not, it will be found that the color of the same picture will change under the two light sources. The three elements of color are quite different, and the characteristics of color are the result of the perception of colors of different wavelengths.

  Ambient color, the color of the surrounding environment of the object due to the reflection of light, the change in the color of the object is called the environment color. Especially the reflective part of the dark part of the object changes more obviously. This is because the spectral energy distribution of non-light sources is very different from that of sunlight, and certain wavelengths of monochromatic light components are missing from these spectra.

2. Concept description

  1. Color temperature requirements: The concept of color temperature is the temperature of the black body when the chromaticity of a certain light source is the same as the chromaticity of the black body at a certain temperature. A black body is an object manufactured that absorbs all radiation of any wavelength at any temperature. Generally, the color temperature of the light source can only be determined by the color temperature of the chromaticity of the light source and the chromaticity of the closest black body. The color temperature determined in this way is generally referred to as the color temperature. Therefore, the standard light source is a color temperature standard, usually 6500k, which refers to the color temperature, so as to truly simulate the environment of sunlight.

   2. Color rendering index: the color rendering index of the LED tube should be above 95. The main display index R9/R10/R12 can reach 95. Only high color rendering index can simulate sunlight and restore the true color of the color.

  3. Color management, although the quality inspector QC has carefully compared the color of the goods, but because the ambient light source is not standard or inconsistent with the light source used by customers, the colors seen under different light are different, and the color difference of the goods is difficult to judge. . When customers inspect the goods, they will complain or even return the goods because the color difference exceeds the standard range, which seriously affects the company's goodwill. To effectively solve the above problems, a useful method is to test the color of the goods under the same light source and controllable conditions.
