Whether the color temperature distribution of the high-power wall washer is uniform or not will directly affect the lighting effect; and the color temperature and the color rendering index are related to each other, and the change of the color temperature will cause the color rendering index to change. The thermal resistance of the high-power wall washer directly affects the heat dissipation of the LED device. The lower the thermal resistance, the better the heat dissipation; the higher the thermal resistance, the poorer the heat dissipation, so that the temperature of the device increases, which will affect the wavelength shift of the light. Wall washer manufacturers based on experience, the temperature rises by one degree, the light wavelength must drift 0.2~0.3nm, which will directly affect the luminous quality of the device. Excessive temperature rise also directly affects the service life of the W-class high-power wall washer. Color rendering is an important indicator of white LEDs, and the color rendering of white LEDs used for lighting must be above 80.

    The high-power wall washer has higher energy-saving properties, and now everyone pays more attention to saving resources, so this is very good. And the high gloss is relatively good, suitable for many occasions, large shopping malls, museums and other places. It is something that many people will choose. And also has the characteristics of long life, so this is what many people will choose.

The industry uses a large number of single 0.06W power, its brightness can achieve 7LM, we temporarily calculate according to ordinary 6LM, if we want to achieve 1W power, we need to use 17 same LEDs, with a total brightness of 17 *6102LM, which means that it can achieve 100LM/W; if we use a single chip with 1W power, its output brightness can be up to 80LM, and the commonly used one is generally around 60LM. This is a major difference in brightness. It can be seen that for home use, we still have to choose low-power LEDs.

    The high-power wall washer that integrates so many advantages makes us feel that it is a valuable work to promote the use of it, but it also has some shortcomings, such as low color rendering in white light lighting. At present, the white light LED produced with yellow phosphor and blue light has a color rendering index of about 80, which is okay for general lighting.

    However, it is insufficient for some places with high color resolution requirements. Although the color rendering index can be increased to 90 or higher by adding appropriate red phosphors and other methods, there is still a certain gap compared with the 99 of incandescent lamps, and its efficiency Will be affected, so in terms of color rendering, the high-power wall washer still needs to be improved to a certain extent. As for the problem of high prices, in fact, considering the overall cost, the use of high-power wall washers in many occasions still saves a lot of costs.
