Embodiment

[0063] Embodiment: Select four single-chip LEDs to synthesize a four-chip LED light source with a color temperature of 4000K. Four single-chip LEDs red LED, amber LED, green LED and blue LED with spectral energy distribution as image 3 As shown, the corresponding chromaticity points are as Figure 4 As shown, where point X is the intersection point of chromaticity, and the corresponding chromaticity point of 4000K color temperature is located on the Planck curve. If the proportion of amber LEDs is set to t, each single-chip LED is linearly proportional, such as Figure 5 shown. For the radiation luminous efficiency LER, the physiological radiation efficiency parameter C / P corresponding to the photobiological effect performance, and the mesopic efficiency parameter S / P or M / P corresponding to the mesopic effect, the three parameters all conform to the inverse proportional function relationship and present a monotonic relationship. Such as Figure 6 shown. For various appl...

Abstract

The invention discloses a spectrum optimization technical method for a high-performance four-chip LED, which comprises: step 1: executing a four-chip LED spectrum light color mixing method; step 2: carrying out spectrum synthesis chromaticity selection of the four-chip LED; step 3: optimizing the lighting effect of the four-chip LED; step 4: optimizing the color rendering of the four-chip LED; step 5: optimizing the radioluminescence efficiency of the four-chip LED; step 6: optimizing the mesopic vision radiant efficiency of the four-chip LED; step 7: optimizing the photobiomodulation of the four-chip LED; and step 8: carrying out comprehensive performance optimization on the radioluminescence efficiency, mesopic vision radiant efficiency and photobiomodulation of the four-chip LED. According to the spectrum optimization technical method for the high-performance four-chip LED, not only can performance on a certain aspect of a four-chip LED light source be optimized, but also the integral performance can be optimized; and meanwhile, a plurality of single-chip LEDs can be optimized to select chips applicable to synthesis of the four-chip LED.

Description

technical field [0001] The invention relates to the field of lighting technology, in particular to a high-performance four-chip LED spectrum optimization technology method. Background technique [0002] Multi-chip LED (Multi-chips of LED or Multi-packages of LED) is an important type of white LED, but due to the inconsistent light attenuation of each single chip, it causes the problem of light color consistency, making it suitable for functional lighting applications It is not as extensive as PC LED (Phosphor converted LED), and at the same time, the advantage of multi-chip LED spectrum flexibility cannot be brought into play, which greatly limits its application. In addition, for the application of white LEDs, most of the research only focuses on the efficiency and color rendering performance of white LEDs, and it is not enough to focus on these properties. For example, some studies have shown that inappropriate spectral forms of light sources will cause health hazards. Ca...
