The luminous color can be adjusted to the time of day and the human biorhythm, for example by combining white and colored light emitting diodes. When the sun shines through the window in the afternoon, the intelligent lighting system stagelessly dims the LED light on our businessman's desk o...
High Luminous Efficiency 180 Lm/W Street LED Light with Smart Control System, Find Details and Price about Road Lighting Street Luminaires from High Luminous Efficiency 180 Lm/W Street LED Light with Smart Control System - Ellins Optoelectronics Co., Lim
In Fig. 1c, the blue LED light is converted to white through a yellow CC film with an efficiency EQEQDEF ≈ 0.7348. Some optical films, such as DBR, diffuser, BEF and DBEF, may be added to the BLU, corresponding to a luminous transmission TBLU ≈ 0.9. Then, the light is...

As technology advances, new LEDs of higher power and efficiency emerge. However, there is still the problem of heating the LEDs which reduces the luminous efficiency. There are several efforts that present analysis of thermal dissipation of HP-LED lamps and luminaires [17,18]. However, several ...
In addition to display applications, since 2000, Micro-LED has been studied to improve the luminous efficiency of high-intensity lighting because of its relatively high light extraction efficiency, better current expansion and lower self-heating effect [14,15,16]. In 2000, Jiang et al., of ...
In the 2000s, LCD TVs took over the high-definition market and represented a huge step over old standard definition CRT televisions. LCD displays were even a major step above HD rear-projection sets that weighed well over 100 pounds (45.4 kilograms). But LED technology changed the market. ...
This allows for a significant number of hues and tones, resulting in finer and more exact color definition. Accurate Current Monitoring and Matching Each of the four LT3476 current monitor thresholds is trimmed to within 2.5% at the full scale of 105mV. The LT3003 drives three separate ...
