LED interior lighting precautions
POSTED ON AUGUST 21, 2013 BY ADMIN IN LED KNOWLEDGE, LED LIGHTING WITH THERE ARE NO COMMENTS
Throughout the development of LED industry, current LED outdoor lighting and landscape lighting has been relatively mature, but on the other hand, LED interior lighting still in its infancy in many countries. But as many countries have promulgated ”road map” to phase out incandescent bulbs, we can believe LED interior lighting will have explosive growth in the next few years, it entering the great prospects.
In order to enter the large scale interior lighting market, LED lighting need fulfill the following conditions:
1. LED lamps color temperature around 4,000 K, because 4000K is the best choice for indoor home lighting. Warm white make the whole environment more warm and relaxed; and cool white let people feel clean, efficient and bright, more suitable for office and outdoor lighting.
2. Prolong LED lighting life, improve system reliability. This can be improved by optimizing the whole LED system.
3. LED light source need to be compact, efficient, and variety colors available.
4. Power Conversion function: Convert the AC or batteries to low voltage and constant current efficiently.
5. Control and drive: The use of electronic circuits to achieve LED constant current driver and control.
6. Thermal management: To achieve a longer life, control the LED junction temperature is very important, thermal analysis is also essential.
7. Optical elements: lens, reflector and LGP materials are the key devices to focus the light on the target area.
