What do you know about LED light

Because most of the LED technology is still too inadequate, so for the first using on lamps drawbacks include light quality (CRI, consistency, and color temperature) is poor, heat is not easy, and the price is high, improper cooling which will result in brightness LED lighting components and circuit life accelerated decay.

With the mmanufacturing technology advances, the above-mentioned drawbacks, including LED thermal resistance decreases, also enhance the quality of light. 2008, cold white LED luminous efficiency has reached 100 Lm / W, and warm white LED luminous efficiency is expected in 2010, also available from the 70 Lm / W increased to 100 Lm / W.

Compared with other common sources, incandescent light bulbs is about 15 Lm / W, fluorescent lamp about 45 ~ 60 Lm / W, HID lights about 120 ~ 150 Lm / W, LED luminous efficiency is clearly a competitive advantage gradually; following is a LED lighting lamps and other’s common comparison:



Lighting system
features
White light LED

Less heat, wide operating environment, miniaturized, shock-resistant, concentrated beam.
Fluorescent lamp
Power saving, but friable waste mercury will cause pollution problems.
incandescent light bulbs
Low efficiency, high power consumption, short service life, fragile.


An amount of advantages goes with application them. When compared to beaming and beaming ablaze bulbs. LED light bulb is abutting to 1/10 beneath ability consumption. LED light bulb also abides 50 to 100 times best as adjoin accepted bulbs, or accumulation 100,000 hours' use adjoins 10,000 hours for CFLs or bunched ablaze bulbs. LED light bulb is abundant added bunched in measurement and are sturdier.
