REVIEW: The advent of the 21st century, many new products have emerged, LED Recessed Spotlight lights such items are many friends at this stage are using the product, with low power consumption, high brightness advantages, LED Recessed Spotlight backlight what does it mean , In fact, Xiaobian do not quite understand, Xiao Bian made a special online information, the following is to explain in detail what is the meaning of LED Recessed Spotlight backlight, and LED Recessed Spotlight backlight and ccfl backlight that good, hoping to help everyone.
LED Recessed Spotlight backlightLED Recessed Spotlight backlight what does it mean
What is the meaning of LED Recessed Spotlight backlight, LED backlight refers to the use of light-emitting diodes as the LCD backlight, and the traditional cold cathode fluorescent tube backlight, low power consumption, low heat, high brightness, Long life and other characteristics. LED backlight is what it means, LED backlight brightness is high, the brightness will not drop for a long time and the LED backlight body thinner, the appearance is also beautiful, the color is also relatively soft, with the hard-screen panel color allows the eyes more comfortable , All LED backlight has, low power saving environmental protection.
What is the meaning of LED backlighting, LED light source is composed of a large number of grid-like semiconductor, each 'lattice' has a LED semiconductor, so that the LED backlight successfully achieved the flatness of the light source. The planar light source not only has excellent brightness uniformity, but also does not require complex optical path design, so that the thickness of the LCD can be made thinner, but also has higher reliability and stability.LED Recessed Spotlight backlight and ccfl backlight that good
LED backlight and ccfl backlight that good, CCFL and LED comparison, LED is DC, low voltage; and CCFL is high voltage (600 V), of course, a small area of the CCFL also has low pressure, but generally there are Over 300-400 volts. The LED's light source can be freely distributed according to the size and application. CCFL is relatively fixed, it needs more diffuse material to do the light dispersion, in order to make the brightness uniformity to meet the requirements.

From an extension point of view, (a) LEDs have a wider color gamut and a saturation of more than 105%, whereas CCFLs are narrower and make up only about 70% of the most. (B) LED's Speed is very fast, can help the LCD to eliminate the phenomenon of tailing; (c) LCD a big flaw is 'black screen' is not black, if using LED dynamic control, then, can be a good solution to this problem; (d) LED Of the current can be adjusted; (e) LED is a green product, does not contain mercury, is a solid light source, good shock resistance, low voltage safety. So LED in the future is likely to be widely used.
On the issue of life expectancy, although the life of the LED is very long, but if the user overheating, or will lead to a decline in life expectancy, and now we take a dynamic approach to control, LED life can be done 100,000 hours or more, according to the driver Different, to meet different needs. CCFL usually only 20,000 to 50,000 hours of life.
