Q:What is the luminous flux of the LED light source of 1W?

At present, the LED light efficiency for indoor lighting is basically 80---120LM watts per watt.

Q:What is the light source type?

1, edge light type. A linear or point light source is provided on the back light of the side of the specially designed light guide plate. According to the actual needs, it can be made into two sides or even three sides. Edge light backlight generally can do very thin, but the light utilization rate of light source is thinner and thinner, and the utilization ratio is smaller. The technical core of 50%. is about the design and manufacture of the light guide plate. The most commonly used side lights are LED light, backlight, and CCFL backlight. Weizhi LED side light type back light source are WU, WH, WN, WL for unilateral style, WJ, WK, WB for bilateral type. With the development of LCD module to brighter, lighter and thinner, the side light CCFL backlight source has become the mainstream of the development of backlight. WQ products for the CCFL side light backlight weizhi.

Q:What's the difference between a LED bulb and a light bulb?

LED light source, long service life, incandescent lamp, fluorescent lamp, halogen lamp by using electronic light radiation emitting filament burnability, thermal deposition, light attenuation, and the LED lamp has the advantages of small size, light weight, epoxy resin packaging, can withstand high mechanical shock and vibration, not easily broken, the average life expectancy up to 100 thousand hours, LED lamp life of up to 5-10 years, the maintenance cost of the lamp can avoid frequent lamp replacement pain decreased greatly.

Q:Does the LED bulb really save power?

Advantage1, energy saving. The energy consumption of white light LED is only 1/10 of incandescent lamp and 1/4 of energy-saving lamp;2, longevity. Life of up to 100 thousand hours or more, for ordinary family lighting can be described as "once and for all."";3, can work in a high-speed state. If the energy saving lamp starts or closes frequently, the filament will blacken and will soon be broken;4, solid state package, belong to cold light source type. Therefore, it is easy to transport and install, can be installed in any micro and closed equipment, is not afraid of vibration, basically need not consider heat dissipation;5, the price is dropping. With the rapid progress of LED technology, its luminous efficiency is amazing breakthrough, and the price is decreasing constantly. An era of white LED's entry into the home is fast coming;6, environmental protection, no harmful substances of mercury. The assembly parts of LED lights can be easily disassembled and disassembled, and can be recycled by other people without recycling by the manufacturer.Summary: obviously, as long as the cost of LED lights is decreasing with the continuous improvement of LED technology. Energy saving lamps and incandescent lamps are bound to be replaced by LED lights. The country is paying more and more attention to lighting, energy saving and environmental protection, and has already vigorously implemented the use of LED lights.

Q:Which is better for CCFL backlight and LED backlight?

Comparison between CCFL and LED, LED is DC, low voltage; and CCFL is high voltage (600 Volts), of course, a small area of CCFL also has low voltage, but generally also has more than 300-400 volts. The light source of LED can be distributed freely according to size and application. CCFL is relatively fixed, it needs more diffusion material to do the dispersion of light, so that the brightness uniformity can be achieved.

Q:The problem of crystal light source

If you say white fabric bulbs don't have shadows, then make sure LED warm light is OK, because the LED light and the white light bulb are the same.

Q:What kind of light source is it for eye care table lamp?

The lamp. At present, LED is quite good, although there will still be more than energy-saving lamps or light bulbs expensive, but worth: LED choose to have the following points: first look at the shape of the LED lamp, must be a patch (there are many square yellow points a piece of aluminum substrate) if it is a small, spherical beads or a few high-power lamp, decisively abandoned, because those who are old, it is not good for your eyes, just before the LED has not been developed to mature technology push out;

Q:What is a surface light source and a side light emitting desk lamp? Has anyone used it?

Bought a back try, really can not see the light bulb, but also very soft, but also 8 files dimming, a word is very satisfied, decisively discarded before it PHILPS, hope it will be like the seller said in the last ten or twenty years, ha ha.

Q:What are the advantages and disadvantages of laser projection, LED projection and general projection?

First, long life, which is also one of the most important advantages for many consumers.Second, pure color, high color saturation.Third, moisture-proof, anti vibration.

Q:DLP projection light source UHP and LED contrast, thank you

The biggest difference between the UHP and LED light sources of the DLP display unit is brightness and loss,
