Which of the two light sources is better? Why

UV LED flood light source has the characteristics of power saving, natural light, wide irradiation area, uniform light spot, longer life, stronger illumination, etc., LED ultraviolet balanced light source for LCD PCB and so on. More energy-efficient and environmentally friendly than traditional mercury lamps! If you want to know more about it, you can consult Futanxi, products and services:

Thank you!

I copied it.

Comparison between CCFL and LED, LED is DC and low voltage; The CCFL is high-voltage (600 volts), of course, there are low-voltage CCFLs in small areas, but there are generally more than 300-400 volts. The light source of the LED can be freely distributed depending on the size and application. CCFL is more fixed, and it needs more diffusion materials to disperse the light, so that the uniformity of brightness can meet the requirements.

From the perspective of extension, (A) LED has a wider color gamut, and the color saturation can be more than 105, while the CCFL is relatively narrow, and most of them can only achieve about 70; (b) The speed of LEDs is very fast, which can help LCD eliminate the phenomenon of tailing; (c) One of the major defects of LCD is that the "black screen" is not black, if it is controlled by LED dynamics, it can solve this problem very well; (d) The current of the LED can be adjusted; (e) LED is a green and environmentally friendly product, does not contain mercury, is a solid light source, good shock resistance, low voltage safety. Therefore, LED is likely to be widely used in the future.

On the issue of life, although the life of LED is very long, if the user overheats the use, it will still lead to the decline of service life, now we take a dynamic approach to control, so that the life of LED can be more than 100,000 hours, according to the different drivers, can meet different needs. CCFLs typically have a lifespan of only 20,000 to 50,000 hours.

In terms of the characteristics of CCFL and LED, the breakdown voltage and working voltage of CCFL are relatively high, and the voltage of LED is very low. Therefore, the safety performance of LED is very good.

In summary, LED is better than CCFL.

Of course, it is LED, which is power-saving, energy-saving and environmentally friendly! The popularity of LED is also the trend of the times, and it will happen sooner or later.

The landlord didn't figure out the LED vs. the LCD

LCD is what we often call liquid crystal, and the display device is LCD, and the light source it uses can be a classic gas discharge gold halide lamp or an LED light-emitting diode.

The so-called LED projectors on the market are not LED as display devices, but as light sources. Most of its display devices are still LCDsSpecial projectors are exceptional.

The characteristics of LED: high light efficiency, energy saving, safety (low voltage operation), if you want to DIY projector is a good choice. Because their own DIY or domestic projectors are generally 5-inch 6-inch 7-inch screens, this space can be well arranged LEDs

Some imported machines will not choose LED as the backlight, because the size of the professional projection LCD is very small (it helps optical adjustment, the light flux in the center area and the four corners is uniform), and the light flux of the LED arranged in a small space is not able to be compared with the traditional metal halide lamp.

In addition, LED has the advantage of having a narrow spectrum. Monochromaticity is good, but if it is used in projectors, this is a disadvantage. Of course, LED can use red, green, blue, and amber to make up for this defect, but the cost will be very high.

The clarity is related to the resolution of the LCD and the design of the optical lens and lamp chamber, and the relationship with the light source is not very obvious. If the light source in the lamp room of the projector is scattered, the dispersion will directly affect the clarity. A feeling of gray haze or fog. This LED is relatively better.

The same LCD, LED projection, out of the effect, there is a harder feeling, the color is distinct. That is, the so-called cold tone, the effect of projection projection by ordinary lamps is better. Because of its wide spectral coverage.

To sum up, LEDs have their own advantages and disadvantages compared with gas discharge lamp gold halides, depending on the preference of the landlord.

If you have a different opinion, please laugh it off.

The LEDs are better, in addition to that, when you go to choose, you have to look at the lumens, etc., and then you can see the life of the bulb in the settings, because some are demo machines, and they may also be cleared, but you have to check it yourself.

It's definitely the LED light source that is good, I'm not a professional, but I've seen a comparison of these two lights on TV.

Domestic: Foshan lighting products are good.

Foreign: Philips, Hitachi, Panasonic, LED lights are reliable, ***.

LED (light-emitting-diode Chinese meaning light-emitting diode) is a semiconductor that can convert electrical energy into visible light, which changes the principle of incandescent lamp tungsten luminescence and energy-saving lamp trichromatic powder luminescence, and uses electric field luminescence. According to the analysis, the characteristics of LED are very obvious, long life, high light efficiency, no radiation and low power consumption. The spectrum of LEDs is almost entirely concentrated in the visible frequency band, and its luminous efficiency can exceed 150 lm W (2010).

The results show that the luminous efficiency of ordinary incandescent lamps is 12lm W and the life is less than 2000 hours, the luminous efficiency of spiral energy-saving lamps is 60lm W and the life is less than 8000 hours, the light efficiency of T5 fluorescent lamps is 96lm W and the life span is about 10000 hours, and the white LED with a diameter of 5 mm can exceed 150lm W and the life span can be greater than 100000 hours. Some people also ** that the upper limit of the future LED life will be infinite.

Relatively speaking, light sources can be divided into three light colors: cool, neutral and warm.

Of course, light color is only a feature of major products, and it is impossible to distinguish the quality of the light source.

A simple test method can be done by taking a reference object, preferably some white paper, against the light source after the power is on. Put on the side of the light source, the color of the light source on the paper, the closer to the white, the better, the light source with relatively poor quality is basically mapped out after it is tended to be cyan-colored!

Ordinary energy-saving lamps contain mercury, if the bulb is damaged, it will affect people's safety, the average life span is 1 year, and it needs to be replaced again when it is broken every year, and the shape is not very beautiful, and the luminous color is only white and warm. However, LED energy-saving lamps are all-solid luminaires, solid cold light sources, epoxy resin encapsulation, and have a service life of up to 5 years, which is 10 times that of energy-saving fluorescent lamps. Once installed, it is guaranteed that it will not be replaced within 5 years.

The appearance shows the noble and gorgeous generosity. LED energy-saving lamps are colorful in color, such as: white, blue, etc.

LED lamps are energy-saving and environmentally friendly, shockproof, waterproof, miniature, high brightness, easy to dim and other advantages. With the gradual implementation of the global plan to phase out incandescent lamps, the green lighting industry will rise. The new generation of LED green light source will surely trigger a revolution in the global lighting field in the 21st century.

We'll just have to wait and see.

Under the same illuminance and voltage, the power consumption of three lamps.

I specialize in competitive analysis.

To be honest, with LED light source, the cost is too high, so it's better to change to a straight tube fluorescent lamp. Best value for money! Hehe.

If you use it, you must use LEDs, and wait for 3 or 4 years to talk about it, because at that time, ** will drop a lot, **20 30 will decline every year, and performance will rise 30 50 per year.

But if you must use LED now, you should choose Philps, a big brand, guaranteed, and the most complete product category. The R&D team is the largest and best in the world, and the comprehensive level of product performance is the best in the world.

Hope it works for you. My answer, thank you!

Shenzhen Tianke Optoelectronics, their LED flood light source shipments are the largest, and the industry qualification is the oldest.

The conventional specifications of Mitsubishi DLP products have two light sources: ordinary light source and LED light source, such as 50" 60" 67" 80'; However, the newly developed three sizes of products only have LED light sources for sock rolls, and are not equipped with ordinary light sources, such as 62" 70" 72". The key change is mainly to announce that the bright afterglow light source is a high mercury lamp, and the production process has a certain pollution to the environment, and the life span is shorter than that of LED lights. Now the industry trend is mainly LED light source and laser light source, so the new specification of the product no longer uses ordinary light source.
