Are LED lights used in foreign countries?

The leading industries of the LED industry are all abroad, do you say much、。。

more of them have been applied abroad for a long time .

In fact, LED has existed for a long time ......Around 2000, there were enterprises in China that produced civilian LED lights, not to mention medical ones.

LED lamps have long been flooded in the Chinese market, and domestic LEDs are very easy to use.

[Currently LED lights.]

Disadvantages] 1. First of all, the quality is unstable, and the LED lamps that advertise a 10-year life may be broken in 1 year.

2. It is heat dissipation, which may be the biggest problem faced by LED lamps at present. Now the heat dissipation of LED lights is very passive.

3. With the addition of heat dissipation devices, the weight of LED lamps and lanterns has increased a lot. At present, LED lamps and lanterns should take into account heat dissipation, and also consider the weight of heat dissipation materials, which is a dilemma, and the only thing that can be done is to find their balance.

4. The last one is **, at present, under the same brightness, the efficiency of energy-saving lamps is roughly at the level of 1W1 yuan, while LED energy-saving lamps are basically maintained at the level of 1W5 10 yuan.

The biggest bottleneck is heat dissipation and packaging, as well as the efficiency of converting electrical energy to light energy, which seems to be only 30% efficient now! 70% is wasted.

1.Lack of an international brand.

2.Lack of core technology.

3.Zhongshan messed up the **...

According to the characteristics of the luminous tube, it is divided into round lamp, square lamp, rectangular, surface luminous tube, lateral tube, micro tube for surface mounting, etc. Round lights are divided into 2mm, 20mm and so on according to their diameter. In foreign countries, 3mm light-emitting diodes are usually counted as T-1; Denote 5mm as T-1 (3 4); Denote as t-1 (1 4).

The angular distribution of luminous intensity in a circular can be estimated from the half-value angle size. According to the angular distribution of luminous intensity, there are three categories: (1) High directivity.

It is usually encapsulated in a pointed epoxy or with a metal reflector cavity without the addition of scattering agents. With a half-value angle of 5° 20° or less, it has a high directivity of round reeds, and can be used as a local illumination source or in combination with a light detector to form an automatic detection system. (2) Standard type.

It is usually used as an indicator light, and its half-value angle is 20° 45°. (3) Scattering type. This is an indicator with a large viewing angle, a half-value angle of 45° 90° or greater, and a large amount of scattering agent.

Let's explain it from the following aspects:

**Chaos, uneven quality level, single sales channel, no complete market channel, no complete breakthrough in technical problems, breakthrough, product ** is very expensive, 4-5 times that of ordinary lamps.

However, the energy saving is more than 60%, so under the policy of ten cities and ten thousand lamps, it is still more supportive, but to do the first project, you need to have connections, or you have, or yours have.

If you do commercial lighting, the sales are relatively small, unless you have a lot of engineering resources, and you are still in the stage of a few people eating crabs for civil use, which is too expensive.

But now is a good time to enter the market, late there is no opportunity, early, sacrificed, you have to evaluate your own technology and network resources, to see if it is not suitable for this industry, LED profit return is still very high, I hope it can help you.

First, the consumption level determines that the LED market is limited;

Second, the lack of promotion and publicity has led to the benefits of LED not being recognized.

Generally speaking, the potential of the mainland market is quite large, and the key depends on the market positioning of the products it handles.

LED lamps are Chinese name for energy-saving lamps, which are the progressive products of incandescent lamps. LED lamps and incandescent lamps have the following advantages:

1. Energy saving. The energy consumption of white LEDs is only 1 10 of incandescent lamps and 1 4 of energy-saving lamps

2. Longevity. The life span can reach more than 100,000 hours, which can be described as ordinary home lighting"Once.

3. It can work at high speed. If the energy-saving lamp is turned on or off frequently, the filament will turn black and break down quickly.

4. Solid-state package, which belongs to the type of cold light source. So it's easy to transport and install, and can be installed in any miniature and enclosed device, without fear of vibration, and basically no need to think about heat dissipation.

5. LED lighting technology is advancing with each passing day, and its luminous efficiency is making amazing breakthroughs, and it is also constantly decreasing. An era of white LED luminaires entering the home is rapidly approaching.

6. Eco-friendly, no harmful substances of mercury. The assembly parts of the LED lamp can be very easy to disassemble and assemble, and can be passed by others without the manufacturer**.

Summary: Obviously, as long as the cost of LED luminaires decreases with the continuous improvement of LED technology. Energy-saving lamps and incandescent lamps will inevitably be replaced by LED lamps.

At present, the country is paying more and more attention to lighting energy conservation and environmental protection issues, and has been vigorously promoting the use of LED lamps. In particular, the first transformation of street lamps is the first LED street lamp, which indicates that the LED street lamps must be used to replace energy-saving lamps and incandescent lamps.

You can go to the Philips official website to see the new LED light series instead of ordinary incandescent lamps.

Wide, very wide, very wide!

Almost all lighting can be replaced by LED lights, as well as the use of special functions, such as displays, chemical reaction catalysis, and even your fillings need LED lights to cure your filling materials.

Very wide, LED has many advantages such as energy saving, long life, etc., occupies a dominant position in the field of lighting, widely used in lighting, medical, display, aviation, military, automobiles, it can be said that where there are electronics, LED is used

1. Innovative technology continues to develop. At this stage, xenon headlights, LED headlights and laser headlights are the three mainstream products in the automotive lighting market. Technological innovation has led to the development of organic LED lamps, which enable LED headlights to provide better lighting conditions.

2. Ambient lighting in the car is becoming more and more popular. Interior ambient wide head-type lighting is used in high-end automotive products, but with the cost of LED lights decreasing year by year, it is now used by more and more low-end vehicles.

3. There is a lot of room for the development of laser and organic LED lights. Laser and organic LED lamps belong to the advanced technologies in automotive lighting. However, due to cost reasons, it is generally only used in luxury cars. But as the cost falls, laser and organic LED lamp applications will become more common.

In 2015, with the intensification of competition, coupled with the smoke of the first competition, LED lighting has become a "red sea", with the continuous growth of the automotive LED market, coupled with the current average gross profit margin is generally more than 20%, so that LED manufacturers are actively engaged in the field of LED automotive lighting. The monopoly pattern of Osram and Philips on the automotive lighting market will be broken.

At the same time, as Mercedes-Benz, Audi, BMW and Land Rover and other high-end car brands have adopted LED lights as the lighting equipment of their first cars, LED lights have gradually become the new favorite of the automotive lighting market. Many lesser-known car brands, such as Opel and Seat, have followed suit. Yes, in the near future, LED headlights will be a common lighting device in the automotive lighting market.

According to the global white LED market research report published by Fuji Chimera Research Institute in Japan, the automotive LED market centered on interior lights accounts for a small proportion of the entire white LED market, but it is expected to achieve significant growth in the future; It is expected that the relaxation of headlamp restrictions and the increase in the brightness of white LEDs will lead to a significant increase in the number and performance of white LEDs for automobiles in the future.
