The high-power and high brightness led business begin to dominate?

Today, most of the R & D and production of LED business are in the exploring stage. Taking applications, sales, prices and other factors into consideration, more and more lighting companies in outreach claimed that the production of high-power and high brightness led products, but in fact it does not mean that the single 1W chip is the high-power LED to measure the difference of the power LED and low power LED products. The most critical is that the chip is not more than 1W. Therefore, the LED market is mature and standardize and the road is still a long way to go.

Throughout the current lighting market, according to the “hype” high to LED, from the application point of product design, the production cost of led projects, regardless of the manufacturer or the customer consumer groups, there are still some difficulty in the acceptance and now the LED technology is not well improved, the country is also not clear normative regulations, we can say now, according to the market, the high brightness led is still in the immature stage of development.

Lighting designer pointed out, the mainstream for commercial lighting is ceramic metal halide. In the next few years, it will be mainly for small ceramic metal halide, such as TC-.

According to the commercial lighting concept of the domestic market, we can easily find, the domestic commercial lighting design shop, there still exist misunderstanding of “the brighter the better.” At present, more and more owners want to own distinctive store design, seeking survival of differentiation. To create a good atmosphere for shopping, and guide their customers to focus on their feelings goods above.

Thus, when the the ritualistic lighting system is replaced by a new lighting system, its operating limit is indeed a lot of growth. Recalling the NVC early development ideas. To change the entire commercial space lighting atmosphere “is a good place to start, the exact terms of the development of existing commercial lighting is the most urgent need.

Throughout the commercial lighting sales channels, mainly based in the “network”, “sales” mode. For the lighting industry, the real competition is how to use more energy-efficient method to achieve better lighting effects.

 

The rated high brightness led is not enough caused memory homogenization fightting the price

40 watt LED lights is only spent 25 yuan, the same wattage incandescent only needs 2 yuan. Incandescent can be eliminated, and the LED lights up, which is a trend, but it does not like the five national ministries whol require as quickly and comprehensively. On the one hand, incandescent relative to the price advantage of the high brightness led, there are still short-term; On the other hand, the LED lighting business “homogenization, that price” sales strategy cast a shadow over prospects for the domestic market.

“Notice on the progressive ban on the import and sale of general lighting incandescent, according to five national ministries since October 1 this year to ban the import and sales of 100 watts and above ordinary incandescent lighting. Reporter visited the Shanghai Pudong New Area Hengda building materials market and found that although the “purchase incandescent client is not a lot”, yet various lighting stores also are equipped with incandescent lamps of 100 watts and above “100 watt incandescent 2.5 yuan each.

LED lamps compare with incandescent light, the greatest development force is energy saving and environmental protection advantages. However, as the costs are too high, resulting in high prices than traditional lamps a few grades, allowing consumers really willing to consume, the need to further decline is prices.

“40 watt high brightness led lamp is 25 yuan only, the same wattage incandescent is 2 yuan.” One shop sales staff said, although the price of LED lamps has continued downward trend, yet the real to reach consumers’  bottom line, still will take some time.

Experts said the high price is certainly a drag on sales of LED lights, which is a major culprit in the doldrums, but the public popularity of LED lamps have no improvement, which is also one reason. Talking about the LED, a lot of people will only think of the LED display, TV, but do not know to the original LED lighting can also be used, we may find this very strange, but this situation is very common. Even if part of an understanding of the LED energy-saving lamps, but the understanding is not comprehensive. Seeing high brightness led lights are just look at the power and price of the relevant parameters and they do not understand the relative specifications.

High brightness LED emerged in the market

High brightness LED brought many compelling features to car manufacturers. In spite that most of these features were derived from the working principles and similar production process of LED indicators-products are much older than themselves and well-proved.

 

High brightness LED brought many compelling features to car manufacturers.

 

LED taillights, LED signal lamps, LED working lights, LED brake lights can overcome shortcomings that much common in incandescent lights. Usually, vehicles will meet with frequent moderate shocks and vibrations, which may probably cut down the service life of incandescent lamps. Besides, the instantaneous surge current caused by temperature coefficient of filament resistance will accelerate the destruction of bulbs. Thermal loop-an important feature of break lights will definitely shortened the service life of incandescent lamps.

 

The instantaneous surge current generated by incandescent bulbs made the circuit protection and fault detection be more complicated. Automobile manufacturers have to set the fuse rating and the fault detection threshold large enough, to adapt the inrush current magnitude and duration without causing fuse blows failures or detection failures.

 

In contrast, when cars in shocks and vibrations that in the normal range of amplitude and frequency, structures of high brightness LED would be much stronger than incandescent bulbs. LEDs have compact structures (small sized) and light weight, which can reduce the mechanical torque generated by shocks and vibrations. The compact construction of high brightness LED contributed to the flexibility in the design of vehicle lighting applications. Within such limited space, designers hope that each compartment can meet the requirements of the overall design of the car. For example, some small cars would not set the CHMSL (Center High Mounted Stop Lamp) module in the rear cover. Instead, manufacturers made use of the feature of compact construction of high brightness LED and embedded them into trunk lids.

 

Designers also found out several problems about automobile taillights and the control system. These problems were also emerged in other systems that control devices were far apart with devices that under control. LED is essentially a kind of current devices. The combination of electron-hole pairs can emit photons. When increasing the input current, the compound speed and output luminous flux will also be raised. Definitely, the efficiency of this process cannot reach up to 100%, thus the a certain proportion of electrical energy will convert into heat. Unless in very poor working conditions, LED Lights will not break down like incandescent lamps does. But working in a over-heated condition for a long time will also accelerate the light attenuation of LEDs and consequently the service life.
