How do the junction temperature of LED light generate

Why the LED light especially the high power LED lights including the high power LED flood light generating the heat is because that all of the electricity inputted is not turn into light energy , but considerably majority of which is transformed into heat. LED light efficiency is currently only 100lm / W, the electro-optical conversion efficiency is only about 20 to 30%. That is about 70% of the electrical energy wasted into heat .

high power LED flood light

Specifically , the junction temperature of especially the high power LED flood light and other power LED light is generated due to two factors .

1 . Internal quantum efficiency is not high , that is, when the electron recombines the hole, which can not produce 100% of all photons, commonly referred to as the ” current leakage ” of carriers leaving the PN zone composite rate. Leakage current times the voltage is the power of this part, which is converted into heat , but this part does not account for the main component , because the internal photon efficiency is close to 90%.

2 . photons Internally generated can not be fully emitted to the outside of the chip and finally converted to the heat, which is the main part , referred to that the external quantum efficiency is currently only about 30% , most of which is converted into the heat .

Although the light efficiency of incandescent is very low , only 15lm / W or so, the considerably majority of the electrical energy light energy is converted into heat , which is that same as the high power LED flood light and other LED lights or other lamps,the rest electricity is converted into light radiated since most of the radiation is infrared therefore very low efficiency, but eliminating the problem of heat dissipation .Browsing http://www.lead-lighting.com/products/sid125-1.htm for more information about the high power LED flood light.

Why so slow the development of China’s LED lighting

1 , the low-end market impact :

Currently the economic constraints the development of public LED lighting including thehigh power LED flood light and other commercial or industrial LED lights in a lot of Chinese countries, the towns and rural areas accounting for 70 to 80% of the area of China are particularly prominent. So cheap, poor performance of incandescent and fluorescent lamps still flood the market,resulting in that the lighting manufacturers have to compete for the low-end market , the price war is inevitable . They are not developing new lighting products but to find ways to save the cost of materials of the LED lighting especially the high power LED lights such as high power LED flood light and general lighting ,for instance ,the chip of high power LED flood light and other LED lights is not original, the heat sink is most common, etc.,. moreover the vendors have not enough capacity to develop and research the high power LED flood light and other commercial and industrial LED lights but is pretty comfortable for the low-end market.

2, the management level of manufacturer is not high :

Most of Chinese lighting manufacturers are small businesses , of which there are many private enterprises. Although a few passed the ISO9000 international certification , etc., but majority of the enterprise specializing in high power LED flood light and other commercial and industrial or household LED lighting is still manual workshop adopting family -style management , which is lack of construction of a modern enterprise system.

3, the impact of foreign advanced LED lighting products :

With the influx of foreign advanced LED products , new technologies, new ideas are bringing to the Chinese people but also the impact of the domestic market. The current high-end high power LED flood light and other commercial and industrial LED lighting products are dominated by the US and Japan, a lot of commercial buildings and stadiums, squares built by provincial cities generally use the high power LED flood light and other quality imported LED lamps over the past two years, as long as economic conditions permit. Some domestic manufacturers is unable to compete with foreign brands , only to abandon the development of high-end high power LED flood light and other commercial and industrial LED lighting products , bringing some negative impact on domestic developments of LED lamps or other lamps.Surfing http://www.lead-lighting.com/products/sid125-1.htm for more information about the high power LED flood light.

LED lighting particularly the commercial high power LED flood light and other commercial LED lights or household LED lighting can bring many significant benefits and also faces many challenges to become a truly mainstream technology , especially in terms of cost , standardization, and public awareness. The Commission wants to ensure that Europe will not lag behind other major economies which also tried to develop high power LED flood light and other solid-state lighting.

The Commission estimate that lighting account for 14% of total EU electricity consumption of at present, accounting for 19 % of that of the world. But the proportion is rapidly rise in the European cities , these areas account for half of the total lighting electricity consumption , which means the development of high-efficiency LED energy particularly the high power LED flood light and other LED lighting is making a significant impact on energy needs .

However, many of the city’s government is not enough awareness of this point , and some cities are also facing other challenges. In the Green Paper the European Commission , said: ” Many cities do not want to widely use the high power LED flood light and other solid-state lighting in the field of outdoor lighting , mainly because the relatively high upfront investment costs conflict with a tight annual budget and there are some others. reasons, such as lack of quality certification system and developed standards and norms . “Browsing http://www.lead-lighting.com/products/sid125-1.htm for more information about the high power LED flood light.
