The key dissipation of LED led road light technology: light, heat

Although the LED industry in recent years, rapid development, but it still lacks the authority of the technical standards, resulting in the industry as a whole mixed, the promotion of a wide range of very unfavorable. LED street light in a relatively high technical difficulty, led road light,  lack of technical standards for the problems caused by very obvious. Many excellent technology of LED manufacturers and integrators, and do not know how to design a practical lights, applications department can not tell the specific requirements. For example, led road light, many manufacturers in order to solve the LED heat dissipation problem, design a “hollow type” shade. But poor on the street, so the shape of “shelter” function is not suitable for street lights.

The key dissipation of LED led road light technology: light, heat

Although government support, led road light, the LED street lamp market is the rapid development, but in order to truly get the long-term development of the LED street lamp market is still facing serious challenges. At present, the main problem facing addition to the high cost of LED high bay lamp products include: light, heat and power systems.
Light sources: one is to enhance the LED luminous efficiency, the other is to improve the arrangement of the light source. At present, a large part of LED lamp products on the market, LED light source is arranged in a lattice structure, this way of the biggest advantages is to help to solve the heat problem, but due to lateral irradiation distance of this structure is not enough, the light distribution larger, resulting in concentrated light distribution can not be achieved reflective cup, you need to use the second lens to achieve independence with light, which are higher for the selection of the secondary lens, led road light, secondary lenses of different materials there are some problems affecting product the results. If handled properly, the lens will also affect the lighting effects and clarity of the road.
Power: Unlike traditional lighting products can be directly connected to AC power, the LED is a low-voltage driven devices, led road light, and requires constant current drive, which requires re-design the power system of LED lights. LED power costs account for about 10% -20% of the overall product cost, power system, but off will largely affect the life of the product.

Taiwan LED road light or will be reduced to a low margin business model

Taiwan LED road light or will be reduced to a low margin business modelSouth Korea’s Samsung and LG will be launched in the second half of next year its own brand 60 watt LED light bulb, led high bay, the price is only 10-12 U.S. dollars, one stroke LED lighting to the sweet spot.

South Korean LED in the government is trying to foster development of the STC of the world’s third largest long crystal factory, led road light, Samsung impressive addition to the panel, even the LED epitaxial company merged into Samsung, Samsung LED epitaxy and packaging technology, and music LG (LG), led road light, both introduced low-cost LED bulbs to create brand to demonstrate its one-stop strong industry position, plans to replace the international lighting giant Philips (Philip), Osram (Osram) became the ambition of the leading LED lighting plain if see.

The chairman of Everlight the Ye Yinfu points out that South Korea will soon replace Taiwan to become the leading LED output. If you do not establish its own brand of LED in the next two years, led road light. Taiwan’s LED will become a low-margin OEM model.

The global economic downturn, the LED lighting industry for the industry optimistic about the bright spot in the next few years, led road light, industry, Goldman Sachs issued a report that LED lighting output point of view in 2015 to $ 11 billion, it is estimated that the average compound annual growth rate of over 30% in 2020, will greatly increase penetration to more than 50%.

Countries are to spare no effort to snatch the LED market pie, Epistar pointed out that the 2012 and 2013 LED lighting brand is the most critical moment. U.S. lighting maker LSG in 2012 launched a $ 15 60-watt LED bulbs, but South Korea’s Samsung and LG, led road light, relying on its advantage in the LED industry chain, the third quarter of next year, the first to launch $ 10 60-watt LED bulbs, accelerated the arrival of the sweet spot of traditional light bulbs and LED bulbs, the domestic LED manufacturers Epistar and Everlight anxiety pointed out that,  led road light, if the Samsung leading to snatch an LED lighting leading Taiwan’s LED industry will once again become a low-cost OEM model.

Common classification of the led road light

Common classification of the led road light

According to the light color emitted by LEDs, they can be classified as red, orange green (also can be subdivide into yellow-green, standard green and pure green), blue. In addition, some LEDs contain two or three color chips. These colored LEDs can also be divided into colored transparent, transparent, colored scattering and colorless scattering four types, that is depends on whether scattering diluents are doped into them. The scattering LEDs are not suitable for led high bay.

According to the light-emitting surface characteristics, LEDs can be divided into Circular light, rectangular light, surface light, lateral light, and so on. Normally, diameter of circular light diameter is divided into φ2mm, φ4.4mm, φ5mm, φ8mm, φ10 mm and φ20mm. The distribution of luminous intensity angles can be estimated though half-value angles. And in accordance with distribution of luminous intensity angles, led road light can be classified as follows:

1)      High directivity light: Generally epoxy packing, or a metal reflector cavity, with no scattering diluents. The half-value angle ranges from 5 ° to 20 ° or even smaller. This type of led road light has very high directivity, can be used for local lighting.

2)      Standard light. Usually used for indicator light, its half-value angle could between 20 ° and 45 °.

3)      Scattering light. This is a type of indicator light with a relatively larger visual angle, half-value angle is within 45 ° and 90 ° or even larger. Scattering led road light should be doped by a large amount of scattering diluents to reinforce the scattering effect.
