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.
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.
