Second generation LED street lamp "flying fish" come out

Flying fish two generation LED street lamp design Description: through a large area of radiator design to solve the problem of heat dissipation, according to high power LED particles for its shape design. About LED internal packaging, heat dissipation, road lighting efficiency, enterprises are constantly improve and mature, with its internal technical breakthrough in the development of LED street lamp design will form a new outdoor lamp design direction.

LED lighting is the most popular focus in the lighting industry, because of its energy saving, long service life, safety and environmental protection, by the government departments and industry. Now a lot of LED street lamp project has been a pilot project, such as Shenzhen, Shanghai, Nanjing, Chongqing, Dalian, Guangzhou, Hangzhou, etc..

With the development of semiconductor technology, high brightness light-emitting diode manufacturing technology breakthrough, the country hopes to promote and gradually replace the light source, high luminous efficiency low light effect light. Now do a lot of street, the main problem is that the technology is not mature, but there are a lot of companies came before the current implementation problems, energy-saving lighting products in the outstanding performance, low level of technology, product quality is not stable, short service life, the larger the gap with international standards; generally small scale, backward technology enterprises; lighting product structure is not reasonable, the degree of coordinated development of raw materials and accessories, can not adapt to the requirements of the development of industrialization; lighting equipment market confusion, low price, low quality, fake and shoddy products, a large impact on the market. Therefore, the development of high efficiency, energy saving, high quality LED lighting products, is the obligation of every R & D and production enterprises.

Ma comprehensive analysis of the above, the design of the LED street lamp has a further understanding, the first is the shape design, this led "flying fish" two generations, reflects a new direction of development.

Novel LED street lamp

The problem of heat dissipation is the biggest difficulty in the application of high power LED in the lighting. At present, there are several forms of heat dissipation of high power LED. Natural heat convection using natural convection heat conduction and heat radiation, the installation of forced cooling fan mainly uses forced air convection to achieve heat dissipation, heat pipe cooling of course, the main use of heat pipe as a heat sink. The lowest natural thermal cost, reliable structure, easy to be waterproof, but the structure design of the lamp body itself requires high; installing the fan forced cooling heat quickly, but the high cost, high noise, short service life, difficult to do waterproof fan often need to replace the heat pipe cooling; no moving parts, the system is stable, but the cost is high, too not pretty. Therefore, in the design of the structure, we must consider many factors.

Driving part: the core of LED street lamp is the design of switch power supply and the structure of constant current drive. In this regard, but also through the horse with Taiwan enterprises have a good communication. At present, the widely used LED street lamp switching power supply generally has a rectifying filter circuit, a regulating circuit, a sampling circuit, an overcurrent protection circuit and a DC constant current output circuit.

Many enterprises in the development process, all mentioned that does not need to design the light distribution, in fact, this is a kind of irresponsible for the development of lamps, are simply not willing to invest in the immediate interests, the design is too large. However, as a professional lighting design company, in the design of each lamp above, we are going to consider, and strive to give the design of the enterprise is the best, which is also the obligation of the horse.
