Harbin street lamp lighting manufacturer how to solve the problem of LED street light, heat dissipation

Solar street lamp brightness requirements, high calorific value is big, if you can directly lead to LED aging fast, stable performance, so how to solve the problem of LED street lamp radiator? For use in the outdoor road lamps and lanterns should have certain levels of dust waterproof work



solar street lamp brightness requirements, high calorific value is big, if you can directly lead to LED aging fast, stable performance, so how to solve the LED street lamp LED street lamp is made of street lamp, LED lamps and lanterns with high efficiency, safety, energy saving, environmental protection, long service life, fast response speed, high color rendering index of unique advantages, the city lighting energy saving is of great significance. 】 The heat dissipation problem? For use in the outdoor road lamps and lanterns should have certain levels of dust waterproof function ( IP) , a good IP protection tends to hamper the LED heat dissipation. Solve this contradiction, but have to solve the two problems are the road lighting design should pay attention to an important aspect, in this respect is also apply LED to domestic road lamps and lanterns is unqualified and most of the unreasonable situation. In the domestic use of unqualified and unreasonable situation are basic: ( 1) For the LED street lamp used the radiator, but LED connecting terminals and radiator design cannot achieve IP45 and above level, can meet GB7000. 5 / IEC6598 - 2 - 3 standard requirements. ( 2) Using common road lamps shell, using matrix LED inside the lamps and lanterns is a smooth surface, although this kind of design can meet the IP test, but not because of lamps and lanterns ventilation can cause at work, the temperature of the inner cavity of lamps and lanterns will rise to 50 ℃ ~ 80 ℃, under the working condition of the high, LED luminous efficiency is impossible high, the service life of the LED will also be discounted at the same time, in fact there is an obvious unreasonable situation. ( 3) In the lamps and lanterns, the instrument will be used to LED and fan cooling radiator, the inlet design in the lower part of lamps and lanterns, in order to avoid the rain the diffuser design next shot around the LED light source, which can effectively avoid the rain in. Additional radiator and LED ( Light source cavity) Not, within the cavity is with the design, such as doing good, according to the requirements of the IP test of lamps and lanterns, can pass. This scheme not only can solve the problem of LED the heat dissipation, and at the same time meet the requirements of the IP rating. But this seems to be a good design, in fact, there is an obvious unreasonable situation, because most of the roads in our country the use of lamps and lanterns, the dust in the air volume is larger, and sometimes will achieve a lot, Such as dust) , this kind of lamps and lanterns under the condition of general use after a period of time ( About three months to half a year) , its internal dust will fill the gaps in the radiator, the radiator effect, finally still can make the LED significantly shorten the service life by working temperature is too high, the lack of this scheme is not lasting good to use.
