Description

A kind of LED street lamp of dust-proof radiating

Technical field

This utility model relates to street lamp field, is specifically related to the LED street lamp of a kind of dust-proof radiating.

Background technology

LED heat radiation industry inner question LED illumination is due to its economize on electricity, environmental protection, long-life, and is acknowledged as next band illumination skill Art.But, LED has the electric energy of 70% more than to be converted into heat energy, it is necessary to heat radiation.Although LED luminescence technology has been developed by leaps and bounds, have Every watt of luminescence reaches the report of 200lm, but LED heat radiation is the problem having a headache very much in LED illumination, has become LED illumination lamp to popularize Radix Clematidis Clarkeanae in road for development；High-power LED street lamp heat dissipation technology.The generally brightness decay of definition LED lamp arrives 30% Time, the temperature tolerance of LED own was poor as its life-span, and its light decay brightness is a process gradually decayed, and this is initial The time of decay, outside the Pass having with the quality of light fixture itself, the most relevant with the Contact Temperature of lamp；Light decay is high-power LED street lamp can not the main cause of long-term work, and heat radiation is improved and strengthened to the important method reducing light decay exactly, if The heat dissipation design of light fixture is not in place, and the junction temperature of LED chip will be too high, will cause chip itself and potting resin penalty, Thus cause reducing and the shortening in life-span of luminous efficiency.The heat dissipation problem being effectively improved LED is to capture high-power illumination light fixture Key.This reason is the simplest, but in LED industry field, heat dissipation problem is the most thorny thing with headache of producer all the time, In order to solve heat radiation and light decay problem, the limit scheming of domestic a lot of enterprises.

The file of Patent No. CN204880048U discloses a kind of LED street lamp radiator, including conducting surface, described biography Being provided with the first stator, the second stator, the 3rd stator and the 4th stator on guide face, described first stator is with described Second stator constitutes the first radiating area, the second stator and the 3rd stator and constitutes the second radiating area, the 3rd stator and Four stators constitute the 3rd radiating area, are all convexly equipped with multiple between described first radiating area, the second radiating area and the 3rd radiating area Radiating fin；This apparatus function is single and DeGrain, and on radiating fin, the outdoor dust deposit of attachment can reduce radiating fin The radiating effect of sheet.

Utility model content

For the deficiencies in the prior art, this utility model provides the LED street lamp of a kind of dust-proof radiating, fairshaped heat radiation Fin can well carry out dust-proof radiating.

For realizing object above, this utility model is achieved by the following technical programs: the LED road of a kind of dust-proof radiating Lamp, including integrated optical source, also includes substrate, housing, radiating fin, control box and cover plate, and described housing is convex shape, described base Plate is positioned at enclosure interior, and described radiating fin is positioned at back side of shell, and described radiating fin quantity is multiple and interval is uniformly distributed At back side of shell, described radiating fin lower end is close to housing and is installed, under the radian of described radiating fin upper end and radiating fin End is consistent；Described control box is positioned at back side of shell, and described cover plate is fixed to control, on box, to set below described control box by screw There are radiating tube, described control box that Street lamps control module is installed.

Preferably, described housing becomes calabash shaped.

Preferably, described integrated optical source quantity is multiple, and described integrated optical source is all arranged on substrate by screw.

Preferably, it is provided with waterproof gasket between described control box and cover plate.

Preferably, described enclosure interior is provided with reflecting coating.

This utility model provides the LED street lamp of a kind of dust-proof radiating, and fairshaped radiating fin can preferably and outward Boundary's air carries out heat exchange, and fairshaped evenly spaced radiating fin can preferably allow natural wind pass, it is to avoid too much Outdoor dust deposit, a small amount of dust can be clean by rain drop erosion, and the housing of epirelief has and is easy to allow the rainwater after rinsing Flow out.
