Description

A kind of LED road lamp cap
[technical field]
The utility model relates to a kind of road lamp cap, particularly relates to a kind of LED road lamp cap.
[background technology]
LED is a kind of energy-efficient light source, and has the advantage of long working life, investigates its use cost and energy efficiency indexes all significantly is better than various conventional light source according to cycle life-cycle.But because LED itself is a semiconductor devices, operating temperature there is certain requirement, can only be operated in certain temperature range.High temperature can influence its working life greatly, so rapid dissipation the away of heat that how LED is produced in luminescence process is to guarantee that it can reach the key factor in normal service life.
Along with progress of science and technology, light emitting diode (LED) has obtained significant progress, the appearing as led light source and can get in being extensive use of and lay a good foundation of white light LEDs and great power LED, add the good characteristic of LED low-consumption high-efficiency, it has been adopted to replace the big incandescent lamp of traditional energy loss by all trades and professions and has been used for illumination.Street lighting also began to adopt LED as light source gradually in the last few years, but was limited to monomer LED luminance shortage to satisfy the demand of street lighting, and high-power LED street lamp often all adopts the lighting system of LED matrix fit lens.Yet, though LED is as a kind of new type light source, it is the process that is changed into luminous energy and heat energy by electric energy, the light energy use efficiency of present stage LED is generally 20%, and 80% consuming as heat energy arranged, therefore the heating problem of LED can not be ignored, and especially can't neglect especially as the heating problem of a large amount of great power LED matrixes that are equipped with.At present all can solve heat dissipation problem in the great power LED matrix by disposing large-scale fin, yet problem is following, the general power of LED street lamp constantly rises on the one hand, also do bigger and bigger for increasing its corresponding fin of area of dissipation, many extra cost expenses have been caused, the weight of light fixture also can't be accepted, secondly also need in use to be installed in the special-purpose lampshade owing to high-power LED street lamp, sometimes or even be placed in one relatively in the cover body of sealing, because heat can't form convection current with outside air in the cover body of sealing, can only carry out heat transmission seldom by the air of simple radiation and big thermal resistance, even the heat that big again fin also can't send LED is so taken away, finally cause heat to be hoarded on fin, radiating effect is had a greatly reduced quality, thereby influence the life-span of whole light fixture.
[utility model content]
