The utility model solves the problem of difficult radiation of a current high power LED, and has the advantages of excellent radiation effect, long service life, high light-emitting efficiency, large illumination range and convenient LED change.
Description
Technical field
The utility model relates to the high-powered LED lamp technical field, especially a kind of high-power LED street lamp.
Background technology
General street lamp, all based on bulb, but the shortcoming of bulb is exactly power consumption and life-span weak point.In recent years, the power tense phenomenon appears in the increasing province of China, particularly summer the continuous high temperature sweltering hot weather, the easier power supply shortage that causes, for this reason, governments at all levels and relevant departments take all measures to alleviate the power supply shortage situation.LED has characteristics such as far away, the poly-optical activity of high luminosity, projection distance is good, meets the application requirements of street lighting fully, and especially it has the low advantage of power consumption, makes the LED replacement bulb be applied to become on the street lamp developing direction of novel energy-saving road lamp from now on.But, low-power LED must concentrate many low-power LED monomers just can reach designing requirement as street lighting, and is complicated unusually thereby the shortcoming of bringing is exactly a circuit, it is not smooth to dispel the heat, for electric current, voltage relationship between each LED monomer of balance must design complicated power supply circuits.Comparatively speaking, the power of great power LED monomer is much larger than the summation of the single LED of small-power, but can produce bigger heat during great power LED work, chip power is big more, the heat that produces is many more, the heat that produces distributes timely as can not get, the temperature rise meeting causes the LED light decay serious, even lost efficacy, the research report is arranged, LED becomes power exponent to concern service life with operating temperature, for example, 25 ℃ of work down, LED can reach 100,000 hours service life, and 90 ℃ of work down, be reduced to service life 7000 hours, in actual the use, can only reduce the heat radiation difficult problem that supply current solves great power LED usually, can cause the luminosity of LED not reach instructions for use so again.Heat dissipation problem is the key factor that makes the great power LED efficient operation and improve device lifetime, is that great power LED is applied to street lamp problem anxious to be solved.
Summary of the invention
The technical problems to be solved in the utility model is: solve the difficult problem of heat radiation of existing great power LED, provide a kind of good heat dissipation effect, luminous efficiency height, the high-power LED street lamp of long service life.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of high-power LED street lamp, has lamp body, lamp body is made up of integrated heat-radiating substrate and fin, heat-radiating substrate is provided with at least one lamp socket, great power LED is housed in the lamp socket, between LED and lamp socket heat conductive silica gel is arranged, the LED below is provided with light-passing board, light-passing board and lamp socket sealing and fixing.
Described fin is a wave shaped radiator, to increase area of dissipation, further improves radiating effect.
Described lamp socket and heat-radiating substrate are structure as a whole, and to reduce the thickness of heat-radiating substrate, further improve radiating effect.
For ease of changing LED, to avoid causing the whole LED street lamp to be scrapped because of LED loses efficacy, described heat-radiating substrate is provided with the lamp socket fixing threaded hole, and lamp socket is threaded with heat-radiating substrate.
For improving the range of exposures of street lamp, described light-passing board is convex lens.
The beneficial effects of the utility model are, high-power LED street lamp good heat dissipation effect of the present utility model, and long service life, the luminous efficiency height, range of exposures is big, and LED changes convenient.
