The invention provides the LED street lamp in which the heat radiator, the heat tube and the LED device can be produced into standard modules and the LED street lamp is suitable for different specifications in the same width series.
Description
Technical field
The present invention relates to the electrical lighting field, relate to a kind of straight formula LED street lamp that looses specifically.
Background technology
Along with continually developing of high-power LED chip; The caloric value of led chip also improves and increases fast along with luminosity, especially in large power road lamp, for satisfying the optics requirement of street lamp; Must be in the road lamp inner chamber many high-power LED chips of intensive layout; And the necessary airtight waterproof of road lamp, the heat dissipation problem that this just requires to solve led chip can guarantee LED street lamp operate as normal.In the prior art, be with the road lamp housing as radiating element, with the circuit board that is welded with led chip directly and the street lamp housing combine, to reach the heat radiation purpose.This radiator structure exist many defectives, the area of radiating effect and lamp housing is relevant, but streetlamp housing is can not volume excessive, one wastes the lamp housing material, increases manufacturing cost, two come lamp housing excessive, its weight will influence to be used and installs.
Summary of the invention
For addressing the above problem, the invention provides a kind of brand-new LED street lamp, the heat that produces when led chip is worked conducts on the individual heat sinks part through heat conductor spare and dispels the heat.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is:
The LED street lamp comprises radiator, heat pipe, LED device, lamp housing, it is characterized in that: two radiators are separately fixed at the left surface and the right flank of lamp housing.
The LED street lamp; It is characterized in that: radiator comprises radiating fin, heat-radiating substrate, heat pipe, and several radiating fins are arranged on the heat-radiating substrate front, and the heat-radiating substrate back side offers the tube seat that is consistent with the heat pipe diameter; Heat pipe is placed in the tube seat at the heat-radiating substrate back side, and fixes with attachment fastener.
The LED street lamp; It is characterized in that: the LED device comprises led chip, circuit board, LED device substrate, lampshade; Led chip is welded on the circuit board; Circuit board is fixed on fixed screw on the front of LED device substrate, and lampshade is buckled on the LED device substrate and with fixed screw and fixes, and the back side of LED device substrate offers the tube seat that is consistent with the heat pipe diameter.
The LED street lamp is characterized in that: the radiating fin of radiator, heat-radiating substrate, LED device substrate are that Heat Conduction Material is processed,
The LED street lamp is characterized in that: the U type that is shaped as of heat pipe, a LED street lamp can adopt one or more U type heat pipe
The LED street lamp is characterized in that: two upright end of U type heat pipe are placed in the tube seat of the heat-radiating substrate back side, and the bottom of U type heat pipe is placed in the tube seat at the LED device substrate back side, and fixes with attachment fastener.
The LED street lamp that the present invention relates to, radiator, heat pipe and LED device can be processed the module of standard, are applicable to the product of different size in the same width series.
