Abstract
The utility model relates to a kind of LED street lamp of perfect heat-dissipating, comprise lamp bracket, lamp housing, armorplate glass, light guide plate, LED lamp bead and circuit board, it is characterized in that: on lamp bracket, be shaped with a rectangular through-hole, setting-in lamp housing in through hole, at the end face setting-in armorplate glass of lamp housing, light guide plate is pasted in the lower surface of armorplate glass, uniform interval setting-in LED lamp bead in light guide plate, a gripper shoe is fixedly mounted with in the bottom of lamp housing, circuit board is fixedly mounted with in the upper surface of gripper shoe, described lamp pearl is all connected with circuit board, thermal column is shaped with at uniform interval, the lower surface of gripper shoe.This road lamp radiating structure is reasonable in design, takes full advantage of space, increases area of dissipation, improves radiating efficiency.
Description
Technical field
The utility model belongs to lighting field, relates to street lamp, especially a kind of LED street lamp of perfect heat-dissipating.
Background technology
As everyone knows, the restriction of LED photovoltaic conversion efficiency is 15% ~ 20%, and remaining electric energy almost all converts heat energy to, therefore when LED product works, will produce a large amount of heats.When multiple LED dense arrangement composition street lamp, the building-up effect of heat is even more serious.If do not shed as early as possible by this heat, thing followed fuel factor will clearly.This will cause chip internal heat accumulation, causes the series of problems such as emission wavelength drift, light extraction efficiency decline, fluorescent material accelerated ageing and shortening in service life.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides the LED street lamp of the perfect heat-dissipating that a kind of perfect heat-dissipating, radiating efficiency are high.
The technical scheme that the utility model technical solution problem adopts is:
A kind of LED street lamp of perfect heat-dissipating, comprise lamp bracket, lamp housing, armorplate glass, light guide plate, LED lamp bead and circuit board, it is characterized in that: on lamp bracket, be shaped with a rectangular through-hole, setting-in lamp housing in through hole, at the end face setting-in armorplate glass of lamp housing, light guide plate is pasted in the lower surface of armorplate glass, uniform interval setting-in LED lamp bead in light guide plate, a gripper shoe is fixedly mounted with in the bottom of lamp housing, circuit board is fixedly mounted with in the upper surface of gripper shoe, described lamp pearl is all connected with circuit board, is shaped with thermal column at uniform interval, the lower surface of gripper shoe.
And, be shaped with annulus projection at the uniform interval of the axis of thermal column.
Advantage of the present utility model and good effect are:
1, this street lamp is shaped with thermal column at uniform interval, the lower surface of gripper shoe, and this heat radiation structure design is reasonable, takes full advantage of space, increases area of dissipation, improve radiating efficiency.
2, this street lamp is shaped with annulus projection at the uniform interval of the axis of thermal column, further increase area of dissipation, the heat that LED is discharged is discharged outside lamp fast, fully, avoid internal heat to assemble, cause the series of problems such as emission wavelength drift, light extraction efficiency decline, fluorescent material accelerated ageing and shortening in service life.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to cross section enlarged drawing;
Fig. 3 is the B portion schematic enlarged-scale view of Fig. 2.
Detailed description of the invention
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of LED street lamp of perfect heat-dissipating, comprise lamp bracket 1, lamp housing 2, armorplate glass 3, light guide plate 5, LED lamp bead 4 and circuit board 6, lamp bracket is shaped with a rectangular through-hole, setting-in lamp housing in through hole, at the end face setting-in armorplate glass of lamp housing, pastes light guide plate in the lower surface of armorplate glass, uniform interval setting-in LED lamp bead in light guide plate, be fixedly mounted with a gripper shoe 7 in the bottom of lamp housing, be fixedly mounted with circuit board in the upper surface of gripper shoe, described lamp pearl is all connected with circuit board.Being shaped with thermal column 8 at uniform interval, the lower surface of gripper shoe, in order to increase the area of dissipation of thermal column, being shaped with annulus projection 9 at the uniform interval of the axis of thermal column.
Above-described is only preferred embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from utility model design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
Claims (2)
1. the LED street lamp of a perfect heat-dissipating, comprise lamp bracket, lamp housing, armorplate glass, light guide plate, LED lamp bead and circuit board, it is characterized in that: on lamp bracket, be shaped with a rectangular through-hole, setting-in lamp housing in through hole, at the end face setting-in armorplate glass of lamp housing, light guide plate is pasted in the lower surface of armorplate glass, uniform interval setting-in LED lamp bead in light guide plate, a gripper shoe is fixedly mounted with in the bottom of lamp housing, circuit board is fixedly mounted with in the upper surface of gripper shoe, described lamp pearl is all connected with circuit board, is shaped with thermal column at uniform interval, the lower surface of gripper shoe.
