Description

Liquid-cooling heat radiation LED street lamp
Technical field
This utility model belongs to street lamp field, relates to LED street lamp, especially a kind of liquid-cooling heat radiation LED street lamp.
Background technology
It is known that LED photovoltaic conversion efficiency restricts 15%~20%, remaining electric energy almost all is converted into heat Can, therefore when LED product works, it will produce substantial amounts of heat.When multiple LED dense arrangement composition street lamp, heat Building-up effect is even more serious.If not shed as early as possible by this heat, thing followed heat effect will be apparent upon.This will cause core Sheet internal heat is assembled, and causes emission wavelength drift, light extraction efficiency decline, fluorescent material accelerated ageing and shortening in service life etc. Series of problems.
Utility model content
In place of the purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of liquid-cooling heat radiation LED street lamp.
This utility model solves technical problem and be the technical scheme is that
A kind of liquid-cooling heat radiation LED street lamp, including housing, lampshade, light guide plate, LED lamp bead, circuit board, in the front end of housing Face is laterally shaped with rectangular through-hole, in through hole be embedded in rectangular frame, rectangular frame end face be embedded in lampshade, in the lower end of lampshade Light guide plate is pasted in face, and uniform interval setting-in LED lamp bead in light guide plate, LED lamp bead connects circuit board, and circuit board is inlaid in rectangle The bottom of framework, is filled with coolant media in housing, and the outer wall uniform intervals at housing is shaped with multiple radiating fin.
And, described coolant media is transformer oil.
And, described housing is metal shell.
Advantage of the present utility model and good effect be:
This street lamp utilizes the feature such as transformer oil insulation, big, the good heat conductivity of specific heat capacity, lowers the temperature LED lamp bead, from And improve the radiating efficiency of LED.
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.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings and by specific embodiment, and following example are simply retouched The property stated, be not determinate, it is impossible to limit protection domain of the present utility model with this.
A kind of liquid-cooling heat radiation LED street lamp, including housing 1, lampshade 3, light guide plate 5, LED lamp bead 4, circuit board 6, at housing Front end face is laterally shaped with rectangular through-hole, in through hole be embedded in rectangular frame 2, rectangular frame end face be embedded in lampshade, at lampshade Lower surface paste light guide plate, in light guide plate uniform interval setting-in LED lamp bead, LED lamp bead connect circuit board, circuit board be embedded in Bottom at rectangular frame.Coolant media 7 it is filled with, for the heat radiation of LED, at the outer wall uniform intervals of housing in housing It is shaped with multiple radiating fin 8.
Described coolant media is transformer oil or other insulating radiation oil.
Described housing is metal shell.
Above-described is only preferred implementation of the present utility model, it is noted that for the ordinary skill of this area For personnel, on the premise of conceiving without departing from utility model, it is also possible to making some deformation and improvement, these broadly fall into this reality With novel protection domain.
