Description
Technical field
This utility model belongs to street lamp field, relates to LED street lamp, a kind of LED street lamp dispelled the heat by coolant.
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 LED dispelled the heat by coolant
Street lamp.
This utility model solves technical problem and be the technical scheme is that
A kind of LED street lamp dispelled the heat by coolant, including housing, lampshade, light guide plate, LED lamp bead, circuit board, at housing
Front end face be laterally shaped with rectangular through-hole, in through hole be embedded in rectangular frame, 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
In the bottom of rectangular frame, in housing, it is filled with coolant media, circulating pump and heat exchanger is installed in lamp stand, by circulation
Pipeline is connected with coolant media.
And, described coolant media is transformer oil.
And, described housing is metal shell.
And, described heat exchanger is the adjustable circulation radiator of temperature control.
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 LED street lamp dispelled the heat by coolant, including housing 1, lampshade 3, light guide plate 5, LED lamp bead 4, circuit board 6,
The front end face of housing is laterally shaped with rectangular through-hole, in through hole be embedded in rectangular frame 2, rectangular frame end face be embedded in lampshade,
Paste light guide plate in the lower surface of lampshade, uniform interval setting-in LED lamp bead in light guide plate, LED lamp bead connects circuit board, circuit
Plate is inlaid in the bottom of rectangular frame.Coolant media 7 it is filled with, for the heat radiation of LED in housing.Install in lamp stand and follow
Ring pump 9 and heat exchanger 10, be connected with coolant media by circulation line 8, make coolant media formed one circulation, cooling return
Road.
Described coolant media is transformer oil or other insulating radiation oil.
Described housing is metal shell.
Described heat exchanger is the adjustable circulation radiator of temperature control.
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.
