Abstract
The utility model discloses a heat dissipation type street lamp lamp holder belongs to the street lamp field, has solved the not good problem of street lamp lamp holder heat dispersion in the conventional art. Including the lamp body, be equipped with a plurality of LED chips on the base plate of lamp body inside, the base plate below is provided with back the heat pipe of type, and the liquid working medium of the interior circulation of heat pipe realizes circulating through the micropump that sets up on the heat pipe, the top of heat pipe still is equipped with heat sinkly, be equipped with a plurality of fin first on the heat pipe of heat sink both sides, heat sink top is equipped with the fan. The utility model discloses novel structure, the radiating effect is good, LED install the chip is on the base plate, and micropump cyclic delivery is passed through to the liquid working medium in the heat pipe of base plate below, reaches the heat that the chronozone leaves the chip, street lamp lamp holder long service life.
Description
Technical field
This utility model relates to street lamp technology field, specifically, particularly relates to heat radiation type street lamp lamp holder.
Background technology
Street lamp is the illuminations that daily road surface is conventional, converts the electric energy of luminous energy to less than 30% during LED operation, and all the other electric energy nearly all become heat energy so that it is temperature raises. If junction temperature exceedes maximum allowable temperature, then chip overheating damages. The heat dispersion of existing high-power LED lamp is poor, have impact on the service life of LED lamp. Accordingly, it would be desirable to promote the thermal diffusivity of high-powered LED lamp head unit, extend the service life of light fixture. In prior art, the radiating effect of road lamp cap is low, have impact on the service life of lamp holder.
Summary of the invention
The utility model discloses a kind of heat radiation type street lamp lamp holder, for solving the problem that in conventional art, road lamp cap heat dispersion is bad, it is provided that a kind of road lamp cap with micro-pumping structure, good heat dissipation effect, extend the service life of lamp holder.
This utility model is achieved through the following technical solutions:
A kind of heat radiation type street lamp lamp holder, including lamp housing, substrate within described lamp housing is provided with some LED chips, described substrate is arranged below the heat pipe of hollow, in heat pipe, the liquid working substance of circulation realizes circulation by the Micropump being arranged on heat pipe, being also arranged above of described heat pipe is heat sink, and the heat pipe of described heat sink both sides is provided with some fin first, described heat sink is arranged over fan.
The end of described lamp housing is provided with some fin second.
Compared with prior art, the beneficial effects of the utility model are:
This utility model novel structure, good heat dissipation effect; LED chip is arranged on substrate, and the liquid working substance in heat pipe below substrate, by Micropump circulation conveying, takes away the heat of chip, road lamp cap long service life in time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In Fig. 1: 1, lamp housing; 2, LED chip; 3, substrate; 4, heat pipe; 5, Micropump; 6, heat sink; 7, fan; 8, fin first; 9, fin second.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further illustrated:
A kind of heat radiation type street lamp lamp holder, including lamp housing 1, substrate 3 within described lamp housing 1 is provided with some LED chips 2, described substrate 3 is arranged below the heat pipe 4 of hollow, in heat pipe 4, the liquid working substance of circulation realizes circulation by the Micropump 5 being arranged on heat pipe 4, described heat pipe 4 be also arranged above heat sink 6, the heat pipe of described heat sink 6 both sides is provided with some fin first 8, described heat sink 6 be arranged over fan 7.
The end of described lamp housing 1 is provided with some fin second 9.
As shown in Figure of description 1, a kind of heat radiation type street lamp lamp holder, including lamp housing 1, the end of lamp housing 1 is provided with some fin second 9, and the substrate 3 within lamp housing 1 is provided with multiple LED chip 2, and substrate 3 is arranged below the heat pipe 4 of hollow, in heat pipe 4, the liquid working substance of circulation realizes circulation by the Micropump 5 being arranged on heat pipe 4, heat pipe 4 be also arranged above heat sink 6, the heat pipe of heat sink 6 both sides is provided with fin first 8, heat sink 6 be arranged over fan 7.
The heat of LED chip 2 passes to substrate 3, heat is taken away by the liquid working substance in heat pipe 4 below substrate 3, liquid working substance evaporates, and the working medium after evaporation transfers heat to heat sink 6 and fin first 8 be condensed into liquid again, and Micropump 5 realizes liquid working substance circulation in heat pipe 4; Fin second 9 increases the integral heat sink performance of lamp holder, extends the service life of lamp holder.
This utility model novel structure, good heat dissipation effect; LED chip is arranged on substrate, and the liquid working substance in heat pipe below substrate, by Micropump circulation conveying, takes away the heat of chip, road lamp cap long service life in time.
In sum, it is only preferred embodiment of the present utility model, not it is used for limiting the scope that this utility model is implemented, all equalizations done according to the shape described in this utility model right, structure, feature and spirit change and modify, and all should be included in right of the present utility model.
