Abstract
The utility model belongs to the technical field of the street lamp, concretely relates to solar light -emitting diode (LED) road lamp holder. Which comprises the components of a lampshade, install heat sink base plate in the lamp shade, the bottom surface facing of heat sink base plate is equipped with LED chip array, the surface of heat sink base plate is provided with a plurality of perpendicular type radiating fin, be equipped with a steam chamber in the heat sink base plate, the steam intracavity is filled with liquid working medium, one mao of mesh grid is placed to the steam intracavity, the top symmetry of heat sink base plate is provided with the seal groove. The beneficial effects of the utility model are that: the radiating effect is good, effectively reduces the change of LED chip array photoelectric characteristic, reduces its light decay, and then makes the life of LED lamp prolong greatly, has reduced use cost, does benefit to and extensively uses widely.
Description
Technical field
This utility model belongs to street lamp technology field, is specifically related to a kind of solar LED street lamp lamp holder.
Background technology
LED is a kind of electric energy-light energy converter part, in transformation process, major part energy is converted to heat energy, during work, device temperature is up to more than 120 °, the photoelectric characteristic making LED chip is produced serious change by high temperature, and light decay is serious, and then makes play greatly shortening the service life of LED, the LED lamp holder radiating effect of prior art does not reaches above-mentioned requirements, accordingly, it would be desirable to a kind of novel solar LED street lamp lamp holder, effectively solve above-mentioned situation.
Utility model content
The deficiency existed for prior art, this utility model provides a kind of good heat dissipation effect, length in service life and effectively reduces the solar LED street lamp lamp holder of light decay.
This utility model is achieved through the following technical solutions:
A kind of solar LED street lamp lamp holder, including lampshade, in described lampshade, heat sink substrate is installed, it is pasted with LED chip array on the bottom surface of described heat sink substrate, the surface configuration of described heat sink substrate has multiple vertical-type radiating fin, is provided with a vapor chamber, is filled with liquid working substance in described vapor chamber in described heat sink substrate, placing a capillary network in described vapor chamber, the top of described heat sink substrate is symmetrically arranged with seal groove.
Further, it is provided with sealing ring in described seal groove.
Compared with prior art, the beneficial effects of the utility model are: good heat dissipation effect, effectively reduce the change of LED chip array photoelectric characteristic, reduce its light decay, and then the service life of LED is greatly prolonged, reduce use cost, be beneficial to be widely popularized use.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present utility model.
In accompanying drawing: 1. lampshade；2. heat sink substrate；3.LED chip array；4. radiating fin；5. vapor chamber；6. liquid working substance；7. capillary network；8. seal groove.
Detailed description of the invention
A kind of solar LED street lamp lamp holder, including lampshade 1, heat sink substrate 2 is installed in lampshade 1, LED chip array 3 it is pasted with on the bottom surface of heat sink substrate 2, the surface configuration of heat sink substrate 2 has multiple vertical-type radiating fin 4, is provided with a vapor chamber 5, is filled with liquid working substance 6 in vapor chamber 5 in heat sink substrate 4, placing a capillary network 7 in vapor chamber 5, the top of heat sink substrate 2 is symmetrically arranged with seal groove 8.
Further, in seal groove 8, it is provided with sealing ring, utilizes Outer screw heat sink substrate and radiating fin well to be sealed.
Specific works principle is: chip array distributes heat in the course of the work, the liquid working substance easily undergone phase transition in heating heat sink substrate, make it evaporate or vaporization zone walks heat, it is connected to the heat sink substrate of radiating fin along with the rising of gas runs into upper strata, because of the relatively low gas liquefaction heat release of its temperature, again accumulate in the understructure of heat sink substrate after gas liquefaction, effect due to capillary network, liquid can be good at scattering, and the heat of uniform pickup heat sink substrate lower floor becomes gas mutually and carries out circulation again.
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 impartial changes done according to shape, structure, feature and the spirit described in this utility model right and modification, all should be included in right of the present utility model.
Claims (2)
1. a solar LED street lamp lamp holder, it is characterized in that: include lampshade, in described lampshade, heat sink substrate is installed, it is pasted with LED chip array on the bottom surface of described heat sink substrate, the surface configuration of described heat sink substrate has multiple vertical-type radiating fin, is provided with a vapor chamber, is filled with liquid working substance in described vapor chamber in described heat sink substrate, placing a capillary network in described vapor chamber, the top of described heat sink substrate is symmetrically arranged with seal groove.
A kind of solar LED street lamp lamp holder the most according to claim 1, it is characterised in that: it is provided with sealing ring in described seal groove.
