Abstract
The utility model relates to an end-cover waterproof ring of a light emitting diode (LED) street lamp, which is arranged between an end cover and a radiator body, and when the end cover and the radiator body are combined, the waterproof ring is positioned between the pedestal of the end cover and the pedestal of the radiator body, and the shape of the waterproof ring is the same with that of a structure at the connecting part of the radiating fin of the end cover and the pedestal of the end cover. The end-cover waterproof ring is respectively arranged between an upper end cover and the radiator body and between a lower end cover and the radiator body, can achieve a better sealing effect between the end cover and the radiator body, prevents an outside water source from entering an LED chip part through an exposed radiator to influence the LED chip part to a certain degree and ensures the working safety of an LED chip.
Description
Technical field
The utility model relates to a kind of LED street lamp, is specifically related to a kind of end cap water proof ring of LED street lamp.
Background technology
Along with the lifting significantly of LED power, LED obtains general application as light source at lighting field.Because advantages such as energy consumption is low, long service life, pollution-free, radiationless heat, LED has guided the lighting source revolution of the 4th generation as the representative of typical low-carbon economy industry, becomes the inexorable trend that replaces the traditional lighting light fixture.But because the optoelectronic transformation efficiency of LED lamp is lower, the actual heat that changed into of most of electric energy, if these heats are dissipated as early as possible effectively, it is very obvious that thing followed fuel factor will become, cause junction temperature to rise, reduce the photon of chip outgoing, colour temperature (luminous flux) quality is descended, it is aging to accelerate chip, shortens device lifetime.Therefore most of LED street lamp all adopts the fin-shaped radiator to dispel the heat, and the upper and lower side of radiator all adopts end cap form and radiator body to be combined into the integral body of radiator, to realize heat sinking function and to protect led chip.And present end cap up and down mainly is by rivet or bolt is direct and radiator body makes up, and can't realize that sealing connects, and for the radiator of exposed setting, appearance causes the impaired situation of led chip because of the radiator water inlet easily.
The utility model content
At above the deficiencies in the prior art, the utility model provides a kind of end cap water proof ring that can realize that end cap and radiator body are tightly connected.
The utility model is achieved through the following technical solutions:
A kind of end cap water proof ring of LED street lamp, described water proof ring are located between end cap and the radiator body, and when end cap and radiator body combination, described water proof ring is between end cap base and radiator body pedestal.
Described water proof ring size is less than the size of end cap base or radiator body pedestal.Described water proof ring shape is identical with end cap base junction structure with the end cap fin.
Described water proof ring is made by silica gel.
The beneficial effects of the utility model are: establishing the end cap water proof ring between end cap and the radiator body up and down, can between end cap and radiator body, reach the better seal effect, stop extraneous water source to a certain extent and entered into the led chip part by the exposed radiator that is provided with it is impacted, guaranteed the work safety of led chip.
Description of drawings
Fig. 1 is a part explosive view of the present utility model.
Fig. 2 is a structural representation of the present utility model.
Among the figure: 1 is end cap; 2 is radiator body; 3 is water proof ring; 4 is end cap base; 5 is the radiator body pedestal; 6 is the end cap fin.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
The utility model provides a kind of end cap water proof ring of LED street lamp, be located between end cap 1 and the radiator body 2, when end cap 1 and radiator body 2 make up, water proof ring 3 is located between end cap base 4 and the radiator body pedestal 5, the size of general water proof ring 3 is less than the size of end cap base 4 or radiator body pedestal 5, and its shape is identical with the structure of end cap base 4 junctions with end cap fin 6.
The utility model is being established end cap water proof ring 3 between end cap 1 and the radiator body 2 up and down, can between end cap 1 and radiator body 2, reach the better seal effect, stop extraneous water source to a certain extent and entered into the led chip part by the exposed radiator that is provided with it is impacted, guaranteed the work safety of led chip.
Salable materials such as water proof ring 3 general employing silica gel are made.
Claims (4)
1. the end cap water proof ring of a LED street lamp is characterized in that described water proof ring is located between end cap and the radiator body, and when end cap and radiator body combination, described water proof ring is between end cap base and radiator body pedestal.
