Abstract
The utility model provides a light emitting diode (LED) street lamp radiator, which is arranged at the back of an LED chip. The radiator comprises a base and a radiating fin arranged on the base, wherein the radiating fin is provided with waved grains. The radiating fin can greatly increase the radiation area, the radiating fin is provided with the waved grains, and then the radiation area is increased again under the condition that the height of the radiating fin is not changed. The utility model effectively solves the dissipation of heat of an LED lamp in a mode of enlarging the radiation area, ensures color temperature quality, delays the aging of the chip, and ensures the service life of the LED lamp.
Description
Technical field
The utility model relates to a kind of LED street lamp, is specifically related to a kind of radiator 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, and causes junction temperature to rise, and reduces the photon of chip outgoing, colour temperature (luminous flux) quality is descended, it is aging to accelerate chip, shortens device lifetime, therefore solve heat dissipation problem for night long-time in running order LED street lamp seem particularly important.
The utility model content
At above the deficiencies in the prior art, the utility model provides a kind of simple in structure, LED streetlamp with favorable radiating effect radiator.
The utility model is achieved through the following technical solutions:
A kind of LED street lamp heat radiator, described radiator is arranged at the led chip back side, and described radiator comprises pedestal, and described pedestal lower surface directly directly contacts in the led chip back side, and described pedestal is provided with fin.
Described fin is provided with the wave lines.
The height of described fin is inwardly raise gradually by the pedestal outer rim.
Described fin is located at the pedestal both sides; The pedestal middle part is the structure groove.
The utility model beneficial effect is: being provided with of fin can greatly increase area of dissipation, and establishes the wave lines on fin, and promptly being implemented under the immovable situation of fin height has increased area of dissipation once more.The utility model has been guaranteed the colour temperature quality by the dissipation that the mode that enlarges area of dissipation has solved LED lamp heat effectively, has delayed the chip degree of aging, has guaranteed the service life of LED lamp.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 is pedestal; 2 is fin; 3 is the wave lines; 4 is the structure groove.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
The utility model provides a kind of LED street lamp heat radiator, and the installation site of radiator is at the back side of led chip, and heat spreader structures comprises pedestal 1 and fin 2.The lower surface of pedestal 1 directly directly contacts in the led chip back side, and the upper surface of pedestal 1 is provided with fin 2, and this is provided with the area of dissipation that can greatly increase radiator.The utility model is also considered wave lines 3 is set on fin 2, and can be implemented in like this under the immovable situation of fin height has increased area of dissipation once more.Fin 2 is arranged at pedestal 1 both sides, and the height of fin 2 is inwardly raise gradually by pedestal 1 outer rim, but pedestal 1 middle part is not provided with fin 2, or is provided with highly minimum fin 2, is structure groove 4 herein, is used to install the fixed mount of external power supply or LED street lamp.
The utility model has been guaranteed colour temperature (luminous flux) quality by the dissipation that the mode that enlarges area of dissipation has solved LED lamp heat effectively, has delayed the chip degree of aging, has guaranteed the service life of LED lamp.
