Abstract
The utility model discloses an LED street lamp radiator comprising radiating fins, wherein more than one wind wheel blades are arranged above the radiating fins as well as on an LED street lamp body or directly arranged on the radiating fins; the wind wheel blades rotate under the driving of natural air to generate wind power for blowing to the radiating fins to forcibly exchange heat. The LED street lamp radiator utilizes the natural air energy to carry out forcible heat exchange on the radiating fins of the LED; due to no need of additional power supply to supply power for a radiating fan, the LED street lamp radiator has energy conservation and environmental protection, simple structure, safe and reliable running and low fault rate without electrical elements such as a motor and the like, and can effectively prolong the service life of a light source module of the LED street lamp.
Description
Technical field
The utility model relates to the LED lighting field, is specifically related to a kind of LED heat radiating device of road lamp.
Background technology
The Led illumination is environment-friendly energy-saving, green illumination high-tech industry, and the led light source has the characteristics of environmental protection, efficient energy-saving.As everyone knows, the service life and the radiating effect of led light source are closely related, and led fluorescent tube core junction temperature is too high, can cause the compound semiconductor materials mis-behave.
Present stage, most of led street lamps all are by manufacturing and encapsulation, and the led chip heat is delivered to base plate for packaging fast, and then are dispelled the heat by the shell radiating fin of led light source module.This mode, because the efficiently radiates heat area of light source substrate or light source module shell radiating fin is big inadequately, again or since the residing environment of led light source road lamp be not easy to ventilate, cause the heat exchange of shell radiating fin and its surrounding air abundant inadequately, cause heat to be assembled at the outer shell face, make that the heat radiation situation on led lamp surface is undesirable, thereby cause the led die temperature of light source inside too high, cause losing efficacy thereby cause the light source module life-span to reduce.
The utility model content
Technical problem to be solved in the utility model provides a kind of LED heat radiating device of road lamp of simple and reliable for structure, energy-conserving and environment-protective.
The technical scheme that the utility model adopted is: the LED heat radiating device of road lamp, comprise fin, described fin top is provided with an above air vane, described air vane is installed on the LED road lamp body or directly is installed on the fin, and described air vane drives the backspin living wind-force of changing the line of production at natural wind and blows to fin and force heat exchange.
In order to store the mechanical energy that wind energy converts to, also be provided with accumulating mechanism on the described air vane rotating shaft, accumulating mechanism is preferably wind spring, when wind-force Big Pinwheel blade rotation is very fast, can be that the elastic potential energy of wind spring still can make the air vane rotation that fin is forced heat exchange when calm like this with wind energy transformation.
Based on same inventive principle, the another kind of technical scheme that the utility model adopted is: the LED heat radiating device of road lamp, comprise fin, install on the described LED street lamp or on the fin and be provided with an above air vane, described fin top is provided with an above fan, described air vane rotates by the transmission mechanism drive fan, transmission mechanism is preferably gear drive or belt pulley transmission, can certainly adopt other general mechanical drive modes, fan rotates the generation wind and forces heat exchange to fin, described fan is contained on the LED road lamp body or directly is installed on the fin, this technical scheme can be used and make air vane select best wind-engaging position to install, air vane can do more simultaneously, and wind-force is more powerful when driving the fan rotation, and radiating effect is better.
Equally, in order to store the mechanical energy that wind energy converts to, also be provided with accumulating mechanism on the described air vane rotating shaft, accumulating mechanism is preferably wind spring, like this when wind-force Big Pinwheel blade rotation is very fast, the elastic potential energy that can be wind spring with wind energy transformation still can make air vane rotate the drive fan rotation when calm again, so that fin is forced heat exchange.
The beneficial effects of the utility model are: the utility model utilizes the natural wind wind energy that the fin of LED is forced heat exchange, owing to need not additional power supply be powered by radiator fan, energy-conserving and environment-protective, simple in structure, do not need electrical equipments such as motor, safe and reliable to operation, fault rate is low, can effectively prolong the service life of led road-light light-source module.
