Abstract
The invention belongs to the technical field of street lamps and particularly provides an LED street lamp. The LED street lamp comprises a lamp holder, a light diffusion cover and multiple LED lamp beads arranged on the bottom face of the lamp holder, wherein an opening of the light diffusion cover is downward, the light diffusion cover is connected around the lamp holder and is provided with an interlayer, a fan is arranged on the light diffusion cover and is connected with an input circuit of the lamp holder through a lead arranged in the interlayer of the light diffusion cover, and multiple cooling fins or cooling columns are arranged on the outer surface of the light diffusion cover and the top face of the lamp holder. Dust removal and temperature reduction are conducted on the LED street lamp by using the fan, heat dissipation performance is good, and the service life of the LED street lamp is prolonged.
Description
Technical field
The invention belongs to street lamp technology field, be specifically related to a kind of LED street lamp.
Background technology
LED makes the use of LED more and more extensive due to factors such as its luminous efficiency are high, power consumption is little, long service life, security reliability are strong, existing lighting will be replaced gradually, certainly be also used on the street lamp of road lighting, but, existing LED street lamp causes heat radiation bad poor with illuminance due to dust deposit, and the dust how clearing up street lamp is strengthened dispelling the heat simultaneously and become the concern of people to LED street lamp.
Summary of the invention
The object of the invention is to solve existing LED street lamp cannot automatic dust removing and bad problem of dispelling the heat.
For reaching above-mentioned purpose, the invention provides a kind of LED street lamp, comprise lamp socket, diffuser and multiple LED lamp bead being arranged on lamp socket bottom surface, diffuser is opening down, be connected to around lamp socket, diffuser is provided with interlayer, and diffuser is provided with fan, fan is connected with the input circuit of lamp socket by being arranged on the wire in diffuser interlayer, and diffuser outer surface and lamp socket end face are provided with multiple fin or thermal column.
Said fans installation by adhering is on diffuser inwall, and fan is towards lamp socket bottom surface.
Said fans is multiple, is evenly distributed in diffuser circumferential inner surface.
Advantage of the present invention is: compared with prior art, this LED street lamp, comprise lamp socket, diffuser and multiple LED lamp bead being arranged on lamp socket bottom surface, diffuser is opening down, be connected to around lamp socket, diffuser is provided with interlayer, diffuser is provided with fan, fan is connected with the input circuit of lamp socket by being arranged on the wire in diffuser interlayer, diffuser outer surface and lamp socket end face are provided with multiple fin or thermal column, this LED street lamp, use fan to carry out dedusting cooling to LED, perfect heat-dissipating, extends the service life of LED street lamp.
Accompanying drawing explanation
Fig. 1 is the structural representation of LED street lamp.
Description of reference numerals: 1, lamp socket; 2, LED lamp bead; 3, diffuser; 4 fans; 5, fin or thermal column.
Detailed description of the invention
Embodiment one
As shown in Figure 1, present embodiments provide a kind of LED street lamp, comprise lamp socket 1, diffuser 3 and multiple LED lamp bead 2 being arranged on lamp socket 1 bottom surface, diffuser 3 is opening down, be connected to around lamp socket 1, diffuser 3 is provided with interlayer, and diffuser 3 is provided with fan 4, fan 4 is connected with the input circuit of lamp socket 1 by the wire be arranged in diffuser 3 interlayer, and diffuser 3 outer surface and lamp socket 1 end face are provided with multiple fin or thermal column 5.
Dried by fan 4, the dust bottom removing lamp socket 1 in LED lamp bead 2, improves radiating effect and light leads to efficiency, and fin or thermal column use copper, iron or aluminium material to play thermolysis, perfect heat-dissipating, extend the service life of LED street lamp.
Embodiment two
On the basis of embodiment one, fan 4 installation by adhering that the present embodiment provides is on diffuser 3 inwall, and fan 4 is towards lamp socket 1 bottom surface; Fan 4 is multiple, is evenly distributed in diffuser 3 circumferential inner surface.
In order to strengthen dust removing effects, fan 4 is towards the direction of lamp socket 1 bottom surface LED lamp bead 2, and multiple fan 4 dust removing effects is better, extends the service life of LED street lamp.
More than exemplifying is only illustrate of the present invention, does not form the restriction to protection scope of the present invention, everyly all belongs within protection scope of the present invention with the same or analogous design of the present invention.
