Abstract

The utility model provides a light-emitting diode (LED) street lamp, which comprises a lamp base, a cover plate, a driving power supply and LED light sources, wherein the LED light sources are in a multi-module form and are assembled on the lamp base uniformly; radiating holes are formed in the lamp base on two sides of the LED light sources; the driving power supply is positioned at one end of the lamp base; and clamping positions are arranged on the cover plate, and the cover plate is clamped on a clamping groove of the lamp base by the clamping positions. Due to the adoption of the scheme, heat emitted by the LED light sources can be dissipated quickly by the radiating holes on two sides of the LED light sources and exhaust holes in side walls of two sides of the cover plate, so that the normal use of LEDs is ensured, and the service life of the LEDs is prolonged.

Description

A kind of LED street lamp

Technical field

The utility model relates to technical field of lamps, refers in particular to a kind of LED street lamp.

Background technology

LED(Lighting Emitting Diode) be light emitting diode, it is a kind of solid-state semiconductor devices, he utilizes semiconductor chip as luminescent material, by carrier compound energy of emitting surplus occuring causes photo emissions in semiconductor, directly send the light of the color such as red, yellow, blue, green, blue or green, orange, purple, white, the LED lamp utilizes LED as the produced lighting of light source exactly.The advantages such as LED has that volume is little, power consumption is low, long service life, photochromic pure, the high and low heat of brightness and environmental protection low-carbon (LC) are the 21 century novel green light sources of generally acknowledging in the world.Traditional LED is mainly used in the range light etc. that traffic fast demonstration field, auto industry comprise the backlight, reading lamp of automotive interior instrument board, acoustics indication lamp, switch and outside brake lamp, taillight, side lamp and head lamp etc., building aviation obstruction beacon, airport, nowadays the application outside Indoor environment, in the urban beautification, Landscape Lighting is also more and more extensive, as environment-friendly products, interior decoration also begins to popularize the LED lamp.

But the large-power light-emitting diodes namely chip of LED own can produce very large heat when work, if these heats distribute untimelyly, can have a huge impact its performance and life-span.Shortened the service life of LED lamp, so limited to a certain extent the range of application of LED lamp at lighting field, because brightness and the underpower of single led light source, can not just use as illumination, so existing LED lamp has generally all been assembled a plurality of led light sources, the number of the led light source of assembling is more, and the brightness of made LED lamp and power also will be higher.And the heat that the intensive use of LED can cause LED to produce is gathered in the less space in a large number and the problem that can not in time distribute, owing to being difficult in time distribute, heat cause the LED temperature to raise, can cause the decay of LED luminescent properties and aging rapidly, greatly reduce service life.

At present, LED street lamp on the market all is to adopt enclosed metal-back or plastic housing mostly, and the street lamp electric insulation of metal-back is poor, and the road lamp cooling effect of plastic lamp housing is bad.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of simple in structure, radiating rate is fast, the LED street lamp of long service life.

For achieving the above object, technical scheme provided by the utility model is; A kind of LED street lamp, it includes lamp socket, cover plate, driving power, led light source, and wherein, led light source is many module types, evenly is assemblied on the lamp socket, and the lamp socket of led light source both sides is equipped with louvre; Driving power is positioned at lamp socket one end;--cover plate is provided with screens, and is fastened on by screens on the draw-in groove of lamp socket.

Described led light source is four groups.

Respectively be provided with two row's steam vents on the sidewall of described cover plate both sides.

The utility model is after having adopted such scheme, and by the louvre of led light source both sides and the steam vent of cover plate both sides sidewall, the dissipation of heat that can rapidly led light source be sent guarantees the normal use of LED, prolongs its service life.

Description of drawings

Fig. 1 is overall structure schematic diagram of the present utility model.

The specific embodiment

The utility model is described in further detail below in conjunction with institute's drawings attached, preferred embodiment of the present utility model is: referring to accompanying drawing 1, the described LED street lamp of present embodiment includes lamp socket 1, cover plate 2, driving power 3, led light source 4, wherein, led light source 4 is four modules, evenly be assemblied on the lamp socket 1, the lamp socket 1 of led light source 4 both sides is equipped with louvre 5; Driving power 3 is positioned at lamp socket 1 one ends; Cover plate 2 is provided with screens 6, and is fastened on by screens 6 on the draw-in groove of lamp socket 1.Be equipped with two row's steam vents 7 on the cover plate 2 both sides sidewalls.The heat that led light source sends is discharged rapidly by the louvre 5 of the lamp socket 1 of led light source 4 both sides and the steam vent 7 on the cover plate 2 both sides sidewalls, and this structure can prolong the service life of LED street lamp greatly.

The embodiment of the above is the preferred embodiment of the utility model only, is not to limit practical range of the present utility model with this, so the variation that all shapes according to the utility model, principle are done all should be encompassed in the protection domain of the present utility model.
