Abstract
The utility model discloses a project lamp which comprises a project lamp body (1). The project lamp body (1) comprises a lamp housing (2), a light-emitting diode (LED) lamp (4) and two end covers (3) arranged at two ends of the lamp housing (2), a plurality of heat dissipation ribs (5) are arranged on the outer wall of the lamp housing (2), a partition board (6) is arranged on the inner wall of the lamp housing (2), a heat dissipation cavity (8) is arranged between the partition board (6) and the lamp housing (2), and a plurality of heat dissipation protrusions (7) which are distributed at intervals are arranged on the partition board (6) in the heat dissipation cavity (8). The project lamp has the advantages of being rapid in heat dissipation speed and long in service life.
Description
Technical field
The utility model relates to the lamp lighting technical field, specifically is a kind of Projecting Lamp.
Background technology
The effect of Projecting Lamp is to make the light fixture of specifying the projecting environment of illumination on the face to be illuminated, also claims spotlight.Usually, it can aim at any direction, and possesses the not structure of climate condition influence.Be mainly used in ore deposit, large tracts of land operation field, contour of building, stadium, viaduct, monument, park and flower bed etc.Projecting Lamp generally adopts the LED illumination, its lighting hours is long, power is larger, therefore lamp body generates heat easily, generally be provided with radiating ribs on the lamp housing outer surface of prior art Projecting Lamp, the dissipation of heat that this radiating ribs can be sent the LED lamp is gone out, if in hot weather or hot environment, use, only heat radiation is far from being enough to the heat that the LED lamp sends by the radiating ribs on the lamp housing outer surface, will cause like this radiating rate slow, increase the light decay of LED lamp, reduce illumination intensity, the long-time use service life that can shorten the LED lamp.
The utility model content
The technical problems to be solved in the utility model is, overcomes the defective of above prior art, provides that a kind of radiating rate is fast, the Projecting Lamp of long service life.
Technical solution of the present utility model is, a kind of Projecting Lamp with following structure is provided: it comprises the Projecting Lamp body, two end caps that described Projecting Lamp body comprises lamp housing, LED lamp and is installed in the lamp housing two ends, the outer wall of described lamp housing is provided with many radiating ribs, the inwall of described lamp housing is provided with a dividing plate, be provided with a heat radiation chamber between described dividing plate and the lamp housing, the dividing plate in the described heat radiation chamber is provided with a plurality of heat radiation spaced apart projections.
After adopting above structure, the utility model Projecting Lamp compared with prior art, have the following advantages: the envelope inner wall of this Projecting Lamp is provided with a dividing plate, is provided with a heat radiation chamber between described dividing plate and the lamp housing, and the dividing plate in the described heat radiation chamber is provided with a plurality of heat radiation spaced apart projections.This heat radiation projection and heat radiation chamber make heat radiation more evenly fast, therefore can reduce the light decay of LED lamp, guarantee its illumination intensity, prolong the service life of LED.
As a kind of improvement, be equipped with a plurality of air vents on described two end caps, and each air vent is connected with the heat radiation chamber.Louvre on these two end caps communicates with the heat radiation chamber, thereby makes air form convection current in the heat radiation chamber, can utilize fast the extraneous air heat radiation, makes radiating effect better.
