Abstract
The utility model relates to an illuminator, in particular to a street lamp used on the outdoor streets. The street lamp includes an upper cover, a lower cover, a luminous element, ballast and a lamp post. The lamp post has a certain clearance with the ballast, a diversion opening is formed on the rear side of the upper cover, and a ventilation opening is formed on the lower cover. The diversion opening formed on the rear side of the upper cover has a shutter structure. The ventilation opening of the lower cover is arranged in the position close to the clearance between the lamp post and the ballast. In the street lamp, the convection of air is formed between the shutter on the rear side of the upper cover and the ventilation opening of the lower cover, thereby bringing the heat of the ballast away, lowering the temperature of the ballast and prolonging the service life of the ballast.
Description
[technical field]
The utility model relates to a kind of lighting device, especially relates to the roads light that uses on a kind of road out of doors.
[background technology]
General light fixture is made up of electric elements such as light-emitting component, cooperation ballasts, as roads light, brightness of illumination, working environment there is higher requirement, roads light of the prior art all is that electric elements such as lamp, reflection shield and ballast are put in same member cavity, the heat that the lamp that power is bigger produces is big, the thermal-arrest effect of reflection shield is arranged again, cause lamp interior to be difficult for heat radiation, influence the service life of electric elements.China utility model patent ZL02217363.3 discloses the street lamp that a kind of electric elements with light fixture and illumination section are separated from structure, and this street lamp does not thoroughly improve the working environment of electric elements, does not still have good heat-radiation effect.
[utility model content]
Technical problem to be solved in the utility model is to provide a kind of street lamp with good heat radiating effect.
The utility model is by the following technical solutions:
A kind of street lamp comprises loam cake, lower cover, light-emitting component, ballast, lamp stand, has certain interval between described lamp stand and the ballast, and described loam cake rear side is provided with flow-guiding mouth, is covered with ventilating opening under described.
The flow-guiding mouth of described loam cake rear side is a shutter.
The ventilating opening of described lower cover is located near the gap location between lamp stand and the ballast.
The ventilating opening of the shutter of loam cake rear side and lower cover forms cross-ventilation by the gap between low beam bar and the ballast in the utility model, and the heat of ballast is taken away, and reduces ballast temperature, prolongs ballast life.
[description of drawings]
The utility model is described in further detail in conjunction with specific embodiments with reference to the accompanying drawings.
Fig. 1 is the utility model structural representation.
[specific embodiment]
See also Fig. 1, a kind of street lamp comprises loam cake 1, lower cover 2, light-emitting component (figure does not show), ballast 3, lamp stand 4, has certain interval 5 between lamp stand 4 and the ballast 3, and loam cake 1 rear side is provided with flow-guiding mouth 11, and lower cover 2 is provided with ventilating opening 21.
Flow-guiding mouth 11 is shutter mount structures, can prevent that rainwater or dust from entering in the loam cake 1, but air can enter the formation convection current.
The ventilating opening 21 of lower cover 2 is located near 5 places, gap between lamp stand 4 and the ballast 3.So that air forms good cross-ventilation through the gap 5 between flow-guiding mouth 11, lamp stand 4 and the ballast 3 of loam cake 1, the ventilating opening of lower cover 2, the heat of ballast 3 is taken away, reduce ballast 3 temperature, prolong 3 life-spans of ballast.The good heat radiation function of tool.
Claims (3)
1, a kind of street lamp comprises loam cake, lower cover, light-emitting component, ballast, lamp stand, it is characterized in that: have certain interval between described lamp stand and the ballast, described loam cake rear side is provided with flow-guiding mouth, is covered with ventilating opening under described.
2, a kind of street lamp as claimed in claim 1, it is characterized in that: the flow-guiding mouth of described loam cake rear side is a shutter.
3, a kind of street lamp as claimed in claim 1, it is characterized in that: the ventilating opening of described lower cover is located near the gap location between lamp stand and the ballast.
