Abstract

The utility model relates to a high power cold light source road lamp. A lamp pole is a pipe fitting, the center of which is provided with a channel, and a gas inlet is below the lamp pole. The rear end of a lamp shell (being close to the lamp hole is rear) is provided with a connecting pipe that is connected with an elbow at the upper end of the lamp pole. A gas outlet grid port is below the front end of the lamp shell. An LED luminotron and a lamp holder are below the lamp shell. A graphite absorber plate is connected with the lamp holder. The inner side above the lamp shell is provided with a flange that is connected with a support through a screw, the lower edge of the support is provided with a boss and a screw is used to connect the support with the graphite absorber plate. The support is embedded with a radiating part that consists of a large-caliber metal pipeline, a small-caliber metal pipeline and a radiating fin. The lower end of the radiating part pushes against the upper surface of the graphite absorber plate, and the heat absorbed by the graphite absorber plate is then transferred to the radiating part. The atmosphere enters from the gas inlet at the lower part of lamp pole, goes upwards from an inner cavity of the lamp pole and then rustles through the radiating part, thus discharging the heat from the gas outlet grid port at the front end of the lamp shell to the air. In application, the high power cold light source road lamp is small in size, light in weight and good in radiation effect.

Description

High-power cold light source street lamp

Affiliated technical field

The utility model relates to the high-power cold light source street lamp with LED.

Background technology

Existing with the high-power cold light source street lamp of LED, there are high heat and the contradiction of dispelling the heat.In order to solve heat dissipation problem, the lamp socket back adopts heavy in section aluminium sheet to dispel the heat.Its weak point is: volume is big, Heavy Weight, and radiating effect is poor.

The utility model content

The purpose of this utility model is to provide high-power cold light source street lamp in order to overcome above-mentioned weak point, and volume is little, and is in light weight, good heat dissipation effect.

The technical scheme that its technical problem that solves the utility model adopts is: high-power cold light source street lamp, lamp stand is the pipe fitting that there is passage in central authorities, has the air inlet that communicates with atmosphere below lamp stand.The lamp housing of high-power cold light source street lamp, its top is turtleback, and its rear end is (near after lamp stand is, it is preceding leaving lamp stand) connecting plate arranged, there is the tube connector of hollow at the middle part of connecting plate, and the internal diameter of tube connector is enclosed within on the external diameter of lamp stand upper end elbow, and uses the fastening screw lock.Below the lamp housing front end, have one to discharge gas grid mouth.Below lamp housing, the only high-power cold light source LED of 20-150 luminous tube is installed on the lamp socket, in the outside of LED luminous tube Transparent lamp shade is housed, and the outside of Transparent lamp shade is connected gland on the lamp socket with screw.What be connected with lamp socket is the graphite absorber plate, the heat absorption on high-power cold light source LED luminous tube and the lamp socket is come, and store.Inboard bossed flange is connected with support at lugs position with screw above lamp housing, in the lower edge of support convex is arranged, and support and graphite absorber plate is coupled together with screw in the convex position.On support, be inlaid with thermal component, thermal component is made up of heavy caliber metallic conduit, small diameter metal pipeline, heat radiation accessory pinna, the inner chamber of the heavy caliber metallic conduit that exports at two has the small diameter metal pipeline of 3-9 root two outlet, heat radiation accessory pinna in 4-12 road is arranged in the outside of heavy caliber metallic conduit, and the heat radiation accessory pinna is a hardware.Conflict on the graphite absorber plate in the lower end of thermal component, like this, the heat that the graphite absorber plate absorbs and stores just passes to thermal component.Because lamp stand has certain height, the bottom of lamp stand and upper end exist atmospheric pressure poor, and atmosphere enters from the air inlet of lamp stand bottom, by the lamp stand inner chamber upwards, come out from the lamp stand upper end, brushed thermal component again, heat constantly is discharged into the atmosphere from the grid mouth of giving vent to anger of lamp housing front end.

Effective effect of the present utility model is, uses high-power cold light source street lamp of the present utility model, and volume is little, and is in light weight, good heat dissipation effect.
