Abstract
The utility model relates to a high-power LED road lamp and comprises a plurality of LED lamps, an aluminum plate, a shell, a copper heat conducting pipe and a heat radiating sheet. The LED lamp is fixed on the aluminum plate, the aluminum plate is connected with the copper heat conducting pipe, the copper heat conducting pipe is connected with the heat radiating sheet, the outer part of the copper heat conducting pipe is a copper pipe, the internal hollow cavity of the copper heat conducting pipe is filled with heat conducting liquid, and the heat radiating sheet is connected with the shell. The beneficial effect of the utility model is as follows that heat radiated from the LED lamp can be conducted out and dissipated in time, brightness maintenance of the road lamp can be guaranteed and service life of the road lamp can be extended.
Description
Technical field
The utility model relates to a kind of LED street lamp, particularly a kind of high-power LED street lamp.
Background technology
At present, street lamp has become the indispensable illuminations of city night life.General street lamp needs work for a long time, and needs to adapt to various bad weathers, so the life-span of general street lamp is not long.Also there is the high shortcoming of power consumption in traditional street lamp, has solved the high shortcoming that consumes energy so the LED light emitting diode is applied to the street lamp field.But light emitting diode, particularly large-power light-emitting diodes, owing to work under various environment for a long time, its heat dissipation problem becomes the matter of utmost importance that influences lifetime of LED.For solving the heat dissipation problem of high-power LED street lamp, disclosed a kind of high-power LED street lamp of Chinese patent CN1821651 and the disclosed a kind of high-power LED street lamp of Chinese patent CN1945104 have all carried out a series of improvement, but effect is not fairly obvious, installed fin additional as the disclosed a kind of high-power LED street lamp of Chinese patent CN1945104, but the heat-transfer rate of fin itself is slow, can not in time heat be derived and heat radiation.
The utility model content
The purpose of this utility model provides a kind of high-power LED street lamp, overcomes existing high-power LED street lamp heat conduction, the slow shortcoming of heat radiation.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of high-power LED street lamp, comprise some LED lamps, aluminium sheet, shell, copper heat pipe, fin, described LED lamp is fixed on the aluminium sheet, being connected of described aluminium sheet with the copper heat pipe, described copper heat pipe connects fin, copper heat pipe outside is a copper pipe, and the internal cavities of copper heat pipe has heat-conducting liquid, and described fin is connected with shell.
The beneficial effect of high-power LED street lamp described in the utility model is: the heat that can in time the LED lamp be sent is derived and is distributed, and guarantees that the brightness of street lamp is kept, and prolongs the service life of street lamp.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the structural representation of high-power LED street lamp described in the utility model;
Fig. 2 is the sectional view of high-power LED street lamp copper heat pipe described in the utility model.
Among the figure:
1, LED lamp; 2, aluminium sheet; 3, shell; 4, copper heat pipe; 5, fin; 6, heat-conducting liquid; 7, copper pipe.
The specific embodiment
Shown in Fig. 1-2, high-power LED street lamp described in the utility model, comprise some LED lamps 1, aluminium sheet 2, shell 3, some copper heat pipes 4, fin 5, described some LED lamps 1 are fixed on the aluminium sheet 2, described LED lamp 1 adopts parallel connection or series system to connect, being connected of described aluminium sheet 2 with some copper heat pipes 4, described copper heat pipe 4 is connected with fin 5, described copper heat pipe 4 outsides are copper pipes 7, the internal cavities of copper heat pipe 4 is marked with heat-conducting liquid 6, and described fin 5 is connected with shell 3.
The described LED lamp 1 luminous heat that produces is derived rapidly by copper heat pipe 4, the heat that will derive connects shell 3 heat radiations from the fin 5 of end again, thereby avoided LED lamp 1 commonly used directly to be connected, the service life that causes heat to reduce LED lamp 1 in the accumulation of LED lamp 1 place with fin 5.
Claims (2)
1. high-power LED street lamp, comprise some LED lamps, aluminium sheet, shell, copper heat pipe, fin, described LED lamp is fixed on the aluminium sheet, it is characterized in that: being connected with the copper heat pipe of described aluminium sheet, described copper heat pipe connects fin, and described fin is connected with shell.
2. high-power LED street lamp according to claim 1 is characterized in that: the internal cavities of described copper heat pipe has heat-conducting liquid.
