Description
Technical field
The utility model relates to a kind of street lamp, relates in particular to a kind of LED street lamp.
Background technology
Energy shortage is the hot issue of the world today, in illuminating industry, light emitting diode (LED) is efficient because of its, energy-conservation, multiple advantage such as environmental protection, be to replace the energy consumption height, the first-selection of the traditional lighting that the life-span is short, but because LED is a kind of cold light source, the main illuminator of LED---wafer can produce very high operating temperature at work, if the operating temperature of LED can not be excreted, the wafer of LED will be in high temperature loses efficacy gradually, caused the LED street lamp life-span very short, restricted light emitting diode (LED) and replaced the energy consumption height, the process of the traditional lighting that the life-span is short, the heat dissipation problem of LED street lamp become the problem that people's urgent need will solve.
The utility model content
The utility model is to overcome above-mentioned weak point, purpose is to provide a kind of LED street lamp, this LED street lamp is by being glued with aluminium sheet on pcb board, not only accelerated the heat radiation of LED, and aluminium sheet also can play a reflex, in a life-span of improving the LED street lamp, two brightness that increase the LED street lamp have solved the deficiencies in the prior art part.
The utility model is to achieve the above object by the following technical programs: a kind of LED street lamp, comprise street lamp loam cake and lower cover, under cover and be provided with an opening, be coated with a transparent implosion guard on the opening, in the street lamp loam cake of closure and lower cover, be provided with several LED, an aluminium sheet, a pcb board, several LED are welded on the pcb board, and described aluminium sheet offers the hole that is complementary with several LED, and aluminium sheet is close on the pcb board that is welded with several LED.
Described several LED are 72 LED.
Electrical connection on the described pcb board between each LED is by the Copper Foil conducting.
The size and the implosion guard of described aluminium sheet, pcb board are complementary.
Described aluminium sheet is the aluminium sheet that has four bendings.
The beneficial effects of the utility model: the LED road lamp cooling of this structure is fast, and the life-span is long, good illumination effect.
Description of drawings
Fig. 1 is the structural representation of the LED street lamp among the utility model embodiment 1.
The specific embodiment
The utility model is further elaborated by embodiment below in conjunction with accompanying drawing:
Embodiment 1: as shown in Figure 1, a kind of LED street lamp, comprise street lamp loam cake 1 and lower cover 8, lower cover 8 is provided with an opening 7, be coated with a transparent implosion guard 6 on the opening 7, the street lamp loam cake 1 of closure and lower cover 8 are fixed on the fixed connecting rod 9 during use, in the street lamp loam cake 1 of closure and lower cover 8, be provided with 72 LED2, an aluminium sheet 3, a pcb board 4, described aluminium sheet 3 offers the hole that is complementary with 72 LED2, aluminium sheet 3 is close on the pcb board 4, the hole that 72 LED2 pass on the aluminium sheet 3 is electrically connected with pcb board 4, electrical connection on the described pcb board 4 between each LED is by the Copper Foil conducting, be provided with a Switching Power Supply 5 in pcb board 4 outsides, Switching Power Supply 5 provides stable voltage and current for each LED, described aluminium sheet, the size of pcb board and implosion guard 6 are complementary, and described aluminium sheet 3 is for having the aluminium sheet 3 of four bendings, and the thickness of aluminium sheet can be at 1mm---choose arbitrarily in the 3mm scope.
Adopt the LED street lamp of this structure, the heat conduction of working simultaneously of aluminium sheet and Copper Foil, the aluminium sheet heat radiation that strengthens bending is faster, the operating temperature of LED will be released external by aluminium sheet and copper platinum fast, through the shell volatilization, can allow the operating temperature of LED light fixture the inside be lower than 70 °, under such operating temperature, LED work could be more stable, and the life-span is longer!
