Abstract
The invention provides a high-power LED street lamp which comprises a transparent cover, a circuit room cover plate, a lamp body, a lamp pole and a base, wherein the lamp body comprises a light source room, an electric room and a metal radiating fin; the light source room is internally provided with a plurality of LED modules; the electric room is internally provided with a drive circuit; and the lamp pole is connected with the metal radiating fin. The high-power LED street lamp has the advantages that heat generated by LEDs is transmitted to a fixed supporting body, i.e. the lamp pole of the high-power LED street lamp, through metal conduction or liquid conduction so as to ensure that the lamp pole participates in radiation, thereby increasing the radiating area; heat is emitted into air and taken away by flowing air, thereby improving the radiating efficiency; and the high-power LED street lamp has simple structure, low manufacture cost and high practical value.
Description
Technical field
The present invention relates to a kind of semiconductor lighting equipment, specifically, relating to a kind of is the street lamp of light source with the great power LED.
Background technology
High-power LED street lamp, as the term suggests be single power greater than more than 1 watt, adopt the street lamp of New LED semiconductor light sources, be applicable to urban road, pavement, square, school, park, garden, residential area, plant area and other need the place of outdoor lighting.Great power LED as the 4th generation electric light source, title with " green illumination light source ", have little, the safe low-voltage of volume, good characteristics such as the life-span is long, electro-optical efficiency is high, response speed is fast, energy-saving and environmental protection, will replace traditional incandescent lamp, halogen tungsten lamp and fluorescent lamp and become the light source of new generation of 21 century.,, install and use simple, the less relatively great power LED device of volume and in most illumination, will replace traditional low-power LED device from angle of practical application.
Great power LED is better than common low-power LED widely aspect heat dispersion, its led chip is connected on the dummy slider of a metal, heat dispersion obtains very big improvement, but low-power LED is used for extraordinary light fixture, or be used for the light fixture that adverse circumstances are used, the shell protection grade of these light fixtures is generally all more than IP65, if shell is nonmetallic materials, although in the LED connection aluminium base, if the heat on the aluminium base can not be conducted to case surface effectively, then the heat of Ju Jiing can make the temperature of aluminium base sharply rise, cause temperature too high, increase the possibility that LED lost efficacy, cause the aggravation of LED light decay, the lost of life.
The radiating mode of high-power LED street lamp mainly contains in front: Natural Heat Convection, install fan forced heat radiation, heat pipe and loop heat pipe heat radiation etc. additional, wherein Natural Heat Convection is merely able to satisfy substantially the heat dissipation problem of high-power LED street lamp, and install fan forced heat radiation mode system complex additional, reliability is low, heat pipe and loop heat pipe radiating mode cost height.Generally speaking, heat dissipation problem is still one difficulty that hinders the high-power LED street lamp safe handling.
Summary of the invention
The objective of the invention is to address the above problem, a kind of high-power LED street lamp that can dispel the heat effectively is provided.
High-power LED street lamp of the present invention, comprise diffuser, circuit room cover plate, lamp body, lamp stand, base, wherein lamp body comprises light source chamber, electric apparatus room and metal fin, is provided with many led modules in the light source chamber, be provided with drive circuit in the electric apparatus room, said lamp stand links to each other with metal fin.
Preferably,
High-power LED street lamp of the present invention, its lamp stand inner hollow, lamp stand and metal fin ways of connecting are that metal fin is in the lamp stand outside.
Equally preferably,
High-power LED street lamp of the present invention, its lamp stand inside is filled with water, and lamp stand and metal fin ways of connecting are that lamp stand passes metal fin.
High-power LED street lamp of the present invention has following technique effect:
1, to be delivered to the fixed support body of high-power LED street lamp be on the lamp stand to the heat that LED is produced by metal conduction or liquid conductive, allow lamp stand participate in heat radiation, increased area of dissipation, heat is dispersed in the air, take away heat by flow air, improved radiating efficiency;
2, simple in structure, low cost of manufacture, practical value height.
Description of drawings
The present invention is described in further detail below in conjunction with specification drawings and specific embodiments.
Fig. 1 is the structural representation of the high-power LED street lamp of embodiments of the invention 1;
Wherein, 1 is diffuser, and 2 is the circuit room cover plate, and 3 is that light source chamber, 4 is led module, and 5 is the circuit chamber, and 6 is drive circuit, and 7 is metal fin, and 8 is lamp stand.
The specific embodiment
Embodiment 1
As shown in Figure 1, the high-power LED street lamp of present embodiment, comprise diffuser 1, circuit room cover plate 2, lamp body, lamp stand 8, base, wherein lamp body comprises light source chamber 3, electric apparatus room 5 and metal fin 7, be provided with many led modules 4 in the light source chamber 3, be provided with drive circuit 6 in the electric apparatus room 5, lamp stand 8 inside are filled with water, lamp stand 8 links to each other with metal fin 7, and lamp stand 8 is that lamp stand 8 passes metal fin 7 with metal fin 7 ways of connecting.
The high-power LED street lamp of present embodiment is transmitted to the heat that LED produces in the water of lamp stand by metal fin when heat radiation, then heat is dispersed in the air, takes away heat by air.
Embodiment 2
The high-power LED street lamp of present embodiment, comprise diffuser, circuit room cover plate, lamp body, lamp stand, base, wherein lamp body comprises light source chamber, electric apparatus room and metal fin, be provided with many led modules in the light source chamber, be provided with drive circuit in the electric apparatus room, the lamp stand inner hollow, lamp stand links to each other with metal fin, and lamp stand and metal fin ways of connecting are that metal fin is in the lamp stand outside.
The high-power LED street lamp of present embodiment is transmitted to the heat that LED produces on the lamp stand by metal fin when heat radiation, then heat is dispersed in the air, takes away heat by flow air.
