Abstract
The utility model provides a high power LED road lamp comprising a diffuser, a circuit chamber cover plate, a lamp body, a lamp pole and a base, wherein the lamp body comprises a light source chamber, an electric appliance chamber and a metal radiating fin; the light source chamber is internally provided with a plurality of LED modules; the electric appliance chamber is internally provided with a drive circuit; and the lamp pole is connected with the metal radiating fin. The high power LED road lamp has the following technical effects: 1. transferring the heat generated by LED to a fixing support of the high power LED road lamp, namely the lamp pole through conduction of metal or liquid, allowing the lamp pole to join in radiation, increasing the radiating area and diffusing the heat to air and improving the radiating efficiency since the mobile air takes away the heat; and 2. being simple in structure, low in manufacturing cost and high in practical value.
Description
Technical field
The utility model relates to a kind of semiconductor lighting equipment, and 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.
The utility model content
The purpose of this utility model is to address the above problem, and a kind of high-power LED street lamp that can dispel the heat effectively is provided.
High-power LED street lamp of the present utility model, 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 utility model, 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 utility model, 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 utility model 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 utility model 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 embodiment 1 of the present utility model;
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.
