Embodiment 1

[0041] Embodiment 1, AC220V / 50Hz city grid direct power supply 80W single-head LED street lamp

[0042] In this embodiment 'AC220V / 50Hz city power grid direct power supply 80W single-head LED street lamp', the light source circuit part is composed of 80 Power LEDs (power LEDs) with a rated power consumption of 1W and an irradiation angle of 90 degrees. The overall light source circuit is installed on an aluminum On the alloy transition substrate, the width and thickness of the transition substrate match the double-winged aluminum alloy lamp housing. The installation method is as follows: Figure 4 As shown: the aluminum alloy transition substrate carrying the LED light source circuit is inserted from the slot 2, and bolts are added for fastening and positioning; the overall LED street lamp uses 3mm thick ultra-clear tempered glass as the light-transmitting panel, and is inserted into the slot 3, After the whole is in place, use glass glue to seal along the periphery; the drive...

Embodiment 2

[0043] Embodiment 2, AC220V / 50Hz city grid direct power supply 250W strip spot LED street lamp

[0044] The principle of this embodiment 'AC220V / 50Hz city grid direct power supply 250W strip spot LED street lamp' is the same as that of Embodiment 1. Such as Figure 5 As shown, three 80W LED light source boards are installed at positions 4, 5, and 6 respectively. It should be noted that: the LED light source board directly below is installed at position 5, and its radiation angle is 60 degrees. Although the other two LED light source boards also consume 80W, their radiation angle is 40 degrees. The street lamp basically has no zebra effect, and the lighting effect is better.

Embodiment 3

[0045] Embodiment 3. Double-wing spread-wing type LED street lamp heat dissipation lamp housing

[0046] as per Image 6 The extrusion die drawn from the design drawings shown in the figure is used to process aluminum profiles on the 280-ton aluminum profile extrusion equipment. Cut into 500mm length of LED street lamp housing, its shape is like figure 1 The shown double-wing extruded aluminum alloy LED street lamp housing. The actual weight of the lamp housing is only 6700g, which can effectively solve the heat dissipation problem of LED street lamps with 150W power consumption. When it is independently erected outdoors, there is no wind around, and the ambient temperature is 28°C, the temperature of the light source will reach equilibrium after one hour of lighting. The surface temperature of the lamp housing is about 45°C, and the surface temperature of the light source LED patch is about 66°C, which meets the heat dissipation design requirements. The lamp housing is ea...

Abstract

The invention discloses a lamp housing of an LED street lamp. The LED is gradually widespread in the aspect of street lamp application owing to a plurality of advantages such as energy saving, high efficiency and long service life and the like. The common LED lamp street at present adopts the structure and modeling which are compatible with the traditional street lamp. The modeling of a plurality of specially designed metal heat dissipation lamp housing does not break away from the influence of the traditional street lamp. The lamp housings has the disadvantages of big volume, heavy weight, poor heat dissipation effect; a plurality of lamp housings adopt heat dissipation technical measure of heat pipes, but have high popularization cost, and has poor practicability at present. The invention has the advantages that the multi-blade wing modeling structure obviously increases the effective heat dissipation area of aluminium alloy housing while reducing materials such as aluminium alloy, and is beneficial to improving heat dissipation effect. As the size and length is arbitrary, the lamp housing is applied to the lamps with different models, has novel modeling, light weight, simple and easy installation, low comprehensive cost, and is convenient to use. The lamp housing has positive significance for popularizing LED street lamps and increasing social and economic benefits.

Description

【Technical field】 [0001] The invention relates to a lamp housing, in particular to a multi-wing spread-wing type LED heat dissipation lamp housing. [0002] Since LED street lights have surpassed traditional street light sources with their excellent features such as high efficiency, long life, safety and environmental protection, they have gradually been widely recognized by the society. However, LED light sources have their special physical characteristics. Therefore, in terms of lighting applications, various non-traditional elements must be considered in the design of the lamp housing. The heat dissipation design level of the LED lamp housing is directly related to whether the LED light source can exploit its strengths and avoid its weaknesses. It is necessary to give full play to the advantages of its semiconductor solid-state lighting and effectively avoid its weakness of high temperature resistance. In addition, the structural design of the lamp housing is also very imp...
