This utility model relates to the field of lighting technology, specifically to a shoe box light fixture.
Background technology:
LED shoe box lights, also known as LED area lighting lights, are the latest generation of LED lighting fixtures. With their superior performance, they can replace traditional single LED street lights, LED floodlights, and other LED lighting products. The overall design of the lamp adopts a square shape, with the lamp body and radiator parts echoing the overall rugged style, and adding some changes to the details to add some beauty. As it looks more like a shoe box in our daily life, it is called a shoe box lamp. At present, LED shoe box lights are widely used in parking lot lighting, road lighting, building lighting, sports hall lighting, basketball court lighting, billboard lighting, and so on.
At present, most of the heat dissipation bodies of the existing shoe box lamp fixtures are manufactured by die-casting technology. The post-processing steps of using die-casting technology to process the heat dissipation body are many, and the processing efficiency is low, resulting in a small output in mass production; Moreover, the die-casting process causes serious environmental pollution, which is not conducive to the physical and mental health of workers. Excessive surface flow patterns and oxidation slag on the heat dissipation body processed by die casting technology can reduce the heat conduction effect; During cooling, the internal micro shrinkage pores are too high, leading to a decrease in substantive thermal conductivity; The mold used for processing heat dissipation bodies through die casting technology has a shorter lifespan, relatively complex equipment, bulky volume, and increases material and transportation costs as well as outdoor maintenance costs. The heat dissipation body of traditional shoe box lamp fixtures uses die cast aluminum material, which has a low thermal conductivity. For example, the thermal conductivity of ADC12 die cast aluminum is around 90 watts/meter. Celsius, which has the problem of poor heat dissipation.
In summary, the existing heat dissipation bodies of shoe box lighting fixtures have problems such as low processing efficiency, severe environmental pollution, reduced thermal conductivity, short production equipment lifespan, high material costs, transportation costs, and outdoor maintenance costs.
Technical implementation elements:
