The beneficial effect of the utility model is:

1, the utility model adopts the high-strength aluminum alloy material, and radiator and power supply adopt built-in design, have effectively prevented the influence that dust and working environment thereof cause light fixture; Radiator is that aluminium extruded is one-body molded, and every fin all is that trapezium structure is cut and milled out several groovings, and the special process processing has been done on the surface, efficiently solves the problem of built-in radiator heat-dissipation efficient.

2, the utility model is the square factory of an a kind of great power LED lamp, and it is square that squared design makes illumination zone, helps the luminous intensity distribution design of large space illumination, and power reaches 100 ~ 200W, the illumination of alternative traditional 400W high-pressure mercury lamp.

3, the protruding structural design of four rib truncated cone shapes improves the heat-sinking capability of great power LED factory building lamp greatly, and power supply is close to loam cake and is fixed, and utilizes loam cake to power supply apparatus heat radiation to be provided, for power supply provides a good operation temperature.

4, the utility model great power LED factory building lamp has louvre or heat radiation seam around four rib truncated cone shape convexities and lower box body; Make air-flow form the heat loss through convection system that flows into the top outflow from the below; Wherein the part that caves inward of the protruding both sides of four rib truncated cone shapes has been done safeguard function to the louvre or the heat radiation seam at two ends; Make the dust and other impurities that falls from the top can not get into enclosure interior; Have certain dirt exclusion capabilities, cause lamp body to use inside still not have a large amount of dust accretions for a long time, need not frequent maintenance.

5, the reflector in lampshade, installed of the utility model great power LED factory building lamp, the light that light source is sent is utilized effectively, and lampshade adopts safety glass, light transmittance is strengthened greatly and has certain impact resistance.

6, the utility model great power LED factory building lamp adopt cross section be circular sealing ring as seal, have higher sealing, make lamp body have waterproof, explosion-proof ability, can be in the place use inflammable, explosive, that fuel gas and combustible dust are arranged.
