Description
Technical field
The utility model belongs to field of illuminating device, relates in particular to a kind of lighting of the indoor hoisting for the industrial and mineral factory building.
Background technology
The tradition bulkhead lamp capable mainly adopts high-pressure mercury lamp and Metal halogen lamp, and common power is 250 watts or 400 watts.
In the energy consumption of factory, lighting energy consumption occupies very large proportion, and for example, in the factory building thing of 40,000 square metres, the electric consumption on lighting load need to be about 400KW usually.Therefore, in the selecting of industrial light light fixture, how to realize that energy-saving and environmental protection are pendulum important topics in face of plant design person.
