Reasonable selection of lamps from improving utilization coefficient

Selection of lamps should be made to the maximum extent of their luminous flux to the working surface, that is, a high utilization factor. The value of the system depends on the efficiency of lamps, lamps and lanterns, interior decoration and other factors. The results show that the main factor of the utilization coefficient is the direct flux of the lamp, and the change of the reflected light flux is not high when the room height changes. Short and wide room most of the direct light fall to the working face, the use of high coefficient; high and narrow room, direct light fall on the working surface of the part of the reduction, the use of coefficient. In the design, such as the use of coefficient is found to be low when the exchange of different light distribution lamps, in order to improve the utilization factor.
