Abstract
The run up characteristics of BR30 reflector compact fluorescent lamps are investigated to optimize lamp design for performance improvements. The design is optimized based on the current reflector amalgam lamp, characterized in that the solid mercury is added into the discharge tube and the paraffin wax is put at the bottom of the reflector to connect the discharge tube and the reflector bottom together. The experimental results show that the run-up time can be shortened by about 20 s, the light efficacy can be increased by about 5 lm/W, and the bottom temperature of the discharge tube can be reduced by about 25°C by the optimized reflector lamp design.
