A Designing of LED Stage Lighting for Long Distance
A LED secondary-optics designing is an important step which decides the output efficiency and the uniformity of stage lighting. A green stage lighting requires that LED stage lights can increase the total flux and form a 4~6 m uniform circular spot at 30 m away. However, the LED stage lights currently on the market cannot meet these requirements. This article describes a new model of lighting design which can achieve both higher output power and more uniform circular spot. The model uses a uniform light stick, reflective prism and reflector to meet a longrange requirements. And the final output efficiency can be as high as 26%.
