| Abstract: | The uniform and collimating LED lamps using one LED power chip and applying to a single LCD panel mini-projector is presented. Form lenses with total internally reflecting surface are designed by a theoretical tracing method and optical tracing software (ASAPTM) and obtained a set optimal lens structure parameters for our aim and condition. It is numerically shown that the 85.4% illumination uniformities on detector and 4.8°of full angle at the half maximum of the luminous intensity when the LED size is 1 mm×1 mm of Lambertian distribution. |
| Keywords: | LED power chip mini-projector illumination uniformity power efficiency full angle at the half maximum of the luminous intensity |
