  • Patent number: 8801192
    Abstract: A light source module and a projector using the same are provided. The light source module includes a monochromatic light source emitting a monochromatic light, a rotating wheel having a light transmitting area and a wavelength transforming area, a filter wheel rotating at a same rotation speed with the rotating wheel, and a dichroic mirror disposed between the rotating wheel and the filter wheel. The wavelength transforming area is coated with a first wavelength transforming material capable of transforming the first color light into a second color light. The filter wheel has a first color filter area and a second color filter area respectively corresponding to the light transmitting area and the wavelength transforming area. The dichroic mirror reflects the first color light to the rotating wheel and allows the second color light to transmit therethrough.

  • Patent number: 8256930
    Abstract: A light-emitting diode module includes a transparent base, a support and a plurality of light-emitting chips. The base has a plurality of cavities separated from each other by a predetermined distance in order to respectively receive the light-emitting chips to form light-exiting areas. The base has a reflecting portion opposite to the cavities. The reflecting portion is at least one inclined plane for reflecting light that have projected outside walls of the cavities to the peripheral area of the light-emitting areas in order to increase the uniformity of the light source. In addition, the light-emitting chips are arranged to form a line or surface light source of any sizes by adjusting the numbers of the cavity and the light-emitting chips.
