Abstract

A projector includes a housing, an optical unit, and a heat transfer module. The housing is made of a material with high thermal conductivity having a window. The optical unit is accommodated in the housing and further includes a light source, a panel, and a projection lens. The light source provides a light. The panel modulates the light. The projection lens projects the modulated light to leave the window. The heat transfer module is accommodated in the housing and connected the optical unit and the housing to transfer heat from the optical unit to the housing. Particularly, the projector is a cooling-fan saved projector. In addition, the projector further comprises a computer card adapter and a computer card inserted into the computer card adapter.

Claims

1. A projector, comprising:

a housing, made of a material with high thermal conductivity having a window;

an optical unit accommodated in said housing, comprising;

a light source for providing light;

a panel for modulating said light; and

a projection lens for projecting said modulated light to leave said window;

a heat transfer module, accommodated in said housing, for connecting said optical unit and said housing, to transfer heat from said optical unit to said housing.

2. A projector according to claim 1, wherein said projector is a cooling-fan saved projector.

3. A projector according to claim 1, said projector further comprises a computer card adapter and a computer card insertable into said computer card adapter.

4. A projector according to claim 3, wherein said computer card is a PCMCIA card.

5. A projector according to claim 3, further comprising a control circuit for processing signals of DVB-T/H, MP4, 1-Seg, RF Tx/Rx, DVD, or AV IN/OUT from said computer card in order to control said panel.

6. A projector according to claim 5, wherein said computer card adapter is connected to said control circuit via wireless.

7. A projector according to claim 1, wherein said heat transfer module connects said light source and said housing to transfer heat from said light source to said housing.

8. A projector according to claim 7, wherein said rear of said light source is connected to said heat transfer module.

9. A projector according to claim 7, wherein said bottom of said housing is connected to said heat transfer module.

10. A projector according to claim 1, wherein said heat transfer module further comprises a heat pipe.

11. A projector according to claim 1, wherein said heat transfer module further comprises a heat sink.
