A MINIATURISED PROJECTION DEVICE USING AN LED ARRAY AND DICHROIC WEDGE |
摘要 |
The present invention relates to an image projection device having a linear array of LED's in a common substrate, a common lens group to collimate light from each LED, and a single dichroic wedge having dichroic coatings for reflecting each light source to a condensing means which condenses the light to a distal surface. The image projection device therefore provides for a smaller optical package which is more easily accommodated in mobile devices such as mobile telephones, and which is simple and cheap to manufacture. |
