Abstract: A process for forming a light guide plate with a reflection film includes: (a) providing a light guide plate (30), which has a light input surface (303) with light incident portions (3032), a bottom surface (304), a light output surface (301), and side surfaces (302); (b) attaching protection film (32) on the light incident portions and the light output surface; (c) providing a reflection solution; (d) dipping the light guide plate in the reflection solution; (e) removing the light guide plate from the reflection solution, and solidifying a portion of the reflection solution remaining on the light guide plate to thereby form a reflection film; and (f) removing the protection film to expose the light incident portions and the light output surface. Because the reflection film is directly attached to the light guide plate, there is no gap and no attendant leakage of light.

This enhances the overall brightness and uniformity of light beams of the illuminated logo unit. Even at night, the illuminated logo unit can be clearly viewed. The illuminated logo unit may be used for applications such as in a billboard, a logo displayed on a vehicle, and so on.

Abstract: An image sensor package (10) includes a housing (34) defining a top opening, an image sensor (14) received in the housing, and a converging lens (36) covering the opening to hermetically seal the housing and form a window for light to pass through into the housing. The image sensor has an active area which faces the converging lens and which is responsive to light. The converging lens not only provides hermetic sealing for the housing, but also converges light before the light strikes the active area of the image sensor. Accordingly, a focal length F is reduced, and a size of the image sensor package and the image sensor system can be reduced.
