An illuminated logo unit () includes a reflective board (), a pattern panel (), an illuminating device (), and a reflective film (). The pattern panel is arranged over the reflective board, and the reflective film is disposed under the pattern panel opposite to the reflective board. Much light emanating from the illuminating device is reflected more than once by the reflective film and the reflective board before it reaches the pattern panel. 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.

An image sensor package () includes a housing () defining a top opening, an image sensor () received in the housing, and a converging lens () 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.

A planar light source device () for a liquid crystal display device. The planar light source device includes a light source device () and a light guide plate (). The light source device includes a light-emitting element (), and an optical guiding member () that is hollow and has a reflective surface. The reflective surface receives light rays emitted by the light-emitting element, and guides the light rays out from a plurality of generally aligned through holes () defined in a front light-emitting surface () of the optical guiding member. The light guide plate has a light incident surface adjacent to the light source device. The planar light source device can greatly diminish possible dark regions on the light-emitting surface of the light guide plate, and provide uniform illumination for an LCD.
