Abstract

An exemplary infrared light bar includes at least one light source for emitting infrared light, an elongated infrared light guide member, and a reflecting layer. The infrared light guide member includes at least one light incident surface for receiving the infrared light and a longitudinal side surface consisting of a covered portion and a plurality of exposed portions. The reflecting layer is formed on the entire covered portion of the longitudinal side surface for blocking the infrared light transmitting therethrough. The reflecting layer defines a plurality of spaced openings spatially corresponding to the exposed portions for allowing the infrared light to exit therefrom.

Claims

1. An infrared light bar comprising:

at least one light source for emitting infrared light;

an elongated infrared light guide member, the infrared light guide member comprising at least one light incident surface for receiving the infrared light and a longitudinal side surface consisting of a covered portion and a plurality of exposed portions; and

a reflecting layer formed on the entire covered portion of the longitudinal side surface for blocking the infrared light transmitting therethrough, the reflecting layer defining a plurality of spaced openings spatially corresponding to the exposed portions for allowing the infrared light to exit therefrom.

2. The infrared light bar of claim 1, wherein the infrared light guide member comprises a first end surface and an opposing second end surface, and the longitudinal side surface is connected between the first and second end surfaces.

3. The infrared light bar of claim 2, wherein the first end surface is the light incident surface, and the infrared light guide member tapers from the second end surface to the first end surface.

4. The infrared light bar of claim 2, wherein the at least one light source includes two light sources disposed at opposite sides of the infrared light guide member, the first and second end surfaces are the light incident surfaces, and the infrared light guide member tapers from the first and second end surfaces to a middle portion thereof.

5. The infrared light bar of claim 1, wherein the at least one light incident surface is differently oriented from the longitudinal side surface.

6. The infrared light bar of claim 1, further comprising a plurality of protrusions formed on the exposed portions of the longitudinal side surface.

7. The infrared light bar of claim 6, wherein the protrusions are hemispherical protrusions.

8. The infrared light bar of claim 6, wherein the protrusions each have a curved surface.

9. A game device comprising:

an infrared light bar as described in claim 1, and

a remote controller including an infrared sensor for sensing the infrared light from the infrared light bar, the remote controller configured for determining a location and distance thereof relative to the infrared light bar.

10. The game device of claim 9, wherein the light source is an infrared light emitting diode.

11. The game device of claim 9, further comprising a game console and a display device, wherein the game console is connected with the display device.

12. The game device of claim 11, wherein the infrared light bar is aligned with the display device.
