Abstract

A switch apparatus includes a Light Emitting Diode (LED) housing and a light guide pole. The LED housing includes at least one LED light source and a switch. The switch is capable of being actuated to light the at least one LED light source. The light guide pole is capable of transmitting light. The light guide pole is removably embedded in the LED housing to contact with the switch. The light guide pole presses the switch to drive the at least one LED light source to light.

Claims

1. A switch apparatus, comprising:

a light emitting diode (LED) housing comprising at least one LED light source and a switch, the switch capable of being triggered to light the at least one LED light source; and

a light guide pole being capable of transmitting light from the at least one LED light source;

the light guide pole removably embedded in the LED housing, wherein the light guide pole is capable of pressing the switch to trigger the at least one LED light source to light by moving relative to the LED housing.

2. The switch apparatus of claim 1, wherein the switch is a resilient metal piece.

3. The switch apparatus of claim 2, wherein the metal piece is located under the light guide pole.

4. The switch apparatus of claim 2, wherein a pressing portion is formed on a bottom portion of the light guide pole.

5. The switch apparatus of claim 1, wherein each LED light source produces a single light color;

a plurality of parallel LED light sources have different color light.

6. The switch apparatus of claim 5, wherein a plurality of parallel LED light sources produce light with pulse-width modulation.

7. The switch apparatus of claim 1, wherein the LED housing is encapsulated by Dual In-line Package (DIP).

8. The switch apparatus of claim 1, wherein the LED housing is encapsulated by Surface-mount technology (SMT).

9. The switch apparatus of claim 1, wherein the at least one LED light source is located under the light guide pole.

10. The switch apparatus of claim 1, wherein the light guide pole is generally transparent.

11. A LED lighting apparatus, comprising:

a light emitting diode (LED) housing comprising at least one LED light source and a switch, the switch is capable of operating the LED light source; and

a light guide pole being capable of transmitting light from the at least one LED light source;

the light guide pole removably embedded in the LED housing, the at least one LED light source and the switch located under the light guide pole, wherein the light guide pole is capable of pressing the switch to trigger the at least one LED light source to light by moving relative to the LED housing.

12. The LED lighting apparatus of claim 11, wherein the switch is a resilient metal piece.

13. The LED lighting apparatus of claim 12, wherein a pressing portion is formed on a bottom portion of the light guide pole.

14. The LED lighting apparatus of claim 11, wherein each LED light source produces a single light color;

and a plurality of parallel LED light sources emits more than one color of light.

15. The LED lighting apparatus of claim 14, wherein a plurality of parallel LED light sources produce light with pulse-width modulation.

16. The LED lighting apparatus of claim 11, wherein the LED housing is encapsulated by Dual In-line Package (DIP).

17. The LED lighting apparatus of claim 11, wherein the LED housing is encapsulated by Surface-mount technology (SMT).

18. The LED lighting apparatus of claim 11, wherein the at least one LED light source is a three original color LED light source for emitting light with an appearance of a color different that the three original LED colors.

19. The LED lighting apparatus of claim 11, wherein the light guide pole is generally transparent.

20. The LED lighting apparatus of claim 11, wherein the light guide pole is generally translucent.
