Abstract

An illumination apparatus includes a lampshade, a light source module and a condensing plate. The light source module is disposed in the lampshade, and has a light-emitting diode (LED) device and a circuit board. The LED device is disposed on the circuit board. The condensing plate is disposed in the lampshade and disposed over the LED device. The condensing plate has a condensing element disposed corresponding to the LED device.

Claims

1. An illumination apparatus, comprising:

a lampshade;

a light source module, which is disposed in the lampshade and has a light-emitting diode (LED) device and a circuit board, wherein the LED device is disposed on the circuit board; and

a condensing plate, which is disposed in the lampshade and over the LED device and has a condensing element disposed corresponding to the LED device.

2. The illumination apparatus of claim 1, wherein the condensing plate has a plate with a through hole, and the condensing element is disposed inside the through hole.

3. The illumination apparatus of claim 1, wherein the condensing plate has a plate, and the condensing element and the plate are integrally formed.

4. The illumination apparatus of claim 1, wherein the condensing element has a concave part and the LED device is disposed adjacent to the concave part.

5. The illumination apparatus of claim 4, wherein a bottom surface of the concave part is a convex surface protruding toward the LED device.

6. The illumination apparatus of claim 4, wherein a bottom surface of the concave part has a Fresnel pattern.

7. The illumination apparatus of claim 4, wherein the condensing element has a light-outputting surface disposed opposite to a bottom surface of the concave part.

8. The illumination apparatus of claim 7, wherein the light-outputting surface has a Fresnel pattern.

9. The illumination apparatus of claim 1 further comprising:

a diffusing plate, which is disposed in the lampshade and facing a light-outputting surface of the condensing plate.

10. The illumination apparatus of claim 9 further comprising:

a Fresnel pattern plate, which is disposed between the diffusing plate and the condensing plate.

11. The illumination apparatus of claim 1 further comprising:

a heat-dissipating fan connected to the lampshade.

12. A condensing plate, comprising:

a condensing element having a concave part disposed on a light-inputting surface of the condensing plate.

13. The condensing plate of claim 12, wherein a LED device is disposed in the concave part.

14. The condensing plate of claim 12 further comprising:

a plate having a through hole, wherein the condensing element is disposed inside the through hole.

15. The condensing plate of claim 12 further comprising:

a plate, wherein the condensing element and the plate are integrally formed.

16. The condensing plate of claim 12, wherein a bottom surface of the concave part is a convex surface.

17. The condensing plate of claim 12, wherein a bottom surface of the concave part has a Fresnel pattern.

18. The condensing plate of claim 12, wherein the condensing element has a light-outputting surface disposed opposite to a bottom surface of the concave part.

19. The condensing plate of claim 18, wherein the light-outputting surface has a Fresnel pattern.
