Abstract

A light bulb includes a bulb body, two electrodes, and a light-transmissible conductive film. The two electrodes are connected to the bulb body. The light-transmissible conductive film covers the bulb body. A lighting fixture includes a lampshade, a cover, and a light-transmissible conductive film. The lampshade has an opening. The cover covers the opening. The light-transmissible conductive film is configured to be attached to the lampshade and the cover.

Claims

1. A light bulb, comprising:

a bulb body;

two electrodes connected to the bulb body; and

a light-transmissible conductive film covering the bulb body.

2. The light bulb as claimed in claim 1, wherein one of the electrodes is a grounding electrode to which the light-transmissible conductive film is electrically connected.

3. The light bulb as claimed in claim 1, further comprising a light-transmissible insulation film covering the light-transmissible conductive film.

4. The light bulb as claimed in claim 1, wherein the light-transmissible conductive film comprises nano-scale metal film, conductive compounds, transparent conductive adhesive, or transparent conductive oxide.

5. The light bulb as claimed in claim 1, wherein the light-transmissible conductive film is made of materials that only allow wavelengths of visible light spectrum to pass through.

6. The light bulb as claimed in claim 1, wherein the light bulb is an incandescent bulb, a light emitting diode light, an energy saving light bulb, or a fluorescent bulb.

7. A lighting fixture, comprising:

a lampshade; and

the light bulb as claimed in claim 1, disposed in the lampshade.

8. A lighting fixture, comprising:

a lampshade comprising an opening;

a cover covering the opening; and

a light-transmissible conductive film configured to be attached to the lampshade and the cover.

9. The lighting fixture as claimed in claim 8, wherein the lampshade and the cover comprise outer surfaces to which the light-transmissible conductive film is configured to be attached.

10. The lighting fixture as claimed in claim 8, wherein the lampshade and the cover comprise inner surfaces to which the light-transmissible conductive film is configured to be attached.

11. The lighting fixture as claimed in claim 8, further comprising a light-transmissible insulation film covering the light-transmissible conductive film.

12. The lighting fixture as claimed in claim 8, wherein the light-transmissible conductive film comprises nano-scale metal film, conductive compounds, transparent conductive adhesive, or transparent conductive oxide.

13. The lighting fixture as claimed in claim 8, wherein the light-transmissible conductive film is made of materials that only allow wavelengths of visible light spectrum to pass through.
