Abstract

An LED lamp set for enhancing illumination and eliminating ghost images includes a lamp shade, a diffusion membrane and a circuit board. The lamp shade has a plurality of light cups each having a housing chamber to hold at least one LED. The housing chamber has an aperture at the bottom run through by the LED to form electric connection with the circuit board and an opening remote from the aperture to define a light output surface. The diffusion membrane covers the light output surface and is made of a transparent material and includes a plurality of transparent bumps on the surface. The circuit board is located below the lamp shade. Through the concave shape of the light cups and repetitive reflection of the bumps, light can be condensed to avoid scattering and loss. Moreover, as the light is greatly and uniformly condensed, ghost images can be eliminated.

Claims (13)

1. An LED lamp set for enhancing illumination and eliminating ghost images, comprising:

a lamp shade including a plurality of light cups each being formed in a concave shape to form a housing chamber to hold at least one light emitting diode, the housing chamber including an aperture at the bottom thereof and an opening remote from the aperture to define a light output surface;

a diffusion membrane which is located on the lamp shade to cover the light output surface and is made of a transparent material and includes a plurality of transparent bumps on the surface thereof; and

a circuit board located below the lamp shade to form electric connection with the light emitting diode which runs through the aperture,

wherein the opening is formed at a length equal to a distance from the opening to the aperture.

2. The LED lamp set of claim 1 further including a light condensing hood to encase the light emitting diode.

3. The LED lamp set of claim 1 , wherein each light cup includes a plurality of light reflection protrusive traces inside.

4. The LED lamp set of claim 1 , wherein the lamp shade includes a plurality of support brackets on an outer side thereof, each of the plurality of support brackets fastening to the circuit board through a screw.

5. The LED lamp set of claim 1 , wherein the circuit board includes an upper surface connecting to the light emitting diode and a lower surface.

6. The LED lamp set of claim 5 , wherein the circuit board includes one set of radiation fins on the lower surface.

7. The LED lamp set of claim 1 ; wherein the lamp shade is plated with aluminum.

8. The LED lamp set of claim 1 , wherein the lamp shade includes a plurality of opaque reflective mirror surfaces to separate the light cups.

9. The LED lamp set of claim 1 , wherein the housing chamber includes a reflective surface proximate the opening and perpendicular to the light output surface.
