Abstract

A light module includes a plurality of LEDs coupled on a circuit board, a condenser unit including a plurality of condensers integrally coupled with each other and supported on the circuit board, and a plurality of converging lenses supported within the light cavities of said condensers respectively. Each LED is located at a focal point of the condenser and is located at a focal point of the converging lens. A first portion of light from the LED is directly project toward the converging lens and is diverged by the converging lens to parallelly project out of the condenser. A second portion of light from the LED is reflected by a light reflecting wall of the condenser to parallelly project out of the condenser. Therefore, the first and second portions of light form collimated light beams out of a light opening of the condenser.

Claims (19)

1. A light module, comprising:

a circuit board, a plurality of LEDs spacedly and electrically coupled on said circuit board for light generation;

a condenser unit comprising a plurality of condensers integrally coupled with each other and supported on said circuit board, wherein each of said condensers has a light cavity that said LED is supported therewithin, a light opening, and a light reflecting wall for reflecting the light from the LED toward said light opening; and

a plurality of converging lenses supported within said light cavities of said condensers respectively, wherein each of said LEDs is located at a focal point of said condenser and is located at a focal point of said converging lens, wherein a first portion of light from said LED is directly project toward said converging lens and is diverged by said converging lens to parallelly project out of said light opening of said condenser, wherein a second portion of light from said LED is reflected by said light reflecting wall of said condenser to parallelly project out of said light opening of said condenser, such that said first portion of light diverged by said converging lens and said second portion of light reflected by said light reflecting wall of said condenser form collimated light beams out of said light opening of said condenser, wherein each of said condensers further has a concave portion and a tubular portion, wherein said concave portion has an interior concave reflective surface that said LED is disposed at said concave portion of said condenser, wherein said tubular portion has an interior flat reflective surface that said light opening of said condenser is defined at said tubular portion of said condenser, wherein said tubular portions of said condensers are integrally coupled side-by-side.

2. The light module, as recited in claim 1 , wherein said tubular portions of said condensers are extended parallel with respect to said collimated light beams to enhance a light intensity thereof.

3. The light module, as recited in claim 2 , wherein each of said converging lenses comprises a lens body and a plurality of supporting legs raidally and downwardly extended from said lens body to couple at said light reflecting wall of said condenser so as to suspendedly support said lens body above said LED.

4. The light module, as recited in claim 3 , wherein said lens body is supported within said light cavity between said concave portion of said condenser and said tubular portion thereof.

5. The light module, as recited in claim 4 , further comprising a diffusing lens coupled at said light openings of said condensers for diffusing said collimated light beams.

6. The light module, as recited in claim 5 , wherein said diffusing lens has a plurality of convex lenses integrally formed at a surface of said diffusing lens that faces toward said LED for directionally diffusing said collimated light beams emitted by said LED.

7. The light module, as recited in claim 6 , further comprising a heat sink mounted at said circuit board for dissipating heat from said LEDs.

8. The light module, as recited in claim 7 , further comprising a casing, wherein said circuit board is supported by casing to house said LEDs therein.

9. The light module, as recited in claim 1 , wherein each of said converging lenses comprises a lens body and a plurality of supporting legs raidally and downwardly extended from said lens body to couple at said light reflecting wall of said condenser so as to suspendedly support said lens body above said LED.

10. The light module, as recited in claim 9 , wherein said lens body is supported within said light cavity between said concave portion of said condenser and said tubular portion thereof.

11. The light module, as recited in claim 1 , further comprising a diffusing lens coupled at said light openings of said condensers for diffusing said collimated light beams.

12. The light module, as recited in claim 11 , wherein said diffusing lens has a plurality of convex lenses integrally formed at a surface of said diffusing lens that faces toward said LED for directionally diffusing said collimated light beams emitted by said LED.

13. A light module, comprising:

a circuit board, a plurality of LEDs spacedly and electrically coupled on said circuit board for light generation:

a condenser unit comprising a plurality of condensers integrally coupled with each other and supported on said circuit board, wherein each of said condensers has a light cavity that said LED is supported therewithin, a light opening, and a light reflecting wall for reflecting the light from the LED toward said light opening; and

a plurality of converging lenses supported within said light cavities of said condensers respectively, wherein each of said LEDs is located at a focal point of said condenser and is located at a focal point of said converging lens, wherein a first portion of light from said LED is directly project toward said converging lens and is diverged by said converging lens to parallelly project out of said light opening of said condenser, wherein a second portion of light from said LED is reflected by said light reflecting wall of said condenser to parallelly project out of said light opening of said condenser, such that said first portion of light diverged by said converging lens and said second portion of light reflected by said light reflecting wall of said condenser form collimated light beams out of said light opening of said condenser, wherein each of said converging lenses comprises a lens body and a plurality of supporting legs raidally and downwardly extended from said lens body to couple at said light reflecting wall of said condenser so as to suspendedly support said lens body above said LED.
