Abstract

A novel light wherein the source of illumination is an array of light emitting diodes mounted on a printed circuit board. The board is contained within an impact resistant housing. Several different embodiments are disclosed for the housing, including injection molded and extruded variants.

Claims

1. An impact resistant trouble light, comprising:

a. a circuit board;

b. a plurality of light emitting diodes affixed to said circuit board in any desired pattern;

c. an enclosure tube, having a first open end and a second open end, surrounding and protecting said circuit board, wherein the portion of said enclosure tube lying over said plurality of light emitting diodes is transparent in order to allow the light produced by said plurality to escape said enclosure tube;

d. power means for providing electrical power to said plurality of light emitting diodes so as to cause them to produce light;

e. a grip, having an open end opening into a hollow interior, wherein said open end is placed over said first open end of said enclosure tube so that said grip frictionally engages said enclosure tube and closes said first open end of said enclosure tube; and

f. a cap, having an open end opening into a hollow interior, wherein said open end is placed over said second open end of said enclosure tube so that said cap frictionally engages said enclosure tube and closes said second open end of said enclosure tube;

2. An impact resistant trouble light as recited in claim 1, wherein the connection between said power means and said plurality of light emitting diodes includes current limiting means.

3. An impact resistant trouble light as recited in claim 1, wherein said enclosure tube, said grip, and said cap combine to form a water resistant seal around said circuit board.

4. An impact resistant trouble light as recited in claim 1 further comprising a hook for hanging said trouble light.

5. An impact resistant trouble light as recited in claim 1, wherein said circuit board further comprises a spacer ring positioned to engage said enclosure tube and hold said circuit board with respect to said enclosure tube.

6. An impact resistant trouble light, comprising:

a. an enclosure tube, divided into a first half and a second half, wherein said first half and said second half may be joined along a seam to form a hollow interior therebetween, and wherein said enclosure tube includes a transparent portion;

b. a circuit board placed within said hollow interior of said enclosure tube;

c. a plurality of light emitting diodes affixed to said circuit board in any desired pattern proximate said transparent portion of said enclosure tube; and

d. power means for providing electrical power to said plurality of light emitting diodes so as to cause them to produce light.

7. An impact resistant trouble light as recited in claim 6, wherein the connection between said power means and said plurality of light emitting diodes includes current limiting means.

8. An impact resistant trouble light as recited in claim 6, wherein said enclosure tube forms a water resistant seal around said circuit board.

9. An impact resistant trouble light as recited in claim 6, further comprising a gasket placed between said first and second halves of said enclosure tube so as to form a water resistant seal.

10. An impact resistant trouble light as recited in claim 6 further comprising a hook for hanging said trouble light.

11. An impact resistant trouble light as recited in claim 6, wherein said enclosure tube includes a grip, allowing said enclosure tube to be more easily grasped by a user.
