Abstract

An LED utility light has a hollow housing with an upper light portion and a lower handle portion, the housing being formed by a rear shell and a front shell with a lens aperture formed therein. An LED circuit board assembly disposed in the housing has an array of LEDs arranged in rows facing the lens opening. A reflector member is mounted between the circuit board assembly and the lens opening and has a plurality of light apertures formed therein corresponding to the array with each LED being visible through an associated one of the light apertures, the reflector member having a reflective front surface. A lens member is mounted in the lens opening for passing light generated by the LEDs.

Claims

1. An LED utility light, comprising:

a hollow housing having an upper light portion and a lower handle portion, said light portion having a lens aperture formed therein;

at least one cushion attached to said housing and exposed at an exterior surface of said housing;

an LED circuit board assembly disposed in said housing, said circuit board assembly including a plurality of LEDs arranged in a predetermined may and facing said lens opening;

a reflector member mounted between said circuit board assembly and said lens opening, said reflector member having a plurality of light apertures formed therein corresponding to said array with each of said LEDs being visible through an associated one of said light apertures; and

a lens member mounted in said lens opening for passing light generated by said LEDs,

wherein at least one projection is formed on said reflector member and at least one groove is formed in said lens member, said at least one projection and said at least one groove cooperating to align said reflector member with said lens member.

2. The utility light according to claim 1 wherein said at least one cushion has at least one attachment finger engaging a cutout in said housing.

3. The utility light according to claim 1 wherein said at least one cushion is one of an upper cushion mounted on said light portion and a handle cushion mounted on said handle portion.

4. The utility light according to claim 1 including a hook member rotatably attached to said housing.

5. The utility light according to claim 1 including at least one support leg extending from said reflector member and engaging a support pin extending from an inner surface of said housing.

6. The utility light according to claim 1 wherein said LEDs are arranged in rows of three LEDs each.

7. The utility light according to claim 1 wherein said plurality of LEDs includes at least thirty LEDs.

8. The utility light according to claim 1 wherein said light apertures are cone shaped.

9. The utility light according to claim 1 wherein said reflector member has a reflective front surface.

10. The utility light according to claim 1 wherein said lens member has a plurality of focusing portions formed thereon facing said LEDs for focusing light generated by said LEDs.

11. An LED utility light, comprising:

a hollow housing having an upper light portion and a lower handle portion, said housing being formed by a rear shell and a front shell, said front shell having a lens aperture formed in said light portion;

an LED circuit board assembly disposed in said housing, said circuit board assembly including a plurality of LEDs arranged in a predetermined array and facing said lens opening;

a reflector member mounted between said circuit board assembly and said lens opening, said reflector member having a plurality of light apertures formed therein corresponding to said array with each of said LEDs being visible through an associated one of said light apertures;

at least one support leg extending from said reflector member and engaging a support pin extending from an inner surface of said housing; and

a lens member mounted in said lens opening for passing light generated by said LEDs.

12. The utility light according to claim 11 including a pair of cushions attached to opposite sides of said light portion of said housing.

13. The utility light according to claim 11 including pair of handle cushions mounted on opposite sides of said handle portion.

14. The utility light according to claim 11 including a hook member rotatably attached to said housing.

15. The utility light according to claim 11 including at least one projection formed on said reflector member and at least one groove formed in said lens member, said at least one projection and said at least one groove cooperating to align said reflector member with said lens member.

16. The utility light according to claim 11 wherein said LEDs are arranged in at least ten rows of three LEDs each.

17. An LED utility light, comprising;

a hollow housing having an upper light portion and a lower handle portion, said housing being formed by a rear shell and a front shell, said front shell having a lens aperture formed in said light portion;

at least one handle cushion mounted on said handle portion and exposed at an exterior surface of said handle portion;

an LED circuit board assembly disposed in said housing, said circuit board assembly including a plurality of LEDs arranged in a predetermined array and facing said lens opening;

a reflector member mounted between said circuit board assembly and said lens opening, said reflector member having a plurality of light apertures formed therein corresponding to said array wit each of said LEDs being visible through an associated one of said light apertures, said reflector member having a reflective front surface; and

a lens member mounted in said lens opening for passing light generated by said LEDs,

wherein at least one projection is formed on said reflector member and at least one groove is formed in said lens member, said at least one projection and said at least one groove cooperating to align said reflector member with said lens member.
