Abstract

A portable flashlight apparatus is provided that is lightweight and compact to provide enhanced illumination in an ambient environment when placed in one of a plurality of operating modes. The portable flashlight apparatus includes a base housing defining an interior space and which includes structurally defined regions that include a front housing region, a rear housing region, an intermediate housing region extending between the front housing region and the rear housing region and an end cap that closes the interior space at the rear housing region. A light module includes a first light source operable to emit illuminating light, a second light source operable to emit laser light, and a third light source operable to emit illuminating light. A magnet are arranged at the rear face of the end cap, and is operable to magnetically bias the base housing on a working surface or support surface having magnetic properties.

Claims (50)

1. A portable flashlight apparatus, comprising:

a base housing defining an interior space, the base housing including structurally defined regions that include a front housing region, a rear housing region, an intermediate housing region extending between the front housing region and the rear housing region and an end cap that closes the interior space at the rear housing region;

a light module arranged at the front housing region and operable between a plurality of operating modes, the light module including a first light source operable to emit illuminating light from the front housing region in a direction parallel to a longitudinal axis of the base housing, and a second light source operable to emit illuminating light from the front housing region in a direction perpendicular to the longitudinal axis of the base housing;

a magnetic element arranged at the rear face of the end cap, and operable to magnetically bias the base housing on a working surface or support surface having magnetic properties; and

a holder in the interior space defined by the base housing;

wherein the light module is mounted on the holder;

wherein the first light source faces a first direction;

wherein the second light source faces a second direction, perpendicular to the first direction;

wherein the front housing region has a first outer perimeter, the rear housing region has a second outer perimeter, and the intermediate housing region has a third outer perimeter that is less than the first outer perimeter and the second outer perimeter; and a power charging port arranged centrally on an outer sidewall surface of the intermediate housing region facing in the second direction.

2. The portable flashlight apparatus of claim 1 , wherein the first light source comprises one or more LEDs.

3. The portable flashlight apparatus of claim 1 , wherein the second light source comprises a plurality of LEDs.

4. The portable flashlight apparatus of claim 3 , wherein the color temperature of light emitted by the LEDs of the second light source is 4,500 K.

5. The portable flashlight apparatus of claim 1 , further comprising a rechargeable power source arranged at the intermediate housing region;

wherein the rechargeable power source is mounted on a printed circuit board.

6. The portable flashlight apparatus of claim 5 , wherein the rechargeable power source comprises a rechargeable battery, and

wherein the printed circuit board extends along an axis parallel to the longitudinal axis of the base housing; and

wherein the printed circuit board is longer than the rechargeable battery.

7. The portable flashlight apparatus of claim 6 , wherein the power charging port is operable to facilitate a total charging time of 60 minutes to reach a full charged state of the rechargeable battery.

8. The portable flashlight apparatus of claim 1 , further comprising a user interface (UI) arranged on an outer sidewall surface of the front housing region.

9. The portable flashlight apparatus of claim 1 , further comprising a hook;

wherein when the hook is in the stowed position, the end cap projects farther rearwardly than the hook.

10. The portable flashlight apparatus of claim 1 , further comprising a clip member extending longitudinally along an outer sidewall surface of the rear housing region and an outer sidewall surface of the intermediate housing region.

11. A portable flashlight apparatus, comprising:

a base housing defining an interior space, the base housing including structurally defined regions that include a front housing region, a rear housing region, an intermediate housing region extending between the front housing region and the rear housing region and an end cap that closes the interior space at the rear housing region;

a light module arranged at the front housing region and operable between a plurality of operating modes, the light module including a first light source operable to emit illuminating light from the front housing region in a direction parallel to a longitudinal axis of the base housing, and a second light source operable to emit illuminating light of at least approximately 300 lumens from the front housing region in a direction perpendicular to the longitudinal axis of the base housing; and

one or more magnetic elements, arranged at the rear face of the end cap, and operable to magnetically bias the base housing on a working surface or support surface having magnetic properties;

wherein the first light source comprises a first LED on a first printed circuit board;
