## Abstract

The present invention is an on-camera flashlight, comprising a lower light holder and a top light holder freely rotatably connected to the lower light holder. A flashlight light source is mounted on the top of the top light holder. The light emitting diode and the flashlight light source are mounted on the on-camera flashlight, combined for ease of use. Two functions-in-one lighting device saves space, avoids overloading the camera, and makes it portable. Because the two light sources are set in combination, the cooperation and sequence of the two light sources are easier to control. As the light emitting diode is mounted on the top light holder which may freely rotate with respect to the lower light holder, the light emitting diode may also freely rotate. It is also convenient to adjust the light direction. Above features all remarkably facilitate operation and versatility of the on-camera flashlight.

## Claims

### Claim 1

An on-camera flashlight, comprising a lower light holder and a top light holder freely rotatably connected to the lower light holder; a flashlight light source disposed on a top portion of the top light holder; a high wattage light emitting diode disposed on a side of the top light holder facing a lens of the camera for providing fill light as a constant light source.

### Claim 2 (depends on 1)

The on-camera flashlight of claim 1, wherein a free rotating holder between the lower light holder and the top light holder is provided for connecting the lower light holder and the top light holder.

### Claim 3 (depends on 2)

The on-camera flashlight of claim 2, wherein the free rotating holder and the top light holder are connected by a pin structure.

### Claim 4 (depends on 1)

The on-camera flashlight of claim 1, wherein the on-camera flashlight includes a lithium battery for supplying power.

### Claim 5 (depends on 4)

The on-camera flashlight of claim 4, wherein the lower light holder includes a battery holder and the lithium battery is mounted within the battery holder.

### Claim 6 (depends on 5)

The on-camera flashlight of claim 5, wherein the lower light holder includes a cavity for housing the battery holder, and the battery holder is releasably mounted within the cavity, and the opening of the cavity includes a baffle capable of being opened and closed.

### Claim 7 (depends on 1)

The on-camera flashlight of claim 1, wherein a light emitting diode light holder capable of sliding up and down is mounted on the top light holder and is comprised of the high wattage light emitting diode mounted therein; wherein the top light holder comprises two sliding grooves that are symmetrically arranged and configured for the the light emitting diode light holder to slide up and down along the two sliding groves, so that the light emitting diode slides subtly adjust a lighting position.
