Abstract: A portable lamp includes at least one lighting device and at least one handle body. The at least one handle body has two end portions and a turning space defined between the two end portions. The at least one lighting device is rotatably mounted between the two end portions of the at least one handle body. The at least one lighting device is selectively arranged to be maintained in the turning space of the at least one handle body as a folded state and rotated with the at least one handle body to have an included angle between the at least one lighting body and the at least one handle body as an unfolded state. The portable lamp can adjust the state of the at least one lighting device without moving the at least one handle body.

Abstract: A detachable battery rack includes a battery rack body, an anode end portion and a cathode end portion, wherein the battery rack body includes at least two rack panels which defines a battery cavity to install batteries, wherein the anode end portion, which is detachable mounted to the battery rack body, includes an anode conductive plate detachably coupled to the rack panels, and the cathode end portion, which is detachable mounted to the battery rack body, includes a cathode conductive plate detachably coupled to the rack panels, wherein the anode conductive plate and the cathode conductive plate are respectively provided at two opposite sides of the rack panels.

Abstract: The present invention discloses a gravity sensing flashlight, including a lamp holder, a cylindrical body and a tail cover, the lamp holder and tail cover being connected to the cylindrical body, a storage battery being provided in the cylindrical body, a switch being mounted on a side wall of the cylindrical body, a circuit board being mounted in the switch, a gravity sensor and an indicator light being provided on the circuit board; the lamp holder includes a shell cap, a shell body and a shell base which are in threaded connection to each other, a lens, a lens holder, an LED lamp bead and a lamp bead fixing frame being mounted in the shell body, a current chip controller being mounted on the lamp bead fixing frame, the current chip controller being connected to the LED lamp bead and the gravity sensor.

Abstract: An adjustable headlight includes a headband and an adjustable illumination device mounted on the headband. The adjustable illumination device includes a light source, a lens, a rotating shell, a first adjuster, a second adjuster, a tubular electrical conductive rack, and a base. The light source is electrically connected to the top end of the tubular electrical conductive rack. The lens is mounted on the front end of the rotating shell. The first adjuster is rotatably connected to the rotating shell. The second adjuster drives the tubular electrical conductive rack to be rotatably coupled with the first adjuster and the base. Rotating the rotating shell changes the distance between the light source and the lens, so as to achieve focus adjustment within the adjustable headlight without changing external length of the device. The device is adapted for being worn on the user's head in various circumstances.

Abstract: A portable illumination device includes a light source having a plurality of brightness levels and a touch control system, which is arranged for controlling an illumination of the light source, including a control system and a touch panel operatively connected to the control system, wherein the touch panel is configured for receiving a sliding touch operation, wherein the control system adjusts a current brightness level of the light source into an adjacent brightness level of the plurality of brightness levels in response to the sliding touch operation applied on the touch panel.
