An alternating current power supply apparatus sends an alternating current power to a dimmer. The dimmer dims the alternating current power to fetch a dimmed power. The dimmer sends the dimmed power to a rectification unit. The rectification unit rectifies the dimmed power to fetch a rectified power. The rectification unit sends the rectified power to an integration sampling unit and a light emitting diode. The integration sampling unit integrates, samples and converts the rectified power to fetch an integration voltage signal. The integration sampling unit sends the integration voltage signal to a voltage-to-current control conversion unit. The voltage-to-current control conversion unit converts the integration voltage signal to fetch a driving current signal to drive the light emitting diode. The driving current signal is constant, so that the light emitting diode is not blinking.

Illumination device

A buckle includes a first fastener and a second fastener. The second fastener has two hooks. The first fastener includes a socket, a locking piece disposed in the socket, and two first locking portions formed on the socket for mating with the hooks. The locking piece is slidingly connected in the socket to cooperate with the second fastener. When the first fastener is engaged with the second fastener, the locking piece enters the second fastener to restrict the movement of the second fastener, so that the second fastener cannot be released unless the locking piece is removed from the second fastener and the hooks of the second fastener are pressed. Thus, the second fastener can be released only when the locking piece is moved, thereby preventing a problem that the second fastener may be separated from the first fastener when the hooks of the second fastener are incautiously pressed. A user has to move the locking piece with one hand and presses the hooks with another hand. Thus, such an action performed by two hands is uneasy for a child, thereby generating a safety effect.

A combined display frame and lamp system is provided. This system includes a display frame; a mount fastened to the display frame; and, a lamp holder secured relative to the display frame through a connecting mechanism coupled to the mount. The system also includes a back support pivotally coupled to the mount for supporting the mount and the display frame on a support surface.

Picture frame and lamp arrangement

A tripod including a tripod head supported on tripod legs and formed of two symmetrical half shells and defining a ball socket between the half shells, a camera platform adapted for holding a camera and having a ball at the bottom mounted in the ball socket of the tripod head, a hexagon nut mounted within a hexagonal hole in one half shell of the tripod head, a lock screw inserted through a respective mounting hole in each half shell of the tripod head and threaded into the hexagon nut and then screwed up with a cap nut, wherein turning the lock screw in one direction causes the two half shells of the tripod head to be released from each other for permitting the ball of the camera platform to be turned to the desired angle; turning the lock screw in the reversed direction causes the ball of the camera platform to be firmly retained in the ball socket of the tripod head in position.

Angularly positionable camera tripod

A type of lamp track clamp structure, comprising a main unit, first fixing pieces, second fixing pieces, clamp pieces and conductive screws, the first fixing pieces and the second fixing pieces are installed in the main unit, the two clamp pieces are fitted on the front and back sides of the main unit, the conductive screws are screwed through the clamp pieces and the main unit to compose a lamp track clamp structure; the above configuration is so designed that the track clamp may involve a universal purpose to significantly reduce production costs and enable convenient operation.
