Abstract: A waterproof lamp includes a housing having an inner cavity for receiving a lamp body, and at least one end forming a wiring opening for drawing out wiring; a wiring end cover is sealed on the wiring opening and can be threaded out; a first sealing member is formed between the wiring end cover and the interior surface of the housing and engages with the wiring end cover for the wire to pass through; the wiring end cover includes a fixed cover and a movable cover, the movable cover is detachably coupled to the outer side of the fixed cover; and a second sealing member is disposed between the movable cover and the fixed cover. The first sealing member of the waterproof lamp is filled with liquid and can be solidified to form a waterproof rubber layer sealed between the first sealing member and the inner wall of the housing.

Abstract: An intelligent power supply includes: constant current/constant voltage module; dimming control module which is located at a rear end of the constant current/constant voltage module and is electrically connected thereto; switching circuit for electrically connecting the constant current/constant voltage module and load, which is controlled by the dimming control module; the intelligent power supply further including voltage sampling module disposed between the constant current/constant voltage module and the dimming control module; and the power supply voltage of the voltage sampling module is provided by the constant current/constant voltage module, and the dimming control module detects the voltage signal of the sampling resistance of the voltage sampling module in real time; the operating power of the dimming control module is provided by the power supply voltage of the voltage sampling module.

Abstract: A showcase lamp includes a lamp body having a light-emitting module therein, and the lamp body is externally provided with a first terminal draw out from the light-emitting module; and at least one upright stanchion, the upper end of the upright stanchion supports the lamp body, and the lower end of the upright stanchion can be detachably fixed on the showcase to be installed; wherein the upright stanchion is a hollow rod, and the upper end of the at least one upright stanchion is provided with a second terminal for communicating with the first terminal, and the lower end of the upright stanchion is provided with a third terminal for connecting external power supply or for interconnecting with adjacent lamps, the upright stanchion is built-in with wires connecting the second terminal and the third terminal.
