Abstract: The invention relates to the technical field of lighting, more particularly to a LED street light that includes a main body and a support arm connected to the main body. A female joint is provided at one end of the support arm close to the main body. A male joint is provided at one end of the main body close to the support arm. When installing the LED street light, the male joint and the female joint are mutually inserted to supply power to the main body, without arranging the circuits in the LED street light before installation, which greatly simplifies the installation process and reduces the installation time and the installation difficulty. In addition, due to the reduction of the installation time and installation difficulty, the safety hazards caused by the installation of the LED street lights can also be prevented, and safety is thus improved.

Abstract: A plant lamp includes a radiator member, a power box, and lamp beads. The radiator member includes an upper surface, a lower surface opposite to the lower surface, and side surfaces connected between the upper surface and the lower surface. The power box and the lamp beads are arranged on the upper surface and the lower surface respectively. The power box is electrically connected to the lamp beads. The plant lamp further includes at least one power socket electrically connected to the power box and a wiring module. At least one side surface of the radiator member is provided with a fixing seat, the fixing seat defines a slot capable of engaging with a quick lock. When the two plant lamps are to be assembled, the fixing seats of the two plant lamps close to each other, and the quick lock runs through the slots of the fixing seats of the two plant lamps to lock the two plant lamps together.

Abstract: A system and a method for measuring the focus position of high-power laser are disclosed. The system includes a micro-controller, a stepping motor driver, an electric lifting platform, an electric rotation platform, a metal target, a displacement sensor, a photoelectric sensor and an ADC module. The system uses a laser to irradiate the metal target, which is moved upward and downward, to obtain the best ablation point through the ultraviolet radiation emitted on it.

Abstract: The present invention discloses a high bay light, including a cover plate, an illumination module, a lens module and a mounting mechanism. The lens module is removably mounted to the high bay light, providing convenience and saving costs to users when the floor plans are updated or the purpose of the building is changed wherein the high bay light is installed.
