Abstract: A testing device for emergency lighting equipment including a main control unit and at least one control module, where each of the at least one control module is used to check operational readiness of an emergency lighting device, and the main control unit and the at least one control module are all connected to a network to form a control system for a smart phone or a building security monitoring system to perform a remote inspection operation on at least one aforementioned emergency lighting device via the network.

Abstract: An inspection device including a switch, a photo sensing element and a control module, where the switch is coupled between an alternating current power source and an emergency lighting device and is switched by the control module; the photo sensing element is used for sensing a lighting state of the emergency lighting device; and the control module is used to receive a command from a handheld device and transmit a detection result to the handheld device via a wireless communication.

Abstract: The present invention relates to a lens module for LED lamp, comprises a base installed with a first chamber and a second chamber opposite to the first chamber, the first chamber is able to be connected with a substrate, and at least one LED module is installed on the substrate; a first lens; and a second lens. With the mentioned structure, lights emitted by LED modules can be refracted by the first lens and the second lens for achieving the purpose of unifying lights. Moreover, the base, the first lens and the second lens are made of transparent material and formed with an injection molding means for lowering the production cost.

Abstract: The present invention relates to a light guiding structure, comprises: a printed circuit board for carrying following units; a light guiding column retained on the printed circuit board; at least one light-emitting member disposed on the printed circuit board and provided beside the light guiding column, and lights emitted by the light-emitting member can be refracted or reflected by the light guiding column for increasing the brightness of lateral light emitting.

Abstract: A thin laser module comprises a casing having a light emitting window on one side; a circuit board installed in the casing for containing components; a laser chip installed on the circuit board for emitting a primary laser and a secondary laser; a photodiode (PD) packaged by surface mount technology and installed on the circuit board and disposed at a side of the laser chip for receiving the secondary laser and producing a current; a control circuit installed on the circuit board and coupled to the photodiode for receiving the current to execute an automatic power control; and a lens installed in the casing for receiving the primary laser emitted from the laser chip and modulating the primary laser into parallel beams and transmitting the beams out from the light emitting window.
