6mm 8mm 10mm 12mm 16mm 19mm 22mm 25mm Waterproof Pilot lamp Signal LED indicator lights

An indicator light is mainly used on the circuit or mechanical equipment to monitor and alarm the operation status of the equipment.A device, that monitors the working or position status of circuits and electrical equipment by lamp. Indicator lamp is usually used to reflect the working state of the circuit (electric or non-electric), the working state of the electrical equipment (operation, shutdown or test) and the position state (closed or disconnected), etc.An indicator lamp used commonly colors are red, green, yellow, blue, white. Yellow means standby, green means normal operation, red means emergency stop.Color features are main color coordinates, the main wavelength, color purity, color temperature and color development, etc., the test methods are spectroscopic and integral method.High brightness blue, green and white products are sensitive to static electricity, in the use of the need to pay attention to the surge of static electricity will damage or damage the product, and the product contact with the workbench please use conductive pad through the resistance ground; The tip of the soldering iron must be grounded; Ion generators are recommended.

The electric characteristic parameters of LED include forward current, forward voltage, reverse current and reverse voltage. This test is generally carried out by using voltage ammeter under the condition of constant current and constant voltage source. The parameters of maximum allowable forward voltage, forward current and reverse voltage and current can be obtained by testing the electrical characteristics of LED. In addition, the optimal working electrical power value of LED can also be obtained.
