Abstract

The invention discloses a low-power illuminating system with LED (light-emitting diode) lamps. The system comprises an intelligent AC-DC (alternating current-direct current) power supply converter, the LED lamps, lamp switches and a parallel-type cable, wherein the input end of the intelligent AC-DC power supply converter is connected with an AC power supply; the low-voltage DC output end of the intelligent AC-DC power supply converter is connected with multiple LED lamps; the multiple LED lamps are connected in parallel; each LED lamp is connected with the lamp switch used for controlling the power-on and power-off of the LED lamp in series and then connected to the low-voltage DC output end of the intelligent AC-DC power supply converter; and each LED lamp is internally provided with a high-precision constant-current control circuit. The low-power illuminating system with the LED lamps can be used for solving the problems such as low power supply conversion efficiency, low system power factor, low constant-current control accuracy and the like in LED illumination application with lower cost and prolonging the service life of each LED lamp and the product safety.

Description

technical field [0001] The invention relates to a low-power LED lighting system. Background technique [0002] With the advancement of science and technology, lighting fixtures have developed from incandescent lamps to halogen lamps, high-pressure sodium lamps, fluorescent lamps, etc., and are constantly developing in the direction of energy saving, environmental protection, and low cost. The LED lighting fixtures that have emerged in recent years have the advantages of long theoretical life, energy saving and environmental protection, and large space for technological development, and their development momentum is rapid. The design brightness of low-power LED lamps within 30W is twice that of ordinary energy-saving lamps with the same power consumption, and the design life is more than five times that of ordinary energy-saving lamps. Most of the existing 220V or 110V AC power supply LED lamps are low-power lamps within 30W. These lamps are generally driven by a built-in hi...
