Light emitting diode matrix lamp optical system

Abstract

The invention relates to a light emitting diode matrix lamp optical system. An AC / DC rectifier is arranged for converting an alternating current to a direct current and providing the current to a switch type voltage-reducing integrated circuit; the switch type voltage-reducing integrated circuit is arranged for reducing the voltage of the inputted current to be a working voltage of rechargeable batteries and providing a constant current so as to charge the rechargeable batteries; the rechargeable batteries can provide a power source to the light emitting diode when the power is cut off; a touch switch is arranged for automatically open the switch type voltage-reducing integrated circuit after the power is cut off; the switch type voltage-reducing integrated circuit increases the voltage of the rechargeable batteries to be an LED working voltage and outputs the voltage to a voltage-stabilizing circuit; and the voltage-stabilizing circuit is arranged for converting the voltage input by the switch type voltage-reducing integrated circuit to a stable direct current power source and providing to the light emitting diode matrix so as to illuminate the light emitting diode matrix. The system of the invention can be applied to the illumination devices in public and plays a positive role in decreasing the burden on society in the peak period of using electrify in city and lowering the cost.

Description

Technical field [0001] The invention relates to a device in the field of lighting technology, in particular to a light emitting diode (LED) array lighting optical system. Background technique [0002] In real life, people are most inseparable from lighting, and most of the lighting appliances used today are incandescent lamps and fluorescent energy-saving lamps. As a new light source LED that is energy-saving and environmentally friendly, it is rarely used. In the United States, Europe, Japan and other developed countries, LED as a new light source has developed by leaps and bounds in recent years. Their luminous flux can reach more than 80 lumens, which can completely replace incandescent lamps and fluorescent lamps. [0003] Semiconductor diodes are a type of commonly used electronic component diodes. Light-emitting diodes are also called emitting diodes. They are a device that can convert electrical energy into light energy and are solid-state light sources. Since the first li...
