LED illumination is with energy-efficient, and the long-life, good visual effect, controllability are strong etc., and plurality of advantages is replacing conventional light source.Along with the quickening of the superseded paces of incandescent lamp, LED illumination in the development of room lighting field rapidly.For compatible mutually with existing incandescent lamp wiring system, many LED illuminating lamps are integrated in AC-DC constant-current driving power supply and LED light source in a light fixture, and this lamp interface is consistent with incandescent lamp interface.
The shortcoming of prior art is: in order to reduce volume, between built-in AC-DC constant-current driving power supply electric elements, usually cannot meet Safety Approval; In order to reduce cost, built-in AC-DC constant-current driving power supply usually omits various filter elements, and the power supply making exists serious radiation, and performance also cannot meet the demands.Because indoor LED lamps is much that child can touch, the existence of this built-in AC-DC constant-current driving power supply can make this light fixture have potential safety hazard.If many bedside lamps exist radiation, for the injury of human body, be permanent.Such light fixture usually cannot Integrated intelligent control module in addition, cannot meet the demand of various light modulations.
Summary of the invention
In order to solve upper technology, state problem, the utility model proposes a kind of LED interior lighting system, make AC-DC driving power into external power supply, DC-DC constant-current driving power supply, intelligent object and LED light source are integrated in a light fixture, and this lamp interface is consistent with incandescent lamp interface, this utility model is compatible mutually with original incandescent lamp wiring system, and LED light fixture does not exist potential safety hazard, and can adapt to various light modulation demands.
The utility model comprises at least one AC-DC driving power, a plurality of DC-DC constant-current driving power supply and a plurality of LED light source.220V ac input end at least one AC-DC driving power in parallel, each AC-DC driving power input termination 220V alternating current, the input of output termination DC-DC constant-current driving power supply and intelligent object are for electrical input, and each AC-DC driving power output can a plurality of these DC-DC constant-current driving power supplies in parallel, the output termination LED light source of DC-DC constant-flow driver, intelligent object output pwm signal is controlled the output current size of DC-DC constant-current driving power supply.
The beneficial effects of the utility model:
In 1.LED light fixture, without AC-DC power supply, reduce the volume of light fixture, removed the potential safety hazard of light fixture.
Intelligent object capable freely changing in 2.LED light fixture, meets various customer demands.
3.LED lamp interface is consistent with conventional incandescent interface, meets user's use habit.
4.LED illuminator is compatible mutually with traditional incandescent lamp wiring system, economizes on resources.
5.LED illuminator can increase or reduce AC-DC driving power and LED light fixture number as required.
