Its technical solution is:
A kind of automatic control LED illuminating lamp, comprise supply line, step-down drive circuit, rectification circuit, filter circuit and the led light source that can insert the 220V civil power, the step-down drive circuit inserts supply line, rectification circuit connects the step-down drive circuit, filter circuit connects rectification circuit, and led light source inserts on the output of filter circuit; On the circuit between step-down drive circuit and the rectification circuit, or supply line is provided with gravity switch.
Above-mentioned step-down drive circuit is the resistance-capacitance type reduction voltage circuit, and rectification circuit is a bridge rectifier, and filter circuit is the condenser type filter circuit, and gravity switch is the ball-type switch.
Above-mentioned step-down drive circuit, gravity switch, rectification circuit, filter circuit and led light source concentrate on the circuit board, and gravity switch is lateral attitude and is fixed on the circuit board, and the axis of gravity switch becomes 15 ° of angles with the board plane of circuit board.
The foregoing circuit plate is installed in the top cover inboard of box household electrical appliance with the attitude of tiling.
The present invention has following useful technique effect:
1, step-down drive circuit of the present invention carries out step-down to the 220V civil power that feeds, the electric current that reaches after the operating voltage enters rectification circuit, after the process rectification circuit becomes interchange into direct current, press through filter circuit filtering output galvanic current again, be the led light source power supply, take gravity switch such as ball-type switch can utilize the top cover opening angle of box household electrical appliance to realize more fully led light source energising or outage control.
2, the present invention is by taking the less ball-type switch of volume and weight, and each unit (device) parts are all focused on the circuit board, compact conformation, and volume is little, is convenient to be installed in the top cover inboard; In addition, gravity switch becomes 15 ° of angles to fix with the board plane of circuit board, circuit board can be installed in the top cover inboard of box household electrical appliance with the attitude of tiling, the angle that upwardly opens at top cover is during more than or equal to 30 °, the ball-type switch rotate thereupon and arrival and horizontal sextant angle more than or equal to 15 °, it becomes " ON " state from " OFF " state exchange, circuit turn-on, led light source is luminous to provide illumination, and top cover is closed downwards, in angle during less than 30 °, the ball-type switch also turn round thereupon and arrival and horizontal sextant angle less than 15 °, it becomes " OFF " state from " ON " state exchange, and circuit disconnects, and led light source extinguishes.
3, also to have energy consumption low in the present invention, and long service life is easy to characteristics such as installation, and is easy to utilize.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing and embodiment:
Fig. 1 is the electric principle schematic of one embodiment of the present invention.
Fig. 2 is that gravity switch in Fig. 1 mode and the installation site between the circuit board concern schematic diagram.
Situation when Fig. 3 is applied to horizontal refrigerator for the present invention, what illustrate is that the top cover of refrigerator is in opening.
Embodiment
In conjunction with Fig. 1 and Fig. 2, a kind of automatic control LED illuminating lamp, comprise supply line, step-down drive circuit 1, rectification circuit 2, filter circuit 3 and the led light source that can insert the 220V civil power, the step-down drive circuit inserts supply line, rectification circuit connects the step-down drive circuit, and filter circuit connects rectification circuit, and led light source inserts on the output of filter circuit, on the circuit between step-down drive circuit and the rectification circuit, or supply line is provided with gravity switch 4.Above-mentioned step-down drive circuit 1 is the resistance-capacitance type reduction voltage circuit, and rectification circuit 2 is a bridge rectifier, and filter circuit 3 is the condenser type filter circuit, and gravity switch 4 is the ball-type switch.Above-mentioned step-down drive circuit 1, gravity switch 4, rectification circuit 2, filter circuit 3 and led light source concentrate on the circuit board 5, and gravity switch 4 is lateral attitude and is fixed on the circuit board 5, and the axis of gravity switch becomes 15 ° of angles with the board plane of circuit board 5.
