Abstract

The utility model discloses a light modulator comprising a connecting terminal, a touch panel and a circuit board in the touch panel, wherein two ends of the circuit board are respectively connected with a head lamp and a power supply by the connecting terminal; the circuit board comprises a detecting and sampling circuit, an AC-DC conversion circuit, a control loop, a remote control loop, a protection loop and a metallic oxide field-effect tube, wherein a signal output by the detecting and sampling circuit connected with the head lamp is output to two ends of the AC-DC conversion circuit; after a direct current working voltage signal produced by the AC-DC conversion circuit is output to the control loop and the protection loop, a control signal is produced by being processed by the integrated software of a touch zone in the touch panel to be output to the metallic oxide field-effect tube. The utility model has various control modes, can control various loads, can effectively overcome the technical problems of single regulation mode and single load control of the traditional light modulator, has simple circuit and is easy to realize.

Description

A kind of dimmer

Technical field

The utility model relates to a kind of illuminating product, specifically, is a kind ofly can utilize hand to touch or the RF remote-controlled dimmer that reaches switch, regulates lighting brightness.

Background technology

Dimmer is widely used in the hotel, the hotel, meeting room, more began in recent years to popularize to family, except purpose of energy saving, the more important thing is, it can be according to the power and the different demands of user to brightness of extraneous light, indiscriminately ad. as one wishes regulate the brightness of lighting, thereby build different ambient brightnesss, bring great convenience to the user, mostly traditional dimmer is knob, utilize potentiometer to come manual adjustments brightness, the load that can regulate also is confined to resistive load such as incandescent lamp etc., makes troubles to the user.

The utility model content

For solving the problem that prior art exists, the utility model proposes a kind of dimmer, it has multiple control modes, can control multiple load, and the regulative mode that can effectively overcome present traditional dimmers is single, the technical problem that control load is single.

The utility model is solved by the following technical programs:

A kind of dimmer; comprise binding post; touch panel; circuit board in the touch panel; described circuit board two ends by binding post respectively with illuminating lamp; power supply connects; described circuit board comprises the detection sample circuit; ac-dc converter circuit; control loop; remote control circuit; the protection loop; metal-oxide-semiconductor field effect t; the signal of the detection sample circuit output that is connected with illuminating lamp outputs to the ac-dc converter circuit two ends; and the direct-current working volts signal that produces by ac-dc converter circuit outputs to control loop; the protection loop produces control signal after the touch area integrated software in the described touch panel is handled the back, outputs to metal-oxide-semiconductor field effect t.

Because adopt above technical scheme, the utility model has multiple control modes, can control multiple load, the regulative mode that can effectively overcome present traditional dimmers is single, the technical problem that control load is single, and the utility model circuit is simple, easily realizes.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is elaborated:

Fig. 1 is the utility model circuit theory diagrams.

Among the figure: 1, detect sample circuit; 2, ac-dc converter circuit (AC-DC); 3, control loop; 4, remote control circuit; 5, the protection loop; 6 touch area integrated softwares; 7, metal-oxide-semiconductor field effect t (MOSFET)

Embodiment

The utility model is described in further detail with reference to the accompanying drawings below:

A kind of dimmer; comprise binding post; touch panel; circuit board in the touch panel; as shown in Figure 1; the circuit board two ends by binding post respectively with illuminating lamp 9; power supply 8 connects; circuit board comprises detection sample circuit 1; ac-dc converter circuit (AC-DC) 2; control loop 3; remote control circuit 4; protection loop 5; metal-oxide-semiconductor field effect t 7; the signal of detection sample circuit 1 output that is connected with illuminating lamp outputs to ac-dc converter circuit (AC-DC) 2 two ends; and the direct-current working volts signal that produces by ac-dc converter circuit (AC-DC) outputs to control loop 3; protection loop 5 produces control signal after the touch area integrated software 6 in the described touch panel is handled the back; output to metal-oxide-semiconductor field effect t (MOSFET) 7; control metal-oxide-semiconductor field effect t (MOSFET) 7, thereby the switch and the light modulation of control light fixture.

1, the differentiation of load type:

Detect the classification that sample circuit 1 is used for judging load, thereby take different dimming modes, specifically, when load is incandescent lamp or high-pressure halogen lamp, or during electronic transformer (afterwards wearing 12V low pressure halogen lamp), system makes judgement, and the dimming mode of cut before adopting, and obtains good dimming effect; And when load was inductive transformer (afterwards wearing 12V low pressure halogen lamp), system made judgement, and adopted the dimming mode of back cut, also can obtain good dimming effect;

2, touch the realization of control:

State-of-the-art touching technique is partly adopted in the manual light modulation of the utility model, can be 1 touch, and the realization short time is pressed switch, for a long time by light modulation; Also can be that nearly 4 multidigit touches, the user can certain arbitrarily lamplight brightness be set to corresponding with certain key, directly touch one of them button, can make light fixture directly arrive certain default brightness, this for scene control easily, shown in Figure 1 is the situation of 1 touch area, and the short time touches this zone, then will control the open and close (hocketing) of light fixture; Long-time this zone that touches then will lighten or dim light fixture (hocketing)

3, the realization of distant control function:

Remote control circuit 4 adopts the special-purpose radio-frequency transceiving chip to realize receiving from another product-control of remote controller signal, can realize that then wireless remote control controls the open and close and the light modulation of this light fixture, this at first will pass through sign indicating number, join in the remote controller, by the respective keys above the remote controller, for example open then, close, light modulation realizes the switch and the light modulation of control light fixture at last.

But above-mentioned embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope that this patent comprises.
