Abstract

Provided is a switch which can perform touch and infrared ray remote control through non-conducting materials to perform dimming control of a LED. In an insulating casing, a power supply unit, a sensitivity capacitor, a remote control receiving terminal, a central control module IC, a touch terminal and an NMOS output control terminal are in connection. Midway dimming and memory functions of touch dimming, cycle dimming and long press cycle dimming can be realized by human body touch; a remote control part realizes ON/OFF, full lightening, ninth-level brightness, slow flash functions and brightness adjustment.

Description

LED touching telecontrol dimmer switch

Technical field:

The utility model relates to the LED desk lamp switch, especially can be simultaneously at non-conducting material touches and infra-red remote control carries out light modulation to LED switch.

Background technology:

At present; Known dimmer switch is traditional knob mechanical light modulation switch and touches dimmer switch and remote control switch; Major part is used in incandescent lamp and fluorescent lamp; But the dimmer switch of this type can not directly carry out brightness adjustment control to LED, must mix just tunable optical of LED tunable optical power supply, not only increases finished product but also can significantly reduce life-span of LED.The electrifying startup time is long, unstable properties, and flicker can appear in LED in low-light level, is not with memory function, and is high pressure, and is abnormally dangerous, have potential safety hazard, and the user uses inconvenience.

The utility model content:

In order to make the convenient safer use dimmer switch of user; The utility model provides the LED touching telecontrol dimmer switch of a kind of dc low-voltage 36V; Can provide LED and touch electrodeless light modulation and two kinds of application of remote control light modulating, the 0.5 second system's fast and stable that powers on, the touching telecontrol operation can be in the electrodeless light modulation of light 0%～100% circulation; Remote control contains 9 grades of brightness to be selected, easy to operate strong durable.

The utility model solves the technical scheme that its technical problem adopted:

A kind of LED touching telecontrol dimmer switch; In insulation crust (1), the switch that the electric power system (7) that touch sheet (2), sensitivity electric capacity (3), receiver of remote-control sytem (4), NMOS control end (5), central processing IC module (6) and electric capacity and integrated package constitute is connected and is furnished with remote controller (8).

The utility model is a by low pressure 0～36V direct current supply, controls the novel switched of electrodeless dimming function through a capacitance touch induced key and 9 grades of remote controls.In insulation crust, form the induction of signal end by touch sensible end and infra-red remote control receiving terminal, constitute the power pack of switch I C by electric capacity, resistance and integrated circuit, between VDD and VSS, use capacitor filtering, the wiring filter capacitor is near the IC controller.Capacitor C S is the sensitivity control capacitance, uses NPO material electric capacity, to reduce the influence that sensitivity is produced because of variations in temperature.Sensitivity electric capacity will be away from power component, heater etc. when wiring.When covering copper,, cover copper, below induction bonding pad, near the IC, avoid covering copper as far as possible in order to avoid produce interference with 20% netted ground connection Copper Foil because near the touch pad radio signal or high tension apparatus goods magnetic field are arranged.The induction bonding pad rule increases induction sensitivity.Touching dimming function is through capacitance touch induction end induction electrode, realizes touching light modulation, circulation light modulation, long light modulation midway by the circulation light modulation, memory function; The remote control control section is realized ON/OFF, bright, 9 grades of brightness entirely, is dodged functions such as function, brightness regulation slowly.

Description of drawings:

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Fig. 1 is the circuit theory diagrams of the utility model.

Embodiment:

In Fig. 1, the power unit 1,2 that is made up of whole switch C1, C2, C3, C4 electric capacity and integration module links to each other with the TSP end of IC for touching sheet; 3 is that infrared receiver links to each other with the IR of IC, output PWM control NMOS, the CSN of CS one termination IC; The CSP of one termination IC; For reaching good touch effect, the standard value of CS is 4.7nf, please be controlled at 3.3nf～8.8nf.

Claims

1. LED touching telecontrol dimmer switch; In insulation crust (1), the switch that the electric power system (7) that touch sheet (2), sensitivity electric capacity (3), receiver of remote-control sytem (4), NMOS control end (5), central processing IC module (6) and electric capacity and integrated package constitute is connected and is furnished with remote controller (8).
