Abstract

At present, various finished products of delay illuminating lamp control devices in the market have the general problems of complicated circuits, multiple used elements, high circuit failure rate, high manufacturing cost and the like. In order to overcome the defects of the conventional finished products of delay illuminating lamp control switches in the market, the invention provides a concise incandescent lamp delay circuit consisting of a three-pin PTC demagnetizing thermistor for color TV color picture tubes, an AC relay and a button switch. The incandescent lamp delay circuit is completely power-off after an incandescent lamp is turned off, so standby energy consumption is eliminated. Compared with the conventional delay illuminating control switches in the market, the incandescent lamp delay circuit has the characteristics of concise structure of the delay control circuit, less used elements, reliable circuit performance, low manufacturing and development cost and the like, and is suitable for illuminating delay control of various incandescent lamps in households or public places; and a delay illuminating lamp has obvious power-saving effect.

Description

Make delay illuminating lamp with the PTC element

Technical field

The invention belongs to electronic technology, power-saving technique field, relate to a kind of with PTC element making delay illuminating lamp.

Background technology

At present, integrated circuit was overlapped to form delay control circuit when common illumination delay control circuit adopted 555 bases more, promoted direct current relay adhesive or release then, the light on and off of control incandescent lamp; Also there be a variety ofly to be overlapped to form delay circuit lighting or extinguish by one-way SCR or bidirectional triode thyristor control incandescent lamp with discrete electronic component.

The various finished products of delay illuminating lamp control ubiquities in market a series of problems such as the components and parts that use in circuit structure more complicated, the circuit are more, the fault rate is higher, cost of manufacture is higher.

For the deficiency that overcomes on the market existing finished products of delay illuminating lamp control and some defectives of existence, be necessary to research and develop a kind of circuit constitute simple and direct, the components and parts consumption is few, the reliable illuminating lamp delay control circuit of circuit working production program.

Summary of the invention

Goal of the invention: compare with having the illuminating lamp overrun control on the market, have characteristics such as the delay control circuit structure is simple and direct, the components and parts consumption is few, circuit performance reliable, the making development cost is low.

Technical scheme: utilize colour TV to be combined into simple incandescent lamp delay circuit with PTC thermal sensitivity field-discharge resistance, AC relay and push-button switch.

Beneficial effect: circuit is very simple, and it is easy especially not only make, and incandescent lamp extinguish after outage fully, no standby power consumption, thereby very energy-conservation.It is little that the illumination time-delay mechanism has a volume, can composite design among 86 type electrical standard panels, be applicable to the various incandescent lamps time-delay illumination controls of house or public place, delay illuminating lamp has tangible power savings, and popularization, the universal use have bigger meaning.

Description of drawings

Accompanying drawing is to make delay illuminating lamp circuit working schematic diagram with the PTC element.

In the accompanying drawing circuit tripod PTC element 1., 2. pin R1 is an assistant heating resistance, the PTC element 2., 3. pin R2 is the thermal sensitivity field-discharge resistance; J is the 220V AC relay.

Embodiment

Accompanying drawing and description of drawings to specifications, below embodiment be that example is further described correlation technique of the present invention with tripod thermal sensitivity field-discharge resistance.

Circuit is formed: make the delay illuminating lamp circuit with the PTC element and be made up of with 4 kinds of components and parts such as PTC thermal sensitivity field-discharge resistance, AC relay J and incandescent lamp H push-button switch AN, colour TV.

Operation principle: the R2 internal resistance in the tripod PTC thermal sensitivity field-discharge resistance under the normal temperature only has 27 Ω.In the time need turning on light on foot night, press the button switch AN, so by behind the AN switch, directly powering to the load through R2, the 220V alternating current make incandescent lamp H luminous.Meanwhile, be connected to the also adhesive of 220V AC relay J at incandescent lamp H two ends, its normally opened contact J-1 connects and makes the closing of circuit self-locking, and bulb H keeps lighting.

After bulb H energising illumination time-delay a period of time, the PTC element in galvanization since wherein R2 and R1 heat up gradually, when internal temperature arrives Curie point, the resistance of PTC increases sudden change and the approaching open circuit of resistance, make incandescent lamp H extinguish at once, the coil of relay J also discharges because of dead electricity makes normally opened contact J-1, and the circuit self-locking state is removed, and bulb H comes back to and extinguishes holding state.When pressing the button switch AN again, circuit repeats the above-mentioned course of work again.

With the annexation between the delay illuminating lamp components and parts of PTC element making

Circuit is formed: make the delay illuminating lamp circuit with the PTC element and be made up of with PTC thermal sensitivity field-discharge resistance, AC relay J and incandescent lamp H push-button switch AN, colour TV.

The normally opened contact J-1 two ends of the two ends of push-button switch AN and AC relay J and connect after the L end of a termination civil power live wire, the 2. pin of its another termination PTC element; The two ends of AC relay J coil are connected to the 3. pin of the termination PTC element behind the two ends of incandescent lamp H, the N end that together connects the civil power zero line after 1. pin links to each other of its other end and PTC element.

Components and parts are selected and are made:

The model of three end PTC thermal sensitivity field-discharge resistances in the circuit is 27RM, or the colour kinescope demagnetization of selecting other models for use with the PTC element all can, also available colour TV replaces with two pin thermal sensitivity field-discharge resistances.The model difference of PTC, little to the influence that delay time causes, what influence delay time mainly is the power of incandescent lamp.

When circuit production, relay J should be selected small-sized 220V AC relay for use, and model is JQX-13F.Be to reduce the cost of manufacture of circuit, AC relay can be selected for use has only get final product of one group of normally opened contact, and the impedance that requires to select for use relay coil greatly some for well.

Circuit debugging:

The length of this circuit delay time directly is subjected to the influence of incandescent light bulb H watt level.Generally the power of incandescent lamp bulb is more little, and delay time is just long more, and then delaying time when the power of incandescent lamp bulb is big just shortens.Delay time length data are substantially when adopting the bulb of different capacity: when incandescent light bulb H power is selected 15W for use, delayed time about 150 seconds; When incandescent lamp H power selects 25W, about 100 seconds of delay time; When incandescent lamp H power was selected 40W for use, time-delay was about 50 seconds.

Under the situation that does not change incandescent lamp bulb power, if the tripod PTC thermal sensitivity field-discharge resistance in the circuit directly is replaced by the inner two pin PTC thermal sensitivity field-discharge resistances of not using with the colour kinescope demagnetization of assistant heating resistance, then incandescent lamp bulb illumination delay time can be more longer.
