Description

A kind of long life lighting lamp controller

Technical field

This utility model relates to a kind of illuminating lamp, specifically a kind of long life lighting lamp controller.

Background technology

Along with the negative effect caused by Global Greenhouse Effect constantly manifests, every country is all made energy-saving and emission-reduction in the world By the major issue that be must take in native economic development, LED lighting engineering is arisen at the historic moment just under this background An emerging power-saving technology.LED illuminating product has had been applied in daily life, along with developing rapidly of LED at present. The conventional light source that now white LED light source is compared has life-span length, solid state lighting is hardly damaged, specular removal, without hydrargyrum environmental protection, antidetonation Etc. advantage, following will become third generation light source, another revolution of lighting field will be brought, LED in use, too low voltage Being easy to burn device, existing protection circuit the most directly disconnects LED, can cause unexpected dark, Ke Nengyin to user Send out trample, the situation such as traumatic injury.

Utility model content

The purpose of this utility model is to provide a kind of long life lighting lamp controller, to solve in above-mentioned background technology The problem proposed.

For achieving the above object, the following technical scheme of this utility model offer:

A kind of long life lighting lamp controller, including diode D2, chip IC 1, audion V2 and loudspeaker B, described two The anode of pole pipe D2 connects resistance R2, resistance R3, the contact K-1 of relay K, the colelctor electrode of audion V2, the collection of audion V2 Electrode and power supply VCC, the emitter stage relay K of audion V2, the other end of relay K connects the anode of diode D1, current potential One of device RP1 fixes the base stage of the other end connecting triode V1 of end, emergency light L and light fixture H, resistance R2, and resistance R3's is another One end connects negative electrode and the pin 3 of chip IC 1 of diode D1, and the sliding end of potentiometer RP1 connects the pin 1 of chip IC 1, electricity Another fixing end of position device RP1 connects the negative electrode of diode D2, and the other end of the contact K-1 of relay K connects resistance R4, electricity The other end of resistance R4 connects the other end of the emitter stage connection light fixture H of emergency light L, audion V1, and the model of described chip IC 1 is LM321。

As preferred version of the present utility model: described diode D1 is Zener diode.

Compared with prior art, the beneficial effects of the utility model are: this utility model long life lighting lamp controller Simple in construction, components and parts are few, by voltage comparator and audion, relay composition voltage Automatic Protection Switching, run into under-voltage Automatically protect LED during situation, low pressure emergency light can also be automatically turned on simultaneously, reduce the impact caused of turning off the light suddenly, therefore have Service life length, stable performance and the advantage of diverse in function.

Accompanying drawing explanation

Fig. 1 is the circuit diagram of long life lighting lamp controller.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise The every other embodiment obtained, broadly falls into the scope of this utility model protection.

Referring to Fig. 1, a kind of long life lighting lamp controller, including diode D2, chip IC 1, audion V2 and loudspeaker The anode of B, described diode D2 connect resistance R2, resistance R3, the contact K-1 of relay K, the colelctor electrode of audion V2, three The colelctor electrode of pole pipe V2 and power supply VCC, the emitter stage relay K of audion V2, the other end of relay K connects diode D1's Anode, one of potentiometer RP1 fixing end, the base stage of other end connecting triode V1 of emergency light L and light fixture H, resistance R2, electricity The other end of resistance R3 connects negative electrode and the pin 3 of chip IC 1 of diode D1, and the sliding end of potentiometer RP1 connects chip IC 1 Pin 1, another fixing end of potentiometer RP1 connects the negative electrode of diode D2, and the other end of the contact K-1 of relay K connects The other end of resistance R4, resistance R4 connects the other end of the emitter stage connection light fixture H of emergency light L, audion V1, described chip The model of IC1 is LM321.

Diode D1 is Zener diode.

Operation principle of the present utility model is: the core parts of circuit are voltage comparator ics 1, its forward voltage input 3 feet are stable at a constant reference voltage by Zener diode D1, and its backward voltage input 1 foot passes through potentiometer RP1 Obtaining reference voltage, when voltage VCC is normal, its 1 foot voltage is higher than 3 foot voltages, and therefore its outfan 4 foot is low level, three poles Pipe V2 end, now the base stage of V1 all electric, therefore V1 conducting, light fixture H normal luminous, run into VCC voltage be less than under-voltage critical During value, the voltage after diode D2 and potentiometer RP1 dividing potential drop reduces, and therefore 1 foot voltage of chip IC 1 is less than 3 foot voltages, Chip IC 1 exports high level, and V2 turns on, and the base voltage of V1 reduces, now V1 cut-off, disconnects the electric loop of light fixture H, protection It is from under-voltage damage, the contact K-1 adhesive of relay K simultaneously, connects low pressure emergency light L, it is ensured that people will not be in suddenly Situations such as trampling, panic is caused under dark state.

It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and And in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this practicality in other specific forms new Type.Therefore, no matter from the point of view of which point, all should regard embodiment as exemplary, and be nonrestrictive, this practicality is new The scope of type is limited by claims rather than described above, it is intended that by the containing of equivalency in claim that fall All changes in justice and scope are included in this utility model.Should not be considered as any reference in claim limiting Involved claim.

Although moreover, it will be appreciated that this specification is been described by according to embodiment, but the most each embodiment only wraps Containing an independent technical scheme, this narrating mode of description is only that for clarity sake those skilled in the art should Description can also be formed those skilled in the art through appropriately combined as an entirety, the technical scheme in each embodiment May be appreciated other embodiments.
