Abstract

The utility model relates to an LED bulb lamp applied to a sound/light control switch. A control circuit is additionally arranged before an AC/DC constant current driving power supply of the LED bulb lamp, wherein the control circuit is composed of a fuse, a metal film capacitor (C=0.47muF), a bleeder resistor (R=512K), a rectifier bridge and a relay (DC24V), the metal film capacitor and the rectifier bridge form a resistance-capacitance DC voltage reducing circuit so as to drive the low-voltage DC relay, and the function of the bleeder resistor is to release electric energy stored by a metal film rapidly when there is no operation power supply. The circuit provided by the utility model can enable the sound/light control switch, which is not special for LED lamps, to switch off completely with no current flowing through when the sound/light control switch stays at an off state with small current flowing through.

Description

A kind of LED bulb lamp that is applicable to sonic-opticalcon trolled switch
Technical field
The utility model relates to bulb, relates in particular to a kind of LED bulb lamp that is applicable to sonic-opticalcon trolled switch.
Background technology
Existing sound-light controlled LED bulb lamp has following way, and a kind of is to change common sonic-opticalcon trolled switch internal circuit, makes sonic-opticalcon trolled switch can control the on and off of LED lamp fully.Thereby another kind is the lamp socket the inside realization delay switch function that the sound and light controlled delay switch circuit is installed to the LED bulb lamp.Realize that the scheme that the collocation of sonic-opticalcon trolled switch and LED bulb lamp is used has following several:
1. the sonic-opticalcon trolled switch that more renews changes acousto-optic control internal control part, can disconnect alternating current fully when making its disconnection.
2. install the acoustooptic controlled delay circuit for LED in lamp socket additional, the conventional acoustic light-operated switch before substituting is controlled the LED bulb lamp.
3. do not do circuit modification, directly the LED lamp is used on the conventional acoustic light-operated switch, LED is switched between half bright and complete bright state.
The utility model content
Technical problem to be solved in the utility model provides a kind of LED bulb lamp that is applicable to sonic-opticalcon trolled switch, before the AC/DC of LED bulb lamp constant-current driving power supply, install one additional by reaching fuse, metal film electric capacity, bleeder resistance, rectifier bridge, the control circuit that relay is formed, this circuit can make sonic-opticalcon trolled switch (the special-purpose audio-switch of non-LED lamp) realize disconnecting completely (no current flows through) when being in off state (being that little electric current flows through).
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of LED bulb lamp that is applicable to sonic-opticalcon trolled switch, comprise the AC/DC constant-current driving power supply, metal film electric capacity (C=0.47 μ F), bleeder resistance (R=512K Ω), rectifier bridge, relay (DC24V), described rectifier bridge is by diode D1, diode D2, diode D3, diode D4 forms, the negative pole of described diode D1 links to each other with the negative pole of diode D2 and forms first node, described diode D3 negative pole link to each other with the positive pole of diode D2 and form second node, the positive pole of described diode D4 links to each other with the positive pole of diode D3 and forms the 3rd node, and the negative pole of described diode D4 links to each other with the positive pole of diode D1 and forms the 4th node; Described metal film electric capacity is in parallel with bleeder resistance, a node that forms after described metal film electric capacity and the bleeder resistance parallel connection links to each other with the 4th node of described rectifier bridge, second node of described rectifier bridge links to each other with the negative input mouth of AC/DC constant-current driving power supply, first node of described rectifier bridge is by the coil ground connection of relay, another node that forms after the 3rd node ground connection of described rectifier bridge, described metal film electric capacity and bleeder resistance parallel connection links to each other with the electrode input end mouth of AC/DC constant-current driving power supply by the contact of relay.Be provided with fuse between another node that forms after described metal film electric capacity and the bleeder resistance parallel connection and the contact that relay is connected.Metal film electric capacity and rectifier bridge constitute the resistance-capacitance type direct-current voltage reducing circuit, thus the low direct current relay of driving voltage, the effect of bleeder resistance be when the situation that does not have working power can be very fast the metal film electric energy stored is discharged.
For the corridor sonic-opticalcon trolled switch, when switch was in off-state, it also had less current to flow there through on the lamp holder.Because tungsten lamp or incandescent lamp can not be lighted when less electric current flows through, and the AC/DC constant current driving in less electric current of LED lamp still can be worked, and just the brightness meeting is lower.Therefore a kind of LED bulb lamp that is applicable to sonic-opticalcon trolled switch of the present utility model had added the control device that a resistance-capacitance type reduction voltage circuit and relay are formed before the LED constant current drives.When sonic-opticalcon trolled switch is in off-state, it is less namely to flow through electric current, after the resistance-capacitance type step-down, it is very little to flow through relay current, does not reach its specified electric current, and then relay is in off-state, thereby the live wire in the partition alternating current, thereby reach the effect that the LED lamp is closed fully; The electric current that then flows through control device when sonic-opticalcon trolled switch is in conducting state also becomes greatly, and the coil of its relay will adhesive, and the LED lamp will be lighted fully.
The beneficial effects of the utility model are: under the situation of the sonic-opticalcon trolled switch that does not need to change or lamp socket, can directly the utility model product and sonic-opticalcon trolled switch be used, the control effect that realization is the same with tungsten lamp or incandescent lamp, can reach convenient and purpose of power saving more, the LED bulb lamp that can be used as of the utility model product is used for the work of interior length time illumination simultaneously.
