specific Embodiment 1

[0016] Specific embodiment one: the AC control unit includes a fuse FU, a first diode D1, a second diode D2, a single-pole double-throw switch SA1, one end of the fuse FU is connected to the fire wire, the other end of the fuse FU, and the first diode D1 The anodes are respectively connected to the cathode of the second diode D2, the two selection ports of the SPDT switch SA1 are respectively connected to the cathode of the first diode D1 and the anode of the second diode D2, and the fixed end of the SPDT switch SA1 is connected to the lighting Light connection; the normally open contact KJ of the relay is connected in series between the lighting fixture and the neutral line; the DC control unit includes: a triode VT, a base resistor Rb, a DC switch SA2, one end of the base resistor Rb is connected to the base power supply Ub, and the base The other end of the resistor Rb is connected to the base of the triode VT through the DC switch SA2, the emitter of the triode VT is...

specific Embodiment 2

[0017] Embodiment 2: On the basis of the lighting lamp controlled by multiple switches described in Embodiment 1, it also includes a rectifier for converting the AC voltage between the live wire and the neutral wire into a base voltage Ub and an operating voltage Ue.

[0018] The working principle of the illuminating lamp controlled by the multi-stay switch of the present invention is as follows: the fuse FU disconnects the connection between the illuminating lamp and the live wire when the line fails; When connecting, when the DC switch SA2 acts, the triode VT conducts, and the working power supply Ue charges the relay resistance R. After the relay resistance R is powered, the relay normally open contact KJ absorbs and lights up; if at this time, the single pole double throw The switch SA1 is connected to the second diode D2, and because the diode D2 is turned off, the lighting lamp is turned off.

[0019] It can be seen that the lighting lamp controlled by a multi-way swit...

Abstract

The invention discloses a lighting lamp controlled by multi-way switches, and belongs to the technical field of lighting lamps. The lighting lamp controlled by the multi-way switches comprises an alternating current control unit, a direct current control unit and a relay, wherein the alternating current control unit is connected with the direct current control unit through the relay. The alternating current control unit comprises a fuse, a first diode, a second diode and a single-pole double-throw switch. The direct current control unit comprises a triode, a base resistor and a direct current switch. According to the lighting lamp, the circuit is simple, and the lighting lamp can be controlled in a multi-way mode on the alternating current side and the direct current side.

Description

technical field [0001] The invention discloses a constant temperature and humidity system, in particular to a constant temperature system which utilizes waste heat controlled by constant temperature for constant humidity control. Background technique [0002] The use of lights is no longer satisfied with simple switch control. The multi-way switch controls the lighting lamp so that the application range of the lighting lamp is wider. The existing multi-way switch control is mostly the control of multiple switches on the AC side or the control of multiple switches on the DC side, and the control of multiple switches on the AC side and DC side is rare. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an illuminating lamp controlled by a multi-way switch in view of the deficiency of the above-mentioned background technology. [0004] The present invention adopts following technical scheme for realizing above-mentio...
