Description

A kind of lighting system that changes with music

The utility model belongs to the ornament lamp photosystem

The known lighting system that changes with music is made up of lamp, audio signal source, control circuit, the input termination audio signal source of control circuit, output termination lamp.Control circuit is handled the back output fluctuating signal with music intensity and frequency change to audio signal, and the control lamp is bright, go out.15 pages of the 1st phases of " radio " magazine 1986 provide a kind of " colour music controller ", and by the signal that audio signal source is drawn, as the silicon controlled trigger voltage, lamp is bright when this voltage is higher than the silicon controlled conducting voltage after transformer boosts, otherwise lamp goes out.The shortcoming of this lighting system is that a lamp only glimmers a fixed position, does not have sense of movement, and the light variation pattern is single, and effect is relatively poor.Utilize the signal behind the frequency division to remove to control many color lamps,, make the complicated cost of circuit increase like this, and lighting effects are still not ideal enough though can strengthen lighting effects.108 pages of " practical electronics digest " 4 phases in 1993 provide a kind of " disco race lamp ", scheme is, audio signal is added to ten inputs of being made up of two 4017 integrated circuits that select a control circuit after amplifying, the pulse signal control of control circuit output is connected on amplitude and the frequency order conducting of 10 light emitting diodes of its output along with audio signal, the lighting effects that generation is run with music, this lighting system still is that a lamp only glimmers in a fixed position, want a plurality of lamps could produce the flow effect that changes with music, and this disco race lamp controller can only drive low power lamp.

The purpose of this utility model provides the better lighting system of many lamps lighting effects bright with music signal amplitude and frequency, that go out that an a kind of lamp can be created in diverse location.

The purpose of this utility model is achieved in that to tighten at a motor-driven axle installs a support, and when motor rotated, this drive support rotated, and at least one lamp is contained in support has certain distance apart from the centre of gyration position.A lighting control circuit that is connected to audio signal source at input is realized electrically connecting by brush and the conducting ring and the lamp on the support that are contained on the turning cylinder, this light is controlled electric network can export the fluctuating signal that frequency and amplitude with audio signal change, and the control lamp is bright, go out.Control circuit can be the known lighting control circuit that changes with music.The lamp that is contained on the support slowly runs around axle under driven by motor, the different position differences of lamp constantly, lower and when identical when the number of times of lamp per second light on and off with the support revolutions per second, that lamp seems to seem is bright position, go out, when lamp per second light on and off number of times is higher than the support revolutions per second, lamps that lamp seems as if several are in diverse location bright, go out, like this, when fluctuating signal that one of control circuit output changes with music, lamp is just bright with music rhythm, go out.A lamp with the support motion just can produce the effect of a plurality of lamps in the diverse location flicker, be rich in sense of movement and multiple variation, strengthened lighting effects, on a support, adorn the lamp of a plurality of different colours, or, can make lighting effects better in the such system of several covers of certain room device.

Fig. 1 is the swinging mounting structure chart that lamp is housed.

Fig. 2 is contained in the another kind of mode that the lamp on the support is electrically connected with the realization of control chart circuit.

Fig. 3 is an embodiment of the present utility model.

Fig. 4 is second embodiment of the present utility model.

Fig. 5 is the 3rd embodiment of the present utility model.

The utility model is described in further detail below in conjunction with drawings and Examples:

Be 1 to be lamp among Fig. 1, the 2nd, support, 3,3 ' and 4,4 ' is lead, 5,5 ' is brush, the 6th, motor, 7,7 ' is conducting ring, the 8th, motor shaft.Support 2 fastening being installed on the motor shaft 8, lamp 1 is installed on the support 2, and two leads 3,3 ' are electrically connected with two conducting rings 7,7 ' respectively, insulate between two conducting rings.Two leads 4,4 ' are electrically connected with two brushes 5,5 ' respectively, and brush and conducting ring are close to connect airtight to touch and realize being electrically connected.Lead 4,4 ' two end A, B are electrically connected with the control circuit output.

Among Fig. 2, lead 4,4 ' respectively with two bearings, 10,11 outer ring is electrically connected, and is contained in the supply lines 3,3 ' of the lamp 1 on the support 2 one and is electrically connected with axle 8, another root is electrically connected with the inner ring of bearing 10, bearing 10 and spools 8 carry out electric insulation by lining 9.

When motor 6 rotated, the lamp that is contained on the support 2 just rotated around its centre of gyration.

Among Fig. 3, the 12nd, audio signal source, the 13rd, control circuit, the signal of being drawn by audio signal source 12 as the trigger voltage of controllable silicon SCR, removes to control lamp 1 after transformer B boosts, when the voltage of audio signal is higher than the silicon controlled trigger voltage, the controllable silicon conducting, lamp is bright, on the contrary controllable silicon ends, lamp goes out, and the lamp that is contained on the support is glimmered with music.Because lamp 1 is with the support rotation, and lamp is bright, going out changes with music, therefore a lamp just can produce the effect that many lamps change with music.

Fig. 4 sound intermediate frequency signal is drawn by MIC, is added to deliver to the counter input that is connected into by CD4017 after transistor T 1 amplifies, and pulse signal that changes with audio signal frequency of this counter output is given light emitting diode, makes that it is bright with music, goes out.This light emitting diode is contained in by on the motor-driven swinging mounting.

Control circuit is made of audio signal source 12, preamplifier state 14, voltage controlled oscillator 15 and driving amplifying stage 16 among Fig. 5, a TL081 operational amplifier is connected into an inverting type voltage amplifier, its input termination audio signal source 12, its output is as the input of voltage controlled oscillator 15.7,6,2 pin at a NE7555 integrated circuit are provided with a resistance-capacitance network of being made up of R5, R6, C2 on one side, audio signal after its 5 pin add amplification, make it to become the oscillator of an output signal frequency with the applied signal voltage changes in amplitude, the fluctuating signal that its 3 pin output frequencies change with audio frequency signal amplitude, after the driving amplifying stage 16 that this signal is made of VOMOS pipe T1 amplifies, drive the lamp that is contained on the swinging mounting 1 bright, go out.Adopt to drive amplifying stage and be for can the bigger lamp of driving power,, make its positive pole connect 5 pin of NE7555, can improve the dynamic characteristic of oscillator at high-frequency diode of input string of voltage controlled oscillator 15.

Voltage controlled oscillator 15 in the present embodiment also can be made of other element, for example is connected into a voltage-controlled oscillator with one 3524 integrated circuit.Preamplifier state 14 also can be the identical amplifier of other function with driving amplifying stage 16.The output of voltage controlled oscillator also can directly drive small light such as light emitting diode without amplifying, and also can be used as the silicon controlled triggering signal and removes to control the bigger lamp of power.
