Abstract
The utility model discloses a fancy lamp controller which is composed of an oscillator 1, a shift register 2, a random signal generator 3, a lamp driver 4, power supply 5, an outer shell, etc. The random signal generator comprises a noise source 7 and an amplifier 8; random signals generated by the noise source 7 are connected to the serial entry terminal of the shift register 2 after the amplifier 8 amplifies the random signals. The output of the oscillator is connected to the clock input terminal of the shift register 2, output signals from the parallel output terminal of the shift register 2 can make a fancy lamp generate periods and brightness time ratio as stochastic glitter or lighting time and color change periods as flow color light, and changing light is vivid to give people surprise.
Description
The utility model relates to a kind of lamp dimmer, particularly a kind of decorative lamp controller.
The existing decorative lamp controller similar to the utility model is made up of oscillator, shift register, lamp driver, power supply and shell.The input end of clock of shift register is received in the output of oscillator, and the parallel output terminal of shift register is received the input of lamp driver.This decorative lamp controller is mainly used in the complicated decor lamp of control, produces the glory that flows.The problem that this decorative lamp controller exists is that light and shade cycle, light and shade time ratio, the versicolor period of change of light gives setting earlier, and rigid mechanical seems.
It all is decorative lamp controller at random that task of the present utility model provides a kind of light light and shade cycle, light and shade time ratio, versicolor period of change.
Task of the present utility model realizes as follows: on the basis of the existing decorative lamp controller of being made up of oscillator, shift register, lamp driver, power supply and shell, increase a random signal generator.Random signal generator is made up of noise source and amplifier, amplifier input terminal is received in the output of noise source, the serial input terminal of shift register is received in the output of amplifier, the input end of clock of shift register is received in the output of oscillator, and the also line output of shift register is received the input of lamp driver.
Noise source can be a resistance, and amplifier is made up of 5 grades of transistor amplifier circuits.Resistance as noise source, the base stage of the 1st grade of transistor amplifier circuit of its output termination, the collector electrode output of preceding 4 grades of transistor amplifier circuits is capacitively coupled to the base stage of next stage amplifying circuit respectively, and the serial input terminal of shift register is received in the output of the 5th grade of transistor amplifier circuit.
Noise source also can be a microphone, and amplifier is an operational amplifier, and two outputs of microphone are received the positive input and the reverse input end of operational amplifier respectively.
Operation principle of the present utility model is as follows: be noise source with resistance, when 5 grades of transistor amplifier circuits are amplifier, the thermal noise that resistance sends is amplified step by step by 5 grades of amplifiers, in amplification process, sneak into transistorized thermal noise, shot noise and flicker noise again, form 0,1 binary random signal at last.This signal is delivered to the serial input terminal of shift register.Because the clock signal that oscillator produces is uncorrelated with above-mentioned noise, so what enter shift register is random number.Do noise source with microphone, when making amplifier with operational amplifier, pick up the sound wave in space by microphone, it is become the signal of telecommunication, signal becomes 0,1 binary random number through the saturated amplification of operational amplifier, because the clock that the sound wave in space and oscillator produce is uncorrelated, so what enter shift register is random number.Above-mentioned random number is displacement step by step in shift register, forms random data stream.Lamp driver is received in arbitrary grade of output of shift register driven the polychromy lamp, the color lamp that is then glistened at random, its cycle and light and shade time ratio all are unfixed.The parallel output terminal of shift register is received each lamp driver in regular turn, and the color lamp that control is arranged in regular turn then obtains change color cycle and colored length than all being at random mobile light.
Advantage of the present utility model is: the light and shade cycle of light, light and shade time ratio, change color cycle and colored length all are at random, seem lively, have avoided the problem of rigid mechanical.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is a schematic diagram of the present utility model
Fig. 2 is first embodiment of the present utility model
Fig. 3 is second embodiment of the present utility model
Fig. 4 is the outside drawing of second embodiment of the present utility model
Decorative lamp controller described in the utility model is made up of oscillator 1, shift register 2, random signal generator 3, lamp driver 4, power supply 5 and shell 6, and random signal generator comprises noise source 7 and amplifier 8 two parts.In Fig. 1, the input end of clock of shift register 2 is received in the output of oscillator 1, the input of amplifier 8 is received in the output of noise source 7, and the serial input terminal of shift register 2 is received in the output of amplifier 8, and the also line output of shift register 2 is received the input of lamp driver.The noise that noise source forms forms the serial input terminal that 0,1 binary random signal is delivered to shift register 2 after amplifier amplifies, because the clock that this random signal and oscillator 1 produce is uncorrelated, so what enter shift register 2 is random number, this random number is shifted step by step forms random data stream.Lamp driver is delivered in the output of shift register, makes decorative lamp produce at random flash of light, if decorative lamp arranges in regular turn, then can obtain change color cycle and colored length than all being at random mobile light.
