Abstract
The present invention provides a photoelectric control circuit unit and a music revalving lamp using said circuit unit. It utilizes pulsating electric signal produced by photoresistor measuring head of the control circuit which is irradiated by flickering light beam passing through several ligth holes circularly distributed no the turnable drum to control conduction of triode so as to control playback of music crystal wafer. When the lamp is put out or the drum is not turned, the photoresistor of control circuit does not produce pulsating electric signal, triode is cut off and the music crystal wafer does not produce sound. When the light is darkened or the rotation of the drum is slowed, the music playback speed also is slowed.

Fig. 5 shows the circuit theory diagrams of the first embodiment of the present invention;
Fig. 6 shows the circuit theory diagrams of second embodiment of the invention;
Hereinafter will describe the present invention in detail.
As shown in Figure 1, rotating cylinder 2 when opening bulb 3, because the rising hot-air of its generation promotes the blade 22 on the rotating cylinder 2, thereby is realized the effect of common revolving horse lantern on support 41.Rotating cylinder 2 peripheries of music revolving horse lantern of the present invention have a plurality of loopholes 21, when this rotating cylinder 2 rotates, and the photo resistance gauge head 5 that the light beam that this loophole 21 appears is inswept between rotating cylinder 2 and lampshade 1, as shown in Figure 4, thus the generation pulse electrical signal.
As shown in Figure 4, circuit box 6 is positioned at the central authorities of revolving horse lantern bottom bracket 4, and there is a music switch 65 its side, and this switch is used for cutting out fully the music sounding.The circuit of circuit box 6 connects and scheme of installation, and as shown in Figure 2, sound-producing device 66 is positioned at a jiao of circuit box 6, and it is to there being the penetrable sound hole 662 and 661 on lid 63 and lid 64, and wherein penetrable sound hole 661 is illustrated among Fig. 1.Music wafer 61 is positioned at that other element is positioned on another circuit board 62 on the circuit board 60.Switch body 652 usefulness one nut 651 of music switch 65 is fixed in the side of box body 64.Revolving horse lantern profile after installing as shown in Figure 3.
The circuit theory of the light-operated music generation of music revolving horse lantern of the present invention is described in conjunction with first and second embodiment respectively below.
First embodiment: above-mentioned photo resistance gauge head 5 correspondences are exactly the photoresistance cell GR1 among Fig. 5 and Fig. 6, the pulsatile change signal of telecommunication that this photo resistance produces when described rotating cylinder 2 rotates is through partiting dc capacitor C1 and coupling resistance R3 elimination direct current and after being coupled, via detector diode D2 detection, and after the filter capacitor C2 filtering, the input of the flat input comparator U1A of output DC.When bright and rotating cylinder 2 rotated when bulb 3, the anti-phase output low level of this comparator was controlled the conducting of transistor Q1, thereby, be connected on music wafer U2 in this emitter loop with regard to sounding.
If bulb 3 does not work, or rotating cylinder 2 does not change, photo resistance GR1 goes up the signal of telecommunication that does not just have variation, therefore can only export the dc signal of varying strength at most, because dc signal can not pass through partiting dc capacitor C1, therefore pass through the circuit no signal of filtered diode D2, thereby do not have control signal through the base stage that comparator U1A exports to transistor Q1 after relatively, thereby its emitter circuit can not conducting, and music wafer U2 just can't sounding.
When bulb brightness descended, the level of photo resistance GR1 output descended; When the rotating cylinder rotating speed descended, the signal frequency of photo resistance GR1 output descended.Below either way will cause the base stage control level of the first transistor Q1 to descend, thereby this first transistor emitter circuit electric current is diminished, the sounding of music wafer U2 is also just correspondingly slack-off, so just can judge whether revolving horse lantern is normal by musical sound.
In actual use, also can simply this first transistor Q1 be connected into the electronic switch of a tool on-off function, it be had only connect and block two states.Like this, musical sound just has only sounding and sounding two states not, can't reflect that the brightness of light and the speed of rotating cylinder rotating speed have changed.
Second embodiment: as shown in Figure 6, be the circuit theory diagrams of further embodiment of this invention.Be with the difference of first embodiment: employed dc source is provided by a rectification circuit; Between photo resistance GR1 and partiting dc capacitor C1, increased pre-driver stage integrated circuit U3B, the signal of input has been amplified once earlier; After this partiting dc capacitor C1, increased an integration amplifying stage integrated circuit U3A, signal has been amplified again.What present embodiment was considered is in the room of lamp more than, the situation that surround lighting is very bright, photo resistance GR1 is not only shone by bulb 3, also can be thrown light on by surround lighting, and the part that increases just guaranteed can both operate as normal under various surround lightings.
The effect that should be pointed out that switch J in the foregoing description simultaneously is to open or close overall optical control circuit unit, can directly not turn off the music sounding when needing music to be implemented in.
Should be understood that the one of ordinary skilled in the art can make various suitable changes, and these changes all should belong to protection scope of the present invention without departing from the inventive concept of the premise.
