Abstract
The utility model relates to a device which can perform an alarm function when people walk and a bicycle is ridden at night. The utility model is similar to a tail lamp of a bicycle. The utility model more particularly relates to the improvement to the tail lamp of a bicycle. The output end of a narrow pulse generator which is composed of a time base component IC and a resistor capacitor component is connected to a base electrode of a crystal triode V< T >, and an emitting electrode and a collecting electrode of the V< T > are respectively connected with a music transistor V< J > of a buzzer Y and a light emitting diode V< D >. The utility model can evenly perform a peripheral alarm function no matter whether people walk or a bicycle is bicycle; the utility model is practical on roads of suburbs and villages which do not have the illumination of street lamps. The alarm of the utility model is obvious.
Description
The utility model is the device that can play warning function when night, the people walked garage, and it is similar to Bicycle Tail Light, specifically to a kind of improvement of Bicycle Tail Light.
Former Bicycle Tail Light generally all is under the irradiation of external source light, makes the photosensitive material on the taillight luminous, and is the afterbody that is fixed on bicycle, changes direction and position inconvenience, and particularly the vehicle in the front and back dealing does not have under the situation of light, is difficult for being found.In addition, the Bicycle Tail Light that throughout the year travels has 90% to be broken, lost or worn out, and does not have warning function.
The utility model is at above-mentioned deficiency, provides a kind of and is formed and warned tangible multifunctional musical flasher by electronic component, and it is small and exquisite, is easy to carry and hangs.
Technical essential of the present utility model is:
The narrow-pulse generator output terminal pin that is made of time base assembly IC and Resistor-Capacitor Unit is to transistor V
TBase stage, V
TEmitter and collector the music triode V of hummer Y is arranged respectively in succession
JWith light emitting diode V
D
No matter the utility model can be realized is the people is walked the warning function of garage around all can playing, especially on the outskirts of a town, country do not have on the road of street lamp illumination more practical.Its caution obviously, and is small and exquisite, installation, easy to carry.
Description of drawings:
Fig. 1 is an appearance structure synoptic diagram of the present utility model.
Fig. 2 is circuit theory diagrams of the present utility model.
The principle of work of the utility model warning lamp:
The utility model is a kind of electronic music flashlamp, is made up of shell, movement two parts, as depicted in figs. 1 and 2.Circuit structure in the movement is by time base circuit ic chip (NE555) and resistance R as shown in Figure 2
1, R
2With the narrow-pulse generator of capacitor C composition, and the burst pulse of generation dutycycle＜10%, capacitor C is connected between 2 pin and 5 pin of time base circuit ic chip (NE555), output triode V
T4 pin, 8 pin of emitter (CD9015) and IC piece join, and base stage and 3 pin join, collector and high brightness LED V
DPositive pole link to each other, making 3 pin of the moment IC integrated package of energized is low level, light emitting diode V
DOnce glittering immediately.Because R
1, R
2The recurrence interval that the pulse producer of forming with the cooperation of C and IC integrated package produces is about 0.6 second, and pulse width is about 0.5 millisecond, so as long as will make V after the energized
DConstantly step glittering (red light).Also started simultaneously the work of music triode VJ (VT66A06L), sent specific musical sound by hummer Y, just all stop to turn off power supply.
The utility model will be installed No. 5 batteries of two joints in use, opening switch just can work, when sending the red light of coruscating, play out specific music sound, can hang over any position of bicycle flexibly or wear on the waistband of human body, on the cap, on student's the school bag and old man's the first-class position of walking stick.
Among Fig. 11 is flash tube, and 2 are the flash of light groove, and 3 are the flash of light cover, and 4 is switch, and 5 is movement Lid, 6 is bottom, and 7 is strap clamp, and the K among Fig. 2 is power switch.
