Abstract
The utility model relates to a display lamp with sound, which overcomes the shortage of the prior art and is used for non-power-driven vehicle. The utility model comprises a power switch control box, a sound and light double indicating control box, a buzzer, a direction indicator lamp, etc., wherein, the buzzer is driven by a pulse current amplifying circuit to send out alarm sound. The pulse current amplifying circuit and a resonant circuit of a resonator sending out flickering light perform the flickering function simultaneously. Thus a prewarning device which can send out audible and visual flickering light indicating signals is achieved. The utility model has the characteristics of simple circuit structure, easy installation, reliable performance, convenient operation, low cost, easy application, etc.
Description
The utility model belongs to the signal indicating device of a kind of sound and light.
In known technology, Chinese patent CN2114610U discloses a kind of bicycle backsight cornering lamp, it only provides a kind of can see scenery behind the car, and the function of turning with light indication, do not have the audio early warning, can't make pedestrian, vehicle early warning know that it turns to, and says from safety, no all roses, thereby influence its practicality.Therefore, for traffic safety, and providing a kind of signal prior-warning device of indicating with visible light of listening that is assemblied in non power driven vehicle, is very necessary.
The purpose of this utility model: for overcoming above-mentioned weak point, and provide a kind of light pilot lamp with audio, it is assemblied in (as bicycle, tricycle) on the non power driven vehicle, when the start button switch, make the control enclosure of control audio and light indication send musical sound, whistle or alarm song immediately, vehicle, pedestrian around prenoticing will turn right, turn left or keep straight on, all peace approximately, and assist with the light pilot lamp, more can reach dual indicator signal, guarantee everybody traffic safety.If be assemblied in the non power driven vehicle that dangerous area travels, can warn vehicle, pedestrian near with to avoid traffic hazard.The scope of application is extensive.
In order to realize this purpose, invention scheme of the present utility model is: in Figure of description, Fig. 1 provides the structural representation of the light pilot lamp of band audio, and it is by bi-directional power switch (1), LED light emitting diode lamp (left side) (2) and right (3), power switch control enclosure (4), lead (5), power supply (battery) (6), the control enclosure of audio and the dual indication of light (7), buzzer (loudspeaker) (8), part such as blinker (left side) (9) and (right side) (10) and two Transparent lamp shades (left side) (11) and (right side) (12) is formed.When power switch (1) is turned left switching, LED light emitting diode lamp (left side) (2) is shinny, the display power supply conducting, signal reaches power supply (battery) (6) by lead (5), the control enclosure of audio and the dual indication of light (7) function on, then buzzer (loudspeaker) (8) sound the alarm, musical sound or whistle, blinker (left side) (9) sends the indication of flash signal light immediately simultaneously, warning and indication vehicle, pedestrian are desired to travel left.In like manner, when power switch (1) was turned right switching, LED light emitting diode lamp (right side) (3) was shinny, then sound the alarm equally, blinker (right side) (10) sends the indication of flash signal light immediately simultaneously, and warning and indication vehicle, pedestrian are desired to right travel.Fig. 2 provides the principle of work synoptic diagram of light indicator light circuit structure of band audio, the feature of relevant Fig. 2 circuit structure and be embodied in Figure of description and described in illustrating.
The utility model has following advantage compared with prior art:
1, it is equipped with buzzer (loudspeaker) (8) and is equipped with Transparent lamp shade (11), (12) simultaneously on blinker (9), (10), and place (bicycle, tricycle) on the non power driven vehicle, provide a kind of can for vehicle, pedestrian listens and the signal prior-warning device of visible blinking light indication, make vehicle, pedestrian predict it and turn to, and reach the dual-use function of warning and light indication.When it is assemblied on the non power driven vehicle that dangerous area travels, can warn the not close and one way traffic of vehicle, pedestrian, guarantee everybody traffic safety.The scope of application is extensive.
2, its circuit structure succinct (as shown in Figure 2), it adopts a kind of pulse current amplifying circuit (13) to drive buzzer (loudspeaker) (8), and sound the alarm, and produce flashing function with a kind of flicker resonant circuit (15) simultaneously, the use of working in coordination is listened and the signal prior-warning device of visible blinking light indication thereby reach a kind of.Also have usability reliable and convenient, install easily, cost is low and characteristics such as easy to implement.
Below in conjunction with Figure of description, circuit structure feature of the present utility model and concrete enforcement are further described:
Fig. 2 provides the circuit structure principle of work synoptic diagram of the light pilot lamp of band audio, and it mainly comprises a kind of pulse current amplifying circuit (13) and a kind of flicker resonant circuit (15) two parts.Wherein: comprise operational amplifier (14) (Operational Amplifier) and buzzer (loudspeaker) (8) in the pulse current amplifying circuit (13).Comprise oscillator IC(16 in flicker resonant circuit (15)), blinker (9), (10), power switch control enclosure (4), power supply (battery) (6) and lead (5) etc. form.Have circuit structure succinct, install easily and the scope of application extensive.Its work is to adopt a kind of operational amplifier (14) analog computation to amplify light pulse to produce pulse current amplification driving buzzer (loudspeaker) (8), and sound the alarm, and simultaneously and a kind of oscillator IC(16) send flicker resonant circuit (15) and produce flashing function, the use of working in coordination, listen and the signal prior-warning device of visible blinking light indication and reach a kind of, promptly with the light pilot lamp of audio.
Promptly constitute the utility model according to above-mentioned making---the light pilot lamp of band audio.
Claims (2)
1, a kind of light pilot lamp with audio, control enclosure, blinker (9), (10) and Transparent lamp shade (11), (12) composition of comprising bi-directional power switch (1), LED light emitting diode lamp (2), (3), power switch control enclosure (4), light indication, the control enclosure that it is characterized in that the light indication is a kind of control enclosure (7) with audio and the dual indication of light, be equipped with a kind of pulse current amplifying circuit (13) in it and drive hummer (loudspeaker) (8), with a kind of flicker resonant circuit (15), finish the dual indication of audio and wigwag.
