Description

The bicycle signal lamp

The utility model belongs to the configuration of optical signalling on the bicycle, installs and used circuit.

Existing bicycle signal lamp, as CN1116172A, indicator for bicycle and CN2043589U, turning of bicycle lamp adopt bulb as luminous element, to show the motoring condition of bicycle.The power consumption of these two kinds of devices is big, and is impracticable.CN2043590U and for example, bicycle flash of light taillight, its adopts light-emitting diode as luminous element, though little power consumption, its brightness is low, irradiation distance is little.

The purpose of this utility model is that design is a kind of luminous strong, irradiation distance far, the bicycle signal lamp of power saving again.

Below, narrate structure of the present utility model.

The utility model comprises box body, is equipped with in box body by semiconductor light emitting piece D ₁D ₂Rear and K switch in parallel ₁Be composed in series the signal lamp loop that bicycle normally travels with power supply Ec.By triode T ₁T ₂Emitter stage and the positive pole of power supply Ec link, base stage is passed through resistance R ₁R ₂Link with the negative pole of power supply Ec, colelctor electrode meets semiconductor light emitting piece D ₄D ₆And D ₃D ₅, and K switch ₂K ₃Negative pole rear and power supply Ec links, at triode T ₁Base stage and T ₂Colelctor electrode between flying capcitor C ₁, at triode T ₂Base stage and T ₁Colelctor electrode between flying capcitor C ₂Form turning flashlight loop about bicycle.Front at each semiconductor light emitting piece is equipped with eye gauge.

K switch ₁Main supply switch for entire circuit.

For the ease of night running, a small bulb L can be installed, it and K switch in the front portion of bicycle ₄Ec is composed in series lighting loop with power supply.

Above-mentioned eye gauge can be convex lens, also can be polygon prism.Through evidence eye gauge shape as shown in Figure 2, its best results.It is shaped as the middle part is four-prism AC ₁, both sides be two symmetries with four-prism AC ₁Positive rectangular pyramid S-AC and S with the bottom surface ₁-A ₁C ₁

As close switch K ₁The time, be positioned at two semiconductor light emitting piece D before and after the bicycle ₁D ₂Luminous, the indication bicycle normally travels.When about wanting, turning, can close switch K ₂Or K ₃, make by resistance R ₁R ₂, capacitor C ₁, C ₂, triode T ₁T ₂, semiconductor light emitting piece D ₃D ₄Or D ₅D ₆Multivibrator work with power supply Ec composition.Multi-vibrator is a representative type primary electron circuit.Two temporary transient stabilized conditionss are arranged under the normal circumstances.Perhaps aerotron T ₁Conducting, D ₄Or D ₆Bright, T ₂End; Perhaps aerotron T ₂Conducting, D ₃Or D ₅Bright, T ₁End.By resistance R ₁R ₂Give triode T ₁T ₂Base current is provided, for guaranteeing the better conducting of triode, should makes R _b＜β Rc.Triode T ₁T ₂Alternate conduction, semiconductor light emitting piece D ₃D ₅Or D ₄D ₆Jaundice look flashing signal.

Because the utility model adopts the semiconductor light emitting piece as light-emitting component, and settles magnifying glass in its front, so just obtained luminous by force, irradiation distance is far away, again the effect of power saving.

Embodiment;

This bicycle signal lamp is by semiconductor light emitting piece D ₁D ₂Rear and K switch in parallel ₁Be composed in series the signal lamp loop that bicycle normally travels with power supply Ec.Semiconductor light emitting piece D ₁D ₂Place respectively before the car and the tail-light place, the normal bright red eye of front and back indication when consisting of night running for bicycle.Direction signal lamp loop, the left and right sides is as follows; Aerotron T ₁T ₂Emitter and the positive pole of power supply Ec link, base stage is passed through resistance R respectively ₁, R ₂Link three plate pipe T with the negative pole of power supply Ec ₁Collecting electrode meet semiconductor light emitting piece D ₄And K switch ₂, perhaps meet semiconductor light emitting piece D ₆And K switch ₃The back links aerotron T with the negative pole of power supply Ec ₂Collecting electrode meet semiconductor light emitting piece D ₃And K switch ₂, perhaps meet semiconductor light emitting piece D ₅And K switch ₃Link with the negative pole of power supply Ec.At triode T ₁Base stage and T ₂Colelctor electrode between flying capcitor C ₁, at triode T ₂Base stage and T ₁Colelctor electrode between flying capcitor C ₂Four semiconductor light emitting piece D ₄, D ₆, D ₃, D ₅Place bicycle handle bar two ends and taillight both sides respectively.Be equipped with small spotlight L at bicycle front fork, it passes through K switch ₄Form lighting loop with power supply Ec.The illumination zone of small spotlight L can reach five sq ms.Be mounted with eye gauge shown in Figure 2 in each front of partly leading this light-emitting block, the semiconductor light emitting piece places the rectangular pyramid summit S and the S of eye gauge ₁Near.In order to cooperate the signal lamp indication to turn, in positive plate and the K switch of power supply Ec ₂, K ₃Between connect language ic chip and loud speaker Y so that sound simultaneously, reminds people is taken care.

Present embodiment adopts germanium triode, and its knot pressure drop is little, and load capacity is strong.The power consumption of semiconductor light emitting piece is little, and No. 5 batteries of two joints are used two months at least, and two No. 2 battery can be used half a year.In addition, owing to place eye gauge before the semiconductor light emitting piece, light is strengthened, visual range reaches 50 meters.
