CN2322868Y - Warning and lighting device using in night running for bicycle - Google Patents

Abstract

The utility model provides a warning and lighting device used in night running for a bicycle. The utility model is characterized in that the device is composed of a power supply, a frequent flashing circuit and a luminous body. Adopting a light emitting diode to conduct the conversion of electricity and light improves the efficiency of the conversion of the electricity and the light. The luminous brightness is increased and the replacement of the warning and lighting device for the night running of the bicycle is solved. The utility model guarantees the safety of the people riding the bicycle at night with long service life, low energy consumption and convenient use.

Description

Bicycle night running alarming and lighting device

The utility model relates to the preceding caution that a kind of night, bicycle running was used, illumination equipment and back alarm signal device.

Develop rapidly along with national economy, improving constantly of people's lives, the increase of vehicle at night and pedestrian's activity remains under the situation that bicycle rides instead of walk in the living standard present as the most Chinese people, how guaranteeing cyclist's safety, is the problem that most of common people are concerned about.The utility model provides a kind of brightness height, energy consumption little, safe and reliable, and the front and back lamp device of the convenient bicycle night running that uses plays the caution and the two kinds of functions of throwing light on.

Luminary (1) shell (7) that stroboscopic circuit (5) that the utility model is connected with power supply by switch (4) by battery (2) and stroboscopic circuit bonded assembly light-emitting diode (LED) constitute and formed by screw (3) the bonded assembly clip (6) that is fixed on the base plate.

Above-mentioned power supply can adopt dry cell power supply.Above-mentioned stroboscopic circuit can adopt integrated circuit such as discrete electronic component or LM3909 to form, and its oscillation frequency is adjustable, as being set at glittering 2000 times of the once glittering or per second of per second.Band switch has three kinds of states: state 1 is outage off attitude, and state 2 be a LED stroboscopic attitude, and state 3 is normal bright attitude (circuit working is under several KHz during this state, and human eye perceives is less than glimmering).

In fact the utility model has two, and its structure is basic identical, and three super bright orange LED of first installation mainly use its normal bright attitude of state 3, as the preposition lamp of bicycle, and caution and illumination.Can also work in stroboscopic state 2.Second installation be two super bright red LED, be in the stroboscopic state, do caution as the bicycle rear taillight and use, a common incandescent spotlight bulb is put in the centre, switch is in 3 attitudes and can be used as illumination and use.

The utility model has changed the traditional approach of using as the bicycle alarm signal, adopt the stroboscopic circuit to change the mechanism by the advanced electric light of super bright lumination of light emitting diode, improved the visual range of signal greatly, reduced energy consumption, ancient dynamo lighting set is eliminated, dynamo-powered lamp is universal not enough, and the utility model provides a kind of light, and cyclist's safety is guaranteed.

Fig. 1 is a structural representation of the present utility model.(what provide is the structure of front car light, and back Vehicle lamp structure is basic identical, and just three orange LED of fwd pipe is changed to two red LED pipes and a Spot light bulb, and is respectively having any different aspect circuit connection and the adjustment.)

Fig. 2 is a circuit block diagram

Luminary of the present utility model is made up of several super bright light-emitting diodes (1) that are embedded on the poly (methyl methacrylate) plate, and battery (2) provides LED stroboscopic circuit power (5) by switch (4).Band switch has three-state, and outage, stroboscopic and normal bright three mode of operations are provided.

The utility model provides a clip can be clipped in easily on front truck handle and the back clothes hanger, and can arbitrarily adjust light direction, uses very convenient.The utility model is done on being applied to bicycle the using of caution and illumination, also can be used as the usefulness of other traffic in the caution and the illumination at night.

Claims (3)

1, bicycle night running alarming and lighting device is characterized in that: in this caution, illumination equipment, and the luminary that connects the stroboscopic circuit and form by light-emitting diode by power supply with the circuit bonded assembly.

2, bicycle night running alarming and lighting device as claimed in claim 1, it is characterized in that: described stroboscopic circuit can be made up of integrated circuit such as discrete component or LM3909, and its circuit can work in Chang Liang and stroboscopic two states, and its circuit assembly adopts epoxy encapsulation technology.

3, bicycle night running alarming and lighting device as claimed in claim 1 is characterized in that: its luminous element is a light-emitting diode, and several light-emitting diodes are embedded in forms luminary in the organism glass.
