Abstract

The invention discloses a bicycle headlight comprising a light body, a support, and a clamp. The front end of the light body is provided with a lamp connected with a power source. The support is connected with the light body. The clamp is connected with the support and used for fixing a bicycle frame. The front end of the light body is further provided with an indicator light connected with the power source. The indicator light is arranged above the lamp. The axis of the indicator light is parallel to that of the light body. The axis of the lamp inclines down and forms an included angle of 15-40 degrees with the axis of the light body. The bicycle headlight has the advantages that illumination light can be prevented from directly shining to opposite passengers or vehicle drivers so as to avoid affecting normal walking of the opposite passengers or normal riding of the vehicle drivers, during bicycling; meanwhile, the bicycle headlight is capable of reminding the opposite passengers or vehicle drivers of avoiding.

Description

Bicycle headlight

Technical field

The present invention relates to a kind of lamps and lanterns, is specifically a kind of bicycle headlight.

Background technology

Bicycle headlight is generally arranged in bicycle handle bar, for illumination is provided when bicycle running, bicycle generally comprises lamp main body, support and holder, lamp main body detouchable is fixed on support, support and holder are rotatably connected, holder and bicycle handle bar fix, when bicycle headlight is used, lamp main body is horizontally disposed with, the illuminating lamp that is arranged on lamp body front end is also horizontally disposed with, when after illuminating lamp energising, the optical axis of illuminating lamp is horizontal direction, make when bicycle running, pedestrian or vehicle driver in bicycle opposite direction are easily subject to the direct irradiation of illuminating lamp light and feel that light is comparatively dazzling, this will hinder pedestrian or the vehicle driver's of bicycle opposite direction normal walking or driving, even can cause the generation of traffic accident.

Summary of the invention

Technical matters to be solved by this invention is, provide a kind of and when bicycle running, can avoid pedestrian that illuminating ray shines directly into opposite or vehicle driver to avoid the pedestrian or the vehicle driver's that affect opposite normal walking or driving, and can remind the pedestrian on opposite or vehicle driver to note the bicycle headlight of dodging simultaneously.

For solving the problems of the technologies described above, bicycle headlight provided by the invention, it comprises lamp main body, its front end is provided with the illuminating lamp being connected with power supply; Support, is connected with described lamp main body; Holder, is connected with described support and for fixing with cycle frame; The front end of described lamp main body is also provided with the indicator lamp being connected with power supply, and described indicator lamp is located at the top of illuminating lamp, and the axis of described indicator lamp parallels with the axis of lamp main body; The axis of described illuminating lamp is downward-sloping, and becomes 15 ~ 40 degree angles with the axis of lamp main body.

Adopt after above structure, the present invention compared with prior art, has advantages of following:

After lamp main body level is arranged in bicycle handle bar, the axis of lamp main body is horizontal direction, because the axis of illuminating lamp is downward-sloping, make when illuminating lamp is luminous, the optical axis of illuminating lamp is downward-sloping, make the pedestrian of bicycle opposite direction or vehicle driver can not be subject to the direct irradiation of illuminating lamp light, just can not make bicycle opposite direction pedestrian or vehicle driver feel that light is comparatively dazzling yet, the light of illuminating lamp can provide illumination for travelling of bicycle, simultaneously owing to being also provided with indicator lamp, the axis of indicator lamp is horizontal direction, the optical axis that makes indicator lamp is horizontal direction, when indicator lamp glimmers, the pedestrian of bicycle opposite direction or vehicle driver can be than the light that is easier to see indicator lamp, thereby dodge in time bicycle.

As preferably, the axis of described illuminating lamp becomes 20 degree angles with the axis of lamp main body.Now, it is far away that the light of illuminating lamp can irradiate, in the time of can making bicycle running, bicycle driver can be seen longer-distance road surface, bicycle front clearly, and now the light of illuminating lamp also can not shine directly into pedestrian or the vehicle driver on bicycle opposite, now the lighting effect of illuminating lamp is best.

As preferably, the rear end of described lamp main body is also provided with the taillight being connected with power supply, and the axis of described taillight is inclined upwardly, and becomes 20 ~ 50 degree angles with the axis of lamp main body, and the axis of described taillight becomes 40 degree angles with the axis of lamp main body.Like this, when bicycle driver is worn reflective vest with it, the light of taillight can be irradiated on reflective vest, reflective vest can comparatively easily be seen by the pedestrian of bicycle opposite direction or vehicle driver, to play warning function, and the axis of taillight is inclined upwardly, the light of taillight can be irradiated on the reflective vest at position, bicycle driver chest, make pedestrian or the vehicle driver of bicycle opposite direction more easily see reflective vest, and when giving bicycle headlight charging of the present invention, taillight can be used as charge condition indicator lamp.

As preferably, in described lamp main body, be also provided with USB interface, switch, charge circuit, battery pack, booster circuit and controller, the mouth of USB interface is electrically connected with the input end of battery pack by charge circuit, the mouth of battery pack electrically connects as controller power supply by the input end of booster circuit and controller, the mouth of battery pack is electrically connected the voltage that makes controller detect battery pack with the input end of controller, the mouth of controller is electrically connected with the on-off element in charge circuit the break-make that makes controller control charge circuit, switch is electrically connected with the signal input part of controller, three power output ends of controller respectively with illuminating lamp, indicator lamp and taillight electrical connection.Like this, controller can judge that battery pack is rechargeable battery or general dry battery by the voltage that detects battery pack, when USB interface is pegged graft after upper charging wire, if it is rechargeable battery that controller detects battery pack, controller control charge circuit conducting, now by USB interface, can give batteries charging, if it is general dry battery that controller detects battery pack, controller control charge circuit disconnects, now the electric current of USB interface cannot be transported to battery pack by charge circuit, that is to say that battery pack in the present invention can be used rechargeable battery or general dry battery power supply, and controller can control accordingly the break-make of charge circuit so that proper battery pack can be its charging by USB interface while being rechargeable battery, it when battery pack is general dry battery, is not its charging, to avoid to general dry battery charging and to have an accident.
