Description
Technical field
The present invention relates to a kind of bicycle lamp device, particularly relating to one does not need portable lamp source, reflector or lens, namely has the bicycle lamp device of far and near lamp function.
Background technology
Vehicle clamp mounting product guarantees the safety driving bicycle on bicycle, it is one of common active means of defence, mainly avoid that context is dim, insufficient light, to throw light on travel route warn other people and note increasing the security driving bicycle through car light.Especially the bicycle headlight in bicycle front is arranged on, bicycle headlight is dependent on entirely in the main illumination source of whole travel route, Regular Bicycle lamp only provides illumination with single light source mostly, can only illuminating bicycle anterior position nearby, still has not enough disappearance in actual use.
And develop many dynamo lighting sets with adjustment distance-light illumination zone on the market, and adjust illumination zone and mainly contain portable lamp source, the mode such as reflector or lampshade, by the relative distance adjusting lamp source and reflector, or relative distance between lampshade and lamp source two, change the incidence angle that lamp source enters reflector or lampshade, angle of reflection relatively after reflector or lampshade also changes thereupon, far away to reach adjustment, the illumination zone of low beam, no matter be use portable lamp source, the mode such as reflector or lampshade, all there is complex structure, long-term repetitiousness moves down and has the Sliding Structures abrasion problem such as quick, more can derive mobile its location rear uncertain, and easily driving in process because of road conditions out-of-flatness, structure is caused to produce slippage, cannot correctly provide suitable illumination zone.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of bicycle lamp device with far and near lamp function is provided, through its mode such as structural design and each arrangement of components, the illumination zone of high-low beam light can be controlled, do not need to change lamp source and reflector or the relative position between lamp source and lampshade, the function of far and near lamp illumination can be realized.
The technical solution adopted for the present invention to solve the technical problems is:
There is a bicycle lamp device for far and near lamp function, it is characterized in that: comprising:
One main body, this main body is formed with an accommodating cavity, and this accommodating cavity has a first surface and a second surface;
One lens, these lens are installed in described main body accommodating cavity;
Beat lamp source once, this is lower beats the first surface that lamp source is installed on described main body accommodating cavity, and its some light is oblique to be passed this accommodating cavity and forms a low beam illumination zone;
Beat lamp source, this directly beats the second surface that lamp source is installed on described main body accommodating cavity always, and its some light passes this lens forming one far lamp illumination zone.
Further, described second surface is towards described accommodating cavity light injection direction; Described lens are positioned at describedly directly beats front, lamp source.
Further, described first surface and second surface are that angle is disposed adjacent.
Further, described first surface and second surface are that 90 degree or 270 degree of angles are disposed adjacent.
Further, described lens are the one in single convex lens, biconvex lens or Fresnel Lenses.
Further, described lens are total-reflection type lens, and are provided with one in this main body accommodating cavity and make this lower some light beating lamp source form low beam illumination zone through this reflective surface with lower reflecting surface corresponding to lamp source of beating.
Further, described total-reflection type lens are provided with a burnishing surface, and in described accommodating cavity, correspondence is provided with the 3rd surface, and this burnishing surface is connected to the 3rd surface.
Further, described first surface and second surface are that 270 degree of angles are disposed adjacent, and this second surface is disposed adjacent in 90 degree of angles with the 3rd surface.
It is further, described that straight to beat lamp source and lower lamp source of beating be LED light emitting diode.
A kind of bicycle lamp device with far and near lamp function of the present invention is beaten lamp source and the projecting beam directly beating lamp source by lower and become low beam respectively and to throw light on and far lamp is thrown light on, be available for users to according to environment, demands of individuals carry out choice for use, and then control far away, the illumination zone of dipped headlights, be different from prior art by need by adjustment lamp source, reflection shield or lampshade distance each other, just can reach object of the present invention, the car light that it also avoid portable structure in the past has complex structure, wear away the problems such as fast, and do not exist in prior art and cannot provide the shortcomings such as suitable illumination zone because location after mobile is uncertain.
