Specific embodiment
Specific embodiments of the present invention are further elaborated below.It should be understood that herein to the present invention
The explanation of embodiment is not intended to limit the scope of protection of the present invention.
It as depicted in figs. 1 and 2, is the structural schematic diagram of the light distributing system of bicycle lamp provided by the invention.It is described
The light distributing system of bicycle lamp includes a reflector 1 and a light source 2 being arranged on the reflector 1.It can be with
It is contemplated that the light distributing system of the bicycle lamp further includes other some functional modules, it is reflective as described in being used to assemble
The group arrangement of cup 1, lamp housing, lamp bracket, power supply and electric connection component etc. should be those skilled in the art and are practised
The technology known, no longer illustrates one by one herein.
The light source 2 can be a LED lamp bead.The LED lamp bead should be skill known by those skilled in the art
Art is also referred to as light emitting diode, is a kind of semiconductor electronic component that can convert electrical energy into luminous energy.Those skilled in the art
All known, each light source all should include an optical axis, and optical axis should be the guiding and standard of optical design.At this
In embodiment, the light source 2 has an optical axis 20.
The reflector 1 includes an incidence surface 10 and a reflective surface 11 connecting with the incidence surface 10.It is described
Incidence surface 10 includes a light source providing holes 101.The light source providing holes 101 is for being arranged the light source 2 or allowing described
Light emitted by light source 2 from the light source providing holes 101 project and directive described in reflective surface 11.It will be appreciated by those skilled in the art that
, the profile of the reflective surface 11 by determine light emitted by received light source 2 position, also determine 11 institute of reflective surface
The path of the light reflected, to determine the shape and structure that are formed by hot spot.Therefore, in order to illustrate the reflective surface 11
Profile, by from the section of the vertical optical axis 20 with illustrated along two, the section of the optical axis 20 dimension.
As shown in Figures 2 and 3, on the section along the optical axis 20, the contour line of the reflective surface 11 includes one article the
One reflex arc 111, second reflex arc 112 and a setting are in first reflex arc 111 and the second reflex arc 112
Between changeover portion 113.It is understood, however, that the reflective surface 11 further includes it on the section along the optical axis 20
His structure, such as light-shield cover, mounting structure etc., details are not described herein.First, second reflex arc 111,112 is relative to described
Light source 2 is positive camber, and the radius of first reflex arc 111 is less than the radius of second reflex arc 112, so that from
The different position of the light difference directive that light source 2 is issued, while in the arcuate structure of first, second reflex arc 111,112
Under the action of, the light of the first, second reflex arc 111,112 described in directive is gathered by first, second reflex arc 111,112 respectively
Collect and project, i.e., light emitted by light source 2 is being gathered respectively along optical axis direction.The one of first reflex arc 111
End is crossed section 113 with the side and is connect, and the other end is connect with the incidence surface 10.On the section along the optical axis, described
The center of circle of one reflex arc 111 and the first reflex arc 111 are lived apart in the two sides of the incidence surface 10.In the section along the optical axis
On, the center of circle of second reflex arc 112 and the second reflex arc 112 are lived apart in the two sides of the incidence surface 10, and described second
The center of circle of reflex arc 112 is at a distance from the incidence surface 10 greater than the center of circle of first reflex arc 111 and the incidence surface 10
Distance.One section of the changeover portion 113 is connect with first reflex arc 111, and another section connects with second reflex arc 112
Connect, and the changeover portion 113 extend from first reflex arc 111 to the second reflex arc 112 and this extend perpendicularly to it is described
Optical axis 20 simultaneously extends towards the direction far from the optical axis 20.Due to the presence of the changeover portion 113, so that first reflex arc
111 and second reflex arc 112 emergent light occur layering, i.e. the emergent light of the first reflex arc 111, the second reflex arc 112
Two different irradiation areas are formd, i.e., the first hot spot 3 and the second hot spot 4 as shown in FIG. 6.In the side along the optical axis 20
Upwards, the arc length of first reflex arc 111 is less than the arc length of second reflex arc 112, so that the first reflection
Arc 111 forms the first hot spot 3 and is formed by the second light class 4 less than second reflex arc 112 in the width along the optical axis 20
Width.
Fig. 4 and Fig. 5 are please referred to, it is anti-where first reflex arc 111 on the section perpendicular to the optical axis 20
The contour line in the section of smooth surface 11 is third reflex arc 114, the profile in the section of the 112 place reflective surface 11 of the second reflex arc
Line is the 4th reflex arc 115.The radius of 4th reflex arc 115 is less than the radius of the third reflex arc 114.Described
Three, the 4th reflex arc 114,115 is positive camber relative to the light source 2.It is described on the extending direction along the optical axis 20
The radius of third reflex arc 114 successively decreases towards the direction far from light source 20.On the extending direction along the optical axis 20, the described 4th
The radius of reflex arc successively decreases towards the direction far from light source 20.Due on the section perpendicular to the optical axis 20, described first,
Two reflex arcs 111,112 are arc, can gather to the light from light source 2, play the role of optically focused.
The light distributing system of bicycle lamp provided by the present invention has first, second reflection along optical axis direction
Arc 111,112 and changeover portion 113, perpendicular to optical axis direction have the third, the 4th reflex arc 114,115 so as to
So that it is two separated up and down that the bicycle lamp, which is formed by hot spot, and each hot spot is essentially rectangular.Here " base
This " it is because, because light can scatter during traveling, can be penetrated in the reflector 1 caused by the characteristic of light
Light out, which is formed by around hot spot, forms a brightness compared with aperture, but the still reflector really with illuminating effect
Light emitted by 1 is formed by hot spot.Therefore think that the hot spot is essentially rectangular herein.
The foregoing is merely a prefered embodiment of the invention, is not used to limitation protection scope of the present invention, any in the present invention
Modification, equivalent replacement or improvement in spirit etc., all cover in scope of the presently claimed invention.
