Description of the Invention: [Technical Field] The present invention relates to a lighting fixture for a vehicle, and more particularly to a bicycle lamp that complies with the lighting inspection regulations. [Prior technology] In recent years, due to the global concern about environmental protection and energy conservation, coupled with the financial turmoil sweeping across various economic systems, and deeply affecting the family's personal burden, the zero-pollution and fitness bikes are loved by everyone. Popular. Traveling by bicycle, it is natural to pay attention to the solidity of the structure and the brightness of the lighting system to ensure the safety of the rider. For example, Figure 1 shows a national-level bicycle lighting inspection regulation. The distance measured by l〇m is used to detect the illuminance of the HV, LI, R1 equal measuring points and the light receiving area. With the exception of a few products that can be rigorously tested by this regulation, bicycles that have Q can not pass the inspection even through the reflector or diffusing optics. One of the phenomena that failed to pass the test is that the brightness of the Zonel area is too high and glare is generated, which seriously affects the safety of the car to the car. Other phenomena that fail to pass the test are that the HV measurement point is the range that the rider most often looks at, must maintain a brightness above 10 Lux, and the lower area must be no less than 1.5 Lux. Once the tested bicycle luminaire fails to comply with these relevant regulations, it is naturally impossible to enter the international market through inspection. In order to develop the bicycle lamp market, the applicant studied a 3 201040065 headlight that meets international safety standards. SUMMARY OF THE INVENTION The main object of the invention is to provide a bicycle lamp that conforms to the regulations of the lighting system, in particular, a single lamp whose effect is in accordance with international testing specifications. - According to the standards of international testing standards, the illumination of the headlights is as shown in Fig. 2, and there are - cut-off area A, one brightest area B and one bright area. And ❹ ___ contrast zone & 再 between the cut-off area A and the brightest area B. The illumination of this cut-off zone A should be less than 2 Lux, and the contrast zone & This international testing specification also has provisions for (4) distribution. For example, in Fig. 3, along the driving direction F of the bicycle, a predetermined distance S in front of a vehicle lamp 1 is collectively referred to as a low beam region D, and a region exceeding the distance s is called a high beam region E. This distance s refers to an illumination area within two meters of the front of the lamp 100, and the front ten meters of the headlight 1 is regarded as the boundary of the high beam area E. 3 Therefore, the bicycle lamp of the present invention provides the illuminance corresponding to the brightest area B in the low-beam region d and provides a lower than the second degree in the high-beam region E without causing glare affecting the safety of the incoming vehicle. The illumination effect of the present invention is brought closer to the illuminance detection standard value of international regulations. In order to achieve the purpose, the bicycle lamp of the present invention is a light source assembled with a light source, the origin of the light source as a coordinate, the horizontal direction of the light source is the X axis, and the vertical direction of the light source is the γ axis, and the axis The vertical orientation of the junction is the Ζ axis, and an optical structure is placed near the light source of the lamp. t 4 201040065 It is said that the light source is defined as a source of illumination, n package, or it can be a light-emitting diode (ught_Emi rLEeD=LED) or a LED module. Power input light bulb ίϋΛ This light source is installed inside the lamp, for example, 1; the middle position of the cup where the reflection effect is learned first. The cup is mounted on the lamp = fixed, or the wire can be displaced in the lamp. 光学 The optical structure referred to in the present invention includes a lens, a curved seat that illuminates the road surface. b Reflecting surface A2—the reflecting surface above the lens, which is a columnar curved surface extending in the direction of the X-axis, showing a γ-parabolic curve, so that the light source/, the thousand-faced __ίΐ surface The near and far distances form a good contrast effect in the m direction of each hook water. In the opposite: light, the light wave emitted by the shot will be centered: make it form a uniform level in the distant target area; Γ = ΠΓ; the highest brightness area specified by the international inspection specification can be in the vertical direction: the reflected area is quite dim The car lights have the effect of internationally identifiable = than the result of the lighting effect. (4) Comparing the reflected light that achieves the best contrast effect path to the best standard value, it will provide better far-purity light to the near money, and the lens curvature will be refracted to == through the curvature of the lens. The road illumination effect in this area will be slightly worse than the low beam area."曰L according to the sale, the sub-bright area of the international inspection specification needs to be illuminated for the target object. ^There is also a more delicate design of the optical structure. One of the positive lenses of one knife. Because of the refractive curvature edge 5 201040065, this is positive The thickness of the lens is quite large, and the thickness of the lens can be appropriately set, so as not to affect the refractive curvature, and the manufacturing cost is relatively reduced. The present invention is recessed from the outside to the inside in the towel region of the positive lens to form a plurality of segments f. The thickness of the mirror is thinned, and the convergence ability of the positive lens is not affected, or the curved surface that reflects the light to the far road surface is replaced by the original lens and is implemented in the bicycle lamp.

Of course, it is also possible to form a plurality of reflection zones on the reflection sheet by means of molding means or bending means, and the first zone and the third zone are columnar curved surfaces extending in the X-axis direction, so that the light source illuminates the road surface to form uniform water from near to far. = extended silk, and a good contrast effect in the vertical direction (four) ' while the second and fourth zones are reinforcing the near (four) road effect. In addition, the present invention can be provided with a reflective element between the reflective surface (or reflective sheet) disc lens (or curved surface), the radiating element and a flat or columnar curved surface, so that the light can be directed to the reflecting surface ( Or reflective sheet). [Embodiment] In order to help the reader understand the technical contents and features of the present invention, the embodiments will be described in detail in conjunction with the necessary drawings. However, the second example of the invention is limited to the scope of the invention, which is defined by the equivalent or equivalent = method or construction 'implemented on the bicycle's headlights. Due to the variety or style of bicycles and lights, the technical core is not shown in the drawings of the various embodiments: the specific components or structures inside the lamps, and detailed text descriptions 4 6 201040065 Figure 4 is a perspective view of a plurality of embodiments of the present invention. It can be seen from the drawing that the light source 1G of the embodiment is a coffee machine installed inside the lamp, adjacent to the light source 10, and the optical structure 2〇 includes a lens 30 and a lens 3 The reflective surface is 4〇. The lens 30 is a positive lens that cuts off the volume by two, and has a curvature of the lens that causes the light to illuminate the distant road surface. When the light source of the electric energy source generates light, it passes through the lens 3〇 at a human angle, and condensed light 31 required to converge through the curvature of the medium (four) lens, and is irradiated to the near-light region D in front of the lamp 100 shown in FIG. And the road surface of the high beam area E. The illumination requirement of the pavement in the high-beam area is equivalent to the illumination effect of the 2nd bright spot c. Therefore, the light wave refracted by the curvature of the lens will illuminate the distant road surface to achieve a good road lighting effect. In order to clearly understand the technical features of the reflecting surface 40, the light source 10 is used as the origin, the line passing through the horizontal direction of the light source 10 is the χ axis, the line passing the vertical direction of the light source 10 is the γ axis, and the line at the vertical \¥ axis boundary is The Z axis, to outline the space coordinates around the light source 1 。. The reflecting surface 40 is a columnar curved surface extending in the X-axis direction, and has a curve of a parabola of the Ο YZ plane, so that the light of the light source 10 forms a light shape extending horizontally in the distant target area, and achieves a good contrast in the vertical direction. effect. Briefly, the light emitted by the light source 10 illuminates the reflecting surface 40 at an incident angle to generate the reflected light 41, in addition to the light shape of the shell region B of the refracting light 31 to achieve good light and dark. In addition to the contrast effect, it will also provide a road lighting effect that conforms to international inspection specifications for the front light area d of the front light of the vehicle shown in Figure 3. An example of another vehicle light is shown in Figures 5 and 6. In the figure, in addition to retaining the LED as the light source 1 〇 ', the optical structure 2〇' is more delicately designed. The optical structure 20, the lens 3 〇, is also cut 7 201040065, except for the volume of one-half of the positive lens, the convex mirror center area %, inwardly retracted to form a multi-segment of the curved ® 33 ' ' although the lens 3 缩小The thickness, which has no effect on the convergence ability, still allows light to enter the lens 30 and concentrate the desired refracted light 31'. Returning to Fig. 5, the surface of the reflecting sheet 50 is directed toward the lens 30 as a reflecting surface 40, and the other surface is a backlight surface 42, and a plurality of reflecting regions are formed on the reflecting surface 40. The reflection area is provided on the reflection sheet 50 or the reflection surface 40 by one of a molding means or a back folding means. As shown in Figures 7 and 8, the reflecting surface 4() is separated from each other by a first region 5J, a first region 52, a third region 53, and a fourth region 54, and according to FIG. The X-axis orientation is such that the reflection sheet 5 is deflected toward the center by two paragraphs 55, 56, and these reflection areas can be expanded from four to eight. In Fig. 5, the reflection piece % which is multi-stage and deflected toward the center causes the light to repeatedly converge in the central region of the light shape to obtain a strong central luminance. The first region 51 and the third region 53 of the reflection sheet 50 are columnar curved surfaces extending in the z-axis direction, so that the reflected light 41 forms a uniform horizontally extending 〇 shape in the distant target region, and achieves a good contrast in the vertical direction. effect. The second region 52 and the fourth region 54 of the reflection sheet 50 are designed to reinforce the illumination of the near surface, except that a part of the light is directly irradiated on the road surface of the low-beam region D as shown in FIG. The light shape of the road is extended from the underside of the headlights to the pavement of the high-beam area, and the road lighting effect conforming to international standards is obtained. In this embodiment, a reflective element 6〇 is disposed between the reflective surface 40, (or the reflective sheet 5〇) and the lens 3〇, and the reflective element 6〇 has a planar or columnar curved surface, and the incident light is transmitted through the reflective element 6 It is reflected to the first region 51 of the upper reflection sheet 50, and then irradiated in a near or far road surface, etc. 8 201040065 target area. Fig. 9 shows still another embodiment of the bicycle lamp of the present invention. The constitution of this embodiment is similar to that of Fig. 5, except that the design of the semi-lens is replaced by a reflective curved surface 70. In the drawing, the reflective curved surface 7〇 is cut into a half-faced state and located below the reflective sheet 5(), so that the human light is reflected on the near road surface via the reflective curved surface 7〇, and is extended to the far road surface to strengthen Lighting of lower targets. According to the above description, the bicycle lighting effect of the bicycle lamp of the present invention conforms to the international regulations on the detection of the vehicle light, and further develops the international marketing route of the bicycle lamp, which is no longer limited to the domestic market, and the improvement result is obviously excellent. In the prior art, patentable requirements such as novelty and advancement are patented applications.
