With the advancement of automotive lighting t, the trend of automotive lighting can be seen that the lighting function is stronger, more, more 'electricity, more volume, more convenient to the car factory design lights" will be the new mainstream of future car lights development . The traditionally light design is to place the focus of a circular mirror by placing a light element such as a silk lamp or (four) material. The light emitted by the re-emitting S piece is collected by the elliptical mirror through a lens or the like to emit light in parallel to a beam of a certain cross-sectional shape. Among them, in particular, the beam formed by the light emitted by the lamp is specified and limited in terms of the cross-sectional shape at a certain distance from the car, including the shape and size. Therefore, before the light passes through the lens, it is conventional practice to add a baffle having an opening of a certain shape to form a cross-sectional shape of the light beam in accordance with the regulations of the relevant lamp. The following is an example of a conventional lamp. FIG. 1 is a schematic perspective view of a conventional lamp. Please refer to Figure j. The lamp 100 includes a light emitting element 110, a baffle 20, a lens 13A, and an ellipsoidal mirror 140. Wherein, the light-emitting element 11 is, for example, a halogen bulb, which is disposed in the ellipsoidal mirror 140, and the lens 13 has a diameter of 5 12943 6? (0wf.doc/g is placed on the optical path behind the baffle 120. Further, The baffle 120 is located at the optical axis of the ellipsoidal mirror 140. The illuminating element 110 is used as a light source for the illuminating light 100. When the illuminating element 110 is activated, it emits light in all directions. The emitted light strikes the surrounding illuminating element 110. After the ellipsoidal mirror 140 is reflected, it is reflected to the focus of the ellipsoidal mirror 140. Since the damper 120 is located at the focus of the ellipsoidal mirror 140, the light partially reflected to the focus is blocked. The occlusion of the board 120. In other words, only part of the light can pass through the baffle 140 and exit through the lens 130, so that the shaped light is obtained. Therefore, the conventional lamp provides the conforming vehicle according to the principle. Light beam of a specific cross-sectional shape of the lamp law. However, it can be clearly observed from Fig. 1 that the light emitted by the light-emitting element u〇 not only undergoes reflection by the elliptical mirror H〇, but also causes energy loss. Moreover, in order to cover most of the light for the support of the light beam, the light utilization rate of the conventional lamp is poor. [Invention] The object of the present invention is to provide a vehicle. The lamp is adapted to enhance the light utilization rate of the lamp. The invention provides a lamp suitable for providing a light beam along a direction of illumination, wherein the beam has a predetermined shape in a vertical direction of illumination. The lamp includes a one-side type light-emitting element and a lens system. The surface-type light-emitting element has a light-emitting surface, and the shape of the light-emitting surface corresponds to a predetermined shape. Further, the lens system is disposed on the optical path of the surface-type light-emitting element. Wherein, the light emitted by the surface-type light-emitting element passes through the lens system to form the aforementioned light beam. 6 doc/g

And further, the light utilization rate of the vehicle is greatly increased. The above and other aspects, features and advantages of the present invention will become more apparent from the following description. [Embodiment] Fig. According to this (four) - the three-dimensional representation of the actual turn of the light, the light beam emitted by the two lights is vertical, and the light of the car is two] a preset shape of eight. In order to achieve the above-mentioned eye lens system 22〇. One surface type light-emitting element plus one of the two is placed on the surface-type light-emitting element 21.

At the same time, the two tamper 210 has a shape for providing the light X-ray surface S, that is, corresponding to the aforementioned pre-doc/g 1294363⁄4. == The cross-section shape of the light beam provided by the surface-type light-emitting element 210 is W© s The shape, that is, the aforementioned preset shape Μ 来 来 , 来 来 来 来 面 面 面 面 面 面 面 面 面 面 面 面 面 面 面 面 面 面 面 面 面 面 面 面 面 面 面 面 面 面 面 面 面 面 面 面 面 面2 is shown. In other words, in the lamp 200 of the present embodiment, the light emitted by the surface-type light-emitting element 21 不 does not need to pass through other optical elements to shape the cross-sectional shape, thereby reducing the brightness attenuation caused by the shaping process, and further Increase the light utilization rate of the lamp 2 。. Shape A1 can be. Of course, the preset shape A1 is not limited to that shown in Figure 2, and should be changed according to regulations and other design requirements. For example, as shown in FIG. 3, the surface type light-emitting element 21G may be a light-emitting diode, an organic electro-active light-emitting element, a field emission display element, or any other suitable surface-type light-emitting element. The shape of the light emitting surface s of the element 210 corresponds to the preset non-surface type light emitting S piece 21G, which may be arranged by a plurality of point light sources (for example, light emitting diode chips) into a predetermined shape A1 and then packaged. Alternatively, the planar light-emitting element 210 may be composed of a single light-emitting diode wafer as long as the light-emitting surface corresponds to the predetermined shape A1. In addition, since the surface-type light-emitting element 210 mainly emits light from the light-emitting surface S, light may not be emitted with respect to the back surface of the light-emitting surface S. Therefore, the light emitted by the surface-type light-emitting element 210 can be directly emitted outward, not only lifting. Light utilization, which reduces the difficulty of optical design. In addition, the lamp 200 of the embodiment may include a support base (not shown), and the surface-type light-emitting element 210 and the lens system 220 may be disposed on the support base. Additionally, lens system 220 can be comprised of one or more lenses as desired.
