locomotive tail warning and license plate illumination. [Prior Art] Press, now the father-pass tool is convenient, especially the most popular locomotive, not only small size, but also does not occupy too much space when parked. In addition, the most important thing is - the point is the lighting fixture [common name ·Lights], the lamps are divided into headlights and rear lights. Especially at night, there are no streetlights installed in some sections. Therefore, the lighting of the locomotive itself is used to illuminate the road through the headlights. It is a warning to the rear to pay attention to the car, and the rear light also has the function of illuminating the license plate to inform the license plate number of the moving vehicle for identification. For example, the construction of the locomotive license plate light of the new announcement No. M266206, with reference to the 苐9 map, is installed on the soil board (c) with a license plate light (b), _ reflecting in the lamp housing Layer (B1), the light is emitted by the refraction of the reflective layer (B1), but it is necessary to mount the license plate lamp (B) on the retaining plate (c), but the following occurs: 1 · It must be assembled by multiple complicated procedures. 2. The screw joint is susceptible to water erosion and oxidative seizure. 3. The license plate lamp (B) is easily exposed to moisture and causes poor contact of the bulb. Another known license plate device, please refer to the tenth figure, which is provided with a license plate lamp (D1) at the lower edge of the rear lamp (D), and the license plate lamp (D1) and the backlight (D) are each; M290848 It is independent and distinguishable by different colors, and there is no concentrating material installed in the license plate lamp (D1). The following conditions also occur during use. · 1. The license plate lamp (D1) has no concentrating material, so Lighting license plates are not performing well. 2. The light of the license plate light (D1) is not directly illuminated by the license plate. Only part of the residual light is used to illuminate the license plate, and the lighting license plate is not effective. For the construction of the patent case of the new bulletin No. 191418 "Multi-room lamp with number plate holder", please refer to the eleventh figure, which is that the lamp (E) is provided with a scented space (E1) in the accommodating space ( E1) is equipped with a first bulb (E2) and a second bulb (E3) which are backward and downward, and a reflector (E4) is mounted on the backward bulb, and the light is reflected by the mirror (E4). However, the second bulb (E3) that illuminates the license plate has no concentrating material, so when the operation is used, the second bulb of the illuminated license plate is not blocked by the concentrating object, and the light cannot be reflected, the second The light of the bulb (E3) is a diffusing fork type, but the light cannot be collected, so the light shining on the license plate seat is weak and the lighting license plate is not effective. [New content] The present invention provides a locomotive rear lamp structure, which is attached to the lamp holder a of the rear lamp and has a reflective sheet group, and is provided with a first reflecting sheet in the first illuminating element group, and reflects the first illuminating element.

The backward concentrating curved surface of the piece (21B) concentrates the scattered light rays through the condensing curved surface and emits in the same direction, and the light illuminates the color of the outer casing of the lamp holder (IB), so as to warn the rear car to pay attention, and The light of the second illuminating element (32B) is concentrated by the downward condensing curved surface of the second reflecting sheet (22B), and the scattered light is concentrated through the condensing curved surface and emitted in the same direction, and the light is irradiated to the baffle (A) ) On the license plate number (A1), the license plate number (A1) is obvious through the concentrated illumination of the light, which is easy to identify clearly. The fourth embodiment of the present invention, as shown in the seventh figure, is provided with a reflector group (2C) and a light-emitting component (3C) in the lamp holder (IC) of the backlight, wherein: the lamp holder (ic) is provided There is a fixing portion (llc), and the fixing portion (llc) has no groove (111C), and the groove (11 ic) has a fitting portion (丨12C) therein. The reflective sheet group (2C) is a concentrated curved surface, which is a first reflecting sheet (21C) and a second reflecting sheet (22C), respectively, and the first reflecting sheet (2 ic) is set in the socket (lc). The second retroreflective sheeting (22C) is provided with a fixing portion (23C), and the fixing portion (23C) is provided with a convex portion (231C). The light-emitting elements (3C) are respectively a first light-emitting element (31C) and a second light-emitting element (32C), and the first light-emitting element (31C) is placed on the first light-reflecting sheet: M290848 " (21C), and The two light-emitting elements (32C) are placed on the second light-reflecting sheet (22C). A rearward collecting surface ' of the first reflecting sheet (21C) is disposed in the socket (1C), and the first light-emitting element (31C) is disposed on the first reflecting sheet (21C), and is further disposed in the socket (1C). A downwardly convex curved surface of the second retroreflective sheeting (23C) is disposed, and the second light emitting element (32C) is disposed on the second retroreflective sheeting (22C). Next, the convex portion (231C) of the fixing portion (23C) of the second retroreflective sheeting (22C) is inserted into the fitting portion (112C) of the recess (111C) of the fixing portion (11C) of the socket (1C), Form a chisel. When in use, as shown in the eighth figure, when the locomotive is driving at night, when the knight turns on the light while lighting the light-emitting element (3C) of the lamp holder (1C) of the rear lamp, the illuminating element of the lamp holder (1C) 3C) and irradiate in a backward and downward manner. The housing of the lamp holder (1C) is made of a light-transmitting material, and a warning color is applied to the outer casing for light to illuminate the warning color, when the light of the first light-emitting element (31C) is reflected by the first light. The rearward concentrated surface of the piece (21C) concentrates the scattered light through the collecting surface and emits in the same direction. This light illuminates the color of the casing of the lamp holder (1C) to warn the rear car to pay attention. The light of the second illuminating element (32C) is concentrated by the downward condensing curved surface of the second reflecting sheet (22C), and the scattered light is concentrated through the condensing curved surface and emitted in the same direction, and the light is irradiated to the baffle (A) ) On the license plate number (A1), the license plate number (A1) is obvious through the concentrated illumination of the light, which is easy to identify clearly.
