INSTRUCTIONS: [Technical field to which the invention pertains] and particularly related to the present invention relates to a vehicle retroreflective device for an active reflective warning device. [Prior Art] Commonly used passive reflectors include traffic signage, traffic signs, and safety reflectors for vehicles. These passive reflectors are often equipped with a reflective material on the device. After the light is applied to the reflective material, the device can be illuminated by means of reflection. However, when the intensity of the illumination source is weakened, the reflection effect of the passive reflection device is also lowered, so that the illumination display cannot be clearly seen. Especially when the passive reflector is applied to the traffic indicator kanban, if the intensity of the illumination source is weak, it cannot be effectively illuminated. Thus, the enemy may not be able to clearly identify the indications of the traffic signs and affect their judgment. If it is serious, it may even cause a traffic accident. In addition, 'this type of passive reflector must wait until there is light to illuminate it'. It has no warning effect in the absence of light. Therefore, its warning range and warning distance are limited, and drivers often need to approach it. After a certain distance, the prompt of the passive reflector can be seen. In order to effectively improve the warning range and warning distance of the vehicle reflective device, an active reflective warning device is proposed. Referring to FIG. 1 , the conventional reflective warning device 10 can be divided into a reflective area 110 200929110 and a light-emitting area. 120' wherein the reflective area 110 can surround the light-emitting area Ho. The light-emitting area 120 of the conventional reflective warning device 100 is provided with at least one light-emitting element 122. The reflective area 110 has a reflective film to reflect the light of the external light source, and the light emitted by the light-emitting element 122 cannot penetrate the reflective area 110. It can be emitted through the light-emitting area 120. Although the conventional reflective warning device 1 can actively emit light by using the built-in light-emitting element 122, since the light-emitting area 12 has only a light-emitting function and does not have a reflective performance, the area covered by the reflective film 11〇 is reduced. The function of the reflective area u〇 of the conventional reflective warning device is reduced. SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide an active reflective warning device for actively alerting a driver outside a certain distance and for efficiently reflecting light.

BRIEF DESCRIPTION OF THE DRAWINGS The spirit of the present invention will be clearly described in the following drawings and detailed description, and those of ordinary skill in the art will be able to change the teachings of the present invention. And modifications may be made without departing from the spirit and scope of the invention. Referring to Figures 2A and 2B, a side view and a front view, respectively, of a preferred embodiment of the active reflective warning device of the present invention are shown. The active reflective warning device 200 includes a light transmissive cover 21, a 7 200929110, a translucent reflective sheet 220, and a light emitting unit 230. The light transmissive cover 210 has a light transmissive surface 212. The translucent retroreflective sheeting 220 is a translucent reflective sheet. For example, the translucent retroreflective sheeting 220 is a glittering cube-corner retroreflective sheeting produced by the method of U.S. Patent No. 5,770,124, or Other reflective sheets conforming to ASTM: D 4956-04, the front surface 222 of the light transmissive reflector 220 is engraved with a microcrystalline cube-corner shape pattern to reflect external light, and in addition, the light is more transmissive. The back surface 224 of the retroreflective sheeting 220 is transmissive.被动 The passive light receiving angle of the light transmissive reflector 220 is from 1 to 18 degrees. The angle of observation of the passerby is preferably between 35 and 115 degrees. This is the active reflective warning device 200. The preferred warning angle for the light source. In contrast, the active reflective warning device 2 of the present invention is equipped with a light-emitting element 234, and the angle of observation of the passerby can be increased to 180 degrees, so that the warning angle can be expanded to reach 18〇. Degree is no dead angle. In addition, the light emitted from the light-transmitting surface 212 by the light-emitting unit 230 can also actively prompt the driver, so that the active-reflective warning device 200 can alert the driver in advance, and whether it is passive reflection or active illumination, its warning The area is a complete light transmissive surface 212. The back surface 224 of the light-transmitting reflector 220 is a light-transmissive surface 212 attached to the light-transmitting cover 21, and the light-transmitting reflector 22 is preferably a light-transmissive surface 212 that completely covers the light-transmitting cover 210. The light-emitting unit 230 can be disposed in the light-transmitting cover 210, and the light emitted by the light-emitting unit 23 can be emitted through the light-transmissive surface 212 and the light-transmitting reflective sheet 220. In other embodiments, the light transmissive surface 212 can be an opening, and the light transmissive reflector 220 can directly seal the opening of the light transmissive surface 212, and can also have the same effect as the light transmissive outer cover of the 200929110 cover 210. The light emitting unit 230 can include a circuit board 232 fixed to the light transmissive cover 210, a light emitting element 234 disposed on the circuit board 232, and a power source 236 connected to the circuit board 232. In this embodiment, the light-emitting element 234 can be a light-emitting diode, and the light-emitting element 234 is preferably disposed at a center position corresponding to the light-transmitting retroreflective sheet 220. The power source 236 can be a direct current, such as a solar cell, and the power source 236 of the solar cell is preferably disposed on top of the light transmissive cover 210 to receive solar energy.

Alternatively, in other embodiments, lens set 240 can also be directly packaged onto light-emitting element 234 in the form of a collimator.主动Because the active reflective warning device 200 uses the light-transmitting reflector 220, the light emitted by the light-emitting unit 23 can directly pass through the light-transmitting reflector 220, and the transparent surface 212 is generally required as in the prior art. It is divided into a reflective area and a light-emitting area, and therefore, the complete light-transmissive area of the light-transmitting retroreflective sheeting 220 can be effectively retained. The light emitted by the light-emitting unit can also be emitted to the light-transmitting surface 212, so that the active light-reflecting warning device 2 can achieve the effect of warning before the handle is not approached. The active anti-light alarm device 200 can be applied to luminaires of vehicles such as directional lights, brake lights, and warning reflectors. 200929110 Referring to Figures 3A and 3B, there are shown side and front views, respectively, of another preferred embodiment of the active reflective warning device of the present invention.
