[0061]First, please seeFigure 1 to 4 as well asFigure 10 DistanceFigure 1 to 4 A perspective decomposition and stereo combination of the embodiment of the present invention, respectively,Figure 10 The main architecture of the headlights Q is a main architecture. The present invention provides a light lamp device q comprising a carrier pedestal 1, a first reflective structure 2, a second reflective structure 3 (or a conventional reflection structure 3), a first light emitting structure 4, a first Two-brown-emitting structure 5 (or may be called main light structure 5), a lens structure 6, and a shutter structure 7. For example, the first reflective structure 2 and the second reflective structure 3 may be composed of a plurality of different curvature surfaces or a single curved surface, for example by constituting a reflection structure by an elliptical curved surface. Further, the first reflective structure 2 and the second reflective structure 3 are disposed on the carrier base 1, ...

[0085]First, please seeFigure 13 andFigure 14 DistanceFigure 13 andFigure 14 A schematic diagram of the shutter structure 7 of the embodiment of the present invention. It is important to note that the shutter structure 7 provided by the second embodiment can be used to replace the shutter structure 7 provided in the first embodiment. The shutter structure 7 provided by the embodiment of the present invention is preferably applied to the embodiment of the second light emitting structure 5 at the end of the lens optical shaft A, or the second light emitting structure 5 is located below the lens optical shaft A and the first light emitting structure 4 Located or more on the lens optical shaft A. In other words, the distance between the first focus 3a of the second reflective structure 3 to the first focal point 3a of the second reflection structure 3 is larger than the first focal point 2A of the first reflection structure 2. The distance between the lens optical axis A.

[0092]First, please seeFigure 15 to 18 The showing, combined with timelyFigure 19 andFigure 20 As shown, the third embodiment of the present invention provides a shutter structure 7 which can be applied to the lamp device Q, byFigure 13 versusFigure 15 It can be seen that the third embodiment and the second embodiment maximum difference is that the shutter structure 7 provided by the third embodiment has a groove-shaped structure 78 that is integrally with respect to the shutter structure 7, in addition, the third embodiment The first reflection surface 731 and the second reflection surface 732 of the shutter structure 7 provided may be provided substantially parallel to the lens optical axis A. In detail, the shutter structure 7 can include a front cutoff edge 71, a rear side cutoff edge 72, and a top side surface 73. The rear cutoff edge 72 is disposed to each other with the front side cutoff edge 71, and the top side surface 73 can be coupled between the front cutoff edge 71 and ...

Abstract

The invention discloses an automotive lamp device and a shielding plate structure thereof. The shielding plate structure comprises a front cut-off edge, a rear cut-off edge and a top side surface. Therear cut-off edge and the front cut-off edge are correspondingly arranged, the top side surface is connected between the front cut-off edge and the rear cut-off edge, the extending direction of the front cut-off edge facing the rear cut-off edge is defined as an inclined direction, a part of the top side surface is inclined along the inclined direction, and a preset inclination angle is formed between the inclined portion of the top side surface and a horizontal plane or lens axis and larger than 0 degree and smaller than 30 degrees. At least one light ray forms a light and shade cut-off linethrough shielding of the front cut-off edge, so that light collecting effects are improved.

Description

Technical field[0001]The present invention relates to a lamp device, and more particularly to a lamp device having a switching remote lamp state and a shutter structure thereof.Background technique[0002]First, in the design of the existing lights, the high beam is different from the demands and specifications of the low beam, and the high beam is required to achieve a long-distance illumination, and the low beam requires expandment. In order to achieve a wide range of visual ambit. Therefore, in the design concept of the lamp device, the high beam and the low beam are typically separated, that is, their dedicated light cups are responsible for the illumination of the high beam and the low beam. For example, the TW M353845 "Driving Lighting Light Structure" is through the respective separated headlights and the remote lamp module to achieve the switching function of the close lamp and the far light.[0003]Next, the light-emitting module of the existing lamp device can be divided into ...
