Abstract:
Automotive daytime running lights, includes a light source and reflecting plates arranged on a light path of the light source. A substrate is arranged near the reflecting plates. A plurality of reflecting cups is formed on a surface of the substrate. Every reflecting plate faces a corresponding reflecting cup. The reflecting plates can rotate around light source to change the light exiting from the light source. The invention uses a laser source with reflecting plates to make the automotive daytime running lights have high visibility and be aesthetic in appearance.

CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims priority to Taiwanese Patent Application No. 103133181 filed on Sep. 25, 2014, the contents of which are incorporated by reference herein. 
     FIELD 
     The subject matter herein generally relates to an automotive daytime running light. 
     BACKGROUND 
     A conventional automotive daytime running light is a warning light to remind people to pay attention to a running vehicle to decrease accidents. The automotive daytime running light is used to arrange a plurality of LED sources in a line and mounts a reflecting cup to adjust the light. However, the automotive daytime running light has limited visibility. 
    
    
     
       BRIEF DESCRIPTION OF THE DRAWINGS 
       Implementations of the present technology will now be described, by way of example only, with reference to the attached figures. 
       The FIGURE is a cross sectional view of an automotive daytime running light of the present disclosure. 
     
    
    
     DETAILED DESCRIPTION OF EMBODIMENTS 
     It will be appreciated that for simplicity and clarity of illustration, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features of the present disclosure. The description is not to be considered as limiting the scope of the embodiments described herein. 
     A definition that applies throughout this disclosure will now be presented. The term “comprising” means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in a so-described combination, group, series and the like. 
     Referring to  FIG. 1 , an automotive daytime running light includes a light source  10 , a plurality of reflecting plates  20  arranged on a light path of the light source  10 , a substrate  100  paralleled the road of the light path of the light source  10 , a plurality of reflecting cup  30  located above the reflecting plates  20  and a lamp shell  50  located on the substrate  100 . 
     In at least one embodiment, the light source  10  is a blue laser light source. 
     The reflecting plates  20  are spaced each other and arranged on the light path of the light source  10 . In at least one embodiment, the reflecting plates  20  are total reflection mirrors. Every reflecting plate  20  faces to a corresponding reflecting cup  30 . The reflecting plates  20  are rotatable adjusted by a controller (not shown). The controller may be a motor or an electrical components etc. The reflecting plate  20  may be asynchronized. At the same time, only one reflecting plate  20  reflects light of the light source  10 . The controller controls a frequency of the rotation of the reflecting plates  20  to adjust the light efficiency. If the reflecting plates  20  rotate in a higher frequency, a light with a consistent intensity may be visible for people. If the reflecting plates  20  rotate in a lower frequency, a light with a variational intensity may be visible for people. 
     The substrate  100  is made of transparent thermal conductive material and located at top of the reflecting plates  20 . In this disclosure, the substrate  100  is located above the light path of the light source  10  and parallel to the light path of the light source  10 . The substrate  100  includes a first surface  101  and a second surface  102  opposite to the first surface  101 . The first surface  101  is spaced from the reflecting plate  20 . The plurality of reflecting cups  30  and the lamp shell  50  are mounted on the second surface  102 . 
     The plurality of reflecting cups  30  faces to the reflecting plates  20 . Each of the reflecting cups  30  includes a top surface  31  and an inner surface  32  extending from the top surface  31 . The inner surface  32  defines a hole therebetween. The diameter of the hole of the reflecting cup  30  is gradually decreasing from the top surface  31  to a bottom of the reflecting cup  30 . The bottom of the hole is filled with a phosphor layer  40 . 
     The lamp shell  50  is mounted on the second surface  102  and spaced from and covers the reflecting cup  30 . The lamp shell  50  includes a main portion  51  and a plurality of extending portions  52 . The main portion  51  includes a top surface  511 . The plurality of extending portions  52  is located above the top surface  511  of the main portion  51 . The main portion  51  extends from the second surface  102 . The cross section of the main portion  51  is a rectangular. Each of the extending portions  52  includes a connecting portion  521  protruding from the main portion  51  and a top portion  522  protruding from the center of the connecting portion  521 . Every extending portion  52  faces to a corresponding reflecting cup  30 . The width of the extending portion  52  is equal to or larger than that of the reflecting cup  30 , and each of the extending portions  52  is located above the reflecting cup  30 . The center of the top portion  522  is convex. The extending portions  52  have a function of the convex lens to gather the light. 
     In the present disclosure, the light from the light source  10  is reflected by the reflecting plates  20  and the reflecting cup  30  in series and then gathered by the lamp shell  50 . The reflecting plates  20  can rotate fast or slowly. So the frequency of the rotation can be controlled to adjust the light efficiency by the controller. 
     It is to be further understood that even though numerous characteristics and advantages have been set forth in the foregoing description of embodiments, together with details of the structures and functions of the embodiments, the disclosure is illustrative only; and that changes may be made in the details, including in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed. 
     The embodiments shown and described above are only examples. Many details are often found in the art such as the other features of an automotive daytime running light. Therefore, many such details are neither shown nor described. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, including in matters of shape, size and arrangement of the parts within the principles of the present disclosure up to, and including the full extent established by the broad general meaning of the terms used in the claims. It will therefore be appreciated that the embodiments described above may be modified within the scope of the claims.
