Description

Technical Field

[0001] The utility model relates to the technical field of vehicle lamps, and specifically, to an optical module, an optical system and a vehicle lamp with a transparent OLED structure. Background Art

[0002] For traditional uniform surface-emitting light sources, such as the OLED structure, due to the relatively low brightness itself, in vehicle lamps, usually only a single area is lit as a supplement to the signal lamp function. In this case, there are often great limitations on the shape of vehicle lamps. The OLED structure implemented by the utility model and the reuse of traditional functional windows can not only meet the optical requirements but also reflect the uniform light emission and dynamic display effects of the OLED structure.

[0003] Traditional OLEDs are opaque and have low brightness. Therefore, additional optical systems in other areas are still required to meet the light intensity requirements, which will result in a relatively large area for the functional area using OLEDs, restricting the diversified design of the vehicle lamp shape.

[0004] The utility model uses a transparent OLED, which is arranged in front of traditional optical systems (such as reflectors, light guide bars, and thick-wall optical components, etc.). On the basis of meeting the light intensity requirements, the characteristics of the OLED can also be presented in the same area, reducing the area requirements and providing convenience for free and diversified styling.

It should be noted that those of ordinary skill in the art can make several changes and improvements without departing from the concept of the present utility model. These all belong to the protection scope of the present utility model.

[0041] Example 1:

[0042] As Figure 1 shown, this embodiment provides an optical module with a transparent OLED structure, including: a light source 1, an optical component, an OLED structure 2, an optical component bracket 7, and an OLED bracket 8; the OLED structure 2 is disposed on the OLED bracket 8, and the optical component is disposed on the optical component bracket 7; the light source 1 is disposed at the light incident end of the optical component, and the OLED structure 2 is disposed at the light emitting end of the optical component; the OLED structure 2 is a transparent structure; the optical component and the OLED structure 2 share a light emitting surface; when only the OLED structure 2 is lit, the light emitted by the OLED structure 2 exits from the light emitting surface; when only the light source 1 is lit, the light emitted by the light source 1 reaches the OLED structure 2 after being adjusted by the optical component, and then exits from the light emitting surface through the OLED structure 2.

[0043] The optical component is a thick-wall component 3; the light emitted by the light source 1 enters the thick-wall component 3 through the light incident surface of the thick-wall component 3, and then exits from the light emitting surface of the thick-wall component 3 to the OLED structure 2. A condenser 6 is disposed on the light incident surface of the thick-wall component 3, and the light emitted by the light source 1 enters the thick-wall component 3 through the condenser 6.

[0044] A plurality of OLED structures 2 are provided, and the plurality of OLED structures 2 are arranged and disposed on the OLED bracket 8. The OLED structure 2 is provided in three, namely a first OLED structure 201, a second OLED structure 202, and a third OLED structure 203.

[0045] This embodiment also provides an optical system, including the above-mentioned optical module with a transparent OLED structure. This embodiment also provides an automotive lamp, including the above-mentioned optical system.

[0046] Example 2:

[0047] As Figure 2 shown, the difference between this embodiment and Embodiment 1 is that the optical component is a reflector 4; the light emitted by the light source 1 reaches the OLED structure 2 after being reflected by the reflector 4.

[0048] Example 3:

[0049] As Figure 3 shown, the difference between this embodiment and Embodiment 1 is that the optical component is a light guide bar 5; the light emitted by the light source 1 enters the light guide bar 5 through the light incident end of the light guide bar 5, and the light exiting from the light guide bar 5 reaches the OLED structure 2.

[0050] Example 4:

[0051] Those skilled in the art can understand this embodiment as a more specific description of Embodiments 1 to 3.

[0052] This embodiment provides an automotive lighting system using a transparent OLED. The surface light source is arranged in front of the optical system. The surface light source is a transparent white-light-emitting OLED, and the optical system is a signal light optical system, which may include an LED light source and a transparent thick-wall light guide structure.

[0053] Since the OLED used in this embodiment has a high transmittance, the light emitted by the optical system still meets the optical regulation requirements of vehicle lamp signal lights after passing through the OLED structure 2. Synchronously, when the optical system is turned off, the surface light source can be lit independently to achieve multi-functional single-window multiplexing.

[0054] The optical system has a separate light source, which may be an automotive-grade LED. Through a transparent thick-wall part with a condenser structure, uniform lighting and a required light intensity distribution are achieved. For different functional opening shapes, the optical system may be an optical system such as a light guide bar, a reflector, a condenser, and an atomizing material.

[0055] The surface light source is a transparent white-light OLED, which can emit uniform white light when powered on and has a high transmittance itself. And it can be pixelated and divided to achieve specified area lighting according to requirements, forming an animation effect.

[0056] In this embodiment, a new type of OLED structure is arranged directly in front of the functional area to achieve personalized displays such as animations. And because this OLED has a high transmittance, the rear optical system can still achieve the signal light function.

[0057] The utility model arranges a transparent OLED structure directly in front of the functional area to achieve personalized displays such as animations. And because the OLED structure has a high transmittance, the rear optical system can still achieve the signal light function.

[0059] The specific embodiments of the present utility model have been described above. It should be understood that the present utility model is not limited to the above specific embodiments, and those skilled in the art can make various changes or modifications within the scope of the claims, which do not affect the essence of the present utility model.
