FIG. 2 illustrates an exploded view of a control switch knob for a borderless multi-color backlight, according to one embodiment of the invention. As shown, the control switch knob 200 may include one or more of the following: a knob head 201, a micro-segment 202, a light guide 203, a gasket 204, a light emitting device 205, and a Printed Circuit Board Assembly (PCBA) 206.
A fine tab 202 may be mounted on the knob head 201 for facilitating fine adjustment of the knob. The micro tabs 202 may also provide an assembly base for the knob head 201, light guide ring 203, and PCBA 206, according to one embodiment of the invention. Further, the stop 203 may be mounted on a washer 204, which washer 204 may further be mounted on a PCBA 206.
In one non-limiting embodiment, the light emitting devices 205 may be LEDs. In further embodiments, the light emitting device 205 may include a plurality of light emitting devices 205. In addition, the light emitting devices 205 may emit light of different colors. By way of example and not limitation, a light emitting device that emits red and blue light is shown (e.g., in conjunction with fig. 3B). However, it is to be understood that the present invention may be used with light emitting devices that emit light of any other color. Further, the plurality of light emitting devices 205 of the present invention may emit more than two colors, such as three, four, five … …. In a preferred embodiment, each color may comprise 1 to 3 light emitting devices. For example, in examples where the light emitting devices 205 are LEDs, each color may include 1 to 3 LEDs. The same color LEDs may be placed on the same side of the light guide 203 as is clearly visible in connection with fig. 3B (red and blue side).
The light emitting device 205 may be mounted on the PCBA 206. The PCBA 206 has at least the basic or essential components thereon that support the illumination of the light emitting device. For example, in examples where the light emitting devices 205 are LEDs, the PCBA 206 may support LED power for powering the LEDs and/or PWM control for LED dimming. Gasket 204 may be used to secure the iris diaphragm 203 to the printed circuit board assembly 206. The gasket 204 may have a hole therein corresponding to the size of the light emitting device 205, thereby allowing light emitted from the light emitting device 205 to pass through the hole and then illuminate the bottom of the light guide ring 203. The number of holes may correspond to the number of light emitting devices 205. In one embodiment, the aperture may focus light emitted by the light emitting device 205 onto the light guide 203. In addition, the gasket 204 may also be used for waterproofing. In one non-limiting example, the gasket 204 may be formed from a soft silicone rubber.
The stop 203 may be for mounting in an electronic device panel having an opening. In one non-limiting example shown in fig. 2, the stop 203 includes an opening to receive the knob head 201. The iris diaphragm 203 may be fitted to the fine adjustment plate 202. The stop 203 is used to spread the light emitted by the plurality of light emitting devices 205. In one embodiment, the light guide 203 is used to transmit at least two colors of light emitted by the plurality of light emitting devices. When the various components in fig. 2 are assembled, the top of the light guide ring 203 may be flush or substantially flush with the top of the knob head 201 or below the knob head 201 so that light propagating through the light guide ring 203 may be visible to the user at the knob interface. In one embodiment of the present invention, the light guide 203 includes a structure capable of allowing at least two colors of light to be displayed without a boundary. For example, as shown in connection with fig. 3A and 3B, the light guide ring 203 includes a light transmitting path portion 2032 and a light blocking portion 2034. In one embodiment, the light-transmissive path portion 2032 can comprise a diffusive material. The diffusing material may be any of a variety of diffusing materials available in the art. The diffusing material may comprise a material having a certain roughness, such as ground glass. The diffusing material diffuses the light therethrough to a visually uniform light, and the uniform light can propagate through the diffusing material and ultimately be viewed by a user. In one embodiment, the light blocking portion 2034 can include a non-transparent material to prevent mixing of different colors of light. In addition, the aperture stop 203 may have various desired geometries on its sides. Such a geometry may be useful, for example, for assembly with other components (e.g., without limitation, micro tabs 202).
In a further non-limiting example, the light guide ring 203 may be generally cylindrical, the generally cylindrical light guide ring 203 including light transmissive path portions 2032 separated by light blocking portions 2034 for blocking and propagating light, respectively. For example, the generally cylindrical light guide 203 includes at least two independent light-transmissive path portions 2032 separated by light-blocking portions 2034. The light blocking portion 2034 may be used to prevent light mixing in adjacent light transmission paths. The area of the light transmitting path portion 2032 may be larger than the area of the light blocking portion 2034. In one embodiment, the area of the light transmission path portion 2032 can also be designed to be smaller than the area of the light blocking portion 2034, depending on the specific design and application. The light blocking portion 2034 may have a contour that gradually narrows in the propagation direction of light along the length of the light guiding aperture 203, such that, for example, there is a natural transition between the at least two colors of light, thereby enabling a borderless display of the at least two different colors of light. The gradient may be linear, non-linear, or any other suitable gradient, as the present invention is not limited in this respect.
In fig. 3A and 3B, two light blocking portions 2034 and a light transmitting path portion 2032 are shown. The present invention is not limited thereto and the present invention may include more light blocking portions 2034 and light transmission path portions 2032. The number of light blocking portions 2034 and light transmission path portions 2034 may depend on the number of colors of light to be displayed, for example. For example, in the case where three colors of light need to be displayed, one light blocking portion 2032 may be provided between each adjacent two colors of light, and in this case, 3 light blocking portions 2034 and 3 light transmitting path portions 2032 may be required. Further, fig. 3A and 3B show that two light blocking portions 2034 are provided at positions facing each other by approximately 180 degrees. However, it will be appreciated that the relative positions of the two light blocking portions 2034 may be set at any angle, depending on the lighting effect to be seen.
Fig. 4 illustrates a control switch knob for a borderless multicolor backlight according to an embodiment of the present invention. The transition and connection of the two colors of light transmitted through the light guide ring can be realized without boundary from the knob top panel. Thus, the present application provides a clear indication comprising different colors. This reality may give the user a better visual effect and experience.
The expression "substantially cylindrical" is used herein. The expression is intended to describe that the light guide ring is generally cylindrical in structure and thus includes those that are not strictly cylindrical, such as an elliptical cylinder or the like, or may also include some additional structure such as the periphery of the light guide ring 203 in the present application. Thus, the expression "substantially cylindrical" will be clear to the person skilled in the art.
Furthermore, the light guide 203, herein in the context of the knob 200, may have a generally cylindrical shape and be hollow, in relation to the generally cylindrical outer shape design of the knob. However, the light guide 203 may have any shape, size, configuration, depending on the actual scene of the intended application and the components that fit together with the light guide.
The structure enabling the borderless display of at least two colors of light is presented herein in the context of an illuminable knob in a vehicle. It is to be understood, however, that the present invention is not limited to vehicles nor knob configurations. This configuration of the invention can be used in any application where it is desired to obtain a display of light of different colors without any boundary. Accordingly, applications including such display structures and other scenarios are also within the scope of the present invention. Therefore, the light guide ring structure has strong applicability and expansibility. In addition, the light guide ring structure is realized by ingenious structural design without adding additional components or special expensive materials in the adjusting system, so that the light guide ring structure is very economical and environment-friendly.
Those skilled in the art can make appropriate modifications and adaptations to the embodiments described in detail above without departing from the spirit and substance of the present invention. Therefore, it is intended that claimed subject matter not be limited to the particular examples disclosed, but that such claimed subject matter may also include all implementations falling within the scope of the appended claims, and equivalents thereof.
