Description

Technical Field

[0001] The utility model relates to a lighting structure, in particular to a lighting structure that can present different information in the same display area. Background Art

[0002] Nowadays, with the booming development of electric vehicles and intelligent vehicles, consumers have higher and higher requirements for the diversity and aesthetics of in-vehicle lighting ornaments. In addition to hoping that the in-vehicle lighting decoration is more delicate, more personalized, and has better lighting effects, consumers also expect to be paired with a lighter and more beautiful structure, and at the same time, they also expect lower energy consumption and greater environmental protection.

[0003] Therefore, in the modern automotive industry, many requirements for in-vehicle lighting ornaments have emerged. These requirements cover applications such as ambient lighting lamp panels around the vehicle, wood-grain-like lighting ornaments, transparent crystal-like central control ornaments, dashboard lighting, in-vehicle entertainment systems, switch lighting, in-vehicle lighting, warning lights, indicator lights, co-pilot seat lighting, and ambient lights, etc. These applications not only provide basic lighting functions but are also closely related to information indication and display functions.

[0004] Most of these in-vehicle lighting applications use LED lighting structures because LED lighting structures have characteristics such as high brightness, energy saving, color changeability, and long life, so they are very suitable for indicating and displaying information. For example, various LED indicator lights installed inside the vehicle are used to indicate vehicle status and function information to the driver, such as not wearing a seat belt, low fuel, engine failure, etc. These indicator lights can also provide warning and reminder information to alert the driver.

[0005] In addition, various LED indicator lights integrated on switches and buttons are used to indicate information about the on or off state of control components. Generally, when the switch is switched to the start state or the off state, the corresponding LED signal will light up to notify the driver of the start or off of a specific function. The dashboard of the vehicle uses a small and medium-sized LED panel to display various driving information, including speed, engine speed, oil pressure, temperature, and mileage, etc., so that the driver can easily master the running state of the vehicle.

[0006] Furthermore, LED lighting units are not only used to provide lighting but are more inclined to be used as information indication or display units. However, due to limited space inside the vehicle, when the sizes, dimensions, and areas of various switches, indicator lights, or panels are extremely limited, how to display more and richer information has become an important technical challenge in the field of in-vehicle LED lighting technology and an urgent problem to be solved.

[0007] For this reason, in view of the disadvantages existing in the prior art, after careful attempts and research, and with perseverance, the utility model inventors finally conceived the "light-emitting structure" of this case, which can overcome the above-mentioned disadvantages. The following is a brief description of the present utility model. Summary of the Utility Model

[0064] The present utility model will be fully understood from the following embodiments, so that those skilled in the art can implement it accordingly. However, the implementation of the present utility model is not limited by the following embodiments; the drawings of the present utility model do not include limitations on size, dimensions, and scale. When the present utility model is actually implemented, its size, dimensions, shape, and scale are not limited by the drawings of the present utility model.

[0065] As used herein, the term "preferably" is non-exclusive and should be understood as "preferably but not limited to". Any step described or recited in any specification or claim may be performed in any order, not limited to the order set forth in the claims. The scope of the present utility model should be determined only by the appended claims and their equivalents, and should not be determined by the embodiments of the implementation examples. When the term "comprising" and its variations appear in the specification and claims, it is an open-ended term without a restrictive meaning and does not exclude other features or steps.

[0066] Most traditional vehicle decorative lighting components use LEDs or bulbs as light sources, and guide the light to the lower part of the partially transparent exterior trim through direct irradiation or in combination with a light guide component. The lighting pattern is completely determined by the pattern of the partially transparent area of the exterior trim, resulting in an inevitable "non"-transparent area pattern in some parts. Therefore, if consumers want to obtain a lighting trim that is as transparent as crystal, the lighting pattern on this trim will only appear when the light source is turned on; when the light source is turned off, this pattern will only faintly emerge or have a completely unclear effect. In principle, it is very difficult to achieve this goal using the structure of traditional or general vehicle decorative lighting components.

[0067] Figure 1 Schematic diagram showing the structure of the first embodiment of the lighting structure included in the present utility model; Figure 2 Schematic diagram showing the first information carried by the optical reflection information structure included in the present utility model. In this embodiment, the lighting structure 100 includes a circuit board 101, a first LED lighting unit 111, a first light guide 121, and an exterior decoration 102, etc. Among them, the first LED lighting unit 111 is disposed on the circuit board 101. After the first LED lighting unit 111 is lit, it will emit LED light 106. The first light guide 121 is disposed on the spacer 109 supported by the frame 108. The color of the LED light 106 emitted includes but is not limited to white, red, blue, yellow, or green, etc.

[0068] The exterior decoration 102 is preferably made of transparent silicone material, PC material, PMMA material, PET material, plastic material, glass material, light-transmitting material, or a combination thereof. The exterior decoration 102 preferably includes a light-transmitting portion 103 and a non-light-transmitting portion 104. In a certain embodiment, the non-light-transmitting portion 104 is preferably formed by making a non-light-transmitting area on the light-transmitting portion 103 in a manner such as but not limited to printing. In a certain embodiment, the light-transmitting portion 103 and the non-light-transmitting portion 104 are formed by using a double-shot injection molding method of light-transmitting and non-light-transmitting plastics.

[0069] The light-blocking portion 104 included in the appearance decorative member 102 is used to form a light-blocking area on the appearance decorative member 102 to shield the underlying circuit traces and electronic components. The light-transmitting portion 103 included in the appearance decorative member 102 is used to form a display area 105 on the appearance decorative member 102. The light-blocking portion 104 can be used to define the range of the display area 105.

[0070] The circuit board 101 also includes a control circuit required to control the first LED light-emitting unit 111, so as to drive and control the first LED light-emitting unit 111. For example, it can drive and control the lighting, extinguishing, brightness, and color of the first LED light-emitting unit 111. The first LED light-emitting unit 111 is preferably a side view LED component. The first LED light-emitting unit 111 preferably uses a small-size, high-brightness, and low-power LED light source, such as but not limited to an SMD LED chip or a COB light source.

[0071] The first light guide 121 is preferably a light guide film (LGF), which is used to guide the LED light 106 emitted from the first LED light-emitting unit 111 to propagate in the direction of the appearance decorative member 102, and convert the LED light 106 from a state of a partial point light source into a state of a partial surface light source during the process. The first light guide 121 is preferably made of transparent silicone, PC material, PMMA material, PET material, COP material, glass material, light guide material, or a combination thereof.

[0072] The first light guide 121 includes a first surface 1211, a second surface 1212, and a third surface 1213. The first surface 1211 and the second surface 1212 are preferably the front and back surfaces of the first light guide 121 respectively. The second surface 1212 is preferably the surface of the first light guide 121 opposite to the first surface 1211. The third surface 1213 is preferably the side surface of the first light guide 121, and the area of the third surface 1213 is smaller than the area of the first surface 1211 or the second surface 1212.

[0073] Preferably, the first light guide 121 includes an optical reflection information structure 131 on the second surface 1212. The optical reflection information structure 131 is preferably formed on the second surface 1212 by means of printing reflective ink, hot stamping, inkjet printing, thermoforming, laser engraving, screen printing, heat transfer printing, die stamping, etching, or a combination thereof, so as to change the optical characteristics of the second surface 1212 and make the second surface 1212 increase its light reflectivity in the direction of the first surface 1211.

[0074] The optical reflection information structure 131 includes a first piece of information 1311, which is preferably color, symbol, number, text, pattern or a combination thereof. When the first LED light-emitting unit 111 is lit and the optical reflection information structure 131 is illuminated, the first piece of information 1311 with a lighting effect can be displayed. When the first LED light-emitting unit 111 is turned off, in the absence of light source illumination, the visibility of the first piece of information 1311 will be reduced, making the first piece of information 1311 appear blurred but still faintly visible, thus generating a semi-hidden or semi-concealed hazy decorative effect.

[0075] The LED light 106 emitted by the first LED light-emitting unit 111 will enter the first light guide 121 from the third surface 1213 of the first light guide 121. After the diffusing effect of the first light guide 121, it enters the optical reflection information structure 131 formed on the second surface 1212, and after being reflected by the optical reflection information structure 131, it exits from the first surface 1211. The first piece of information 1311 carried by the optical reflection information structure 131 will be displayed through the light-transmitting part 103.

[0076] Figure 3 Schematic diagram showing the structure of the second embodiment of the light-emitting structure included in the present utility model. The second embodiment is based on and includes the first embodiment. In this embodiment, the front surface of the first light guide 121, i.e., the first surface 1211, further includes an information layer structure 132, which is preferably formed on the first surface 1211 by means of printing ink, hot stamping, inkjet printing, thermoforming, laser engraving, screen printing, heat transfer, die stamping, etching or a combination thereof.

[0077] The information layer structure 132 is preferably an artwork layer and includes a second piece of information 1321, which is preferably color, symbol, number, text, pattern or a combination thereof. When the first LED light-emitting unit 111 is in the off state, since the information layer structure 132 is located on the front surface of the first light guide 121, i.e., the first surface 1211, the information layer structure 132 will naturally display the second piece of information 1321 under the illumination of ambient light. When the first LED light-emitting unit 111 is lit, after the information layer structure 132 is illuminated, the second piece of information 1321 with a lighting effect will be displayed.

[0078] Figure 4Schematic diagram showing the optical reflection information structure and the first and second information presented by the optical information structure included in the present utility model. Preferably, the optical reflection information structure 131 and the information layer structure 132 correspond to or do not correspond to each other in position, and preferably, the first information 1311 and the second information 1321 correspond to or do not correspond to each other in position. Preferably, the optical reflection information structure 131 and the information layer structure 132 are the same or different in style, and preferably, the first information 1311 and the second information 1321 are the same or different in style.

[0079] In a certain embodiment, the optical reflection information structure 131 is preferably a group of dense light reflection dimples formed by stamping with a steel die. The entire group of dimples presents a triangular style to display the first information 1311. The information layer structure 132 is preferably multiple slanted lines with a color such as but not limited to red formed by inkjet printing. The entire group of slanted lines also presents a triangular style to display the second information 1321.

[0080] For example, when the optical reflection information structure 131 and the information layer structure 132 are illuminated by the LED light 106, the first information 1311 and the second information 1321 with a light-emitting effect will be simultaneously displayed in the display area 105. Assuming that the first information 1311 and the second information 1321 preferably correspond to each other in position, as the LED light 106 carries different colors such as but not limited to white, the superimposed first information 1311 and second information 1321 will specifically present a white triangle pattern with red slanted stripes inside.

[0081] Figure 5 Schematic diagram showing the structure of the third embodiment of the light-emitting structure included in the present utility model. The third embodiment is based on and includes the first and second embodiments. In this embodiment, the light-emitting structure 100 further includes a second LED light-emitting unit 112 and a second light guide 122. The first light guide 121 and the second light guide 122 respectively include a first optical reflection information structure 151 and a second optical reflection information structure 152. The first optical reflection information structure 151 and the second optical reflection information structure 152 respectively carry the third information 1511 and the fourth information 1521.

[0082] The first LED light-emitting unit 111 and the second LED light-emitting unit 112 are respectively disposed on the first surface 1011 and the second surface 1012 of the circuit board 101 and on the same side. The circuit board 101 preferably drives and controls the first LED light-emitting unit 111 and the second LED light-emitting unit 112 individually. The first light guide 121 and the second light guide 122 are also correspondingly disposed on both sides of the circuit board 101 respectively, and guide the first LED light 141 and the second LED light 142 emitted by the first LED light-emitting unit 111 and the second LED light-emitting unit 112 respectively. The colors of the first LED light 141 and the second LED light 142 emitted include but are not limited to white, red, blue, yellow, green, etc.

[0083] Preferably, the first optical reflection information structure 151 and the second optical reflection information structure 152 preferably correspond to each other or do not correspond to each other in position, and the third information 1511 and the fourth information 1521 preferably correspond to each other or do not correspond to each other in position. The first optical reflection information structure 151 and the second optical reflection information structure 152 preferably have the same or different styles, and the third information 1511 and the fourth information 1521 preferably have the same or different styles.

[0084] Figure 6 Schematic diagram revealing the third information presented by the first optical reflection information structure included in the present utility model; Figure 7 Schematic diagram revealing the fourth information presented by the second optical reflection information structure included in the present utility model. In an embodiment, when the first LED light-emitting unit 111 is lit alone, only the first LED light 141 lights up the first optical reflection information structure 151 to separately present the third information 1511 with a lighting effect. When the second LED light-emitting unit 112 is lit alone, only the second LED light 142 lights up the second optical reflection information structure 152 to separately present the fourth information 1521 with a lighting effect.

[0085] In an embodiment, the first optical reflection information structure 151 and the second optical reflection information structure 152 do not correspond to each other in position, and the third information 1511 and the fourth information 1521 have different styles. The style of the third information 1511 is preferably a group of music-related characters and symbols, and the style of the fourth information 1521 is preferably a group of air-conditioning intensity-related characters and symbols.

[0086] When the first LED light-emitting unit 111 is lit alone to emit the first LED light 141, only the first optical reflection information structure 151 will be illuminated, and the third information 1511 with a lighting effect will be separately presented in the display area 105, as Figure 6As disclosed. Therefore, when the second LED light-emitting unit 112 emits the second LED light 142 alone, only the second optical reflection information structure 152 will be illuminated, and the fourth information 1521 with a lighting effect will be separately shown in the display area 105, as Figure 7 disclosed.

[0087] Therefore, by using the light-emitting structure 100 proposed by the present utility model, the first optical reflection information structure 151 and the second optical reflection information structure 152 can be separately illuminated at different positions or the same position in the same display area 105 by switching on and off the first LED light-emitting unit 111 and the second LED light-emitting unit 112, so as to separately show and hide the third information 1511 and the fourth information 1521 with different lighting effects.

[0088] In an embodiment, the first LED light-emitting unit 111 and the first light guide 121 together form the first light-emitting monomer layer, and the second LED light-emitting unit 112 and the second light guide 122 also together form the second light-emitting monomer layer. It should be noted that the implementation of the present utility model is not limited to only the stack of two light-emitting monomer layers, and the implementation of the present utility model also covers the stack of three or four or even more light-emitting monomer layers.

[0089] In an embodiment, the first LED light-emitting unit 111 and the second LED light-emitting unit 112 are preferably still respectively arranged on the first surface 1011 and the second surface 1012 of the circuit board 101, but on different sides. The first light guide 121 and the second light guide 122 are respectively illuminated by the first LED light-emitting unit 111 and the second LED light-emitting unit 112 on different sides. By switching on and off the first LED light-emitting unit 111 and the second LED light-emitting unit 112, the first optical reflection information structure 151 and the second optical reflection information structure 152 can also be illuminated at different positions or the same position in the same display area 105, so as to show the third information 1511 and the fourth information 1521 with different lighting effects.

[0090] Figure 8 Schematic diagram showing the structure of the fourth embodiment of the light-emitting structure included in the present utility model. The fourth embodiment is based on the first and third embodiments and includes the first and third embodiments. In this embodiment, the light-emitting structure 100 further includes a touch sensor layer 110, and the touch sensor layer 110 is incorporated into the light-emitting structure 100 by being attached to the lower surface of the appearance decoration piece 102.

[0091] By setting the touch sensor, the touch sensor layer 110 can correspond to the characters and symbols included in different third information 1511 and fourth information 1521 respectively, and provide corresponding touch functions, so as to achieve the effect of providing multiple control functions with a single touch switch.

[0092] The present utility model provides a novel light guide structure, which combines a transparent appearance decorative member, a side-emitting LED, a light guide film (plate) and a self-reflection pattern structure below it to obtain a crystal-clear light-emitting decorative member. The light-emitting pattern on this decorative member only appears when the light source is turned on; when the light source is turned off, this pattern will only faintly appear or have a completely unclear effect.

[0093] The self-reflection pattern structure is located below the light guide film and can be applied by printing reflective ink on the light guide film, die stamping, etching patterns, etc. Its function is to reflect the light conducted by the LED through the light guide film, so that the user can see the pattern formed by the reflection structure, and there is no need to display the pattern through the traditional local light-transmitting area and non-light-transmitting area. The advantages of this novel light guide structure are as follows:

[0094] (1) A crystal-clear light-emitting decorative member can be obtained, and the light-emitting pattern on this decorative member only appears when the light source is turned on; when the light source is turned off, this pattern will only faintly appear or have a completely unclear effect; (2) Using the light guide film design saves module space and reduces module weight; (3) There is an opportunity to use multiple layers of light guide films with diverse reflected light patterns to create diverse usage scenarios and applications; and (4) Reduces energy consumption.
