[0025] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.
[0026] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. During actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.
[0027] Ambient lighting is a lighting device used inside a car that can create a specific atmosphere or emotional effect, providing passengers with a comfortable and warm driving environment. Ambient lighting can be installed in different locations of the vehicle, such as the roof, floor, door interior panels, etc., to provide different lighting effects and atmospheres.
[0028] The existing mood lighting effects usually change the intensity of light by adjusting the brightness to create different atmospheres. Some mood lighting fixtures support adjusting the color temperature from warm tones (such as orange) to cool tones (such as blue) to meet the needs of different scenes. Lamps with RGB LEDs can produce rich colors by mixing red, green, and blue. However, these mood lighting effects are all static lighting effects and it is difficult to achieve dynamic lighting effects.
[0029] like Figure 1 , 2 As shown, an ambient light structure is provided, including a light-transmitting decorative plate 10 , a first light guide strip 20 , a second light guide strip 30 and a light source 40 .
[0030] Translucent decorative panel 10, atmosphere light The main feature of the translucent decorative panel 10 is the addition of a translucent design on the decorative panel so as to transmit light through the panel, thereby creating a unique atmosphere effect.
[0031] The first light guide strip 20 is arranged on the inner side of the light-transmitting decorative plate 10. The outer side in the present application refers to the side facing the ambient light, generally the cockpit side, and the inner side is the side opposite to the outer side. The light guide strip is an optical device, usually made of transparent or translucent material, used to guide light to the desired position. The main purpose of this device is to transmit light in its length direction and evenly distribute it at the outlet end.
[0032] The light source 40 is disposed at the end of the first light guide strip 20. A single light source 40 and a single light guide strip can constitute a light emitting body, wherein the light source 40 is an RGB LED (red, green, and blue LED), which is a light emitting diode that can emit light of three basic colors: red (R), green (G), and blue (B). By adjusting the brightness of these three colors, the RGB LED can generate a variety of different colors of light, thereby achieving a rich color effect.
[0033] The light-transmitting decorative plate 10 is arranged so that the brightness of the light passing through the light-transmitting decorative plate 10 gradually increases from one end to the other end of the first light guide strip 20. The gradual change in brightness can be achieved by arranging the thickness, light transmittance, position, etc. of the light-transmitting decorative plate 10. In this way, a shooting star effect with gradually changing brightness can be achieved.
[0034] like Figure 1 , 2 As shown, two light sources 40 are provided and are disposed at both ends of the first light guide bar 20. Since the farther away from the light source 40 on the light guide bar, the darker the brightness, the light sources 40 are arranged at both ends of the first light guide bar 20 to make the light emission more uniform, and the two light sources 40 can be controlled separately to achieve a variety of color changes.
[0035] like Figure 1 , 2 As shown, it also includes a second light guide bar 30 arranged side by side with the first light guide bar 20, and the light source 40 is provided with two and is respectively arranged at the ends of the first light guide bar 20 and the second light guide bar 30, and the end of the first light guide bar 20 close to the light source 40 is adjacent to the end of the second light guide bar 30 far from the light source 40. The second light guide bar 30 is arranged side by side and close to the first light guide bar 20, and the light of the first light guide bar 20 and the second light guide bar 30 arranged side by side can be mixed with each other, for example, the first light guide bar 20 emits red light, and the second light guide bar 30 emits blue light, and purple light can be formed at this time. The brightness of the first light guide bar 20 and the second light guide bar 30 can be adjusted separately, and the light effect of the atmosphere light can be changed by changing the brightness of the two. The light effect of the atmosphere light can also be changed by the brightness difference of each position on the first light guide bar 20 and the second light guide bar 30, such as the flowing light effect.
[0036] In the first embodiment, the thickness of the light-transmitting decorative plate 10 gradually decreases from the position close to the light source 40 of the first light guide bar 20 to the position far away from the light source 40 of the first light guide bar 20. The lower the thickness of the light-transmitting decorative plate 10, the better its light transmittance, so that a light effect with gradually increasing brightness from the position close to the light source 40 of the first light guide bar 20 to the position far away from the light source 40 of the first light guide bar 20 can be formed on the light-transmitting decorative plate 10, and the appearance of this light effect is similar to the track of a meteor across the night sky.
[0037] In the second embodiment, the light transmittance of the light-transmitting decorative plate 10 gradually increases from the position close to the light source 40 of the first light guide strip 20 to the position far away from the light source 40 of the first light guide strip 20. Similarly, as the light transmittance of the light-transmitting decorative plate 10 gradually increases, it can also form a strip pattern with gradually increasing brightness, that is, a shooting star light effect.
[0038] In the third embodiment, the first light guide strip 20 gradually approaches the light-transmitting decorative plate 10 from the end close to the light source 40 to the end far from the light source 40. The farther away from the first light guide strip 20, the darker the light effect formed on the light-transmitting decorative plate 10. In this way, the control of the spacing can also form a strip pattern with gradually increasing brightness, that is, a shooting star light effect. Among them, the first, second and third embodiments can be used alone or in combination.
[0039] like Figure 1 , 2 As shown, one end of the first light guide bar 20 close to the light source 40 is adjacent to one end of the second light guide bar 30 far from the light source 40. The left light source 40 in the figure corresponds to the first light guide bar 20, and the right light source 40 in the figure corresponds to the second light guide bar 30. That is, the light sources 40 on the first light guide bar 20 and the second light guide bar 30 are arranged relatively. In this way, due to the characteristic that the farther away from the light source 40 on the light guide bar, the darker the brightness, when the first light guide bar 20 and the second light guide bar 30 have different brightness, in combination with the structures of embodiments one, two, and three, a bright spot can be formed on the light-transmitting decorative plate 10. As the brightness on the first light guide bar 20 and the second light guide bar 30 changes, the light spot can also move along the direction of the light guide bar. The bright spot is regarded as the head of a meteor, and other areas with weaker brightness are regarded as the tail of a meteor, so that a flowing meteor light effect or a flowing water light effect can be formed. The flow light effect in the prior art is usually composed of a series of closely arranged LED lights, which are arranged in a specific direction to form a line or curve. Each LED unit can usually control the color and brightness independently, and the light effect is lit one by one along the direction of the LED arrangement to form a flow light effect. In the present application, the flow light effect can be achieved by only two light sources 40 and light guide strips, and the flow light effect is more uniform.
[0040] For example, when the atmosphere light is activated, the light source 40 of the first light guide bar 20 emits green light and the brightness value gradually increases from 1-10, while the light source 40 of the second light guide bar 30 emits red light and the brightness value gradually decreases from 10-1, so that a yellow light spot flowing along the light guide bar can be formed, and the color depth of the yellow light spot will gradually change. Then the light source 40 of the first light guide bar 20 and the light source 40 of the second light guide bar 30 cycle this action to achieve a continuous shooting star light effect.
[0041] like Figure 2As shown, when the yellow light spot reaches the critical point 50, the brightness of the light source 40 of the first light guide strip 20 and the light source 40 of the second light guide strip 30 is controlled so that the yellow light spot gradually dims and turns off to avoid sudden changes in light effect. The critical point 50 is not a specific structure on the ambient light, but corresponds to a position on the light-transmitting decorative plate 10.
[0042] The light-transmitting decorative plate 10 is provided with a strip-shaped light-transmitting area at a position corresponding to the light guide bar, and the width of the strip-shaped light-transmitting area gradually increases from a position close to the light source 40 of the first light guide bar 20 to a position far away from the light source 40 of the first light guide bar 20. The strip-shaped light-transmitting area can be realized by spraying laser engraving, INS film, etc., so as to realize the shape of the meteor and the tail.
[0043] The light-transmitting surface of the light-transmitting decorative plate 10 is made of a haze material. The light-transmitting decorative plate 10 has a haze base material, which can make the tail of the meteor light effect appear blurred after lighting up. At the same time, the introduction of haze can produce a soft and uniform light scattering effect, making the light softer and avoiding strong reflections and glare. Haze can also help to block some small defects or scratches on the surface of the material, making it look more uniform in the light-transmitting state. When used inside a vehicle, the light-transmitting decorative plate 10 made of haze can reduce the glare caused by strong light and improve the driving and riding comfort.
[0044] The light source 40 is connected to a control device for adjusting its color and brightness. The light source 40 includes a PCB board and lamp beads arranged on the PCB. The PCB board is connected to the brightness control device and the color control device through signals, and then the color and brightness of the light source 40 can be controlled accordingly. When the vehicle door opening signal, ignition, turning, reversing and other CAN signals are transmitted to the control device through hard wires, the control device converts the corresponding signal into a LIN signal and transmits it to the light source 40. The light source 40 will respectively execute the corresponding color and brightness signals, and cycle according to the set speed and time. When the door is closed, the atmosphere light exits the door opening warning function and returns to the preset color and brightness. The control device is the vehicle host.
[0045] The first light guide strip 20 and the second light guide strip 30 are respectively provided in plurality, so that a plurality of meteor-like equivalents can be formed on the vehicle interior trim panel, forming a meteor cluster equivalent.
[0046] The utility model also provides a vehicle, comprising the above-mentioned atmosphere light structure. The above-mentioned atmosphere light structure can be installed around the vehicle instrument panel, door trim, around the skylight, under the floor, and the roof position without a skylight structure, and a dynamic popular starry sky roof effect can be formed at the roof position without a skylight structure.
[0047] The utility model proposes an atmosphere lamp structure and a vehicle. In the above scheme, the gradual change of light brightness is achieved by changing the transmittance, position and thickness of the translucent decorative panel, thereby achieving a lighting effect similar to a meteor. At the same time, richer lighting effects can also be produced by changing the color and brightness of the light source.
