Detailed Description

In order that the above objects, features and advantages of the utility model will be readily understood, a more particular description of the utility model will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings.

As shown in fig. 1, an embodiment of the present utility model provides an atmosphere lamp, which includes a first light emitting element 1, a second light emitting element 2, a light guiding element 3 and a decoration board 4, wherein the first light emitting element 1 and the second light emitting element 2 are respectively disposed at two ends of the light guiding element 3, the light guiding element 3 is located on a common light emitting path of the first light emitting element 1 and the second light emitting element 2, and the light guiding element 3 is configured to emit light emitted by the first light emitting element 1 and the second light emitting element 2 onto the decoration board 4.

Specifically, the atmosphere lamp comprises a first light emitting part 1, a second light emitting part 2, a light guide part 3 and a decoration plate 4, wherein the first light emitting part 1 and the second light emitting part 2 can emit lights with different colors and different brightness and spread in the light guide part 3, and the lights emitted by the first light emitting part 1 and the second light emitting part 2 are emitted onto the decoration plate 4 through the light guide part 3, so that the surface light emitting effect is realized, and further, the flow change of the color of the atmosphere lamp can be realized with low cost (about the cost of the existing atmosphere lamp 1/3). Because the atmosphere lamp can be arranged in different areas in the vehicle to meet different requirements, for example, the illumination on the pedal plate can provide more night safety, the illumination on the ceiling can create a more spacious feel in the vehicle, and unique driving and riding experiences can be created for passengers through the surface luminous effect and the color flow change.

For example, when the first light emitting element 1 and the second light emitting element 2 both emit red light, the light guiding element 3 is red in color, when the first light emitting element 1 changes to green light, the light guiding element 3 near the first light emitting element 1 will be green light, and a part far away from the light guiding element will be yellow light by mixing green light and red light, the light guiding element 3 near the second light emitting element 2 will still be red light, and as the green light of the first light emitting element 1 is enhanced, the distribution areas of green light, yellow light and red light in the light guiding element 3 gradually change to spread to the second light emitting element 2.

The first light emitting element 1 and the second light emitting element 2 generally include electronic components such as a PCB (Printed Circuit Board ), an LED (LIGHTING EMITTING Diode), a chip, a Diode, a resistor, and a connector housing.

The colors and the brightness of the first light emitting element 1 and the second light emitting element 2 can be changed according to the needs (for example, when the vehicle is opened, ignited, accelerated and respectively corresponding to different colors and brightness), so that the flowing change of the colors of the atmosphere lamp is realized.

It should be noted that, in this embodiment, the light emitted by the first light emitting element 1 and the second light emitting element 2 can be emitted onto the decorative board 4 by means of the light guiding element 3, so that the surface light emitting effect is achieved, and on the basis of the surface light emitting effect, no matter how the colors and the luminances of the first light emitting element 1 and the second light emitting element 2 change (i.e. whatever light control scheme is adopted), the flowing change of the color of the atmosphere lamp can be achieved (for example, when the left front door is opened, the color of the first light emitting element 1 changes to red, the luminance value changes to 10, the color of the second light emitting element 2 changes to green, and the luminance value changes to 10), so that the flowing water function of the atmosphere lamp can be achieved at low cost.

The principle that the atmosphere lamp realizes color and brightness change is as follows: the vehicle door opening signal, the CAN signals of ignition, turning, reversing and the like are transmitted to the host computer, the host computer converts the corresponding signals into LIN signals and transmits the LIN signals to the atmosphere lamp, and the atmosphere lamp executes corresponding functions according to the LIN signals, for example, the RGB values and the brightness definition values given in the analysis signals are used for carrying out color and brightness changes; the above principle belongs to the prior art and will not be described in detail here.
