Abstract

The utility model provides an atmosphere lamp and vehicle, include: a light source, a singlechip and a LIN transceiver; the light source and the LIN transceiver are respectively and electrically connected with the singlechip. The utility model discloses a LIN transceiver communicates, can utilize current vehicle bus setting, also can help reducing development cost and shorten development cycle, light in weight. Each light source can be connected to the LIN network without additional wiring. Therefore, the overall system cost can be kept at a minimum level, and the total weight of the automobile cannot be increased, so that the increase of fuel consumption is avoided, and the designer can further improve the in-automobile experience by utilizing the packaging advantages of the LED.

Description

Atmosphere lamp and vehicle

Technical Field

The utility model relates to an electronic circuit field specifically relates to a RGB three-colour atmosphere lamp and vehicle.

Background

With the increasing use of various indoor ambient lighting mechanisms, more and more vehicles are beginning to use in-vehicle ambient lighting (mood lights). Patent publication No. CN107042789B discloses an in-vehicle lighting device that can simplify the light emission control of a light source as much as possible, can reduce the number of components and the cost due to the simplification of the control, and can obtain a high decorative effect. An interior lighting device for illuminating the interior of a vehicle, comprising: a plurality of light source units having light sources emitting light in three primary colors; and a control connector for controlling the on/off and brightness of predetermined two colors of all the light source units in the same manner, and for individually controlling the on/off and brightness of one color other than the predetermined two colors of each light source unit. Through different mixed color coordination, illumination of different colors can be realized.

However, the current interior atmosphere lamps need to be controlled through the CAN bus, which is costly and CAN significantly increase the overall weight of the vehicle, thereby increasing fuel consumption.

SUMMERY OF THE UTILITY MODEL

To the defect among the prior art, the utility model aims at providing an atmosphere lamp and vehicle.

According to the utility model provides a pair of atmosphere lamp, include: the device comprises a light source, a singlechip, a light guide strip and an LIN transceiver;

the light source and the LIN transceiver are respectively and electrically connected with the single chip microcomputer, the LIN transceiver is connected with an LIN bus, and each atmosphere lamp is used as a communication node on the LIN bus;

the light guide strip is connected with the light source.

Preferably, the light source comprises a single color LED or an RGB LED.

Preferably, the light guide strip is a flexible light guide strip, and the flexible light guide strip is connected with the light source.

Preferably, the light guide strip comprises a plurality of glass optical fibers and a light-transmitting cladding wrapped outside the plurality of glass optical fibers.

Preferably, a triangular reflecting sheet is arranged on the inner side of the light-transmitting cladding layer.

According to the utility model provides a vehicle, including foretell atmosphere lamp.

Preferably, the LIN transceiver is connected to a BCM module or an ALM module of the vehicle.

Compared with the prior art, the utility model discloses following beneficial effect has:

the use of a LIN transceiver for communication may utilize existing vehicle bus arrangements, may also help to reduce development costs and shorten development cycles, and is lightweight. Each light source can be connected to the LIN network without additional wiring. Therefore, the overall system cost can be kept at a minimum level, and the total weight of the automobile cannot be increased, so that the increase of fuel consumption is avoided, and the designer can further improve the in-automobile experience by utilizing the packaging advantages of the LED.

Drawings

Other features, objects and advantages of the invention will become more apparent upon reading of the detailed description of non-limiting embodiments with reference to the following drawings:

fig. 1 is a schematic structural view of the present invention;

FIG. 2 is a circuit diagram of the present invention;

FIG. 3 is a cross-sectional view of a light guide bar.

Detailed Description

The present invention will be described in detail with reference to the following embodiments. The following examples will assist those skilled in the art in further understanding the present invention, but are not intended to limit the invention in any way. It should be noted that various changes and modifications can be made by one skilled in the art without departing from the spirit of the invention. These all belong to the protection scope of the present invention.

As shown in fig. 1 and fig. 2, the utility model provides an atmosphere lamp, include: the device comprises a light source, a singlechip, a light guide strip and an LIN transceiver; the light source and the LIN transceiver are respectively and electrically connected with the single chip microcomputer, the LIN transceiver is connected with the LIN bus, and each atmosphere lamp is used as a communication node on the LIN bus; the light guide strip is connected with the light source.

The light source may comprise a single color LED or an RGB LED.

In this embodiment, the light guide strip is a flexible light guide strip, and the flexible light guide strip is connected with the light source. The light guide strip comprises a plurality of glass optical fibers and a light-transmitting cladding wrapped on the outer sides of the glass optical fibers. Because when setting up the atmosphere lamp in the car, need longer leaded light strip, and need arrange the leaded light strip is crooked, agrees to the uneven condition of giving out light very much to appear. As shown in fig. 3, in the present embodiment, a triangular reflective sheet 2 is disposed inside a light-transmitting envelope 1, so that the long light guide strip can be kept in a uniform light-emitting state in a bent state.

The above atmosphere lamp can be applied in a vehicle, and the LIN transceiver is connected with a BCM module or an ALM module of the vehicle.

The utility model discloses a on the basis, further use control algorithm to realize the mixed light to RGB LED colour, differentiation compensation between temperature compensation and the LED.
