Description

Smart car lights

【Technical field】

The invention relates to an intelligent vehicle lamp, in particular to an intelligent vehicle lamp capable of automatically adjusting light color.

【Background technique】

At present, with the development of the automobile industry, the performance of automobiles is gradually improved, and the price is gradually reduced. More and more people start to use automobiles, and the development of automobile components cannot be ignored. For car buyers, safety, comfort, energy saving and diversification have always been important indicators for car purchases, and they are also the direction that car manufacturers are striving to develop. Especially the safety of the car is the primary consideration for the vast majority of buyers. However, there are still some safety hazards in most cars at present. For example, when driving in rainy or foggy weather, the concentration of water molecules in the air increases, which increases the absorption of some light. The glare of the headlights is caused by the diffraction or diffusion of light, whether it is day or night, it will make the driver's vision bad, seriously affect the driver's judgment and operation, and thus may cause many traffic accidents.

At the same time, cars often need to use various light colors when driving in different weather and road conditions or when they are used to perform special tasks such as ambulance and police. To change to the lights of the desired color at any time, only a plurality of different types of lights can be installed on the car to meet the needs of different situations. Multiple lights increase the energy consumption of the car, and also make the driver's way of controlling the car more complicated.

【Content of invention】

In view of this, it is necessary to provide an intelligent car light that can automatically adjust the color of the light.

An intelligent car light, which includes a light source, a control module and a sensing module, the light source can emit light of various colors; the control module controls the light source; the sensing module senses the external environment; wherein, the sensing The detection module is electrically connected to the control module, the control module is electrically connected to the light source, the sensing module transmits the information sensed from the outside to the control module, and the control module judges the color of the required lamp according to the received information, thereby controlling the light source.

Compared with the prior art, the intelligent car light can automatically adjust the color and light intensity of the car light according to different driving environments, and can also be used as a warning light, which realizes energy saving while eliminating potential safety hazards.

【Detailed ways】

Please refer to FIG. 1 , a preferred embodiment of the smart car light of the present invention includes a light source 10 , a control module (not shown), a power supply 40 and a sensing module 50 .

Please refer to FIG. 2 and FIG. 3 , the light source 10 includes a lampshade 12 , a plurality of illuminants 14 and a light-transmitting mirror 16 . The lampshade 12 is an open shell, which is a parabolic surface, used for accommodating a plurality of illuminants 14 and converging light. The plurality of illuminants 14 are light emitting diodes (Light Emitting Diode, hereinafter referred to as LED) light sources of a group of different colors, which are red, green and blue light emitting diodes in this embodiment; the plurality of illuminants 14 are installed At the focal point of the lampshade 12 , the light from the illuminant 14 is emitted from the open end of the lampshade 12 . The light-transmitting mirror 16 is installed on the open end of the lampshade 12, so that the open end of the lampshade 12 is closed; the light-transmitting mirror 16 is made of a transparent material, and cooperates with the lampshade 12 to form a closed cavity. There are tiny protrusions distributed on the mirror surface 18 opposite to the plurality of illuminants 14. The protrusions can be cylinders, cones, triangular bodies or cuboids. , due to the diffraction effect, the light emitted through the light-transmitting mirror 16 is uniformized, thereby expanding the range of light; at the same time, the light-transmitting mirror 16 can protect the plurality of illuminants 14 .

The control module includes a plurality of control units 20 and a signal processing unit 30 , and the control units 20 are connected with the signal processing unit 30 . The plurality of control units 20 can be current controllers, which are respectively connected to LED light sources of one color in the plurality of luminous bodies 14, and the control unit 20 controls the opening and closing of the LED light sources and controls the plurality of luminous bodies according to the intensity of the control current. 14 brightness. The power supply 40 provides the working voltage for the intelligent vehicle lamp.

The sensing module 50 is used for sensing the external environment, which includes a light intensity sensor and an environment sensor or one of them. The light intensity sensor can be an ordinary light detector for sensing the intensity of external light; the environment sensor can be a water drop sensor for sensing fog or rain in the external environment.

Wherein, the sensing module 50 is electrically connected with the signal processing unit 30 of the control module, and the sensing module 50 transmits the light intensity information or rain and fog information sensed from the outside to the signal processing unit 30, and the signal processing unit 30 transmits the external signal according to the received information. Process the results of environmental changes, judge the color of the illuminant 14 of the required car light, and connect the corresponding control unit 20, so as to connect the LED light sources of the required color among the plurality of illuminants 14 and control the brightness of the illuminant 14 .

When the sensing module 50 detects that the brightness of the external environment drops, it will turn on the lights through the control module; 14, to increase the penetrating ability of light in dense fog or rain; at the same time, if it is generally dark, turn on the car lights to a weaker brightness to save energy.

During the use of the plurality of illuminants 14, in addition to turning on LEDs of different colors, multiple colors can also be synthesized into another color, such as red light and green light with a certain intensity ratio can be synthesized into yellow light, etc. . In addition, the illuminant 14 can also be just a common white lamp.
