Vehicle indoor lamp capable of achieving constant illuminance illumination and color temperature compensation

Abstract

The present invention discloses a vehicle indoor lamp capable of achieving constant illuminance illumination and color temperature compensation, belonging to the field of vehicle indoor lamp illumination. The vehicle indoor lamp comprises a light intensity detection module, a switch, a dimming and color regulation module and a temperature detection module, the light intensity detection module collects light intensity in the vehicle and sends light intensity data to the dimming and color regulation module in a wireless transmission mode; the temperature detection module detects the temperaturein the vehicle and sends the temperature data to the dimming and color regulation module in a wireless transmission mode; and the dimming and color regulation module receives the light intensity dataand the temperature data sent by the light intensity detection module and the temperature detection module. The vehicle indoor lamp employs the ZigBee wireless communication technology and the sensortechnology to perform automatic regulation of the light illuminance and the color temperature in the vehicle according to the change of the external environment so as to achieve constant illuminance illumination of the light illuminance without change with the external environment and control of color temperature compensation of the color temperature with the change of the temperature in the vehicle, avoid complex wiring, improve the illumination quality and reduce the energy consumption.

Description

technical field [0001] The invention belongs to the lighting field of automobile interior lamps, relates to wireless communication technology and power electronics technology, in particular to an automobile interior lamp capable of realizing constant illuminance illumination and color temperature compensation. Background technique [0002] At present, most conventional car interior lights use a single color temperature light source, and the brightness is also fixed. A few can adjust the brightness value, but it is also manually adjusted by the passenger, and the external environment changes all the time. This method is not only inconvenient, but also frequently touches the switch. Handling is also one of the reasons for the destruction of indoor lights. [0003] Color temperature is an important indicator of lighting quality. Changes in color temperature can create different atmospheres. Studies have shown that color temperature of light sources plays a certain role in body ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the problem that the light intensity and color temperature of the current automobile interior lamps cannot be automatically adjusted, the present invention provides an automobile interior lamp capable of realizing constant illuminance lighting and color temperature compensation. RGB LED is used as the light source of the automobile interior light, which not only realizes brightness adjustment, but also It can realize color temperature control, adopts sensor technology and ZigBee wireless communication technology, automatically adjusts the illuminance and color temperature in the car according to the change of the external environment, and realizes the constant illuminance lighting in the car that does not change with the external environment and the color temperature that the color temperature changes with temperature Compensation control avoids complex wiring, improves lighting quality and reduces energy consumption
