Problems solved by technology

However, as we all know, LED light is cold light, which cannot simulate the different illuminance and color temperature of sunlight in a day.
Passengers in the carriage cannot perceive the change of daylight and the change of the human body due to the change of weather outside the carriage. Since the train travels for a long time, if you stay in a closed space without sunlight or in a place where the sun cannot reach It will make people feel depressed for a long time, and cannot bring passengers a better ride experience

Abstract

The invention discloses a light source driver, relates to the technical field of train interior lighting, is used for driving a lighting system of a train lamp to simulate sunlight irradiation on a train, and comprises an input end and an output end, the input end is connected with an external control signal end through a CAN communication line, and the output end is electrically connected with the lighting system. The light source driver adjusts the PWM duty ratio according to an external control signal received by the input end so as to drive the lighting system to simulate sunlight irradiation. The device can drive a train lamp to simulate sunlight and changes thereof in a train compartment.

Description

technical field [0001] The invention relates to the technical field of train interior lighting, in particular to a light source driver. Background technique [0002] In the prior art, the lighting fixtures in the train compartment can only realize the general lighting function. At present, based on the development of LED technology and the excellent energy-saving performance of LEDs, LED lamps are generally used for lighting in train compartments. However, as we all know, LED light is cold light, which cannot simulate the different illuminance and color temperature of sunlight in a day. Passengers in the carriage cannot perceive the change of daylight and the change of the human body due to the change of weather outside the carriage. Since the train travels for a long time, if you stay in a closed space without sunlight or in a place where the sun cannot reach It will make people depressed for a long time and cannot bring more excellent ride experience to passengers. Con...
