发明名称 Vehicle accessory having a rear light receiving sensor for measuring illumination intensity inside the vehicle
摘要 The present invention provides a vehicle accessory which reliably blocks the sunlight without any mechanical operation. The vehicle accessory includes: a light controlling sheet which is attached to the windshield of a vehicle, and of which light transmittance changes according to a value of voltage; and a rear view mirror which insures a rear view of the vehicle. The rear view mirror has a front light receiving sensor which measures illumination intensity of the sunlight which enters from the front of the vehicle, a rear light receiving sensor which measures illumination intensity inside the vehicle, and a circuit board which controls voltage to be applied to the light controlling sheet. When a combination of the illumination intensity of the sunlight received by the front light receiving sensor and the illumination intensity inside the vehicle received by the rear light receiving sensor is a combination stored in storage unit in advance, the circuit board applies voltage to the light controlling sheet.
