Single-light type light dimmer

Abstract

The invention relates to the field of motor vehicle lighting control and discloses a single-light type light dimmer which comprises a capacitor, a photosensitive sensor, a triode and a relay which are all connected in a circuit. The photosensitive sensor is connected with the triode through a wire, the triode is connected with the relay through a wire, the normally closed end of the relay is connected with a high-beam light through a wire, and the normally open end of the relay is connected with a low-beam light through a wire. The single-light type light dimmer can be automatically switched from the high-beam light to the low-beam light when motor vehicles pass each other and switched back to the high-beam light when the motor vehicles do not pass each other. The light dimmer provides enough light for running vehicles under the condition that natural light is lacked even does not exist, such as at night and in tunnels.

Description

technical field [0001] The invention relates to the field of motor vehicle lighting control, in particular to a single-light dimmer. Background technique [0002] According to the data released by the World Health Organization, 1.2 million people die in traffic accidents every year in the world, with an average of one traffic accident every half minute, and the death toll of accidents mainly occurs in developing countries. There are 500,000 traffic accidents in China every year, and the death toll due to traffic accidents exceeds 100,000, accounting for about 16% of the world's total and ranking first in the world. In China, one person is killed by the wheel every 5 minutes, and one person is disabled due to a traffic accident every 1 minute. The economic losses caused by traffic accidents amount to tens of billions of yuan every year, and excessive driving of high beams is the culprit of traffic accidents. Although the density of driving at night is generally only 10-20% o...

Problems solved by technology

The economic losses caused by traffic accidents amount to tens of billions of yuan every year, and excessive driving of high beams is the culprit of traffic accidents. Although the density of driving at night is generally only 10-20% of that during the day, the traffic accidents of driving at night are increasing , especially when driving at night without natural light or meeting cars in a tunnel, if the headlights of the car are not adjusted from the high beam to the low beam in time, it will seriously affect the driving of the other vehicle and eventually lead to a car accident
