Embodiment Construction

[0011] The present invention will be further described in detail through specific embodiments below.

[0012] Practical design of auto headlight automatic dimmer, circuit figure 2 Among them, T1 and its bias circuit are composed of R1, R2, R3, R7, R11 and T6. Among them, R1 is a photosensitive resistor whose resistance value decreases rapidly with the increase of light. The upper potential Va is set by R7, while the lower potential Vb depends on photoresistors R1, R2 and R3 and T6 grounded by T6, and the resistance at the lower end will drop rapidly. Therefore, if the resistance of R7, R2 and R3 is properly adjusted, the photosensitive characteristics will be adjusted. When the high beam is on, the base of T6 is connected to the positive pole of the power supply through R15, so T6 is turned on. When the other car approaches and the illuminance increases, the resistance of R1 decreases, T1 is turned on, and T2 is also turned on, so that T3 is turned off. T4 is turned on, and ...

Abstract

The invention relates to driving safety of an automobile at night and development and comprehensive utilization of maintenance projects. According to the principles of photoelectric engineering science, a photometric system circuit and a light-sensing transducer circuit, a certain resistance is generated when lamp light incomes on an illuminated face of a photoresistor at night, so that the headlamp on full beam is taken as an initial state at the constant pressure and current and other well-adjusted circuit parameters, and a dipped headlamp is adjusted to when a car on the opposite side comes. The sensitivity of the light-sensing transducer regulates the bias voltage, and the required potential for conduction is just increased, so that change time for passing light and distant light is provided to automatically change the headlamp on full beam and the dipped headlamp, so as to guarantee safety driving at night.

Description

Technical field: [0001] The invention relates to the comprehensive development and utilization of automobile night driving safety and maintenance engineering, which belongs to the automobile optical, mechanical and electrical engineering. Background technique: [0002] In the existing automobile headlights, the far and near beam conversion switch is mostly completed by a toggle switch. The current first enters the toggle switch and then enters the fuse to the far and near beam headlights. When the vehicle is driving at night, one side of the light does not change or there is Excessively bright lights on one side will cause dizziness and affect safe driving. As cars enter thousands of households, novices and veterans go on the road together, and there are indeed certain safety risks. Invention content: [0003] The purpose of the present invention is to reduce unnecessary losses. From the purpose of being economical, practical and durable, a new type of automatic light dim...
