Problems solved by technology

However, due to the limited angle range of the ambient light collection angle of the existing light sensor, the front light sensing is weak, and it is impossible to accurately judge the driving environment of the vehicle, which is prone to misjudgment

Embodiment Construction

[0020] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0021] A light sensor of the present invention includes a front light assembly and an upper light assembly, the front light assembly includes a front light optical module and a front light sensor module, the front light optical module includes a front light lens 1, and the front light sensor module includes a front light receiving tube 2. After the light passes through the front optical lens 1, it is received by the front light receiving tube 2.

[0022] The upper optical assembly includes an upper optical module and an upper optical sensor module. The upper optical module includes an upper optical lens 3 . The upper optical sensor module includes an upper lig...

Abstract

The invention relates to a light sensor. An upper light lens collects outside light to an upper light sensor module to judge vehicle running ambient light. A front light lens collects front light to a front light sensor module to determine whether the vehicle lights are opened or closed. By combining ambient light and front light, judgment is more accurate. As the lower surface of the upper light lens is a wavy free-form surface composed of a plurality of approximate semi-cylindrical strip surfaces arranged side by side, more outside light can be detected, light entering an upper light receiving tube has a large incident angle and range, the upper light receiving tube can collect actual ambient light, misjudgment caused by non-local light is avoided, and the switch of the headlight can be adjusted before a vehicle goes into a light changing environment.

Description

technical field [0001] The invention relates to the technical field of vehicle control devices, in particular to a light sensor. Background technique [0002] At present, the turning on and off of vehicle lighting lamps is generally based on the driver's judgment. At dusk and dawn, or when a car enters or exits a tunnel or is parked underground, the external light will be dimmed or brightened. Due to the difference in the driver's visual ability or experience judgment, it is easy to cause the danger of large or small car accidents due to poor response to brightness. In addition, when the two vehicles meet head-on, improper or untimely switching of the far and near lights may also cause the other driver or his own eyes to be stimulated by the strong light of the far lights and cause a car accident. In addition, at dawn or in an environment from dark to bright, the driver may forget or be unable to know the on or off status of the car light from the instrument panel, so that...
