Title: Automatic lighting control apparatus
Inventor: SAKUGI MICHIHIKO
IPC: B60Q1/02
Filed: 1983-08-26
Abstract: PURPOSE:To obtain automatic regulation over operation sensitivity of a light receiving element by making the light incident on the light receiving emement through a control means for the quantity of transmitting light, which reduces the quantity of transmitting light as the quantity of the ultraviolet rays contained in the ambient light increases. CONSTITUTION:A filter 4 in use should be such that when it is irradiated by the ultraviolet rays, it reduces the degree of transmission of light by varying its color from a transparent state to darker color, according to the intensity of the ultraviolet rays. When a car goes into a tunnel at time T1 at twilight in which the output level comes between the first and second standard values, since the color of the filter 4 is kept dark because the filter 4 cannot follow an abrupt change in circumstances, the output level suddenly drops and the first standard value is surpassed at time T2, thereby lighting a head lamp 10. Thereafter, when the car comes out of the tunnel at time T4, since the filter 4 cannot vary its color instantaneously from light to dark, a large quantity of light comes incident one a photodiode 1 at a time, thereby making the output level exceed the second standard value. With this contrivance, even if the intensity of the ambient light becomes feeble at twilight, lighting or extinguishing of the head lamp 10 can securely be controlled by taking advantage of time-delay in color change of the filter 4.
