APPARATUS FOR SENSING OF SOLAR

摘要

The present invention is to improve the sensitivity of the light by adjusting the intensity of incident light irradiated on an optical sensor in an initial state and then setting a balance; thereby sensing the correct position of sunlight early in the morning or at the end of a sunset when intensity of the light is very weak, as well as the summer season when the intensity of the light is very strong. The apparatus includes: a partition protruding from the top surface of a body; first and second detection units provided opposite to each other based on the partition; a first light inlet port formed adjacent to the partition, where sunlight comes in from an upper portion of the body; a first light guide path to guide the sunlight entering from the light inlet port to an optical sensor installed in a darkroom through a light outlet port; a second light inlet port to receive the sunlight from the side of the body; a second light guide path to guide the sunlight entering from the second light inlet port to the optical sensor installed in the darkroom through the light outlet port; a first light intensity adjusting unit provided on a line of the first light guide path and a second light intensity adjusting unit provided on a line of the second light guide path; and first and second light intensity adjusting members each fastened to the first and second light intensity adjusting units to adjust the intensity of the incident light for the sunlight entering from the first and second light inlet ports.
