Title:
LIGHT IRRADIATION SYSTEM
Document Type and Number:
Japanese Patent JP2021121537
Kind Code:
A
Abstract:
To provide a light irradiation system capable of efficiently lighting up over a range from a far location to a near location.SOLUTION: A camera unit 42 is mounted at a main body case 2 of a car room photographing camera 1 of a drive recorder, and an infrared LED 39A with a half value angle ± 10 degrees and an infrared LED 39B with a half value angle ± 60 degrees with lower radiation intensity relatively than that of the infrared LED 39A are arranged near the camera unit 42B as auxiliary lighting. Then, the main body case 2 is installed inside a front wind shield of a vehicle by a hanging bracket 3. In the case that photographing is performed with the camera unit 42, in particular, when the photographing is carried out in dark at night or the like, the infrared LEDs 39A and 39B are applied as the auxiliary lighting to cause the infrared rays to be radiated to perform photographing. With this arrangement as above, a front seat side can be more clearly irradiated over a wide range and at the same time the rear seat can be clearly irradiated in spot.SELECTED DRAWING: Figure 3
