LIGHT IRRADIATION SYSTEM

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 【課題】遠方から近方にかけて効率的に照らし出すことができる光照射システムを提供すること。【解決手段】ドライブレコーダの車室内撮影用カメラ１の本体ケース２にカメラユニット４２を搭載し、カメラユニット４２Ｂ近傍に半値角±１０度の赤外線ＬＥＤ３９Ａと、赤外線ＬＥＤ３９Ａよりも相対的に放射強度の小さな半値角±６０度の赤外線ＬＥＤ３９Ｂとを補助照明として配置する。そして本体ケース２を吊り下げ用ブラケット３で車両のフロントガラスの内側に装着してカメラユニット４２で撮影する際に特に夜間等暗い場合に赤外線ＬＥＤ３９Ａ、３９Ｂを補助照明として赤外線を照射して撮影をする。これによって前部座席側を広い範囲で明瞭に照らし出すことができると同時に後部座席をスポット的に明瞭に照らし出すことができる。【選択図】図３
