Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a medical irradiation device which does not generate color irregularity at an edge of an irradiation area as a function of an LED module itself, has a function capable of adjusting color temperature, and improves visibility of the irradiation area for a doctor in the medical irradiation device using the LED module in a light source part.SOLUTION: A medical irradiation device 1 includes: an LED module 17 mounting plural LED chips thereon; and a reflection plate 2 including a reflection face 2a reflecting light of the LED module 17 to be condensed and changed into generally parallel light. The medical irradiation device irradiates an affected part with the LED light reflected by the reflection face 2a. Color arrangement of the LED chips arranged in an outer peripheral part of the LED module 17 is different from that of the LED chips arranged in a center part. On a surface of a part or all of the LED chips, a layer of a fluorescent material and/or diffusion material 41 is formed.SELECTED DRAWING: Figure 1
【課題】本発明は、光源部にLEDモジュールを用いた医科用照射器において、LEDモジュール自体の機能として照射エリアの端部に色むらを生じさせることが無く、また、色温度の調整も可能な機能を有し、照射エリアに対するドクターの視認性向上を図ることができる医科用照射器を提供する。【解決手段】本発明複数のLEDチップを搭載したLEDモジュール17と該LEDモジュール17の光を反射して集光および略平行光に変化させる反射面2aを有する反射板2とを有し、反射面2aで反射したLED光により患部を照射する医療用照射器1であって、LEDモジュール17の外周部に配置したLEDチップの色配列と、中央部に配置したLEDチップの色配列が異なり、前記LEDチップの一部または全部のLEDチップ表面に、蛍光体及び/又は拡散材41の層を形成した構成としたものである。【選択図】図1 |
