PROBLEM TO BE SOLVED: To provide an LED light source device capable of balancing heat radiation and perfect illumination.SOLUTION: A light emission diode (LED) light source device has a light source holder including a power module, an LED module, and a shield. The LED module provided on the light source holder is electrically connected to the power module. The shield provided on the light source holder covers the LED module. The material of the shield is solid. The shield has an upper part, a side part, a housing space, and an inside rough surface and an outside side face which face each other. The composition constituting the shield contains light diffusing powder. The side part is connected to the light source holder. The upper part is larger in thickness than the side part. The thickness of the shield substantially and gradually increases from the side part to the upper part. The LED module is located in the housing space, and the inside rough surface faces the housing space. |
