摘要: An illuminating device includes an LED element, and a reflecting surface arranged in front of the LED. The reflecting surface includes a second reflecting surface formed in a substantially conical face shape with an apex at an intersection between an optical axis of the LED and the mirror reflecting surface and a conical side wall bulged inward, and a first reflecting surface formed as a concave reflecting surface recessed forward and having a first focal point disposed at or near the light emitting element and a second focal point disposed on the optical axis between the first focal point and the intersection. A housing including a plurality of reflective surfaces might also be included, with the illumination device positioned within.

摘要: An illuminating device can include an LED element and possess the same light distribution characteristics as those of a common bulb having a coiled filament as a light emission source, and accordingly, can be used in place of such a common bulb. The illuminating device can include the LED and a mirror reflecting surface in front of the LED. The mirror reflecting surface can include a second reflecting surface formed in a substantially conical face shape with an apex at an intersection between an optical axis of the LED and the mirror reflecting surface and a conical side wall bulged inward, and a first reflecting surface formed as a concave reflecting surface recessed forward and having a first focal point disposed at or near the light emitting element and a second focal point disposed on the optical axis between the first focal point and the intersection.
