PROBLEM TO BE SOLVED: To provide an LED bulb capable of illuminating a wider region more properly.SOLUTION: An LED bulb 101 includes a light-emitting part 200, a pedestal 300, a power source part 500, a heat radiation member 400, a base 550 and a globe 600 for swelling to an X direction X1 side, for surrounding the light-emitting part 200 and for transmitting the light from the light-emitting part 200 while diffusing it. In a light amount from the light-emitting part 200, in the case where a central axis extending in the X direction is made to be 0°, a region of equal to or greater than 50% of the maximum light amount is within ±60°, and a light amount from the globe 600, in the case where the central axis is made to be 0°, becomes equal to or greater than 50% in a region of equal to or greater than ±125°.SELECTED DRAWING: Figure 2 |
