[Problem] To provide a light-emitting diode lamp with which it is possible to obtain a broader light distribution and light emission intensity in the length direction of the lamp, and with which heat can be dissipated efficiently and which therefore has a longer operating life. [Means of overcoming the problem] A light-emitting diode lamp (20) is provided with a light-emitting diode unit (10) in which light-emitting diodes (11) are mounted on the side surfaces of a prismatic support member (13), and a cylindrical glass bulb (21) having a prescribed bulb diameter, inside which the abovementioned light-emitting diode unit (10) is arranged, and if the width w of one side surface of the above-mentioned support member (13) is fixed at a prescribed width w, the distance k from the center of one side surface of the abovementioned support member (13) to the inner surface of the bulb is fixed at a prescribed distance, and the cross- section through the abovementioned prismatic support member (13) is a regular n-sided polygon, then the abovementioned n is a value whereby the abovementioned light-emitting diode unit (10) can be arranged inside a cylindrical bulb having the abovementioned prescribed bulb diameter, and is a value which is determined based on the abovementioned prescribed bulb diameter, prescribed width and prescribed distance. |
