Abstract
Problem. To provide a light-emitting diode lamp (20) 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 problems. 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 or cylindrical support member (13), and a housing (24) having a glass cover which envelops the light emitting surface of the abovementioned light-emitting diode unit (10) and which is arranged inside the light-emitting diode unit (10), and in which the height of the abovementioned light-emitting diode unit (10) in the axial direction of the support member (13) is a length which is between 1.5 times and 3.5 times the diameter of the circumcircle of the abovementioned support member (13).
