Abstract:
An LED lamp A1 includes a plurality of LED modules 1 and a substrate 2 on which the LED modules 1 are mounted in a row. A light guide 3 covering the LED modules 1 is provided on the substrate 2. The light guide 3 is held in close contact with each of the LED modules. With this arrangement, a proper amount of light is obtained with the use of a smaller number of LED modules 1 or with less power consumption.
