发明名称 LED lamp
摘要 An LED lamp A1 includes a plurality of LED modules 30 and a hollow diffusion pipe 20 accommodating the LED modules 30. Each LED module 30 includes an LED 31, and a resin package 32 covering the LED 31. The resin package 32 includes a light emission surface 35 opposed to the inner surface 21 of the diffusion pipe 20 and internally diffuses the light from the LED 31 to allow the light to be emitted from the light emission surface 35. The light emission surface 35 and the inner surface 21 of the diffusion pipe 20 are spaced from each other by a distance that is smaller than the distance between the light emission surface 35 and the LED 31. The arrangement reduces light distribution non-uniformity while increasing the amount of light emission.
