Abstract

A light bulb includes an elongated base board having a first end and a second end at opposed ends of a longitudinal axis of the base board, and an upper surface. A single line of light-emitting diodes is arranged parallel to the longitudinal axis of the base board and between the first end and the second end. A base is provided for receiving power. A translucent seal that includes a wavelength conversion material is provided, in which the seal covers the light-emitting diodes and covers the upper surface of the base board. A first power supply lead and a second power supply lead are provided for supplying power to the light-emitting diodes. A housing that houses the base board, the light-emitting diodes, and the power-supply leads, is provided in which the housing is attached to the base.
