<P>PROBLEM TO BE SOLVED: To provide an LED lighting apparatus capable of efficiently condensing a light in a linear region. <P>SOLUTION: The LED lighting apparatus has a plurality of linearly arranged LEDs 11 and a transparent column member 13 arranged on the fronts of the LEDs so that an axis runs parallel with lines tying a plurality of the LEDs 11. Light diffusion means may be fitted among the LEDs 11 and the column member. The light can be condensed efficiently in the linear region by the column member, and a bright uniform illumination is enabled. A structure is simplified and can be manufactured at a low cost, and is strengthened. The number of the LEDs can be suppressed than conventional devices, and the operating temperatures of the LEDs are lowered. Accordingly, the deterioration in a brightness due to a temperature rise can be prevented because a heat generation is also reduced by abolishing several pieces of factors, resulting stabilizing an operation. <P>COPYRIGHT: (C)2007,JPO&INPIT |
