<P>PROBLEM TO BE SOLVED: To secure desired luminance by using a plurality of chip LEDs. <P>SOLUTION: This electric lamp type LED luminaire 1 having an electrode base 2 has a heat transfer case 3 incorporated with a power circuit, and a light transmissive cover 4 surrounding a substrate structure 5 of a polyhedral structure constituted of a plurality of substrates 6 and 7 mounted with a plurality of low luminance chip LEDs 10. The light transmissive cover 4 is formed as an inside-outside double structure of an outside cover 4a and an inside cover 4b, and has a sealing space 4c between the outside cover 4a and the inside cover 4b, and proper gas is sealed in the sealing space 4c. Fluorescent paints 22 and 24 are also typically applied to the outside cover 4a and the inside cover 4b. <P>COPYRIGHT: (C)2010,JPO&INPIT |
