Abstract

When many LED lamps are provided on a printed wiring board to secure an amount of light, light can only be emitted from the side on which the lamps are provided, which limits the range in which light is emitted. To solve this problem, the present invention provides a plurality of chip type LED lamps 1 chained using conductive members 2 made of a flexible plate material.

Claims

1. A chained LED light source structure comprising a plurality of LED lamps or LED chips chained by flexible conductive members.

2. A chained LED light source structure comprising a plurality of LED lamps or LED chips mounted on flexible insulating members on which conductive sections are printed or fixed in such a way that said plurality of LED lamps or LED chips is chained through the conductive sections.
