<p>PURPOSE: A linear lighting system is provided to simultaneously realize improvement of uniformity in the emitted light distribution in the long direction of a linear light source and reduction of the cost. CONSTITUTION: A light emitting diode(21) is adopted as a red light source arranged on a light incidence face of a light guide member(11) which linearly diffuses light and is formed into a long rectangular parallelepiped, and an electric field light emitting element(33) is adopted as a blur light source fundamentally, and the light emitting diode and the electric field light emitting element(32) are properly combined and are adopted as a green light source. The electric field light emitting element is arranged in such positional relation that it mat reflect the light or the light emitting diode, and especially, a back face electrode(3) of the electric field effect element is widely formed so as to cover the upper face and side faces of the light guide member(11).</p> |
