<P>PROBLEM TO BE SOLVED: To provide a compact lighting system having very high illuminance and uniform light distribution characteristics and being manufacturable comparatively at low cost. <P>SOLUTION: A lamp 10 for reading is provided with an electrical wiring board 15 on which a connector 15a for power supply is formed, a plurality of LED chips 11 mounted on the electrical wiring board 15 in a predetermined arrangement pattern, a deflection lens array 13 which is arranged among the LED chips 11 and a predetermined illumination region Z, while being close to these LED chips 11 and in which a plurality of deflection lenses 17 for leading light emitted from the LED chips 11 into the predetermined illumination region Z, while the light is in a state of being mutually overlapped are integrally formed, and a housing 14 storing these deflection lens array 13 and electrical wiring board 15. The light emitted from the LED chips 11 is collected, in a state of all of the light being superimposed in the common and single illuminating region Z via the deflection lenses 17. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
