More Information
Summary:A lens array (50) is provided with a lens plate (51) and a plurality of lenses (52). The lens plate (51) has lens regions (53) to which the lenses (52) are affixed, and non-lens regions (54) to which the lenses (52) are not affixed. A base plate to which LEDs are affixed has LED regions to which the LEDs are affixed, and non-LED regions to which the LEDs are not affixed. The lens plate (51) and the base plate (24) are fastened together with the lens regions (53) overlapping the LED regions and with the non-lens regions (54) overlapping the non-LED regions. As a result, it is possible to stably assemble the lens array to the base plate for the LEDs, and to achieve excellent illuminance distribution and size reduction.
