<p>PROBLEM TO BE SOLVED: To solve the problem that a road lamp using an LED as a light source irradiates useless light in a road width direction and fails to obtain a sufficient illuminance in spite of the use of an LED with a lens.SOLUTION: A plurality of lens built-in chip-like LEDs, each having a lens on both sides and an upper part of the LED, are arranged on a straight line in a direction in which the lenses are respectively attached to both sides. Multiple LED blocks disposed on the straight lines, respectively, are arranged in parallel. Light reflecting plates each having an angle of 90° or more with respect to the lens built-in chip-like LEDs are attached between the LED blocks disposed on the straight lines, respectively.</p> |
