    • Disclosed is a light emitting diode (LED) street lamp using an LED as a light source and capable of minimizing a luminance deviation within an illuminated area while increasing the luminance of the entire illuminated area. The LED street lamp includes a case provided at a front end of a lamp post; a board provided inside the case and having a plurality of LEDs spaced apart from each other; and heat dissipation units closely adhered to the board and dissipating heat generated when the LEDs emit light, wherein the plurality of LEDs have different luminance levels from each other, the luminance levels gradually increase from the center of the board to the edge of the board, and diffusing members diffusing the light generated from the plurality of LEDs are provided on board portions corresponding to areas between each of the plurality of LEDs.
    • 公开了一种使用LED作为光源的发光二极管(LED)路灯,并且能够在增加整个照明区域的亮度的同时使照明区域内的亮度偏差最小化。 LED路灯包括设置在灯柱前端的壳体; 设置在壳体内并具有彼此间隔开的多个LED的板; 并且散热单元紧密地粘附到板上并散发当LED发光时产生的热量,其中多个LED彼此具有不同的亮度级别,亮度级别从板的中心逐渐增加到板的边缘, 并且扩散从多个LED产生的光的漫射构件设置在对应于多个LED中的每一个之间的区域的板部分上。
