The invention provides a light-emitting device which is configured to emit emergent light, and the emergent light has brightness distribution. The light-emitting device comprises a light adjusting structure, wherein the emergent light is adjusted through the light adjusting structure. The emergent light defines a sub-light corresponding to an azimuth angle. The brightness sum of the sub-light corresponding to the polar angle of 115 degrees to 125 degrees is a first numerical value L1, the brightness sum of the sub-light corresponding to the polar angle of 95 degrees to 105 degrees is a second numerical value L2, the brightness sum of the sub-light corresponding to the polar angle of 75 degrees to 85 degrees is a third numerical value L3, and the brightness sum of the sub-light corresponding to the polar angle of 55 degrees to 65 degrees is a fourth numerical value L4. The first value L1, the second value L2, the third value L3 and the fourth value L4 meet the following relation: L3lt; l2; and 1.23 < = (L1 * L3)/(L2 * L4) < = 2.92.

    本发明提供了一种发光装置,其配置为能发射一出射光,且出射光具有一亮度分布。发光装置包括一光调整结构,其中出射光透过光调整结构而被调整。出射光对应于一方位角定义出一子光线。子光线对应极角115度到极角125度的亮度总和为一第一数值L1,子光线对应极角95度到极角105度的亮度总和为一第二数值L2,子光线对应极角75度到极角85度的亮度总和为一第三数值L3,子光线对应极角55度到极角65度的亮度总和为一第四数值L4,且第一数值L1、第二数值L2、第三数值L3和第四数值L4满足以下关系:L3
