摘要 | To improve an angular color difference and emit uniform illumination light. According to an embodiment, a light-emitting device in an embodiment includes a light-emitting module (15). The light-emitting module (15) includes a substrate (21), a plurality of light-emitting elements (45) made of semiconductor, and a plurality of sealing members (54). The light-emitting elements (45) are disposed on the substrate (21). The sealing members (54) contain, as a main component, translucent resin mixed with a phosphor. The sealing members (54) are heaped up from the bottom surfaces thereof bonded on the substrate (21) and are each formed to bury a singularity or a plurality of the light-emitting elements (45). A ratio (H/D) of a diameter D of the bottom surfaces to height H of the heaps of the sealing members (54) is set to 0.22 to 0. |
其他摘要 | 改善角度色差并发出均匀的照明光。根据实施例,实施例中的发光装置包括发光模块(15)。发光模块(15)包括基板(21),由半导体制成的多个发光元件(45)和多个密封构件(54)。发光元件(45)设置在基板(21)上。密封构件(54)包含与磷光体混合的半透明树脂作为主要成分。密封构件(54)从其粘合在基板(21)上的底表面堆积起来,并且每个密封构件形成为掩埋单个或多个发光元件(45)。底面的直径D与密封构件(54)的堆的高度H的比(H / D)设定为0.22至0。 |
