发光装置
摘要：
公开了一种发光装置(1)，包括：LED芯片(10)；安装基板(20)，其用于安装LED芯片；封装部件(50)，其由封装树脂材料制成，用以封装LED芯片；以及透镜(60)，其由透明树脂材料制成。透镜(60)在其底部被提供有凹部(40)；并且，通过将封装部件(50)安置在凹部(40)内，将透镜(60)固定至安装基板(20)。由于封装部件(50)被限定在透明树脂材料的透镜的凹部内，从而使得封装部件和其周围之间线性膨胀系数的差异最小化，进而抑制了低温下封装部件中的空洞产生。
摘要（英）：

Disclosed is a light-emitting device (1) comprising an LED chip (10), a mounting board (20) on which the LED chip is mounted, a sealing portion (50) which is composed of a sealing resin material for sealing the LED chip, and a lens (60) made of a transparent resin material. The lens (60) has a recessed portion (40) in the bottom and is fixed to the mounting board (20) in such a manner that the sealing portion (50) is housed in the recessed portion (40). Since the sealing portion is surrounded by the transparent resin lens, the linear expansion coefficient difference between the sealing portion and the surrounding area thereof can be reduced in this light-emitting device. Consequently, there can be suppressed generation of voids in the sealing portion at low temperatures.
