发光模块及车辆用灯具
摘要：
本发明涉及一种防止短路发生的发光模块。设有：陶瓷基板(2)，其形成为大致矩形，且外周面中的1个侧面形成为与散热体(16)的定位面(20a、20a)相抵的抵接面(2c)，厚度方向上的一个表面形成为配置半导体发光元件的元件配置面(2a)；规定的导电图案(5、5)，其在该陶瓷基板上形成；发光部(3A)，其具有半导体发光元件(3)；以及正负一对平面状电极部(6、6)，其经由在陶瓷基板上形成的导电图案与半导体发光元件连接，使该一对平面状电极部的至少一部分为在陶瓷基板的元件配置面露出的露出区域(6a、6a)，使该露出区域位于元件配置面的外周部中，与抵接面相连续的部分以外的部分上。
摘要（英）：

A ceramic board is formed in an almost rectangular shape and has one side surface of an outer peripheral surface formed as an abutting surface, which is caused to abut on positioning surfaces of a radiating member, and one surface in a vertical direction formed as a device disposing surface on which a semiconductor light emitting device is to be disposed. Predetermined conductive patterns are formed on the ceramic board. A light emitting portion has a semiconductor light emitting device. A pair of positive and negative planar electrode portions are formed on the ceramic board and connected to the semiconductor light emitting device through the conductive patterns. At least a part of the pair of planar electrode portions are set to be exposure regions exposed to the device disposing surface of the ceramic board and the exposure regions are positioned in portions other than a portion linked to the abutting surface in an outer peripheral portion of the device disposing surface.
