灯泡形灯及照明器具

Bulb-type lamp and luminaire

Abstract

本发明提供一种灯泡形灯及照明器具,利用简单的构成使配光不均不易产生,并且能够宽配光化。球形灯罩(11)的细颈部(17)将一端(24)设定为最小径,将另一端(25)设定为最大径,自一端(24)侧向另一端(25)侧形成为扩径状。球形灯罩(11)的细颈部(17)在剖视时比将一端(24)的外缘与另一端(25)的外缘连结而成的虚拟直线更向内凹陷。光源部(12)包含半导体发光元件(31),并且以发光部(36)处于球形灯罩(11)的细颈部(17)的两端间的方式收纳于球形灯罩(11)。灯头(13)位于球形灯罩(11)的一端侧。
The invention provides a bulb-type lamp and a luminaire, simple formation is employed to prevent ununiform light distribution, and wide light distribution is realized. According to one embodiment, in a constricted part of a globe, one end is set to a minimum diameter, the other end is set to a maximum diameter, and a diameter thereof increases from the one end side to the other end side. The constricted part of the globe is concaved into the inside of an imaginary straight line connecting an outer edge of the one end and an outer edge of the other end when viewed in section. A light source part includes a semiconductor light-emitting element and is contained in the globe so that a light-emitting part is positioned between both the ends of the constricted part of the globe. A cap is positioned on one end side of the globe.
