Problems solved by technology

However, there are disadvantages such as difficulty in accommodating parts in the socket part, and the parts to be accommodated are limited.
In addition, there are disadvantages such as increasing the size of the lamp holder in order to secure a storage space in the lamp holder, making it difficult to miniaturize the bulb-shaped lamp and increasing the cost of the bulb-shaped lamp.

Abstract

The invention relates to a bulb-shaped lamp and a lighting fixture, and the bulb-shaped lamp (1) comprises: a lighting module (2) which comprises a semiconductor lighting element (9); a metal device body (3) which comprises an installation part (14) formed at one side (3a) and a hole (17) formed to be approximately truncated-cone-shaped, wherein the lighting module (2) is installed on the installation part (14); an electric insulating resin shell (4) which is formed to be like a approximately truncated-cone-shaped cylinder, wherein the movement towards the installation part (14) is limited by the lighting module (2); an embedded recess (18) and an embedded projection (25) which are respectively formed at the inner wall side (17a) of the hole (17) of the device body (3) and the peripheral side (4c) of the resin shell (4), and are embedded together to limit the mutual rotation; a lighting circuit (5) which is contained inside the resin shell (4); and a lamp orifice (6) which is electrically connected to the lighting circuit (5).

Description

technical field [0001] The present invention relates to a bulb shaped lamp using a semiconductor light emitting element as a light source and a lighting fixture equipped with the bulb shaped lamp. Background technique [0002] Conventionally, in light bulb-shaped lamps using light-emitting diodes as semiconductor light-emitting elements, a light-emitting portion using a light-emitting diode (light emitting diode, LED) chip and a light-emitting portion covering the light-emitting diode (LED) chip are mounted on one end side of a metal holder (holder). The lampshade of the light emitting part has a socket attached to the other end side of the socket via an insulating member, and a lighting circuit is housed inside the insulating member (for example, refer to Patent Document 1). [0003] In the bulb-shaped lamp of the above-mentioned background art, the insulating member is made of synthetic resin such as polybutylene terephthalate (polybutylene terephthalate, PBT) resin, is fo...
