Abstract

Provided is an illumination device in which the assembly operation can be simplified. An illumination device (100) comprises: an LED module (60); a heat-sink (30) which radiates heat from the LED module (60); a cover (50) which covers the LED module (60); a cap (10); and an insulating member (20) between the cap (10) and the heat-sink (30). The illumination device (100) comprises a light-source holding body (40) which has a latch part (44) that latches to the heat-sink (30) in order to hold the LED module (60) in the heat-sink (30). The cover (50) comprises a projection part (51) which engages with and latches to the light-source holding body (40) or the heat-sink (30). The insulating member (20) has an insertion part (21) which latches to the heat-sink (30) at one end side, and has a connection part (24) which screws into the cap (10) at the other end side.

Description

technical field [0001] The invention relates to a lighting device with a light source, in particular to a lighting device in the form of a light bulb. Background technique [0002] In recent years, with the increase in brightness of light-emitting diodes (LEDs), LEDs as light sources have gradually been used in lighting devices instead of light sources such as incandescent lamps and fluorescent lamps. The LEDs have characteristics such as low power consumption and long life. [0003] A lighting device using a light-emitting element such as an LED as a light source includes a substrate on which the LED is mounted, a heat sink for dissipating heat emitted by the LED, and the like. For example, a lighting device is disclosed, in which a power supply board on which a light-emitting element is fixed is fixed with screws on an aluminum heat dissipation member (radiator), and an upper box body and a lower box body ( Refer to Patent Document 1). [0004] Patent Document 1: Japanes...
