[0030] figure 1 It is a perspective view seen from below which shows an example of the LED lighting fixture of this embodiment. The LED lighting fixture 1000 includes the LED light source unit 100 and the main body unit 200 of the present invention as main components. The LED light source unit 100 is characterized in that the pair of extending regions 33 of the cover member 30 have protrusions 35 to form a gap between the pair of opening edge portions L of the main body unit 200 and the facing extending regions 33 of the cover member 30 . Hereinafter, the structure of the LED light source unit 100 will be described first, and then the structure of the main body unit 200 will be described. In addition, the LED light source unit described below is also an illustration of the LED light source unit of the present invention.

Abstract

An object of the present invention is to provide an LED light source unit, a main body unit, and an LED lighting fixture capable of suppressing noise generated when lighting is turned on or turned off, and reducing heat generated during lighting. The LED light source unit (1000) of the present invention is characterized in that the two edge portions passing through the cover member (30) in the short side direction (X) are closer than the two openings in the short side direction of the concave portion of the main body unit. A pair of extension regions (33) formed by extending outwards, in use, between at least one of the two opening edge portions and the corresponding extension region (33) of the cover member (30), at least partly has Clearance (50).

Description

technical field [0001] The invention relates to an LED light source unit, a main body unit and an LED lighting appliance. Background technique [0002] As a ceiling-mounted lighting fixture, there is generally known a lighting fixture including an elongated fixture main body having a recessed portion substantially at the center, and a light source unit attached to the recessed portion of the fixture main body. The light source unit includes, for example, a light source and a mounting portion. The light source of the light source unit is accommodated inside the equipment main body by attaching the mounting portion of the light source unit to the concave portion of the equipment main body. As said ceiling direct mounting type lighting fixture, the LED (Light Emitting Diode) lighting fixture described in patent document 1 is mentioned, for example. [0003] In the LED lighting fixture described in Patent Document 1, the light source unit further includes a cover member. The ...
