Description

This invention relates to lighting fixtures. Patent Document 1 discloses a lighting fixture comprising a fixture body mounted on a mounting surface, a socket and socket base positioned on the bottom surface of the fixture body, a light source unit fixed to the socket, and a fixture cover covering the light source unit. Japanese Patent Publication No. 2020-177845 Figure 1 is a partially cutaway side view of a lighting fixture according to an embodiment.Figure 2 is an exploded perspective view of a lighting fixture according to an embodiment.Figure 3 is a perspective view of the socket portion to which the lighting fixture according to the embodiment is attached.Figure 4 is a cross-sectional view of the lighting fixture and socket according to the embodiment.Figure 5 is a perspective view of the metal plate of the cap according to a modified example of the embodiment.Figure 6 is a perspective view showing an example of how to attach the cap according to a modified embodiment.Figure 7 is a perspective view showing another example of how the cap is attached according to a modified embodiment. The following describes in detail, with reference to the drawings, a lighting fixture according to an embodiment of the present invention. Note that the embodiments described below are all specific examples of the present invention. Therefore, the numerical values, shapes, materials, components, arrangement and connection configurations of components, steps, and the order of steps shown in the following embodiments are examples only and are not intended to limit the present invention. Accordingly, components in the following embodiments that are not described in an independent claim are described as optional components. Furthermore, each figure is a schematic diagram and not necessarily a strictly accurate representation. Therefore, for example, the scale may not necessarily match in each figure. Also, in each figure, substantially identical components are denoted by the same reference numerals, and redundant explanations are omitted or simplified. Furthermore, in this specification, terms indicating relationships between elements, such as parallel or perpendicular, terms indicating the shape of elements, such as circular or rectangular, and numerical ranges are not expressions that represent only strict meanings, but rather expressions that include substantially equivalent ranges, such as differences of a few percent. Furthermore, in this specification and the drawings, the x, y, and z axes represent the three axes of a three-dimensional Cartesian coordinate system. The z axis is perpendicular to the mounting surface (ceiling surface) of the lighting fixture. In each figure, the positive direction of the z axis is "upward," i.e., towards the ceiling relative to the lighting fixture, and the negative direction of the z axis is "downward," i.e., towards the floor. Furthermore, in this specification, ordinal numbers such as "first," "second," etc., unless otherwise specified, do not indicate the number or order of components, but are used to avoid confusion and distinguish similar components. (Embodiment) [Overall configuration of lighting fixtures] First, the overall configuration of the lighting fixture 1 according to the embodiment will be explained using Figure 1. Figure 1 is a partially cutaway side view of the lighting fixture 1 according to this embodiment. As shown in Figure 1, the lighting fixture 1 comprises a light source unit 10 and a shade 20. Figure 1 illustrates the positional relationship between the shade 20 and the light source unit 10 by partially cutting out the shade 20. The light source unit 10 is the main body of the lighting fixture 1. The light source unit 10 is, for example, a ceiling light fixed to the ceiling 2. Specifically, the light source unit 10 is detachably attached to a socket portion 30 mounted on the ceiling surface 3 of the ceiling 2 via a power supply terminal 121 (see Figure 2). The shade 20 is a component that covers the light source unit 10. The shade 20 alters the light distribution or color of the illumination light emitted by the light source unit 10. The shade 20 is also called a lampshade. The shade 20 is attached to the ceiling 2 via a mounting component different from the power supply terminal 121. The specific configuration of the lighting fixture 1 and the socket section 30 will be explained below, using Figures 2 to 4, with appropriate reference to Figure 1. Figure 2 is an exploded perspective view of the lighting fixture 1 according to this embodiment. Figure 3 is a perspective view of the socket portion 30 to which the lighting fixture 1 according to this embodiment is attached. Figure 4 is a cross-sectional view of the lighting fixture 1 and the socket portion 30 according to this embodiment. [Light source unit] As shown in Figure 2, the light source unit 10 comprises a unit body 110 and an adapter 120. As shown in Figures 2 and 4, the unit body 110 includes a fixture b
