Embodiment approach 1

[0082] Below, refer to Figure 1 to Figure 15 The LED unit 10 of Embodiment 1 is demonstrated. use Figure 16 to Figure 23 The lighting fixture 30 provided with the LED unit 10 of Embodiment 1 is demonstrated. In the drawings, the same reference numerals are assigned to the same components, and overlapping descriptions are omitted. However, the sizes and positional relationships of components shown in the drawings may be exaggerated for clarity of description. In the following description, each element constituting the embodiment may be constituted by a single component, and a single component may serve as a plurality of elements, or conversely, the function of one component may be shared by multiple components. accomplish.

[0083] The LED unit 10 of Embodiment 1 includes a base 1 , a light emitting device 3 , a holder 2 , and a cover member 9 . The base 1 has a plate-like outer shape. The light emitting device 3 uses an unillustrated LED chip as a light source. The li...

Embodiment approach 2

[0158] Below, refer to Figure 24 to Figure 48 The LED unit 10 of Embodiment 2 is demonstrated. use Figure 49 to Figure 52 The lighting fixture 30 provided with the LED unit 10 of Embodiment 2 is demonstrated. Figure 24 express Figure 29 AA section.

[0159] The LED unit 10 of Embodiment 2 is, for example, Figure 24 to Figure 26 As shown, a base 1 , a light emitting device 3 , an electric wire 4 , a holder 2 and a cover member 9 are provided. The base 1 has a plate-like outer shape. The light emitting device 3 is disposed on the first surface 1aa side of the base 1 . The light emitting device 3 has a light emitting unit 3 a that uses an unillustrated LED chip as a light source. The wire 4 is electrically connected to the light emitting device 3 so as to be able to supply power to the light emitting device 3 . The holder 2 fixes the light emitting device 3 on the base 1 . The cover member 9 has translucency and is disposed on the light emitting surface side of the ...

Embodiment approach 3

[0200] Figure 53 In the LED unit 10 of Embodiment 3 shown, the Figure 24 The shown LED unit 10 is mainly different from the cover member 9 in terms of shape modification and provision of the inner cover portion 8 . The same reference numerals are assigned to the same configurations as those in Embodiment 2, and description thereof will be omitted.

[0201] The LED unit 10 of Embodiment 3 is, for example, Figure 53 and Figure 54 As shown, an inner cover portion 8 is provided between the retainer 2 and the cover member 9 . The inner cover part 8 has an annular shape surrounding the light emitting part 3a when viewed from the light emitting surface side of the light emitting device 3, and has a second reflection surface 8ga that reflects light from the light emitting part 3a. An end portion 8 e of the inner periphery of the inner cover portion 8 is in close contact with the base portion 2 m of the holder 2 . The holder 2 has a positioning portion 2h that contacts the inn...

Abstract

The invention provides a LED unit and a lighting tool using same; the LED unit (10) has a plate pedestal (1), a lighting device (3) using a LED chip as a light source and arranged on a first surface (1aa) of the pedestal (1), a holder (2) fixing the lighting device (3) on the pedestal (1), and a transparent shield (9) arranged on the lighting surface of the lighting device (3) and on the pedestal (1).

Description

technical field [0001] The present invention relates to an LED unit and a lighting fixture using the LED unit. Background technique [0002] Conventionally, lighting fixtures using LED units have been proposed (see Japanese Patent Laid-Open No. 2012-182190 and Japanese Patent Laid-Open No. 2012-182192). Hereinafter, JP-A-2012-182192 is referred to as Document 1. [0003] The LED unit 110 of Document 1 such as Figure 55 As shown, a base 101 , a light emitting device 103 disposed on one surface side of the base 101 , and a cover 120 for transmitting light emitted from the light emitting device 103 are provided. The LED unit 110 includes a holder 102 that sandwiches the light emitting device 103 between the base 101 and an inner cover 140 that covers the holder 102 . The LED unit 110 includes a cover pressing member 121 sandwiching a flange portion 120 b of the cover 120 between the base 101 and an electric wire 104 for feeding power to the light emitting device 103 . In th...
