Example Embodiment

[0040] (Example 1)

[0041] [structure]

[0042] First, with respect to the overall structure of the light bulb-shaped lamp according to Example 1, using figure 1 as well as figure 2 Be explained.

[0043] figure 1 It is a cutaway perspective view of a part of the LED lamp 1 according to the present embodiment. figure 2 It is a cross-sectional view of the LED lamp 1 according to this embodiment. Moreover, in figure 1 Among them, in order to show the LED module 10 inside the dome cover 50 , a part of the dome cover 50 is cut and shown.

[0044] and, in figure 1 as well as figure 2 In the figure, the lamp axis (central axis) J of the lightbulb-shaped lamp 1 is shown along the dashed-dotted line drawn in the vertical direction of the drawing. In this embodiment, the lamp axis J coincides with the axis of the dome cover 50 (the dome cover axis). In addition, the lamp axis J is an axis that becomes the center of rotation when the lightbulb-shaped lamp 1 is attached to ...

Example Embodiment

[0124] (Variation 1)

[0125] Next, for Modification 1 of Embodiment 1, use Figure 5 as well as Image 6 Be explained. Figure 5 It is a cutaway perspective view of a part of the lightbulb-shaped lamp 101 which concerns on this modification. Image 6 It is a cross-sectional view showing the LED module 10 , the information acquisition module 40 , and the reflector 70 of the light bulb-shaped lamp 101 according to this modification.

[0126] like Figure 5 as well as Image 6 As shown, the lightbulb-shaped lamp 101 is different from the lightbulb-shaped lamp 1 according to the first embodiment in that the reflector 70 is newly provided. Hereinafter, the differences from Example 1 will be mainly described, and the description of the common points will be omitted.

[0127] The reflection plate 70 is arranged around the information acquisition module 40 . In the present modification, the reflector 70 is a cylindrical body whose axis is the penetration direction of the throu...

Example Embodiment

[0137] (Variation 2)

[0138] Next, for Modification 2 of Embodiment 1, use Figure 7 Be explained. Figure 7 It is a sectional view of the lightbulb-shaped lamp 201 which concerns on this modification.

[0139] like Figure 7 As shown, the lightbulb-shaped lamp 201 is different from the lightbulb-shaped lamp 1 according to the first embodiment in that the resin cover 80 is newly provided. Hereinafter, the differences from Example 1 will be mainly described, and the description of the common points will be omitted.

[0140] like Figure 7 As shown, the resin cover 80 covers the information acquisition module 40 . Specifically, the resin cover 80 is a case in which the information acquisition module 40 is accommodated, and a through hole for pulling out the lead wire 33 is provided.

[0141] The resin cover 80 is formed of, for example, an insulating resin material. According to this, the insulation between the information acquisition module 40 and the LED module 10 can ...

Abstract

The invention discloses a light source for illumination and an illuminating device with the light source for illumination. A bulb lamp (1) as the light source for illumination comprises an LED module(10) and an information obtaining module (40), wherein the LED module (10) is provided with a substrate (11) and multiple light emitting elements (12) mounted on a main surface (11a) of the substrate(11); the information obtaining module (40) obtains information for controlling emitted light of the LED module (10); the substrate (11) is provided with a through hole (11b) penetrating through the substrate (11) in the thickness direction; the information obtaining module (40) is inserted in the through hole (11b) in a mode of protruding towards the side of the main surface (11a) of the substrate (11); and the front end part of the protruding direction of the information obtaining module (40) is positioned beyond a light emitting range determined by a light distribution angle of the light emitting element (12), nearest the through hole (11b), in the multiple light emitting elements (12).

Description

technical field [0001] The present invention relates to a light source for illumination and an illumination device. Background technique [0002] Conventionally, light bulb-shaped lamps (LED lamps) provided with semiconductor light emitting elements such as light emitting diodes (LED: Light Emitting Diode) are known (for example, refer to Patent Document 1). The LED lamp described in Patent Document 1 is equipped with a human sensor, and is turned on when a person is detected, and turned off when no person is detected. Accordingly, reduction in power consumption is attempted. [0003] (Prior art literature) [0004] (patent documents) [0005] Patent Document 1: Japanese Unexamined Patent Publication No. 2012-204213 [0006] However, in the above-mentioned conventional LED lamp, a reflector is arranged on the upper surface of the substrate on which the LEDs are arranged, and a human detection sensor is provided on the upper surface of the reflector. Therefore, the heat ...
