Problems solved by technology

The heat is transferred to the human detection sensor, whereby the detection performance of the human detection sensor decreases
In addition, since the reflector is provided at the central portion of the upper surface of the substrate, the amount of light at the center of the LED lamp decreases, and light unevenness occurs in the emitted light.

Embodiment 1

[0041] [structure]

[0042] First, for the overall structure of the bulb-shaped lamp related to Example 1, use figure 1 as well as figure 2 Be explained.

[0043] figure 1 It is a notched perspective view of a part of the LED lamp 1 according to this embodiment. figure 2 It is a sectional view of the LED lamp 1 concerning this Example. Moreover, in figure 1 In , in order to show the LED module 10 inside the glove 50, a part of the glove 50 is cut away and shown.

[0044] and, in figure 1 as well as figure 2 In , the dotted line drawn along the vertical direction of the drawing shows the lamp axis (central axis) J of the light bulb-shaped lamp 1 . In this embodiment, the lamp axis J coincides with the axis of the globe 50 (globe axis). Furthermore, the lamp axis J is an axis that becomes the center of rotation when the lightbulb-shaped lamp 1 is attached to the socket of the lighting device, and coincides with the rotation axis of the base 60 .

Deformed example 1

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

[0126] Such as Figure 5 as well as Figure 6 As shown, the lightbulb-shaped lamp 101 differs from the lightbulb-shaped lamp 1 according to the first embodiment in that a reflector 70 is newly provided. Hereinafter, description will focus on differences from Embodiment 1, and description of common points will be omitted.

[0127] The reflector 70 is arranged around the information obtaining module 40 . In this modified example, the reflecting plate 70 is a cylindrical body whose axis is the penetration direction of the through hole 11b, and is also a cylindrical body w...

Deformed example 2

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

[0139] Such as Figure 7 As shown, the lightbulb-shaped lamp 201 differs from the lightbulb-shaped lamp 1 according to the first embodiment in that a resin cover 80 is newly provided. Hereinafter, description will focus on differences from Embodiment 1, and description of common points will be omitted.

[0140] Such as Figure 7 As shown, the resin cover 80 covers the information obtaining module 40 . Specifically, the resin cover 80 is a housing for accommodating the information obtaining module 40 , and has a through hole through which the lead wire 33 is pulled out.

[0141] The resin cover 80 is formed of, for example, an insulating resin material. Accordingly, insulation between the information obtaining module 40 and the LED module 10 can be ensured. The resin cover 80 may be formed o...

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 ...
