Embodiment approach 1

[0130] (Overall structure of a bulb-shaped lamp)

[0131] First, refer to Figure 1 ~ Figure 3 , the overall structure of the light bulb-shaped lamp 100 according to this embodiment will be described.

[0132] figure 1 It is a perspective view of the lightbulb-shaped lamp concerning Embodiment 1. exist Figure 1 ~ Figure 3 , the X, Y, and Z directions are orthogonal to each other. The X, Y, and Z directions shown below are also perpendicular to each other.

[0133] figure 2 It is an exploded perspective view of the light bulb-shaped lamp concerning Embodiment 1.

[0134] image 3 It is a front view of the light bulb-shaped lamp which concerns on Embodiment 1. In addition, in image 3 In , a portion of the lighting circuit 180 and the lead wires 170a and 170b for power supply and maintenance located inside the lamp base 190 are indicated by dotted lines.

[0135] The bulb-shaped lamp 100 is a bulb in which a base 190 is attached to a translucent globe 110 . The LED ...

Deformed example 7

[0360] Figure 15 It is a sectional view for explaining the fixing structure according to Modification 7 of Embodiment 1. In Modification 7 of Embodiment 1, the fixing structure of 200N of LED modules is demonstrated.

[0361] Hereinafter, the lightbulb-shaped lamp according to Modification 7 of Embodiment 1 is also referred to as lightbulb-shaped lamp A17.

[0362] In Modification 7 of Embodiment 1, with Figure 14 (Modification 6 of Embodiment 1) differs in the position fixed by the lead wires 175a, 175b and the fixing wires 161a, 161b. The structure other than the structure of the fixed base 210 n is the same as that of the sixth modification of Embodiment 1, and therefore detailed description thereof will not be repeated.

[0363] The shape of the base 210n is a quadrangular plate shape. That is, the base 210n has four corners (ends).

[0364] Such as Figure 15 As shown, the lead wire 175a is provided such that the bent portion 18 of the lead wire 175a sandwiches on...

Embodiment approach 2

[0517] (Overall structure of a bulb-shaped lamp)

[0518] First, refer to Figure 23 ~ Figure 25 The overall structure of 100 A of lightbulb-shaped lamps concerning this Embodiment 2 is demonstrated.

[0519] Figure 23 It is a perspective view of the lightbulb-shaped lamp concerning Embodiment 2.

[0520] Figure 24 It is an exploded perspective view of the light bulb-shaped lamp concerning Embodiment 2.

[0521] Figure 25 It is a front view of the light bulb-shaped lamp which concerns on Embodiment 2.

[0522] Bulb shaped lamp 100A with figure 1 Compared with the light bulb-shaped lamp 100 of the above-mentioned lightbulb-shaped lamp 100, it is different in that lead wires 130a, 130b are provided instead of lead wires 170a, 170b, and LED module 200N is provided instead of LED module 200. Since the structure of the lightbulb-shaped lamp 100A other than that is the same as that of the lightbulb-shaped lamp 100, detailed description is not repeated.

[0523] The leads ...

Abstract

A bulb-type lamp (100) is provided with: an LED module (200) having a base (210), and semiconductor light emitting elements (300) mounted on the base (210); and lead lines (170a, 170b) for supplying power to the LED module (200). The base (210) is supported by the lead lines (170a, 170b).

Description

technical field [0001] The present invention relates to a light bulb-shaped lamp provided with a semiconductor light emitting element and a lighting device provided with the light bulb-shaped lamp. Background technique [0002] Light Emitting Diode (LED: Light Emitting Diode), which is a semiconductor light emitting element, is smaller, more efficient, and has a longer lifespan than conventional lighting sources. In response to market demand for energy saving or resource conservation in recent years, bulb-shaped lamps using LEDs (hereinafter referred to as LED bulbs) instead of conventional incandescent bulbs using spiral filaments and lighting devices equipped with such bulb-shaped lamps demand is increasing. [0003] LEDs are known to have a reduced light output and a shorter lifetime as their temperature rises. Therefore, in order to suppress the temperature rise of the LED, in the conventional LED light bulb, a metal frame is provided between the hemispherical bulb and...
