Embodiment approach 1

[0077] Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

[0078] Figure 1 to Figure 6 The straight tube lamp 100 of this Embodiment of this invention is shown. in, figure 2 is a perspective view showing the appearance of the straight tube lamp 100, figure 1 is along figure 2 A cross-sectional view of line A-A. image 3 is along figure 1 The cross-sectional view of the B-B line, Figure 4 is along figure 1 Cross-sectional view of line C-C. Figure 5 It is an exploded perspective view of main parts of the straight tube lamp 100 .

[0079] Such as figure 1 As shown, the straight tube lamp 100 of this embodiment includes a housing 6, an LED substrate 1, a plurality of LEDs 2, a heat dissipation member 3, a heat insulating member 4, a connector portion 5, a pair of joint portions 7, 9 and a pair of lamp caps 8, 8.

[0080] Such as figure 1 , figure 2 , image 3 As shown, the housing 6 is a str...

Embodiment approach 2

[0126] Hereinafter, other embodiments of the present invention will be specifically described with reference to the drawings. In addition, for convenience of description, members having the same functions as those used in Embodiment 1 are given the same reference numerals and descriptions thereof are omitted.

[0127] Figure 8 It is a sectional view of 100 A of straight tube lamps which concerns on other embodiment of this invention. Figure 8 Equivalent to Embodiment 1 image 3 , Figure 4 , a cross-sectional view of the central portion of 100A of straight tube lamps provided with LED 2 and a cross-sectional view of joint portion 7 of 100A of straight tube lamps are synthesized and shown.

[0128] The main difference between the straight tube lamp 100 of Embodiment 1 and the straight tube lamp 100A of this embodiment lies in the shape of the heat insulating member. Such as Figure 9 As shown, the heat insulating member 4A of the straight tube lamp 100A of this embodimen...

Embodiment approach 3

[0137] Hereinafter, another embodiment of the present invention will be specifically described with reference to the drawings. In addition, for convenience of description, members having the same functions as those used in Embodiments 1 and 2 are given the same reference numerals and description thereof will be omitted.

[0138] Figure 10It is a perspective view which shows the cross-sectional structure of the one end part of the longitudinal direction of the straight tube lamp 100B which concerns on another embodiment of this invention. The joint portion 30 attached to one end portion in the longitudinal direction of the housing 6C is composed of a main body portion 31 and a connector housing 32 fitted and attached to the main body portion 31 . The connector housing 32 is a member that holds the aforementioned connector for power supply, and functions as a part of the joint portion 30 by being fitted to the main body portion 31 . An opening 10 is formed in the connector ho...

Abstract

A straight tube lamp (100) is provided with an LED substrate (1) on which a plurality of LEDs (2) are mounted, a heat dissipating member (3) on which the LED substrate (1) is mounted and which dissipates heat from the LED substrate (1), and a cylindrical case (6) that accommodates the heat dissipating member (3). A heat insulating member (4) is provided between the heat dissipating member (3) and the case (6).

Description

technical field [0001] The invention relates to a straight tube lamp, in particular to a straight tube lamp using a solid light-emitting element as a light source. Background technique [0002] In recent years, solid-state light-emitting devices such as semiconductor lasers and light-emitting diodes have attracted attention as new light sources to replace incandescent lamps and fluorescent lamps as environmental awareness has increased. In particular, light-emitting diodes (hereinafter referred to as LEDs) have a long life and high light conversion efficiency, and LED lamps using LEDs as light sources are gaining attention. [0003] For example, Patent Document 1 discloses a straight tube lamp using LED as a light source. In the straight tube lamp, a rectangular substrate on which a plurality of LEDs are mounted is laminated on an elongated heat dissipation member extending in a longitudinal direction of the substrate, and is accommodated together with the heat dissipation ...
