Problems solved by technology

[0004] However, the heat sink is made of aluminum and has conductivity, but it is not grounded when the LED lamp is attached to the lighting fixture.
Therefore, if current leaks from the LED module or lighting fixture to the heat sink, there is a risk of electric shock if it touches the heat sink
In particular, in the case of a DC lighting type LED lamp, the ground voltage of the radiator becomes the simple sum of the power supply voltage and the lamp voltage, which is greater than the actual value of the ground voltage in the case of an AC lighting type LED lamp, and there is a risk of electric shock. larger

no. 1 Embodiment approach ）

[0056] Such as figure 1 and figure 2 As shown, the straight-tube LED lamp (hereinafter referred to as "lamp") 10 of this embodiment includes: a straight tube 12 containing a plurality of light-emitting diodes (hereinafter referred to as "LED") 110; a first lamp base 14 for It is used for power supply connection with a plurality of LED110; and the second lamp base 15 is used for grounding. The first base 14 is provided on one end side of the straight tube 12 in the axial direction, and the second base 15 is provided on the other end side of the straight tube 12 in the axial direction. A plurality of LEDs 110 are included in the LED module 11 . The straight pipe 12 is composed of a radiator 120 and a cover 125 .

[0057] The LED module 11 has a long linear substrate 111 . On the mounting surface 112 of the board 111 , along the longitudinal direction of the board 111 , a plurality of LEDs 110 are mounted linearly, for example, in a row, and one thermal fuse 114 and one curr...

no. 2 Embodiment approach ）

[0086] When the above-mentioned straight tube type LED lamp has the same size and base as the straight tube type fluorescent lamp, there is a possibility that a lighting fixture having a lighting circuit for the straight tube type fluorescent lamp is incorrectly connected.

[0087] Figure 7 A and 7B are external perspective views of the straight tube type LED lamp 10 for solving the above-mentioned problems. For the sake of clarity, the same symbols as those in the first embodiment are assigned to the same elements.

[0088] This lamp 10 includes a single straight tube 22 formed of a translucent synthetic resin material. In addition, it is not limited to this, and the straight tube 22 may be a glass tube. A first cap 14 for power supply is provided on one axial end side of the straight tube 22 , and a second cap 15 for grounding is provided on the other axial end side of the straight tube 22 .

[0089] Inside the straight pipe 22 is housed a substrate made of a printed cir...

no. 3 Embodiment approach ）

[0129] When the straight tube 22 is formed of a light-transmitting synthetic resin material, the straight tube type LED lamp may move in the longitudinal direction due to bending, thermal expansion, and thermal contraction of the straight tube type LED lamp.

[0130] Figure 19 A lighting fixture 19 for solving the above-mentioned problems is shown. For the sake of clarity, the same symbols as those in the first or second embodiment are assigned to the same elements. The lighting fixture 19 is a built-in lighting fixture for one or more straight-tube fluorescent lamps, and includes one or more straight-tube LED lamps 10 . In addition, the lighting fixture 19 is not limited to a built-in lighting fixture, but can also be applied to a direct mount lighting fixture.

[0131] The lighting fixture 19 includes: a long frame body 191 with an open lower surface (refer to Figure 9 ), embedded in the ceiling surface; the first and second lamp holders 37, 38 are arranged oppositely a...

Abstract

Disclosed is a straight tube LED lamp provided with a straight tube containing a plurality of light emitting diodes on the inside, a first cap for feeding power to the light emitting diodes, provided on one end of the straight tube in the axial direction, and a second cap for grounding provided on the other end of the straight tube in the axial direction. A first terminal for electrical connection to a power feeding terminal of a first lamp socket is provided in the first cap. A second terminal for electrical connection to a grounding terminal of a second lamp socket is provided in the second cap.

Description

technical field [0001] The present invention relates to a straight-tube LED (light-emitting diode) lamp, a lamp holder group connected to the straight-tube LED lamp, and a lighting appliance using the straight-tube LED lamp and the lamp holder group. Background technique [0002] In order to reduce the frequency of replacement due to lifespan and realize power saving, LED lamps with a longer life and power saving than fluorescent lamps have been proposed as a substitute for fluorescent lamps (for example, Japanese Patent Application Publication Nos. 2008-103304, 2009-266432 and 2008-282793). For example, a straight-tube LED lamp, which is a substitute for a straight-tube fluorescent lamp, includes an elongated substrate having a length corresponding to that of the fluorescent lamp, and a plurality of LEDs mounted on the substrate along the longitudinal direction. In addition, an aluminum heat sink constituting a part of the case is mounted on the opposite side of the substr...
