Embodiments of the invention

[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

1 to 3, the safety LED lamp tube of the preferred embodiment of the present invention includes: two plugs 11, 12, an electrode probe 13, a PC (polycarbonate) shell 14, and a light-emitting assembly 15 The power module 16, the trip switch 17, the trigger component 18, and the heat sink assembly 19.

[0020] There are two plugs 11, 12, and at least one plug 11/12 is provided with an outwardly extending electrode probe 13; in this embodiment, the LED tube is a single-ended power supply, and the two plugs include a plug 11 and a second plug 12, the electrode probe 13 and the stroke switch 17 are disposed on the first plug 11, the first plug 11 is used as a power supply end; and the second plug 12 is extended outward. For mounting the fixed card probe 20 .

[0021] The PC tube casing 14 is an elongated tubular hollow structure, and the first plug 11 and the second plug 12 are respectively sleeved at two ends, and the first plug 11, the second plug 12 and the PC tube 14 are formed. A light-emitting component 15 and a power module 16 are mounted in the cavity; a stroke switch 17 is connected to the power line 21 between the power module 16 and the electrode probe 13, and the stroke is 17 It is fixed in one of the plugs 11, and the end surface of the plug 11 is provided with a triggering member 18 that is triggered to close by the stroke of the stroke after the lamp is installed.
