Waterproof connection structure of lighting tube in light fitting

Abstract

The invention discloses a waterproof connection structure matched between an end socket of a lighting tube in a light fitting and a slot of a plug socket. The outer peripheral surface (101) of the end socket is provided with at least one annular groove (102), wherein a sealing ring (3) is sleeved in the annular groove (102); the thickness of the sealing ring (3) is larger than the depth of the annular groove (102); the inner peripheral surface (201) of the slot of the plug socket has a taper; the end socket and the slot of the plug socket form a compacting seal through the sealing ring (3) and the taper of the inner peripheral surface (201); and the sealing ring (3) is matched with the taper of the inner peripheral surface (201) in a sealing mode for preventing water. The waterproof connection structure can be widely used in the field of light fittings.

Description

technical field [0001] The invention relates to a waterproof connection structure of a lamp tube in a lamp. Background technique [0002] With the mature development of LED technology, LED street lights have gradually replaced traditional street lights. Compared with traditional street lights, LED street lights not only have the advantages of long life and good chromaticity, but more importantly, they have a significant effect in energy saving. Generally, street lamps use a large lampshade to encapsulate the light source in the inner cavity to waterproof, but this appears to be large in size and not compact in structure; the existing more advanced LED street lamps use several LED unit lamp tubes to install on the street lamp rack. In the socket, but it is only a simple installation, no waterproof measures are taken in the structure, rainwater can easily enter the socket from the installation gap and cause a short circuit fault, etc., thus damaging the lamp.
