Rotatable LED lamp tube

Abstract

The invention relates to a rotatable LED lamp tube comprising a lamp tube main body and rotary lamp caps at two ends of the lamp tube main body. Each rotary lamp cap comprises a fixing assembly and a rotary assembly sleeved on the end portion of the lamp tube main body, wherein indexing teeth are arranged in each fixing assembly, and locking teeth corresponding to the indexing teeth are arranged on each rotary assembly. The rotary assemblies rotate along with the lamp tube main body, the indexing teeth are arranged on the fixing assemblies, the rotary assemblies are provided with the locking teeth, when the locking teeth are meshed with the indexing teeth, the rotary assemblies and the fixing assemblies are fixed, and when the locking teeth are separated from the indexing teeth, the rotary assemblies and the fixing assemblies can rotate relatively. Through meshing and separation of the locking teeth and the indexing teeth, rotary locking and unlocking of the rotatable LED lamp tube can be achieved. Therefore, the meshing of the locking teeth and the indexing teeth enhances reliability of the rotary locking, and further improves use reliability of the rotatable LED lamp tube.

Description

technical field [0001] The invention relates to lighting equipment, in particular to a rotatable LED lamp tube. Background technique [0002] As a new generation of solid-state light source, Light Emitting Diode (LED) has many advantages such as long life, excellent anti-vibration performance and low power consumption. With the advancement of technology, its power and brightness are also increasing, and gradually It can replace all kinds of traditional light sources and is widely used in display, lighting and other fields, including replacing fluorescent tubes of various sizes. [0003] The existing technology of using LEDs to replace fluorescent tubes is to paste LED lamp beads on strip lamp panels, insert them into tubular shells, and then match lamp caps of various specifications at both ends to form LED lamp tubes. Unlike traditional fluorescent tubes that can emit light at 360 degrees, general LED tubes can only emit light on one side, and the angle of light does not e...

AI Technical Summary

Problems solved by technology

Unlike traditional fluorescent tubes that can emit light at 360 degrees, general LED tubes can only emit light on one side, and the angle of light does not exceed 180 degrees, which makes the same LED tube unable to adapt to the requirements of different environments for irradiation angles.

Some LED lamps can be rotated at the lamp head to adjust the irradiation angle, but the angle cannot be accurately controlled and there is no limit structure to lock on the selected angle. Due to the effects of gravity, vibration and other factors, the LED lamp will rotate soon. The selected angle fails, which reduces the reliability of the LED tube and may cause adverse consequences
