Embodiment Construction

[0034] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings.

[0035] The following description will be illustrated with illustrations, wherein, according to an embodiment of the present invention, the LED circuit board 80 in the illustration is only an example and is not intended to limit the patent scope of the present invention. For example, the arrangement of the LED chips in the LED circuit board 80 is not limited to the one shown in the figure, it can be multiple in a single row or in multiple rows, and even a lens can be constructed on the LED chip, all of which are familiar to those skilled in the art. change. In a preferred embodiment, it is single row or double row, so that each row and each LED chip in the light bar can obtain the closest heat dissipation condition.

Abstract

The invention provides a light-emitting diode (LED) lamp tube, which comprises a lamp shell, wherein the lamp shell is an approximately semi-cylindrical elongated body; a platform is arranged in the elongated body; a circuit board comprising an LED chip is arranged on the platform; a plurality of radiating fins integrally molded in a shape of bat-like spread wings are arranged on an outer surface of the elongated body at intervals; an adjusting shaft is arranged at two ends of the approximate semi-cylinder; a plurality of racks are arranged on the circumference of the adjusting shaft, so that when a lamp tube device is arranged on a lamp tube bearing base provided with a corresponding tooth groove, rotary adjustment at different angles can be performed by taking a central axis of the adjusting shaft as an axis; and after the angle of the lamp tube is adjusted by the adjusting shaft, the lamp tube is fixedly locked through a fixing button and a screw. In addition, a waterproof rubber stopper is used for stopping an outlet hole on a side surface of the hollow adjusting shaft, and a power line can be connected with an LED circuit board through the outlet hole; therefore, the lamp tube can be tightly engaged and positioned on the bearing base. The LED lamp tube, similar to a bulb of a traditional street lamp, is a modular luminous element and is easy to assemble, and an individual lamp tube is convenient to maintain and replace.

Description

technical field [0001] The invention relates to a light-emitting diode lamp tube, in particular to a lamp tube used for outdoor lighting fixtures. Background technique [0002] The known street lamp structure is mostly a mercury lamp or a halogen lamp connected to a bent end of an upright light pole. One or more halogen bulbs or light-emitting elements are arranged in the lamp, and a reflector is provided in the lamp to reflect the light source to achieve the purpose of lighting at night. . [0003] Compared with LED lighting fixtures, traditional mercury lamp or halogen lamp type street lamps are lighting fixtures with high energy consumption and short lifespan. [0004] Light-emitting diodes have the characteristic of concentrated light beams, but the brightness of LEDs was not as good as it is now a few years ago. Therefore, they are generally only used in signal lights, rear lights or decorative lights, and thanks to the invention of blue LEDs and their recent price dec...
