A full-circle LED light tube

Abstract

The invention relates to the field of lighting lamps and particularly relates to an all-period-luminosity LED lamp tube. The all-period-luminosity LED lamp tube comprises a lamp tube shell, a lamp core and enc covers, wherein the lamp core is mounted in the lamp tube shell, and the end covers are connected to two ends of the lamp tube shell; the lamp tube shell is of a circular pipe shape with two open ends, lamp core fixing brackets for fixing the lamp core are arranged at two ends of the lamp tube shell, a driving circuit assembly is arranged at one end of the lamp tube shell and is connected with one end of the lamp core, and the lamp core is of a prismatic shape; and a plurality of LED chips are uniformly arranged on the surface of a prism, and two ends of the lamp cores are fixed on the lamp core fixing brackets to make the axis of the lamp core coincided with the axis of the lamp tube shell. According to the structure, the LED lamp tube has an all-period-luminosity lighting function and is simple in structure, strong in heat dissipation capacity and long in service life.

Description

technical field [0001] The invention relates to the field of lighting fixtures, in particular to a full-circumference LED lamp tube. Background technique [0002] With the advent and popularization of LED lamps, incandescent lamps are gradually being abandoned by people. LED lamps have the characteristics of long life, high luminous efficiency, no radiation and impact resistance. [0003] However, due to the directivity of the light emitted by the LED light source itself, even after the light emitted by the diffusion cover is diffused, compared with the traditional incandescent light source that can be distributed in all directions, the light distribution angle of the existing LED lamp is still very narrow. The light angle is generally below 120°, and the light cannot reach the back of the lamp, which will form a dark shadow. [0004] Although some LEDs can achieve large-angle light distribution, they use a large number of optical components such as reflectors and lenses, a...

Problems solved by technology

Using this method first reduces the light efficiency of the LED, and secondly makes the LED lamp need a lot of compressed heat dissipation space when maintaining the replacement form, so that the temperature of the LED remains high during operation, and the power of the LED cannot be increased.

At the same time, the existing large-angle LED lamps all need to use a diffuser cover for astigmatism, and there is still a big gap between the lighting effect and the traditional incandescent lamp

[0005] In recent years, with the emergence of new materials and the progress of semiconductor manufacturing technology, there have been LED light bars that can expand the luminous angle. The LED light bar is to install a pair of LED chips back to back in the through hole of the chip holder. The superposition of the irradiation angles of the chips expands the luminous atmosphere of the LED light bar, but this kind of LED light bar can only increase the luminous angle of the LED light bar. Under the influence of the edge of the through hole, the illumination range of the two LED chips cannot be realized. There is no empty splicing, and there is no guarantee that the light emitted by the LED light bar is uniform and full-circumferential light
