Abstract

The invention discloses a hollowed-out lamp tube. The hollowed-out lamp tube comprises a cylindrical tube body and a mounting plate, wherein the tube body is made of metal, and the mounting plate is fixed to the lower end of the tube body. The tube body is provided with an upper sealing segment, a lower sealing segment and hollowed-out parts located between the upper sealing segment and the lower sealing segment. The hollowed-out parts comprise the multiple first hollowed-out parts and the multiple second hollowed-out parts, wherein the first hollowed-out parts and the second hollowed-out parts are evenly distributed on the outer circumferential surface of the tube body, and the first hollowed-out parts and the second hollowed-out parts are arranged in an alternating mode. Each first hollowed-out part comprises a pair of axial open grooves and a middle hollowed-out groove located between the axial open grooves. Each second hollowed-out part comprises a plurality of upper hollowed-out parts, a plurality of hollowed-out parts and a plurality of middle hollowed-out parts. The hollowed-out lamp tube is simple in structure, easy to manufacture, and good in heat dissipation effect; when the hollowed-out lamp tube is used, a generated shadow pattern can be clear and complete, and the boundary of the shadow is not fuzzy.

Description

technical field [0001] The invention relates to the technical field of lighting fixtures, and more specifically relates to a hollowed-out lamp tube for lighting fixtures. Background technique [0002] Existing LED light sets are widely used in many lighting fields such as indoor and outdoor functional lighting, decorative lighting and landscape lighting as a new type of green and environment-friendly light source. Patent application number CN 201110290531.5 Application date: 2011-09-29 The Chinese invention patent discloses a kind of LED lamp tube, including a light-transmitting shell, lamp caps located at both ends of the light-transmitting shell for providing power, located inside the light-transmitting shell The LED unit includes an LED chip and an encapsulating resin covering the LED chip. Each LED unit is arranged along the axis of the lamp tube. The lower part of the LED unit is connected to the heat dissipation block. As far as the legs on the outside of the light-tr...
