Abstract

The invention discloses an LED (Light-emitting Diode) tubing lamp, which comprises a lamp tube, a central column, a plurality of LED chips, a fixing piece, a connecting board and a lamp cap, wherein the central column is provided with a plurality of slots, a high reflecting material is arranged on the slots, the LED chips are arranged on the slots to form a light source with 360-degree irradiation, and the central column is arranged in the lamp tube and is fixedly connected with the lamp cap through the fixing piece and the connecting board. The LED tubing lamp disclosed by the invention has 360-degree lighting, so the irradiation range of the tubing lamp is enlarged, and the light can more uniform so as to solve the glaring problem; and the lighting rate of the whole lamp is enlarged, the light efficiency of the whole lamp is improved, light-induced heat effect is reduced, and the stability and the reliability of the system are improved.

Description

technical field [0001] The invention relates to the technical field of LEDs, in particular to an LED tube lamp. Background technique [0002] At present, the light output angle of LED tube lights is generally only 180 degrees, and the light intensity on both sides of the light-emitting surface is significantly smaller than the middle light intensity, which not only causes severe glare but also has a far difference from the 360-degree light emission characteristics of traditional tube lights. Contents of the invention [0003] The problem to be solved by the present invention is to provide an LED tube lamp to overcome the defects of the existing lamp tubes in the irradiation range and uneven light. [0004] In order to achieve the above purpose, the technical solution of the present invention provides an LED tube lamp, which includes a lamp tube, a central column, a plurality of LED chips, a fixing piece, a connecting plate and a lamp holder; several grooves are arranged on...
