Problems solved by technology

[0004] Although the technical solution disclosed in the above patent application solves the problem that the LED substrate of the LED fluorescent lamp is easily burned when the temperature of the power supply circuit board is too high, the temperature of the power supply circuit board still exists, which will still cause the temperature distribution in the lamp tube to be uneven. Local overheating occurs, which affects the service life of the lamp

Embodiment Construction

[0018] As shown in the accompanying drawings, a split-type lamp base power supply LED fluorescent lamp includes a power supply circuit board 1, a lamp tube 2, and an LED fluorescent lamp inside the lamp tube 2. The power supply circuit board 1 is electrically connected to the LED fluorescent lamp. The power supply circuit board 1 is packaged The cover 3 is arranged on one or both ends of the lamp tube 2, the power supply circuit board 1 is fixed in the packaging cover 3, and the packaging cover 3 and the lamp tube 2 are installed and fixed.

[0019] The power supply circuit board 1 part is separated from the heat generated by the light source part, and the heat is evenly distributed, which can effectively prolong the service life of the electrolytic capacitor. The power supply part is completely isolated from the lamp body, which also improves the safety and stability of the lamp.

[0020] The power circuit board 1 is arranged at both ends of the lamp tube 2 , that is, the pow...

Abstract

The invention discloses a split lamp holder power supply light-emitting diode (LED) fluorescent lamp, which comprises a power supply circuit board (1), a lamp tube (2) and an LED fluorescent lamp in the lamp tube (2), wherein the power supply circuit board (1) is electrically connected with the LED fluorescent lamp and is arranged at one end or both ends outside the lamp tube (2) by an encapsulation cover (3); and part of the power supply circuit board (1) is isolated from the lamp tube (2). The split lamp holder power supply LED fluorescent lamp has a good and more uniform radiating effect, the phenomenon of local overheating is prevented, and the prolongation of the service life of the lamp is facilitated.

Description

technical field [0001] The invention relates to an LED fluorescent lamp, in particular to an LED fluorescent lamp with a separate design of a power supply circuit board and a lamp tube, and belongs to the technical field of LED fluorescent lamp manufacturing. Background technique [0002] The LED fluorescent lamps currently on the market all adopt the structure that the power supply circuit board is packaged in the lamp tube. The heat dissipation effect of the lamps with such a structure is not good, and the lamps will be partially overheated. [0003] For example, the Chinese patent application with application number 201010278443 discloses an LED fluorescent lamp, which adopts a structure in which a power supply circuit board is packaged in a lamp tube. [0004] Although the technical solution disclosed in the above patent application solves the problem that the LED substrate of the LED fluorescent lamp is easily burned when the temperature of the power supply circuit boar...
