Problems solved by technology

[0003] In the existing LED fluorescent lamps, the LED substrate and the power circuit board are directly fixed together. Since the power circuit board generates a lot of heat during use, while the temperature of the LED substrate is relatively low, the temperature of the power circuit board will be directly transmitted to the LED substrate. Easy to burn out the LED substrate
[0004] Secondly, the light-emitting angle of the LED substrate in the prior art is generally 120 degrees, which is relatively small, and cannot be applied to some fields that require a higher light-emitting range.

Abstract

The invention discloses an LED fluorescent lamp, which comprises a tubular lamp shade, two lamp holder covers arranged at both ends of the lamp shade, and at least one power circuit board, at least one LED substrate and at least one LED support for fixing the LED substrate, wherein the power circuit board, the LED substrate and the LED support are accommodated in the tubular lamp shade; at least one LED lamp is packaged on the at least one LED substrate; the two lamp holder covers are respectively provided with a plug butted with an external power socket; the at least one power circuit boardis electrically connected with the plug, the LED substrate and the LED lamp packaged on the LED substrate; and a gap is arranged between the at least one LED substrate and the at least one power circuit board. Due to the fact that the gap is arranged between the LED substrate and the power circuit board of the LED lamp, the heat transfer can not be directed generated between the LED substrate andthe power circuit board, thereby protecting the LED substrate.

Description

technical field [0001] The invention relates to the field of LED fluorescent lamps, in particular to an LED fluorescent lamp capable of preventing LED substrates from burning out. Background technique [0002] As a cold light source, fluorescent lamps are widely used in industrial and civil lighting compared with traditional incandescent lamps. With the continuous development of semiconductor and electronic technology, LED has been recognized by the market as a fluorescent lamp for its superior energy-saving performance and longer service life. [0003] In the existing LED fluorescent lamps, the LED substrate and the power circuit board are directly fixed together. Since the power circuit board generates a lot of heat during use, while the temperature of the LED substrate is relatively low, the temperature of the power circuit board will be directly transmitted to the LED substrate. It is easy to burn out the LED substrate. [0004] Secondly, the light emitting angle of th...
