Abstract

The utility model provides a LED flourescent lamp comprising a lighting tube and two installing heads positioned at two ends of the lighting tube. The utility model is characterized in that the lighting tube is internally provided with a poling board on which is provided with a LED set, and all LEDs are electrically connected with a power supply electric control board which is enclosed in the lighting tube. Cold light emitting LEDs are arranged in a flourescent lamp tube through a concave possessing poling board and all LEDs are electrically connected with a power supply electric control board which is enclosed in the lighting tube, thereby enabling the utility model to overcome the shortcomings of current flourescent lamps of easy heat generation and damage as well as large electric consumption. Meanwhile, the utility model does not need a rectifier or a starter any longer, thereby being beneficial to the lowering of production cost and a structural simplification. Furthermore, thanks to the adoption of LEDs, the utility model also has the advantages of a longer service life which is more than 10 times that of current flourescent lamps and witnesses a total work time of more than 50,000h on a basis of round-the-clock operation per day, energy saving, absent environmental pollution, less power and greater brightness.

Description

The LED fluorescent lamp

Technical field

The utility model relates to a kind of fluorescent lamp, especially a kind of fluorescent lamp of making light source with LED.

Background technology

Used decades as illuminating fluorescent lamp, it brought many convenience for people's work, studying and living.But in today of scientific and technical develop rapidly, old-fashioned fluorescent lamp exists following point as the main light fixture of illumination: (1) is accompanied by heating often owing to fluorescent lamp is luminous, most of electric energy can not change into luminous energy, but be transformed into heat energy, not only power consumption, and can burn out fluorescent tube because of heating, thus influence its service life, generally have only two months time.(2), in glass tube, insert powder material usually or charge into gas, in case the fluorescent tube fragmentation will pollute the environment for the light that makes fluorescent lamp is soft.(3) need use rectifier when fluorescent lamp inserts the AC power of 220V, 50HZ, when turning on light starting device will be arranged, therefore, volume is bigger, and accessory is more.Therefore, be necessary prior art is improved.

Summary of the invention

For overcoming existing fluorescent lamp above shortcomings, it is a kind of simple in structure that the utility model provides, and can not generate heat long service life, bright LED fluorescent lamp.

The utility model is realized by following technical proposal: a kind of LED fluorescent lamp comprises it is characterized in that the installation head of fluorescent tube and lamp tube ends being provided with fagging in the fluorescent tube that LED pipe group is housed on the fagging, and each LED pipe power supply automatically controlled plate interior with being enclosed in fluorescent tube is electrically connected.

Fagging in the described fluorescent tube is made as the axial rased panel that adapts with inwall, is interval with the parabolic concave surface on the rased panel, and the LED pipe is installed in the focal position of parabolic concave surface, is used for fixing LED first, second by the setting that adds lustre to of parabolic concave surface, improves the brightness of LED.

Parabolic concave surface on the described fagging axially is made as row along fluorescent tube, perhaps left and right two row, and perhaps left, center, right three row or five are listed as, so that do the setting of concrete columns according to actual needs.

The automatically controlled plate of power supply in the described fluorescent tube is positioned at the fagging below, is used for installing electronic circuit component thereon, realizes being electrically connected to make things convenient for LED pipe and electronic circuit component.

The wall that is positioned at the automatically controlled plate of power supply below in the described fluorescent tube is provided with protruding, concave surface, is used for shading.

The utility model compared with prior art has following advantage and effect: adopt such scheme, being about to luminescent LED pipe is installed in the fluorescent tube by the fagging of being with the parabolic concave surface, and each LED pipe power supply automatically controlled plate interior with being enclosed in fluorescent tube is electrically connected, thereby having solved existing fluorescent lamp easily generates heat, fragile, the difficult problem that power consumption is big, simultaneously, no longer need rectifier and starting device during work, help reducing production costs simplified structure, the use of LED pipe in addition, improve 10 times or more than existing fluorescent lamp its service life, and non-stop run 24 hours every days reached more than 50000 hours, and the about energy of LED sight Lantern Festival is free from environmental pollution, power is little, the brightness height.
