Abstract
The invention relates to the technical field of an LED (light emitting diode) and particularly relates to an LED lamp tube. The LED lamp tube comprises a light transmitting shell, lamp caps and LED units, wherein the lamp caps are arranged on the two ends of the light transmitting shell and are used to provide power supply, the LED units are arranged in the light transmitting shell, each LED unit comprises an LED wafer and packaging resin covered on the LED wafer, each LED unit is arranged in a mode of extending along the axial direction of the lamp tube, heat dissipation pieces are connected under the LED units, and the lower end of the heat dissipation piece is provided with a supporting foot extending to the outside of the light transmitting shell. The LED lamp tube provided by the invention can better realize heat dissipation; and meanwhile, the structure is simple, the wiring can be easy to realize, and thus the LED lamp tube is realistically possible to be promoted and put into practice.
Description
Technical field
The present invention relates to the LED technical field, specifically, relate to a kind of LED fluorescent tube.
Background technology
LED can directly be converted into light to electricity; Simultaneously; LED has long, characteristics such as light efficiency is high, radiationless, shock resistance and low-power consumption of life-span, along with reaching its maturity with perfect of photoelectricity industry technology, for save electricity satisfies energy-conservation and environmental protection requirement; The simultaneous adaptation requirements of different users, more and more manufacturing enterprises have developed the LED fluorescent tube and have replaced the fluorescent lamp in the conventional art.
LED fluorescent tube in the conventional art is the fluorescent tube set inside one row LED luminescence unit at printing opacity; But; The fluorescent tube of this project organization exists the problem of heat radiation usually, and the heat that LED produces in the course of the work need distribute through certain approach usually; If deal with improperly, then can reduce the service life of LED fluorescent tube greatly.
The manufacturer that some production technology is comparatively advanced can connect fin in bottom, LED unit, then each fin is coupled together; Distribute through lamp tube ends, this radiator structure design need couple together each fin; The interruption at middle part will influence radiating effect.
Therefore, in order to overcome the deficiency of prior art, adapt to the needs of reality, be necessary to design a kind of LED fluorescent tube that can fine heat radiation.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, adapt to the needs of reality, a kind of novel LED fluorescent tube that can fine heat radiation is provided.
In order to realize the object of the invention, the technical scheme that the present invention adopts is:
A kind of LED fluorescent tube; Comprise light transmitting shell, be positioned at the crown top of burner that the light transmitting shell two ends are used to provide power supply, be located at the inner LED unit of light transmitting shell; Said LED unit comprises LED wafer and the potting resin that covers the LED wafer; Each LED unit extends along the fluorescent tube axis direction arranges that the below of said LED unit is connected with radiating block, and the lower end of said radiating block is provided with and extends to the outside leg of light transmitting shell.
The shape that said potting resin and the transverse cross-sectional combinations of radiating block form is identical with the shape of light transmitting shell.
Said potting resin and radiating block are semi-cylindrical.
Beneficial effect of the present invention is:
LED fluorescent tube of the present invention can be good at realizing dispelling the heat, and simple in structure, connects up easily, has the realistic possibility of promotion and implementation.
Description of drawings
Fig. 1 is a sectional structure sketch map of the present invention;
Fig. 2 analyses and observe enlarged diagram for the A-A of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified:
Embodiment: referring to Fig. 1, Fig. 2.
A kind of LED fluorescent tube; Comprise light transmitting shell 1, be positioned at the crown top of burner 5 that light transmitting shell 1 two ends are used to provide power supply, be located at the LED unit 2 of light transmitting shell 1 inside; Said LED unit 2 comprises LED wafer 21 and the potting resin 22 that covers the LED wafer; Each LED unit 2 extends along the fluorescent tube axis direction arranges that the below of said LED unit 2 is connected with radiating block 3, and the lower end of said radiating block 3 is provided with the leg 4 that extends to light transmitting shell 1 outside.
Some manufacturer can connect fin in 2 bottoms, LED unit, then each fin is coupled together; Crown top of burner place through lamp tube ends distributes, and this radiator structure design need couple together each fin; The interruption at middle part will influence radiating effect.
Structural design of the present invention makes heat that the LED unit distributes directly import the outside of light transmitting shell 1 through the leg of radiating block 3 lower ends, and radiating efficiency is high, good heat dissipation effect.
Because the radiating block structural design that the below exists; Can light transmitting shell 1 be designed to the version of part printing opacity, promptly near the top of LED unit as main transmittance section, and the radiating part of below; The requirement of light transmission is low, can be light-proof material even.
The shape that said potting resin 22 and the transverse cross-sectional combinations of radiating block 3 form is identical with the shape of light transmitting shell 1.Like this, radiating efficiency is higher, and whole fluorescent tube weight ratio everywhere is balanced.
Said potting resin 22 is semi-cylindrical with radiating block 3, and such structural design is in order to adapt in the prior art lamp tube structure of oval column.If lamp tube structure is other shapes, so, the shape that potting resin and radiating block combine also can be made corresponding change, and this is not need performing creative labour and the reasoning that can obtain easily, does not give unnecessary details at this.
LED fluorescent tube of the present invention can be good at realizing dispelling the heat, and simple in structure, connects up easily, has the realistic possibility of promotion and implementation.
What embodiments of the invention were announced is preferred embodiment, but is not limited thereto those of ordinary skill in the art; Very easily, understand spirit of the present invention, and make different amplifications and variation according to the foregoing description; But only otherwise break away from spirit of the present invention, all in protection scope of the present invention.
