Abstract

The utility model discloses an LED fluorescent tube, which comprises a long strip-shaped PCB board, LED luminous bodies, a radiator, a lampshade and two lamp holders. The radiator is semi-cylindrical. The two sides of the lower end of the radiator are equipped with grooves. The lampshade is hollow semi-cylindrical. The two sides of the upper end of the lampshade are equipped with flanges extending inwardly. A plurality of rows of LED luminous bodies are arranged on the PCB board. The PCB board is fixed to the lower end surface of the radiator. The two flanges at the upper end of the lampshade are clamped with the grooves at the two sides of the lower end of the radiator. The lampshade and the two ends of the radiator are fixed to the two lamp holders at the same time. The two lamp holders are respectively and fixedly equipped with two metal pins. The spacing between the two metal pins is the same with the spacing between the metal tube pins of a T8 fluorescent tube. The parts of the two metal pins of each lamp holder extending into the interior of the tube are connected in parallel with each other and are connected with the PCB board through a lead. The LED fluorescent tube has the advantages of high universality and long service life. The luminescence of the LED fluorescent tube without flickers will protect the eyes of a user.

Description

The LED fluorescent tube

Technical field

The utility model relates to field of illumination lamp technology, especially a kind of luminous fluorescent tube of LED that utilizes.

Background technology

The fluorescent tube that people knew is a kind of fluorescent tube; Fluorescent tube is processed by glass, and the inwall of fluorescent tube scribbles fluorescent material, and the two ends of fluorescent tube respectively are provided with two metal pin; The subject matter that fluorescent tube in use can exist is; The one, broken easily because of fluorescent tube is processed by glass, the fluorescent material in the fluorescent tube of broken back pollutes the environment; The 2nd, the life-span of fluorescent tube is shorter, need often to change, and waste of manpower, discarded fluorescent tube reclaims difficulty, and is unfavorable to environment; The 3rd, fluorescent tube can glimmer in luminous process, and human eye is had certain injury.

The utility model content

The technical problem that the utility model will solve provides a kind of LED fluorescent tube, highly versatile, and the life-span is long, and luminous the flicker has protective effect to human eye.

For achieving the above object, the technical scheme of the utility model is: a kind of LED fluorescent tube comprises pcb board, LED illuminator, radiator, lampshade, two lamp holders of strip; Radiator is half-cylindrical, and the both sides, lower end of radiator are provided with groove, and lampshade is that hollow is half-cylindrical; There is the edge of a wing of inside extension the both sides, upper end of lampshade; Distribute on the pcb board and arrange the LED illuminators more, pcb board is fixed on the lower surface of radiator, and two edges of a wing of lampshade utilization upper end are connected on the groove of both sides, radiator lower end; Two ends while and two lamp holders of lampshade and radiator fix; Respectively be fixed with two metal pin on two lamp holders, the spacing of two metal pin is identical with the spacing of T8 fluorescent tube metal pin, and two metal pin of each lamp holder stretch into the inner part of fluorescent tube and connect together and be connected with pcb board by a lead.

Further, described fansink designs is a hollow, and the centre is provided with many reinforcements, helps saving radiator material.

On the face of cylinder of radiator, offer a plurality of louvres, help increasing the radiating effect of LED illuminator.

Preferred radiator is processed by aluminium alloy, and good heat dissipation effect and cost are lower.

The Design of length of described fluorescent tube is 1230mm or 926mm or 620mm, further improves versatility.

The drive circuit of the LED illuminator of the utility model is external; After being replaced with the LED driver module to the ballast on the existing fluorescence lamp bracket; Because of the metal pin of the spacing of the utility model metal pin and existing fluorescent tube is identical, profile is close, and length can be corresponding with the fluorescent tube of variant wattage; Therefore the utility model can directly be replaced traditional fluorescent lamp tube and is inserted on the fluorescence lamp bracket and uses highly versatile.

On the other hand, because life-span of LED illuminator is long and can not glimmer when luminous, so the life-span of the utility model is longer, reduces and changes number of times, has practiced thrift manpower, does not glimmer because of luminous simultaneously, helps protecting people's eyes.

The specific embodiment

Below in conjunction with accompanying drawing and concrete embodiment the utility model is done further explain.

Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of LED fluorescent tube comprises the pcb board 1, LED illuminator 2, radiator 3, lampshade 4 of strip, two

lamp holders

5,6; Radiator 3 is half-cylindrical; The both sides, lower end of radiator 3 are provided with

groove

31,32, and lampshade 4 is that hollow is half-cylindrical, and there is the edge of a

wing

41,42 of inside extension the both sides, upper end of lampshade 4; Many row LED illuminators 2 distribute on the pcb board 1; Pcb board 1 is fixed on the lower surface of radiator 3, and lampshade 4 utilizes two edges of a

wing

41,42 of upper end to be connected on the

groove

31,41 of both sides, radiator 3 lower end, and two ends while and two

lamp holders

5,6 of lampshade 4 and radiator 3 fix; Be fixed with two

metal pin

51,52 on the lamp holder 5; The spacing that is fixed with 61,62, two

metal pin

51,52 of two metal pin or 61,62 on the lamp holder 6 is identical with the spacing of T8 fluorescent tube two ends pin, and lamp holder 5 or two

metal pin

51,52 or 61,62 of 6 stretch into the inner part of fluorescent tube and connect together and be connected with pcb board 1 by a lead.

Radiator 3 is designed to hollow, and the centre is provided with many reinforcements 33.

On the face of cylinder of radiator 3, also can process a plurality of louvres 34.

Preferred radiator 3 is processed by aluminium alloy.

T8 fluorescent tube 40W length commonly used is that 1230mm, 30W length are that 926mm, 20W length are 620mm; Therefore the Design of length of this LED fluorescent tube is 1230mm or 926mm or 620mm, the long fluorescent tube of length according to brightness require to arrange more LED illuminator 2 on the pcb board 1.

When the utility model uses; Existing fluorescence lamp bracket capable of using; Be replaced with the LED driver module to the ballast on the fluorescence lamp bracket, the utility model utilizes the

metal pin

51,52 and 61,62 at two ends to be plugged on just can the luminous effect of playing illumination on the lamp socket at fluorescence lamp bracket two ends.

Below only be preferred embodiment of the utility model, those skilled in the art makes the protection domain that the change that is equal to all falls into this case by claim.
