Abstract

The utility model discloses an LED (Light-Emitting Diode) lamp tube for improving radiating. The LED lamp tube comprises a transparent tube body, an LED circuit board and a radiating fin, wherein the radiating fin is fixed at the back of the LED circuit board, the LED circuit board is clamped in the transparent tube body, a radiating groove is arranged at the back of the transparent tube body, and the radiating fin is exposed at the bottom of the radiating groove. The LED lamp tube for improving radiating has the advantages of simple structure and low cost; and as exposed at the bottom of the radiating groove in the air, the radiating fin is capable of quickly radiating heat generated by the LED circuit board, improving the radiating speed and prolonging the service life of the LED lamp tube. In addition, the width of the radiating groove is smaller, the conditions that a finger of a person is inserted into the radiating groove and is in contact with the radiating fin are avoided, the problem of electric leakage potential safety hazard is solved, and the safety of the LED lamp tube is improved.

Description

A kind of LED fluorescent tube that improves heat radiation

Technical field

The utility model relates to LED fluorescent tube technical field, especially relates to a kind of LED fluorescent tube that improves heat radiation.

Background technology

The LED fluorescent tube of prior art; Comprise printing opacity pipe, led circuit plate and radiator; Radiator is fixed in the back side of led circuit plate; The led circuit integrated circuit board is located in the printing opacity pipe; For example Chinese patent number is " 200820166263.X ", the patent name Chinese patent for " the LED fluorescent tube of band heat sink ", Chinese patent number be " 201010253227.9 ", patent name for the Chinese patent of " a kind of LED fluorescent tube " and Chinese patent number be the Chinese patent of " a kind of LED fluorescent tube " for " 201020160839.9 ", patent name.

In the LED fluorescent tube of prior art; The exposed electric leakage potential safety hazard that exists outside of radiator, led circuit plate and radiator are closed in the printing opacity pipe, and causes heat can't conduct fast; Reduce the radiating rate of led circuit plate and radiator, therefore be necessary to improve.

The utility model content

To the deficiency that prior art exists, the purpose of the utility model provides a kind of LED fluorescent tube that improves heat radiation, and it is simple in structure, and radiating rate is fast, and is safe, and cost is low, long service life.

To achieve these goals, the technical scheme that the utility model adopted is:

A kind of LED fluorescent tube that improves heat radiation comprises a light-transmitting tube body, led circuit plate and fin; Fin is fixed in the back of led circuit plate; The led circuit integrated circuit board is located in the light-transmitting tube body, and the back of light-transmitting tube body is provided with radiating groove, and fin exposes the bottom at radiating groove.

The back of said light-transmitting tube body constitutes said radiating groove to lower recess, and the both sides of radiating groove are that light-transmitting tube body is extended the cell wall that forms, and the bottom of radiating groove is said fin.

The cell wall of said radiating groove both sides forms a bending part to the bending of radiating groove lateral direction, and two side positions at the back of fin are respectively arranged with alar part, and the end of alar part is provided with a coupler body, and the coupler body hasp is in bending part.

Two groups of symmetrically arranged draw-in grooves of the internal face moulding of said light-transmitting tube body, the both sides of the edge difference inlay card of led circuit plate is in two groups of draw-in grooves.

Said radiating groove is parallel to the length direction of LED fluorescent tube.

After adopting said structure; The utility model is compared the advantage that is had with prior art: the utility model is simple in structure, and cost is low, and fin exposes the bottom at radiating groove; Fin is exposed in the air; The heat that fin can be produced the led circuit plate rapidly conducts, and improves radiating rate, improves the service life of LED fluorescent tube.On the other hand, the width of radiating groove is less, avoids people's finger to be inserted in the radiating groove, avoids people's finger contact heat spreader, solves the electric leakage potential safety hazard, the security that improves the LED fluorescent tube.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Fig. 1 is the LED lamp tube structure sketch map of the utility model.

Fig. 2 is the cutaway view in AA cross section among Fig. 1.

Among the figure: 1, light-transmitting tube body 2, led circuit plate 3, fin 4, radiating groove 5, bending part 6, alar part 7, coupler body 8, Plug Division.

The specific embodiment

The following stated is merely the preferred embodiment of the utility model, does not therefore limit the protection domain of the utility model.

Embodiment; See illustrated in figures 1 and 2: a kind of LED fluorescent tube that improves heat radiation comprises a light-transmitting tube body 1, led circuit plate 2 and fin 3; Fin 3 is fixed in the back of led circuit plate 2; Led circuit plate 2 is arranged in the light-transmitting tube body 1, and the back of light-transmitting tube body 1 is provided with radiating groove 4, and fin 3 exposes the bottom at radiating groove 4.Radiating groove 4 is parallel to the length direction of LED fluorescent tube.

The two ends of light-transmitting tube body 1 are respectively arranged with Plug Division 8.The lower surface of led circuit plate 2 is provided with some LED lamps.

The back of light-transmitting tube body 1 constitutes radiating groove 4 to lower recess, and the both sides of radiating groove 4 are that light-transmitting tube body 1 is extended the cell wall that forms, and the bottom of radiating groove 4 is a fin 3.

The cell wall of radiating groove 4 both sides forms a bending part 5 to radiating groove 4 lateral direction bendings, and two side positions at the back of fin 3 are respectively arranged with alar part 6, and the end of alar part 6 is provided with a coupler body 7, and coupler body 7 hasps are in bending part 5.Alar part 6 and coupler body 7 further improves radiating rates, simultaneously light-transmitting tube body 1 and radiating groove 4 had supporting role, increases the structural strength of light-transmitting tube body 1 and radiating groove 4, makes fin and radiating groove 4 Stability Analysis of Structures, is being heated or not yielding when stressed.

Two groups of symmetrically arranged draw-in grooves of the internal face moulding of light-transmitting tube body 1, the both sides of the edge difference inlay card of led circuit plate 2 is in two groups of draw-in grooves.
