Abstract

The utility model discloses a light-emitting diode (LED) lamp tube improved structure. The structure mainly comprises a glass lamp tube, a metal heat dissipation base, an LED chip circuit board and two electrode seal covers, the glass lamp tube is capable of conducting heat and transmitting light, the metal heat dissipation base is strip-shaped and has curved radian, the rear of the metal heat dissipation base is stuck on the inner wall of the glass lamp tube through a heat conducting glue, the LED chip circuit board is configured on a placing portion in the front of the heat dissipation base so as to be connected with an LED drive circuit, the two electrode seal covers are sleeved on two openings at two ends of the glass lamp tube, inserting portions are arranged in the two electrode seal covers so that two ends of the heat dissipation base can be inserted and fixed, and a tension which upwards pulls is provided. Thereby, the combined glass lamp tube and the metal heat dissipation base have upwards jacking power, the middle heat dissipation base is connected with the inner wall of the lamp tube in a close attaching mode, droop and falling of the glass lamp tube and the metal heat dissipation base caused by the fact that the LED is heated when the LED is lightened can be prevented, due to the fact that the close attaching is necessary for the heat conduction, the heat can be effectively conducted to the exterior of the whole glass lamp tube and uniformly dissipated, the normal operation of the internal LED can be maintained, and the service life is effectively prolonged.

Description

The LED lamp tube modified structure

Technical field

The utility model relates to a kind of LED lamp tube modified structure, espespecially at the glass lamp inwall of heat conduction printing opacity, is adhesive with the curved heat dissipation metal pedestal of strip arc with heat-conducting glue, and forms the good LED fluorescent tube of heat radiation uniformly light-emitting degree.

Background technology

Fluorescent lamp is the illuminations that can not lack in the modern life, along with the scientific and technological progress technology is increasingly mature, the LED of a new generation has high brightness, reaction is fast, volume is little, low power consumption, energy-conservation, use safety and long advantage of life-span, so the equal active development LED of industry fluorescent tube replaces traditional fluorescent lamp.

But because the high-capacity LED input power only has 15～20% to convert light to, all the other 80～85% convert heat to; If not yet in effect the processing in good time of these heat energy discharged, will make LED crystal grain boundary excess Temperature, and cause the problems such as luminous efficiency decay, life-span reduction, be affect LED illumination Related product good and bad crucial.

At present, advanced known LED lamp tube structure mainly comprises: lamp housing, be the rectangular aluminium extruded type body of semicolumn, and the lamp housing inner face is for configuration led chip circuit board; Lampshade is relative semicolumn elongate body, is made of plastics or acryl material; Wherein be provided with the Access Division in lampshade and lamp housing bilateral symmetry, make both can be to forming a fluorescent tube, again in the built-in led drive circuit of lamp housing hollow sandwich, or led drive circuit directly is configured in the electrode enclosure at glass lamp two ends, and envelope forms the LED fluorescent tube that appearance has larger area of dissipation.

But this known LED lamp tube structure still has following shortcoming on making and using:

1. although the area of dissipation of lamp housing effectively strengthens, and makes required metal material and also and then increases, the fluorescent tube weight of composition is increased, relative cost also and then improves.

2. lampshade is made of plastics or the acryl material of atomizing, and light transmission is not good enough less than traditional glass lamp, and light source is obstructed illuminating effect is had a greatly reduced quality.

3. fluorescent tube is comprised of lamp housing and the lampshade of two kinds of unlike materials, causes easily heat radiation uneven during application, and the difference of expanding with heat and contract with cold on both sides causes fluorescent tube to produce distortion up and down.

Summary of the invention

Technical problem to be solved in the utility model is: for above-mentioned the deficiencies in the prior art, provide a kind of LED lamp tube modified structure.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of LED lamp tube modified structure, the led chip circuit board that mainly comprise glass lamp, is connected with led drive circuit, and two electrode enclosures, this glass lamp is the hollow circular cylinder of heat conduction printing opacity, and its two ends are provided with opening; This two electrode enclosure is set in this glass lamp both ends open, consists of with led drive circuit to be electrically connected; Be characterized in: also comprise the heat dissipation metal pedestal, be the strip of crooked radian, the cooling base front is provided with positioning part, and the back of cooling base is pasted on the glass lamp inwall with heat-conducting glue; This led chip circuit board arrangement is at the positioning part of cooling base, to connect this led drive circuit; Be provided with the Plug Division in this two electrode enclosure, it is fixing to peg graft for the cooling base two ends, and the tension force of pulling is provided.

Described cooling base section is arciform, has little prominent hogback in the back, and these cooling base both sides are provided with the guide rail tab, and the front is provided with the raceway groove of indent, to consist of described positioning part.

Described electrode enclosure is engaged by pin cover plate and short cylinder and forms, and the inner and upper in the open limit of short cylinder is embedded with L shaped plate, to consist of described Plug Division.

Described cooling base is that aluminium extruded type is rectangular; And this led drive circuit Tibetan is contained in wherein the inside of electrode enclosure on one side.

By this, make the glass lamp of composition and heat dissipation metal pedestal because the strength on upper top is arranged, middle cooling base can be close to tube inner wall and link to each other, make glass lamp and heat dissipation metal pedestal can not produce the sagging phenomenon that comes off because LED lights heating, because of closely connected be the necessary condition of heat conduction, evenly leave so heat effectively can be transmitted to whole glass lamp outside, make inner LED keep normal operation and effectively promote service life.
