Abstract

The utility model relates to an LED (Light Emitting Diode) lamp tube with a high-efficiency heat dissipation function and belongs to the technical field of LED lighting. The LED lamp tube comprises a lamp shell, an aluminum substrate, an LED integrated chip circuit block, a terminal and a side cover, wherein the LED integrated chip circuit block is arranged in the lamp shell through the aluminum substrate; the terminal is used for packaging the lamp shell; a slot is arranged in the lamp shell; the aluminum substrate is inserted into the lamp shell through the slot; the aluminum substrate is provided with a plurality of heat dissipation teeth; and a plurality of heat dissipation holes are formed in the lamp shell at intervals corresponding to the heat dissipation teeth. The heat dissipation area is effectively increased through the heat dissipation teeth arranged on the upper surface of the aluminum substrate, and meanwhile, the heat generated by a lamp bulb and the like can be quickly dissipated through the heat dissipation holes formed in the lamp shell at intervals, so that the problem that the heat generated by a light emitting diode cannot be timely conducted out because the heat is conducted to the aluminum substrate to be dissipated through heat conducting silicone grease and the heat conducting silicone grease becomes dry after long-term use in the prior art is solved. The heat dissipation effect is effectively improved.

Description

A kind of LED fluorescent tube of high efficiency and heat radiation
Technical field
The utility model relates to a kind of LED fluorescent tube of high efficiency and heat radiation, belongs to the LED lighting technical field.
Background technology
The heat radiation of LED light fixture always is that industry is in pursuit, the topic that is improving, the design of existing LED lamp is often dispelled the heat and is difficult to reach requirement, some light fixtures are between aluminium base and fin, also to add plastic bushing to increase the reliability of insulation, and coat heat-conducting silicone grease to improve heat-sinking capability, the heat that the LED light fixture produces in luminescence process, be transmitted on the aluminium base by heat-conducting silicone grease and dispel the heat, after time is long, heat-conducting silicone grease can become dry, and the heat that causes light emitting diode to produce can't in time conduct.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is, a kind of LED fluorescent tube of simple in structure, material consumption is few, cost is low high efficiency and heat radiation is provided.
The utility model is to realize by the following technical solutions above-mentioned purpose:
A kind of LED fluorescent tube of high efficiency and heat radiation, comprise lamp housing, aluminium base, be arranged at the LED integrated chip circuit block in the lamp housing, terminals and the side cover of encapsulation lamp housing by aluminium base, it is characterized in that: be symmetry shape in the lamp housing and be provided with slot, aluminium base is actively plugged in the lamp housing by slot, the upper surface of aluminium base is provided with a plurality of radiation tooths, is arranged at intervals with a plurality of louvres on lamp housing corresponding to radiation tooth.
The utility model beneficial effect compared with prior art is:
The utility model is simple in structure, aluminium base is actively plugged in by slot is convenient to assembling and maintenance in the lamp housing, a plurality of louvres that a plurality of radiation tooths by the setting of aluminium base upper surface have increased area of dissipation, arranged by interval on the lamp housing simultaneously, can be with the heat Quick diffusing of the generations such as lamp pearl, avoided existing being transmitted on the aluminium base by heat-conducting silicone grease to dispel the heat, after long-time, heat-conducting silicone grease can become dry, the problem that the heat that causes light emitting diode to produce can't in time conduct.Effectively raise radiating effect.
Description of drawings
Fig. 1 is the structural representation of utility model lamp housing;
Fig. 2 is the assembling schematic diagram of utility model lamp housing and aluminium base.
Among the figure: 1, lamp housing, 2, aluminium base, 3, slot, 4, radiation tooth, 5, louvre.
The specific embodiment
The LED fluorescent tube of this high efficiency and heat radiation comprises lamp housing 1, aluminium base 2, is arranged at the LED integrated chip circuit block in the lamp housing 1, terminals and the side cover of encapsulation lamp housing 2 by aluminium base 2.Be symmetry shape in the lamp housing 1 and be provided with slot 3, aluminium base 2 is actively plugged in the lamp housing 1 by slot 3, and the upper surface of aluminium base 1 is provided with a plurality of radiation tooths 4, is arranged at intervals with a plurality of louvres 5 on the lamp housing 1 of radiation tooth 4 correspondences.
The lamp housing 1 of utility model adopts the PC material to make, aluminium base 2 is actively plugged in the lamp housing 1 by slot 3, a plurality of radiation tooths 4 that aluminium base 2 arranges by its upper surface, effectively increased area of dissipation, the heat that aluminium base 2 distributes in the course of work is able to Quick diffusing by the louvre 5 on the lamp housing 1.Avoided existing being transmitted on the aluminium base 2 by heat-conducting silicone grease to dispel the heat, long-time after, heat-conducting silicone grease can become dry, the problem that the heat that causes light emitting diode to produce can't in time conduct.Effectively raise radiating effect.
