Abstract

An LED circular lamp tube free of screwed connection comprises a semi-circular aluminum tube, a semi-circular plastic tube, and a plastic cylindrical cover. A square hole with a size of 10 * 5 mm is arranged in the left part of the semi-circular plastic tube at a place 15 mm away from the tube edge, and another square hole with a size of 10 * 5 mm is arranged in the right part of the semi-circular plastic tube at a place 15 mm away from the tube edge. An inverted triangle-shaped hook with a size of 8 * 13 mm is arranged in the left part of the plastic cylindrical cover at a place 15 mm away from the edge, and another inverted triangle-shaped hook with a size of 8 * 13 mm is arranged in the right part of the plastic cylindrical cover at a place 15 mm away from the edge. The central part of the plastic cylindrical cover is provided with a small circular hole, the diameter of which is 3 mm. An aluminum-plastic tube is formed by sleeve the plastic tube on the aluminum tube. The left and right parts of the aluminum-plastic tube are buckled by the plastic cylindrical cover. The inverted triangle-shaped hooks in the interior of the cover enter into the square holes of the semi-circular tube so that the cover is prevented from dropping outwards. The LED circular lamp tube is advantaged by security, low cost, low power consumption, and long service life.

Description

A kind of LED round lamp tube of exempting from screw connection

Technical field

The utility model relates to a kind of connected mode of fluorescent tube, particularly relates to a kind of LED round lamp tube that screw connects of exempting from

Background technology

At present, semiconductor light emitting diode (LED) be after incandescent lamp and fluorescent lamp the 4th generation semiconductor illuminating light source.Though existing, adopt, brightness is low, is widely used still and is difficult to.Also someone adopts the LED illuminating lamp of special-purpose driver module, due to high cost, makes LED illumination enter into family and has difficulty in taking a step.And add resistance ballast mode with simple electric capacity, though can reduce costs, because it is subject to surge current impact, damage, and have shortcoming unstable, that power consumption efficiency is not high, therefore the product that market has practical value there are no such is sold.

LED fluorescent tube, dazzle is little, radiationless, not containing mercury element, in production and use, does not all send harmful substance, is conducive to environmental protection, and energy-conservation, durable.Can automatically control its luminous intensity according to the bright degree of environment, some experts even predict that both at home and abroad, LED Intelligent lighting lamp will be one of most active high-tech product of 21 century maximum, and it is all being significant aspect economic competition and national security.

Summary of the invention:

For overcoming the deficiencies in the prior art, the utility model comprises semicircle aluminum pipe, semicircle plastic tube, plastic cylinder shape cover.

There is an one-time formed 10*5mm square hole on the described semicircle plastic tube left side from tube edge 15mm place, there is an one-time formed 10*5mm square hole on the right from tube edge 55mm place.

The left side of described plastic cylinder shape cover, there is a 8*13mm inverted triangle hook at 15mm place, isolated edge place, on cover, there are two metal circular pins, be outside one of the junction of voltage that provides to round tube, for being contained in the plastic cylinder shape cover on pipe the right, there is a 8*13mm inverted triangle hook at 55mm place, isolated edge place, on cover, there are two metal circular pins, be that outside provides one of junction of voltage to round tube, there is the small sircle hole that a diameter is 3mm the middle part of cover

Described plastic pipe sleeve, on aluminum pipe, forms an aluminium-plastic pipe, and the left and right of aluminium-plastic pipe fastens with plastic cylinder shape cover, and the inverted triangle hook of cover inside enters in the square hole of semi-circular tube, can prevent that cover from outwards coming off.

The beneficial effects of the utility model: realize at lower cost the useful product that LED illumination enters into family, obvious energy conservation (can economize on electricity nearly 80%), environmental protection is (not mercurous and plumbous, waste product can not endanger environment structure), belong to policy support scope, have good economic benefits and social benefit, market prospects are superior, its cost is low, power saving, safety, long service life, becomes family, office and requires the first-selected product in general place.

The specific embodiment

With reference to Fig. 1-Fig. 7, can regard as, the utility model comprises: semicircle aluminum pipe, semicircle plastic tube, there is an one-time formed 10*5mm square hole on the plastic tube left side from tube edge 15mm place, there is an one-time formed 10*5mm square hole on the right from tube edge 55mm place, plastic cylinder shape cover and the left side, there is a 8*13mm inverted triangle hook at 15mm place, isolated edge place, there is a 8*13mm inverted triangle hook at 55mm place, isolated edge place, the right, on cover, there are two metal circular pins, it is outside one of the junction of voltage that provides to round tube, there is the small sircle hole that a diameter is 3mm the middle part of cover, when plastic pipe sleeve is on aluminum pipe, form an aluminium-plastic pipe, a left side for aluminium-plastic pipe, rightly with plastic cylinder shape cover, fasten, the inverted triangle hook of cover inside enters in the square hole of semi-circular tube, can prevent that cover from outwards coming off.

Claims

1. exempt from the LED round lamp tube that screw connects for one kind, comprise semicircle aluminum pipe, semicircle plastic tube, plastic cylinder shape cover, it is characterized in that: described semicircle plastic tube, its 15mm place, distance edge, left side is designed with an one-time formed 10*5mm square hole, and its right side is designed with an one-time formed 10*5mm square hole apart from 55mm place, edge; There is a 8*13mm inverted triangle hook at described 15mm place, distance edge, plastic cylinder shape cover left side, there is a 8*13mm inverted triangle hook on right side apart from 55mm place, edge, there is the small sircle hole that a diameter is 3mm the middle part of plastic cylinder shape cover, when plastic pipe sleeve is on aluminum pipe, form an aluminium-plastic pipe, the left and right of aluminium-plastic pipe fastens with plastic cylinder shape cover, and the inverted triangle hook of cover inside enters in the square hole of semi-circular tube, can prevent that cover from outwards coming off.
