Abstract
The utility model discloses an LED light tube which comprises a tube body formed from mutually buckling a radiator and a light cover, and both ends of the tube body are provided with contact pins; the side surface of radiator positioned in the tube body is provided with an aluminium base plate; the aluminium base plate is provided with an LED; and the side surface of the radiator positioned outside the tube body is provided with a plurality of vertical bending radiating ribs. The radiator of the LED light tube provided with the radiator is provided with the plurality of vertical bending radiating ribs, enlarges the radiating area, enhances the radiating effect, and prolongs the service life.
Description
Technical field
The utility model relates to a kind of illuminations, relates in particular to a kind of LED fluorescent tube that has radiator.
Background technology
At present, adopt be widely used every aspect in industrial production or the life of the lighting engineering of light emitting diode (LED) fluorescent tube.Existing LED fluorescent tube generally comprises the Transparent lamp tube of both ends open, is provided with a plurality of LED in the fluorescent tube and is inserted in the interior circuit board of fluorescent tube, and Transparent lamp tube is generally made by lucite tube or PC pipe.
According to statistics, existing LE fluorescent tube is regardless of its profile, nearly having only, 15% electric energy is utilized, remaining 85% all discharges with the form of heat, therefore, along with the increase LED light fixture of brightness can produce the problem of heating in use, thereby influence the LED luminescent effect, seriously decay causes its life-span to shorten greatly under heating effect.
Chinese patent 200720141004.7 discloses a kind of LED lamp tube structure, and it mainly comprises: a lamp housing, be equipped with light-emittingdiode LED on it, and both sides are provided with tube plug, and; One metal fin is located at the in addition side of lamp housing, pastes mutually with light-emittingdiode LED root and touches.
The LED fluorescent tube radiating effect of this patent disclosure is not good enough, causes service life shorter.
Summary of the invention
The utility model provides the LED fluorescent tube that has radiator of a kind of good heat dissipation effect, long service life.
A kind of LED fluorescent tube, comprise by radiator and lampshade fastening the body of forming mutually, the body two ends are provided with contact pin, and the side that radiator is positioned at body is provided with aluminium base, aluminium base is provided with LED, and radiator is positioned at the radiating ribs that the outer side of body is provided with some bendings.
The utility model provides a kind of LED fluorescent tube that has radiator, and its radiator is provided with crooked radiating ribs, has enlarged area of dissipation, has improved radiating effect, has prolonged service life.
Description of drawings
Fig. 1 has the LED fluorescent tube outside drawing of radiator for the utility model;
Fig. 2 is a LED fluorescent tube A-A profile shown in Figure 1;
Fig. 3 is a LED fluorescent tube B-B profile shown in Figure 1.
The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, a kind of LED fluorescent tube that has radiator, comprise by radiator 2 and lampshade 3 and fasten the body of forming 1, the side that radiator 2 is positioned at body 1 is provided with aluminium base 9, aluminium base 9 is provided with LED10, and radiator 2 is positioned at the radiating ribs 4 that body 1 outer side is provided with some bendings.
In order to prevent the power supply reversal connection, be welded with bridge heap 8 on the aluminium base 9.
The two ends of body 1 are with adapter of plastic 6, adapter of plastic 6 inside are provided with stator, stator is provided with first fixed bar 11, first fixed bar 11 inserts in first fixing hole 13 that is surrounded by radiating ribs 4, thereby realize the location, the center, two ends of radiator 2 is provided with the centre bore 12 that is surrounded by radiating ribs 4, and nut passes stator and pierces in the centre bore 12, thereby fixed plastics joint 6 is connected on the radiator 2.
Be with lamp holder 7 on adapter of plastic 6 outer walls, lamp holder 7 is provided with contact pin 5.
The side that radiator 2 is installed aluminium base 8 is provided with the groove that matches with aluminium base 8, and aluminium base 8 places in the groove, and the thickness of aluminium base 8 is consistent with the height of groove, good looking appearance.
