Abstract

An LED (light-emitting diode) fluorescent lamp comprises a radiating aluminum groove, a PC (poly carbonate) lampshade, a circuit board and an LED lamp disposed on the circuit board, and is characterized by further comprising fasteners for fixing the LED fluorescent lamp, a connection terminal and end caps. The connection terminal is used for connecting wires and disposed in the radiating aluminum groove, the end caps with through hole caps are embedded into two ends of the radiating aluminum groove, the cross section of the radiating aluminum groove is an up-down open support, the circuit board is disposed in a circuit board groove which is provided with a bayonet in the middle and positioned at an upper opening of the radiating aluminum groove, a hook is arranged below the circuit board groove. The LED fluorescent lamp has the advantages that a lower opening space of the radiating aluminum groove is large and capable of accommodating the connection terminal and hiding needless power lines after installation, air ventilation is benefitted, radiating of the LED fluorescent lamp is quickened, and service life of the LED fluorescent lamp is prolonged.

Description

A kind of LED fluorescent lamp

Technical field

The technology of the present invention relates to the fluorescent lamp in a kind of lighting apparatus, especially relates to a kind of LED fluorescent lamp of structure.

Background technology

Along with the development of LED technology, LED uses lighting field and obtains broad development, and the LED fluorescent lamp also is that it one of is used.It adopts LED as light emitting source, has environmental protection and energy saving, and luminous efficiency height, long advantage of life-span are usually used in room lightings such as family, market, school.Traditional fluorescent lamp or common fluorescent lamp on the market because design or technological reason, can not be given full play to the advantage of LED, often have following problem:

1 weak heat-dissipating, the radiator of the LED fluorescent lamp on the existing market is generally enclosed aluminum pipe or board-like aluminium sheet, and the bad LED light decay phenomenon that causes of dispelling the heat is serious, influences the LED life-span.

2 lighting angles are low, and lampshade often is semi-circular design, and the edge is often with the dark space.

3 lampshades easily come off, and the lampshade edge is horizontal, and the cross section designs for semicircle, and during pressurized, tension force causes lampshade to be the expansion type distortion to external diffusion, easily and the aluminium groove come off.

4 efficiencies of construction are low, and common fluorescent lamp internal connection line adopts naked copper to connect and the mode of wrapping electrician's adhesive plaster or employing Wire crimping cap realizes.Each connection jaws all needs manually to carry out the operation of a plurality of steps, and efficiency of construction is low.

5 cost height as described in 4, expend adhesive plaster and Wire crimping cap and cost of labor, the cost height.

6 cascades are installed inharmonious attractive in appearance, and common fluorescent lamp end cap is not reserved through hole, or there is bossing the end cap side, when cascade is used, the space are arranged between the light fixture, and are when light fixture is lighted, " deceive " in space and the formation sharp contrast of " in vain " of light fixture, inharmonious and attractive in appearance.

Summary of the invention

In view of the existing problem in front, the invention provides a kind of LED fluorescent lamp, particularly have rapid heat dissipation, can a plurality of fluorescent lamp cascades, LED fluorescent lamp attractive in appearance firm, easy for installation.

A kind of LED fluorescent lamp, it comprises heat radiation aluminium groove, PC lampshade, circuit board, places the LED lamp of circuit board, the buckle that also comprises fixed L ED fluorescent lamp, be embedded in the end cap of heat radiation aluminium groove two ends band through hole lid, described heat radiation aluminium slot cross-section is the support of upper and lower opening, described circuit board is arranged at the centre circuit board slot with bayonet of heat radiation aluminium groove upper shed, and there is hook described circuit board slot below.

Preferably, described heat radiation aluminium groove upper shed two edges are PC lampshade bayonet socket, and described lampshade bayonet socket is the angle that makes progress, and described heat radiation aluminium groove under shed shape is as " clock " cross section, and described heat radiation aluminium groove under shed two edges are for being the outside rectangle edge that protrudes.

Preferably, the cross section radian of described PC lampshade is greater than 180 degree.

Preferably, described through hole lid is split with end cap, and can take off and buckle.

Preferably, cross sectional shape when described end cap shape and PC lampshade are stuck in heat radiation aluminium groove coincide, the forward part of described end cap is containing end cap hypotenuse, described end cap top is covered in PC lampshade outside, the PC lampshade places end cap hypotenuse top, and described end cap lower part is embedded in the heat radiation aluminium groove under shed, and there is chimb rear end, end cap lower part, chimb size is identical with the outside of heat radiation aluminium groove, in the middle of the described end cap end cap breach is arranged and is stuck in the PC lampshade and dispels the heat between the aluminium groove.

Preferably, described hook is connected with ground wire by binding post.

Its beneficial effect is, the under shed space of heat radiation aluminium groove is bigger, can put binding post, and hide the unnecessary power line in back is installed, the circulation of useful wherein air, accelerated the heat radiation of LED fluorescent lamp lamp, the life-span of LED fluorescent lamp is prolonged, the cross section radian of PC lampshade is greater than 180 degree, light-emitting area than the LED fluorescent lamp on the existing market increases greatly, the upwards angle of the PC lampshade bayonet socket of heat radiation aluminium groove, when making circular arc in work progress, be subjected to the extruding of external force greater than the 180 PC lampshades of spending, extruding force can be diffused on the whole circular arc of PC lampshade, firm so greatly PC lampshade, and reduced destruction, the hook of heat radiation aluminium groove is connected with binding post, being connected with ground wire simultaneously can be anticreep, guarantee tightens security, the LED fluorescent lamp uses snap fit in installed surface, not only saved the set-up time, also made things convenient for the maintenance of LED fluorescent lamp, binding post and through hole lid in the heat radiation aluminium groove can be when cascade LED fluorescent lamps, do not destroy under the existing environment simple, fast, install cheaply, and need not be gapped between the light fixture.
