Description

A kind of LED fluorescent tube

Technical field

The utility model relates to the normal lighting field, refers to a kind of LED of using fluorescent tube especially.

Technical background

Along with development of science and technology, people's living standard is also progressively improving, and light has important role to mankind's activity, and normal lighting also is subject to people's attention all the more.

With regard to the LED fluorescent lamp, as light source, the LED advantage is embodied in three aspects: energy-saving and environmental protection and long-life.It is luminous that LED does not rely on the filament heating, and energy conversion efficiency is very high, can reach the energy consumption of incandescent lamp 10% in theory, compares fluorescent lamp, and LED also can reach the energy-saving effect more than 70%.China's Green Lighting Project promotes project office to do an ad hoc survey, replaces whole incandescent lamps or part replaces fluorescent lamp with LED, saves 2/3 electric consumption on lighting, and this has crucial meaning undoubtedly concerning the very nervous China of the energy.Aspect environmental protection, use the LED replace fluorescent lamps, avoid fluorescent tube to break and overflowed the secondary pollution of mercury.

But existing LED fluorescent lamp normally is directly installed on control circuit in the pipe space of plastic material or is installed in metab and lampshade forms in the totally enclosed space, and the control element of LED lamp is set under pcb board, the LED lamp is unreasonable less than heat radiation or heat dissipation design, to such an extent as to the heat that distributes during the work of LED lamp can't effectively discharge, thereby reduce the service life and the security of LED lamp greatly.Moreover the lampshade of existing LED lamp adopts materials such as conventional material glass, acryl to make more, and glass lamp shade is frangible, poor stability; The acryl Transparent lamp shade can produce dazzle, and the people dare not be looked at straight; Acryl frosted lampshade produces light and seriously blocks, and light efficiency reduces significantly.

In view of this utility model creator and gives research innovation, discloses a kind of LED fluorescent tube shown in the utility model.

The utility model content

The utility model purpose aims to provide a kind of LED fluorescent tube, this LED fluorescent tube comprises: the PC diffuser, this PC diffuser adopts advanced PC diffuse reflection material to make with extra care and forms, its cutting plane is the great circle arcuation, respectively there is the card end of a horizontal curvature at the two ends of cutting plane, two checkpost ends are relatively to stretching out, and a circular arc projection is all arranged inwards, form the bayonet socket of a uniqueness; The LED bearing, this LED bearing is the aluminum structure moulding, its cutting plane outside is the sector wind trellis, the groove screens of its both sides external and the bayonet socket of PC diffuser are closely pegged graft, inner bottom surface is the plane, the parts mounting bracket of a both sides irregular step structure design formation special construction, and circular-arc two tips, upper end as crescent moon, this LED bearing and PC diffuser form an elongated cylindrical housing; Pcb board is equipped with the staggered led chip of several rules on this pcb board, it is installed on the bottom surface of LED bearing, and contacts fully with the bottom surface; Power supply, this power supply places the two ends of fluorescent tube; Plug, this plug are the plastic cement cylindrical shell, and plastic cement cylindrical shell upper surface has two protruding metal contacts.

A kind of LED fluorescent tube that the utility model disclosed is to have following advantage and feature, and shows the usability of novelty progressive of the present utility model and industry:

1, the LED bearing is " sector wind trellis " aluminum structure moulding, unique radiator structure, add that pcb board contacts fully with the bottom surface, its heat radiation contact-making surface maximizes the use, the heat that led light source work the time is sent can be more direct conducts in air by fan-shaped, and the arrangement moulding of style simultaneously is more conducive to the circulation of air, and form effective cross-ventilation, reach good thermolysis; The various performances that this unique design helps the LED fluorescent lamp obtain stable performance, more can guarantee the service life of light source.

2, the PC diffuser adopts advanced person's refining the forming of PC diffuse reflection material, and high light transmittance is not only arranged, radiationless light source, and eliminated " dazzle " influence to human eye, accomplished real environmental protection; Unique bayonet socket design between lampshade and the aluminium frame had simultaneously both prevented that the people from being the destruction of dismounting, and throw off naturally on the two sides when preventing the long-time temperature distortion of lampshade again, and adding upper plug head is plastic cement material, makes the use of LED fluorescent tube have more security.

Desirable entity of the present utility model can and respectively illustrate accompanying drawing by the following description, and be able to distinct.
