Abstract

The utility model provides an LED fluorescent tube, which comprises a PCB, a radiator, an outer cover and two core plugs, and is characterized in that a plurality of lamp beads are welded on the PCB, locked on the planar PCB installation baseplate of the radiator, and limited by the PCB positioning bayonets arranged on the two core plugs; the radiator adopts a semi-arc arched structure, a power supply with a female terminal is mounted and connected in the semi arc, the planar PCB installation baseplate is arranged at the bottom of the arch, and a positioning screw hole and an outer cover bayonet with an opening facing outwards are arranged on the bottom edge of the arch; the outer cover adopts an arched structure with non-uniform wall thickness and is clamped on the outer cover bayonet of the radiator through clamping pieces on the edge; the two core plugs are symmetrically nested at the two end parts of the radiator and fixed on the positioning screw hole of the radiator through half-round head screws, a guide slot is formed on the periphery of each core plug, and a breathing hole is formed in the semi-arc direction of the radiator. With simple structure, the utility model makes the lightening of the fluorescent tube uniform and soft, and greatly prolongs the service life of the fluorescent tube at the same time.

Description

The Novel LED fluorescent lamp pipe

Technical field

The utility model relates to illuminations, is specially a kind of Novel LED fluorescent lamp pipe.

Background technology

LED was come out the sixties in 20th century, fields such as experience indicator lamp, signal lamp, display screen, Landscape Lighting, along with people's deepening continuously to semiconductive luminescent materials research, the development and application of the continuous progress of LED manufacturing process and new material (element nitride crystal and fluorescent material), LED is declined to a great extent aspect cost having obtained remarkable lifting aspect the product luminous efficiency.Compare other conventional light source, LED itself has low power consumption, high directivity, long-life, tunable optical, volume is little and characteristic such as high color rendering, and it is inevitable to make that LED has become as the illumination level product.

LED fluorescent tube in the market generally all is circular transparent PC outer cover or thickening outer cover or double-deck outer cover, and the radiator of outer watchband wing needs direction of rotation could locate the plug of assembling finished product, power supply and PCB and forms.Such product directly causes heat dispersion bad, dazzling, and light extraction efficiency is low, and life of product is short, and production efficiency is low.

The utility model content

The technical problem that the utility model solved is to provide a kind of Novel LED fluorescent lamp pipe, to solve the shortcoming in the above-mentioned background technology.

The technical problem that the utility model solved realizes by the following technical solutions:

The Novel LED fluorescent lamp pipe comprises pcb board, radiator, outer cover and plug, and some lamp pearls of welding and the plane P CB that is locked in radiator install base plate on the described PCB plate, and the PCB limited bayonet that is provided with on the plug can play position-limiting action.

Described radiator is half arc arch shape structure, and the power supply that is connected with female terminal is installed in half arc, the inside and outside two-sided design fin radiating structure of arch, and arch is provided with plane P CB base plate is installed at the end, and the arch feather edge is provided with set screw hole and opening direction outer cover bayonet socket outwardly.The radiator of this structure under equal conditions can increase the area of dissipation of product, just is the equal of the temperature rise that has reduced product, has improved life of product.

Described outer cover utilizes the shackle member at edge to be installed on the outer cover bayonet socket of radiator, is domes, adopts inhomogeneous wall thickness, and the place is thinner at vault.This structure has increased LED to the space length between the outer cover, has reduced the condition of the dazzling generation of LED, makes light softer.

Described plug has two, symmetry is enclosed within the both ends of radiator, and is fixed on half-round head screw on the set screw hole of radiator, and the plug periphery is provided with guide slot, can guarantee the sensing of fluorescent tube itself, make the installation direction of product become vertical relation with the light direction of fluorescent tube; Plug is offered passage in half arc direction of radiator, because two plugs adopt symmetry to install, so passage is on the same axis, this structure is beneficial to the inner air circulation, strengthen heat dispersion, plug respectively is provided with two pieces of conductive copper pins in addition, links to each other with the female terminal of power supply.

Beneficial effect: the utility model is simple in structure, makes fluorescent light emitting tube more evenly soft, has prolonged the life-span of fluorescent tube simultaneously greatly.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

Referring to Fig. 1, Fig. 2, Fig. 3, the Novel LED fluorescent lamp pipe comprises pcb board 3, radiator 2, outer cover 1 and plug 4, some lamp pearls of welding and the plane P CB that is locked in radiator 2 install on the base plate 8 on the described pcb board 3, and the PCB limited bayonet 11 that is provided with on the plug 4 can play position-limiting action.

Described radiator 2 is half arc arch shape structure, and the power supply 5 that is connected with female terminal 6 is installed in half arc, the inside and outside two-sided design fin radiating structure of arch, and the edge is provided with plane P CB base plate 8 and opening outer cover bayonet socket 9 outwardly is installed, and set screw hole 10 is set.The radiator of this structure under equal conditions can increase the area of dissipation of product, just is the equal of the temperature rise that has reduced product, has improved life of product.

Described outer cover 1 utilizes the shackle member 7 at edge to be installed on the outer cover bayonet socket 9 of radiator 2, is the domes of inhomogeneous wall thickness, and the place is thinner at vault.This structure has increased LED to the space length between the outer cover, has reduced the condition of the dazzling generation of LED, makes light softer.

Described plug 4 has two, symmetry is enclosed within the both ends of radiator 2, and be fixed on the set screw hole 10 of radiator 2 with the half-round head screw of 4 M2.5, plug 4 peripheries are provided with guide slot 12, can guarantee the sensing of fluorescent tube itself, make the installation direction of product become vertical relation with the light direction of fluorescent tube; Plug 4 is offered passage 13 in half arc direction of radiator 2, because two plugs 4 adopt symmetry to install, so passage 13 is on the same axis, this structure is beneficial to the inner air circulation, strengthen heat dispersion, plug 4 respectively is provided with two pieces of conductive copper pins 14 in addition, links to each other with the female terminal 6 of power supply 5.

More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
