In addition, the lamp tube wall is arc-shaped, a space is obviously saved compared with a plane lamp with the same area, and the light is irradiated toward the side of the lamp tube.

Description

A kind of LED leaded light fluorescent tube

Technical field

The present invention relates to LED fluorescent tube, particularly relate to a kind of LED leaded light fluorescent tube.

Background technology

LED lamp is due to the energy-conservation favor that is more and more subject to people, there are being on the market various LED lamps, also there is LED fluorescent tube, but this LED fluorescent tube is a lot of lED lamp pearl compositions, directly produce lighting source by lED lamp pearl, because lED lamp pearl is spot light, the spot light area of each part is very little and very bright, therefore very dazzling, bring serious discomfort to user's eyes, although the surface of some LED fluorescent tube fluorescent tube has put one deck astigmatism plate, but the light that sees through astigmatism plate is still inhomogeneous, because the LED lamp pearl that is fluorescent tube inside is luminous, there is no the luminous sensation of tube wall, light is even not, and a large amount of LED lamp pearl of this fluorescent tube needs is arranged on the brightness that just can reach needs on lamp plate, cost of manufacture is high, also have on the market LED flat lamp, this lamp is to utilize flat light guide plate to establish illuminator in dull and stereotyped side, makes LGP light scattering become a kind of lamp of area source through light guiding points.This flat lamp leaded light is evenly soft, but this flat lamp is owing to being by flat-plate luminous, be generally little flat lamp, use as ornament lamp, as the flat lamp of general lighting, because developed area is too large, not only inconvenience is installed, and flat board can only irradiate dull and stereotyped irradiation area above, the light of its side is very weak, can not resemble fluorescent tube and allow and around evenly illuminate, and therefore the actual limitation that uses is very large; Lamp as for LED leaded light fluorescent tube is not also found this series products at present.

Summary of the invention

Object of the present invention is exactly the defect existing for prior art, and a kind of LED leaded light fluorescent tube is provided.

For achieving the above object, the present invention adopts following technical scheme:

A kind of LED leaded light fluorescent tube, comprise: light pipe, LED lamp plate, radiating block, its cross section of described light pipe is a part for annular or annular, cross section (5) or longitudinal section (5 ') of light pipe are provided with LED lamp plate, the light-emitting area of LED is towards cross section, and be connected with cross section or longitudinal section contact, the back side of LED connects aluminium base, and aluminium base is connected with the aluminium base link slot contact of fin; Described longitudinal section refers to that the elongated surfaces in cross section is through the axial line of light pipe, and overlap with axial line, the interior sidewall surface of light pipe is provided with reflective spot and reflector layer, and the outer side surface of light pipe is provided with sheen layer, and reflector layer is connected with light pipe contact with sheen layer.

Described light pipe is transparent pipe, and the interior outside of its wall is shiny surface.

Described reflector layer and sheen layer are flexible plastic plate or plastic foil, be connected adopt contact to connect or bonding with curved surface LGP.

Described reflector layer and sheen layer are sprayed coating.

Its cross section of described light pipe is annular, and contacting with circular ring section the LED lamp plate being connected is annular.

The part that its cross section of described light pipe is annular, its longitudinal section is two faces, has at least a longitudinal section to be provided with LED lamp plate, the LED lamp plate on longitudinal section is strip lamp plate.

Described radiating block is provided with the link slot with light pipe, and light pipe and link slot are pegged graft.

Its cross section of described light pipe is annular, and the radiating block being connected with circular ring section is provided with the insertion pipe with light pipe, and light pipe and insertion pipe (8) are pegged graft.

In the pipe of described light pipe, be provided with LED driver, external power supply is electrically connected with LED lamp plate by LED driver.

The radiating block (1 ') connecting on two faces of described longitudinal section can be connected as a single entity.

Beneficial effect of the present invention: due to luminous be by being luminous by the reflective spot scattering of whole fluorescent tube, not only light-emitting area is large, light is even, and lamp tube wall is owing to being arc, save space than the flat lamp of same homalographic significantly, and can be to the side-irradiation of fluorescent tube, whole irradiation ambient light is even; Owing to being whole lamp luminescence, more easily adapt to for making to be accustomed to the use of the general user of traditional fluorescent tube, due to more energy-conservation than traditional fluorescent lamp, the better effects if of light, more universal use; Owing to just in cross section and the middle section of fluorescent tube, single LED lamp pearl being set, obviously reduce than traditional LED fluorescent tube by the quantity of lamp pearl, therefore cost of manufacture significantly reduces.
