Abstract
The invention relates to a light-emitting diode (LED) curve-face light guide lamp which comprises a curve-face light guide plate, an LED lamp strip and a radiating strip. The section of the curve-face light guide plate is a part of a ring, the LED lamp strip is arranged on the vertical section of the curve-face light guide plate, the light-emitting face of the LED faces the section and is in contact connection with the vertical section, the back of the LED is connected with an aluminum substrate lamp strip to form the LED lamp strip, the LED lamp strip is inserted into an aluminum substrate connection groove of a radiating fin, and an aluminum substrate of the lamp strip is in contact connection with the radiating fin. Lighting is conducted through scattering of light reflection points of the whole curve-face light guide plate, the light-emitting area is large, and the light is even. The curve-face light guide plate is arc, so that the lamp saves space obviously compared with a flat light guide lamp with identical area.
Description
Technical field
The present invention relates to a kind of LED lamp, particularly relate to a kind of LED curved surface light-guiding lamp.
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, but the array light source substantially being formed by a lot of LED lamp pearls, directly produce lighting source by each 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 discomfort to user's eyes, and this fluorescent tube needs a large amount of LED lamp pearls be arranged on lamp plate, just to reach the brightness needing, cost of manufacture is high; Also have on the market a kind of LED flat lamp, this lamp is to establish illuminator in dull and stereotyped side, and the light guiding points on plane catheter plate makes light scattering become a kind of lamp of area source.The light that this flat lamp is irradiated is evenly soft, but this flat lamp is owing to being by dull and stereotyped leaded light, 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 a little less than, can not resemble fluorescent tube and allow and around evenly illuminate, therefore the actual limitation that uses is very large; Also do not find at present this series products as for LED curved surface light-guiding lamp.
Summary of the invention
Object of the present invention is exactly the defect existing for prior art, and a kind of LED curved surface light-guiding lamp is provided.
For achieving the above object, the present invention adopts following technical scheme:
A kind of LED curved surface light-guiding lamp, comprise: curved surface LGP, LED lamp bar, heat sink strip, the part that described its cross section of curved surface LGP is annular, on the longitudinal section of curved surface LGP, be respectively equipped with LED lamp bar, the light-emitting area of LED is towards cross section, and is connected with longitudinal section contact, and the back side of LED connects aluminium base lamp bar formation LED lamp bar, the aluminium base link slot of LED lamp bar and fin is pegged graft, and the aluminium base of lamp bar is connected with fin contact; Described longitudinal section refers to that the elongated surfaces in cross section is through the axial line of curved surface LGP, and overlap with axial line, the interior sidewall surface of curved surface LGP is provided with reflective spot and reflector layer, and the outer side surface of curved surface LGP is provided with diffusion layer, and reflector layer is connected with the contact of curved surface LGP with diffusion layer.
Described curved surface LGP is transparent pipe, and the interior outside of its wall is shiny surface.

The heat sink strip connecting on two faces of described longitudinal section can divide and is arranged, and point heat sink strip being arranged is provided with slot therebetween, and heat sink strip is by pegging graft and interconnect with slot.
Described curved surface LGP is provided with LED power supply driver.
The two ends of described curved surface LGP are provided with decorative panel.
Described curved surface LGP can composition connected with each other one group, described and connect and refer to that wherein two outer side edges contact of two curved surface LGP longitudinal sections connects, heat sink strip in two outer side edges contact connections is connected as a single entity, and between all heat sink strips, is fixedly connected with by connecting plate.
In the inner chambers of described curved surface LGP, be provided with LED driver, external power supply is electrically connected with LED lamp bar by LED driver.
Beneficial effect of the present invention: due to luminous be luminous by the reflective spot scattering of whole curved surface LGP, not only light-emitting area is large, light is even, and curved surface LGP is owing to being arc, save space than the dull and stereotyped light-guiding lamp of same homalographic significantly, and can be to the side-irradiation of LGP, whole irradiation ambient light is even; Owing to being whole curved surface LGP leaded light, light is softer, and shadow surface is larger, and not only brightness is high, and more energy-conservation than traditional fluorescent lamp, more universal use; Due to single LED lamp pearl being just set in the longitudinal section of curved surface LGP, obviously reduce than traditional LED fluorescent tube by the quantity of lamp pearl, therefore cost of manufacture significantly reduces.
