Abstract
The utility model relates to a light emitting diode (LED) curved surface light guide lamp which comprises a curved surface light guide plate, LED lamp bars and heat dissipation bars, wherein the section of the curved surface light guide plate is a part of an annulus, the LED lamp bars are arranged on the longitudinal sections of the curved surface light guide plate, light-emitting surfaces of LEDs face the section and are in contact connection with the longitudinal sections, aluminum base plate lamp bars are connected with the back sides of the LEDs to form the LED lamp bars, the LED lamp bars are connected with aluminum base plate connecting grooves of a heat dissipation piece in an inserted mode, and aluminum base plates of the lamp bars are in contact connection with the heat dissipation piece. Due to the fact that reflection points of the whole curved surface light guide tube are used for emitting light in a scattering mode, the light emitting area is large, and light is even. Due to the fact that the curved surface light guide tube is arc-shaped, occupied space is much smaller than a plane lamp with the same area.
Description
Technical field
The utility model relates to a kind of LED lamp, particularly relates to a kind of LED curved surface light-guiding lamp.
Background technology
The LED lamp is due to the energy-conservation favor that more and more is subject to people, various LED lamps are being arranged on the market, but the array light source that is substantially formed by a lot of LED lamp pearls, directly produce lighting source by each LED lamp pearl, because LED lamp pearl is spot light, each local spot light area is very little and very bright, therefore very dazzling, bring discomfort for user's eyes, and this fluorescent tube needs a large amount of LED lamp pearls be arranged on just to reach the brightness that needs on lamp plate, cost of manufacture is high; Also have on the market a kind of LED flat lamp, this lamp is to establish illuminator in the side of flat board, and the light guiding points on the catheter plate of plane makes light scattering become a kind of lamp of area source.The light of this flat lamp irradiation 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, because developed area is too large, not only inconvenience is installed as the flat lamp of general lighting, and the dull and stereotyped irradiation area that can only shine dull and stereotyped front, the light of its side a little less than, can not resemble to allow fluorescent tube and evenly illuminate on every side, therefore the actual limitation of using is very large; Also do not find at present this series products as for LED curved surface light-guiding lamp.
Summary of the invention
The purpose of this utility model is exactly the defective that exists for prior art, and a kind of LED curved surface light-guiding lamp is provided.
For achieving the above object, the utility model adopts following technical scheme:
A kind of LED curved surface light-guiding lamp, comprise: curved surface LGP, LED lamp bar, heat sink strip, its cross section of described curved surface LGP is the part of annular, be respectively equipped with LED lamp bar on the longitudinal section of curved surface LGP, the light-emitting area of LED is towards the cross section, and is connected with the 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 the 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.
Described reflector layer and diffusion layer are flexible plastic plate or plastic foil, are connected with the curved surface LGP to adopt contact to connect or bonding.
Described reflector layer and diffusion layer are sprayed coating.
Described heat sink strip is provided with the link slot with the curved surface LGP, and curved surface LGP and link slot are pegged graft.
The heat sink strip that connects on two faces of described longitudinal section can divide and is arranged, and the heat sink strip that minute is arranged is provided with slot therebetween, and heat sink strip interconnects by pegging graft with slot.
Described curved surface LGP is provided with the 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 wherein two the outer side edges contacts that refer to two curved surface LGP longitudinal sections and connect, the heat sink strip that the contact of two outer side edges connects is connected as a single entity, and is fixedly connected with by connecting plate between all heat sink strips.
Be provided with LED driver in the inner chambers of described curved surface LGP, external power supply is electrically connected to LED lamp bar by LED driver.
The beneficial effects of the utility model: 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 the curved surface LGP is owing to being arc, save the space than the dull and stereotyped light-guiding lamp with 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 the use; Due to single LED lamp pearl just being set in the longitudinal section of curved surface LGP, obviously reduce than traditional LED fluorescent tube with the quantity of lamp pearl, so the cost of manufacture decrease.
