Abstract
The utility model aims to provide a separate type power supply LED light pipe capable of reducing the heat inside the light pipe. The LED light pipe comprises a power supply adapter, a lamp screen, and a lamp holder arranged on both ends of the lamp screen. An LED lamp board is arranged in the lamp screen. A plurality of LED lamps are arranged on the LED lamp board. In particular, the power supply adapter is arranged outside the lamp screen, and is separate from the lamp screen. The power supply adapter comprises an encloser and a circuit board arranged inside the encloser. The encloser is sealed with insulation paste. The power supply adapter is provided with a conducting wire or a conducting post electrically connected with the LED lamps in the lamp screen. The power supply of the LED light pipe is arranged outside the lamp screen, thus effectively reducing the heat inside the light pipe, reducing the working temperature of the entire light pipe and prolonging the service life of the LEDs.
Description
Technical field
It is the light pipe of light source with LED that the utility model relates to a kind of.
Background technology
In present lighting engineering, the light pipe of use led lighting has obtained consumer's approval gradually, and than traditional fluorescent lamp, it has low, the no stroboscopic of energy consumption, long, free of contamination advantage of life-span, has represented the developing direction of green illumination.But existing LED light pipe is because built-in driving power, and power supply can produce more heat when work, accumulate in light pipe inside, is difficult to distribute, to very big influence is arranged in service life of LED.
Summary of the invention
The purpose of this utility model is to propose a kind of LED light pipe that can reduce the separate power supply of light pipe inner heat.
LED light pipe of the present utility model comprises the lamp socket at power supply adaptor, lampshade and lampshade two ends, be provided with the LED lamp plate in the described lampshade, a plurality of LED lamps are housed on the LED lamp plate, particularly described power supply adaptor is arranged on the lampshade outside and separates with lampshade, power supply adaptor comprises housing and is arranged on the circuit board of enclosure interior, described housing utilizes insulating cement sealing, described power supply adaptor to have lead or conductive pole to pass lampshade and is electrically connected with LED lamp in the lampshade.
Described power supply adaptor can be assemblied in according to the situation of reality the LED light pipe near, for example be assemblied in the ballast place of conventional fluorescent pipe.
LED light pipe of the present utility model is by being arranged on power unit the lampshade outside, and separates with lampshade, effectively reduces the heating of light pipe inside, reduced the temperature when overall optical plumber does, and prolonged the service life of LED.
Description of drawings
Fig. 1 is the structural representation of embodiment 1;
Fig. 2 is the cutaway view at the A-A place of Fig. 1.
The specific embodiment
Embodiment 1:
LED light pipe of the present utility model comprises the lamp socket 3 at power supply adaptor 1, lampshade 2 and lampshade 2 two ends, be provided with LED lamp plate 4 in the described lampshade 2, a plurality of LED lamps 5 are housed on the LED lamp plate 4, particularly described power supply adaptor 1 is arranged on lampshade 2 outsides and separates with lampshade 2, power supply adaptor 1 comprises housing and is arranged on the circuit board of enclosure interior, described housing utilizes insulating cement sealing, described power supply adaptor 1 to have lead or conductive pole to pass lampshade 2 and is electrically connected with LED lamp 5 in the lampshade 2.
LED light pipe of the present utility model is provided with LED lamp plate support 6 in lampshade 2, described LED lamp plate support 6 cross sections are semicircle, and both sides are provided with draw-in groove 61, and LED lamp plate 4 snaps in the draw-in groove 61 of LED lamp plate support 6.Not only convenient by this assembling mode of draw-in groove, reduced the cost of screw, and because the position that LED lamp plate support 6 and LED lamp plate 4 are fixed is the both sides of whole piece LED lamp plate 4, structure is more firm, LED lamp plate support 6 can block the welding foot and the power circuit at LED lamp plate 4 back sides simultaneously, plays beauty function.
The circuit of described power supply adaptor 1 comprises rectification circuit and constant-current circuit, can be direct current with AC rectification, and reduces the electric current of LED lamp, the unexpected variation of voltage, prolongs the service life of LED lamp.Because rectification circuit, constant-current circuit have been to use commonplace electronic technology at present, repeat no more herein.
Described lampshade 2 is transparent or translucent.Adopt transparent lampshade, the light transmittance of LED light pipe can be higher; Adopt translucent lampshade, the light that the whole LED light pipe sends can be more even, soft, even certain LED lamp breaks down, the consumer can not experience outside yet.The most handy glass, the plastic or other material of handling through frosted of translucent lampshade made, and cheap, processing is simple, and effect is also fine.
LED light pipe of the present utility model is by being arranged on power unit the lampshade outside, and separates with lampshade, effectively reduces the heating of light pipe inside, reduced the temperature when overall optical plumber does, and prolonged the service life of LED.
Claims (5)
