Background technology
At present, the LED fluorescent lamp is to install in the one side of substrate to drive substantially, in the luminous design of another side configuration LED illuminator of substrate, the lighting angle maximum angle that adopts the LED fluorescent lamp of this design is 180 degree angles, can not be satisfied with many light fixtures for the luminous requirement of fluorescent tube 360 degree; The light source module that the LED fluorescent lamp that has adopts single LEDs illuminator to combine, this strengthens the diffusion concentration of diffuser and makes the exiting surface even light mixing with regard to needs, this measure greatly reduces the light extraction efficiency of fluorescent tube, and because the LED illuminator of different batches is difficult to avoid the LED fluorescent lamp aberration to occur.
The utility model content
Technical problem to be solved in the utility model is: a kind of LED fluorescent lamp is provided, can not only 360 the degree full-shapes luminous, and bright dipping is even, has improved light extraction efficiency simultaneously.
For solving the problems of the technologies described above, the utility model proposes a kind of LED fluorescent lamp, comprise fluorescent tube, LED illuminator and circuit substrate, described LED illuminator is arranged on some circuit substrates, circuit substrate runs through the two ends that are fixed on fluorescent tube behind the fluorescent tube, and it is luminous towards the radial direction of fluorescent tube that described circuit substrate surrounds the fixedly connected LED of making illuminator energising back along the edge of fluorescent tube axial direction.
Further, comprise also being contained in the bracing frame that is column in the fluorescent tube that the two ends of bracing frame are fixed on the two ends of fluorescent tube, described circuit substrate is fixedly installed on the bracing frame surface along the bracing frame axial direction.
Further, the support frame as described above surface is provided with fixed block, and this fixed block is connected to the inner surface of fluorescent tube.
Further, support frame as described above and the fixed block structure that is formed in one.
Further, the surface of described fixed block and bracing frame is formed with the draw-in groove that extends along the bracing frame axial direction, and the edge of circuit substrate fixedly is fastened in the draw-in groove.
Further, the shape of cross section of support frame as described above is square or equilateral triangle or other how much polygons.
Further, support frame as described above is hollow column.
Further, described LED illuminator is the blue-ray LED illuminator.
Further, described fluorescent tube is PC tubing.
Further, be provided with fluorescent material in the described fluorescent tube.
Technique scheme has following beneficial effect at least: the utility model is arranged on some circuit substrates at the LED illuminator by adopting, circuit substrate runs through the two ends that are fixed on fluorescent tube behind the fluorescent tube, described circuit substrate surrounds the fixedly connected LED of making illuminator energising back along the edge of fluorescent tube axial direction luminous towards the circumferencial direction of fluorescent tube, not only can 360 the degree full angles luminous, and bright dipping is even, has improved light extraction efficiency simultaneously.
Description of drawings
