Description

A kind of LED fluorescent lamp

Technical field

The utility model relates to lighting technical field, relates in particular to a kind of LED fluorescent lamp.

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.

The specific embodiment

Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.Below in conjunction with accompanying drawing the utility model is described further.

As depicted in figs. 1 and 2, the LED fluorescent lamp of the utility model embodiment comprises fluorescent tube 1, LED illuminator 2 and circuit substrate 3.

Fluorescent tube 1 is PC tubing, and fluorescent tube 1 inside has participated in fluorescent material, and fluorescent material makes whole piece fluorescent tube 1 surface send white light after being subjected to the exciting of blue-ray LED, and has improved light extraction efficiency and can make the fluorescent tube 1 of different batches reach uniformity preferably simultaneously; Circuit substrate 3 is the pcb plate of strip type, it also can be the circuit board of other types, such as adopting aluminium base, LED illuminator 2 is laid in the surface of circuit substrate 3, circuit substrate 3 runs through the two ends that are fixed on fluorescent tube 1 behind the fluorescent tube 1, and circuit substrate 3 surrounds the fixedly connected LED of making illuminator 2 energising backs along the edge of fluorescent tube 1 axial direction luminous towards the circumferencial direction of fluorescent tube 1, in the present embodiment, circuit substrate 3 is arranged in the fluorescent tube 1 by a bracing frame 4, bracing frame 4 is for being the bracing frame 4 of column, better in order to dispel the heat, bracing frame 4 adopts the ducted body column, and its shape of cross section is square, the two ends of bracing frame 4 are fixed on the two ends of fluorescent tube 1, in order to make bracing frame 4 fixing more firm, be provided with four fixed blocks 5 at bracing frame 4 lip-deep four crest lines, support frame as described above 4 and fixed block 5 structure that is formed in one, this fixed block 5 is connected to the inner surface of fluorescent tube 1, can prevent circuit substrate 3 swing radially in fluorescent tube 1 like this, and fixed block 5 is formed with the draw-in groove 6 that extends along bracing frame 4 axial directions with four side surfaces of bracing frame 4, and the edge of circuit substrate 3 fixedly is fastened in the draw-in groove 6.

As another embodiment, the shape of cross section of bracing frame 4 also can be equilateral triangle or other how much polygonal shapes.
