The utility model content
The LED fluorescent lamp that the utility model is designed is mainly used in various room lighting occasions.The LED fluorescent lamp that adopts technology described in the utility model to make is compared with the LED fluorescent lamp of prior art manufacturing, and the life-span is longer, and brightness is more stable, more even light emission, and production technology is simpler.
The technical solution of the utility model is: a kind of LED fluorescent lamp is characterized in that building block is: fluorescent tube (1), led light source mould bar (2) and lamp holder (3).Led light source mould bar (2) is fixed in the fluorescent tube (1), has circuit that led light source mould bar (2) is linked to each other with lamp holder (3), and lamp holder (3) is fixed on fluorescent tube (1) two ends.
Wherein said fluorescent tube composition material is fluorescent material and transparent polymer material, and the mass ratio of fluorescent material and transparent polymer material is 1: (5-20), fluorescent tube thickness is 0.5-5mm.
Described transparent polymer material is: Merlon or acrylic or polypropylene or polyester resin, optimization polycarbonate, acrylic.
Described led light source mould bar comprises blue light and two kinds of light sources of ruddiness, and wherein blue light source is 1 with the quantity ratio of red-light source: (0-2), and preferred 1: (0-0.1).
Described led light source mould bar does not contain fluorescent material.
The utility model also provides the manufacture method of above-mentioned fluorescent tube, and its concrete steps are:
(1) the respectively fluorescent material and the transparent polymer material raw material of weighing certain mass in proportion;
(2) fluorescent material and transparent polymer material raw material are mixed after, add in the extruder;
(3) configure the temperature and the speed of extruder, the mixture of fluorescent material and transparent polymer material is evenly extruded;
(4) with methods such as mold pressing or injection mo(u)ldings the fluorescent material extruded and the mixture of transparent polymer material are made required fluorescent tube.
Beneficial effect
Adopt the LED fluorescent lamp of the utility model manufacturing to compare, have the following advantages with the LED fluorescent lamp of prior art manufacturing:
(1) since fluorescent material and chip no longer be in contact with one another, the quantum efficiency of fluorescent material can be consistent in the long time, and remain on higher level, this just makes the brightness of LED fluorescent lamp keep unanimity in the long time, and has directly prolonged the life-span of LED fluorescent lamp.
(2) owing to adopted the fluorescent material fluorescent tube, no longer need to encapsulate independent white LED light source, manufacturing process is greatly simplified, especially saved loaded down with trivial details letter sorting operation, this has directly improved production efficiency.
(3) owing to adopted the fluorescent material fluorescent tube, the white light LEDs bulb that produces is a uniform surface light source, has effectively solved the zebra stripes problem in traditional LED fluorescent lamp.
