The technical solution of the utility model is such: a kind of LED fluorescent tube, comprise the flute profile body, in the flute profile body, be provided with the aluminium base of strip, along being arranged at intervals with a plurality of LED lamps on the length direction of aluminium base, on the notch of flute profile body, be provided with diffuser, be provided with end socket, be equipped with two electrode tips in the end socket outer face of end, flute profile body both sides in end, flute profile body both sides, wherein, be provided with the secondary optics Light modulating device between described LED lamp and the diffuser.
In above-mentioned a kind of LED fluorescent tube, described secondary optics Light modulating device is collector lens or collector lens group; The secondary optics Light modulating device is the combination of taper reflection shield or taper reflection shield group and the even mating plate of secondary optics, and taper reflection shield or taper reflection shield group are positioned at the LED lamp outside, and the even mating plate of secondary optics is positioned at the diffuser inboard.
In above-mentioned a kind of LED fluorescent tube, described flute profile body is provided with the heat radiation groove, to strengthen radiating effect.
In above-mentioned a kind of LED fluorescent tube, described diffuser can be flat armorplate glass or PC plate or poly (methyl methacrylate) plate; Diffuser also can adopt circular-arc PC plate or poly (methyl methacrylate) plate.
In above-mentioned a kind of LED fluorescent tube, when the flute profile body is longer, can also be provided with at flute profile body middle part and drives section, be used for installation of driver.
After the utility model adopts said structure, under in shape can identical with traditional fluorescent tube substantially situation, utilize the LED lamp to throw light on, can significantly reduce the energy consumption of fluorescent tube, and long service life, replaceable traditional fluorescent tube is used for indoor and outdoor illumination; By the secondary optics Light modulating device is set, can eliminate luminous dazzling, the deficiency of dazzling the eyes and be easy to generate hot spot of LED lamp source, improve the illuminating effect of light fixture.
