Current LED fluorescent tube majority is to adopt the lamp housing and the lamp socket that fasten, adds therein aluminium sheet radiator and pcb board to assemble.On platform-type radiator, settle the pcb board of horizontal positioned, the LED chip of arranging according to arrangement order of certain pitch arrangement, the LED lamp luminescence source of a wire of formation on this pcb board.
Lamp housing and lamp socket are to account for semicircle and the cylindrical structure that forms fluorescent tube, and the light sending from LED chip irradiates out from the semicircle lamp housing of printing opacity.In general, in order to improve the luminous efficiency of LED fluorescent tube, to greatest extent the light sending of LED all to be irradiated out, producer and design are invariably repeatedly to the angle between printing opacity lamp housing and pcb board, structure repeatedly designs and improves mutually, to obtaining the fluorescent tube of better illumination effect.
[summary of the invention]
The utility model has proposed a kind of structure variation for above problem, and the LED fluorescent tube of three-dimensional pcb board framework, can improve lighting angle, and expands light extraction efficiency.
The LED fluorescent tube that relates to described in the utility model, comprise fluorescent tube, lamp holder and be installed in pcb board and the LED chip in fluorescent tube, it is characterized in that, from fluorescent tube cross section, this pcb board doubling angulation is towards " ∠ " of fluorescent tube shape, doubling and the pcb board of angle is divided into the first pcb board, the second pcb board, the limit that two pcb boards connect is concentric with fluorescent tube axis; Two inclined-planes that the first pcb board and the second pcb board have, uniform single-row plurality of LEDs chip on each inclined-plane.
This fluorescent tube comprises light diffusion part and photo-emission part, and both are one-body molded is tubular fluorescent tube.
Be provided with pcb board fixed bit at photo-emission part, have radiator aluminium base plate at pcb board fixed bit.
From the circular cross section of fluorescent tube, the right central angle of the light diffusion part of fluorescent tube is 200 °～260 °, and the right central angle of photo-emission part is 100 °～160 °.
On the first pcb board and the second pcb board, LED chip number equates, the LED chip of the first pcb board and the second pcb board misplaces and arranges on fluorescent tube axis direction.
This fluorescent tube comprises light diffusion part and photo-emission part, and both are one-body molded is tubular fluorescent tube, adopts dust-proof card buckle structure to connect between lamp tube ends and lamp holder; Around the pcb board of installing, be coated with reflector in fluorescent tube, form full angle light reflection structure with photo-emission part.
The utility model has been made the pcb board of arranging LED chip the stereochemical structure of cusp configuration, can arrange more LED chip, and kept the relative spacing of LED chip in the fluorescent tube in identical aperture, has improved the illuminance of light fixture.In conjunction with the reflector on pcb board, can form more effectively full angle light reflector system, reduce light consumption, improve the efficiency of light energy utilization, more save the energy.
