Abstract
The invention relates to a lighting device, in particular to an LED fluorescent lamp which comprises a lamp tube, a driving circuit board, a lamp bead distributing board, LED lamp beads, connectors and a light distributing board. The LED fluorescent lamp is characterized in that both ends of the lamp tube are fixedly connected with the connectors, the lamp bead distributing board is fixed in the lamp tube, and both ends of the lamp bead distributing board are connected with the connectors at both ends of the lamp tube; a plurality of LED lamp beads are distributed at one side of the lamp bead distributing board, one layer of light distributing board is fixed between the lamp bead distributing board and the LED lamp beads, and holes used for the projection of the lamp beads are reserved on the light distributing board; and the other side of the lamp bead distributing board is connected with the driving circuit board, and both the connectors and the lamp bead distributing board are electrically connected with the driving circuit board. The fluorescent lamp has high brightness, large irradiation angle and good heat radiation; compared with the traditional fluorescent lamp pole, the LED fluorescent lamp saves more energy, is environment friendly, has no stroboflash and longer service life, protects the eyes and has no harmful gas; and the LED fluorescent lamp is very suitable to places which need long-time stable light sources, such as classrooms, libraries and the like.
Description
Technical field
The present invention relates to lighting device, particularly a kind of LED fluorescent lamp.
Background technology
Fluorescent lamp is as a kind of comparatively energy-conservation cold light source, become industry and civilian in the lighting device that is most widely used, present most fluorescent lamps uses be fluorescent tube, but there are a lot of defectives in fluorescent tube, such as the fragile fracture easily of fluorescent tube, problem such as service life is short.
LED (LightEmitting Diode, light emitting diode) is a kind of solid-state semiconductor devices, and it can directly be converted into light to electricity, increasingly mature along with the LED technology, and led light source becomes optimal light source and removes to replace traditional light source.
Summary of the invention
The purpose of this invention is to provide a kind of LED fluorescent lamp, this fluorescent lamp brightness height, irradiating angle are big, good heat dissipation, and longer than the energy-conserving and environment-protective more of conventional fluorescent lamp stand, no stroboscopic, life-span, protection eyes, no pernicious gas; Being suitable for use in very much classroom, library etc. needs the place of stabilized light source for a long time.
The technical solution adopted for the present invention to solve the technical problems is: design a kind of LED fluorescent lamp, it comprises fluorescent tube, drive circuit board, lamp pearl distribution grid, LED lamp pearl, plug and luminous intensity distribution plate, it is characterized in that: lamp tube ends is fixedly connected with plug, be fixed with lamp pearl distribution grid in the fluorescent tube, lamp pearl distribution grid two ends are connected with the plug of lamp tube ends, lamp pearl distribution grid one side is distributed with some LED lamp pearls, be fixed with one deck luminous intensity distribution plate between lamp pearl distribution grid and the LED lamp pearl, leave the hole of stretching out on the luminous intensity distribution plate for LED lamp pearl, lamp pearl distribution grid opposite side is connected with drive circuit board, and plug and lamp pearl distribution grid all are electrically connected with drive circuit board.
Described fluorescent tube adopts half aluminium, half acrylic material to make.
The invention has the beneficial effects as follows: owing to change traditional fluorescent tube into LED lamp pearl, thereby make fluorescent lamp in that to reach under the situation of equal brightness power consumption littler, the LED fluorescent tube of 18W can replace the fluorescent tube of 40W; Simultaneously, because the fluorescent tube of this LED fluorescent lamp adopts half aluminium, half acrylic material to make, therefore well solved the heat dissipation problem of LED; Because the no stroboscopic of LED itself is protected eyes, therefore characteristics such as no pernicious gas are suitable for use in the place that classroom, library etc. need stabilized light source for a long time very much again.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the schematic diagram of LED fluorescent lamp of the present invention.
Among the figure: 1, fluorescent tube; 2, drive circuit board; 3, lamp pearl distribution grid; 4, LED lamp pearl; 5, plug; 6, luminous intensity distribution plate
The specific embodiment
As shown in Figure 1, the LED fluorescent lamp comprises fluorescent tube 1, drive circuit board 2, lamp pearl distribution grid 3, LED lamp pearl 4 and plug 5, fluorescent tube 1 two ends are fixedly connected with plug 5, be fixed with lamp pearl distribution grid 3 in the fluorescent tube 1, lamp pearl distribution grid 3 two ends are connected with the plug 5 at fluorescent tube 1 two ends, lamp pearl distribution grid 3 one sides are distributed with some LED lamp pearls 4, be fixed with one deck luminous intensity distribution plate 6 between lamp pearl distribution grid 3 and the LED lamp pearl 4, leave the hole of stretching out for LED lamp pearl 4 on the luminous intensity distribution plate 6, the light that LED lamp pearl 4 sends enlarges the irradiating angle of light by luminous intensity distribution plate 6; Lamp pearl distribution grid 3 opposite sides are connected with drive circuit board 2, plug 5 and lamp pearl distribution grid 3 all are electrically connected with drive circuit board 2, plug 5 is plugged on the conventional fluorescent lamp base, the 220V civil power is inserted in the LED fluorescent lamp, plug 5 is electrically communicated to the 220V city on the drive circuit board 2, drive circuit board 2 just 220V civil power is converted to direct current, and direct current is delivered on the lamppost distribution grid 3, light the LED lamp pearl 4 on the lamp pearl distribution grid 3, fluorescent tube 1 adopts half aluminium, half acrylic material to make, and has therefore well solved the heat dissipation problem that produces heat when LED lamp pearl 4 is lighted.
