Abstract
The utility model discloses an LED (light-emitting diode) fluorescent lamp. The LED fluorescent lamp comprises a plurality of LED luminous bodies, an elongated PCB (printed circuit board), a radiator, two lamp caps and a circular lamp hood, wherein the plurality of LED luminous bodies are uniformly distributed on the elongated PCB; the radiator is a circular arc; the circular lamp hood is clamped on the outer side of the lower part of the radiator; the two lamp caps are sleeved at two ends of the circular lamp hood and the radiator; an elongated groove is arranged in the middle of the lower end face of the radiator; two inclined planes which incline downwards are arranged on two sides of the groove; reflective paper is attached on the two inclined planes; the elongated PCB is arranged on the groove; the elongated PCB board is connected with the LED drive circuit internally arranged in the lamp tube through a lead or connected with an external LED drive circuit through the two lamp caps; preferably the centre of a light outlet surface of each LED luminous body is overlapped with the centre of the cross section of the lamp tube, and preferably an included angle between the reflective surfaces of two pieces of reflective papers and the lower end face of the PCB is 164 degrees. The LED fluorescent lamp disclosed by the utility model is large in irradiation angle, and uniform and soft in outlet light.
Description
Technical field
The utility model relates to field of illumination lamp technology, especially a kind of LED fluorescent lamp.
Background technology
In field of illumination lamp technology, to compare with traditional light source, the LED illuminator has advantages such as low power consuming, long-life, environmental protection, antidetonation, and the LED fluorescent lamp that adopts the LED illuminator to process progressively replaces traditional fluorescent tube; But present LED fluorescent tube on the market generally is that a pcb board is installed in the fluorescent tube that is made up of radiator and lampshade; One row or multiple row LED illuminator are set on the pcb board form light source; Because the LED illuminator is all to same angular illumination; Make that the light angle of LED fluorescent tube is not enough, bright dipping is inhomogeneous, influences lighting quality.
The utility model content
The technical problem that the utility model will solve provides a kind of LED fluorescent lamp, and irradiating angle is big, and bright dipping is softer.
For achieving the above object, the technical scheme of the utility model is: a kind of LED fluorescent lamp comprises a plurality of LED illuminators, strip pcb board, radiator, two lamp holders, circular arc lampshade; A plurality of LED illuminators are evenly distributed on the strip pcb board; Radiator is a circular arc, and the outside, radiator bottom is provided with two draw-in grooves, and the circular arc lampshade is stuck on two draw-in grooves of radiator bottom; Two lamp sleeves are at the two ends of circular arc lampshade and radiator; The centre of radiator lower surface is provided with a strip groove, and the both sides of groove are provided with two inclined downward, all posts reflective sheeting on described two inclined-planes; The strip pcb board is installed on the described groove, the strip pcb board through lead be built in fluorescent tube in led drive circuit or be connected with external led drive circuit through two lamp holders.
The center of the exiting surface of preferred said each LED illuminator and the center overlaid of fluorescent tube cross section.
The top of the reflective surface of preferred said two reflective sheetings and the lower surface overlaid of pcb board.
The angle of the reflective surface of preferred said two reflective sheetings and the lower surface of pcb board is 164 °.
The utility model is provided with downward-sloping reflective sheeting because the strip pcb board is installed on the middle groove in radiator lower surface and in the both sides of a plurality of LED illuminators; Refraction action through reflective sheeting; Make the irradiating angle of whole light fixture greatly improve; Bright dipping simultaneously is also softer; Particularly when the center of the exiting surface of each LED illuminator and the center overlaid of fluorescent tube cross section, when the angle of the reflective surface of two reflective sheetings and the lower surface of pcb board is 164 °, the irradiating angle of whole fluorescent tube and bright dipping best results.

The specific embodiment
Below in conjunction with accompanying drawing and concrete embodiment the utility model is done further explain.
Fig. 1, shown in Figure 2; A kind of LED fluorescent lamp comprises a plurality of LED illuminator 1, strip pcb board 2, radiator 3, two lamp holders 4, circular arc lampshade 5, and a plurality of LED illuminators 1 are evenly distributed on the strip pcb board 2; Radiator 3 is a circular arc; The outside, radiator 3 bottoms is provided with two draw-in grooves 31,32, and circular arc lampshade 5 is stuck on two draw-in grooves 31,32 of radiator 3 bottoms, and two lamp holders 4 are enclosed within the two ends of circular arc lampshade 5 and radiator 3; The centre of radiator 3 lower surfaces is provided with a strip groove 33; The both sides of groove 33 are provided with two inclined downward 34,35, post reflective sheeting 6 on the inclined-plane 34, post reflective sheeting 7 on the inclined-plane 35; Strip pcb board 2 is installed on the described groove 33, strip pcb board 2 through lead be built in fluorescent tube in led drive circuit or be connected with external led drive circuit through two lamp holders 4.
The position of preferred each LED illuminator 1 is the center of its exiting surface and the center overlaid of fluorescent tube cross section.
The paste position of preferred two reflective sheetings 6,7 is the top of its reflective surface and the lower surface overlaid of pcb board 2.
The paste position of preferred two reflective sheetings 6,7 is 164 ° for the angle of the lower surface of its reflective surface and pcb board 2.
Below only be preferred embodiment of the utility model, the change that those skilled in the art does to be equal to by claim all falls into the protection domain of this case.
