Abstract
The invention discloses an efficient light-emitting diode (LED) fluorescent lamp tube, which comprises a lamp case, an LED light source and a light outlet cover, wherein the LED light source is fixedly arranged in the lamp case, the light outlet cover is arranged on the lamp case and covers the LED light source, reflecting surfaces are formed at two sides of the inner wall of the lamp case, a reverse V-shaped reflecting body upwards extends from the bottom in the lamp case, the reflecting surfaces are inwards recessed for forming an installing groove for accommodating the LED light source, the LED light source is fixedly arranged in the installing groove, the light outlet surface of the LED light source is right against the reverse V-shaped reflecting body, the bottom surface of the installing groove mutually forms an included angle at one end near the bottom of the lamp case, and the included angle is between 0 and 60 degrees. The LED fluorescent lamp tube adopts a reflecting type light outlet structure, the LED light rays are prevented from being directly irradiated into the eyes, the technical defect of glaring in the prior art is overcome. Simultaneously, the light rays are subjected to the secondary light distribution through the reflecting surfaces, and LED light spots are more uniform, so the light outlet effect of the LED fluorescent lamp tube can be obviously improved.
Description
[technical field]
The present invention relates to a kind of fluorescent tube, refer in particular to a kind of efficient LED fluorescent tube.
[background technology]
Advantages such as the high light efficiency of light emitting diode (LED) tool, low radiation, low power consumption, life-span length, low driving voltage, startup are quick, environmental protection, antidetonation resistance to compression, light fixture Miniaturizable; Be widely used at present as the lighting device of fluorescent light source with LED, be used for place of gas fluorescence formula fluorescent lamp.
Existing LED fluorescent lamp is usually by the cylindricality light-transmission tube and be installed in the fluorescent tube led light source substrate and form.For the illumination angle and the scattering uniformity that improves the LED fluorescent lamp, the light emitting diode (LED) of multiple row can be installed on the led light source substrate, and in the material of making lampshade, add the light scattering property that diffusion particle increases lampshade.But the LED light in the above-mentioned this LED fluorescent tube all directly sees through light-transmission tube and shoots out, and light pipe is transparent, and human eye directly can be seen the lamp pearl, is easy to generate dazzle.Adopted the fluorescent tube of frosted afterwards, human eye can avoid directly seeing LED lamp pearl, but the defective of dazzle does not still obtain the solution of essence, and the light of LED is direct irradiation people's eyes still, makes the people produce dizzy bad reaction.
[summary of the invention]
There is the technological deficiency of dazzle to LED fluorescent tube in the prior art, the object of the present invention is to provide a kind of reflection-type free from glare LED fluorescent tube.
In order to reach above-mentioned technical purpose; The technical scheme that the present invention taked is a kind of efficient LED fluorescent tube, comprises lamp housing, is fixed on the led light source in the lamp housing and is installed in the light shield that goes out that covers led light source on the lamp housing, and said envelope inner wall both sides form reflecting surface; Bottom in lamp housing is upwards stretched out one and is fallen " V " type reflector; Said reflecting surface caves in and forms the mounting groove of ccontaining led light source, and said led light source is fixed in the said mounting groove, and the exiting surface of said led light source is over against falling " V " type reflector; The bottom surface of said mounting groove is mutually an angle at the end near the lamp housing bottom, and said angle is between 0 °～60 °.
Preferably, the surface of said " V " type reflector is ripple type.
Preferably, said reflecting surface is ripple type.
Preferably, said led light source comprises substrate and is fixed on the plurality of LEDs on the substrate, and said mounting groove and said substrate are complementary, and said substrate is fixed in the mounting groove.
Preferably, the angle that is mutually of the bottom surface of said mounting groove is 30 °.
Preferably, said LED is a great power LED.
LED fluorescent tube of the present invention has adopted the structure of reflective bright dipping, has avoided the light direct irradiation human eye of LED, has eliminated the technological deficiency that has dazzle in the prior art.Because light through the secondary light-distribution of reflecting surface, can make the hot spot of LED more even, therefore can obviously improve the light effect that of LED fluorescent tube simultaneously.
[description of drawings]
Shown in Figure 1 is cross sectional representation of the present invention;
Shown in Figure 2 for the structural representation of lamp housing of the present invention;
[specific embodiment]
For further detailed elaboration technical scheme of the present invention, be elaborated below in conjunction with accompanying drawing.
Like Fig. 1, shown in Figure 2; The invention discloses a kind of efficient LED fluorescent tube; Comprise lamp housing 1, be fixed in the lamp housing 1 led light source 2a, 2b and be installed in cover led light source 2a, 2b on the lamp housing 1 go out light shield 4; Said lamp housing 1 inwall both sides form reflecting surface 10a, 10b, and the bottom lamp housing 1 in is upwards stretched out one and fallen V " 10a, 10b fall into the ccontaining led light source 2a of formation, the mounting groove 1a of 2b, 1b in the type reflector 11, said reflecting surface; said led light source 2a, 2b are fixed in mounting groove 1a, the 1b; the exiting surface of said led light source 2a, 2b just falls two side 11a, the 11b of " V " type reflector 11, and the bottom surface of said mounting groove 1a, 1b is mutually an angle theta at the end near lamp housing 1 bottom, and said angle theta is between 0 °～60 °.
As shown in Figure 2, reflecting surface 10a according to the invention, 10b are the reflecting surface of ripple type, so that farthest change the rising angle of reflection ray, reduce total reflection, improve light extraction efficiency.
Led light source 2a according to the invention comprises substrate 21 and is fixed on the plurality of LEDs 22 on the substrate 21 that the exiting surface of said LED22 is over against the side 11a of reflector.Same led light source 2a comprises substrate 23 and is fixed on the plurality of LEDs 24 on the substrate 23 that the exiting surface of said LED24 is over against the side 11b of reflector.Said mounting groove 1a, 1b and said substrate 21,23 are complementary, and said substrate 21,23 is fixed on respectively in mounting groove 1a, the 1b.
The light propagation path of LED22 of the present invention is by the side 11a of LED22 to reflector; Light penetrates through going out light shield 4 after the side of reflector 11a reflection; Part light penetrates from going out light shield 4 after also can passing through the reflection once more of reflecting surface 10a; Said structure has been avoided LED22 light direct irradiation human eye, has eliminated the technical problem of dazzle of the prior art.
Reflecting surface 10a according to the invention, 10b are arcwall face or linear pattern inclined-plane.
The bottom surface of mounting groove 1a according to the invention, 1b is 30 ° in the angle theta that the end near lamp housing 1 bottom forms.
LED fluorescent tube of the present invention also can directly adopt plastic casing in the category that allows, to practice thrift cost.LED22 of the present invention, the 24 preferred great power LEDs that adopt.
LED fluorescent tube of the present invention has adopted the structure of reflective bright dipping, has avoided the light direct irradiation human eye of LED, has eliminated the technological deficiency that has dazzle in the prior art.Because light through the secondary light-distribution of reflecting surface, can make the hot spot of LED more even, therefore can obviously improve the light effect that of LED fluorescent tube simultaneously.
The above only with convenient explanation the present invention, in not breaking away from creation spirit category of the present invention, knows this technological any simple modification and distortion that personnel did, still belongs to protection scope of the present invention.
