Abstract

The utility model discloses an efficient LED fluorescent tube, which comprises a lamp shell, LED light sources and a light emergent cover. The LED light sources are fixed in the lamp shell, the light emergent cover is mounted on the lamp shell and covers on the LED light sources, reflecting surfaces are formed on two sides of the inner wall of the lamp shell, the inner bottom of the lamp shell upwards extends to form an inverted-'V'-shaped reflector, the reflecting surfaces are sunken to form mounting grooves for holding the LED light sources, the LED light sources are fixed in the mounting grooves, light emergent surfaces of the LED light sources face to the inverted-'V'-shaped reflector, and an included angle is formed between one ends, close to the bottom of the lamp shell, of the bottoms of the mounting grooves and ranges from 0 degree to 60 degrees. A reflecting light emergent structure is adopted, the problem that light of LEDs directly illuminates eyes of human bodies is avoided, and the technical shortcoming of glare in the prior art is overcome. Besides, as the light is secondarily distributed by the reflecting surfaces, light spots of the LEDs can be more uniform, and a light emergent effect of the LED fluorescent tube can be improved obviously.

Description

A kind of efficient LED fluorescent tube

[technical field]

The utility model relates to a kind of fluorescent tube, refers 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.

[utility model content]

Have the technological deficiency of dazzle to LED fluorescent tube in the prior art, the purpose of the utility model 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 utility model is 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.

The LED fluorescent tube of the utility model 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.

Shown in Figure 2 is the structural representation of the utility model lamp housing;

[specific embodiment]

Technical scheme for further detailed elaboration the utility model is elaborated below in conjunction with accompanying drawing.

Like Fig. 1, shown in Figure 2; The utility model 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, the said reflecting surface 10a of the utility model, 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.

The said led light source 2a of the utility model 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 the utility model LED22 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.

The said reflecting surface 10a of the utility model, 10b are arcwall face or linear pattern inclined-plane.

The bottom surface of the said mounting groove 1a of the utility model, 1b is 30 ° in the angle theta that the end near lamp housing 1 bottom forms.

The LED fluorescent tube of the utility model also can directly adopt plastic casing in the category that allows, to practice thrift cost.The described LED22 of the utility model, the 24 preferred great power LEDs that adopt.

The above only with convenient explanation the utility model, in not breaking away from the creation spirit category of the utility model, knows this technological any simple modification and distortion that personnel did, still belongs to the protection domain of the utility model.
