Abstract
The utility model discloses an anti-glare light-emitting diode (LED) daylight lamp tube which comprises a lamp casing, an LED light source fixed in the lamp casing, and a light-emitting cover which is arranged on the lamp casing and covers the LED light source. Two sides of an inner wall of the lamp casing are provided with reflection faces. A protruding shoulder fixing the LED light source extends upward from the bottom of the LED casing. Left and right sides of the protruding shoulder are provided with installation grooves for installing and fixing the LED light source. The LED light source is installed and fixed in the installation grooves. Light-emitting faces of the LED light source directly face the reflection faces. The bottom faces of the installation grooves on the left and the right sides of the protruding shoulder form an included angle close to one end of the bottom of the lamp casing. The included angle ranges from 0 degree to 60 degrees. As reflection type light-emitting structure is adopted, the anti-glare LED daylight lamp tube avoids the fact that LED light directly shines on eyes of people, and eliminates the glaring technical defect in the prior art. LED light spots are even and light-emitting effects of the LED daylight lamp tube are remarkably improved due to the fact that light goes through the second distribution by the reflection faces.
Description
[technical field]
The utility model relates to a kind of fluorescent tube, refers in particular to a kind of glare prevention 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 glare prevention 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; The convex shoulder of a fixed L ED light source is upwards stretched out in bottom in lamp housing; The left and right sides of said convex shoulder is formed with the mounting groove that installs and fixes led light source, and said led light source is fixed in the mounting groove, and the exiting surface of said led light source is over against reflecting surface; The mounting groove bottom surface of the convex shoulder left and right sides is mutually an angle at the end near the lamp housing bottom, and said angle is between 0 °～60 °.
Preferably, the surface of said reflecting surface is a 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, said reflecting surface is arcwall face or linear pattern inclined-plane.
Preferably, the angle that is mutually of the mounting groove bottom surface of the said convex shoulder left and right sides is 30 °.
Preferably, said lamp housing outer surface is formed with many heat radiation convex tendons.
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.
[description of drawings]
Shown in Figure 1 is the cross sectional representation of the utility model;
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 glare prevention 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 convex shoulder 11 of a fixed L ED light source 2a, 2b is upwards stretched out in the bottom in lamp housing 1, and the left and right sides of said convex shoulder 11 is formed with mounting groove 11a, the 11b that installs and fixes led light source 2a, 2b; Said led light source 2a, 2b are fixed in mounting groove 11a, the 11b; The exiting surface of said led light source 2a, 2b is over against reflecting surface 10a, 10b, and the mounting groove 11a of convex shoulder 11 left and right sides, the bottom surface of 11b are mutually an angle theta at the end near lamp housing 1 bottom, and the angle theta that is mutually 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 reflecting surface 10a.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 reflecting surface 10b.Said mounting groove 11a, 11b and said substrate 21,23 are complementary, and said substrate 21,23 is fixed on respectively in mounting groove 11a, the 11b.
The light propagation path of the utility model LED22 be by LED22 to reflecting surface 10a, light has been avoided LED22 light direct irradiation human eye through going out light shield 4 ejaculations through reflecting surface 10a reflection back, 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.
