Technical field
The invention belongs to technical field of lighting fixtures, a kind of LED lamp is specifically related to.
Background technology
The design of LED lamp is general by a few part groups such as lamp casing, LED driver, LED light source plate, LED diffusers
Into, because the luminescence unit of LED is very small, luminescence unit can be freely formed, but illumination effect for light fixture in itself must
The whole structure of optically focused, floodlight must be met, the generation of dazzle is avoided as far as possible.
Dazzle refers to due to being not suitable for Luminance Distribution, or there is extreme brightness contrast in space or on the time in the visual field,
So that causing vision uncomfortable and reducing the visual condition of object visibility.The light sense that human eye cannot be adapted to is produced in the visual field
Feel, even detest, uncomfortable forfeiture legibility may be caused.In the visual field certain-there is too high brightness or front and rear in local area
There is excessive brightness change.Dazzle is one of the major reason for causing visual fatigue.
In the practical application of technical field of lighting fixtures such as LED lamp, it is known that the Main Function of diffuser is to use
To block the dazzle of LED, in the prior art, diffuser is usually installed in the outside of light source, in the middle position of diffuser
Certainly have light to appear, this just determines that the design of existing diffuser is merely able to reduce dazzle, it is impossible to fundamentally avoid dazzle
Generation.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, there is provided a kind of generation that completely avoid dazzle and tool
There is the LED lamp of unique illumination effect.
The technical solution adopted in the present invention is：A kind of LED lamp, by lamp housing 1, LED driver 2, LED light source plate 3 with
And diffuser 4 is constituted, the diffuser 4 is made up of integrally formed transmittance section 41 and the two parts of extension 42, the LED light source
The outside surrounding of plate 3 is distributed some LED lamp beads 31, and the center of inside of the LED light source plate 3 is provided with through hole 32, the extension
42 run through the through hole 32 and extend to the back of LED light source plate 3, and the LED driver 2 is fixed on LED light source plate 3
Back periphery.
Further technical scheme of the invention also includes：
The extension 42 is tapered, and to the back direction indent of LED light source plate 3.
The shape of the transmittance section 41 is engaged with the shape of extension 42, the transmittance section 41 is rounded, triangle, side
Shape or polygon.
The LED lamp bead 31 is evenly distributed on the outside surrounding of LED light source plate 3, the arrangement shape and printing opacity of LED lamp bead 31
The profile in portion 41 is consistent.
The LED lamp also includes support 5 and base 6, and the LED lamp is fixed on base 6 by support 5.
Compared with prior art, beneficial effects of the present invention are：In the present invention, by integrally formed on printing opacity cover structure
Light portion and extension two parts are constituted, and are recessed by by the extension of diffuser, after LED light source plate is recessed into always
Side, illumination less than position, with reference to the arrangement mode of LED lamp bead, so as to reach luminous uniform floodlight effect, it is entirely avoided
The generation of dazzle；From the appearance, the light-emitting area of light fixture of the present invention is indent, and after energization, the center display one of light-emitting area is black
Hole, forms unique illumination effect.

Specific embodiment
The present invention is further described below in conjunction with accompanying drawing.
Embodiment one
Refer to Fig. 1, Fig. 2, a kind of LED lamp of the present embodiment, by lamp housing 1, LED driver 2, LED light source plate 3 and thoroughly
Light shield 4 is constituted, wherein, diffuser 4 is made up of integrally formed transmittance section 41 and the two parts of extension 42, outside LED light source plate 3
Portion's surrounding is distributed some LED lamp beads 31, and through hole 32 is provided with the center of inside of LED light source plate 3, and extension 42 runs through the through hole
32 and the back of LED light source plate 3 is extended to, LED driver 2 is fixed on the back periphery of LED light source plate 3.
In the present embodiment, diffuser 4 is made up of integrally formed transmittance section 41 and the two parts of extension 42 in structure, prolongs
Exhibition portion 42 is tapered, and to the back direction indent of LED light source plate 3；The shape of transmittance section 41 matches with the shape of extension 42
Close, transmittance section 41 can be circle, triangle, square or polygon, correspondingly, extension 42 be shaped as curved surface circular cone,
Pyrometric cone, side's cone or polyhedral cone, in the present embodiment, transmittance section 41 is circle, the cone in curved surface of extension 42.
LED lamp bead 31 is evenly distributed in the outside surrounding of LED light source plate 3, the arrangement shape of LED lamp bead 31 and transmittance section
