Description
Technical field
The utility model belongs to technical field of lighting fixtures, is specifically related to a kind of LED lamp.
Background technology
The design of LED lamp is typically by a few part groups such as lamp casing, LED driver, LED light source board, LED diffusers
Into, because LED luminescence unit is very small, luminescence unit can be freely formed, but must for the illumination effect of light fixture in itself
The whole structure of optically focused, floodlight must be met, avoid the generation of dazzle as far as possible.
Dazzle refers in the visual field due to being not suitable for Luminance Distribution, or extreme brightness contrast be present in space or on the time,
So that cause vision uncomfortable and reduce the visual condition of object visibility.The light sense that human eye can not adapt 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
Excessive brightness change occurs.Dazzle is to cause one of major reason of 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 LED dazzle, 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, can not fundamentally avoid dazzle
Generation.
The content of the invention
The purpose of this utility model is overcome the deficiencies in the prior art, there is provided a kind of generation that completely avoid dazzle,
And the LED lamp with unique illumination effect.
Technical scheme is used by the utility model：A kind of LED lamp, by lamp housing 1, LED driver 2, LED light source board
3 and diffuser 4 form, the diffuser 4 is made up of integrally formed transmittance section 41 and the two parts of extension 42, the LED
The outside surrounding of light source board 3 is distributed some LED lamp beads 31, and the center of inside of the LED light source board 3 is provided with through hole 32, described to prolong
Exhibition portion 42 is through the through hole 32 and extends to the back of LED light source board 3, and the LED driver 2 is fixed on LED light source
The back periphery of plate 3.
The further technical scheme of the utility model also includes：
The extension 42 is tapered, and to the back direction indent of LED light source board 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 board 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, the beneficial effects of the utility model are：In the utility model, by one on printing opacity cover structure
The transmittance section of shaping and extension two parts composition, by the way that the extension depression of diffuser is gone down, LED light source is recessed into always
The rear of plate, illumination less than position, with reference to the arrangement mode of LED lamp bead, so as to reach luminous uniform floodlight effect, completely
Avoid the generation of dazzle；From the appearance, the light-emitting area of the utility model light fixture is indent, after energization, the center of light-emitting area
A black hole is shown, forms the illumination effect of uniqueness.

Embodiment
The utility model 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 board 3 and thoroughly
Light shield 4 forms, wherein, diffuser 4 is made up of integrally formed transmittance section 41 and the two parts of extension 42, outside LED light source board 3
Portion's surrounding is distributed some LED lamp beads 31, is provided with through hole 32 in the center of inside of LED light source board 3, extension 42 runs through the through hole
32 and the back of LED light source board 3 is extended to, LED driver 2 is fixed on the back periphery of LED light source board 3.
In the present embodiment, diffuser 4 is made up of in structure integrally formed transmittance section 41 and the two parts of extension 42, is prolonged
Exhibition portion 42 is tapered, and to the back direction indent of LED light source board 3；The shape of transmittance section 41 matches with the shape of extension 42
