Board group is at and every group of reflector is in integrally approximate bowl structure, and LED major parts light after baffle reflection by mask by being transmitted
Out.
In said program, by the way that the left and right side walls of cavity are arranged to the angle of horizontal plane be 65 ° ~ 75 °, and will be anti-
Emitter is arranged to approximate bowl structure, after so that most of light that the LED in left and right side walls is sent out is passed through the reflection of reflector by
Mask transmits, only fraction remaining light direct irradiation human eye, can effectively reduce dazzle.
Preferably, the reflector is made of one group of approximation bowl structure.
Preferably, the reflector by two groups relatively in symmetrical approximate bowl structure constitute.Two groups of reflectors are set
Dazzle can be not only effectively reduced, and can ensure the intensity of LED light to avoid the interference phenomenon of light.
Preferably, in order to be further reduced dazzle, the height of each reflecting plate in every group of reflector by it is intermediate to the left and right
Both sides are incremented by.
Preferably, in order to be further reduced dazzle, the angle of first reflecting plate and horizontal plane in every group of reflector is-
35 ° ~ -25 °, the angle of the last one reflecting plate and horizontal plane is 25 ° ~ 35 °, the folder of reflecting plate and horizontal plane between the two
Gradually uniform increments are contended, and first reflecting plate and the absolute value of the last one reflecting plate angle with horizontal plane are identical.And it will
The absolute value of first reflecting plate and the angle of the last one reflecting plate and horizontal plane is arranged to identical numerical value, it is ensured that LED
The uniformity of light extraction after light reflection.
Preferably, in order to further reduce dazzle, reflecting plate is arranged to curved-surface structure
Preferably, in every group of reflector each bending direction of reflecting plate and the bending direction of this group of reflector on the contrary, and
The curvature of each reflecting plate is -0.0470 ~ 0.
Preferably, in order to increase the illumination of anti-glare floodlight, lighting module is arranged to four groups, and four groups of lighting modules are in
Matrix pattern arranges.
Compared with prior art, the beneficial effects of the invention are as follows：
A kind of anti-glare floodlight of the present invention is made by the way that reflector is arranged to approximate bowl structure in left and right side walls
It is transmitted by mask after the reflection that most of light that LED is sent out passes through reflector, only fraction remaining light direct irradiation people
Eye, can effectively reduce dazzle；It is dizzy reducing by symmetrical approximation bowl structure during reflector is arranged to two groups relatively
While light, it can ensure the intensity of LED light to avoid the interference phenomenon of light；By the way that reflector is arranged to multiple not rounded slip over
The reflecting plate crossed can prevent reflected light exiting parallel and cause the defect of dazzle；By the way that reflecting plate is arranged to curved-surface structure,
The contact area of reflecting plate and light can be increased, so that more light are mapped on curved surface after the reflection of curved surface by mask 2
It projects, helps further to reduce dazzle.

Embodiment
A kind of anti-glare floodlight structure of the present embodiment is as shown in Figure 1 to Figure 3, including four groups of lighting modules 1, and four groups of illuminations
Module 1 is arranged in matrix pattern, can increase the illumination of anti-glare floodlight in this way；Lighting module 1 includes a cavity, the front of cavity
And rear portion is respectively equipped with mask 2 and at least one set of reflector 3, and every group of reflector 3 is whole in approximate bowl structure, the present embodiment
In, reflector 3 is two groups, and two groups of reflectors 3 are symmetrical with respect to center line, as shown in Figures 2 and 3；The left and right side walls and water of cavity
The angle of plane is 65 ° ~ 75 °, and left and right side walls are symmetrical with respect to center line, and several LED are equipped in left and right side walls；Every group of reflection
Device 3 is made of the reflecting plate 31 of multiple non-rounding ofves, and in the present embodiment, every group of reflector 3 is made of four reflecting plates 31,
LED major parts light is transmitted after being reflected by reflecting plate 31 by mask 2.
In use, anti-glare floodlight is connected power supply, the LED light in the left and right side walls of 1 cavity of lighting module is powered concurrent
Light, the most of light sent out from LED are irradiated on reflector 3 and are transmitted by mask 2 after the reflection of reflector 3, only
Fraction remaining light direct irradiation human eye, can effectively reduce dazzle.The left and right side walls of cavity, which are arranged to angle with horizontal plane, is
65 ° ~ 75 °, with this limit LED light to reflector 3 incidence angle, it can be ensured that more light after the reflection of reflector 3 again
It is projected by mask 2, it is possibility to have effect reduces dazzle；Symmetrical approximation bowl structure during reflector 3 is arranged to two groups relatively,
While effectively reducing dazzle, it can ensure the intensity of LED light to avoid the interference phenomenon of light；Reflector 3 is arranged to multiple
The reflecting plate 31 of non-rounding off can prevent reflected light exiting parallel and cause the defect of dazzle.
To facilitate installation, four groups of lighting modules 1 can be placed in frame 4, and frame 4 is fixed in mounting bracket 5,
As shown in Figure 1, mounting bracket 5 is equipped with mounting hole, facilitates and anti-glare floodlight is mounted on designated position.
Wherein, the height of four reflecting plates 31 in every group of reflector 3 is incremented by by intermediate both sides to the left and right, specifically,
The angle of first reflecting plate 32 and horizontal plane in every group of reflector 3 is -35 ° ~ -25 °, the last one reflecting plate 33 and water
The angle of plane is 25 ° ~ 35 °, the gradual uniform increments of angle of reflecting plate 31 and horizontal plane between the two, and first reflection
Plate 32 and the absolute value of the last one 33 angle with horizontal plane of reflecting plate are identical.Setting helps to be formed with sequence reflection in this way, makes
The more light sent out from LED are projected after the reflection of reflecting plate 31 by mask 2, can be further reduced dazzle；And
The absolute value of first reflecting plate and the angle of the last one reflecting plate and horizontal plane is arranged to identical numerical value, it is ensured that
The uniformity of light extraction after LED light reflection.
In addition, in every group of reflector 3 bending direction of each reflecting plate 31 and the bending direction of this group of reflector 3 on the contrary,
That is four reflecting plates 31 in every group of reflector 3 are the curved-surface structure of protrusion, the minimum curvature of first reflecting plate 32 is-
0.0248, the minimum curvature of second reflecting plate is -0.0461, and the minimum curvature of third reflecting plate is -0.0448, last
The minimum curvature of a reflecting plate 33 is -0.0419, and the maximum curvature of four reflecting plates 31 is 0.Curved-surface structure and light connect
Contacting surface product is big, and more light can be made to be mapped on curved surface and projected by mask 2 after the reflection of curved surface, contributed to further
Reduce dazzle.
Obviously, the above embodiment of the present invention be only to clearly illustrate example of the present invention, and not be pair
The restriction of embodiments of the present invention.For those of ordinary skill in the art, may be used also on the basis of the above description
To make other variations or changes in different ways.There is no necessity and possibility to exhaust all the enbodiments.It is all this
All any modification, equivalent and improvement etc., should be included in the claims in the present invention made by within the spirit and principle of invention
Protection domain within.
