Abstract
The utility model discloses a kind of glare prevention structures, including aluminum substrate, the LED lamp bead being set on the aluminum substrate, the lens being mounted on above the LED lamp bead and the main body cooperated with the substrate, anti-dazzle arrangement is provided with above the lens, the anti-dazzle arrangement includes the thin-walled ring that certain height is formed above the lens, and the outer of the thin-walled ring places the thin-walled chaste tree for being provided with and the thin-walled ring being connected with the main body.The utility model forms an anti-dazzle thin-walled ring and thin-walled chaste tree above lens, and when human eye lamps and lanterns from the point of view of a certain range, lens light-emitting surface is blocked by the thin-walled ring and thin-walled chaste tree, to effectively prevent injury of the dazzle to human eye.
Description
Technical field
The utility model relates to lighting technical field more particularly to a kind of LED lamps with glare prevention structure.
Background technique
Dazzle refers in the visual field due to being not suitable for Luminance Distribution, or space or on the time there are extreme brightness contrast,
So that causing vision uncomfortable and reducing the visual condition of object visibility.The light sense that human eye can not adapt to is generated in the visual field
Feel, even it may cause detest, uncomfortable forfeiture legibility.There is excessively high brightness or front and back in a certain local area in the visual field
Excessive brightness change occurs.Dazzle is to cause the one of the major reasons of visual fatigue.
The existing anti-dazzle design of LED outdoor lamp is mostly sunk type, i.e., a circle certain altitude is designed more than light-emitting surface
Annular surface, to reach the light that people station will not be immediately seen LED sending in tilt angle.
This design solves glare problem to a certain extent, but this design causes glass capsulation face and lamps and lanterns to be open to be formed
Certain distance causes dust stratification or other dust not to remove naturally, and or formed lamps and lanterns cavity volume increase, formed siphon effect
It answers.
Utility model content
The technical problem to be solved by the utility model is to provide the LED lamps that one kind can effectively prevent dazzle.
In order to solve the above technical problems, the technical solution adopted in the utility model is: a kind of glare prevention structure, including aluminium base
Plate, the LED lamp bead being set on the substrate, the lens being mounted on above the LED lamp bead and with the aluminum substrate cooperate
Main body, be provided with anti-dazzle arrangement above the lens, the anti-dazzle arrangement, which is included in above the lens, to be formed
The thin-walled ring of certain height, the outer of the thin-walled ring place the thin-walled for being provided with and the thin-walled ring being connected with the main body
Chaste tree.
Further, the thin-walled ring is round or polygonized structure.
Preferably, setting is uniformly distributed there are three thin-walled chaste tree in outer place of the thin-walled ring.
Preferably, the substrate is aluminum substrate.
When LED emits beam, lens receive light and light are projected lamps and lanterns, if the not antiglare equipment, human eye is certain
Angle is the eyes that can be burnt by dazzling dazzle, and the utility model forms an anti-dazzle thin-walled ring and thin-walled above lens
Chaste tree, when human eye lamps and lanterns from the point of view of a certain range, lens light-emitting surface is blocked by the thin-walled ring and thin-walled chaste tree, thus effectively anti-
Injury of the dazzle to human eye is stopped.
The alternative traditional sunk type anti-dazzle design of the anti-dazzle design of the utility model, improves sunk type anti-dazzle dust stratification
And lamp luminescence cavity it is excessive the problems such as, can effectively improve lamps and lanterns dazzle, for miniaturization Design of Luminaires better thinking is provided.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
It clearly and completely describes, but does not constitute the limitation to scope of protection of the utility model.
Referring to shown in Fig. 1-5, a kind of glare prevention structure including substrate 1, the LED lamp bead being set on substrate 12, is mounted on
The lens 3 of 2 top of LED lamp bead and the main body 9 cooperated with substrate 1, specifically, substrate 1 in the embodiments of the present invention
Preferably aluminum substrate, aluminum substrate thermal diffusivity is good, and raw material is easy to get, and cost is relatively low;It is of course also possible to be other metal substrates or tool
There is the substrate of heat sinking function, here not to it into limiting very much;To enable main body 9 firmly to be combined with lens 3, main body 9 with
The structure mutually fastened is provided on lens 3.
The top of lens 3 is provided with anti-dazzle arrangement 4, is formed specifically, anti-dazzle arrangement 4 is included in above lens 3
The thin-walled ring 7 of certain height, outer in thin-walled ring 7 place the thin-walled chaste tree 8 for being provided with and thin-walled ring 7 being connected with main body 9.
Specifically, thin-walled ring 7 can for annulus or polygonized structure, such as triangle, square, hexagon etc.,
Thin-walled ring 7 and thin-walled chaste tree 8 are made of impermeable material, can be plastic cement etc..
Specifically, in thin-walled ring 7 be annulus in the embodiments of the present invention, its it is outer place to be uniformly distributed be provided with
Three thin-walled chaste trees 8, when thin-walled ring 7 is other shapes, when number of thin-walled chaste tree 8, can be configured according to the actual situation, such as
When square, four thin-walled chaste trees 8 are set.
When LED emits beam 6, lens 3 receive light and light 6 are projected lamps and lanterns, if not having antiglare equipment, human eye is at certain angle
Degree is the eyes that can be burnt by dazzling dazzle, and the utility model forms the thin-walled ring 7 and thin-walled of an anti-dazzle above lens 3
Chaste tree 8, when human eye lamps and lanterns from the point of view of a certain range, 3 light-emitting surface of lens is blocked by the thin-walled ring 7 and thin-walled chaste tree 8, to have
Effect prevents injury of the dazzle to human eye.
The alternative traditional sunk type anti-dazzle design of the anti-dazzle design of the utility model, improves sunk type anti-dazzle dust stratification
And lamp luminescence cavity it is excessive the problems such as, can effectively improve lamps and lanterns dazzle, for miniaturization Design of Luminaires better thinking is provided.
The above is preferred embodiments of the present invention, it is noted that for the ordinary skill of the art
For personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these are improved and profit
Decorations are also considered as the protection scope of the utility model.
