Abstract
The invention relates to the field of illumination and discloses a non-glare LED lamp which comprises a lampshade, a plurality of LED beads and lenses corresponding to the LED beads. The light emitting surface of the lampshade is provided with at least one circle of reflection cup corresponding to the LED beads. Each LED corresponds to the corresponding reflection cup and the corresponding lens. Light emitted by the LED beads is gathered through the corresponding lenses and then is evenly emitted out after being reflected by the inner walls of the corresponding reflection cups. According to the non-glare LED lamp, even light emitting can be achieved without increasing the distance between the beads and the lampshade, devices such as a power source can be installed through a spare space in the center of an LED lamp panel, and accordingly the thickness of the lamp can be greatly decreased; the lighting effect loss is reduced along with the decreasing of the distance between the beads and the lampshade; and relatively speaking, due to the facts that the LED beads are distributed more dispersedly, and the diffusion angle of light is limited in a certain range, the glare phenomenon can be well eliminated, and discomfort of human eyes is avoided.
Description
Technical field
The present invention relates to field of illuminating lamps, more particularly, to a kind of LED for eliminating dazzle.
Background technology
With the development of technology, LED lamp as a kind of energy-efficient lighting apparatus be widely used in family, hotel,
The occasions such as school, retail shop, office building.At present the structure of LED lamp generally includes lampshade and LED as shown in Figure of description 1
Plate, wherein lampshade are diffusion shell, and the light that LED lamp panel sends is projected through diffusion shell and from the exiting surface of diffusion shell, in order that
Go out light to be more uniformly distributed, need to be spaced a distance between LED lamp panel and lampshade (as the lampshade in figure adopt the lampshade of arc with
Pull open the distance with lamp plate), this structure will increase the whole height of light fixture, be unfavorable for realizing the lightening of light fixture, while
Also result in light efficiency loss；Additionally, the LED lamp panel of existing light fixture generally adopts the organization plan for being covered with LED lamp bead, however as
Diffusion of the concentration and lampshade of light source to light, this kind of fitting structure is easy to produce the phenomenon of dazzle, gives people eye band
Come uncomfortable.
The content of the invention
In order to overcome the deficiencies in the prior art, the present invention to provide a kind of free from glare LED lamp cover.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of free from glare LED, including lampshade and some LED lamp beads, also including the lens of the correspondence LED lamp bead, institute
State on the exiting surface of lampshade the reflector that correspondence LED lamp bead is provided with least one circle, each LED with reflector described in one and
Lens correspondence, the light that each LED lamp bead is sent is converged via the correspondence lens, then by the correspondence reflector
Uniformly project after wall reflection.
Used as the further improved procedure of such scheme, the reflector is rounded or distributed rectangular.
Used as the further improved procedure of such scheme, the reflector is hemispherical, or by the inclined side wall of polylith
Around forming, the reflector gradually expands along light direction.
Used as the further improved procedure of such scheme, the reflector is inclined by four pieces, six pieces or eight pieces with equal
The side wall of rake angle is surrounded and formed.
Used as the further improved procedure of such scheme, the lampshade is provided with the reflector of multiple concentric, and
Corresponding LED lamp bead and lens.
As the further improved procedure of such scheme, the reflecting surface of the reflector inwall shape Jing after fine grinding by plastic cement
Into reflectance factor is not less than 85%.
Used as the further improved procedure of such scheme, the lens are coated in the outer of the LED lamp bead along light direction
Side, and positioned at the bottom of the reflector.
As the further improved procedure of such scheme, including the lamp plate of annular and annular lens board, on the lamp plate
The LED lamp bead is distributed uniformly and circumferentially, the lens have been distributed uniformly and circumferentially on the lens board, it is described
Lamp plate and lens board are sequentially arranged in the side of the lampshade dorsad exiting surface along light direction.
As the further improved procedure of such scheme, including installing rack and lamp socket, lamp socket is used for fastening lampshades, and it is in the back of the body
Be provided with step surface to the side of lampshade, be provided with flange above step surface, the two ends of installing rack be plugged on step surface and flange it
Between, which is provided with some installing holes.
Enclose as the further improved procedure of such scheme, including EVA, base is provided with annular groove in the side of dorsad lampshade,
EVA circles are embedded within annular groove.
The invention has the beneficial effects as follows：
Need not increase that the distance between lamp bead and lampshade similarly can realize uniformly going out the electrical parts such as light, power supply can be with profit
Installed with the clearance spaces at LED lamp panel center, such that it is able to the thickness for greatly reducing light fixture, realize light fixture flattening,
It is lightening；Meanwhile, with the diminution of distance between lamp bead and lampshade, light efficiency loss is also reduced therewith, i.e., only need less lamp bead
Just same illuminating effect can be realized, or lamp bead quantity has more preferable illuminating effect when identical；Further, since in the present invention
LED lamp bead distribution relatively more disperses, while the diffusion angle of light is also defined within certain angle, therefore can be fine
Elimination dazzle phenomenon, it is to avoid cause the discomfort of human eye.
