Description
Technical field
The present invention relates to a kind of optical element, particularly relate to a kind of optical element that reduces yellow dizzy phenomenon.
Background technology
In the backlight module of LED TV constantly constantly makes progress towards directions such as the large shape of size, lightweight quantification, thickness thin type, narrow frame design, high-performance, high-grade, low cost and environmental protection, how to promote as far as possible these numerous design considerations, become the development trend of LED TV backlight module in recent years.But, to heal become ripe in the situation that in liquid crystal display market, the lifting that can take into account usefulness becomes technology place the most competitive in liquid crystal display industry with reducing costs.In the middle of LED TV backlight module, be mainly divided into straight-down negative and side-light backlight, large scale thin type machine designs mainly with side-light backlight greatly at present, but area is larger, and the LGP using is more difficult for volume production, price is also higher, causes the more cost of the thin type machine of large scale to reduce.
Therefore, being returned to direct-type backlight, how making its demand that meets large scale thin type machine, and can solve with lower cost technology the technical problem of large scale thin type, is one of Research Emphasis of current industry.
And when the light emitting diode bright dipping of direct-type backlight in the past because light emitting diode contain fluorescent material in the corresponding optical element arranging, and can produce yellow dizzy phenomenon, make the visual effect of large scale thin type LED TV not good, cannot meet the need of market.
Summary of the invention
The object of the present invention is to provide a kind of optical element that reduces yellow dizzy phenomenon.
The present invention can reduce the optical element of yellow dizzy phenomenon, be applicable to corresponding installation a light emitting diode is set, this optical element that can reduce yellow dizzy phenomenon comprises an incidence surface and a bright dipping curved surface, this incidence surface comprises a par and an alcove, this alcove is positioned at the central authorities of this par, this light emitting diode arranges should alcove installing, and the medial surface of this alcove is roughened surface, this bright dipping curved surface and the opposing setting of this incidence surface and be arc-shaped surface.
The optical element that reduces yellow dizzy phenomenon of the present invention, the roughening degree that this alcove approaches this par is greater than the roughening degree near top.
The optical element that reduces yellow dizzy phenomenon of the present invention, this alcove approaches this par and is roughening, and this alcove is smooth surface near top.
The optical element that reduces yellow dizzy phenomenon of the present invention, the roughened surface of the medial surface of this alcove is atomization surface.
The optical element that reduces yellow dizzy phenomenon of the present invention, the roughened surface of the medial surface of this alcove is micro-structural roughened surface.
The optical element that reduces yellow dizzy phenomenon of the present invention, this bright dipping curved surface comprises that one is formed at central authorities and the recess towards this incidence surface depression, and one around this recess annular protrusion around.
Beneficial effect of the present invention is: the inner surface by this alcove forms roughened surface, therefore can improve bright dipping optical characteristics, dizzy Huang originally phenomenon is lowered, really reach the object of improving bright dipping optical characteristics, and the optical element that makes the present invention can reduce yellow dizzy phenomenon can more preferably be applied in large scale thin type LED TV.

Fig. 2 is a cutaway view, and an incidence surface and a bright dipping curved surface of this first preferred embodiment is described, the medial surface of this alcove is roughened surface;
Fig. 3 is a cutaway view, illustrates that this alcove that the present invention can reduce the second preferred embodiment of the optical element of yellow dizzy phenomenon approaches this par and is roughening, and this alcove is smooth surface near top;
Fig. 4 is a cutaway view, illustrates that this alcove roughened surface that the present invention can reduce the 3rd preferred embodiment of the optical element of yellow dizzy phenomenon is micro-structural roughened surface.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail.
Consult Fig. 1 and Fig. 2, the first preferred embodiment that the present invention can reduce the optical element 1 of yellow dizzy phenomenon is applicable to a corresponding light emitting diode 2 installation settings, and this optical element 1 that can reduce yellow dizzy phenomenon comprises an incidence surface 11, and a bright dipping curved surface 12.
This incidence surface 11 comprises a par 111 and an alcove 112, this alcove 112 is positioned at the central authorities of this par 111, this light emitting diode 2 is to installing setting by alcove 112, the medial surface of this alcove 112 is roughened surface, therefore, the light that this light emitting diode 2 sends is after the process medial surface of these alcove 112 roughenings, and it is more even that the optical characteristics of bright dipping will become, and effectively improves yellow dizzy phenomenon.
Illustrate further, in this first preferred embodiment, the roughened surface of the medial surface of this alcove 112 is atomization surface 113.
Therefore, bright dipping in the past has yellow dizzy phenomenon because of the relation of fluorescent material, and can make the visual effect of large scale thin type LED TV not good, cannot meet the need of market, after passing through again improvement of the present invention, can really improve the visual effect of large scale thin type LED TV.
The roughening degree that this alcove 112 approaches this par 111 is greater than the roughening degree near top.Focusing on of previous designs, due in the time that the lighting angle of this light emitting diode 2 is larger, yellow dizzy phenomenon is more serious, therefore, the present invention strengthens the roughening degree of this alcove 112 near par 111, to avoid this light emitting diode 2 to be subject to not good impact by the optical characteristics of the bright dipping on these alcove 112 tops.
This bright dipping curved surface 12 is with the opposing setting of this incidence surface 11 and be generally arc-shaped surface, and this bright dipping curved surface 12 comprises a recess 121 that is formed at central authorities and caves in towards this incidence surface 11, and one around this recess 121 annular protrusion 122 around.
In the second preferred embodiment of the present invention, coordinate and consult Fig. 3, this alcove 112 approaches this par 111 and is roughening, roughened surface is atomization surface 113, this alcove 112 is smooth surface near top, in order to keep this light emitting diode 2 good by the optical characteristics of the bright dipping on these alcove 112 tops.
In the 3rd preferred embodiment of the present invention, coordinate and consult Fig. 4, this alcove 112 approaches this par 111 and is roughening, and this alcove 112 is smooth surface near top, and roughened surface is micro-structural roughened surface 114.
In sum, effect that the present invention can reduce the optical element 1 of yellow dizzy phenomenon is to form roughened surface by the inner surface of this alcove 112, therefore can improve bright dipping optical characteristics, dizzy Huang originally phenomenon is lowered, really reach the object of improving bright dipping optical characteristics, and the optical element 1 that makes the present invention can reduce yellow dizzy phenomenon can more preferably be applied in large scale thin type LED TV, therefore really can reach the present invention's object.
