Abstract
The utility model discloses a reflecting cup for LED light sources. The reflecting cup for the LED light sources comprises a reflecting cup body, a reflecting cup bottom face located at one end of the reflecting cup body and a reflecting cup opening end located at the other end of the reflecting cup body. The reflecting cup bottom face is an ellipse, the inner wall of the reflecting cup body is formed by a Bethel curved surface, and the reflecting cup opening end is a circle. According to the reflecting cup for the LED light sources, the ellipse shape is adopted by the reflecting cup bottom face and the Bethel curved surface is adopted as the inner wall of the reflecting cup body, the light emitted by a plurality of LED light sources mounted on the reflecting cup bottom face can be reflected through the inner wall of the reflecting cup body, emergent rays with good light condensing performance, high evenness and good illumination effects are obtained, and the reflecting cup for the LED light sources can be widely applied to illumination industries.
Description
Technical field
The utility model relates to lighting field, particularly relates to a kind of reflector that is applicable to the plurality of LEDs light source.
Background technology
At present, led light source is low in energy consumption because of it, volume is little, the life-span is long and characteristic such as brightness height, has been widely applied to various fields, for example fields such as indoor and outdoor lighting, back lighting, medical treatment, traffic and plant production.In a lot of application scenarios of led light source, all be that led light source is used in combination with reflector, particularly the plurality of LEDs light source is used in combination with reflector, thereby reaches specific lighting requirement.Yet not only bore is big for present most of reflector, optically focused is poor, and uniformity is low, causes illuminating effect very poor.
The utility model content
In order to solve above-mentioned technical problem, the purpose of this utility model provides that a kind of optically focused that is applicable to the plurality of LEDs light source is good, uniformity is high and the reflector that is used for led light source of good illumination effect.
The technical scheme that its technical problem that solves the utility model adopts is:
The reflector that is used for led light source, the reflector openend that comprises the reflector cup, is in the reflector bottom surface of reflector cup one end and is in the reflector cup other end, described reflector bottom surface is oval, the inwall of described reflector cup is made of bezier surface, and described reflector openend is circular.
Further, the minor axis axial length of described reflector bottom surface is 0.5 ~ 1.5mm, and the major axis axial length of described reflector bottom surface is 1.0 ~ 2.5mm, and the diameter of described reflector openend is 3.5 ~ 5.0mm.
Further, the inside wall height of described reflector cup is 1.5 ~ 2.5mm.
Further, the light path of the light that described led light source sends is: from the outgoing of reflector openend, and the angle between the vertical line of emergent ray and reflector bottom surface is spent less than 30 through the inwall of reflector cup reflection back.
The beneficial effects of the utility model are: the reflector for led light source of the present utility model, oval in shape is adopted in the reflector bottom surface, and adopt bezier surface as the inwall of reflector cup, the light that the plurality of LEDs light source that is installed in the reflector bottom surface can be sent obtains that optically focused is good, the uniformity is high and the emergent ray of good illumination effect after the inwall of reflector cup is through reflection.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the schematic diagram of the reflector for led light source of the present utility model.
The specific embodiment
The utility model provides the reflector that is used for led light source, the reflector openend that comprises the reflector cup, is in the reflector bottom surface of reflector cup one end and is in the reflector cup other end, described reflector bottom surface is oval, the inwall of described reflector cup is made of bezier surface, and described reflector openend is circular.
Be further used as preferred embodiment, the minor axis axial length of described reflector bottom surface is 0.5 ~ 1.5mm, and the major axis axial length of described reflector bottom surface is 1.0 ~ 2.5mm, and the diameter of described reflector openend is 3.5 ~ 5.0mm.
Be further used as preferred embodiment, the inside wall height of described reflector cup is 1.5 ~ 2.5mm.
Be further used as preferred embodiment, the light path of the light that described led light source sends is: from the outgoing of reflector openend, and the angle between the vertical line of emergent ray and reflector bottom surface is spent less than 30 through the inwall of reflector cup reflection back.
Below in conjunction with Fig. 1 a specific embodiment of the present utility model is described:
The reflector that is used for led light source, the reflector openend 3 that comprises reflector cup 1, is in the reflector bottom surface 2 of reflector cup 1 one ends and is in reflector cup 1 other end, reflector bottom surface 2 is oval, its minor axis axial length is 0.5 ~ 1.5mm, major axis axial length is 1.0 ~ 2.5mm, and minor axis axial length is less than major axis axial length; The inwall of reflector cup 1 is made of bezier surface; Reflector openend 3 is circular, and its diameter is 3.5 ~ 5.0mm.Reference numeral 4 represents the vertical line of reflector bottom surface 2 among the figure, and the light path of the light that led light source sends is: from 3 outgoing of reflector openend, and the angle between the vertical line 4 of emergent ray and reflector bottom surface 2 is spent less than 30 through the inwall of reflector cup reflection back.
The plurality of LEDs light source is installed on the oval-shaped reflector bottom surface 2, for example be installed on the major axis or minor axis of reflector bottom surface 2, when the design reflectivity cup, bezier surface inwall to reflector cup 1 designs, make and be installed in the center of reflector bottom surface 2 and the light that other local led light source sends, through the emergent ray that obtains after the reflective cup reflects spot center that shadow surface forms all with same of being centered close to of reflector bottom surface 2 on, therefore, the spot center that reflector of the present utility model can make the light of plurality of LEDs light source form is in the center of shadow surface, and optically focused is good and the uniformity is high.When particularly this reflector being used for the led light source of many different colours is installed, only need to regulate the energy of every LEDs light source, just can make the color that finally shines on the shadow surface even, piebald can not occur.
This shows, reflector for led light source of the present utility model, adopt oval-shaped reflector bottom surface 2, and the bezier surface of the inwall that constitutes reflector cup 1 designed, the light that the led light source that is installed in diverse location on the reflector bottom surface 2 can be sent gathers the same center on the shadow surface, optically focused height and good uniformity are applicable to the situation of using the plurality of LEDs light source.Certainly, here, the inwall of reflector cup 1 need polish or coating film treatment.
More than be that preferable enforcement of the present utility model is specified, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite of the utility model spirit, the modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
