Abstract
The utility model discloses a reflecting cup for an LED light source. The reflecting cup for the LED light source comprises a reflecting cup body, a first port and a second port, wherein the first port and the second port are formed in the two ends of the reflecting cup body, the inner wall of the reflecting cup body is a free-form surface, and the first port and the second port are both of a circular shape. Due to the fact that the free-form surface serves as the inner wall of the reflecting cup body, light emitted by the LED light source is reflected by the inner wall of the reflecting cup body so that emergent rays with good condensation performance, high evenness and good illumination effect can be obtained and the reflecting cup for the LED light source can be widely used in the illumination industries.
Description
Technical field
The utility model relates to lighting field, particularly a kind of reflector for LED light source.
Background technology
At present, LED light source, because of the characteristic such as it is low in energy consumption, volume is little, the life-span is long and brightness is high, has been widely applied to various fields, 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, be all that LED light source is combined with reflector, thereby reach specific lighting requirement.Yet not only bore is large for present most of reflector, light-gathering 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 is to provide that a kind of light-gathering 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:
A kind of reflector for LED light source, comprise the first port and second port at reflector cup and reflector cup two ends, and the inwall of described reflector cup is free form surface, and described the first port and the second port are circle.
Further, described free form surface be by free curve by rotatablely moving, the curved surface that forms after banking motion or offset movement.
Further, described free curve meets the following conditions:
Wherein, A
1, A
2, A
3And A
4For constant.
Further, described free curve meets the following conditions:
Further, the diameter of described the first port is 1.0 ~ 2.4mm, and the diameter of described the second port is 3.5 ~ 5.0mm.
Further, the inside wall height of described reflector cup is 1.5 ~ 2.5mm.
The beneficial effects of the utility model are: a kind of reflector for LED light source of the present utility model, adopt the inwall of free form surface as the reflector cup, the light that LED light source can be sent after reflection, obtains that light-gathering is good, the uniformity is high and the emergent ray of good illumination effect at the inwall of reflector cup.
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 a kind of reflector for LED light source of the present utility model.
The specific embodiment
The utility model provides a kind of reflector for LED light source, comprises the first port and second port at reflector cup and reflector cup two ends, and the inwall of described reflector cup is free form surface, and described the first port and the second port are circle.
Be further used as preferred embodiment, described free form surface be by free curve by rotatablely moving, the curved surface that forms after banking motion or offset movement.
Be further used as preferred embodiment, described free curve meets the following conditions:
Wherein, A
1, A
2, A
3And A
4For constant.X is the x axial coordinate value of two-dimensional coordinate system axle, and y is corresponding y axial coordinate value, and the y axle is parallel with optical axis.
Be further used as preferred embodiment, described free curve meets the following conditions:
Be further used as preferred embodiment, the diameter of described the first port is 1.0 ~ 2.4mm, and the diameter of described the second port is 3.5 ~ 5.0mm.
Be further used as preferred embodiment, the inside wall height of described reflector cup is 1.5 ~ 2.5mm.
Below in conjunction with Fig. 1, a specific embodiment of the present utility model is described:
A kind of reflector for LED light source, comprise the first port 2 and second port 3 at reflector cup 1 and reflector cup two ends, and the inwall of reflector cup 1 is free form surface, and the first port 2 and the second port 3 are circle.Free form surface is obtained by rotatablely moving by free curve 4, and in the present embodiment, free form surface is to be rotated and obtain by the optical axis 5 around reflector cup 1 by free curve 4, and free curve meets the following conditions:
Wherein, A
1, A
2, A
3And A
4For constant.X is the x axial coordinate value of two-dimensional coordinate system axle, and y is corresponding y axial coordinate value, and the y axle is parallel with optical axis 5, and namely here, the x axle is the residing reference axis of arbitrary radius of the circular section of the first port 2.The diameter of the first port 2 is 1.0 ~ 2.4mm, and the diameter of the second port 3 is 3.5 ~ 5.0mm, and the inside wall height of reflector cup 1 is 1.5 ~ 2.5mm.While using reflector, the first port 2 is arranged near the LED light source place, namely the first port 2 places are light incident end, and the second port 3 places are the beam projecting end, LED light source can be arranged on the first port 2 centers.For free curve being done further restriction, can be to constant A
1, A
2, A
3And A
4Carry out assignment, make A
1=0.58395, A
2=0.29009, A
3=0.04537, A
4=0.67611, the defining equation that obtains free curve is:
This shows, a kind of reflector for LED light source of the present utility model, for light that LED light source is sent after the first port 2 incidents of reflector, obtain the emergent ray of the high and good uniformity of light-gathering from the second port 3, only need by selecting suitable free curve equation and limiting accordingly parameter, and then this free curve is rotated motion, banking motion or offset movement, and the free form surface that will obtain gets final product as the inwall of reflector cup 1.Certainly, here, the inwall of reflector cup 1 need carry out polishing or coating film treatment.After the light that adopts reflector of the present utility model to send LED light source carried out optically focused, rising angle was generally less than 30 degree.
More than that better enforcement of the present utility model is illustrated, 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 without prejudice to the utility model spirit, the modification that these are equal to or replacement all are included in the application's claim limited range.
