For the dazzling problem of LED, there is oneself solution in current each producer, have and adopt wire drawing PC face shield, have and adopt frosted face shield, have and adopt special phosphor material powder etc., but these methods are all cured the symptoms, not the disease, wire drawing face shield can be eliminated dazzling, but hot spot phenomenon is more serious, and slightly slot mesh eyeball is easily tired the time under this lamp for people, under this lamp, use eye if long-time, also can cause eyes astigmatism; And adopting frosted and milky face shield to light loss too greatly, effect is too poor.
In addition, LED light emission direction is very strong, about about 120 degree of irradiating angle, is easy to produce lighting blind zone or hot spot.Particularly use reflection Lamp cup to carry out the light fixture of optically focused, this phenomenon is more outstanding.Fig. 1 and Fig. 2 show schematically show the illuminating effect of the LED lamp of existing light-focusing type.As shown in the figure, the light of reflector oral area is gathered by reflector, forms surround A, and it is peripheral that the light bottom reflector is reflected onto effective lighting district A, forms secondary surround B.Light in secondary surround B is comparatively mixed and disorderly, or color Huang distortion partially, or have significantly highlighted and high dark space, or both, thus the light in secondary surround B does not have use value substantially, also can affect the illuminating effect of light fixture even in some cases.
Summary of the invention
The object of this invention is to provide a kind of combined LED reflector, secondary surround can be eliminated, improve light efficiency and the lamp lighting effect of LED light source thus.
According to an aspect of the present invention, provide a kind of combined LED reflector be arranged on LED light source, comprise Lamp cup and light-controlling device, LED light source is positioned at bottom Lamp cup, Lamp cup inwall has fully reflecting surface, light-controlling device is located in Lamp cup, light-controlling device has the first distribution surface and the second distribution surface, first distribution surface is the plane parallel with LED light source and close LED light source, second distribution surface is curved surface or multiple surface assembled face and away from LED light source, light-controlling device adopts transparent material manufacture, a light part for first distribution surface of LED light source directive light-controlling device is reflected onto fully reflecting surface, another part passes light-controlling device and refracts to fully reflecting surface by the second distributor.
Adopt the combined LED reflector of above technical scheme, employ a transparent light-controlling device be positioned at bottom Lamp cup a part of light bottom Lamp cup is distributed, secondary surround is formed after avoiding it to shine directly into the fully reflecting surface of Lamp cup, secondary surround can be eliminated thus, improve light efficiency and the lamp lighting effect of LED light source thus.
In some embodiments, the second distribution surface is through frosted process.Thus, the light carrying out distributing via the second distribution surface is more even.
In some embodiments, the first distribution surface is through frosted process.Thus, the light carrying out distributing via the first distribution surface is more even.
In some embodiments, the first distribution surface also has combination reflective surface.Combination reflective surface is made up of the multiple hemisphere be evenly arranged on the first distribution surface or plate polyhedron.Thus, the light carrying out distributing via the first distribution surface is more even.
In some embodiments, Lamp cup oral area is provided with light-passing board, and light-controlling device is connected with light-passing board by column.Column is directly installed on light-passing board, easy for removal and installation.For different Lamp cups or different illumination occasions, advantage may need to regulate the position of light-controlling device in Lamp cup to reach best effect, utilizes column to install, accessory supporting when can reduce manufacture.
In some embodiments, light-controlling device is connected with column by screw thread, and column is connected with light-passing board by screw or bolt.Thus, the dismounting of light-controlling device and easier for installation.
In some embodiments, column is one and is installed vertically on the center of light-passing board.The light at light-passing board center is generally vertical with light-passing board, and column just can parallel with the light of its position thus, and then can reduce the impact of shade on illuminating effect of column to greatest extent.
In some embodiments, light-controlling device is connected with Lamp cup by support.
In some embodiments, support is positioned at bottom or the oral area of Lamp cup.
In some embodiments, the second distribution surface is the combinatorial surface that the combinatorial surface that is made up of multiple plane or multiple curved surface form.The combinatorial surface of the second distribution surface can match with the combinatorial surface of fully reflecting surface, can reach best distribution effects thus.
In some embodiments, the second distribution surface is hemisphere face.Thus, the distribution effects of the second distribution surface is better.
