Abstract

An LED (Light Emitting Diode) light mixing and focus adjusting device comprises an LED base plate and a plurality of LED light emitting sources, wherein the LED light emitting sources are arranged on the LED base plate, a light reflecting bowl is arranged on each LED light emitting source, and a condenser lens is arranged above each light reflecting bowl; and a distance between each condenser lens and each light reflecting bowl is adjusted by a distance adjusting device. Light emitted by the LED light emitting sources is first reflected by the light reflecting bowls. As the light from the LED light emitting sources can be reflected by the light reflecting bowls to a greater extent, the utilization rate of the light sources is higher. A focus can be changed through the adjustment of the distances between the condenser lens and the light reflecting bowl. When the condenser lenses are far from the light reflecting bowls, the light outgoing angle of the light mixing and focus adjusting device is small. When the condenser lenses are adjacent to the light reflecting bowls, the light outgoing angle of the light mixing and focus adjusting device is large. The LED light mixing and focus adjusting device has the advantages of uniform light mixing, high utilization rate in the light sources, simple structure and low cost and price.

Description

A kind of LED mixed light focus control
Technical field
The utility model relates to the LED lighting field, especially a kind of LED mixed light focus control.
Background technology
The LED lamp owing to have rich color, advantages such as the life-span is long, luminous efficiency is high, energy-conserving and environment-protective are widely used in the daily life, because led chip mainly is red, blue and green, therefore in the middle of practical application, in order to obtain the illumination of wideer colour gamut, need carry out mixed light to the LED light emitting source usually.The technological difficulties of mixed light are the uniformity of mixed light, existing mixed light mainly relies on lens to carry out, as Chinese patent, publication number is a kind of LED optical system of CN102287647 and utilizes the LED optical system to carry out the method for mixed light, zoom that the LED optical system comprises LED, collector lens and zoom lens successively by radiation direction; On the collector lens exiting surface by the first lenticule group of being formed by first lenticule more than two; Described varifocal mirror comprises the varifocal mirror body and is located at the second lenticule group on the varifocal mirror body, and the second lenticule group is made up of second lenticule, and second lenticule is equal with the first lenticule quantity on the collector lens and the position is corresponding.The method of its mixed light, zoom is: first mixed light, form the small light spot point that color is positioned at the first lenticule group back uniformly then, and last, by varifocal mirror the small light spot point is carried out zoom, thereby obtain a hot spot.Though above-mentioned mixed light system also can reach the purpose of even light mixing, its complex structure, cost is higher.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of LED mixed light focus control, even light mixing not only, and light source utilization rate height, and also simple in structure, cost price is low.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of LED mixed light focus control, comprise LED substrate and a plurality of LED light emitting sources of being located on the described LED substrate, each LED light emitting source is equipped with reflector, and each reflector top is provided with collector lens; Distance between described collector lens and the described reflector is adjusted by distance adjusting means.The light that the LED light emitting source sends at first reflects through reflector, and reflector can be to a greater extent reflects the light of LED light emitting source, makes its light source utilization rate higher.Light through the reflector reflection is convergeed on the collector lens, by collector lens light is carried out optically focused again, and the adjacent LED light emitting source mixes by the emergent light of reflector and collector lens, thereby reaches the purpose of mixed light and optically focused.By adjusting the distance between collector lens and the reflector, can change focal length, when collector lens during away from reflector, the rising angle of mixed light focus control is less; When collector lens when the reflector, the rising angle of mixed light focus control is bigger.The utility model is even light mixing not only, light source utilization rate height, and also simple in structure, cost price is low.
As improvement, described distance adjusting means is connected with described collector lens.
As improvement, described distance adjusting means comprises screw mandrel, with described screw mandrel nut engaged with drive the lead screw motor of described screw mandrel rotation, and described nut is connected with described collector lens.
As improvement, described LED light emitting source is single LEDs chip, a plurality of led chip or LED module.
As improvement, described LED light emitting source is monochromatic single-chip or polychrome multi-chip.
As improvement, described collector lens is Fresnel collector lens or sphere collector lens.
As improvement, described reflector is located at described LED light emitting source top, is provided with the gap between the exiting surface of reflector bottom and LED light emitting source.
The beneficial effect that the utility model compared with prior art brings is:
The light that the ED light emitting source sends at first reflects through reflector, and reflector can be to a greater extent reflects the light of LED light emitting source, makes its light source utilization rate higher.Light through the reflector reflection is convergeed on the collector lens, by collector lens light is carried out optically focused again, and the adjacent LED light emitting source mixes by the emergent light of reflector and collector lens, thereby reaches the purpose of mixed light and optically focused.By adjusting the distance between collector lens and the reflector, can change focal length, when collector lens during away from reflector, the rising angle of mixed light focus control is less; When collector lens when the reflector, the rising angle of mixed light focus control is bigger.The utility model is even light mixing not only, light source utilization rate height, and also simple in structure, cost price is low.
Description of drawings
Fig. 1 is that collector lens is away from the schematic diagram of reflector.
Fig. 2 is that collector lens is near the schematic diagram of reflector.
The specific embodiment
The utility model is described in further detail below in conjunction with Figure of description.
As shown in Figure 1, 2, a kind of LED mixed light focus control, comprise LED substrate 1 and a plurality of LED light emitting sources 2 of being located on the described LED substrate 1, each LED light emitting source 2 is equipped with reflector 3, each reflector 3 top is provided with collector lens 4, and the distance between described collector lens 4 and the described reflector 3 is adjusted by distance adjusting means.Described LED light emitting source 2 is single LEDs chip, a plurality of led chip or LED module; Described LED light emitting source 2 is monochromatic single-chip or polychrome multi-chip.Described reflector 3 is located at described LED light emitting source 2 tops, is provided with the gap between the exiting surface of reflector 3 bottoms and LED light emitting source 2.Described collector lens 4 is Fresnel collector lens 4 or sphere collector lens 4, and all collector lenses 4 interconnect and are integral, and makes its structure, assembling and manufacturing process simpler.Described distance adjusting means comprises screw mandrel 5, with described screw mandrel 5 nut engaged 6 with drive the lead screw motor 7 of described screw mandrel 5 rotations, described nut 6 is connected with described collector lens 4; 5 rotations of lead screw motor 7 drive screw mandrels, the rotation of screw mandrel 5 moves up and down nut 6 relative screw mandrels 5, and owing to nut 6 is connected with collector lens 4, thereby the lifting of nut 6 drives collector lens 4 one liftings, thereby changes the distance of collector lens 4 and reflector 3.
