Abstract
The utility model relates to a lighting luminaire for solving the problem of poor light concentration of an existing high-power LED lamp and provides a novel high-power LED spotlight which comprises an LED luminous body, wherein an optical fiber panel is bonded on the light-emitting surface of the LED luminous body, the thickness of the optical fiber panel is 1-1.5mm, the fiber diameter is 50 mu m, an optical shadowless adhesive layer is coated between the light-emitting surface of the LED luminous body and the optical fiber panel for carrying out coupling and bonding, and the thickness of the adhesive layer is 20-30 mu m. The high-power LED spotlight adopts the optical fiber panel as a high-power LED light source light concentration body, thereby being convenient for controlling the divergence angle of a high-power LED light source between 60 degrees and 70 degrees, improving the light collection efficiency, leading the light concentration of the LED lamp to become simple and easy to operate, reducing the volume of the whole lamp and reducing the weight.
Description
Technical field
The utility model relates to a kind of lighting, is specially a kind of great power LED spotlight.
Background technology
High-powered LED lamp is widely used in light, video display industry.Reason owing to manufacture view, the LED illuminator is a rectangle, as shown in Figure 1, lighting angle is between 150 °-160 °, it is a kind of area source of divergence form, prior art is to use the optically focused lampshade in the optically focused process, but has following shortcoming: (1) area source optically focused is poor, and focal length is difficult to hold during optically focused; (2) because lighting angle is big, the snoot volume is increased, weight increases, and light gathering efficiency descends.
Summary of the invention
For solving the problem of existing high-powered LED lamp optically focused difference, the utility model provides a kind of novel large-power LED spotlight.
A kind of great power LED spotlight described in the utility model comprises the LED illuminator, is bonded with fibre faceplate on the light-emitting area of LED illuminator.The utility model be with fibre faceplate as the high-power LED light source condensing body, be to utilize the characteristics that the fibre faceplate volume is little, collection efficiency is high, loss is little and dispersion angle is little, improve the collection efficiency of great power LED spotlight.
In order further to improve light gathering efficiency, the thickness of fibre faceplate is 1～1.5mm, and the silk footpath is 50 μ m.
In order not influence the optical effect of LED lamp when bonding LED illuminator and the fibre faceplate, scribble between the light-emitting area of LED illuminator and the fibre faceplate and carry out lotus root and close bonding optics and do not have shadow glue glue-line, optics does not have light transmittance 〉=93% of shadow glue, and bondline thickness is 20-30 μ m.
Compare with the snoot of available technology adopting, the utility model adopts fibre faceplate can be controlled at the high-power LED light source angle of divergence between 60 °-70 ° easily as the high-power LED light source condensing body, collection efficiency improves, make the optically focused of LED lamp become simple, easy to operate, make whole light fixture volume reduce weight saving.
Description of drawings
Fig. 1 is traditional LED lamp schematic diagram.
Fig. 2 is equipped with the great power LED spotlight of fibre faceplate for the utility model.
Among the figure, the 1-LED illuminator; The 2-fibre faceplate.
The specific embodiment
A kind of great power LED spotlight described in the utility model as shown in Figure 2, comprises LED illuminator 1, is bonded with fibre faceplate 2 on the light-emitting area of LED illuminator 1.The thickness of fibre faceplate 2 is 1～1.5mm, and the silk footpath is 50 μ m.Scribbling optics between the light-emitting area of LED illuminator 1 and the fibre faceplate 2 does not have shadow glue glue-line and carries out lotus root and close bonding.Coupling agent optics does not have light transmittance 〉=93% of shadow glue, and bondline thickness is 20-30 μ m.
The concrete preparation method of the utility model is: make the identical fibre faceplate of a block size according to great power LED illuminator light-emitting area area, and complete white, do not insert the absorption silk, guarantee that its transmitance is about 90%.Dripping a little optics for preparing at great power LED illuminator light-emitting area does not have shadow glue, again fibre faceplate is close to its surface, each limit alignment, make intermediate gelatine layer even as far as possible, no bubble between the bondline thickness control 20-30 μ m, glues after uviol lamp just solidifies and the curing of middle temperature back gets final product.Coupling agent can adopt two component optics of light transmittance 〉=93% of UV ultraviolet photo-curing glue research department, Shanghai production not have shadow glue.
