Abstract
The utility model discloses a light emitting diode of a prism surface. A transparent plane of the light emitting diode is made into a plurality of row-type lenses so that the light emitted by a chip of the light emitting diode is optically processed by the row-type lenses to produce corresponding optical effect so as to achieve the goals of enlarging lighting angles as well as gaining soft, being beautiful and eye-catching light.
Description
(1) technical field
The utility model relates to a class light-emitting diode, belongs to the LED device optical system
Technical field.
(2) background technology
Existing light-emitting diode generally adopts the convex lens caustic surface or adopts the planar light face promptly not have the processing of optics lens according to the application facet demand, is applied to mostly show and the indication field.Along with the manufacturing process and the device performance parameter of light-emitting diode improves constantly, light-emitting diode has begun as wide-angle indicator light and illuminating lamp, and the light-emitting diode of convex lens caustic surface that adopts at present or planar package constitutes indicator light and illuminating lamp, visible angle is little, light is not soft, and is not eye-catching as signal lamp.
(3) summary of the invention
The design the purpose of this utility model is at an above-mentioned not enough class LED device that proposes, the transparent surface of light-emitting diode is made multiple rib type form of lens, after the light that light-emitting diode chip for backlight unit is emitted is handled through rib type optics of lens, produce corresponding optical effect, to reach the expansion light angle, the purpose that light is soft, attractive in appearance, eye-catching.
As shown in the figure, led chip is fixed on the support, and as an electrode, another electrode is connected another utmost point of chip and support by spun gold.With epoxide-resin glue chip and electrode are encapsulated.Encapsulating mould designs on request, and making the exiting surface of encapsulation back light-emitting diode is prism-like.The design is transplanted to LED surface with multiple prism.As shown in drawings, taper shape, four prismatics, square body pinnacle, square body flat-top, five rib body pinnacles, five rib body flat-tops, hexagonal prism pinnacle and cruciate cylinder flat-top etc. are arranged.
The advantage of the utility model prism:
1. rib type lens place the transparent surface of light-emitting diode, change the light efficiency that of light-emitting diode
Really, enlarge the light angle of device, make the soft beauty of the light that sends.
2. the lamp decorative effect that is made of this prism improves greatly.
3. being skillfully constructed of the utility model device is reasonable in design, and be simple in structure, cheap,
Be fit to produce in enormous quantities, the device application field is extensive.

(5) specific embodiment
Below in conjunction with accompanying drawing one step of the utility model prism is set forth.
Accompanying drawing is listed profile and the structure chart of several prism facets LED.As shown in the figure, led chip is fixed on the support, and as an electrode, another electrode is connected another utmost point of chip and support by spun gold.With epoxide-resin glue chip and electrode are encapsulated.Encapsulating mould designs on request, and making the exiting surface of encapsulation back light-emitting diode is prism-like.The light that chip sends produces the lens optical effect through prism optical system, to reach the expansion angle, makes soft, attractive in appearance, the eye-catching purpose of light.The design is transplanted to LED surface with multiple prism.As shown in drawings, taper shape, four prismatics, square body pinnacle, square body flat-top, five rib body pinnacles, five rib body flat-tops, hexagonal prism pinnacle and cruciate cylinder flat-top etc. are arranged.
The utility model is skillfully constructed, and is reasonable in design, simple in structure, and the exiting surface of light-emitting diode is directly made prism, widened the application of light-emitting diode.
