With the rapid development of LED industry, the accompanying LED lenses are constantly washed out. With the continuous entry of LED industry, and the special requirements of different places and customers, the demand for optical effect is also quite different, the future development of LED lens will be more detailed and personalized. Relative to LED spotlights, in the fierce competition in the LED market environment, how to improve product competitiveness is the focus of factory research. Therefore, we need LED spotlight to design a high transmittance, high grade, low cost lens.
With the continuous upgrading and integration of LED industry, the speed of LED spotlight products replacement is also very fast. LED lamp lens development is rapid follow-up, from the overall market, consumers are most concerned about is the visual effect of lighting and light effect, so the design of LED lens lamp must meet three requirements: one is the LED lens shape is novel, fashionable and beautiful; two is the effective transmission rate of LED lens; three is the visual effect of LED lens and lamp collocation. Through the above three aspects of the demand point, the current market spotlight in the application of common LED lens design, there are three kinds, the following are briefly explained.
Design 1, LED lens side wall of a free surface, nearly smooth eye bead surface, light angle adjustable 250-600, generally used PC, PMMA material, also can be used for maximum COB light source lamp surface diameter of 14mm, through the lens effective maximum transmittance can reach about 95%.
2, LED lens using external face armor, a design of smooth eye center.
3, LED lens adopts external freeform surface, near smooth surface and smooth surface compound eye bead surface design.
The latter two kinds of LED lens design usually use PC material, high temperature resistance, the LED light source can use SMD light source module or COB light source, the light angle is adjustable 300-600, the light effect is even. When the light source is outside, the modular patch light source can be broken by the compound eye bead surface, the visual effect is COB, and the flexibility of the light source is more flexible.
In addition, from the high-end demand and lighting manufacturing cost considerations, the design of a LED lens, you can match a variety of light sources, increase the versatility of the product. Reasonable collocation eye bead surface and external scales used in lighting lens, not only to optimize the overall lighting visual appearance, can effectively solve the problem of frequent design of different light sources matching different lens, further saving lamp design and manufacturing time, effectively shorten the development cycle of the whole light.
Now LED has not only the basic function of the lens to design light effect, but also with the development trend of lighting development to the appearance and common direction, so as to improve the effective light lens transmittance, spot uniformity, sharing, appearance and direction of development will be the focus of concern about the future of the designers!
