LED spot light fittings - lens design

    As everyone knows, LED downlight product turnover speed is be struck dumb. The development of LED spot light fittings - lens is also make a spurt of progress. But overall, the attention on the market or lamps visual effect and light effect, so the lens design to meet the three requirements: one is the novel lens shape; two is effective and transparent lens rate; three is the visual effect of lens and lamp fitting. According to the above three requirements, there are three main lens design in the common market:
    First, the lens side by free surface design, the light exit surface uses compound eye design, light angle adjustable 250-600, the general use of PC material, can be used for the COB light source lamp surface diameter 14mm, the effective optical transmittance can reach to maximum 94%.
    The second lens using external face scales, the light exit surface center uses compound eye design. The third lens using external surface, nearly smooth, The light exit surface uses compound eye design.
    The second and third lens generally use PC material, high temperature tolerance, the light source can be used modular SMD light source or COB light source, a light adjustable 300-600, uniform light output. Apparent, SMD light source can scattering by compound eyes , visual effect is similar to COB. Expand the light source of selective.
    Thus, LED spot light lens design has been gradually to aesthetics and versatility direction, how to improve the effective transmittance of the lens spotlights, spot uniformity, universal design will become mainstream.
