Why are lenses and reflectors the soul of LED spotlights and other lighting fixtures? ||

With the rapid replacement of lighting products such as LED spotlights and LED downlights, their appearance and performance requirements are getting higher and higher, and optics can be described as the soul of lamps. What exactly do we use to shape the soul of LED spotlights? It must be the lens and the reflector! Today we are going to discuss these two species that support the soul of LED spotlights. Lenses. LED lenses are divided into primary and secondary lenses. What we generally call 'lens' refers to the secondary lens by default, that is, in the LED lamp beads. , COB and other light sources, and closely combined with it. According to different requirements, different lenses can be used to achieve the desired optical effect. So, how do the lens shape, light transmittance, and the visual effect of the lamp of the LED spotlight appear? Follow Optoelectronics to see how different scenes and different lamps meet the requirements of LED spotlight lenses? As shown in the figure, the side wall of this lens adopts free-form surface design, the near-beam surface is compound eyeball surface, the light output angle is adjustable, and the PC material can be used for the COB light source spotlight with the light-emitting surface diameter of mm. Its optical effective transmittance can be Up to %, uniform light output, good external viewing effect, especially suitable for some high-power spotlights with higher heat generation. In the picture, the lens adopts external free-form surface, near-beam surface, light-emitting surface and compound eyeball surface design. Both lenses are made of PC material, which has high temperature resistance. The light source can be a patch light source modular or COB light source, and the light output angle is °~ °Adjustable, uniform light output. When looking outside, the modular patch light source can be scattered by the compound eyeball surface, and the visual effects are COB-like, which expands the light source selectivity. In the picture, the lens adopts the external straight face scale and the compound eye design in the center of the light emitting surface. As shown in the figure, the two light sources have almost the same light output angle under the cooperation of the lens, and the light spot is uniform within the deviation °. It can be seen that a lens with a variety of light source designs not only highlights the optics of the lens design, but also reflects the aesthetics of the lighting product design. It saves a lot of design time for luminaire manufacturers and can effectively shorten the development of luminaires. Time is more attractive to customers. , Reflective cup usually LED light source light angle is about °, in order to achieve the desired optical effect, lamps and lanterns sometimes use reflectors to control the light distance, light area, light spot effect. The optical effect of the lens and the reflector, and the effect of the application of the different lens generally has no secondary spot, and the light shape is more beautiful. Because of the TIR design, the light output efficiency is relatively high. For example, optoelectronics prefer to use lens solutions to design lamps, which can be made more compact! The reflector is used in this occasion. The effect is quite beautiful! This is not easy to achieve with the lens! It can be seen that the soul of an LED spotlight must have a reasonable combination of lens and reflector to make the optics shine to a new height! In the direction of satisfying aesthetics and practicality, a high light transmittance and uniformity of light transmission are still the mainstream of the design, and it is also a high-quality LED spotlight, LED downlight, floodlight, street light and other lighting fixtures.
