Back-lit energy-saving led panel light t-bar keel type occupies an important position in the field of modern lighting with its high efficiency, environmental protection and long life. However, the glare problem has always been one of the key factors affecting the lighting quality of LED panel lights. In order to improve the visual comfort of users, reducing glare has become an important task in the optical design of LED panel lights.
Glare mainly comes from the strong light of the LED light source directly irradiating the human eye, causing visual discomfort or visual impairment. In LED panel lights, the glare problem is particularly prominent because the luminous area of the panel light is relatively large and the light source distribution is relatively concentrated. In order to effectively reduce glare, the optical design of LED panel lights needs to start from multiple aspects.
First of all, a reasonable light source layout is the basis for reducing glare. The arrangement, spacing and luminous angle of the LED light source in the panel light will directly affect the generation of glare. By optimizing the light source layout, it is possible to ensure that the light is evenly distributed inside the panel light, reduce the appearance of local strong light points, and thus reduce the risk of glare.
Secondly, the use of optical elements such as shading plates or shading strips is also an effective means to reduce glare. These elements can block part of the direct light, causing the light to scatter or refract during propagation, thereby preventing the light from directly irradiating the human eye. At the same time, the design of the shading plate or shading strip also needs to match the light source layout to ensure the uniformity and consistency of the lighting effect.
In addition, the optical lens design of the LED panel light is also crucial. The lens can focus or diffuse the light emitted by the LED, thereby adjusting the distribution and angle of the light. By reasonably designing parameters such as the shape, material and surface treatment of the lens, the propagation path of the light can be further optimized and the generation of glare can be reduced.
In addition to the above measures, surface treatment technologies such as anti-glare films or coatings can also be considered to reduce glare. These technologies can form a layer of fine texture or structure on the surface of the panel light, causing the light to diffuse or scatter when it hits the surface, thereby reducing the glare of the light.
In summary, back-lit energy-saving led panel light t-bar keel type can effectively reduce the generation of glare through reasonable light source layout, the use of shading plates or shading strips, optimized optical lens design, and the use of anti-glare films or coatings and other optical design methods. These measures can not only improve the visual comfort of users, but also further improve the lighting quality and energy-saving effect of LED panel lights.
