Airport lighting: direct lighting VS indirect lighting, LED downlights PK floodlights! ||

Airport lighting has developed to this day, from the main lighting method to the main lighting fixtures, there have been huge changes. Nowadays, it is already an 'industry consensus' to use LED downlights as the main lighting fixtures; but in the past, most of the airport terminal buildings relied on indirect lighting, using LED floodlights and other lamps for basic lighting. Starting from the effect of airport lighting, this article will look at direct lighting built with LED downlights or indirect lighting built with LED floodlights, which one is better. Direct lighting effects, indirect lighting effects, traditional airport keywords, floodlights u0026 indirect lighting, traditional airports usually use indirect lighting methods, with the help of floodlights (and the light source is not LED, common such as metal halide lamps, etc.) as the terminal interior Basic lighting. The principle is to illuminate the space after reflecting the light source through the ceiling, wall and other structures, instead of directly projecting the light source onto the ground. The 'short board' of indirect lighting is obviously high light loss, and only the light of %-% luminous flux shines downward. Take the application of indirect lighting on the ceiling of an airport terminal building as an example. Although the design is novel, the illuminance is low and there are large shadows on the ground. As shown in the figure above, although this indirect lighting method has soft light and good comfort, it uses light. The efficiency is too low. The light area reflected from the ceiling area by the projection lamp on the ground has a strong contrast between light and darkness, and the illuminance is obviously insufficient. Indirect lighting, through the ceiling to reflect the light into the space. Modern airport keyword LED downlights u0026 direct lighting In view of the shortcomings of traditional airport indirect lighting, the new era of airport lighting is more inclined to use direct lighting, such as LED downlights. Illumination type luminaire is the main illumination luminaire, which also greatly improves the utilization rate of light. The light with %-% luminous flux is illuminated downwards. Both the space illuminance and the ground illuminance are guaranteed. The average illuminance value reaches Lx. . The direct lighting created by LED downlights is a combination of 'hybrid lightingSupplemented by 'mixed lighting'. Such a setting, on the basis of ensuring the illuminance, also adds a sense of beauty and enriches the form of airport lighting. For example, the mixed lighting of Baiyun Airport T Terminal Building that was launched in January of each year. In general, the combination of the two lighting methods is a way to maximize strengths and avoid weaknesses. Combining the high light utilization advantage of LED downlights with the smart beauty of LED floodlights has enriched the creative sense of airport lighting design.
