CAS KWCOB Lighting-Cut-off Type Airport Lighting High Mast Lighting-CPPL Series——2024 Alighting Magic Lamp Award for Excellent Road Lighting Product

Comprehensive introduction of the award-winning products:

As mercury lamps have withdrawn from the market, traditional LEDs usually use SMD lamp beads arranged in a row to solve the problem of thermal management in high-power lamp applications. At the same time, due to the scattered arrangement of light sources and the large luminous area, it is difficult to achieve light cutoff to meet the requirements of airport flight safety, resulting in a large amount of spill light above 0 degrees horizontally, especially the glare towards the control tower, which inevitably affects the tower's observation of aircraft takeoffs and landings. The lights need to be confined to the apron. The high-power COB interview, small luminous surface and high power allow each light source to be independently designed with a light-cutting structure to prevent glare, effectively solving the problem of spill light and promoting environmentally friendly lighting applications

Main technical parameters:

1. KWCOB® light source;

2. Cut-off Type optical design is suitable for airport apron high mast lightings, lamp power: 240W, 320W, 480W, 600W;

3. Rated voltage: AC220V±10% or AC380V±8%; frequency 50HZ; working environment temperature: -30℃-+50℃;

4. Lamp power factor ≥0.95, anti-electric shock level II;

5. Light source color rendering index: Ra≥70, R9＞0;

6. 3000K, 4000K, 5000K, color tolerance SDCM≤5;

7. Light efficiency ≥130lm/w;

8. Lamp protection level IP66;

9. The entire shell is treated with electrophoresis and oxidation process, and has anti-corrosion and anti-rust capabilities.

Key points of technical and process innovation:

1. KWCOB® light source with low thermal resistance packaging process;

2. Flat-plate uniform temperature phase change heat sink to meet the multi-angle installation requirements of lamps;

3. High-power COB with small size, optical glass lens and mirror aluminum reflector, long-term use without aging and yellowing, avoiding light decay caused by aging of optical materials

4. KWCOB® high voltage and low current design, the driver can be installed separately for easy maintenance, 240W/320W/480W/600W, multiple power options (customization supported)

5. Cut-off Type structure anti-glare optical design, using KWCOB® and high reflectivity mirror aluminum design system light distribution, can achieve multiple angles of Cut-off Type, no light output above 0 degrees, to prevent glare;Key points of technical and process innovation:

Comparison with similar products or technologies within China and abroad:

1. The current market adopts a multi-light source lighting design scheme, SMD array-type distributed light source, hundreds of light sources are densely distributed, and the luminous area is large, making it difficult to achieve ideal light cutoff, and the glare is serious;

2. SMD array-type distributed light sources usually use PC plastic optical lenses. Plastic materials will yellow during long-term use, which will inevitably cause attenuation;

3. KWCOB® low thermal resistance light source packaging advantage, the light source is smaller in size and matches the combination of high borosilicate glass and mirror aluminum reflector plate, ensuring that the reliability of the lamp is not affected by material aging during the service life of the lamp;

4. The small size of the light source provides sufficient optical design freedom, and adopts an optical scheme of light-cutting polarized design, which effectively reduces the uplight and spillover light, and reduces the glare of remote machine lighting;

5. CAS KWCOB Lighting overcomes the shortcomings of lamp materials from KWCOB light source low thermal resistance packaging, high-efficiency phase change heat sink, light-cutting structure anti-glare optical design, and optimizes the high voltage and low current of the light source to improve the power consumption and heat generation of the driving power supply and reduce the driving operating temperature, matching the overall life of the lamp to exceed 5 years, and the goal is to achieve a ten-year life without shortcomings.
