Airport apron lighting, stadium lighting, square parking lot high mast lights, medium pole lights

Pain points of high-power floodlight lighting

1. Traditional mercury lamps (sodium lamps, metal halide lamps) have high energy consumption and mercury pollution has been banned. Array LED lamps use dispersed arrangement of lamp beads to solve the problem of thermal management, but the aging of the lamp bead bracket and the light decay caused by the sulfidation of the silver plating layer need to be upgraded and optimized;

2. The optical light cutoff difficulty of array LED lamps is increased due to the large area of dispersed arrangement of light sources, resulting in large-angle light overflow. The high-power lighting solution of LED array is more likely to cause strong glare than traditional mercury lamps (sodium lamps, metal halide lamps);

3. High maintenance cost: high-power lamps generally have fast light decay and short life, with a service life of less than 3 years. Mercury lamps with a power of more than 1000 watts are generally replaced once a year, and the maintenance cost is very high. 1000W traditional array LED lamps are difficult to avoid aging and light decay of light source brackets and plastic optical materials;

CAS KWCOB LIGHTING uses kilowatt-level COB light source packaging technology to create a high-quality solution for high-power COB floodlights, with outstanding advantages:

1. Leading light source technology: using new ceramics phosphor materials, combined with kilowatt-level light source packaging technology and low thermal resistance packaging technology, to solve the problem of light decay caused by high temperature generated by traditional powder phosphor in the heat island of silicone; reduce the working temperature of the light source, ensure the stability and efficiency of the light source, and extend the service life.

2. Excellent light distribution and cutoff: 1) Flexible light distribution: optical glass is matched with aluminum reflector to provide a variety of light distribution solutions to meet the lighting needs of different spaces. 2) Cutoff optical structure: high-power COB small luminous surface meets the cutoff design to the greatest extent, reduces uplighting and spill light, avoids light pollution, and gives the lighting a reasonable border, improving the lighting quality.

3. High-quality optical materials: high borosilicate glass lens and mirror aluminum material are selected, with stable optical performance and good weather resistance, eliminating the light decay problem from plastic material , can adapt to harsh environments, and ensure long-term lighting effects.

4. Efficient heat dissipation design: 1) Structural optimization: High thermal conductivity aluminum phase change structure combined with central heat extraction and vertical fin design optimizes temperature uniformity and improves heat dissipation efficiency. 2) Phase change heat dissipation: Rapid heat extraction, balanced light source and heat sink, lower temperature, reduce light decay, and improve stability.

5. Anti-glare design innovation: Adopt high-power, small-light-emitting surface, high-density COB light source, with deep anti-glare optical design, control glare and provide comfortable lighting.

6. High-voltage packaging technology: High-voltage COB light source reduces the power consumption of the driving power supply, extends the life, supports separate installation and centralized management, and reduces maintenance costs.

7. High overall cost performance: Advanced technology ensures high product reliability, reduces failures, reduces maintenance costs, and significantly improves the cost performance of long-term use.
