Publish Time: 2024-11-28
The ultra-high luminous flux density of fcob light strip is achieved through a series of advanced technologies and designs.1. Flip Chip TechnologyAdvantages: The traditional LED packaging method is to connect the LED chip to the substrate through welding wires, while the flip chip technology directly flips the LED chip on the substrate, eliminating the step of welding wire connection.Effect: This technology reduces light loss and improves light output efficiency. The chip is in direct contact with the substrate, the heat conduction effect is better, the thermal resistance is reduced, and higher current drive is allowed, thereby increasing the luminous flux density.2. High-brightness LED chipChip selection: fcob light strip usually uses high-brightness LED chips, which have higher luminous efficiency and larger luminous area.Material improvement: The material and structure of the LED chip are optimized to improve the internal quantum efficiency, so that the light output per unit area is higher.3. Optimized packaging technologyPackaging material: Use high-transparency packaging material to reduce the absorption and scattering of light in the packaging material.Optical design: Fine optics design during the packaging process ensures that light can be output at the best angle and reduce light loss.4. Heat dissipation designThermal management: fcob light strips are usually equipped with efficient heat dissipation systems, such as heat sinks or thermal paste, to ensure high light output in high-temperature working environments.Thermal resistance reduction: By optimizing the substrate material and structure, the thermal resistance is reduced, so that the LED chip can still maintain good heat dissipation under high current drive, thereby achieving higher luminous flux density.5. Drive circuit optimizationConstant current drive: A constant current drive circuit is used to ensure that the LED chip can work stably at high brightness under different temperature and voltage conditions.Dimming control: Advanced dimming control technology can adjust the brightness as needed without affecting the light output, further improving the utilization rate of the luminous flux density.6. Application of optical lensesLens design: In some fcob light strips, optical lenses with high transmittance are added. These lenses can further concentrate the light and increase the luminous flux density.Beam control: The design of the lens can control the divergence angle of the beam, making the light more concentrated, thereby achieving a higher luminous flux density in a specific area.7. Overall system optimizationIntegrated design: The overall design of the fcob light strip has been optimized, and comprehensive consideration has been given to multiple links from chip selection to packaging, heat dissipation, and driving to ensure that each link can maximize its contribution to the improvement of luminous flux density.Through the comprehensive application of the above-mentioned multiple technologies and designs, the fcob light strip can achieve ultra-high luminous flux density and meet various high-brightness and high-density lighting needs.
