LED Lamp Beads 1. The brightness (measured in MCD) of LED beads varies, affecting their price. LED luminaires must adhere to the Class I laser safety standard. 2. Anti-static capability is crucial. LEDs with strong anti-static properties tend to last longer and are thus pricier. Typically, LEDs with anti-static capabilities exceeding 700V are suitable for lighting applications. 3. LEDs with the same wavelength emit the same color. Consistent color quality commands a premium price. Manufacturers lacking LED spectrophotometers often struggle to produce pure-color products. 4. Leakage current occurs when LEDs conduct in reverse, reducing lifespan and lowering costs. LEDs with significant leakage current are less reliable and cheaper. 5. Different illumination angles result in varying brightness distribution. Specialized angles, such as full diffusion, command a higher price. 6. Lifespan is a critical factor. Quality hinges on longevity, which depends on light decay. Lower light decay leads to extended lifespans and higher prices. 7. The wafer serves as the core of an LED. Wafer prices vary significantly, with Japanese and American wafers being more expensive compared to Taiwanese and Chinese ones, which are generally cheaper. 8. Wafer Size refers to the square dimensions of the wafer. Larger wafers offer superior LED quality and command higher prices. 9. The encapsulation material is typically epoxy resin. UV-resistant and flame-retardant LEDs are more costly. Outdoor LED lighting should prioritize UV resistance and flame retardancy, ensuring durability against environmental conditions. Each product has unique design considerations tailored to specific uses. Key safety aspects include electrical, fire, environmental, mechanical, health, and usage safety, all aligned with international and national standards. LED Driver Power Supply 1. High reliability is paramount, especially for LED streetlights installed at high altitudes, where maintenance is challenging and costly. 2. Efficiency is key for energy-saving products. High-efficiency drivers minimize power loss, reducing heat generation within the luminaire. This improves LED performance and extends lifespan by mitigating thermal stress. 3. Power Factor indicates how efficiently the power supply interacts with the grid. While below 70W devices face no strict mandates, nighttime overloads can strain the grid. Future regulations might require higher power factors for mid-range drivers (30-40W). 4. Two primary driver methods exist: constant voltage with multiple constant currents or direct constant current supply. The former offers flexibility but is costlier, whereas the latter is cheaper but less adaptable. Multi-channel constant current outputs could become the industry norm due to their balanced cost-performance ratio. 5. Surge protection is vital. LEDs are vulnerable to reverse voltage spikes, particularly in outdoor installations like streetlights. Grid surges caused by load switching or lightning strikes can damage LEDs. Drivers must include surge suppression features to safeguard the LEDs. 6. Additional protective features like LED temperature feedback help prevent overheating during constant current operation. 7. Waterproofing and UV-resistant casings are essential for outdoor lighting systems. 8. The driver’s lifespan should match that of the LED to ensure long-term reliability. 9. Compliance with safety and electromagnetic compatibility standards is non-negotiable.
