LED应用中芯片的技术发展
LED应用中芯片的技术发展
2013 - 12 - 11
LED照明灯具的驱动电源对变压器、电感器参数的要求十分高，为求精准需花费大量的人力和财力才能实现，工业化生产成本很难进一步下降。对LED驱动恒流源芯片设计技术的创新和突破，新的解决方案可以在LED灯具驱动电源实际应用时，输出电流对变压器和电感的电感量和LED的VF等参数不太敏感。创新技术的关键是优化芯片算法语言。芯片控制输出电流峰值，并通过辅助绕组反馈，使得退磁时间和芯片开关周期的比例固定，这样就可以使得输出电流与外围的电感量偏差和输出电压的偏差无关，而LED的VF值的偏差和电感偏差正是批量生产面临的最大的问题。来说，批量生产的变压器电感量和LED的VF都会有5~10%左右的偏差。而LED照明恒流驱动电源，批量精度可达3%以内，可以容许变压器和电感参数有较大的允差，这就降低了规模工业化生产的成本并促进流水线的持续快速生产

最新符合高可靠LED显示屏的设计要求
最新符合高可靠LED显示屏的设计要求
2013 - 12 - 11
LED显示屏技术发展，客户对其认知度的加深，新客户对LED显示屏的稳定性、可靠性要求的越来越高。所以生产厂家为了符合要求，必须设计出更高可靠的LED显示屏。       目前，LED显示屏行业标准《LED显示屏通用规范SJ／T11141》，在这一行业标准和《电子测量仪2S可靠性试验GBll463》对LED显示屏进行可靠性测定试验，实际上很难实现MTBF不低于10000小时这一可靠性要求，更不能满足高可靠性LED显示屏的要求。而要做得具有高可靠性的LED显示屏，配套产品材料要有很大的提高，设计要求必须包括成热、合理、先进。       一、配套产品材料　   1、LED发光管。　   LED发光管是LED电子显示屏的关键器件，应采用目前成熟可靠的LED产品。产品特点：　   定性好，离散性小。　　ESD指标高：HBM大于4000V。　　衰减幅度小：1000小时小于5％　　耐压能力强：Vr＝10V，Ir　　亮度、波长、角度一致性高。　　配光效果佳：完美的配光曲线。　 可抵御温差、潮湿和紫外线，适用于户外环境。 　2、箱体。整体采用钢板或铝材，采用开门结构。箱体顶部采用销钉和底部采用导向套，保证箱体间...

LED光源更节能更环保
LED光源更节能更环保
2013 - 12 - 11
LED照明灯具在近期得到飞跃的发展，LED作为绿色环保的清洁光源得到广泛的认可。LED光源使用寿命长、节能省电、应用简单、使用成本低，因而在家庭照明都将得到海量的应用。早在2008年，全球每年家庭照明灯座出货量约为500亿个。            LED光源的技术日趋成熟，每瓦发光流明迅速增长，促使其逐年递减降价。LED绿色灯具的海量市场和持续稳定数年增长需求将是集成电路行业继VCD、DVD、手机、mp3之后的消费电子市场的超级海啸！LED灯具的高节能、长寿命、利环保的优越性能获得普遍的公认。       1、LED高节能：直流驱动，超低功耗（单管0.03~1W）电光功率转换竭尽100%，相同照明效果比传统光源节能80%以上。       2、LED长寿命：LED光源被称为长寿灯。固体冷光源，环氧树脂封装，灯体内也没有松动的部分，不存在灯丝发光易烧、热沉积、光衰快等块点，使用寿命可达5万到10万小时，比传统光源寿命长10倍以上。       3、LED利环保：LED...
