本方案是采用O2(凹凸)公司的IC方案,方案实用,经过市场验证。
通过普通开关即可以实现三段调光,即:

打开开关--->100%输出;

关闭2秒内打开--->40%输出;

再关闭2秒内打开-->10%输出;

 

也可以应用于一些需要调光特殊场合,

 

比如路灯,18:30点打开,按100%功率照亮道路;

 路人少的时候,24:00,关掉再打开,即实现40%的功率输出;

凌晨3点,路人更少,关闭再打开,即实现10%的功率输出;

利用时控器即实现自动化调光的省电功能;

NOTE

  1. 1. Allparameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃of ambient temperature.
  2. 2. Ripple& noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
  3. 3. Pleasesee"ACinput voltagedrop vs.output currentcharacteristics"table.
  4. 4. Deratingmay be needed under low input voltage, please check the static characteristic for more details.
  5. 5. Constant current operation regionis within 50% ~100% rated output voltage. This is the suitable operation region for LED related applications, but please reconfirm special electrical requirements for some specific system design.
  6. 6. Thepower supplyis considered as a component that will be operated in combination with final equipment. Since EMC performance will be affected by the complete installation, the final equipment manufacturers must re-qualify EMC Directive on the complete installation again.
  7. 7. Direct connectingto LEDs is suggested, but is not suitable for using additional drivers.

生产工艺:

采用2层FR4材质基板生产,SMT贴片与插件分开进行,虽然成本略高,但是SMT贴装不良基本为零,插件面也仅仅是插件两件,不良率低,而且经过AOI和外观检查不良率超低。

 

■材料:

电解电容采用红宝石,半导体材料100%进口料,特别是MOS管采用低内阻的ST公司的,每次采购回来都用老化测试温度检验方式,确保比国内大品牌的温度低10多度;

 

■散热处理:

基板倒置于外壳,然后灌胶处理,达到固定插件零件和导热、防止烧机的可能性发生的目的;

MOS管和肖特基通过大焊盘和通孔,把热量导到背面,再通过灌胶把热量快速散发到大气中;

三级调光
■生产:

SMT和DIP外发大厂生产,不用担心设备落后和产能的问题;
