tab2.1 led elecical characteristic (t = 25 ° c) can be seen from the table 2.1, although the deviation of each led are not too large, but when the led in series, the total deviation can not be ignored. par lamps may be more than the actual power of 9w or less than 9w, directly reflected in the maximum brightness of the lamp is rated or not to be brighter than the rating. when the par lamp when the actual power of less than 9w, and drive the output power is still 9w, then the current flowing through the led has been over rated, long-term work on the led's life and color will have a certain effect. in addition, even if there is no bias led factory, as shown in figure .lawn signs

another disadvantage of remote conol dimmer is easily lost, especially in public places such as schools, office buildings and other places. worse, it needs both with the same brand lighting dimmers, so there is no uniform standard. that is because the brand is not compatible with each other, so the existing market is very small, the future is unlikely to spread. ge, toshiba, panasonic has not yet inoduced remote conol dimmer lighting products, that competitors will not use the product specifications. various manufacturers their own ways, just like cell phone chargers, like, nokia, samsung, lg, motorola are mutually exclusive.

 framework of the main advantages are obvious. output capacitor is usually provided by the load power. supply current is very low, only occasionally by the output capacitor charge pump to recharge. in short, the voltage charge pump in a wide input range can not maintain high efficiency, because the input - output current voltage conversion ratio according to the basic regulation, any more than the input voltage multiplied by the gain from the value of the charge pump output voltage lower will result in an additional power converter, and the efficiency will be reduced in proportion. converter according to the input / output ratio allows the ability to change the gain in the entire input voltage range of the best efficiency. ideally, the gain should be a linear-type changes. in reality, given the number of fixed capacitors and switches, may reach only a limited gain configuration. in figure 4, the input voltage is adjusted, and was fed to three comparators positive nodes. lawn signs
