LED drive power is the power adapter that power supply supply is converted to specific voltage and current to drive LED luminous,
Under normal conditions: the input of LED drive power includes high pressure industrial frequency AC (i.e. alternating current), low-voltage direct, high voltage direct current, low pressure height
Frequency exchange (output of such as electronic transformer).And it is that can become with LED forward drop value that the output of LED drive power is then most of
Change and change the constant current source of voltage.High reliability especially as the driving power of LED street lamp, is mounted in high-altitude, there is waterproof aluminum shell
Driving power does not allow perishable, reduction maintenance frequency if high-quality.High efficiency LED is energy-conserving product, and the efficiency of driving power is wanted
It is high.Structure in lamps and lanterns is mounted on for power supply, it is particularly important.Because under the luminous efficiency of LED is with the raising of LED temperature
Drop, so the heat dissipation of LED is extremely important.Power supply it is high-efficient, its dissipation power is small, in lamps and lanterns internal heat generation amount with regard to small, also
Reduce the temperature rise of lamps and lanterns.It is advantageous to the light decay for delaying LED.High Power Factor power factor is requirement of the power grid to load.One
As 70 watts of electrical appliances below, without compulsory index.Although the little single electrical appliance power factor (PF) of power is lower to electricity
The influence of net is little, but everybody lighting at night, similar load are concentrated very much, and more serious pollution can be generated to power grid.For 30 watts
~40 watts of LED drive power, it is stated that in the near future, perhaps can have certain index request to power factor aspect.Driving
There are two types of mode is now current: one is a constant pressure source supplies multiple constant-current sources, each constant-current source individually gives every paths of LEDs to supply
Electricity.This mode, flexibly, LED failure, does not influence the work of other LED, but cost can be more slightly higher all the way for combination.It is another
It is direct constant current-supplying, the operation of LED serial or parallel connection.Its advantages are more at low cost, but flexibility is poor, also to solve some
LED failure does not influence the problem of other LED are run.Both forms whithin a period of time and are deposited.Multiple constant current output power supply
Mode, can be preferable in terms of cost and performance.It may is that later main flow direction.
