whether or mains street lamp, solar street lamps are now using led lamp holder, so how to determine the led light source' LED light source is the light emitting diode ( 领导) For light source of light. 】 Good or bad? Hebei action: led light source look these.
a, see the brightness of lamps and lanterns
general power greater than the power of small bright many, nature price is relatively expensive.
2, see the antistatic ability of lamps and lanterns
antistatic ability of long life usually antistatic is greater than 700 v can be used in the LED lighting.
3, understand the lamps and lanterns of colloid
common colloid for epoxy resin, with uv radiation and fire retardant LED quality is higher.
4, understand the power of lamps and lanterns
according to the different requirements of manufacturers can be divided into constant current power supply, constant voltage power supply ( Constant voltage power supply, also called stabilized voltage supply for the output voltage is fixed, not with load, the external working conditions, such as the input voltage changes. 】 Two, no matter which kind of, the power of the whole service life of the lamp only plays a central role. If the lamps and lanterns is bad, are generally the power supply is burnt out.
6 m street light prices five, understand the lamps and lanterns of radiator
the radiator can see the appearance of lamps and lanterns, if the inner or outer of lamps and lanterns is made of aluminum, could solve the thermal effect of lamps and lanterns to prolong the service life of, etc.
6 and understand the leakage current of the lamps and lanterns
LED is a one-way conductive lights, if there is a resonance current, would become the leakage, leakage of short service life.
to see the light of lamps and lanterns, Angle USES different light Angle is different, want to choose to suit oneself according to actual situation
