The basic parameters of LED lighting
Let us introduce the basic parameters of LED lighting:
LED spotlights voltage 220V, 110V, 36V, 24V, 12V, several, so we choose the power
Time to pay attention to the corresponding voltage.
2) Operating temperature:
Because the spotlights are usually used in the outdoor more, so this parameter is more important, the temperature
The requirements are relatively high, the general situation we require the outdoor temperature at -40 ℃ +60 ℃ can work
3) Protection class:
This is an important parameter of the spotlight, but also affect the quality of the current guardrail tube an important indicator, we have to carry out stringent requirements, we use in the outdoors, requiring water level should be above IP65 is the best. Pressure, resistance to fragmentation, resistance to high and low temperature, fire, impact aging level
4) Control mode:
LED lighting for most of the more monochrome, can usually be coupled with a constant current drive power can work, but the constant current source of the quality of the impact of LED lighting a great impact, so have to use efficient Constant current drive.
5) Beam angle:
Its luminous angle is generally narrow (20 degrees), in (about 50 degrees), wide (about 120 degrees) three.
Most of the previous LED lighting is made of low-power LED, but now with the development of high-power technology, high-power LED lighting is also more and more common high-power LED lighting can do 20W or so. But the current 1W, 3W, 5W application of a wide range.
7) LED lighting fixture specifications: MR16, GU10, HR16E27, JDRE27, JDRE14, PAR20, PAR30, PAR38, PAR56 and other different specifications.
