Product Details
Description:
Please confirm that the lamp can be lit and then install the lampshade, because the lamp cover is not easy to remove it once installed.
LED energy-saving lamps for its energy saving, environmental protection, long life and other characteristics, is increasingly widely used, the package features are as follows:
1>. Light board with series and parallel structure design, better than the use of pure series structure of the light board, can extend the lamp life.
2>. Power board, light board produced by the military grade A material, the pad can withstand repeated welding and will not fall off.
3>. Selected matching lamp beads using a large chip package, low light (5000 hours 3%), consistency is good.
Parameter:
| NO. | Parameter | Value |
| 1 | Model | YSU-L120 |
| 2 | Shade diameter | 80mm |
| 3 | Height (including lamp) | 130mm |
| 4 | Power | 6W |
| 5 | Voltage | 85-277V AC |
| 6 | Luminous flux | 280-320LM |
| 7 | Shade | transparent color |
Circuit principle:
The circuit consists of three parts: buck, rectification and filtering
1>.C1, R1 composition RC capacitor circuit, the 220V AC power required for the circuit required low-voltage alternating current.
2>.D1 - D4 composed of bridge rectifier circuit, the low - voltage alternating current rectifier pulse power.
3>.C2 filter, filter out the pulsating DC clutter, the formation of smooth DC, parallel R3 can effectively improve the effect of balanced voltage.
4>.R2 for the LED lamp beads current limiting resistor, can reduce the surge current on the impact of LED lamp beads.
