| Source characteristics: |
1. Low power consumption : electricity consumption is the same under incandescent lamp brightness of 10% sodium in the quarter.
2.Chip life span of a long working life : 50,000 hours.
3. High-efficiency light color purity, no radiation, no strobe.
4.Response time : faster response time for dozens of nanoseconds (ns).
5.The small size, light weight, impact resistance, waterproofing, anti-corrosion and preventing earthquakes, explosions.
6.Easy adjustment, palette, controllable (and optional white, blue, purple, yellow, green, red).
7. 70V-265V safety : The input voltage, low-voltage DC operation.
8. Green : mercury, lead environmental contaminants MF. |

Compared with the actual annual savings (yuan) |
1,000 sets of lights can be saved :sodium 2452800 degrees - semiconductor (LED) 876000=1576800 degrees 1576800 × 0.76 (yuan per degree) =1198366(1.2million) |
Supporting investment |
LED tunnel light single cost is higher, but supporting generating set , UPS system , transformer , cable , cable crane span structure comes down compared with tradition tunnel light, because of power investing small.The overall invests in compared with tradition tunnel light but saves 15%- 30% as a result of measuring and calculating , adopt LED tunnel light. |
Problems |
Higher product costs. |
1.low efficiency
2.electricity
3.frequent maintenance
4.frangible bulb |
