What's the difference between Philips projection lamp and high pressure sodium lamp?
Philips floodlights usually come out of three wires. Regardless of polarity, the blue wire and the brown wire are connected to the live wire and the neutral wire. There is also a yellow line with a hint of green in the middle. The term is yellow rolling green. If there is no grounding wire, this wire can be left empty.
Philips projector wiring experience;
1. Ensure that Philips spotlights are in good condition when receiving goods, and try to check whether the external view of Philips spotlights is damaged when receiving goods.
Second, when floodlights arrive at the construction site to prepare for installation, first of all, the installation personnel should be organized to install according to the installation drawings attached to the factory. First, connect several floodlights and try to see if the installation drawing is correct. If possible, you can arrange a person to try one point at a time to avoid taking it upstairs for installation and disassembly.
Third, it is to remind the installation workers of the importance of fixing and wiring, especially the waterproof outdoor wiring is very important, so it is best to review it when fixing and wiring.
Fourthly, when Philips spotlights are fixedly connected, it is best to check the main power supply with a multimeter to see if there is any wrong connection and short circuit.
Fifth, after all the lighting tests are finished, how about trying to light it for a while, and then recheck it the next day and the third day. After doing this, it is all good, and there will generally be no problems in the future.
Difference between projection lamp and high-pressure sodium lamp;
1, power density selection:
The power density of traditional lamps is 10-25w/m2, and the power density of floodlights can be designed at 3- 15w/m2. The power density of LED lamps in general offices can be 3- 10w/m2. For hotels, shopping malls and other occasions requiring high brightness, it can be 10- 15w.
2. Power supply selection:
The power of floodlight is 1/5 of that of traditional high-pressure sodium lamp.
3. Power factor:
The power factor of floodlights is above 0.95, and that of traditional high-pressure sodium lamps is around 0.6.
4, power efficiency:
The efficiency of floodlight is above 0.9, and that of traditional high-pressure sodium lamp is around 0.6.
5. Service life:
The life of projection light source is 30000-50000 hours, while the life of traditional high-pressure sodium lamp is 3000-8000 hours.
6. Cable investment
Using led lighting can reduce the capacity of lighting cables and transformers, and at least reduce the investment of transformers and cables by more than half compared with traditional lighting.
After having a certain understanding of the wiring experience of Philips projectors, people don't have to worry about the specific wiring problems after buying Philips projectors, but remind everyone to pay special attention to safety when wiring, and master the specific methods and operations of using electricity to avoid affecting personal safety. Of course, Philips spotlights will also provide corresponding instructions and wiring steps. If you don't know how to connect the wires, you can also read the instructions and follow the contents.
