1. The phase line is wrong Generally, the outdoor engineering application is a 3-phase four-wire system. Take the national standard as an example. The rated working voltage between each phase line and the neutral line is 220Vac, and the voltage betwe...
As far as street lamps are concerned, the ambient temperature of LED street lamps is not static. The range of use of LED street lamps determines that they are greatly affected by the environment. For example, if the temperature changes, the LED curre...
(1) The output voltage or power of the output of the driver exceeds the working range of the electronic load meter. (especially in CV mode, the maximum test power should not exceed 70% of the maximum load power, otherwise the load may be over-power p...
1. Excellent explosion-proof performance, can be safely used in various flammable and explosive places 2. Using LED chips, optimized LED package structure, achieving low light decay, high light efficiency, energy saving and environmental protection; ...
First, choose according to actual needs; Second, consider the comprehensive cost-effective choice; Third, the appropriate power, illumination and color temperature. www.risingstarlighting.com
The main material of solar panels is silicon. When the solar panel is exposed to light, it can convert light energy into electrical energy, which can cause electrical energy to flow from one side to the other. The problem with this is that the panel ...
The peak power under solar power conditions is the maximum output power of a standard solar power STC (component), unit peak, or using the symbol Wp. STC: European Commission defined by the 101 standard, radiation intensity 1000 w / m 2, air quality,...
(1) Low-voltage energy-saving lamps: low power, high light efficiency, but the service life is 2000 hours, the low voltage tube is black, generally suitable for solar lawn lights, garden lights. (2) Low-pressure sodium lamp: low-pressure sodium has h...
