This phosphor can be excited by light of 390 nm to 480 nm near the ultraviolet wavelength, and the wavelength of the excitation light is 580 nm. The resulting lighting effect is warm white like incandescent lamps, and the color temperature should be around 2800k.
In this way, by changing the proportion of the phosphor, the wavelength of the excitation light can be adjusted. You can get natural white light with a color temperature of 6000k.
Various white LED products using Blu-ray cores and phosphors have long appeared on the market, but warm white light sources are rare. Lumi-tech believes that warm white home lighting products will gradually become a necessity.
In the near future, the light source can be selected by various parameters such as the color brightness level, and warm white will be an indispensable one. Of course, the status of high-intensity cold white light source will not be passive.
But in the field of lighting, you will be able to choose your favorite light source anytime, anywhere, and any occasion.
This SSE phosphor is the first commercial product of Lumi-tech. Lumi-tech also develops other lighting products. These products, including phosphors, will be on display in the near future.
On-Grid Inverter converts DC power to AC power for feeding back to the grid. The frequency of the output voltage of the grid-connected inverter needs to be the same as the grid frequency (50 or 60Hz), which is generally achieved by the oscillator in the machine, and the output voltage will also be limited not to exceed the grid voltage. Modern high-quality grid-connected inverters can have an output power factor of 1, which means that the output voltage and current phases are the same, and the phase difference between them and the grid voltage is within 1 degree. There is a microprocessor in the inverter that can sense the AC waveform of the grid, and according to this waveform, generate voltage and send it back to the grid. However, the electricity sent back to the grid needs to have a certain proportion of reactive power, so that the power of the nearby grid is within the allowable limit. noon) its voltage may rise too high.
If the power of the grid is cut off, the grid-connected inverter needs to be disconnected from the grid quickly. This is a regulation of the National Electrical Code (NEC) in the United States to ensure that when the grid is out of power, the grid-connected inverter will not provide power to the grid, and at this time the workers who maintain the grid will not be electrocuted.
Properly configured, grid-tie inverters allow a home to use alternative energy sources that it generates itself (such as solar or wind power) without cumbersome wiring and without the need for batteries. If there is insufficient alternative energy, the insufficient part will still be provided by electricity from the grid.
Grid-connected inverters are widely used in household photovoltaic power generation systems, commercial and industrial photovoltaic power plants and other scenarios. By connecting to the grid, they help to achieve efficient use of renewable energy and reduce carbon emissions, promoting sustainable development and popularization of clean energy.
