LIGHTALL- Focus On LED Screen Field For More Than 10 Years.
LIGHTALL's Transparent Led Glass
While producing transparent led glass, Shenzhen Lightall Optoelectronics Co., Ltd. only establishes cooperation with suppliers who are in line with our internal quality standards. Every contract we sign with our suppliers contains codes of conduct and standards. Before a supplier is finally selected, we require them to provide us with product samples. A supplier contract is signed once all our requirements are met.
Over these years, we have made great efforts in constantly improving our products in order to earn customer's satisfaction and recognition. We finally achieve it. Our LIGHTALL now stands for high quality, which is widely recognized in the industry. Our brand has earned lots of trust and support from customers, both old and new. To live up to that trust, we will keep making R&D efforts to provide customers with more cost-effective products.
We conduct customer satisfaction survey through LIGHTALL and community platforms like facebook and twitter to gather frank feedback, promote communication, and effectively upgrade transparent led glass.
Secondly, we need to do the following points in the maintenance of LED flood light:
1. In the routine inspection, if the glass cover is found to be cracked, it should be removed in time and returned to the factory for repair.
2. Long-term “wind, meal and sleep” LED floodlights will encounter strong winds and heavy rain. If you find that the projection angle of the lamps changes, adjust the appropriate illumination angle in time.
3. When using LED flood light, you need to use it in accordance with the specifications and guidelines provided by the lamp flood light manufacturer. It is difficult to guarantee that electronic products will not be 100% damaged. If the lamp is found to be damaged, it should be removed and repaired in time Or replace.
The waterproof insulating mortar of LED flood light has the following characteristics:
(1) It has excellent viscosity, water resistance and moisture resistance.
(2) It is used in LED flood light body, has excellent high and low temperature resistance, even in cold weather conditions, it can still maintain activity and tight waterproof sealing effect.
(3) It has chemical corrosion resistance such as alkali, acid and salt.
(4) Good formability, suitable for special-shaped filling, sealing and waterproofing.
(5) High voltage resistance, suitable for waterproof sealing at 600V high voltage buried cable joints, so it is also very stable and reliable for conventional LED floodlights.
In structure, it is divided into fixed capacitors and variable capacitors. The capacitor has infinite resistance to DC, that is, the capacitor has a DC blocking effect. The resistance of a capacitor to alternating current is affected by the frequency of alternating current, that is, capacitors of the same capacity present different capacitive reactances to alternating currents of different frequencies. Why do these phenomena occur? This is because the capacitor relies on its charge and discharge function to work, when the power switch s is not closed.
When the switch S is closed, the free electrons on the positive plate of the capacitor are attracted by the power source and pushed onto the negative plate. Due to the insulating material between the two plates of the capacitor, the free electrons from the positive plate accumulate on the negative plate. The positive plate is positively charged due to the decrease of electrons, and the negative plate is negatively charged due to the gradual increase of electrons.
There is a potential difference between the two plates of the capacitor. When this potential difference is equal to the power supply voltage, the charging of the capacitor stops. If the power is cut off at this time, the capacitor can still maintain the charging voltage. For a charged capacitor, if we connect the two plates with a wire, due to the potential difference between the two plates, electrons will pass through the wire and return to the positive plate until the potential difference between the two plates is zero.
The capacitor returns to its neutral state without charge, and there is no current in the wire. The high frequency of the alternating current applied to the two plates of the capacitor increases the number of charging and discharging of the capacitor; the charging and discharging current also increases; that is to say, the obstructive effect of the capacitor on the high frequency alternating current is reduced, that is, the capacitive reactance is small, and vice versa Capacitors have large capacitive reactance to low-frequency alternating current. For alternating current of the same frequency. The larger the capacity of the container, the smaller the capacitive reactance, and the smaller the capacity, the greater the capacitive reactance.
