Led explosion-proof lamp is broken, can users repair it themselves? What is the maintenance method of led explosion-proof lamp?
Many manufacturers' after-sales commitments are a three-year warranty and a five-year warranty, but this requires the user to disassemble the led explosion-proof lamp and send it back to the manufacturer. The manufacturer will also repair and re-deliver the LED high ceiling lights to the user free of charge. However, what are the places where led explosion-proof lamps are used? Most of them are listed companies, national units or special factories and mines. They cannot be without lighting.
Even with a spare light, there is additional overhead in dismantling a light by a professional electrician. It takes a lot of time to send the led explosion-proof lamp back, repair it and return it to the customer. This also shows that in fact, such after-sales is not completely free for customers.
The led explosion-proof lamp provided by the led explosion -proof lamp manufacturer has an after-sales warranty. According to the national three guarantees, it is necessary to return to the factory for maintenance-free, and the LED explosion-proof lamp manufacturers have indeed done it. They are not at fault. Therefore, many manufacturers, in order to grab more orders, led explosion-proof lamp accessories use materials of insufficient quality, the price will naturally have an advantage, but the product quality will decline. Even if there is a failure, returning for repair, there is not much cost for the LED high-top lamp manufacturer. For some low-cost accessories, it is enough to find a supplier to replace it. Therefore, many LED explosion-proof lamp manufacturers will choose to do so, which is also the price of many led explosion-proof lamps on the market is very cheap, but can also give you three years, five-year warranty reasons.
Then some people say that the LED explosion-proof lamp is just a lamp bead and a driving power supply. If the maintenance personnel are people who understand the technology of the LED explosion-proof lamp, can it be repaired by itself? Is it possible to understand the structure of the LED high-top lamp and the entire accessory? problem. However, I believe that no one supplier or user will hire such a high-paying technician to use such high capital investment just to prevent the sudden failure of the LED explosion-proof lamp. In the current market, a technical talent who knows the production technology of LED high-top lamps has an annual salary of between 15 and 250,000. This is also very uneconomical.
