Drive power, constant current and constant voltage, it is very convenient to make a fuss about the drive. Many electronic components can be replaced. Even the same electronic components have high and low prices, and the prices are different. If all low-end electronic components are used, As a whole, the cost is very low, the driver is cheaper, and the finished floodlight can be cheaper. There is another thing that depresses me the most. It is such a low price and it is not ashamed to say that the warranty is several years. Take the 10W LED flood light as an example, the market should be at least 20 yuan. Such a price has a warranty. I don’t think anyone will know it. It’s really impossible to imagine how low the cost is at such a price. The bottom line is no more.
Let’s talk about quality assurance. I searched the cheapest materials from the market and made a finished LED floodlight. Even if the price is high, 30 yuan, there are labor, lamp beads, drivers, housing, manufacturer profits, and 30 yuan. Calculating the loss in this way, the cost that can be divided into the lamp beads, the driver, and the housing is not much. The lowest cost of labor is 5 yuan, the minimum profit is 5 yuan, and the loss of 3 yuan is added, and the waterproof material of the power cord is added. When you get up, you can count 3 yuan, so that the lamp bead drive shell is only 14 yuan. It is really talented to keep the cost so low. Some users also want to buy it and try it. See how long it can last, like this. The low cost should not mention the light decay and the life span.
As a replacement product of electric light sources, floodlights have been recognized by more and more people and have been applied in many fields. Mainly used for billboards, highways, railway tunnels, bridges and culverts, squares, buildings and other places. So what is a floodlight? Floodlight is a point light source that can illuminate evenly in all directions, and its illumination range can be adjusted arbitrarily , Which is represented as a regular octahedron in the scene. Floodlights are the most widely used light source in the production of renderings. Standard floodlights are used to illuminate the entire scene. Multiple floodlights can be used in the scene to produce better results.
