With the continuous development and progress of social life, people's demand for lamps is getting higher and higher. Among them, downlights can increase the soft atmosphere of the space. How to choose downlights, and what are the purchasing skills of downlights? Let's talk about the knowledge of downlights.
1. First of all, we should pay attention to the selection of lighting materials. However, due to the different use occasions, the materials of the lamps and lanterns selected are also different. If it is used at home, it should be based on durable lamps. Coupled with long-term living, you may wish to use die-cast aluminum. Of course, if it is used in restaurants, hotels and other places, it is recommended to buy iron products, which can be directly replaced when used or broken, which is more economical.
2. Secondly, we should consider the safety of downlights. Regular manufacturers have binding posts at the wiring, and this wiring method is relatively safe. For this reason, in the process of purchasing lamps, we try to focus on such downlights as much as possible.
3. As we all know, the installation direction of downlights is mainly divided into two types, the first is horizontal insertion type, and the second is vertical insertion type, of course, this depends on the size of your own space. If the space is large, you should choose vertical insertion. Of course, if the space is small, you should choose horizontal insertion.
4. For the size selection of the downlight, it needs to be determined according to the size of the aisle. Generally speaking, the size of downlights for home use should be 3 inches, while hotels or some work use usually choose between 4 and 8 inches.
5. I believe that most people only pay attention to the material when choosing downlights. In fact, the material of the bracket is also particularly important. Generally speaking, a slightly thicker one should be chosen to avoid warping.
The raw materials of LED downlight panel: generally have the following: iron sheet, die-casting aluminum, aluminum, stainless steel. Iron sheet home decoration should be used as little as possible, and more for tooling. It is recommended to use die-cast aluminum, aluminum or stainless steel for home decoration.
LED downlight lamp holder safety: The downlight lamp holder is a more important part, and the primary raw material of the lamp holder is ceramics. The reed inside is more important. There are two kinds of copper and aluminum. It is better to use aluminum. The power cord of the lamp holder should choose a three-wire connection lamp.
The reflectivity of LED downlight lamps: the reflector is generally of two types: sand cup and light cup. The material is aluminum, the aluminum will not change color, and the reflectivity is better. Some small manufacturers will use plastic spray to do it. This new process looks good, but it will become dark or even black after a while. The identification method is to look at the regularity of the incision. The incision of aluminum is very regular, and the plastic spray is the opposite.
The direction of LED downlight lamps: If the top space is large enough, buy the vertical plug directly. If the top space is small and cannot be separated, you can consider the horizontal plug type, the price distance is not large, and the horizontal plug price is a little more expensive than the vertical plug.
LED downlight size: Home decoration is generally 2 inches, 2.5 inches, 3 inches, and the aisle can install slightly larger downlights. Tooling generally uses 4 inches - 8 inches of these standards.
LED downlight panel bracket: Another is that the thickness of the panel is very important, which determines the price of a downlight. The importance of the bracket is slightly worse. Generally, it is a black paint bracket. This mainly depends on the thickness. Pinch it with a little force, and it will not cause serious deformation.
