Material Analysis Of Led Downlights

Material analysis of LED downlights

LED downlights are only available in modern times and can be used as a substitute for ordinary downlights. The light is brighter than ordinary ones.

There are also many kinds of white surface mounted downlight cover materials, such as iron surface, pure aluminum, die-casting aluminum and other materials. Generally speaking, iron-surfaced downlights are cheap, while pure aluminum and die-casting aluminum materials are more expensive, but more durable. Iron-surfaced downlights are mostly used in engineering, but it is recommended that downlights for home improvement use aluminum covers that are not easy to rust.

The lamp cap of white surface mounted downlight is a more important part, and the main material of the lamp cap is ceramic. The reed inside is the most important. There are two kinds of copper and aluminum. The high-quality reed is made of aluminum, and a spring is installed under the contact point, which can strengthen the contact. The other is the power cord of the lamp holder. Good brands use three-wire wiring lamp holders, and some will bring wiring terminals.

Reflective cups are generally of two types: sand cups and light cups. The material is aluminum, which will not change color, and the reflectivity is better.
