Common dimensions, parameters and classifications of LED downlights
LED downlight is a type of lighting fixture that is embedded in the ceiling and emits light. LED downlight is a directional lighting fixture. Only its opposite side can receive light. The beam angle is condensed, the light is concentrated, and the contrast between light and dark is strong. The illuminated object is more prominent, the lumens are higher, and the quiet environment is more set off.
LED downlight commonly used standard size and parameters:
2.5 inch LED downlight size parameters: opening (Φ80)-table page size Φ102×H30 power 3W
3 inch LED downlight size parameters: opening (Φ90)-table page size Φ112×H30 power 5W
3.5 inch LED downlight size parameters: opening (Φ100)-table page size Φ122×H30 power 7W
4 inch LED downlight size parameters: opening (Φ120)-table page size Φ146×H30 power 9W
5 inch LED downlight size parameters: opening (Φ150)-table page size Φ180×H30 power 12W
6 inch LED downlight size parameters: opening (Φ160)-table page size Φ190×H30 power 15W
Common categories of LED downlights:
1. Classified by installation method: embedded LED downlight and surface mounted LED downlight;
2. Classified by light source: Divided into LED patch light source downlight, LED high-power light source downlight and LEDCOB light source downlight;
3. Classification by place: LED downlights for home lighting, LED downlights for commercial lighting and LED downlights for engineering lighting; classification by light source anti-fog category: ordinary LED downlights and anti-fog LED downlights
Applicability of LED downlights to various places:
In recent years, more and more offices and even homes have used LED downlights. Because the applicability of LED downlights for indoor lighting is more and more known by people, and more and more popular. LED downlights have the applicability of indoor lighting that some other lamps can't match or even other LED lamps can't match.
LED downlights do not occupy indoor space. LED downlights are installed indoors. Because of the privacy of the lamps, they will not produce a feeling of oppression, on the contrary, they will produce a warm effect. Therefore, home improvement can choose to install multiple downlights to reduce space pressure. Generally, LED downlights are used more in hotels, homes, coffee shops, and shopping malls.
Downlights are generally used for indoor lighting in shopping malls, offices, factories, hospitals, etc. They are easy and convenient to install and are loved by people. LED downlights inherit all the advantages of traditional downlights, with low heat generation, long power-saving life, and minimal maintenance costs. Early LED downlights were not acceptable to customers due to the high overall cost of LED lamp beads. With the decrease in the price of LED downlight chips and the improvement of heat dissipation technology, a solid foundation has been laid for LED downlights to enter the commercial field.
