What is the difference between main light, virtual light, downlight and roof lighting? Are these four things?

Downlight is generally installed on the ceiling around the bedroom, living room and bathroom. This kind of hidden lamp embedded in the ceiling projects all the light downward, which belongs to direct light distribution. Different reflectors, lenses, shutters and bulbs can be used to achieve different lighting effects. Downlight does not occupy space, which can increase the soft atmosphere of the space. If you want to create a warm feeling, you can try to install more downlights to reduce the pressure on the space.

The main problem of downlight lies in the lamp mouth. The lamp mouth of some inferior brands of downlight is not resistant to high temperature and is easy to deform, which leads to the bulb not being screwed down. Now, all lamps and lanterns must pass 3C certification before they can be sold, and consumers should choose downlights that have passed 3C certification.

LED ceiling lamps are generally used indoors. Because different varieties have different uses. At present, all countries in the world are stepping up research to improve the light efficiency of LED ceiling, and its luminous efficiency will be greatly improved in the near future. Products are widely used in wedding background layout, hotels, guesthouses, bars, friends' parties, shopping malls, homes, windows, clubs, concerts, karaoke bars, fashion shows, dance halls, stages, opening, celebrations, wedding activities and other places, as long as you want, it will bring you nobility, luxury and romance.

The ceiling lamp can be said to be a small object in the downlight, which means it is a kind of downlight. The ceiling lamp generally uses lamp beads, and the downlight generally uses energy-saving lamps. Ceiling lamps are mainly used for decoration, and downlights mainly refer to lighting ceiling lamps that are not often lit, and are generally used in cabinets and the like. At present, there is basically no difference in China. Downlight is ceiling lamp, ceiling lamp is ceiling lamp. There are even fewer people who call embedded lights, and there are no downlights installed openly or concealed.
