The difference between downlights and spotlights_The difference between cob downlights and downlights

Downlights are lamps that have a screw base that can be directly fitted with incandescent or energy-saving lamps. The downlight is a type of lighting fixture that is embedded in the ceiling and is light-emitting. With this invisible luminaire embedded in the ceiling, all light is projected downwards and is a direct light distribution. Different reflectors, lenses, blinds, and bulbs can be used to achieve different lighting effects. The downlight does not take up space, which can increase the soft atmosphere of the space. If you want to create a warm feeling, try to install multiple downlights to reduce the pressure on the space. Generally used in hotels, homes, and cafes.

Unlike downlights, downlights are more decorative.

The downlights are generally three (5 inches) (4 inches) small (2.5 inches). There are two kinds of downlights: horizontal insertion and vertical insertion. The price of horizontal insertion is a little more expensive than vertical insertion.

Suitable places for downlights: large offices, conference rooms, department stores and specialty stores, laboratories, airports, and some residential homes.

Using the downlight to make the lamp, the installation is easy, does not occupy the place, generous and durable, usually no problem for more than five years, the style is not easy to change. The price is also cheap.

1. Compact and high luminous flux. It consumes 1/3 of the incandescent lamp and has a life expectancy of six times that of an incandescent lamp. The compact design of the 175 size keeps the presence of the luminaire and creates a bright space.

2. Two kinds of reflectors with mirror and frosted. A glittering specular reflector that blends the frosted reflector of the ceiling with moderate brilliance.

3. The sliding fixed card is adopted, which is convenient for construction. It can be installed on ceilings of different thicknesses from 3mm to 25mm, which can be easily removed during maintenance.

4. There are three types of lamps to choose from. There are three types of 2,700k, 4,000k, and 6,700k, which can be selected according to different purposes.

The abbreviation of COB is CacheonBoard (on-board integrated cache) in lighting, COB we call it integrated LED chip COB downlight, as the name suggests, the downlight uses an integrated POWERLED chip.

(1) Maintaining the integrity and unity of the building, will not damage the original settings of the lamp, the light source is hidden inside the building, not exposed outside, no glare.

(2) Energy saving. The downlight of the same brightness consumes a relatively large amount of electricity, and the power consumption of the cob downlight is one-quarter of that of a general downlight.

(3) It is environmentally friendly. Cob downlights do not contain harmful substances such as mercury and do not cause any harm to the environment.

(4) It is economical. Because power saving can reduce the cost of electricity, you can save electricity by tens of dollars a month.

(5) Longevity. The service life of Cob downlights is several times that of other general downlights.

(1) General downlights contain chemical pollutants such as mercury and lead, such as high-pressure sodium lamps, fluorescent lamps, and electrodeless lamps. The cob downlight source does not contain chemically contaminated substances and is a green light source.

(2) The reliability of the cob downlight is high, the cost of maintenance and repair is low, and the operation time is 20,000 hours, while the operation time of the high-pressure sodium lamp and the fluorescent tube is less than 10,000 hours.

(3) Compared with the traditional high-pressure sodium lamp, the energy saving of the cob downlight is reduced by 40%.

(4) The life of the cob downlight is 100,000 hours, while the life of the high-pressure sodium lamp and the fluorescent tube is only 1 to 30,000 hours.
