Recessed light

A light fixture that is inserted into a hollow ceiling opening is known as a recessed light, downlight, or pot light (also can light (for canister light) in American English occasionally). When placed, it gives the impression that light is coming from a hole in the ceiling and is focused downward as a wide floodlight or a narrow spotlight.

Various recessed lighting styles in a building

"Pot light" or "canister light" denotes a cylindrical illumination fixture with a circular hole, similar to a pot or canister.

A recessed lighting fixture is made up of three components: the housing, the trim, and the lamp. The trim is the part of the lamp that is visible. When gazing up into the fixture, the insert is what is visible, and it also includes the thin lining that surrounds the edge of the light.The housing is the actual fixture, which is mounted inside the ceiling and has a bulb holder inside. Recessed lighting fixtures can accommodate many various types of bulbs, with the quantity of heat they produce being a special consideration.

History

Ivan Kirlin of the Kirlin Company in Detroit, Michigan invented the first recessed lamps in the 1940s.

Advantages

The benefits of recessed lighting include energy efficiency and being a hidden light source. The trade-off is that they are potentially unflattering and generally permanent.

building types

UL 1598 recessed housings typically fit into one of four types in North America.

Before the ceiling surface is installed, IC or "insulation contact" rated new building housings are fastened to the ceiling supports. It is also possible to place these fixtures from within the attic space if the space above the ceiling is reachable. Wherever insulation will come into close contact with the housing, IC housings must be installed.

Non-IC rated new building housings are used in the same circumstances as IC rated housings, with the exception that they need to be at least 3 in (7.6 cm) away from insulation and not in contact with it. Usually, these housings have a 150 watt rating.

In ceilings that already exist and where insulation will come into touch with the fixture, IC-rated remodel housings are used.

It is common practice to use non-IC rated remodel housings for old ceilings that, ideally, have no insulation. However, these also call for a minimum distance of 3 inches (7.6 centimeters) and no contact with insulation. For vaulted ceilings that are both insulated and non-insulated, slanted-ceiling housings are offered.

The housing's primary function is to prevent flammable materials from coming into contact with the hot lighting fixture. Downlights with poor construction can cause fires, but all more recent models have a thermal button that automatically resets for safety.

Based on the diameter of the circular opening where the lamp is mounted, the housings come in a variety of sizes. The most popular diameters are 4, 5, and 6 inches, with 4 inch IC New Construction units currently being less easily available. For specific applications, smaller housings (2 and 3 inch) are also available.

Additionally, the housing can be "air tight," which prevents air from escaping into the loft or ceiling and lowers heating and cooling costs.

In addition to requiring all wiring to be sealed off and gasketed from the plenum air area, the City of Chicago has an extra requirement known as "Chicago Plenum" that mandates the housing be airtight. All recessed luminaires placed in air plenums in the City of Chicago and neighboring municipalities that have enacted the Chicago amendments to the NEC must comply with this housing rating. This rating's goal is to stop possible sparks from shooting out of the luminaire and into the air plenum, where they could then be circulated through the HVAC system.

IEC 60598 is divided into two categories.

Luminaires that can be recessed into ceilings and have heat insulating mats covering them.

Luminaires that can be recessed into ceilings but are not appropriate for thermal insulation.

Trim designs

The styles of recessed lighting have changed as more manufacturers produce high-quality trims for various uses. The most common types of recessed lighting trim are the conventional baffle in black or white.They are designed to block out excess light and give the impression of a clean architectural design.

There are cone cuts that result in an aperture with a low brightness. In order to control the omnidirectional light produced by "A" type incandescent light bulbs and compact fluorescents, multipliers are available.

The purpose of the lens trim is to shield the bulb and provide diffused light. Lensed ends are typically found in damp environments.

The luminous trims incorporate an open downlight component along with the lensed trim's diffused character.

Whether the light is an eyeball style that protrudes from the trim or a gimbal ring style that adjusts inside the recess, adjustable trim provides for adjustment of the light. These lamps enable complete flexibility.

The wall-washer trims are the last option and are intended to remove the common "scalloped light effect".

sort of bulbs

Directional and diffuse are the two kinds of bulbs available for recessed lighting. Reflectors are used in directional lamps (R, BR, PAR, MR) to focus and control the light. The omnidirectional light of diffuse lamps (A, S, PS, and G) regulates the spread of light.
