Light device (lighting device) - a device containing one or more lamps and lighting fixtures, redistributing and converting light emitted by lamps, and intended for lighting or signaling.
The luminaire is a light device that redistributes the light of a lamp inside large corners.
A searchlight is a light device that redistributes the light of a lamp inside small corners.
The projector is a light device that redistributes the light of a lamp with the concentration of light flux on a surface with small dimensions or in a small volume.
Lighting fixtures (lighting fixtures) are part of a light fixture designed for redistribution and conversion of lamp light, for its attachment and connection to the power system, for the ignition device and stabilization of operation, for protecting the lamp from mechanical damage and isolating it from the environment.
The optical system of a light device is part of a lighting fixture consisting of optical elements that participate in the redistribution and transformation of lamp light.
Types of light devices

An attached light device is a light device rigidly attached directly to the surface of furniture or equipment.
Wall light device (wall lamp) is a light device for mounting on a vertical surface.
The reference light device is a light device for installation on the upper side of a horizontal surface or fixing to it by means of a post or a support.
A desk light device is a supporting light device for installation on a table or other furniture.
Floor light (floor lamp) - a supporting light device for installation on the floor.
The crowning light device is a supporting light device for installation on a vertical support.
The console light device is a reference light device whose light center is displaced relative to the vertical passing through the point of attachment of the support.
The end light device is a cantilever light device mounted on a support without an intermediate bracket.
A hand-held light device is a portable light device that, during operation, is placed in the hand or attached to human clothes.
Stationary light device - a light device fixed on the site of operation, for removal from which the use of the instrument is required.
A non-stationary light device is a light device that can be removed from the field of operation without the use of a tool and transferred or moved to another location.
A portable light device is a non-stationary light device with an autonomous power source or connected to an electrical network by a flexible wire that is not disconnected when the light device is moved by hand.
A moving light device is a light device whose design allows you to change the position in the space of its optical system during operation.
Adjustable light device - a light device whose lighting characteristics can be adjusted within certain limits.
Network light device - light
Lighting
General lighting - general lighting of rooms and open spaces.
Local lighting - local lighting of work surfaces.
Utilitarian outdoor lighting - outdoor lighting designed for
ensuring the safe and comfortable movement of vehicles and pedestrians.
Functional and decorative lighting - outdoor lighting designed
to create a safe, comfortable and aesthetic environment mainly for pedestrian areas (sidewalks, parks, squares, landscapes, etc.).
Fixtures
The luminaire of general lighting is a lamp for general lighting of rooms and open spaces.
The luminaire of local illumination is a lamp for local illumination of working surfaces.
Nightlight - a lamp designed to create the lighting necessary for orientation in a room in the dark.
The lighting fixture is a luminaire designed to illuminate individual objects.
Chandelier - multi-lamp hanging lamp for general lighting for residential or public premises.
The luminaire is a luminaire, the design of which allows it to be installed in a line and to route electrical wires through it.
The luminaire of normal execution is a lamp, in which the lamp and the current-carrying part are not protected from dust and water.
Fixture for indoor lighting (a lamp for living spaces, a lamp for public buildings, a lamp for industrial premises) is a luminaire for general and local illumination of flats of apartment houses, public and industrial premises.
Decorative lamp - a lamp, which is mainly an architectural element of the interior and plays a limited role in creating the necessary lighting conditions.

Lighting complexes
Light complex - a device consisting of a set of light devices, individual light-distributing or light-converting elements, structural, electrical and other parts, assembly units or blocks, collected from the consumer, performing its functions only in assembled form and intended for lighting or signaling.
The luminous band is a light complex whose ratio of the length of the luminous surface to its width is more than 5.
The luminous ceiling is a light complex, the dimensions of the luminous surface of which are comparable with the dimensions in terms of the illuminated room.
Slit light guide is a hollow, extended cylindrical or other form of a light-redistributing element of a light complex, most of its internal surface is covered with a mirror-like layer along its entire length, while the light flux of the lamp is inserted into the end of the light guide, and leaves it along its entire length through that part of the surface that not covered by a reflective layer, - a light-transmitting optical gap.
