Lighting fixtures for indoor living and working environments are collectively referred to as. These lamps have both decorative and lighting functions, using various shapes and powers of incandescent lamps (including halogen lamps) or fluorescent lamps. Indoor lights can be installed in six categories: embedded lights, ceiling lights, pendant lights, wall lights, detachable lights, and track lights.
Embedded in the ceiling, only the downward light emitted by general lighting fixtures. It is equipped with a diffuse cover, prism cover or grille on the surface of the light outlet to reduce glare and expand the light of various optical components. OA lighting used in office automation lighting is a type of embedded lighting fixture that strictly controls the brightness of the surface in the direction close to the horizontal angle. It makes the fluorescent light image on the computer very bright, thereby reducing interference with the displayed content on the screen. The vast majority of embedded lighting fixtures have symmetrical light distribution, with only a small number of lighting fixtures installed on adjacent ceilings, emitting asymmetric light distribution.
Indoor ceiling lights are installed on the surface of the ceiling, exposing all shapes of a type of lighting fixture. According to the luminescence situation, it can be divided into three types: full diffusion, downward diffusion, and downward projection.
(1) Fully diffuse type. It uses a diffuse or surface pressed prism shaped transparent material lampshade to illuminate the surrounding spatial light. The light source inside the lampshade is invisible during operation, and the upward light illuminates the walls and ceiling. Therefore, using light colored ceilings in a room can reflect as much ceiling light as possible.
(2) Downward diffusion type. A universal lighting fixture, in which the side of the lampshade is made of opaque or partially opaque material, and light is transmitted from the semi transparent lampshade below. Only a small amount of light illuminates the ceiling.
(3) Downward projection. A light fixture with a small beam angle, used to enhance or supplement lighting. Installed on the ceiling to provide sufficient light for visual work.

Indoor lighting is a type of decorative light fixture that hangs from the ceiling in a prominent position in a room. According to the luminous situation, it can be divided into four types: full diffuse, direct indirect, downward illumination, and light source exposure.
(1) Fully diffuse type. It emits light into the surrounding area and has a dual function of illumination and decoration. In order to achieve good decorative effects, commonly used color semi transparent lampshades and dimmers are used to control the brightness of the light source.
(2) Direct type - indirect type. There is a lot of light up and down, and very little light in the horizontal direction. Usually installed at a height close to the line of sight for lighting purposes such as dining tables and fast food restaurants. These hanging height adjustable lights have a downward pull for enhanced lighting and an upward push for general lighting.
(3) Tube lamp type. The emitted light will produce strong shadows. Used for enhancing lighting in halls, corridors, or stairs. The room in use should usually be equipped with general lighting.
(4) Light source exposure type. It uses high brightness luminescent materials to achieve flicker and excitement, focusing on decoration. Generally, exposed low-power light sources are used and installed in the space above the line of sight. When hanging low, low brightness light sources or dimmers should be used to reduce the brightness of the light source, and a light colored wall should be used behind the lamp.

Indoor lighting fixtures installed on walls, building columns, and other facades. The installation height is closer to the horizontal line of sight. Therefore, it is necessary to strictly control the brightness of the emitting surface. According to the luminous situation, there are four types of light sources: exposure type, diffuse type, strip type, and directional type.
(1) Exposed light source type. Commonly used for decoration. Some are also equipped with transparent and beautiful lampshades.
(2) Diffuse reflection type. Using a small semi transparent lampshade, the surface brightness is low. Usually installed in pairs in corridors, door contours, and mirrors on both sides.
(3) Banded. Using fluorescent lamps or multiple parallel incandescent lamps as the light source, the shape is long and narrow. It can be used for both local lighting workbenches and general lighting. Mirrors, hallways, and foyers installed above. (4) Directional lighting type.
There is a strong upward or downward light. Upward illumination is often used for general illumination, while downward illumination is used for enhanced illumination.

Indoor lights can be moved and placed in place. There are two types of lighting fixtures: floor lamps and desk lamps. They have a solid base, a pillar, and a lampshade surrounding the light source to provide illumination.
(1) Floor lamp. Tall in shape, placed on the floor or coffee table lamp. Light from shadows and light from above provide general illumination, while light from below illuminates the working surface that requires light, providing local illumination.
(2) Table lamp. A smaller shape placed on a desk lamp. The role of local lighting. There is a type of desk lamp used for reading and writing, and its lampshade brightness, lampshade angle, illumination area, and illuminance are all beneficial for reducing visual fatigue and protecting vision.
Track light, indoor light, indoor light, movable light installed on the track

Equipped with embedded wires. The track is installed on the ceiling or wall. Insert a lamp with light projection function into the track, which can move and adjust the lighting direction according to the position of the illuminated object and lighting requirements. It can generate good lighting effects and be used for lighting in exhibitions, showcase windows, and other places.
In addition to the commonly used lamps mentioned above, there will also be combinations of buildings, furniture, and lighting equipment. Through clever processing, the effect of only seeing light but not shining can be achieved. Some become shining building stones, while others become shining furniture. With the increasing demand for interior decoration style, decorative lighting fixtures have emerged, such as holiday lighting fixtures. TS、 Palace lamps, crystal lamps, rainbow lamps, etc. In addition, low-power (35W or 70W) metal halide lamps are also used as indoor lighting sources.
