Lighting basics How to choose the type of lighting

Luminaires are instruments that can transmit, distribute, and change the light distribution of light sources. Today, lamps are very common. Lighting and decoration are very good. What are the basic knowledge of lamps? Secondly, how to choose the type of lamps? Jiuzheng Lighting Network will come to explain for everyone, let's take a look.

Basic knowledge of lighting:

Types of lamps: lighting, indoor lighting, commercial lighting, office lighting, home lighting, floodlights, Geshan spotlights, electrical boxes, wall lamps, ceiling lamps, downlights, spotlights, Geshan lamp panels, brackets, emergency Lighting, European lamps, table lamps/floor lamps, ceiling lamps, sheepskin lamps/cloth lamps, mirror lamps, work lamps, kitchen lamps, crystal lamps, lanterns, low-voltage lamps, room lamps, candle lamps, street lamps, fiber optics, LED lights , brackets, underwater lights, wall lights, buried lights, lawn lights, garden lights, tunnel lights, high ceiling lights, yellow sand glass lights.

Lighting fixtures are divided into two categories: indoor lighting and outdoor lighting.

Among them, indoor lighting includes commercial lighting, office lighting and home lighting.

Outdoor lighting includes floodlights, street lights, high ceiling lights, tunnel lights, garden lights, lawn lights, buried lights, fireplaces, underwater lights, etc. Commercial lighting includes Geshan spotlights, spotlights, downlights, ceiling lights, wall lights, and electrical boxes. Office lighting includes Geshan lamp panel, bracket, and emergency lighting.

Home lighting includes European lights, ceiling lamps, crystal lamps, lanterns, table lamps and floor lamps, sheepskin lamps and cloth lamps, mirror lamps, work lamps, kitchen lamps, low-voltage lamps, room lamps, candle lamps, yellow sand glass lamps, etc. .

How to choose the type of fixture?

Choosing a luminaire type is the basis for determining the overall look, feel and atmosphere of the room. The following are instructions for selecting specific types of fixtures:

1. Direct illumination type lamps: Light is emitted through the luminaire, and 90%-100% of the luminous flux reaches the assumed working surface. This illumination mode is direct illumination. This kind of illumination has a strong contrast between light and dark, and can create interesting and vivid light and shadow effects, which can highlight the dominant position of the working surface in the whole environment, but due to the high brightness, glare should be prevented. Such as factories, general offices, etc.

2. Semi-direct illumination type lamps: a lampshade made of translucent material covers the upper part of the light source, 60%-90% of the light is concentrated to the working surface, and 10%-40% of the cover light is diffused through the translucent lamp cover. And when it is diffused upwards, its light is softer. This type of luminaire is often used for general lighting in lower rooms. Since the diffused light can illuminate the flat top, the height of the top of the room is increased, resulting in a higher sense of space.

3. Indirect lighting type luminaire: It is the illumination method of indirect light generated by shielding the light source. 90%-100% of the luminous flux is applied to the working surface through the ceiling or wall reflection, and less than 10% of the light directly illuminates the working surface. Shopping malls, clothing stores, conference rooms, etc., generally use as ambient lighting or improve the brightness of the scene.

4. Semi-indirect lighting type lamps: In contrast to semi-direct lighting, a translucent lampshade is placed in the lower part of the light source, and more than 60% of the light is directed toward the flat top to form an indirect light source, and 10%-40% of the light is diffused downward through the lamp cover. This method can produce a special lighting effect, so that the lower room has a higher feeling. It is also suitable for small spaces in residential areas, such as foyers, aisles, clothing stores, etc. It is usually best to use this type of lighting in a learning environment.

5. Diffuse illumination type lamps: use the refraction function of the lamps to control the glare, and diffuse the light to the surrounding area. There are two general forms of such illumination, one is that light is emitted from the upper opening of the lampshade and reflected by the flat top, both sides are diffused from the translucent cover and the lower part is diffused from the grille. The other is to use a translucent lampshade to completely block the light and diffuse it. This type of lighting has soft lighting and visual comfort for the bedroom.
