Luxmeters are widely used
1. General public place application
In order to ensure that people can live under suitable light, our country has formulated health standards for indoor (including public places) illuminance, and uses illuminometers to measure the illuminance of various places.
2. Lighting production industry, photography industry, stage lighting layout, etc.
The illuminance meter has been successfully applied to many projects, such as lighting production industry, photography industry, stage lighting layout, etc. Different models of illuminance meters can meet different measurement requirements.
3. Factory production line application
In the factory, the illumination requirements on the production line are relatively strict. Continuous work will cause visual fatigue and greatly reduce work efficiency. Usually the illumination requirement is ≥1000Lx. For places with relatively high illumination requirements, a large-range illuminance meter can be selected, with a super-large range. Can deal with strong light illumination measurement.
4. The application of illuminance meters is very extensive, including the applications in our daily life, such as factories, warehouses, schools, offices, homes, street lamp construction, laboratories and so on.
How to correctly understand the relationship between illuminance and brightness?
Whether it is museums, restaurants, hotels, homes, etc., these places are inseparable from lighting. It can make commodities more valuable, make food more appetizing, and make homes more warm. It can be said that lighting can affect not only Not only the atmosphere of the space itself, but also the only magic weapon to drive people's mood.
Light can be touched all the time in our daily life, and when talking about light, we must talk about illuminance and brightness. Wait... Some people may ask, aren't these two the same thing? of course not!
What is the difference between brightness and illuminance
First of all, before understanding the relationship between the two, we need to understand the conceptual difference between "illuminance" and "brightness". The following is a diagram of the relationship between various light parameters. After reading it, you should have some understanding:
Illumination
In short, the quantity of light (luminous flux) emitted by the bulb is incident on a certain surface with a certain intensity (light intensity) in a certain direction, and the illuminance of this surface can be measured at this time.
brightness
It refers to the physical quantity of the luminous (reflective) intensity on the surface of the luminous body (reflector). When the human eye observes the light source from one direction, the ratio of the light intensity in this direction to the area of the light source "seen" by the human eye is defined as the The brightness of the light source unit is the luminous intensity per unit projected area. When we stand at a certain position and observe the illuminated surface, we can see the brightness (brightness) of the surface.
