How to distinguish the illuminance and brightness of LED lamps? In front of LED lamps, the illuminance and brightness of LED lamps seem to be the same thing. The answer is that the illuminance and brightness of LED lamps are different. In a variety of hotel lighting, commercial lighting, home lighting places, light is everywhere. The light of these LED track lights, LED line lights and other lamps can make people feel at home, and can also make products better reflect their own sense of value, and can make our home more warm, I have to say, Lighting can not only adjust the atmosphere, but also affect the mood.

First of all, what are the differences between the brightness and illuminance of LED lamps?

The brightness of LED lamps refers to the physical quantity of the intensity of light (reflection) on the surface of the luminous body (reflector). The human eye observes the light source from one direction, and 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 brightness of the light source unit, that is, the luminous intensity on the unit projection area, when we stand at a certain position and observe the illuminated surface, we can see the brightness (brightness) of the surface. Brightness refers to the degree to which the light emitted or reflected by an object is perceived by the human eye, that is, it focuses on the degree of human perception.

The illuminance of LED lamps, in short, is the amount of light emitted by the bulb. The luminous flux is incident on a surface with a certain intensity of light in a certain direction. At this time, the illuminance of this surface can be measured. Illuminance is an objective parameter, which is the amount of light that we use to detect the actual arrival of light on a certain surface. That is, how much light falls on the surface of the object being illuminated.

It is not difficult to find that brightness is not only related to the material and color of the reflective surface, but also to the position and angle of observation by the human eye. In addition, whether the surface is black or white, wood or stone, the illuminance value is the same. This surface will reflect light, probably specular, or more likely diffuse, reflecting light in many directions in space.

Secondly, what effect does the illuminance and brightness of LED lamps have on our lives?

All indoor space lighting needs to assess the horizontal illuminance of the work surface, but pay attention to the adaptability of illuminance and color temperature. For example, in our work, it is not enough to change the light color in the office, but also pay attention to the illuminance. High illuminance and low color temperature will make people feel stuffy, while low illuminance and high color temperature will make people feel gloomy and tired, resulting in reduced work efficiency.

In life, there will be the trouble of looking bright but not bright enough, but what we want is actually the brightness of the space. Strictly speaking, lighting design is the design of spatial brightness distribution, which should be determined according to the function of the space and human activities. This light and dark distribution relationship also includes the LED lamps themselves as space elements.

This article mainly describes how to distinguish the illuminance and brightness of LED lamps. In commercial lighting projects, rational use of the illuminance of LED track lights, LED line lights and other LED lighting fixtures can make the lighting space more comfortable and allow customers to enjoy it. Bring high-efficiency, energy-saving and environmentally friendly lighting to each owner.
