Luminous flux in LED luminaires: efficiently illuminates any space

The luminous flux is a relevant concept that you need to know before choosing an LED luminaire for any space. This term represents the total amount of visible light that a luminaire emits in all directions per second. The luminous flux is measured in lumens (lm) and is one of the main performance indicators of a luminaire. Unlike power (measured in watts), which only indicates how much energy a luminaire consumes, lumens tell us how much useful light it generates. In simple terms, the higher the luminous flux, the more brightness a luminaire will offer us. This concept is different from that of light intensity, which is measured in candelas and describes the amount of light in a specific direction.

One of the main reasons why luminous flux is so important in the context of LED lighting is its impact on visual perception and energy efficiency. Unlike incandescent or fluorescent bulbs, when we opt for a high-flux LED luminaire, we are choosing a lighting option that offers greater visibility without increasing energy consumption. For example, a 60W incandescent bulb can produce a luminous flux similar to that of an 10W LED luminaire. This efficiency in the luminous flux is what makes LED luminaires a preferred choice for modern lighting of spaces that require constant and high quality illumination, such as offices, industrial buildings, warehouses or outdoor spaces. In addition, the luminous flux helps to determine how many luminaires are needed in a space and how they should be distributed to achieve uniform and effective lighting that will allow us to meet safety standards and visual comfort.

Calculating the appropriate luminous flux requires considering the type of activity and environment. Current regulations recommend specific average illuminance levels for each type of activity or space. Well-tuned LED lighting can improve productivity in offices, create a welcoming home atmosphere and optimize visibility outdoors. In addition, by avoiding the use of higher consumption bulbs, the service life of the luminaire is increased and maintenance costs are reduced.

Choosing the right LED luminaire in terms of luminous flux brings multiple benefits. Not only ensures a comfortable and well-lit environment, but also contributes to energy efficiency by reducing the environmental impact. When selecting LED luminaires, it is essential to evaluate not only the luminous flux but also the colour temperature, the colour rendering index (CRI) and the aperture angle. These factors directly affect how we perceive light and its effectiveness in space. In addition, the use of sensors and regulators can help to maximize the efficiency of the luminous flux depending on the available natural light, especially in outdoor or industrial environments. This ensures optimum lighting and even greater energy savings.
