What is the opening angle of the lamp?<\/span><\/span><\/h1>\n

What is the opening angle of the lamp?<\/figcaption><\/figure>\n

The opening angle of the lamp beam we can define in a simplified way as: the amplitude of the light where most of the lamp’s illumination will be concentrated, about 80%-90%.<\/span><\/span><\/p>\n

This value tells us the angle at which the light beam opens, and thus determines the area it can illuminate depending on the distance to the light source. <\/span>We must bear in mind that LEDs are more confocal than for example halogens and therefore we must pay special attention to this aspect.<\/span><\/span><\/p>\n

Depending on the use we are going to give it, we will be interested in a light source with one opening angle or another. <\/span>The usual thing is to use lights with a smaller opening angle as accent lighting, to highlight decorative items or, if it is a shop, the various products. <\/span>Conversely, lamps with a wider angle, typically from 90 degrees, are used for general space illumination.<\/span><\/span><\/p>\n

The amount of light that a lamp will give us in a given application will not only depend on whether it has more lumens, there are also other factors that influence it, such as the opening angle of the lamp beam.<\/span><\/span><\/p>\n

.<\/p>\n

.<\/span><\/span><\/p>\n

The amount of illumination in the plane is directly proportional to the luminous flux or the number of lumens and inversely proportional to the solid angle of the lamp, that is, the greater the number of lumens of the lamp, the greater the sense of illumination. <\/span>In a certain space, but the greater the angle of opening, the less sense we will get from lighting in this space.<\/span><\/span><\/p>\n

In the following example we try to explain it visually:<\/span><\/span><\/p>\n

.<\/span><\/span><\/p>\n

 <\/p>\n

.<\/span><\/span><\/p>\n

We can see how an 8-watt lamp with only 800 lumens, using it in this application, gives us a greater sense of luminosity (lux), because it shines in the direction we want thanks to its 180-degree opening.<\/span><\/span><\/p>\n

The other lamp that has more lumens but on the contrary has a 360 \u00b0 aperture that wastes the light that illuminates the ceiling, and therefore in the area of \u200b\u200binterest to us it gives a much lower sense of luminosity.<\/span><\/span><\/p>\n

To choose one angle or the other, we must take into account the height that the lamp will have and the surface that will be illuminated. <\/span>If it is high and we have a very wide angle, we will lose the intensity of the light compared to a more focused light, but the illumination will be more uniform. <\/span>On the contrary, to light a room of little height in general, if we use a luminaire that closes the light a lot, shadow areas can be created in which the illuminated areas will be perfectly defined, as if we were using a flashlight.<\/span><\/span><\/p>\n
