LED has been widely used in many fields as a lighting source, including industrial lighting, venue lighting, tunnel lighting, sports lighting, etc. Billionaire Lighting has been committed to R&D and production of LED lighting products and applications since its establishment in 2013, and is an expert in LED lighting. We found that customers often ask about the concept of LED lighting beam angle. Today, we would like to explain it to you.
What is beam angle?
Beam angle refers to the angle between the center line of the beam and the time when the light intensity decreases to 50% of the maximum light intensity of the center line. Beam angle describes how the light beam of a light source radiates outward from the center line of the light beam. LED light emitting angle is also called power angle. We usually use half power angle, that is, the angle at 50% luminous intensity. Of course, some people use 60%, 80% or even 90% angles, depending on different application areas.
What are the types of beam angle?
LED lights can have many different types of beam angles, such as 15°beam angle, 24°beam angle, 40°beam angle and 60°beam angle. Generally speaking, the range of beam angle of downlights is about 10°~ 60°, and the beam angle of ceiling lights is 140°. Different beam angle of LED lights can emit different lighting effects. In lighting design, it is generally necessary to choose which beam angle lamps to use according to the actual situation.
What are the characteristics of different beam angles?
Generally speaking, the smaller the beam Angle, the colder the light, on the contrary, the larger the beam angle, the softer the light.
1. Narrow beam
Beam Angle <20 degrees (less than 20 degrees is narrow light beam)
Main functions: accent lighting, highlighting effect
Applicable scene: Household decoration pieces, statues, plants, flowers, mainly to highlight the decoration;
Feature summary: Narrow beam Angle is small and close to the center light, strong light is prominent, and the spot range is relatively small, so it is suitable for accent lighting.
2. Medium beam
Beam Angle 20-45 degrees
Main functions: wall washing or local lighting, highlighting levels, light and shade contrast.
Applicable scene: wall washing, decorative painting lighting, local lighting;
Feature summary: At this time, the light spot is larger, the light is soft and the light will show a uniform distribution of arc projection on the wall. When we wash the wall with a downlight, we can create a layered, curved halo.
3. Wide beam
Beam Angle >50 degrees
Main functions: ambient lighting or basic lighting, relatively uniform lighting ;
applicable scene: kitchen, study room, home entertainment space;
Feature summary: At this time, the Angle is large, the light shining on the ground will be more scattered, basically can not see the light spot, very suitable for providing environmental light, and the light level is relatively not so obvious.
In short, the choice of wide beam angle lamps can make the whole space have a wider range of light irradiation and a softer atmosphere. Narrow beam angle is generally suitable for making accent lighting because of its prominent light intensity in the center and relatively small light spot range. For example, if you need to light up a very delicate ornaments at home to make a little gorgeous light, you can choose Narrow beam angle.
On the same object, the choice of different beam angle will also bring people completely different visual feelings and atmosphere. In practical application, it is necessary to comprehensively consider other conditions such as projection distance, environment brightness, etc..We should choose different beam angle according to different requirements.
