The most intuitive explanation of the beam angle is the size of the spot range produced by a beam of light shining on the object, and the brightness of the central area. The spot range is the lighting range. Two lamp cups with the same power, the larger the beam angle of the lamp cup, the smaller its central light intensity, the larger and softer the emitted spot area; on the contrary, the smaller the beam angle, the greater its central light intensity , The smaller the divergent spot area, the harder it is.
Simply put, the larger the angle, the larger the light range, the smaller the light intensity, and the fewer dark areas. vice versa.
Application of different angle beam angle:
(1) Narrow beam angle
Narrow beam angle: less than 20°
Suitable places: small corners or decorative lighting, murals, green plants, flowers, etc.
Functions and advantages and disadvantages: The narrow beam angle is mainly used to emphasize prominent items. For example, if you want to make the murals at home eye-catching, use a beam angle of about 15° for lighting. The advantage is that the central area is obviously prominent, and the range of the light spot is relatively small, which is more suitable for accent lighting. The disadvantage is that it is not suitable for large-area lighting, and it is easy to produce a sense of space depression.
(2) Medium beam angle
Medium beam angle: 20°-45°
Suitable places: shadow lighting, wall washing, used for partial lighting, often matched with narrow beam angles to set off items
Functions and advantages and disadvantages: The medium beam angle is mainly used for wall washing or lighting, highlighting the level of light, and creating a good home atmosphere. The advantage is that the lighting area is larger and the light is softer. When you wash the wall with spotlights, you will usually see layered warm lights. The disadvantage is that the beam angle is relatively wide, and the irradiation area is somewhat small.
(3) Wide beam angle
Wide beam angle: 50° and above
Suitable places: It can be used in larger spaces in the home, such as living room, kitchen, study, etc.
Functions and advantages and disadvantages: The wide beam angle is mainly used for large-area basic lighting, and the whole is bright and uniform. The advantage is that the spot range is large, the light is very scattered, the traces on the edge of the aperture are basically invisible, and the brightness is sufficient and beautiful. The disadvantage is that it lacks the level of lighting, and there is almost no contrast between light and dark.
