How to choose LED spotlights?3
3、 Downlight or spotlight? Look at the angle of illumination! The difference between tube spotlights varies from house to house, and I believe the most direct way to distinguish tube spotlights is to look at the size of the beam angle. Downlights are usually surface light sources with a light emitting angle of 120 °, while spotlights have a smaller beam angle, commonly used between 15 ° -40 °. Due to the smaller beam angle of spotlights, they can transmit light further under the same luminous flux, making it easier to form a strong contrast between light and shadow to create an atmosphere. Therefore, spotlights are also commonly used for key lighting purposes; And a surface light source like a tube lamp has a large angle of light emission, and when the light flux is sufficient, it will make the space bright, receive light evenly, and have a small light ratio. In other words, the texture of the entire space's light is relatively flat, without hierarchy, and there is no so-called advanced sense. So in the trend of mainstream lighting, surface light sources such as down lights and ceiling lights have gradually reached the bottom of the disdain chain, while spotlights are becoming increasingly popular.
