With a classic light bulb, the light is emitted on all sides. Often, however, you want a narrow beam of light that can be targeted to specific areas or objects. LED reflector lamps are ideal for this task, which is why they are often used indoors. Reflector lamps are illuminants that are equipped with an internal mirroring. Mostly these are vapor-deposited metal layers. This so-called reflector limits the emitted light, which bundles the light and directs it in a certain direction. The luminous flux generated is therefore concentrated in a smaller area, which is why the illuminance of these lamps increases significantly. Due to the purposeful control of the luminous flux, they are ideal for the targeted illumination of certain areas. Objects can also be presented aesthetically with light. When selecting a suitable LED reflector lamp, the beam angle must be determined in advance.
