General fluorescent lamps are ordinary white light, mainly used as outdoor landscape lamps, but they are rich in color. Can the two be replaced by each other? Let's learn about the difference between LED and fluorescent lamps?
Floodlight: it refers to a lamp whose illuminance on the designated illuminated surface is higher than that of the surrounding environment. Also known as spotlight. In general, it can aim at any direction and has a structure that is not affected by climate conditions. It is mainly used in large-area operation field, building outline, stadium, overpass, monument, park, flower bed, etc. Therefore, almost all outdoor large area lighting lamps can be regarded as projection lamps. The angle of the outgoing beam of the floodlight is wide or narrow, and the variation range is between 0 ° and 180 °. The searchlight is the one with narrow beam.
Fluorescent lamp: generally refers to fluorescent lamp. Traditional fluorescent lamp, namely low-pressure mercury lamp, uses low-pressure mercury vapor to release ultraviolet light after power on, so that the fluorescent powder emits visible light. Therefore, it belongs to low-pressure arc discharge light source. The electrodeless fluorescent lamp is the electrodeless lamp. It cancels the filament and electrode of the traditional fluorescent lamp, and uses the principle of electromagnetic coupling to excite the mercury atom from the original state to the excited state. Its luminous principle is similar to the traditional fluorescent lamp, with the advantages of long life, high light efficiency and good color rendering.
Generally speaking, the decorative components of LED floodlights are relatively heavy, the appearance and light color are also relatively variable, and the range of sunlight is limited, which is more suitable for indoor lighting.
