The light source of courtyard lamps is an important component of all lighting products. According to different lighting requirements, different brands and types of light sources can be selected. Commonly used light sources include incandescent lamps, energy-saving lamps, fluorescent lamps, sodium lamps, metal halide lamps, ceramic metal halide lamps, and new LED light sources. Characteristics of each light source:
Incandescent emission refers to the visible photoelectric radiation generated by atoms excited by heat. Incandescent lamps use the principle of incandescence to emit visible light by passing an electric current through a tungsten wire in a vacuum, heating the wire to incandescence. The color temperature of an ordinary incandescent lamp is 2800K, which is slightly yellow compared to natural light and appears warm. The advantages and disadvantages of incandescent lamps are low cost, simple and convenient use and installation. Suitable for frequent switching on, with low impact on lamp performance and lifespan when turned off. The advantages and disadvantages of incandescent lamps are short lifespan and low luminous efficiency. The visible light radiation emitted by incandescent lamps is generally less than 10% of electrical energy, and most of the energy is converted into infrared radiation, generating a large amount of heat. In addition, the ultraviolet radiation emitted by incandescent lamps is also relatively high, which can cause fading of the irradiated items.
