Introduction to the derived source and component parts of courtyard lights

  Introduction to the derived sources and components of courtyard lights. Since the development of courtyard lights, according to the use environment and design style, different types have been derived, which are divided into three categories: European courtyard lights, modern courtyard lights, and classical courtyard lights. u003cbru003e u003cbru003e  European-style courtyard lamp: Its design style mostly adopts some European-style artistic elements of European countries, with abstract expressions. Such as: Crown courtyard lights. Modern courtyard lamp: Its design style mostly adopts modern artistic elements, and adopts simple techniques to express, such as: spring bud courtyard lamp. Classical courtyard lamp: Its design mostly adopts Chinese classical elements, which are used and modified, such as palace lanterns. These three types of courtyard lights represent different styles and are derived by most manufacturers to cater to the design style of urban buildings. u003cbru003e  The courtyard lamp is mainly composed of 5 major components, namely: u003cbru003e  One, light source u003cbru003e  Light source is an important part of all lighting products. According to different illumination requirements, you can choose different brands and different types of light sources. Commonly used light sources are: incandescent lamps, energy-saving lamps, fluorescent lamps, sodium lamps, metal halide lamps, ceramic gold Halogen lamps and new LED light sources. Characteristics of each light source: u003cbru003e  1. Incandescent lamp u003cbru003e  Incandescent luminescence refers to the visible photoelectric radiation generated by atoms excited by heat. The incandescent lamp uses the principle of incandescent light to let current pass through the tungsten filament in a vacuum, and the tungsten filament is heated to incandescence and emits visible light. The color temperature of ordinary incandescent lamps is 2800K, which is more yellowish than natural light, which is warm. The advantages and disadvantages of incandescent lamps: low cost, easy to use and install. It is suitable for frequent turning on, and the impact on the performance and life of the lamp is very low. u003cbru003e  The advantages and disadvantages of incandescent lamps: u003cbru003e  Short life and low luminous efficacy. The visible light radiation emitted by the incandescent lamp is generally less than 10% of the electric energy, and most of the energy is converted into infrared radiation, which generates a lot of heat. In addition, the ultraviolet radiation emitted by the incandescent lamp is also relatively high, which will cause the fading of the illuminated object. u003cbru003e  2. Fluorescent lamps, energy-saving lamps u003cbru003e  Fluorescent lamps and energy-saving lamps are a low-pressure mercury vapor arc discharge lamp, usually in a long tube shape with an electrode at each end. The lamp contains low-pressure mercury vapor and a small amount of inert gas, and the inner surface of the lamp tube is coated with a phosphor layer. Fluorescent lamps are divided into straight tube fluorescent lamps and compact fluorescent lamps. Straight tube fluorescent lamps can be divided into preheating start, quick start and instant start according to the starting mode, and can be divided into T12, T8 and T5 according to the tube. The compact fluorescent lamp was developed to replace the incandescent lamp that consumes a lot of power, and has the characteristics of low energy consumption and long life. The life of ordinary incandescent lamps is only 1000 hours, and the typical life of compact fluorescent lamps is 8000-10000 hours.
