Introduction to garden lamp components
The visible photoelectric radiation produced by the heating of an atom. The incandescent lamp uses an incandescent light emitting principle to let the current pass through the tungsten filament in the vacuum, causing the tungsten filament to heat up to incandescence and give off visible light. Ordinary incandescent lamp color temperature is 2800K, and natural color light yellow, warm. The advantages and disadvantages of the incandescent lamp are low cost, simple and convenient to use and install. Suitable for frequent opening, point out, the performance and life of the lamp are very low.
Fluorescent lamp, energy-saving lamp is a low pressure mercury vapor arc discharge lamp, usually long, at each end of an electrode. The lamp contains mercury vapor with low pressure and a small amount of inert gas, and the inner surface of the tube is coated with phosphor powder. Fluorescent lamps are divided into straight tube fluorescent lamps and compact fluorescent lamps. Straight tube fluorescent lamp according to the starting mode can be divided into preheating start, fast start and instantaneous start several, according to the tube can be divided into T12, T8, T5 several. Compact fluorescent lamps are developed for use in power hungry incandescent lamps with low energy consumption and long life. Ordinary incandescent lamp life is only 1000 hours, compact fluorescent lamp typical life of 8000-10000 hours.
A courtyard lamp is mainly composed of 5 components are: light source is an important part of all lighting products, according to different illumination requirements, can choose different brands, different types of light source, light source commonly used are: incandescent lamp, energy saving lamp, fluorescent lamp, lamp, lamp, Jin Lu ceramic metal halide lamp, as well as new LED light source.
