Lamp type and light source type

1) Luminaire refers to an appliance that can transmit light, distribute and change the light distribution of the light source, and includes all the components required for fixing and protecting the light source except the light source, and the line accessories necessary for connecting with the power supply. The types of lamps and lanterns are extremely rich, with ever-changing shapes and varied performance. Modern lamps include home lighting, commercial lighting, industrial lighting, road lighting, landscape lighting, and special lighting.

2) The light source is an object that can emit light and emit light, such as the sun, an open lamp, and a burning candle. The light sources are mainly generated in three ways: thermal effects (sunlight, candles), atomic emission (fluorescent lights, neon lights) and radiant light (atomic furnace light). Light sources are mainly divided into light sources, radiation sources, stable light sources, and backlights. source.

1 lighting source. For the purpose of lighting, an electric light source mainly emitting light (380-780 nm in wavelength) visible to human eyes is radiated. The lighting sources mainly include incandescent lamps, tungsten halogen lamps, low-pressure gas discharge lamps, high-intensity discharge lamps, gas discharge lamps with large discharge pressure spans, and certain spectral light sources.

2 radiation source. The switch can be turned on by gently pressing the switch button when in use, and the switch is opened when the hand is released. The internal structure of the switch is to be switched on and off by the force of the metal shrapnel. It includes ultraviolet light sources, infrared light sources, and non-illuminating visible light sources.

3 stable light source. Its output optical power, wavelength and spectral width and other characteristics (mainly optical power) should be stable and stable, of course, absolute stability is not possible, but only under given conditions (for example, a certain environment, certain Within the time frame) its characteristics are relatively stable. General automatic power control (APC) circuits and automatic temperature control (ATC) circuits are commonly used to ensure the stability of their characteristics.

4 backlight. By type of light source, the backlight is divided into three types of EL CCFL and LED;. Light source distribution at different positions, is divided into an edge type backlight and a direct type (bottom backlit).

There are a large variety of lamps, and this article only makes a simple classification for their use. There are also many classification methods. For example, according to the category of protection against electric shock, they can be divided into O, I, II, III and III categories, among which the safety of O-type lamps is the worst. Here, the classification methods are not listed one by one.

The invention of an electric light source facilitates the construction of electric devices. Because of its high conversion efficiency, stable power supply, convenient control and use, safety and reliability, and easy instrument/meter counting of energy consumption, it has quickly gained popularity. It not only becomes a necessity for human daily life, but also plays an important role in industry, agriculture, transportation, defense and scientific research.

2)According to daily life accumulation or through Baidu search, understand the classification, characteristics and application of electric light sources.

The basic function of a luminaire is to provide an electrical connection to a light source, must be durable, and provide an electrical, mechanical, and thermal safe housing for the light source and, if necessary, control electrical accessories. Protection of the light source: In addition to electrical connections, the light source must be mechanically supported and protected. The degree of protection is dependent on the requirements. Appropriate mechanical properties: The lamp components must have sufficient mechanical strength to ensure installation and use. With adequate durability, while having sufficient hanging strength, the metal parts must have sufficient corrosion resistance; shell requirements: outdoor lamps must have strict dust and waterproof requirements, while some special requirements for indoor lamps Also provide protection against water and dust. In order to classify the degree of protection of the enclosure based on the degree of protection against dust and moisture, a degree of protection code is used.
