What are the functions of the lamp and what are the uses of the lamp

Lighting: life (street lamp), study (desk lamp), room lighting (incandescent lamp), carry lamps (flashlights) to beautify the environment: such as neon lights, landscape lights.

Signals: contact lights, signal lights, indicator lights (lighthouses, traffic lights), warning lights (emergency lights). Car Lights:

Turn signals, lights, brake lights. Explosion Proof Lights: Special Occasions.

The main ways to use light signals:

1. Flash distress signal: Find a thing that can block the light source (boards, books, newspapers, clothes) and cover it on the light source (flashlight, lamp head, wax candle, lantern), aim at the place where there may be people, and make the light intermittent by moving the cover. The flash signal emitted in this way appears to be a flashing light from a distance.

If you know the language of lights, and the other party is also a skilled lamp hand, you can even chat through the lights.

2. "SOS" signal history: The standard distress signal of "SOS" can also be issued with lights, that is, three short flashes, three long flashes, and then three short flashes.

3. Red circle: cover the light with red cloth and red paper to make the light source emit red light, and wave your arm to draw a circle where there may be people.

4. Automobile emergency signal: the flashing lights on both sides flash at the same time - double flashing, double flashing is the emergency signal of the traffic department and the driver's general knowledge. In the event of a car breakdown and traffic accident, turning on the double flash is a warning and a call for help. All vehicles are now equipped with dual flash buttons.

5. "Fool" signal: If you don't have any knowledge of light signals, you can (in fact, you have to) think like this: even if I understand the light language, the other party may not necessarily have common sense in this regard.

Then, in the dark night, especially in the wild, using light sources to flicker and flash can attract the attention of others.

Lighting fixtures consist of a lighting source, a lampshade and an accessory.

1. Lighting fixtures are divided into two categories according to their functions: decorative lamps and functional lamps.

1. Decorative lamps and lanterns are composed of decorative parts and lighting sources, in addition to properly considering the requirements of lighting efficiency and glare prevention, they mainly meet the needs of architectural art with beautiful appearance.

2. The function of functional lamps is to redistribute the luminous flux of the light source, improve the efficiency of light utilization and avoid glare, and create a suitable light environment. Special lamps used in humid, corrosive, explosive, flammable and other environments, the lampshade also plays a role in isolation protection.

2. Lighting fixtures are divided into two categories: indoor lighting fixtures and outdoor lighting fixtures according to the place of use.

1. Indoor lighting fixtures are usually classified according to the distribution ratio of total light in the upper and lower hemispheres of the space. According to this, the International Commission on Illumination suggested that lighting fixtures should be divided into five types: direct, semi-direct, uniform diffusion, semi-indirect and indirect.

The following table shows the light distribution and lighting characteristics of different types of luminaires:

2. Outdoor lighting fixtures, mainly floodlights. Floodlights, also known as projectors, use reflectors, transmissive mirrors and grilles to confine light in a small solid angle to become a strong light source, often used in large building night lighting.

<>1. Ordinary incandescent lamp: used in living rooms, living rooms, lobbies, guest rooms, shops, restaurants, corridors, conference rooms, and courtyards. It is characterized by good color rendering, light on, continuous dimming, simple structure, low cost, short life and low light efficiency.

2. Tungsten halogen lamp: used in conference rooms, exhibition halls, living rooms, commercial lighting, film and television stages, instrumentation, automobiles, airplanes and other special lighting. It is characterized by more than double the light efficiency and service life of ordinary lighting incandescent lamps, and is small in size.

3. Fluorescent lamps: Fluorescent lamps have straight tube type, ring type, compact type, etc., and have a wide range of energy-saving lighting sources. It is characterized by high light efficiency, long life and good light color.

4. Low-pressure sodium lamp: used in tunnels, ports, docks, mines, etc. It is characterized by high luminous efficiency, long life, high luminous flux maintenance rate, and strong fog permeability, but poor color rendering

The functions of the lamp are:

1. Home lighting fixtures, including craft chandeliers, wall flower lamps, decorative table lamps and light bars, etc.

2. The old and lacking commercial office lighting fixtures can be divided into flat lights, downlights, bracket lights, grille lights, ceiling lights, etc.

3. Engineering lighting fixtures, including road lamps, tunnel lamps, flood lamps and ICBC factory lighting.

4. Decorative lighting fixtures are used for urban night lighting, including various wall washing lamps, point and line lights, waterscape lighting and festival lights.

5. Special local lighting fixtures are divided into visual work desk lamps, spotlight lamps and searchlight lamps.

6. Special signal lamps and lanterns can be divided into road traffic signal lights, marine signal lights, railway traffic lights, airport navigation aids and aviation obstruction lights.
