What are the types of lighting sources, types and characteristics of lighting sources

According to the division of light sources, there are four kinds of lamps that are more common in daily life incandescent lamps, energy-saving lamps, metal halogen lamps, LED lamps (light emitting diodes). These lamps have their own advantages and disadvantages in use, and it is necessary to fully understand the performance of various lamps.

Incandescent lamp

The biggest disadvantage of incandescent lamps is their short lifespan, which is generally between 3000 and 4000 hours. Some incandescent lamps of poor quality can only be used for 1500 hours. Incandescent lamps in homes are often used in dining rooms, bedrooms, and other spaces, and the colors look more comfortable.

Advantages small light source, with a wide variety of lampshade forms; large versatility, many color varieties, with orientation, scattering, diffusion and other forms; can be used to enhance the three-dimensional sense of objects, the color of incandescent lamps is closest to sunlight color.

Disadvantages Not environmentally friendly. When using incandescent lamps, 95% of the electrical energy is spent on heating. Only 5% of the electrical energy is truly converted into visible light; the heating temperature is high, the thermal evaporation is fast, and the life is short (1000 Hour), high infrared content, easily affected by vibration, low color temperature, yellowish.

Scope of application home dining room, bedroom.

Metal halogen lamp (tungsten halogen lamp)

The metal halogen lamp is actually a kind of incandescent lamp, and the life span is generally between 3000 and 4000 hours, and will not exceed 6000 hours. This kind of lamp can be used for accent lighting. For example, in order to highlight the decorative painting on the wall, indoor decorations, etc., it can be illuminated with a cold light lamp cup. The white light of the lamp can be changed according to different home decoration styles, keeping it consistent with fashion.

Advantages simple, low cost, easy to adjust and control brightness, good color rendering.

Disadvantages short service life, low luminous efficiency, filaments are prone to fuse at high temperature for a long time, and the failure rate is high.

Scope of application car headlights and rear lights, and homes, offices, office buildings, etc.

  

Fluorescent lamp

Advantages energy saving, about 60% of the electrical energy consumed by fluorescent lamps can be converted into ultraviolet light, and other energy is converted into thermal energy. Generally, the efficiency of converting ultraviolet light into visible light is about 40%. Therefore, the efficiency of fluorescent lamps is about 60% × 40% = 24%-about twice the same power tungsten filament lamps.

Disadvantages light decay will occur, the color rendering of fluorescent lamps is not as good as incandescent lamps; the light has flickering, which has a certain impact on vision; in addition, there is mercury pollution in the production process and after use and disposal.

Scope of application factories, offices, schools, supermarkets, hospitals, warehouses and other indoor public spaces.

How Do Motion Sensor Night Lights Work?
Modern plug-in motion sensor night lights use passive infrared (PIR) technology to detect body heat and movement within 10-15 feet. When activated, they instantly illuminate bright LED bulbs (typically 2-10W) without manual switching - creating the ultimate no wiring needed night light solution. Most models feature:



Adjustable sensitivity (for pets/children)



Time-delay settings (15sec to 10min operation)



Twilight sensors (only activate in darkness)
