What are the lighting sources? What light source is good for home decoration lamps?
In daily home life, lamps and lanterns are indispensable, and there are many kinds of light sources of lamps and lanterns, and the light color must be considered when choosing, because different light sources bring different feelings, so what are the lighting sources? ? What light source is good for home decoration lamps? Many people don't know it well, don't worry, let's explain it to you with BENWEI LIGHTING. Let's take a look.

What are the lighting sources?
1. Incandescent lamp
The biggest shortcoming of incandescent lamps is their short life span. The operating time 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 spaces such as dining rooms and bedrooms, and they look more comfortable in color.
2. Tungsten halogen lamp
The metal halide lamp is actually a kind of incandescent lamp, and the life span is generally between 3000 and 4000 hours, not more than 6000 hours. This kind of lamp can be used for accent lighting. For example, in order to highlight the decorative paintings on the wall, indoor decorations, etc., it can be illuminated with cold light cups. The white light of the lamp can be changed according to different home decoration styles, and it is consistent with fashion.
3. Fluorescent light
Energy saving, about 60% of the electric energy consumed by fluorescent lamps can be converted into ultraviolet light, and other energy can be converted into heat energy. Generally, the efficiency of converting ultraviolet light into visible light is about 40%. Therefore, the efficiency of a fluorescent lamp is about 60%×40%=24%-approximately twice that of a tungsten lamp with the same power.
4. Energy-saving lamps
Energy-saving lamps are popular because of their energy saving. A 9-watt energy-saving lamp is equivalent to a 40-watt incandescent lamp. The life of energy-saving lamps is also relatively long, generally 8000 to 10000 hours. After a period of normal use of energy-saving lamps, the lamp will dim, mainly because of the loss of phosphor, which is technically called light decay. Some high-quality energy-saving lamps have invented constant-brightness technology, which can keep the lamp in the best working condition for a long time. After 2000 hours of use, the light decay is less than 10%.
5. LED lights
The scientific name of this kind of lamp is light-emitting diode, which is a new technology. The white LED lights on the market now have better performance, but the current LED lights still need to be improved technically.
Lamps
What light source is good for home decoration lamps?
1. LED lights
The advantages of LED lights are small size, low power consumption, long life, non-toxic and environmentally friendly. The disadvantage is that it needs constant current drive, and the heat dissipation is not good and it is easy to light decay. The light effect is relatively low, and the color will be missing.
Luminous efficiency: 60～120lm/w; Service life: 30000-50000 hours; Market price: The price is relatively expensive.
LED light purchase: look at solder joints, FPC quality, cleanliness, packaging, labels, accessories, etc.
2. Energy-saving lamps
Energy-saving lamps have the advantages of small size, energy saving, and longer life than incandescent lamps. The disadvantage is that the color rendering index is low, which will cause serious discoloration when looking at things; it is fragile and mercury is added, which pollutes the environment, and the ballast generates a certain amount of electromagnetic radiation when it generates instantaneous high pressure.
Luminous efficiency: 50-100lm/w; service life: 8000 to 10000 hours; market price: cheap.
Energy-saving lamp purchase: choose the authoritative certification mark, look at the package, model, appearance, and interchangeable lamps.
3. Fluorescent light
It is also called a fluorescent lamp, which has the advantages of energy saving and many colors. The disadvantage is that the color rendering is relatively poor, and harmful elements such as mercury are harmful to the environment. In addition, ultraviolet radiation and strobe damage the eyes.
Luminous efficiency: 40~60lm/w; service life: 3000~4000 hours; market price: relatively cheap.
Fluorescent lamp purchase: see specifications, appearance coordination, lamp color, label, manual, etc.
4. Halogen lamp
Commonly known as lamp cups, cup lamps, spotlights, halogen gases such as iodine or bromine are injected into the bulb. At high temperatures, the sublimated tungsten wire reacts with the halogen, and the cooled tungsten will re-solidify on the tungsten wire to form a balanced cycle. Simple, low cost, easy to adjust and control the brightness, and good color rendering. The disadvantage is that the service life is short, the luminous efficiency is low, and the filament is prone to failure under high temperature for a long time.
Luminous efficiency: 19-21lm/w; service life: between 3000 and 4000 hours; price range: medium.
5. Incandescent lamp
Composed of tungsten wire, glass bulb and lamp cap, the advantage is that all lamps have the best color rendering, which is the closest to natural light, and the price is very cheap. The disadvantage is that it consumes a lot of power and has a short lifespan. Most of the electric energy is used for heating, and its performance is low. It has been basically eliminated by the market now.
Luminous efficiency: 10-15lm/w; service life: generally around 1000 hours; market price: very cheap.

The above is the knowledge of what are the lighting sources and what kind of light sources are good for home improvement lamps. I will stop here for the first time. The content is for your reference only, and I hope it can be helpful to everyone.
