As a unique lighting decorative lamp, LED wall lamp plays an increasingly important role in home decoration. It not only provides necessary lighting, but also adds warmth and fashion to the home environment, becoming a new favorite for home decoration. With its unique design and diverse styles, LED wall lamps meet the needs of various home decorations. Whether it is simple and modern or classical and luxurious, LED wall lamps can be perfectly integrated, adding a unique charm to the space.
LED wall lamps with high-quality LED technology emit soft and warm light. In terms of light-emitting principle, energy saving and environmental protection, LED technology is far superior to traditional lighting products. Its spectrum does not contain ultraviolet and infrared rays, does not generate heat and radiation, does not burden the eyes, and does not cause the illuminated objects to fade. For those who don't know much about LED technology, they may ask what is LED? What is the principle of LED light emission? Next, let's explore the mystery of LED together.
What is the principle of LED light emission?
1. Formation of PN junction: The core part of LED is a PN junction composed of P-type semiconductor and N-type semiconductor. P-type semiconductor contains more holes (positively charged carriers), while N-type semiconductor contains more electrons (negatively charged carriers). When P-type semiconductor and N-type semiconductor are closely combined, a special interface, namely PN junction, is formed between them.
2. Carrier injection: When a forward voltage is applied to both ends of the LED, holes in P-type semiconductor and electrons in N-type semiconductor are pushed to the PN junction. Near the PN junction, electrons and holes meet and recombine.
3. Energy release and luminescence: When electrons and holes recombine, they release a certain amount of energy. This energy is released in the form of photons, that is, light is generated. The wavelength (color) of the light emitted by the LED depends on the band gap width of the semiconductor material in the PN junction. Different semiconductor materials have different band gap widths, so they can emit light of different colors.
4. Light propagation and output: The light emitted by the LED will propagate inside the semiconductor material and eventually emit from the surface of the LED. In order to improve the light output efficiency, LEDs usually use some special structures and materials, such as transparent packaging materials, reflective layers, etc.
After understanding the principle of LED light emission, let's take a look at the selection strategy of LED wall lamps.
1. Luminous efficiency
The most important thing about LED wall lamps is the lamp beads inside. The luminous efficiency of the lamp beads is an important indicator to measure whether the LED wall lamp is energy-saving. Generally speaking, the higher the luminous efficiency of the lamp, the more energy-saving it is. When choosing an LED wall lamp, it is recommended to choose a lamp with a luminous efficiency [lumen (lm)/wattage (w)] higher than 80LM/W. Such indicators are in a period of growth. The higher the value, the more energy-saving it is.
2. Color temperature selection to adapt to different environments
Different spaces need to choose LED wall lamps with appropriate color temperatures to create the most suitable atmosphere. Generally speaking, the color temperature range of lamps is 2800~6600K. The smaller the value, the more yellow light it will tend to be, and vice versa, the more blue-white light it will tend to be. Yellow light is more suitable for occasions such as bedrooms and living rooms to create a warm and comfortable feeling. For example, an LED wall lamp with a color temperature of about 3000K can bring a warm atmosphere to the bedroom and make people relax. White light is brighter and clearer, and is more suitable for study rooms, kitchens, etc. In a study room, a color temperature of around 4500K can provide sufficient brightness, making reading and working more comfortable. In addition, when choosing a color temperature, you can also adjust it according to personal preferences and actual needs. For example, some people like cool-toned lights and can choose LED wall lamps with higher color temperatures; while some people like warm-toned lights and can choose LED wall lamps with lower color temperatures.
3. Product quality, attention to details
When choosing an LED wall light, the quality of the product is crucial. First, the heat dissipation performance of the housing component must be excellent. You can consider using a metal material or a housing with a special heat dissipation design, such as an aluminum alloy housing, which has excellent heat dissipation effects. In addition, the quality of the LED lamp beads directly affects the brightness and durability of the wall light. High-quality LED lamp beads can provide brighter light and longer service life. It is recommended to choose XINGLIGHT brand lighting lamp beads, which meet ROHS standards.
LED wall lamps are recommended to use 2835, 3030, 3528, 5730 series lamp beads, ball head 2525, 3535 series lamp beads

Application areas
The application areas of wall lamps are also very broad, such as bars, KTVs, corridors, and e-sports rooms. In hotel lobbies, the uniquely shaped wall lamps can add elegance and atmosphere to the entire space; in restaurants, the soft light of wall lamps creates a warm and romantic dining atmosphere; in study rooms, wall lamps can provide local lighting without producing dazzling strong light, creating a comfortable environment for reading and learning; at the head of the bed in the bedroom, wall lamps are convenient for getting up at night, while also adding a quiet atmosphere to the sleeping space; even in outdoor courtyards and gardens, waterproof wall lamps can also bring unique decorative effects and warm lighting to outdoor spaces at night.
In terms of appearance design, our lamp beads are also unique. The small and exquisite appearance can be perfectly integrated with various styles of wall lamp designs, which will not appear abrupt, but can also add a sense of fashion and technology to the wall lamp. Whether it is a simple modern style, a European classical style or a traditional Chinese style interior decoration, you can find a matching lamp bead application solution.
