LED wall lamps are wall-mounted lighting fixtures that use LED light sources. LED (Light Emitting Diode) is a semiconductor light source that can convert electrical energy into light energy through the flow of electrons. Compared with traditional incandescent lamps, fluorescent lamps, etc., it has higher energy efficiency and longer service life.

Traditionally, LED lamps are usually controlled by manual switches. The existence of a switch allows users to easily turn on or off the lamp when needed, ensuring the convenience and energy saving of lighting. In this case, the switch is usually installed near the entrance, such as the kitchen door or next to the cabinet, so that users can easily operate it manually.

LED spotlight is a spotlight that uses LED (light emitting diode) as the light source. Compared with traditional light sources such as halogen lamps and incandescent lamps, LED spotlights have higher luminous efficacy, longer service life and lower energy consumption.

"Surface-mounted" refers to the installation method of the lamp, that is, the lamp is directly exposed on the ceiling or wall surface, instead of requiring reserved space or embedded in the wall like recessed lamps. A surface-mounted LED downlight is a lighting fixture with a circular cylindrical shape and an LED light source.

If the output signal of the dimmer is unstable or not suitable for LED panel lights, it may cause the lamp to flicker. Frequent flickering will not only affect the user experience, but may also cause a load on the internal circuit of the lamp and shorten its service life.

The human activity range is an important basis for determining the installation height. Generally, the sensor night light needs to capture the movement of a person's legs, waist or arms. Therefore, the most common installation height is between 0.3 meters and 1.5 meters from the ground.

When making the final decision, users should consider their specific needs. If it is mainly used for daily makeup, warm light may be more suitable; if fine eye makeup and eyebrow shaping are required, cool light may better meet the needs. Environmental factors will also influence the choice.

If you want the light in the bedroom to be softer and more uniform, and provide a comfortable sleeping environment, LED downlights are undoubtedly a more suitable choice. If you need to highlight certain decorative details or local areas in the bedroom, LED spotlights can provide more precise lighting.

Passive infrared sensor is the most common type of motion sensor night light. It determines whether there is motion by detecting infrared radiation emitted by objects. PIR sensors are sensitive to temperature and can detect infrared radiation from objects with higher temperatures such as human bodies. In contrast, cold-blooded animals or objects with small temperature differences (such as furniture) are not easily detected.

Advantages of surface mount LED lights: 1. High efficiency and energy saving 2. Long life and low maintenance cost 3. Compact design and flexible installation 4. Green and environmentally friendly with no harmful substances 5. Instant light on and no flicker Disadvantages of surface mount LED lights: 1. Higher price 2. Overheating problem 3. Limited light distribution 4. Not applicable to all locations

Once the motion sensor detects a change, it sends a signal to the control unit. After receiving the signal, the control unit starts the light source unit. The light source unit starts to emit light to provide sufficient lighting.
