● SMT: SMT is an electronic component assembly technology that describes the process of directly mounting electronic components (including SMD components) on the surface of a circuit board. ● SMD: SMD refers to surface mount diodes, which is a packaging method for LEDs. It describes the physical packaging form of LED components and is the basis for implementing the SMT process.
In a completely dark environment, the infrared sensor can still activate the night light by sensing temperature changes. Therefore, even in a completely dark environment, a night light equipped with an infrared sensor can work normally, provided that there is an object or human body within the sensing range.
Standard ceiling (2.4-2.7 meters): This is a common height in most homes and offices. At this height, the distance between two LED lamps is generally recommended to be between 1/3 and 1/2 of the width of the room.
Assuming that the wattage of each LED downlight is 10 watts, the number of lamps required is: For a demand of 66.7 watts, the number of lamps required is approximately: 66.7W divided by 10W = 6.7. That is, about 7 10-watt LED downlights are required. For a demand of 111.1 watts, the number of lamps required is approximately: 111.1W divided by 10W = 11.1. That is, about 11 10-watt LED downlights are required.
The three main types of LED track lights include linear track lights, monorail track lights, and cable track lights. These three types of LED track lights have significant differences in structure, installation method, flexibility, and lighting effects.
1. Advantages of LED recessed downlights (1) Energy-saving and high efficiency (2) Long life (3) Simple and beautiful appearance (4) Uniform lighting effect (5) Strong adaptability and flexible installation (6) Low heat and environmental protection 2. Disadvantages of LED recessed downlights (1) Holes need to be reserved for installation (2) Heat dissipation problems (3) Difficult to repair (4) High initial cost (5) Concentrated light source and lack of flexibility
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.
