Color temperature is a physical quantity that describes the color of a light source, usually in Kelvin (K). The color temperature represents the degree of warmth or coolness of the color tone of the light source. Color temperature is defined by simulating blackbody radiation.

For track lights, the bulb is one of the key factors that determine its lighting effect. With the popularization of LED technology, more and more track lights have begun to use LED bulbs as light sources because LED bulbs have the advantages of high energy efficiency, long life, low heat, and environmental protection.

Aluminum alloy is a very suitable material for outdoor lighting fixtures, especially outdoor wall lamps. Its advantages include: ● Corrosion resistance ● Weather resistance ● Lightness ● Machinability Ordinary iron is often not recommended for outdoor lighting for the following reasons: ● Corrosion resistance ● Insufficient strength

Pros of LED recessed downlights: 1. Energy-saving and high efficiency 2. Modern and simple appearance design 3. Uniform light effect and reduced glare 4. Flexible installation methods 5. Adapt to a variety of scenarios and needs Cons of LED recessed downlights: 1. High installation requirements 2. Inconvenient maintenance 3. Restrictions on light adjustment 4. High cost

Although the LED chip itself requires direct current to work properly, most home and commercial power systems provide alternating current. Therefore, when the LED lighting downlight is working, it needs to convert the alternating current into direct current through a power driver module.

LED itself is a point light source with strong divergence of light. In LED spotlights, through reasonable optical design and the role of lens or reflector, the propagation direction of light can be changed and the divergence of light can be reduced, thereby focusing the light beam to a specific area.

LED track light has a wider beam. Although it can adjust the direction and angle of illumination, its beam concentration is lower than that of spotlights. It is mainly used to provide uniform lighting effects and is suitable for large areas. lighting needs.

● 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.
