If the heat dissipation design of LED lamps is poor, the high temperature of LED chips will accelerate their aging. High temperature will cause electron migration inside the chip, which will reduce its luminous efficiency and eventually lead to brightness decay.
When choosing LED lighting fixtures, consumers should focus on lumens rather than watts. Lumens more directly reflect the brightness of the lamp, while watts are mainly used to reflect the energy consumption of the lamp. Understanding the difference between the two can help consumers make more appropriate purchasing decisions.
According to the principles of physics, the greater the current, the more times the electrons and holes in the LED recombine, and the more light energy is generated, so the LED will appear brighter. For standard LED bulbs or LED panel lights, the relationship between brightness and current is usually linear - that is, the current increases, the brightness increases.
Generally speaking, the length of the vanity wall light is recommended to be no more than 1/3 of the dressing table. Specifically, for a 72-inch dressing table, a wall light with a length between 24 and 36 inches (about 61 to 91 cm) can be selected.
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.
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.
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.
