·IP44 protection level: Applicable to dry areas of the bathroom, such as areas near the washbasin and mirror that are not directly exposed to water. ·IP65 protection level: Applicable to wet areas of the bathroom, such as shower rooms, above bathtubs, and other areas that may be directly exposed to water flow or water vapor. ·IP67 or higher protection level: Applicable to extremely humid environments, such as outdoor bathrooms or places that need to be completely immersed in water.
● LED downlight: Usually embedded in the ceiling, the lamp is not exposed after installation. ● spot light: usually installed independently, the light beam can be directed by adjusting the angle of the lamp. ● track light: installed on a long track, the lamp head can slide freely and adjust the direction.
The power of LED panel light is generally between 10W and 60W, which is suitable for large-area space lighting. The power of LED downlight is usually smaller, mostly 5W to 30W, and is used for local or accent lighting.
Surface-mounted LED downlights usually refer to the lamp itself being exposed and installed on the surface of the ceiling or wall. Unlike surface-mounted LED downlights, recessed LED downlights are designed to embed the lamp as a whole into the ceiling or wall, with only the light-emitting surface of the lamp exposed and the outer shell partially hidden inside the ceiling or wall.
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.
If the lamp uses LED lamps with strong ultraviolet emission, or white and blue LED lamps, it may attract more insects, especially at night or in summer. On the contrary, if the lamp uses red light or warm white light, such lamps will be less attractive and the probability of insects gathering is relatively low.
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.
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.
"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.
