LED Lamp Beads Buy Three LED Lamp Beads for Big Misunderstandings

Misunderstanding first, the hope of the actual service life is high, LED lamp bead manufacturer expects the LED lamp bead life to reach 100,000 hours. However, just like all basic light sources, the light flux of LED lamp beads has also decreased over time. Therefore, although the lighting time of LED lamp beads can be very long, MTBF is not the only consideration for determining the service life. The decay of LED lamp beads is affected by many environmental conditions such as environmental temperature, humidity and ventilation. The influence of lingering attenuation is also affected by controlling, thermal science governance, the degree of current, and the consideration of many other electrical design. Many salespersons may provide some information to customers when selling LED lamp beads, causing misleading, like the service life of LED lamp beads in 100,000 hours. The 100,000 hours here means that the manufacturer expects LED Lighting life life. However, as a light source of lighting, the brightness of the lights has a process of gradually decaying darker (such as sunlight, energy -saving lamps). This process is referred to as light decay. Therefore, when consumers buy LED lamp beads, they should pay attention to its light atance rate, not use time, and consumers will not expect the actual life expectancy. Misunderstanding 2, divide the actual light angle as a useful angle of LED lamp beads into a useful angle and actual light -emitting angle. The purpose of the target value of the axial strength value of the light -emitting intensity is a useful angle with the angle of the light emitting axial (method). Two times the angle of the half -value angle is the perspective (or the semi -power angle) is the actual lighting angle. From the angle of the axial strength half because the light is too weak in the actual application, it does not count on the useful angle. Therefore, consumers should pay attention to the actual lighting angle of the product when buying products. When calculating the number of products used in the project, it is based on the actual lighting angle. Misunderstanding 3, the higher the brightness, the higher the brightness of the LED lamp beads with the light emitting intensity, and the light emitting intensity refers to the light emitting intensity of the target of the method line (to the cylindrical luminous pipe refers to its axis) The light flux is candlelight (CD). Because the luminous intensity of general LED lamp beads is small, the light emitting intensity often uses the units. Generally speaking, the light source will radiate its optical flux to the different target of the Domestic LED lamp beads with different strengths. From the perspective of how many work do the power in the same time, the current is fast, the current is fast, the electricity is the age of power; the current is slow, the electrical power is small, or the more the current does the current, the more the electricity is, the more the electricity. On the LED lamp beads, the higher the power, the higher the brightness of the product. Taking the three light red LED lamp beads of Yimei Electronics as an example, when the axial brightness is 1200mcd, the current is 40mA and the power is 0.48W; It can be seen that the power of the two lights under the brightness of the light is different. Therefore, when consumers buy LED lamp beads, they must pay attention to its axis brightness, not power. The article comes from LED lamp beads http://.
