What are the factors that affect the brightness of LED lamp beads?
When ordinary people use headlights, flashlights and other items, they always want to be brighter. If you want to have a bright spot, in addition to having sufficient battery power, you also need to work on the lamp beads. As a LED lamp bead manufacturer, today we will learn from the lamp bead level with you. Let's take the flashlight lamp bead as an example. Which LED lamp beads are the brightest? What are the factors that affect the brightness of LED lamp beads?
There are two types of lamp beads for flashlights: plug-in and SMD LED lamp beads. These lamp beads have different models and have different powers. We have referred to some existing high-brightness flashlights and found that there are many high-power lamp beads that use SMD, such as 3535 5W, such as high-power 3W SMD, all of which are used. Therefore, it is necessary to understand which kind of LED lamp beads have high brightness and what factors affect the brightness of LED lamp beads. We believe that the same type and same power LED lamp beads are required to rank. For example, the brightness ranking of in-line led lamp bead bullets, round heads and straw hats will be different. why? Under the same power, the brightness and light power are related to the light intensity per unit area. The light intensity and brightness are related to the luminous surface and power. For example, the same 5mm in-line lamp beads are 0.06 watts, and the brightness of the same chip lamp beads is brighter than that of the same power 5mm round head and straw hat lamp beads. Why? Because of the same chip, the light-emitting angle of the bullet head lamp beads is the smallest, only about 15 degrees, and the round head is generally 45 degrees or 60 degrees, and the straw hat lamp beads are 100-120 degrees. Therefore, for the same power lamp beads, the brightness ranking is that the bullet head is brighter than the round head, and the round head is brighter than the straw hat lamp bead. This brightness judgment standard is determined according to the angle under the same conditions as the power chip.
In addition, the brightness ranking of flashlight beads. For example, the same 3535LED lamp beads, 5W lamp beads are brighter than 3W ones, and 3W ones are brighter than 1W ones. This brightness is related to the power level. Why? The same light-emitting angle of 120 degrees flat angle, 3535 1W, 3535 3W, 3535 5W. The greater the power, the greater the brightness. Therefore, the ranking is to rank according to the power size.
In general: There are many ranking methods for the brightness ranking of led lamp bead models. But no matter what, it is generally the same power, the same chip size, and ranked according to the angle. At the same angle, the brightness is ranked according to the power, and of course, according to the package type. For example, the imitation lumen 3W is brighter than the conventional SMD 3W lamp beads. Of course, there are also positive polarity lamp beads and reverse polarity lamp beads, and the brightness ranking of colored light lamp beads. Therefore, you want to know the brightness ranking of led lamp beads, the brightness ranking of flashlight led lamp beads, how did you choose, and what products are you going to use. Most people do it themselves with reference to others. In fact, you can also find LED lamp beads manufacturers to help you choose. Arranged according to brightness.
