Today we will talk about the power of lamps. The final power of all lamps must be tested according to the electrical power meter. Let's take an example. 18 15W lamp beads are used in a waterproof parquet lamp. Due to heat dissipation problems, we need to control the overall temperature of the lamp below 60°C, which will reduce the driving current of the lamp beads and change the overall lamp. Rated power. Of course, the specific reduction depends on the configuration and heat dissipation conditions of the lamp itself.
If the lamp bead ceramic base, copper thermal base, plus high thermal conductivity aluminum substrate, PFC power supply, motherboard IC, MOS and other electronic components are all made of high temperature resistant chips. The LED par lamp has an external waterproof fan to assist in heat dissipation, so the heat dissipation is good, the lamp is relatively better protected, and the light decay of the lamp bead is reduced. Secondly, configuring temperature control is also a means to protect the lamps. Generally speaking, the power of the lamps stabilizes after one hour of lighting. We take a power test meter and we can know the total power of the entire lamp. Rather than multiplying the number of lamp beads by the power of a single lamp bead. For example: the total power of 18 15W modules is 18x15=270W. This is the wrong calculation method. The correct one must be based on the test results of the power meter.
Many people mistakenly believe that the more lamp beads, the higher the power of the entire lamp, ignoring the maximum heat dissipation capacity of this lamp. The temperature of electronic appliances cannot exceed 60°C. Take a par light as an example. Its power is determined by its heat dissipation capacity. The heat dissipation of more aluminum materials is definitely better than that of less aluminum materials. It is not simply based on the number of lamp beads x the power of the lamp beads.
Pls check the above lamps, which one has the highest brightness?
