How to choose the right LED light for yourself?

Switching Mode Power Supply

Regular manufacturers use the power supply with PFC. A very important reason is that more than a dozen waterproof lamps are often used in series. In this case, the interference of the power supply may directly affect the signal, causing the occasional random flash of the lamps and other phenomena. Such problems can also be handled with software, but they cannot be completely eliminated. The efficiency of switching power supply with PFC is higher than that of switching power supply without PFC, so the price is more expensive.

Selection of LED lamp beads

Because domestic LED is used by relatively few people due to price factors. Generally, it is only used by large companies, but with the decline of production costs and other reasons (mainly the price of LED beads), popularization is not far away. This is the most important link that affects the cost, life and luminous efficiency of the lamp. Whether a light is good or not, the selection of lamp beads takes up at least 70%.

Workmanship

Large factories and factories with a certain scale have their own chip mounters, and lamp beads are reflowed by chip mounters. However, some small-scale manufacturers apply heat dissipation silicone under the LED lamp beads, which is no problem for short-term use, but the LED has a lot of heat, and your silicone will be dried. In addition, the contact with aluminum substrate does not belong to the kind of direct heat conduction through metal welding, but through the medium of heat dissipation silica gel. Because the heat conduction is relatively slow, the LED of these manufacturers took half a year to show problems, such as brightness attenuation, which is much lower than the brightness of the lamp produced by normal practice.

Lens selection

LED lamps from different manufacturers generally use different lenses, which is related to the luminous angle. The manufacturers who sell lamp beads will have recommendations, but it doesn't mean that the recommended ones must be the best. It depends on the manufacturers' slow testing and repeated exploration.

Circuit design

Obviously, the products of large and professional manufacturers are completely disassembled, usually a control board, a drive board and a display board. Of course, the two-way drive is different. We won't make the control board and the drive board together. After all, one is the thing with high current and the other is the thing with low current signal. Separation is the best anti-interference. However, most small factories outside have no ability to develop their own, so they have to take the circuit boards of professional board manufacturers and install them. It is not that the board manufacturers do not have this technology. They are often the technical backbones of some large factories. But for one thing, their competition is also very fierce, so in order to reduce costs, there is no way to consider these factors. They are facing factories that know nothing about technology and only assemble. Under such conditions, price is the last word.
