  A brief introduction to the design methods and reality of better LED drive power circuits

  For manufacturers, the design of LED driving power supplies is very important. So, how should we better design LED driving power supplies? After a large number of experiments, experts have concluded the following seven tips:

  1. Intelligent control is one of the advantages of LED lamps, and power supply is the key to intelligent control.

  Intelligent control has the most mature conditions and the most obvious effects in the application of LED street lights and LED tunnel lights. Intelligent control can realize stepless control of the power of lamps in different time periods and according to road traffic density, which not only meets application requirements, but also achieves huge energy savings. The effect can save a lot of money for highway authorities. The application in tunnel lighting can not only save energy, but also automatically adjust the brightness of the tunnel entrance and exit according to the brightness outside the tunnel, providing the driver with a visual transition stage to ensure driving safety.

  2. Give up high power and ultra-high power, and choose small and medium-power power supplies with higher stability.

  Because the greater the power, the greater the heat, and the components inside are more compact, which is not conducive to heat dissipation, and temperature is the culprit of power supply failure. Furthermore, low-power power supplies are relatively mature and have advantages in terms of stability and cost. In fact, many high-power power supply solutions have not been verified by time and proven in practice. They are projects launched in a hurry and are experimental products. Therefore, faults occur one after another. In contrast, small and medium-power power supplies developed earlier and their technical solutions are much more mature.

  3. Heat dissipation and protection are the main external factors of power failure.

  Not only the power supply itself will generate heat, but the lamps will also generate heat. How to dissipate these two heat sources reasonably is an issue that lamp design engineers must consider. They must prevent excessive concentration of heat, form a heat island effect, and affect the life of the power supply. Using a separate power supply solution is a good choice.

  4. Feasibility of maintenance.

  Power failure problems cannot be completely avoided, so Chengdu Chaoyue Optoelectronics proposed the principle of simplicity in maintenance. Only when the replacement of the power supply is as simple as the replacement of the light source of conventional lighting, can the user be happy. Even if the power supply is broken, the mood will not be too bad, and the user's mood determines the performance of the LED lamp manufacturer. destiny.

  5. Protective performance.

  Protection issues are also very important. Moisture penetration may cause a short circuit of the power supply. Sand and dust on the casing will affect the heat dissipation of the power supply. Exposure to the sun can easily cause high temperatures and aging of wires and other components. Judging from actual use experience, rotating The failure rate of wiring plugs is high, most of which are caused by water leakage.

  6. Modular design.

  Modular design has become today's trend. We must find ways to integrate modular power supplies. If the power supply can solve maintenance problems by plugging and unplugging, it will definitely be welcomed by users. At the same time, interface standardization needs to be established to allow LEDs from different manufacturers to The lamp power supply can be universal.

  7. Give up more than 4 outputs and develop single or two outputs. Give up large and super large currents and develop small currents.

  The more output channels there are, the more complex it is. It is very costly to solve the current interference between different outlets. If not solved, the failure rate will be higher. In addition, the more output channels, the greater the total output current, and current is the main cause of heat. The voltage itself does not directly cause heat. Simply put, the heat is proportional to the square of the current, which means that the current increases to the original If it is doubled, the calorific value will increase to 4 times, the current will increase to 3 times, and the calorific value will increase to 9 times. To sum up, the failure rate of LED light power supply with single or two outputs will be greatly reduced.
