1. Intelligent control is one of the advantages of LED lamps, and power supply is the key to intelligent control.
Smart control has the most mature conditions in LED street lighting and LED tunnel lighting applications. Intelligent control can achieve stepless control of lamp power according to road traffic density at different time periods. It not only meets application requirements, but also achieves huge energy savings. The effect can save a large amount of funds for highway authorities. The application of tunnel lighting not only can save energy, but also can automatically adjust the brightness of the tunnel entrance in accordance with the brightness outside the tunnel, to provide the driver with a visually excessive stage to ensure driving safety.
2. Give up high-power, ultra-high power, and choose a medium and low-power power supply with high stability.
Because the greater the power, the greater the amount of heat, and the more compact components inside, is not conducive to heat dissipation, and the temperature is the culprit of the power supply failure. Furthermore, the development of relatively low-power power supplies is relatively mature, with advantages in both stability and cost. In fact, many high-power power solutions have not been time-tested and proved by practice. All of them are rush-start projects and are experimental products. As a result, there are many kinds of faults. In contrast, due to the earlier development of small and medium-sized power supplies, the technical solutions must be mature.
3, heat dissipation and protection are the main external factors of power failure.
Not only does the power supply itself generate heat, but also the lamps can heat up. How these two heat sources are emitted properly is a problem that must be considered by the lighting design engineer. It is necessary to prevent over-concentration of heat, create a heat island effect, and affect the life of the power supply. Using a split power scheme is a good choice.
4, the feasibility of maintenance.
The problem of power supply failure cannot be completely avoided. Chengdu Chaoyue Optronics has proposed the principle of simple maintenance. Only when the replacement of the power source is replaced with the light source of the conventional lighting is so simple, can the user be happy, even if the power supply is broken, the mood will not be bad, and the user's mood determines the LED lamp manufacturer's fate.
5, protective performance.
The protection problem is also very important. The penetration of moisture may cause a short circuit in the power supply. The dust on the enclosure will affect the heat dissipation of the power supply. Exposures can easily cause high temperatures and aging of wires and other components. From the experience in practical use, the rotation The wiring plug has a higher failure rate, and most of the leaks cause malfunctions.
6, modular design.
Modular design has become the current trend. It is necessary to think of ways to integrate the module power supply. If the power supply can be used to solve the maintenance problem, it will be welcomed by users. At the same time, it needs to establish interface standardization, so that different manufacturers LED lamp power supply can be used universally.
7, give up more than 4 output, the development of single or two output, give up large current and large current, the development of small current.
The more and more complex the number of output channels, the higher the cost of current interference between different outlets, and the higher the failure rate if they are not resolved. In addition, the greater the number of output channels, the greater the total output current. The current is the main cause of heat generation. The voltage itself does not directly lead to heat generation. In simple terms, the heat output is proportional to the square of the current, that is, the current increases to the original value. At 2 times, the calorific value will increase to 4 times the original, the current will increase 3 times, and the calorific value will increase to 9 times. In summary, the failure rate of single- or dual-output LED lamps will be much lower.
Through the above seven-point summary, the manufacturer will be more convenient when designing the LED driving power. Work will save time.
Lead Acid vs. Lithium: Safety
Safety is always a primary consideration when designing a solar system, but it becomes even more important when your system is on a boat far from shore, or an RV on a remote road. Different battery chemistries have different risk factors. Obviously, abusing any type of battery can create a dangerous situation. But with normal, and perhaps even a bit of rough treatment, the different batteries have different safety concerns that need to be addressed.
- Flooded lead acid batteries have an acid and water electrolyte in the battery that has to be checked on a regular basis. During normal charging cycles, this mixture turns into a gas that needs to be vented outside. A buildup of the gas inside a vehicle or vessel can be explosive. Proper ventilation mitigates this concern. The outgassing of the battery is normal, but requires owners to regularly check to see when the electrolyte level gets low from the outgassing. If low, it needs to have more distilled water added. This runs the risk of acid spills if overfilled or overcharged. This requires you to be prepared with proper safety equipment including gloves, safety glasses, and baking soda to neutralize the acid if needed.
- Sealed lead acid batteries do not have outgassing or electrolyte levels to check, as they do not outgas. Normal battery safety measures should be followed, like checking for tight cable connections, corrosion, and preventing physical damage to the battery itself.
- Lithium batteries also do not outgas, but certain types (the ones with cobalt, known as lithium cobalt oxide or LCO) can experience thermal runaway – a condition where the battery starts to get hot, which causes it to react to the heat and get hotter and hotter until it catches on fire. LCO batteries are most commonly used in cell phones, hoverboards, and electric cars, and are generally not recommended for mobile applications.
