When using LED SMD Bulbs, how to optimize the heat dissipation design to extend its service life?
When using LED SMD Bulbs, the heat dissipation design can be optimized from the following aspects to extend its service life:
Choose the right heat dissipation material
Use a high thermal conductivity metal substrate: The metal substrate has good thermal conductivity and can quickly conduct the heat generated by the LED SMD Bulbs. For example, an aluminum substrate is a common choice with a high thermal conductivity and relatively low cost, which can effectively improve the heat dissipation efficiency.
Use thermal conductive silicone grease: Applying thermal conductive silicone grease between the LED chip and the heat dissipation substrate can fill the tiny gap, reduce thermal resistance, and allow heat to be transferred to the heat dissipation components more smoothly.
Optimize the structural design of lamps
Add heat dissipation fins: Designing heat dissipation fins on the lamp housing can increase the heat dissipation area and speed up heat dissipation. The shape, size, and spacing of the heat dissipation fins all affect the heat dissipation effect. Generally speaking, the more fins, the wider, and the moderate spacing, the better the heat dissipation effect.
Adopt convection heat dissipation structure: Design reasonable ventilation channels to allow air to flow freely inside the lamp and remove heat by natural convection or forced convection. For example, open ventilation holes on the lamp housing, or install a small fan for forced heat dissipation.
Control the working environment temperature
Avoid high temperature environment: Try to install LED SMD Bulbs in a place with low temperature and good ventilation, and avoid being close to heat sources such as heaters, ovens, etc. If used in a high temperature environment, consider adding heat dissipation equipment such as air conditioners and cooling fans.
Pay attention to the ambient humidity: A high humidity environment may affect the heat dissipation effect and even cause the internal components of the lamp to be damaged by moisture. Therefore, ensure that the humidity of the use environment is within the appropriate range, and take dehumidification measures if necessary.
Reasonably control the working current
Avoid overcurrent driving: When the working current of LED SMD Bulbs is too large, it will generate more heat, accelerate chip aging, and shorten the service life. According to the specifications of the bulb, select a suitable driving power supply to ensure that the working current is within the rated range.
Adopt constant current drive: constant current drive power supply can keep the working current of LED stable and is not affected by factors such as voltage fluctuation, which is conducive to reducing heat generation, improving heat dissipation effect and stability of bulbs.
Conduct thermal management design
Install temperature sensor: install temperature sensor inside the lamp to monitor the working temperature of the bulb in real time. When the temperature exceeds the set threshold, the control system automatically reduces the working current of the bulb or turns on the heat dissipation device to protect the bulb.
Optimize line layout: rationally plan the line layout of LED SMD Bulbs to avoid excessive concentration of lines, reduce the heat generated by line resistance, and ensure that the heat can be evenly dissipated.
