How to solve the heat dissipation problem of LED outdoor solar road stud lighting light source? The main factors of the heat dissipation scheme of LED outdoor solar road stud lighting light source are as follows: the use of LED outdoor solar road stud lighting light source under the condition of no overheating can greatly prolong the service life. Generally, it is made of aluminum alloy, which is easier to dissipate heat. That is, the LED outdoor solar road stud lighting source is pasted on the aluminum substrate to maximize the external heat dissipation area.
Working over the rated current for a long time will greatly shorten the service life of LED beads for LED outdoor solar road stud lighting. The constant current power supply for LED outdoor solar road stud lighting is to ensure that its working current value remains unchanged when environmental factors such as temperature and voltage change.
Constant current accuracy of LED outdoor solar road stud lighting power supply. Generally, it is required that the constant current accuracy difference of LED outdoor solar road stud lighting is ± 3%. Produce LED outdoor solar road stud lighting according to 3% of the design scheme. The LED outdoor solar road stud lighting power supply should be fine-tuned to achieve ± 3% error. The lighting error of LED outdoor solar road stud is too large, resulting in appliance failure.
The efficiency of LED outdoor solar road stud lighting light source should not be too low, otherwise the heat consumed on the light source is too large. The efficiency of non isolated type is higher than that of isolated type, which is generally more than 80%. However, the efficiency is also related to other factors of LED outdoor solar road stud lighting.
