Why do light bulbs not produce the same quality?
Due to wear and tear of appliances over time, things such as lights will not always produce the same quality output. As light bulbs are used, and wear and tear kicks in, the light bulbs will produce less and less light. When this happens, it is recommended that the light bulbs be replaced.
Why are LED lights dim?
LED lights are dim due to improper maintenance. The service life of LED lamps is not only related to the quality of the lamps, but also to the maintenance of the lamps. The dust behind the LED lamps should be cleaned with a dry cloth or a ladle.
How to increase the brightness of LED lights?
If you want to increase the brightness of the LED lamp, you can change the brightness of the LED lamp by adjusting the resistance of the current sampling resistor in the driving circuit. The brightness of the LED lamp can be changed by adjusting the resistance value of the resistor connected to the CS pin of the constant current drive device HV9910 as a current sampling resistor. Generally, reducing the resistance value of the resistor appropriately can improve the brightness of the LED lamp. On the contrary, increasing the resistance value can reduce the brightness of the LED lamp.
What is the quantum efficiency of phosphor?
Phosphor: The quantum efficiency of the phosphor (intuitively expressed as brightness). The higher the quantum efficiency, the higher the light efficiency of the LED device. Increasing the quantum efficiency of phosphors will usually be accompanied by an increase in particle size.
How does silica gel affect light efficiency?
The different light extraction rates of silica gel indirectly affect the light efficiency due to the different refractive index. The higher the refractive index, the higher the light extraction rate. In addition, the quality of similar gold wires, primers, and silver glues will affect the conductivity due to their effects on conductivity and thermal conductivity.
