Gauss company uses 42MIL array camera Jingyuan wick, low power, high brightness; heat conduction coefficient is adopted for aluminum plate, 1.1 rapid cooling, to ensure stability; lens with optical lens of Taiwan Institute of optics, fine consistency, efficiency of sending light is currently on the market the highest efficiency.
The difference between dot matrix lamps:
Most people understand that the greater the power, the higher the brightness. That's right. It's only half right.
Power division power and light power, in fact, the greater the light power, the higher the brightness. From the following can be judged which kind of lamp is best: electric power = light power + heat
For example: the electric power 100 units, the light power 30 units, then the heat is 70 units.
The real wafer chip is divided into three levels: low grade 110-130mW, grade 130-160mW and high grade 160-200mW. The average of each level is different, and the average of the 160-200mW level is 165, 170, 180 (highest). Prices vary with different levels.
Other manufacturers have lower chip levels, usually at 90-110mW.
So it's easy to see the difference between brightness and heat from the equation below:
Electric power (unit)
Optical power (unit)
As a result, the lower the chip level, the lower the light efficiency and the greater the heat.
There is another difference in heat difference, that is, the packaging material difference of LED lamp:
Heat Q=I2Rt, this formula shows that the square of the heat and the current, the internal resistance of the lamp, the working time is proportional to.
If the wick current must be, the internal resistance of the lamp is a key factor in heating. The thickness of the gold thread and the material of the support are the key factors to determine the internal resistance. LED bracket copper gold-plated bracket has less resistance, silver plated stent and alloy bracket have greater resistance. The thinner the gold wire is, the bigger the resistance is, and the thicker the resistance is, the smaller the resistance is.
What is the difference between the control panels?:
The control panel should pay attention to the consistency of the output current, the current loss of itself, the quality of the capacitor, and the interference
