What Are the Advantages and Disadvantages of 0603LED

What are the advantages of 0603LED lamp beads? 1. The size of the packaging seal is small: the LED is a small chip and is packaged in epoxy resin, so it is very small and light, the size of the 0603 series LED is 1.6* 0.8mm, suitable for precision products to use; 2. High brightness: Low -calorie LED uses cold lighting skills, which is much lower than ordinary lighting fixtures. 3. 0603 LED chip can use the principles of red, green, and blue. Under the control of computer technology, the three colors have 256 gray and mixing. 4. Low power consumption: 0603 LED light voltage is between 1.8-3.4V, the current is 5mA-20mA, and the power is very small about 0.02W. 5. The light focus can be strong: the luminous point of 0603 is more concentrated, and the effect is slightly better. 6. Environmental protection LED is made of non -toxic data. Unlike the fluorescent lamp containing mercury, it will constitute purification. Where is its shortcomings? Affect vision: The most unacceptable human eye is 0603 Blu -ray and UV purple light. Blu -ray kills human eye activity cells about 10 times the green light, UV purple light cells are 10 times the blue light. Active cells are a small amount, and the final cancer constitutes a plaque. And the LED white light composition is to rely on the 450-455nm wavelength blue light to arouse fluorescent powder. The lower the wavelength, the stronger the hairpot. Usually the wavelength of the LED is controlled within 500nm, that is, 450-455nm, or 455-460nm, which is the most damage. Strong interval, assuming that the wavelength becomes larger, then the talent of fluorescent powder landed, and the efficiency is reduced. In order to pursue brightness, people usually strengthen the Blu -ray intensity of LED 0603. The longer the lighting time, the faster the fluorescent powder attenuity, which will cause the light of the blue light band of people's eyes to be more severe.
