Practice tells you the difference between 365nm and 395nm purple light beads
It is believed that many people are familiar with the purple flashlight, and the functions of 365nm and 395nm lamp beads are different.
To put it simply:
The light emitted at 365nm basically contains no purple, which does not affect the judgment. The purple color at 395nm is very strong, which sometimes affects the judgment.
The fluorescence at 365nm is generally much stronger than that at 395nm; The fluorescence effect at 395nm is weaker than that at 365nm.
365nm can emit some fluorescence that cannot be emitted at 395nm, such as the fluorescence on the back of people people coins
The left side of the figure below shows the color of a 365nm purple light bulb shining on a white object without fluorescence, and the right side shows the 395nm purple light flashlight effect.
Let's set sail together and meet our original selves!
Life is not only about work, but also about poetry and distance. Body and soul, there is always one on the way. In order to enrich the cultural life of employees and strengthen the cohesion of the company's team, the company organized all employees to go to the scenic Xunliao Bay of Huizhou to run karts, sailing boats, fishing, seafood feast and other group building activities. Through this group building activity, it not only reflects the company's concern for employees, but also enhances employees' feelings for the company. Communication between colleagues enhances the company's team spirit and works together to create a better tomorrow.
The 3030 chip is also a commonly used small size chip luminous source lamp bead, which is mainly white. Like the 5050, it is mostly used in various lamp light sources, point light sources, light strips and other products. 3030 chip led lamp bead parameters [Product type] LED lamp beads [Product series] 3030 patch series [Working voltage] 3.0-3.6V [Working current] 20 MA [Size] 3.0 * 3.0 [Luminous color] White light [Rated power] 1 (W) [Luminous angle] 120 ° [Luminous intensity] 110-140LM [Color temperature wavelength] 7000-11000K
Welding method of LED lamp beads
There are many welding methods for LED lamp beads on the chip, and the following is one of the commonly used methods for reference. First, use an electric soldering iron to heat some soldering tin on the positive and negative electrode pads of the lamp bead (the soldering tin must not be too much, otherwise, the positive and negative electrode pads will be connected once heated with a hot-air gun), then use a hot-air gun to heat the positive and negative electrode pads at the same time, after the tin melts, use tweezers to place the positive and negative electrodes of the lamp bead on the corresponding pad.
