Shopping guide for deep UV LED beads

When it comes to deep UV LED lamp beads, many people may not be unfamiliar with it and don't know how to buy it. Today we'll talk about its features and purchase details

Deep UV LED product features:

◆ high light output power;

◆ long service life and low light attenuation;

◆ environmental protection, energy saving and high reliability;

◆ durable, impact resistant, easy to design, suitable for application in many fields

1. When buying, we should first start with brightness. Due to different brightness, the price will vary. The products used for LED lamp beads shall meet the first-class specification of laser grade, and the anti-static ability can not be ignored. The stronger, the longer the life, the higher the natural price.

2. Generally speaking, the color of lamps with the same wavelength will be consistent, so it is difficult for manufacturers without LED color splitter to ensure the purity of product color. Other, because LEDs are unidirectional conductive semiconductors, if there is a reverse current, it will become leakage. The LED with large leakage current has short service life and low price.

3. Different luminous angles will also affect the concave convex of the price. Therefore, when buying, you might as well see if it is a full diffusion angle. If so, the price will be higher. The prices of other different chips vary greatly.

4. The origin of the chip affects the price of the product to a certain extent, but also selects the quality problem. Therefore, at the time of purchase, the user can recognize the uneven quality of the product through the chip used on the LED lamp. Therefore, understanding the chip supplier can roughly recognize the price range of LED lamps, which is one of the useful ways for experienced buyers to comment on suppliers.

How to detect the quality of deep UV LED beads?

The red probe of the multimeter is in contact with the anode contact of the lamp bead, and the black probe of the multimeter is in contact with the cathode contact. Observe whether the light is on. If the lamp is on, it indicates that the basic function of the lamp bead is normal. If it doesn't light up, replace the red and black probe and retest. In order to avoid that the cathode and anode of some lamp beads are opposite to those of general lamp beads.

Look at the luminous angle: the luminous angles of LEDs for different purposes are different. Special lighting angle, higher price. Such as full diffusion angle, the price is higher. Generally speaking, the quality of domestic LED lamps is lower than that of imported lamps. Therefore, when purchasing LED lamps, you need to observe the light source of LED lamps.

If a digital multimeter is used, a diode measuring block can be used to measure the positive and negative poles of the LED bulb. If a pointer multimeter is used, use 10K Ω mode for measurement. After opening, you can intuitively see that the LED bulb is slightly bright, which is a good LED bulb, otherwise the bulb may be broken.
