Why Is There a Voltage Difference Between 3V, 6V, 9VLED Patch Lamp Beads?

LED lamp beads are actually a light -emitting diode. After loading a certain voltage and current, it will glow. Generally speaking, the voltage of a single LED chip is about 3V, and the current is 30mA. For the voltage and current of LED lamp beads, most of them are in the process of LED packaging. The 0.2W LED lamp bead used in the lamp tube is made of two LED chips in parallel, that is, 3V, 60mA. For the high -voltage LED 9V lamp beads that are used mostly, the three LED chips are connected in series, that is, 9V, 30mA. Because the LED lamp beads are co -authored by multiple LED chips, there are many specifications of LED lamp beads, and there are many types of voltage. How much is the specific lamp? You can also see how many LED chips are composed of the lamp beads. Of course, because the LED chip is relatively small, the gold thread of the lead key is relatively small. It can only be estimated to visually. You need to test it with DC source. However, it is 3V, 6V, 9V, etc. Of course, there are dozens of V lamp beads. This depends on what kind of lamp beads do you really need to use?. For only 3V lamp beads, you can use a multi -meter diode file to light up this lamp bead. This is positive and negative. For LED lamp beads that do not know the voltage, it can only be measured by DC. From scratch to larger, when the lamp beads are slightly bright, the voltage at this time is the approximate voltage of LED lamp beads. For COB lamp beads, it is actually a principle, but COB encapsulates more LED chips, and the voltage and current will be relatively large. The confirmation method of COB lamps voltage and current is also confirmed by DC source. Each specification of lamp beads have their own characteristics, some are more cost -effective, and some have better performance. The LED lamp beads of the same specifications between each manufacturer will also be different, so the LED lamp beads are not absolutely good or bad. As long as it is used, it will play his biggest role. Professional customization of various LED patch lamp beads. If you need to consult our customer service, we will solve the problem for you.

3528 Infrared Light Beads Are Mainly Used in the Beauty and Physical Therapy Industry
3528 Infrared Light Beads Are Mainly Used in the Beauty and Physical Therapy Industry
The mask beauty instrument is also quite hot in the past two years. There are dozens of lamp beads, and there are thousands of. The advantage is that it can be used directly on the face, and the eye protection structure can also be used. It can also be used for you to swipe and swipe your mobile phone. The disadvantage is that there are some masks, no composite light mode. For example, red, orange and blue are three separate lights, and then the power is relatively low. One is because there are more charging types, and the other is because the large row lights are exposed to 15-20cm interval, and the mask is directly attached to the face on the face. There is no energy loss caused by distance in the middle, so it doesnt need to be very high. The mask on the market ranges from tens of yuan to tens of thousands of yuan, which has a certain relationship with the number, functional model and brand positioning of their lamp beads. 3528 Infrared light beads are mainly used in the beauty and physical therapy industry, including photon rejuvenation instruments, RF radio frequency beauty instruments, hot compress cold therapy instruments, beauty eye meters, red and blue light therapy instruments, large row lamps, phototherapy masks, whitening space compartment, red light, red light, red light, red light, red light, red light, red light, red light Infrared therapy belts, red light infrared therapy insoles, red light infrared therapy mattresses, red light infrared therapy yoga mats, red light infrared neck rivers, red light infrared knees, etc. Zhuhai manufacturers specialize in the production of 3528 infrared light patch lamp beads. New and old customers who need it can come to inquire or contact our official customer service staff.

[Failure] Common Faults and Treatment Methods of UVLED Curing Equipment
[Failure] Common Faults and Treatment Methods of UVLED Curing Equipment
The UVLED curing device has been used in many industries. Here we use the device of Zhuhai Zhuhai Tianhua Electronic Co., as an example to analyze the most common faults and solutions of these devices in daily life. 1. Put the alarm. In order to ensure that the work is normal, the UVLED curing equipment will detect the sensor inside the light source when booting. If it is not detected, check whether the connected cable is well exposed. If there is no problem, replace the sensor inside the light source. Over. 2. The temperature of the light source is abnormally elevated. Due to the huge heat of the light source, the two ways of heat dissipation and water cooling with fans and water cooling are generally used. If it is a fan cooling, check whether each fan is operating normally. You need to check whether the sink inside the light source is blocked. 3. The irradiation effect is not satisfactory. First, use the inspection distance whether the irradiation distance is normal, whether the various UVLED lights of the light source can light up, and whether there is an abnormal phenomenon of light emitting. Of course, some faults, such as unable to drive the machine, the touch screen does not respond, etc. These require the manufacturer's professional and technical personnel to solve.
