How to use LED lamp beads? Paste lamp bands or stickers on the road board. If a small amount of stickers can be manually put on the device location, soldering iron welding, welding like ordinary patch devices in batches, there are positive and negative poles and color distinctions. Note what to pay attention to when buying LED lamp beads LED light is more practical and convenient to use, and it is widely used. What should I pay attention to when buying LED lamp beads? PCHOUSE takes everyone to understand. 1. Look at brightness. Generally, the brightness of LED lamp beads is different, and the price is different. Generally, the larger the brightness, the more expensive the price. The greater the brightness, the better the decorative performance. When buying, the LED lamp beads can be bright for a while to see how the brightness. 2, measure anti -static ability. LEDs with strong anti -static capabilities are long, so the price is high. Usually, the anti -static than 700V LED can be regarded as a real LED. It is not easy to burn out due to unstable voltage during use. 3, light wavelength. It depends on whether the consistency of the light wavelength of LED lamp beads meets the standards. The luminous color of LED lamp beads with the same wavelength is consistent. If the color is consistent, the price is high. Therefore See if the light wavelength is consistent. 4. Safety performance. The level of safety performance directly determines the long -term service life of LED lamp beads. The colloid of ordinary LED lamp beads is generally epoxy resin, and the market also has LED lamp beads with anti -ultraviolet and fireproof agent. The price is naturally more expensive. However, the safety performance of this LED lamp bead is generally high, especially when it is installed outdoors, you can use it with confidence. LED lamp beads have strong adaptability and application life compared to incandescent light bulbs, but in order to ensure that LED lamp beads work normally for a long time, they must pay attention to standard operations when applying. ? Welding conditions 1. Sbar welding: Welded welding, generally requires applicable to less than 25W (maximum value of 30w, welded temperature within 260 ° C. Welding time should not exceed 3 seconds. 2. Welding: Welding requires the top temperature of 260 ° C, the welding time does not exceed 5 seconds, and the welding position is at least 2 mm. (After the welding, the LED lamp bead temperature drops to the room temperature. Please do not use hard things. Or sharp things to wipe, rub, push LED lamp beads 2. Washing of parts After welding, wash according to the following steps. 1. You can use Freon TF or alcohol or other similar solvents as cleaning solvents. 2. 2. The cleaning temperature can be controlled at a maximum of 50 ° C or 3 minutes, which can be controlled by 30 ° C. The temperature is not high. 3. When selecting ultrasonic cleaning, please do not exceed 300W. Note that vinyl chloride, acetone, etc. will cause damage to the appearance of the colloid. You can wipe and soak it with ethanol, but do not exceed 3 minutes. 3, the device method 1. Pay attention to the outer configuration to avoid polar errors. 2. Do not get close to the heating element. 3. Do not install LED lamp beads when selling and deforming. 4. In the case of the device LED lamp bead, position the recommended shaft cover for positioning. LED lamp beads should not cause commotion or external forces. Four, temperature characteristics SMDLED lamp beads exposed in high temperature state do not rub the epoxy resin, may be wiped with other pointed objects, but Epoxy is very weak and easy to damage. . According to the temperature characteristics of LED lamp beads, the temperature rises 5 ° C, and the beam drops by 3%. Regardless of the winter season, LED lamp beads must pay attention to the work temperature and storage temperature during the summer quarter. The minimum working temperature of LAMPS is? 25 ° C maximum 85 ° C, and the minimum storage temperature is? 40 ° C maximum is 100 ° C. 2. The minimum operating temperature of the Displade of the Light beads is? 20 ° C maximum 70 ° C. The minimum storage temperature is? 20 ° C is up to 85 ° C. 3. The minimum operating temperature of outdoor LED lamp beads -20 ° C is maximum of 60 ° C, and the minimum storage temperature is -20 ° C maximum of 70 ° C. 5. voltage voltage Current 1. Not recommended LED lamp beads. This is because as long as a uniform flow circuit cannot be formed, the same product outputs LED lamp beads at the same time. In the case of lamp beads, the anti -static device is needed, and the ultra -high brightness white light LED lamp beads are damaged by static electricity. At this time, even if the naked eye is not visible, the application life will be reduced. The working current may change about 20mA. Usually, even if you use the inline limit resistance, you can also use the simple constant voltage circuit to achieve the ability to limit the pressure to avoid losing LED lamp beads. 4. Generally speaking, the peak current current of LED lamp beads For 50 ~ 100mA, the reverse voltage is about 6V, LED lamp beads are applicable Pay attention to the peak voltage and current of the planned circuit than to exceed the limit. (Especially the high output outside) The peak voltage of the circuit is too high, it is likely to damage LED lamp beads. |
