1. Use LED products to pay attention to anti-static
LED products should adopt anti-static measures during the process of processing, such as: workbench should be grounded, workers should wear anti-static clothing, with anti-static ring, and with anti-static gloves, etc., can be installed with anti-static ion fan, At the same time, it is necessary to ensure that the humidity in the production workshop is about 65%, so as to prevent the air from being too dry to generate static electricity, especially the green LED is easily damaged by static electricity. In addition, the antistatic ability of LEDs of different quality grades is also different, and the antistatic ability of LEDs with higher quality grades is stronger.
2. Use LED products should pay attention to the use of DC constant current power supply
Some manufacturers use the "resistance-resistance and step-down" method to supply power to LED products in order to reduce the cost of products, which will directly affect the life of LED products. A dedicated switching power supply (preferably a constant current source) should be used to power the LED product so that it does not affect the life of the product, although the product cost is relatively high.
3. Use LED products to pay attention to the increase in temperature will make the LED internal resistance smaller
When the ambient temperature rises, the internal resistance of the LED light source will decrease. If the power supply is stabilized, the operating current of the LED will increase. When the rated operating current is exceeded, the service life of the LED product will be affected. The LED light source is "burned out", so a constant current source should be used to ensure that the operating current of the LED is not affected by the external temperature.
4. Use LED products to pay attention to the sealing of LED products
LED products are often used outdoors, and they are also faced with waterproof and moisture-proof sealing problems. If not handled well, it will directly affect the service life of LED products. Some manufacturers who require high quality products use traditional epoxy resin "watering" methods to seal LED products. This method is cumbersome to operate and is not suitable for larger LED products (such as LED guardrail lights). It will also cause an increase in the weight of the product.
5. Use LED products to pay attention to the control technology of LED guardrail lights
At present, the most widely used control technology for LED guardrail lights is the "serial communication" method. The advantage is that each guardrail lamp has no specific "code", and each branch can be exchanged freely for production and engineering installation. However, its biggest disadvantage is that once there is a damage, it will directly affect all the guardrail lights behind it. For hundreds or even several kilometers of guardrail light projects, it is difficult to guarantee each due to external factors and the quality of the products themselves. There is no problem with a guardrail light. Therefore, a problem with a guardrail light causes some of the guardrail lights to linger.
Furniture Actuator
Furniture series are linear actuators designed specially for home application, like beds, sofa, lift chairs, massage armchair, lift recliners, etc. It has very low noise (quiet, <=48dB), strong load (max. 6,000N), and compact size (retracted length 163mm + stroke). And the whole motion system, including controller and Linear Actuator, is offered.
