Many people often ask, we line G4 LED, GU5.3 LED, G9 LED is what it means, in fact, G4, GU5.3, G9, respectively, they represent the lamp (lamp beads) pin type. The way the bulb is linked is inserted, we denote G, where the Arabic numerals represent the distance between the center points of the pins (where 4,5.3,9 represents the distance between the two pins is 4 mm, 5.3 mm, 9 mm).
High voltage GU5.3 LED input voltage High voltage GU5.3 input power for the narrow voltage input, usually 110v and 220v can be used normally. But does not support dimming.
Low voltage G4 LED, GU5.3 LED and switching power supply. First, the switching power supply is DC, suitable for such as digital products, computer chassis, massage, electronic scales lamps, LED lamps, security monitoring. 12V switching power supply common output current: 500mA, 2A, 5A, 30A and so on. If you need more light beads at the same time work, you first use the power of the switching power supply divided by the actual power of the lamp, and then multiplied by 0.8, the integer part is the number of lights can be loaded, and parallel access circuit.
Low voltage G4 LED, GU5.3 LED and LED driver. We call the AC current constant current output, when we choose to use AC drive LED, the output current must be, the output voltage is not fixed. We use 12V power supply to the low voltage G4 power supply is because 3 * 1WLED drive output voltage is close to 12V. Constant voltage G4 can not use LED driver as the driving power, otherwise there will be too bright, light failure, and even dead light situation. Constant current G4 and low voltage GU5.3 because it has a constant current power supply board protection, it can be compatible with the LED driver. One 3 * 1W LED driver can only take a constant current G4 or low voltage G5.3.
G4 LED drive program there are many, here is about constant voltage G4 and constant current G4 these two. Constant voltage G4 drive voltage is DC12V. Constant current G4 drive voltage AC12V, while DC12V can also drive constant current G4 normal work, so we can see in many shop business G4 LED ACDC 12V words.
High pressure products use Note ① lamp body heat is a normal heat dissipation; ② all products used indoors, can not be stored in the wet environment, use; ③ products in use, it is strictly prohibited to touch the lamp body part; ④ not too frequent plug Pull the product; ⑤ in the plug the product, the need to operate in the case of power; ⑥ according to the local electricity situation, select the appropriate input voltage products.
