Hello everyone, I am a dream. Today, let ’s introduce the problem of the measuring method of chandeliers LED lamp beads LED lamp beads. The following is a dream of summarizing this issue and related issues. Let’ s take a look. Catalog of the article: 1, how many watts of LED lamp beads 2. LED lamp bead measurement method 3. The LED lamp beads on the lamp is about how much watt. How to lighten LED little lamp beads How much tiles of LED lamp beads
LED little lamp bead is? The smallest lamp bead is generally a small lamp bead and a tile. Your LED lamp card has 15 lamp beads 15 watts, which is the most basic configuration. Generally, small lamp beads can reach 0.5 watts. 100 such lamp beads reached 50 watts. Now the LED lamp lamps of the household brand, Uncle Wishi, is all enough in one watt brightness. I hope my answer can help you.
LED lamp bead measurement method LED lamp bead detection method: 1. Red ink test: verify the qi of the LED lamp bead. 2. Cold and thermal impact test: Detect the comprehensive performance of LED lamp beads. 3. Salt Mist test: Test the corrosion resistance of LED lamp beads. 4. High -temperature thermal cycle test: Test LED lamp bead anti -aging performance.
LED English is (LightemittingDiode). LED lamp beads are the English abbreviations of the light -emitting diode, which is a popular name.
LED lamp bead characteristics: 1. Voltage: LED lamp beads use low voltage power supply, the power supply voltage is between 2-4V, which vary according to the product, so it is a safer power supply than a high-voltage power supply, especially Suitable for public places 2. current: working current is 0-15mA, and the brightness becomes brighter with the increase of the current. 3. Effectiveness: The consumption energy is 80%reduced by 80%compared with the incandescent lamp with the same light. 4. Applicability: Small, each unit LED piece is a square of 3-5mm, so it can be prepared into various shapes of devices, and it is suitable for easy-to-change environments. 5. Response time: The response time of the incandescent lamp is milliseconds, and the response time of the LED light is nanosecond. 6. Environmental pollution: no harmful metal mercury. 7. Color: Change the current can change color. The light -emitting diode is convenient to adjust the structure and band gap of the material through chemical modification methods to achieve red, yellow, green orchid orange multi -color glow. For example, a small current is a red LED. As the current increases, it can become orange, yellow, and finally green.
There are several types of LED lamp beads on the chandelier. 1: 5mm diameter size and slightly bright LED lamp beads are about 0.07W 2: 8mm diameter and shiny LED lamp beads The square LED lamp bead is called a patch LED, which is a single 0.5W LED small lamp bead. There are four holes, first look at the hole with No. 10 in the middle of the four holes or the edge. If you are on the side, you will connect the three LED positive electrodes to this hole, three LEDs, three LEDs, The negative electrode received three other holes respectively. Whether there is an external drive power supply (adapter, or a town flower) If there is a adapter, then just take the two wires of the output end of the appleeter to get on the light. If the first way to connect the light is not on, then the pair of two lines can be turned on. Even the first error will not affect the LED light. If there is no external drive power supply, then you cannot directly connect the AC220V city electricity. If you want to judge the positive and negative pole, you can also take a look at the lights. There are generally+-mark the positive and negative pole. LED little lamp beads are lit Single LED lamp bead generally is about 3-3.5V. If you want to light up a LED light, you can add 3-3.2V voltage to both ends of it. The above is the answer to the measurement method and related questions about the measurement method and related issues of Tiancheng Xiaocheng Xiaocheng Xiaocheng. I hope it will be useful to you [Responsible Editor: One Dream] |
