- Q: Where can LED bulb be used?
- The surface of the lamp body is sprayed with high quality heat radiation paint, that is, the heat dissipation efficiency is ensured, and the appearance is elegant, and the utility model provides better guarantee for the low temperature work of the product.
- Q: LED bulb lamp drive power electrical connection, will delay a few seconds before the lamp light, and power creaks, who know what it is!
- Delays generally do not exceed 1S. After rectification, the capacitor is charged to the IC VCC terminal through the starting resistance. When the starting voltage of the IC is reached, the output switch pulse signal of IC is LED, and the luminous work is realized.. That is to say, the greater the capacitance, the longer the delay.
- Q: Seeking the production process of LED bulb... Thanks
- First of all, of course, the preparation of materials, the specific operation of the lamp to practice, each lamp has different methods of assembly, there are different work instructions. Only through practice can we write good and practical processes. Figure is a flow chart of MR16 assembly.
- Q: What are the types of LED bulb?
- The LED bulb replacement use convenient, makes this type of products are widely accepted by users by the family, under the same illumination conditions choice to replace the traditional lighting.
- Q: What's the reason for the LED bulb strobe?
- In addition, electromagnetic interference (EMI) filters are also required, even in LED drive applications that provide excellent power factor correction and support TRIAC dimming. The transient current caused by the TRIAC step (step) will excite the natural resonance of the inductance and capacitance in the EMI filter.
- Q: I want to ask for high power LED bulb lamp wire inexplicably broke, and in large quantities. Is the quality of the lamp?
- Or if there's a problem with the process, just zoom in and see!
- Q: How to identify Ic constant current LED bulb?
- Look at the power supply, there are a few simple electronic and capacitive circuit board, it is not constant flow, cross flow is larger, so understand? Cross flow IC, that is, the meaning of intelligent voltage regulator, so that the LED is not easy, bad capacitor driven LED is relatively easy to damage, easily breakdown, and power consumption than the cross flow
- Q: Are there any differences between negative ion bulb and LED bulb?
- The brightness of LED anion bulb of each LED have good consistency, high color purity, light stability. 1W power, ultra low energy consumption. A variety of light colors are available for you to create a dream like color space. Built in negative ion generator, each cubic centimeter produces 3000000 negative ions that allow you to have a healthy air environment while you own light. Negative ions can effectively remove formaldehyde, benzene, toluene, ammonia, acetone, carbon monoxide, sulfur dioxide and other toxic gases, for your breathing health increased by a solid line of defense.
- Q: LED bulb after the power failure, still glimmer, can last hours or even all day, what is the reason?!
- If it is to continue the glimmer of minutes, the main side is the use of resistance and step-down circuit caused by the normal phenomenon. It's very rare for the factory to use this old model to make LED balls. Circuits that run for hours or all day on the side of the LED bubble are out of order. It's not normal to shine for so long. Now most of the LED bulb is using IC constant current supply circuit, no such situation has emerged.
- Q: What does "A19" mean in LED A19 bulb?
- A19 is the European A60: represents the outer diameter 60mm=19/8*25.4=60.325mm, such as the diameter of the A19 bulb. "D=19*1/8", multiplied by 25.4, is the diameter of the bulb in mm units. The source of this formula is the same as the T8 tube: "X" in Tx means that the diameter of the tube is x times 1/8 inches, so the diameter of T8 is 1/8 inches x 8=1 inches, or 25.4mm
