Q:Why can't the voice switch control the time of the LED bulb?: The production lights can be controlled. Where do they go to consult?

Q:LED can the bulb be used in the bathroom?: Kitchen lighting bathroom and kitchen with special waterproof, but the working voltage of LED is low, LED lamp is also a big problem in the use of a water vapor environment, general heat sink should be no problem, is such as the use of aluminum shell, like plastic shell can not, because they on the cold and hot air convection cooling, casing is provided with a hole for air inside and outside the exchange, will put into the high-pressure part of water vapor driven, it will affect the service life.

Q:What's the reason for the LED bulb strobe?: Common causes and treatment of LED light flashing:Generally, the human eye can detect light flashes with frequencies up to 70 Hz, which are not sensed above this frequency. Therefore, in LED lighting applications, if the pulse frequency appears below 70 Hz low-frequency components, the human eye will feel flashing. Of course, in specific applications, there are a variety of factors that may cause LED lights to flicker. For example, in offline low power LED lighting applications, a common power topology is an isolated flyback topology.

Q:What is the AC voltage of the LED bulb?: The conventional way to make multiple voltages is the 90V-240V ~50/60HZ 12V

Q:What brand of LED bulb is good in quality?: The price of these lamps is very low, but the quality is not guaranteed at all. The purpose of this article is to teach consumers to distinguish the quality of LED bulbs on the market so as not to be cheated. So, which brand LED bulb is good, choose a good brand, first of all should first understand how the quality of its products

Q:Are there any differences between negative ion bulb and LED bulb?: LED bulbs are made by plug-in lights or SMD or high-power LED, and there is no built-in negative ion generator.

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!: How many seconds delay? It won't take so long. How many bulbs do you usually soak in 0.5 seconds? A squeaky noise is usually a transformer or inductance whistle, and at least it shows a poor manufacturing process.

Q:Will the LED bulb, T8, T5 lights, radiator lamps, is the hotter the better? What's the regular temperature? What are the common heat release materials? Specifications?: Of course, the hotter the better, because for the same material, the hotter it is, the more heat the LED chips use, the less good the quality of the chips. The thermal characteristics of lamps is mainly to measure the junction temperature of LED Shenglai rather than the temperature of heat sink. Aluminum is commonly used in heat dissipation materials.

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 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
