- Q:LED what kinds of screw bulbs are there?
- LED bulb lights are E14, E27, E40, B22. The most common family is E27, also known as big headed screw. There are also some lamps, E14, called small headed screw. These two are the most common energy-saving light interface. Before there are B22, that is, the kind of card, also known as bayonet. It may be common in the countryside, but now it has been phased out. There are some industrial use of more E40, more than 80W energy saving lamps will be used, that is, the interface is relatively thick.
- 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 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:Is it possible to manually weld LED bulb bulbs?
- If you can guarantee that you can add thermal grease just fill the gap without obstructing the normal contact, it is useful, but this process is very difficult for you to do, and the theory can improve the thermal efficiency of thermal grease, but actually you are not up to the process it is possible to reduce the thermal efficiency, you added more is to seek psychological comfort, you can on the heating plate welding of light, with one side of the thermal grease solder, such thermal effect is better
- Q:What material is applied to the glass cover of the LED bulb? Can reach 90% of the light, can not see the inside of the lamp. Who knows, thanks for telling!
- Can reach 90% of the light, can not see the inside of the lamp
- Q:Detailed description of LED bulb lamp
- A bulb can be said to be the highest cost of the driver, not the driver, light is not bright. And for the quality of a ball bubble
- Q:What are the types of LED bulb?
- According to the radiator shell to points, can be divided into plastic shell, aluminum radiator and ceramic shell, in general, the ceramic shell heat radiator is best, but the price is relatively expensive, the widespread use of aluminum shell, moderate price, good heat dissipation performance
- Q:How to identify Ic constant current LED bulb?
- Hello, LED market is now very confused, this problem is the use of LED lamps of the users are more concerned about the problem, the so-called IC constant current drive power refers to the LED lamp (commonly known as the transformer) with a constant stream of multifunctional IC chip, the IC is generally 5-8 feet (depending on the model and decision scheme), role is to ensure that the current through LED lamp is controlled in a relatively constant parameter, ensure the long-term stability of LED lamp work at constant current. When the input or output voltage is changed, the current through LED remains constant, so the constant current IC of the LED light stability and service life is directly related to the IC also includes internal short circuit protection, overtemperature protection function of open protection etc.
- Q:LED bulb after the power failure, still glimmer, can last hours or even all day, what is the reason?!
- If the switch is installed on the zero line, LED is the resistance capacitance step-down if the light shimmer is mainly the induction voltage capacitance inside (with the switch installed on the line Never mind, because there are capacitance induction voltage). The meter won't turn. Of course, you can not expect to use this induced voltage to lighting, because this voltage is extremely weak, unable to meet the minimum requirements for lighting. If the switch is on the zero line, and there is a problem with the capacitor in the capacitive circuit, it is likely to be a long time. Over time, the circuit in the LED light proved to be a problem
