LED FILAMENT LAMP BULB 4W B TYPE NEW DEVELOPMENT

LED FILAMENT LAMP BULB 4W B TYPE NEW DEVELOPMENT

Q:Why can't the voice switch control the time of the LED bulb?
Current problem. The current is too weak. You don't have to use an electric meter to see if you can work properly without a light bulb. Change the timer switch.
Q:Secret LED bulb bubble price difference why so big?
Power Supply。 Good quality will be equipped with power supply, usually in the lamp cavity. And low prices are put on the lamp board with several capacitive resistance to deal with
Q:LED can the bulb be used in the bathroom?
From a long-term perspective is not enough, you can choose a lamp are closed, such as ceiling lamps what, now have special indoor lamps, but you must not use ordinary lamps, because LED lights to the heat at the edge of the open slot or empty, easy water.
Q:What's the cause of the noise during the aging of LED bulb bulbs?
This should be the power problem. It's easy to make a noise because there are so many parts of the power supply.
Q:How does the LED bulb go with the power?
Generally we use the LED lights, 1W, 2W, 3W, 12W, and so on, the factory has been set in advance, directly connected to the 220 volt power supply can be, and do not need to be so complicated.
Q:Led the bulb is flashing. What's wrong with it? How do you fix it?
The driving power inside is broken. If there is basic electronic knowledge, replace the inner capacitor. Most probably the electrolytic capacitor is broken.However, the cost of the bulb products is relatively low, and the cost of the repair is greater than the cost of the change.
Q:What does the LED bulb patch mean?
Performance of LED patch lamp:1, micro power consumption: LED lamp, 2W brightness is equivalent to 40W incandescent brightness, 3.6W brightness is equivalent, 60W incandescent brightness, brightness in the middle stronger.2 、 voltage adaptation range: nominal 220V lamp.3 、 the light distribution technology expands the LED point light source to the surface light source, increases the luminous surface, eliminates the glare, enhances the visual effect and eliminates the visual fatigue;4 、 lens and lampshade integrated design. At the same time, the lens has the functions of light gathering and protection, thereby avoiding repeated waste of light and making the product more concise and beautiful;5 、 high-power LED flat cluster package and radiator and lamp holder integrated design. The LED heat dissipation requirement and the service life are fully guaranteed, and the design of the LED lamp structure and the shape are completely satisfied, and the LED lamp has the distinctive characteristics of the lamp;6, Aluminum Alloy lamp body and the overall molding process, to ensure a good cooling effect, reducing the effective use of LED in the process of decay.7 、 no strobe. The pure DC work eliminates the visual fatigue caused by the strobe of the traditional light source; and the environment is green. No lead, mercury and other polluting elements, no pollution to the environment;8, impact resistance, resistance to leilijiang, no ultraviolet (UV) and infrared (IR) radiation. No filament and glass shell, no fragmentation of traditional lamp, no harm to human body, no radiation.
Q:How to identify Ic constant current LED bulb?
The general user how to judge whether the bulb with constant current IC power supply, the general bulb is divided into three kinds, one is the RC driven RC drives are the most simple, because the cost is very low power small bulb and lamp using the scheme of small power LED bulb is often driven by RC, RC driving disadvantage is LED current with voltage fluctuation is changed, the brightness will change, so the resistance capacitance in the price is cheaper and less demanding bulb drive only, one with the IC LED driver, this there is also a constant current power supply, but the precision of constant current IC is not high, this power can only be used in the 220V voltage, the voltage fluctuation of relatively large area will affect the brightness of the LED lamp, and the stability of the power supply is relatively poor, life is better than Relatively short, easy to issue, this power supply is only a three - stage tube and two regulators circuit very...
Q:What does "A19" mean in LED A19 bulb?
I'm studying too! There's a problem for everyone to discuss
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.
