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:How to choose the bulb power?
If it is household, choose the separation side, because the separation type is relatively safe, easier to pass through safety regulations, but the cost is relatively high, but suitable for home use.
Q:Will the power of the LED bulb grow longer and longer? Why?
The LED bulb does not become more powerful for extended periods of time.As LED chip light emitting device of the PN junction has a negative temperature characteristic: with the increase of temperature, the conducting voltage drop caused current rise, therefore, when the LED bulb is lighted with the temperature rise of power consumption will be increased. But good circuit and parameter design can reduce the influence of this temperature.
Q:Why can't the voice switch control the time of the LED bulb?
Originally white silk lamp, later replaced by LED bulb, with a light activated switch control, replaced by LED bulb, the lamp does not extinguish for 30 seconds
Q:What does the LED bulb patch mean?
The LED patch (SMD) is made of FPC circuit board, LED lamp and high quality silica gel sleeve. Waterproof performance, using low voltage DC power supply is safe and convenient, light colors, bright colors; outdoor use can be anti UV aging, yellowing, high temperature resistance and other advantages, the products are widely used in building lights, decorative lighting, advertising and entertainment quasi decorative lighting lighting field.
Q:Seeking the production process of LED bulb... Thanks
10 points, Baidu wants to be a LED engineer. LZ is a real budget man
Q:Can the bulb's true life reach 30000~50000 by LED?
The theory of the life of LED is one hundred thousand hours, this is not true; but the LED life is far less than one hundred thousand hours, only ten thousand hours, which is currently the most industrialized production of long life; because the quality of the LED part of the core - epitaxial wafer has not reached the ideal state, there are many problems to be solved, such as reducing the dislocation the density of epitaxial film, high quality P GaN preparation etc.
Q:Ordinary lamp LED bulb can?
It should be clear, your point is before the lamp lights inside what, from the rectifier? LED bulb is mostly with drive, if there is no self rectifier lamp light, the best is the bulb is directly connected to the E27/E14/B22 lamp, LED lamp or light source has a good energy saving effect, mercury free lead-free, no stroboscopic, energy than traditional fluorescent lamp 80%
Q:LED what are the bulb screws?
Ordinary bulb is the most common, is a metal electrode which is threaded, so it requires that one electrode when installing the socket contact thread to pick the zero line, the middle dot electrode lamp power. Otherwise, an electric shock occurs when an accidental contact with the exposed metal. Because of this symmetrical way, the bulb can be threaded to fit the socket.
Q:LED what does "A60" mean by bulb 60? And what does "MR16" mean?
60: diameter 60mm (metric unit) MR16: diameter is 16*1/8*25.4mm (Imperial units), although refers to the diameter, but the height and other dimensions are also prescribed
