- Q: LED bulb PC, will the white cover affect the color temperature of the finished lamp?
- In the integration sphere measurement, there is no standard lamp to proofread, or something else in the interior affects the measurement result, for example, the color of the lamp body itself will affect the color temperature more or less. Single color beads, chip on the aluminum base?
- Q: LED bulb with what type of LED beads?
- Of course, the more high-end heat better use EMC3030 lamp, EMC2835 lamp and so on, please consult your supplier
- 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: 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: 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: What's the reason for the LED bulb strobe?
- 8W offline LED driver GreenPoint reference design with solid state lighting standard energy star "as an example, the sine wave regulator side flyback power conversion does not provide constant energy to the primary bias, dynamic self supply (DSS) circuit can be activated and the light induced flicker. To avoid this problem, it is necessary to allow primary bias to be discharged at each half cycle, and accordingly, the values of the capacitance and resistance that constitute the bias circuit need to be appropriately chosen.
- Q: I want to ask for high power LED bulb lamp wire inexplicably broke, and in large quantities. Is the quality of the lamp?
- A sense of self is the following 1. package production process of wire bonding or partial welding weld. Whether the station is too large.2. through the current impact blanking line3. package factory using gold thread may be too fine
- Q: How to identify Ic constant current LED bulb?
- Let me tell you what. If the bulb is not damaged, the regulator needs a regulator to lower its voltage and see if the bulb's brightness is dark. If it follows, it is not a constant current source, but a blocking capacitor. If the voltage is greatly reduced, the brightness change is not constant, that is, the constant current source bulb (because the constant current source lamp can change between 80V--260V, the voltage is normal, and the output is constant).
- Q: What advantages does LED bulb replace energy saving lamp?
- The LED lamp is solid-state lighting, if all LED lamps a year remaining nearly three electric power Three Gorges hydropower station, the country.
- Q: What does "A19" mean in LED A19 bulb?
- A stands for bubble type, A hemisphere bubble19 the numbers in the back indicate the size of the bulb (mm in diameter)On the market LED bulb generally has: hemisphere bubble lamp, A15, A17, A50, A60Global bubble G45, G55, G80, G120 and so on
