- Q:Detailed description of LED bulb lamp
- High purity aluminum reflector, radiator, acrylic glass cover, high power LED light source, high efficiency imported constant current source. 2. The bulb has high luminous efficiency and good environmental protection performance. It does not contain harmful substances, has no pollution to the environment, does not have infrared rays and ultraviolet rays, and avoids harm to the human body, and belongs to the green lighting products. 3, PC light shield, optional transparent or matte, to prevent glare and effectively protect the LED lamp, unique optical design, light distribution. 4, good color, to show a true color of things, a variety of color options, to meet the different needs of the environment, eliminating the traditional lamp color temperature depression caused by excessively high or low, the Department of visual comfort, improve the working efficiency of workers. 5, the bulb of the spiral points E27 and E40, easy installation, alternative to the traditional 65W125W energy-saving lamps. 6, the bulb is made of high quality aluminum alloy for shell production, good corrosion resistance, long service life, energy-saving effect is obvious. 7, bulb 30W installation height of 3-4 meters, 50W installation height of 5-6 meters.
- Q:How did the trademark on the LED bulb go up?
- And the use of silk screen or pad printing, this is the need for the corresponding ink, this solution with a dedicated solution can be dissolved, and also have some prominent hand touch.
- Q:Want to find common features, unified purchase accessories repair!
- The proposed open, lamp is broken, can find light black or other unusual circumstances, bad power supply at the circuit board and components have the same burn what, under normal circumstances is such.
- Q:What's the reason for the LED bulb strobe?
- If this resonant characteristic causes the input current to fall below the TRIAC sustaining current, the TRIAC will turn off. After a short delay, the TRIAC usually switches on and fires the same resonance. In the 1.5 cycle of the input power waveform, this series of events may be repeated several times to form visible LED flashes. To cope with this problem, a key requirement of TRIAC dimming is that the input capacitance of the EMI filter is very low and that the capacitor is decoupled through the TRIAC and the winding impedance. According to the formula, if the capacitance of the dimming module is reduced, the resistance of the resonant circuit can be increased, and the oscillation is suppressed in principle, and the desired circuit work is resumed.
- Q:How to choose the bulb power?
- If the public is not high, the quality requirements, and to control the price, you can choose non isolated, because it does not require isolation transformer, so the cost is relatively low, but the aluminum substrate voltage requirements is relatively high, otherwise there may be charged radiator, and still light outside is not very beautiful.
- 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.
- Q:Can the bulb's true life reach 30000~50000 by LED?
- The white LED lighting bulb basically is to use GaN based blue LED excitation light yellow fluorescent powder to realize white light, which is a two yuan color white, there are three kinds of RGB LED chip mixed light, but the high cost of LED, the general industrial production less
- 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 is the 15 Watt lumen of the LED bulb?
- LM, refers to a candle (CD, Candela Candela, unit of luminous intensity, the equivalent of an ordinary candle light intensity) in a solid angle corresponding to the spherical cone ball (1 square meters of the unit sphere radius of 1 meters on the representative point of view, the corresponding section in the center angle of about 65 degrees the total emission flux) on the.
- 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.
