Q:Will the power of the LED bulb grow longer and longer? Why?
Voltage problems, as well as unstable factors.Long time no change, should
Q:How to choose the bulb power?
Obviously, the designer doesn't want the ball lights to work at rated current, but there is a margin, so the light bulb will work more reliably. Because of the constant current source, current of each lamp is not 30mA, but 330mA/13=25mA, of course, the brightness of the lights will be smaller.
Q:How does the LED bulb look good or bad?
See brightness, whether the luminous uniformity, the back of the heat is good?
Q:LED how does the bulb return electricity?
maybe because Make the question clearWhat is the return current?
Q:What advantages does LED bulb replace energy saving lamp?
The response time is fast, the energy saving lamp is millisecond, and the LED light is nanosecond
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
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:The difference between an incandescent lamp, an energy-saving lamp, and an energy-saving LED bulb
The light produced by the three is different. From the lighting point of view, incandescent light can generally emit yellow light, and energy-saving lamps can not only send yellow light, but also white light, etc., and LED lights can be issued according to the needs of a variety of light, decorative lighting is very good.
Q:Why is 3W's LED plastic bulb so cheap on the market? Is there any drawback to the price difference between aluminum and aluminum?
Now the market LED lamps quality uneven. LED lamps need constant current and constant voltage drive to be durable. The cheap 3W LED plastic bulb power supply is only the drive of the resistance capacitance pressure drop. Drive rank: 1. constant current and constant voltage drive. 2. constant current non constant voltage drive. 3. constant pressure and no current drive. 4. resistance capacitance pressure drop drive (resistance capacitance voltage drop is the worst and cost is the cheapest)
Q:LED what is the plastic shell of the bulb? What plastic material is better? What do you need to pay attention to?
There are several good LED ball bubble, which with aluminum cooling. Relatively new appearance.
