- Q:High-power LED the lamp that shield an eye more appropriate
- 1 year than energy-saving lamps use 80 KWH, take 40 yuan, really want to save money a lot. And national electricity resource gap is big, also do not encourage you to use white definite lamps. 6 w LED is very bright, but a little bit far distance of illuminance are not idle, half reading needs illuminance in 300-500 lx, far from textbooks some big power, small power from the textbook, with your eyes feel comfortable as well.
- Q:Led lithium battery lamp, rated input current 0.5 a
- Charging current is a bit big, easy to cause the battery heating, out in the end. Or the cause of desk lamp current charging circuit for burning.
- Q:Desk lamp good still tube of good to buy LED strips?
- Good light source directivity, on-demand lighting, as an emergency lamp is better. 2, small volume, the LED is basically a small chip is encapsulated in epoxy resin, and so it is very small, very light. 3, intensity of illumination is enough, meet the demand of your general illumination.
- Q:The LED current problem? LED lamp current problem?
- USB interface receive computer desk lamp, computer burden is heavy, easy to addled computer. Besides, desk lamp, desk lamp, 1 a current lamp current 190 ma, bad, or move a few desk lamp table lamp lights die.
- Q:Light flashing, if is to use the adapter, it is possible that the adapter, try out in later.
- This seems not, but can be modified, specific how to operate, can go to the shenzhen LED lighting look at technical articles on net
- Q:Led lamp, good point light source or surface light source
- Desk lamp to see is to choose lamp holder types use the bedroom or in the study, the study USES led is very good choice, monochromatic light color cold light source, can help clear your mind to learn reading; But the bedroom use or suggest using incandescent lamp, mild color, adjust the mood to sleep. Get to the point, it is recommended to use surface light source, light area is larger, help reading and prevention of myopia.
- Q:I am doing an LED desk lamp,
- A photosensitive diode, followed by current - voltage conversion and amplifying circuit, and then sent to the AD converter, into a digital signal, for single chip microcomputer. Single-chip microcomputer according to the amplitude to send a PWM control signal to the pulse width control chip.
- Q:The lamp that shield an eye is after the light lamp or led the good
- LED you to choose natural white warm white (neutral) is not dazzling
- Q:LED lamp is broken, put it down, things do
- Using the multimeter, diode first gear test lamp bead is damaged. Then find a chip, CL BP OB or PI, NXP driver chip both at home and abroad, and design a constant current drive power supply. Of course also need to look at your desk lamp lights, string and how. General desk lamp is the output of 0.3-0.35 - A, your driver can be designed so that the output current.
- Q:Led and energy-saving light which good? To solve the
- 3, energy-saving lamp power consumption is too large. White LED power consumption is only 1/10 of incandescent lamp, energy-saving lamp of a quarter. 4, energy-saving lamps, easy damage, short service life. Led lights, longevity life can reach more than 100000 hours, can work at high speed. Energy-saving lamps if frequent start or shut off the filament broken will be dark soon. 5, a single LED low power, and energy-saving lamps to achieve the same brightness require multiple parallel. 6, the led light color rendering index is low, under the led light display color no real energy-saving lamps
