- Q:22 what is the power of the led lamp charging desk lamp v
- Desk lamp is generally have a transformer, the home into a 12 v voltage of 220 v.I hope you can help me
- Q:LED lamp, 220 power supply what do you mean?
- Household power 220 v.Can be directly use mains 220 v power supply.
- Q:I'm doing a LED desk lamp, can be through the outside light intensity automatically adjust the brightness of LED, using PWM technology, how to do excuse me
- With photosensitive components after sampling the operational amplifier amplification, then send the feedback signal input terminal of the PWM controller, light to adjust the sensitivity of the feedback signal strength by adjusting the op-amp magnification (resistance), no need for A/D converter and SCM, that is too complex, workload big cost is high. A photosensitive diode, an op-amp, a PWM controller (e.g., UC3843), plus a few resistance capacitance inductance, there are ten yuan or so.
- Q:A led desk lamp always zi zi ring is how to return a responsibility?
- Poor contact After a long time aging.Poor contact After a long time aging
- Q:How many good study led desk lamp
- What do you mean how many degrees? Power? Brightness? Intensity of illumination? The temperature?With 3-5 w power leds.
- Q:Charging indicator has been on desk lamp, led lamp is not bright after rotary switch
- The lamp plug is bright, have nothing to do with the back. Led not bright need to make sure this a few places, is there any battery, led to have bad, switch to have bad, line if there is any break in the middle. Best use multimeter measure.
- Q:Whether the LED desk lamp, luminous points: two guide plate and the patch?
- Yes, with the guide plate is commonly known as the "light", luminous uniformity is better than patch directly on the shiny surface, but the cost is much higher.
- Q:The maintenance of the charging table lamp
- Household appliances maintenance led rechargeable lamps? Many users haven't noticed that some users will be LED rechargeable lamp is like electricity used up until then recharging it when you are going to use it. LED rechargeable lamp light life is compared commonly, if it is not because the excess voltage or short circuit, usually don't burn out.
- Q:When did you buy? If it is just bought, suggest you use first photoelectric charge again
- LED, LED because of the different luminous principle, eliminate the stroboscopic and has high photosynthetic efficiency and pursue higher photosynthetic efficiency potential Advantage is small volume, no stroboscopic, including UV, high light efficiency, using high quality chip (OSRAM, day, and the name of the CREE) products can reach more than 80 or 80 color and has a long life The disadvantage is that the current national standard uncertainty, the products on the market anomalies chaos, most manufacturers use inferior chip led to less than 50 color... And LED chip due to poor use drive electric power are different, such as chip array and flashing brightness difference problem In a word, If conservative and don't care under the condition of light, it is best to use halogen light source to read; Care about energy saving problem use energy-efficient light bulbs, but must pay attention to choose big, because of the small manufacturer use halogen powder phosphor color rendering index less than 70, the same is not suitable for reading; If the pursuit of high-end, strict energy-saving, wish longevity noodles and the modelling of traditional light source, can choose LED products, but the best choice in the lighting industry's top brands and formal channel, so as to the quality of the products
- Q:Need to solve the problem of the LED light flashing
- Problem in the connection on the way, I guess you're mistaking 40 simple lamp bead is divided into 10 road, every 4 star all the way, so directly in parallel on the 12 v is? First answer me how do you connect again to teach you.
