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 voltage of the LED lamp is about how much
No, now the best solution is a string of ten. And then in parallel. Voltage is controlled in 32 v, with constant current source driver. Safety, high efficiency
Q:The LED lamp can use while charging?
Quality is better, is to use the constant current source, you can charge while using, quality generally USES is voltage source, charging or not of the lamp voltage constant, can also charge while using. Quality again almost lamps and lanterns, the battery light directly, when charging, with charging part of the road, as long as the battery line voltage is also the normal range, flushed the edge can be used. The worst may be something wrong with the battery, charging circuit directly to the led lamp, so it is easy to burn out the light, it is recommended to use multi-function controller, can control the charging and discharging, ensure the safety of the leds.
Q:Three lights in parallel, and should be how the resistance of the step-down series?
If you are sure with 6 v battery power supply, then I suggest you use four leds, two series and then parallel, such high efficiency
Q:Led rechargeable lamps how to charge
Try every half hour after 2 hours filling light observation (do not charge while light), plus fruit no longer increases should be full of light is the brightest and desk lamp brightness, floating charge time same again can
Q:LED dual-mode folding desk lamp on external what meaning be
LED desk lamp, driving power and desk lamp is divided in two, the vast majority of dc lamp, socket is a circle with a small stick of that kind of, need with the corresponding hollow plug connected to a dc power supply. When you need to use, will drive the dc output of the power plug into the desk lamp of light, and then open the power switch, the lamp light, bright, that's the beauty of dc lamp, this is the external power supply.
Q:Light flashing, if is to use the adapter, it is possible that the adapter, try out in later.
Because incandescent lamp and electronic energy-saving lamps in People's Daily use still occupies a very high proportion, in order to reduce the waste, LED lighting manufacturers must develop in accordance with the existing interface and habits of the people are using the LED lighting products, make people don't need to replace the original traditional lamps and lanterns pedestal and lines can be used under the condition of a new generation of LED lighting products. So the LED ball steep light was born. LED ball steep light used the existing way of interface, the screw (E26 / E27 / E14, etc.), pin (B22, etc.), and even to accord with the habits of people to imitate the appearance of the incandescent light bulb. Based on LED light-emitting principle of unipolarity, designers did change in the lamps and lanterns of the structure make the LED ball steep light light distribution curve of the basic point source of convergence with incandescent bulbs.
Q:LED rechargeable lamp, can you tell me how long does it take to charge for the first time?
Don't believe the LED, he is still a myth, LED light source is the most hurt eyes. Do you see what do the lamp act the role ofing use LED desk lamp.
Q:Why my desk lamp light will keep the cell phone camera shows and white flashing light and shade stripes
This is because, you are the light source is not continuous, it is actually in the rapid flashing, just flicker frequency too quickly, the human eye cannot perceive, so feeling is always in the light. Mobile phones, unlike the human eye, sensors are refresh regularly, when the refresh rate and light stroboscopic rate when there is a mathematical relationship, you will see the stripes, when the refresh rate and blink rate just appear a integer times, stripe can rest on the screen. This and use digital camera CRT screen will appear flashing is the same.
Q:There are several major disadvantages of LED lamps
LED lamps and lanterns is due to the low entry barriers, including some of the unqualified products, domestic also lack the quality of detection means, mainly in the developed countries of quality inspection standard.
