1.Q:What's your payment terms?
A: T/T or L/C
2.Q:When could you send me the samples
A:2-3days
3.Q:How long is the bulk time?
A: About 8-25days
4.Q:Do you also sell other kinds led lights?
A:Yes, we also supply led bulbs, spotlights, led light, led tube light ,ceiling light etc.
- Q: The led rechargeable lamps useless can also be used for a long time
- I am LED lamps and lanterns is developed. LED lights actually there is no essential difference with traditional use of lamps and lanterns.
- Q: Led the desk lamp that shield an eye how to choose?
- Eye protection is our life lessons, eye to start at a young age. Students in rapid growth stage, the body should protect the pair of the window to the soul. Eye can reflect on a lot of details, the lamp that shield an eye can greatly alleviate eye fatigue, protect your eyes from harm. The lamp that shield an eye is not adjust light brightness, who can adjust the brightness of the lamp that shield an eye eye function. Is the price is more expensive than ordinary ordinary incandescent bulbs. The lamp that shield an eye lamp luminous color temperature value determines the degree of light is downy, high and low are not good, is suitable for 4000 k to 5200 k. The lamp that shield an eye of 4000 k to 4500 k, the light is slightly red, more soft, suitable for primary school students; And 4500 k to 5200 k color temperature value is suitable for middle school students and its older customers to use. There is good, had better choose light yellow lights for under the yellow light will feel soft and comfortable to read and write, by reading in white, for a long time will feel sore eyes. The choice of the desk lamp that shield an eye still depends on the brand, good brand of the lamp that shield an eye quality guaranteed, the quality is qualified through inspection
- Q: The LED rechargeable lamps can charge while lighting? The reason?
- Can't, or it will burn out all on your desk lamp led diode, the reason is that the charger is not isolation transformer, but electronic charger, electronic charger with high pressure when charging, if turn on the light use, breakdown, all leds, so can't charge while lighting
- 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: What kind of USB power adapter for a LED light source is a USB power supply lamp?
- On the market to buy the USB power supply, the output voltage 5 v dc, can plug in the USB lamp, power supply directly.
- Q: The principle of LED the desk lamp that shield an eye
- Such competitive incentive LED manufacturers to further expand their product type, and actively seek the LED application field has obvious competitive advantage. After that the LED has applied to text dot matrix display, background light grid and the map array. Digital display the size and complexity of the growing, from 2 digits to three or even four, from section 7 of figures to display complex words and design combination of 14 or 16 segment array. To provide intelligent lattice LED display manufacturers started in 1980. The advances in technology have made the LED can be used in outdoor sports information release and car central high stop lights (CHMSL) equipment installation. Highlight blue LED to the invention of the realization of image advertising display screen, the screen can display image, full-motion video image. The emergence of blue leds can make people use backward transformation of phosphorescent materials from high-energy blu-ray partially converted into other colors. Now only use LED light source can be completely cover all saturated color of CIE chromaticity curve, and all sorts of color of LED and the organic integration of phosphorus can almost any color without any restrictions. In terms of reliability, the half-life of the LED (that is, the light output was reduced to half the time of the initial value) is about 10000 to 10000 hours. Instead, small type indicating the half-life of incandescent lamp (half the half-life of here refers to the number of lamp failure time) typical values is 100000 to thousands of hours, depending on the light of the rated current.
- Q: The problem with LED charging lamps?
- You look at the instructions, if 10 hours are used up, then the general new will be more than 10 hours. The big brands generally describe relatively conservative performance objective.
- Q: Desk lamp battery charging why not directly connected light emitting leds, but to a diode, the diode have what effect
- See what the battery, the normal pressure drop of white LED is controlled in 2.8 3.6 V, if use lithium battery 3.7 V voltage is a little high, if he does not limit current will be very big, LED immediately to turn the raw materials.
- Q: The service life of LED lamps and lanterns is true?
- General lamp life 50000 hours, mainly depends on the service life of the power drive, the design of the ordinary not so long, but no electrolytic solution can be in fashion now.
- Q: Desk lamp good still tube of good to buy LED strips? Search light tube usually can use a few years need to change?
- 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.
