- Q: Charging indicator has been on desk lamp, led lamp is not bright after rotary switch
- Hello, if you have a multimeter, please measure the lower limit of flow resistance, the lamp easy to burn current-limiting resistor, especially when charging turn on the light. Visual blue that resistance to fire.
- 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 the desk lamp, electronic calendar watch how to adjust?
- In normal state, the LCD screen display ALARM logo above the "ALARM", according to "bring" button to open/close to sleep function, the LCD screen above "SNZ" logo will display and not accordingly. In normal state, press "▼" button to open/close function of music appreciation. When open circuit play 7 different music. In normal state, press "SET" key Celsius/Fahrenheit temperature conversion can be realized. In the above calendar clock operation, 1 minute, if no buttons are automatically return to normal state
- Q: Led desk lamp and common desk lamp which is good
- The launch of the white light LED light source can form mainly consisted of 450 ~ 455 nm wavelength of the blue light stimulate phosphor powder, including lower wavelength firing ability are more strong. Usually LED lights factory within a 500 - nm wavelength control, generally is 450 ~ 455 nm or 455 ~ 460 nm, belong to the strongest radiation damage extents
- Q: LED the desk lamp that shield an eye to choose good warm light or white light is good?
- Should choose the warm light, soft and not dazzling.Which is better than the sun warm light
- Q: I had had a 20 leds rechargeable lamp, then search the battery is broken, I version removed yourself to make the lamp, can directly use electrical appliances, please start
- Home appliance is 220 v ac? That obviously doesn't work, even if 20 LED series also not line, you can get a suitable small transformer, low output voltage is used.
- Q: LED the desk lamp that shield an eye the choose and buy, should consider what respect?
- Optical processing, due to the LED lamps are using LED chips as light source, belong to the point light source, so the reasonable optical processing technology is very necessary.
- 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: Led lamp generally not transformer, why also said some led desk lamp radiation levels
- Some led lights use switch power supply So the excess radiation
- Q: Hurry, common desk lamp is ac or dc output, and energy saving LED lamp?
- The output ac socket After the transformer voltage between 8 v 10 v 20 v ranging from energy-saving led equivalent
