- Q: LED lamp, 220 power supply what do you mean?
- This is a desk lamp with charging function, can be directly use 220 v power supply, electric, can also charge the batteries. Tomlinson fly Lipton, op, wood, leishi, the first two high-end price is high, high performance/price ratio, and the latter two. The dense LED lighting (tao shop:)
- Q: sk next incandescent lamp, led lamps and halogen lamps have what distinction, which better
- The LED desk lamp is not, is not good for you and your children, so, cannot use LED lamp; Incandescent bulbs, as a result of energy saving, the country has banned the use of incandescent lamp, although there are on the market at present sell incandescent bulbs, but also a few businessmen in order to reduce the loss and discounted in clearance, also not suitable for you use;
- Q: How to distinguish whether the led lamps and lanterns glare, is there a standard?
- Glare can be divided into disability glare and arrow glare. Who reduce eye glare called a disability glare, it will be Reduce the visibility of the visual object, but not necessarily produce uncomfortable feelings; Who make the person produces the feeling of displeasure glare is called no Comfortable and glare. Cause glare of led lamps and lanterns has the following four major factors. (1) the light source brightness factor: the higher brightness, glare, the more significant. (2) light source location factor: the closer it gets to the line of sight, glare, the more significant. (3) the light source appearance size and number of factors: the apparent area, the greater the number of light sources, the more the glare, the more significant. (4) the surrounding environmental factors: environment brightness is dark, eyes adapt to lower brightness, glare also becomes more significant. Dazzling light not light, but for the concept of lamps and lanterns. Leds - t8 fluorescent lamp has been rise, are alternative Fluorescent lamp market, due to the lamps and lanterns is ready, can't change, leds - t8 fluorescent lamp needs to ordinary fluorescent effect Fruit near, thus formed the concept of glare. Anti glare products, need to consider the brightness of the led, led between the row Cloth, spacing, the led itself to the distance of the optical cover, the shape of the optical cover, light transmittance, etc., rather than simple Shell or configuration problem.
- Q: Long amount of brand of LED desk lamp capacitor charging Fried v100uf 50
- This kind of LED desk lamp, 220 v power supply is to step down by means of capacitance current limit, once the no-load, after rectification voltage will be increased to 310 v, 220 v x under the square root of 2), seconds kill the capacitance of the withstand voltage 50 v. So this failure, you must first check whether the no-load and load of power supply circuit is normal battery, check the battery cables are broken, the charging current limiting resistor is burned, if these are no problem to check current limiting capacitance itself isn't breakdown (usually the breakdown causes 220 v over-current, empty trip meeting).
- Q: Plug-in socket 12 led small desk lamp What is its battery model, the input and output voltage of each?
- 4.5 V to 6 V dc power supply, 12 leds is divided into three groups, each group of four, in parallel, each group of string a 60 euro / 1 w resistor
- Q: Led energy-saving lamps are easy to break
- Don't usually, LED lights so far is one of the longest service life, and environmental protection and energy saving, good friends said out of the blue, to see
- Q: Led lamp, good point light source or surface light source
- Led has blue light damage, not only with long time eye fatigue This is my least favorite Use dc after light lamp, now is very good Basic do not have the feeling of fatigue
- Q: The lamp that shield an eye is after the light lamp or led the good
- Advantages and disadvantages each generation of light source: The first generation of light source: incandescent lamp High frequency flash, blue light, radiation, tungsten wire, pollution is small, power consumption is big. The second generation of light source: traditional fluorescent lamp High frequency flash, blue light, radiation, mercury pollution is serious, the high frequency ballast. The third generation of light source: high frequency fluorescent lamp, the lamp that shield an eye, energy-saving lamps) Low frequency, blue light, radiation, high frequency electronic ballasts, alternating current (ac) light exchange tubes produced by stroboscopic light can cause eye damage the cornea and iris, causing fatigue and decreased vision, also makes them similar neurasthenic symptom such as dizziness. The fourth generation light source: LED the desk lamp that shield an eye (brands such as: children see treasure, philips, op, good vision, good light, Ming can reach, Edward, xiao, crown) Blue light (led) unique, no stroboscopic, no radiation, has the rich lighting products, low energy, mainly used in large-scale landscape lighting. The eye effect is that use adapter output low voltage dc, basic no stroboscopic, light color temperature range can be more widely, the disadvantage is that the light of the chromatography is too narrow, and has not eliminate blue light, blue light composition is too strong, easy to cause irreversible eye disease, not suitable for high environment with its eyes. Fifth generation light source: dc the lamp that shield an eye (brands such as: after light) No light, no stroboscopic, no radiation, high price, the visibility is small, single product, the mature dc technology, using the transformation output dc dc ballast light dc lamp, lighting area is generally larger, can be applied to high environment with its eyes.
- Q: The service life of LED lamps and lanterns is true?
- Theory is a 30000 h - 50000 - h (semiconductor diode). 1. The chip encapsulation (not the same environment, affect the life. And the light bulb how to low the situation is not possible, this is a standard) 2. The power drive power supply (electronic products, general is 2 years,) 3. The lamps and lanterns, the whole life is a long time, generally 2 to 3 years.
- Q: Hurry, common desk lamp is ac or dc output, and energy saving LED lamp?
- Common desk lamp is communication, voltage 220 v, 12 v in the majority; Most energy-saving LED lamp is a dc output voltage international big brands is 9 v, domestic brands generally 12 v.
