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:The advantages and disadvantages of LED the desk lamp that shield an eye
Desk lamp generally used in reading, writing, design, and reviews and other office or study lighting etc. To people who do the work of a desktop, maintain a good visual environment in the work place, to improve the quality of learning and office, improve work efficiency and protect the healthy body is very good. In the use of desk lamp, if low light intensity of illumination and color rendering, and can cause readers visual fatigue, long-term and well-lit stroboscopic or glare can give a person the visual nerve system bring serious harm, so it is important to pay special attention to the quality of the lighting. Only fully analyzed characteristics and choose the right lighting lamps and lanterns, to make our study and work more comfortable and happy, at the same time, make life become more rich and colorful, from the perspective of satisfy human lighting comfortable, healthy and in consideration of energy saving. LED the desk lamp that shield an eye main drawback is as follows: (1) quality is uneven, the LED industry low barriers to entry, all kinds of LED chip quality difference is very big, and ordinary consumers can't distinguish between, so the market is random (2) the start stage, landscape lighting, LED lighting is mainly applied in large environment, with eyes, is not suitable for high current is given priority to with test (3) the blue light intensity is high, the blue light damage is strong, the eyes very vulnerable
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: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:Of tubes is said to be good, and some say good leds, which is really good
I'm not professional, I think the lamp that shield an eye is a concept. It doesn't matter. Conditional or get a LED, more fashionable. A long service life, the power supply is not bad, can be used for the rest of your life. Strong, not easy broken. Finally is integrated packaging, light emitting area is relatively larger, and no more light of shadow.
Q:Do leds have ultraviolet radiation
LED is characterized by single band, the wavelengths are generally above is 390 nm, uv to less than 380 nm, so there is no uv components
Q:LED bulbs can put in the desk lamp of adjustable brightness?
Bad,, it will damage the silicon controlled voltage regulator, The desk lamp of adjustable brightness can only answer the incandescent light bulb
Q:I had had a 20 leds rechargeable lamp, then the battery is broken
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 and energy-saving light which good? To solve the
1, energy-saving lamp production process and use waste mercury pollution, the current western countries of mercury pollution is quite seriously. People also more and more realized the dangers of mercury pollution. Led light environmental protection, no mercury harmful substances. The LED assembly parts can be very easy to tear open outfit, no manufacturers recycling can be recycled through other people. 2, because it is energy-saving lamps glass, easily broken, bad, bad installation. The led solid-state encapsulation, belongs to the cold light source type. So it is very easy to transport and install, can be in any tiny and closed equipment, not afraid of vibration, basically don't have to consider heat dissipation
Q:Light flashing, if is to use the adapter, it is possible that the adapter, try out in later.
This seems not, but can be modified, specific how to operate, can go to the shenzhen LED lighting look at technical articles on net
