- Q:Led charging folding desk lamp it can directly plug
- Most can't plugged directly, that kind of desk lamp without charging control circuit, as long as you don't put it down from the socket, I have been to the battery. The lamp general charging about 10 hours, evaporation of charging can lead to lead battery, the electrolyte (dilute sulphuric acid) concentration increases, serious shorten the service life of batteries.
- Q:How many watts of led the desk lamp that shield an eye with good students
- If you can just can buy the dimmer Six or seven W has super bright commonly Look at those general is only 3 w LED bulbs
- Q:LED rechargeable lamps learning how many watts?
- Regular household study led desk lamp 5-6 w, that is using high power led, led rechargeable table lamp is the 20-30 extremely small straw hat head led luminous efficiency, power consumption province, but also greatly droop, life is not long, be in commonly 2 w or so, the new is very bright, after half a year can significantly dimmed, up to 2 years scrap (even if the led hasn't completely extinguished, but the battery is broken, can't charge electricity)
- Q:How many watts of 10 square meters of the bedroom with led bulbs Warm white or white
- LED bulb specifications now have 3 w, 5 w, 7 w, 9 w is common, like how to buy big brand certainly better brightness, 5 w and close to the original energy-saving lamps 10 w, about half is the province. 10 square room seeing you is what lamps and lanterns, with an estimated 5 w and 7 w enough. Warm white or white look like, do you want to create a warm environment, for example, the preferred warm white, want to feel a little bit bright choice is white.
- Q:Hurry, common desk lamp is ac or dc output, and energy saving LED lamp?
- Ordinary is communication, LED dc, lamp is high.I hope you can help me.
- Q:Elementary school students with what kind of table lamp is the best? The LED lamp?
- The inside of the LED blue light to the child's eyes hurt too big, not afraid of a child eyes blind ah, countries are now in the formulation of this standard. Who will dare to give the child with ah, this two days news every day in this topic. Because the light emitted from the LED is blue light, decomposite other phosphor powder into a white light, but is will gradually decay phosphors, blue light will not decay, and so blue light will be more and more, will be more and more big to the harm of eyes.
- Q:Children lamp good choice led lamp is better
- Light yellow color choice, because yellow is the most natural of incandescent lamp, filament light, an electric current passes through the great filament resistance filament become warm glow. Such light is continuous, no flash frequency. And white light is known as fluorescent lights from energy-saving fluorescent lamp, etc. Energy-saving lamps and fluorescent light stimulate phosphor luminescence principle is to use some kind of radiation, like light is discontinuous, which is a seaside sparkle, but quickly, eyes have a vision for the role of, feel the light in a flash. In such a light for a long time is bad for your eyes.
- 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:There are several major disadvantages of LED lamps
- Small LED lamp bead, loss of a few years later will slowly to change, easy to cause the whole lamp scrap
- Q:LED lamp, lens type and light type which good,
- Besides, desk lamp, desk lamp is the design standard of infinite close to the sun, because artificial forever than nature. So now the LED lamp like stressed without glare No stroboscopic, no radiation it is for this reason, who is more close to the sun, who is better. Lens is concentrated, shoot the lamp to use more widely. But the lamp's goal is to the sun, condenser is used to make fire, not reading, so the desk lamp of type lens to eliminate. But why want to do the desk lamp of type lens? To be sure, lens type basic it is inferior goods, a treasure to 28 yuan still pack mail. Because it is very low, LED brightness is not enough, so I had to use a lens to concentrated, more brighter. Here again there is a drawback, because leds are more than one, generally has more than 20 a desk lamp. Every one have a focusing lens, the end result is to write ghosting, seriously affect vision. So, choose planar light is better, the use of the sun in the standard.
