- Q:The LED fluorescent lamp color temperature probably how many is the best
- In addition, need different environment illumination light color is also different. The household environment, for example, if the sitting room with warm white lighting, can appear dark, stuffy, narrow space; Bedroom, bathroom with cold white light, can appear cold and stiff and lack of emotional appeal again. Dining room lighting light color can require the full performance of food color, too slant blue light of cool color, will look stomach-turning dishes
- Q:Led lithium battery lamp, 0.5 a rated input current search. With the output of 1 a charger or mobile power no problem?
- Here need to popularize A common sense, when you LED lamp or cell phone, the above label for 5 v 0.5 A charging parameters, the charger you even 5 v 100 A, you put the LED lights or cell phone plugged into the charger in, is safe and reliable, not because the charger is 100 A, think at this point is to use 100 A for your LED lights, mobile phone recharge, 100 A here refers to the charger output capacity can reach 100 A, it can at the same time for the 200 only 5 v 0.5 A LED lamp, charging the mobile phone. 220 v voltage is like family, when your family power supply power supply capacity of 10 A, he can light up 100 22 w bulb at the same time (220 v * 0.1 A = 22 w), A light bulb is 220 v 0.1 A, even if you only opened up A light bulb in the home, the light bulb will not burn because of the power supply capacity of 10 A. When A family with only one bulb light, at this time is 0.1 A current through the bulb, rather than 10 A.
- Q:When did you buy? If it is just bought, suggest you use first photoelectric charge again
- LED, LED because of the different luminous principle, eliminate the stroboscopic and has high photosynthetic efficiency and pursue higher photosynthetic efficiency potential Advantage is small volume, no stroboscopic, including UV, high light efficiency, using high quality chip (OSRAM, day, and the name of the CREE) products can reach more than 80 or 80 color and has a long life The disadvantage is that the current national standard uncertainty, the products on the market anomalies chaos, most manufacturers use inferior chip led to less than 50 color... And LED chip due to poor use drive electric power are different, such as chip array and flashing brightness difference problem In a word, If conservative and don't care under the condition of light, it is best to use halogen light source to read; Care about energy saving problem use energy-efficient light bulbs, but must pay attention to choose big, because of the small manufacturer use halogen powder phosphor color rendering index less than 70, the same is not suitable for reading; If the pursuit of high-end, strict energy-saving, wish longevity noodles and the modelling of traditional light source, can choose LED products, but the best choice in the lighting industry's top brands and formal channel, so as to the quality of the products
- Q:Three months ago I was full of electricity, this three months I was useless, now basic is full of electricity, use need not use a few hours to recharge first? Or direct charge?
- Make sure you are li-ion battery or lead acid, lithium electric light and dark are used to also go, lead-acid was at any time, then keep full electricity to save battery.
- Q:LED rechargeable lamp, battery voltage is how many v?
- Using is a kind of super high brightness LED flashlight, its working voltage is higher, generally 3.35 V - 3.65 V, working current is relatively large, at 30 ma -- -- -- -- -- 50 ma, high brightness. Above is reproduced, the following is what I write. You can also in the baidu search is known here. 1, rechargeable lamps with light emitting diode and a flashlight with should be the same. The above work should be refers to the voltage on single diode voltage. Don't know how much is the battery pressure is how even get to see that a few diode. But according to my experience, I've hurt countless this flashlight and desk lamp) 4 v battery voltage is not the batteries are lead sulfate is 6 v battery. 2, see the internal structure of light emitting diode, the bulk of the pole is negative, the light of the part is connected to the cathode, or look at like a bowl of concave portion of the attached to the cathode. 3, heard "filament" if you want to ask is "filament light source" refers to a hot filament of the bulb, tube produced by light sources; If you want to ask is "filament voltage" is refers to the added on both ends of the filament voltage. Case there is a small light bulb and a dry cell formed a closed circuit is: at the ends of the battery voltage = bulb voltage + the consumption of battery internal resistance. Usually learn high school electricity can use this relationship. 4, x ray tube, extreme conditions, the theory of complex sentence couldn't say for sure.
- 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:Heard that LED energy saving effect is very good, but in the family use, very dazzling LED? Harm to the eyes? Can not find a standard answer online, please help!
- No harm. But there is no need long time staring at it
- Q:The advantages and disadvantages of LED the desk lamp that shield an eye
- Suggest choose dc lamp At the moment there is a kind of complex light dc the lamp that shield an eye is good, with international patent. You can keep an eye on the lamp that shield an eye the lamp that shield an eye on market and other dc: one of the most essential difference between the high frequency the lamp that shield an eye (most of the domestic brand) : China's ac 50 hz, namely change 50 times per second. So direct use of alternating current (ac) electric light, are flashing, flashing frequency is commonly 100 times per second, is the grid frequency doubling, namely change 100 times per second. Other (international brand) : the lamp that shield an eye is high frequency variations of the lamp that shield an eye, not flash. Flash badly to the human eye can't see or added a filter, take temporary solution not effect a permanent cure. LED lights: not the lamp that shield an eye. LED energy-saving lamp tube is clean and healthy, but not the real meaning of the lamp that shield an eye. The first: the lamp that shield an eye is trichromatic lamp, light color is very good; And the LED is a monochromatic light source, can have influence on the color of the eye nerve, fatigue. Although its working voltage of direct current (dc), there is no flicker problem, but because of the LED chromatography is too narrow, can't use in the place with high demand with the eye, can only be applied to general auxiliary lighting (used in exterior lighting, light boxes, etc.). Second: the lamp that shield an eye is a special fluorescent tube; LED is a semiconductor light emitting diode. Dc the lamp that shield an eye: the alternating current into direct current (dc), first with dc lamps (high technical content), no flash, no stroboscopic, real and when using the light close to natural light, very bright, but not dazzling, very soft. And other kinds of electromagnetic radiation, more the lamp that shield an eye without any radiation. Of course the price will not low.
- Q:LED rechargeable lamps learning how many watts?
- Visual lighting environment is very important, family, speaking, reading and writing assignments at home to read and write operations is one of the most important learning visual lighting environment, specifically is to learn the quality of the lamp quality. Learning is a great variety of lamps on the market, there is the lamp that shield an eye, energy-saving lamps, incandescent lamp and LED lamp, etc. Discriminant learning quality of the quality of the lamp, if the light color of white, or light color dim, dazzling the desk lamp of illumination is not standard, are unfavorable for family learning source, because then there will be a bad influence on the vision of development.
- Q:Use LED lamp plant useful? Useful for which plants, which plants useless?
- LED lights line downy, spectrum pure, no ultraviolet light. 1, energy saving. 2, long service life. 3, good applicability, due to the small size of the single star LED, can be made into any shape. 4, short response time, is the ns (ns) level of response time, while the common lamps and lanterns is ms (ms) level of response time. 5, environmental protection, no harmful metals, waste recycling easily
