Q:So only the halogen lamp, but is low voltage halogen lamp, need a rectifier, and halogen lamp itself temperature is high, pay attention to the heat dissipation, color rendering index selected 90-100, color WenXuan 2700 k, the best for you.
Touch switch is a sense of application of sheet metal, unless the line on this, otherwise it will not bad. The first thing to look at you in the battery voltage is the same as in the original. In addition, it is possible that the triode inside or gate integrated piece of bad, estimate that you can't repair
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 lithium battery lamp, rated input current 0.5 a
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:Light flashing, if is to use the adapter, it is possible that the adapter, try out in later.
Because incandescent lamp and electronic energy-saving lamps in People's Daily use still occupies a very high proportion, in order to reduce the waste, LED lighting manufacturers must develop in accordance with the existing interface and habits of the people are using the LED lighting products, make people don't need to replace the original traditional lamps and lanterns pedestal and lines can be used under the condition of a new generation of LED lighting products. So the LED ball steep light was born. LED ball steep light used the existing way of interface, the screw (E26 / E27 / E14, etc.), pin (B22, etc.), and even to accord with the habits of people to imitate the appearance of the incandescent light bulb. Based on LED light-emitting principle of unipolarity, designers did change in the lamps and lanterns of the structure make the LED ball steep light light distribution curve of the basic point source of convergence with incandescent bulbs.
Q:General led desk lamp how much a led lamp is usually how many watts
Also suggested that the lamp choose warm white color temperature (3000 k), or natural white color temperature (4000 k), light color not only warm but not dazzling, long time reading or writing homework eyes not easy fatigue!
Q:Whether the LED desk lamp, luminous points: two guide plate and the patch?
Yes, with the guide plate is commonly known as the "light", luminous uniformity is better than patch directly on the shiny surface, but the cost is much higher.
Q:Three lights in parallel, and should be how the resistance of the step-down series?
What is your 6 v battery batteries? Small battery (battery)? 10 v charger to see what the battery charger, if the battery can work with, if nimh electricity or lithium electricity will reduce the voltage. How much is the pressure light bulb? It is best to parallel, serial word broke a are not lit up. Add how much resistance depends on what you use the lamp, or led. The dimming added potentiator current limiting. How to do is very simple, still with the figure? Charger and battery, lamps (and) series of potentiometer. If it is nickel metal hydride batteries can't do, for a long time will seriously affect the battery life in charging status. The more complex.
Q:What LED lights so easy bad ah?
LED drive circuit, the chip is the key to LED lights, if more than 50 bulbs also do a little wrong, so reach the technical level of domestic some manufacturer, made in the country that is imported, it is better to buy some export brand. Some of taobao mall just can also, this price can buy good LED bulbs
Q:Students do homework with LED lamp to choose LED strips or LED lamp bead?
Home purchase is a complex of light, three colors of the lamp, the light is very soft LED is a monochromatic light source, long time use of eye fatigue, can also affect the vision If you really want to buy, lights, heard that is very bad, the patch is not clear.
Q:Led and energy-saving light which good? To solve the
Mercury elements contained within the ordinary energy-saving lamps, bulbs if there is damage will affect the people safety, life expectancy 1 year, met a bad time of year also needs to be replaced, and shape is too beautiful, luminous color and warm color only white. But as a whole solid light, LED bulbs solid cold light source, epoxy resin encapsulation, service life is 5 years, 10 times the energy saving fluorescent bulbs. The installation can guarantee within five years at a time without replacement. Appearance, nobleness and luxuriant and generous. LED bulbs color colorful, such as: white, yellow, blue, etc. Can LED Lantern Festival and environmental protection, shockproof, waterproof, miniature, high brightness, easy to move light, etc.. Gradually along with the global sales plan execution, green lighting industry will rise. LED a new generation of green light source, will be in the 21st century caused a revolution in the field of global illumination. We just need to wait and see
