Certainly not, didn't understand such a simple truth. What are you look at the battery cell, average is 1.5 v dry cell, lithium battery is 3.7 v, and then see how sections parallel to calculate the voltage, if it is 5 v, just get a phone charger turn appliances, and then give you the lamp power supply.
Q:LED lamp is broken, put it down, things do
Using the multimeter, diode first gear test lamp bead is damaged. Then find a chip, CL BP OB or PI, NXP driver chip both at home and abroad, and design a constant current drive power supply. Of course also need to look at your desk lamp lights, string and how. General desk lamp is the output of 0.3-0.35 - A, your driver can be designed so that the output current.
Q:Desk lamp good still tube of good to buy LED strips?
Good light source directivity, on-demand lighting, as an emergency lamp is better. 2, small volume, the LED is basically a small chip is encapsulated in epoxy resin, and so it is very small, very light. 3, intensity of illumination is enough, meet the demand of your general illumination.
Q:The LED fluorescent lamp color temperature probably how many is the best
Recommend the answer seems to had mixed color and color temperature. Color temperature is lamp environment, generally the color temperature of lamps and lanterns around 2000 k to 8000 k. Below 3000 k, called warm; More than 5000 k for cool color to move; Recently, between 3000-5000 k is defined as in the temperate zone. Color temperature has no good or bad, is built in design and lighting designer in accordance with the choice of theme design intent. In general, dining room, bedroom sweet place choose warm color to move, such as office, classroom choose cool color to move. In the temperate zone in recent years, mostly used for multifunctional facilities, but also be used office, interpreted as tempered let work environment atmosphere.
Q:What LED lights so easy bad ah?
You choose the wrong factory, general theory of LED life span is 50000 hours, the actual use also in 35000 hours. Three months is bad, is basically not well-known chip in China. Now we are doing the LED business, foreign customers require minimum is Taiwan wafer chips, and some domestic retailers order chips are the most time, because Chinese people cheat, also bad complaints after seduced. Don't mind the price to buy the philips, their quality must be guaranteed. The good and evil people mixed up domestic factory, see you luck
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:LED desk lamp and ordinary lamp which good?
Hello I am a LED lighting manufacturer, the production technology has a certain understanding, summarize the advantages of LED lights at environmental protection and energy saving And because of the waves of light Not to attract mosquitoes, the concept of energy saving is a less equal the brightness of the consumption of electrical energy, high-end products can consume 3 points 1 original electricity can make the same brightness, but now LED market chaos, so the high price you may not buy high-end products, common in saving electricity is some two points 1, to the eye, because of the LED constant current source, belongs to the high frequency flash, the human eye cannot be sensed stroboscopic so high, so does have some eye effect, of course, look at your LED desk lamp design, the design of the lamp shade some of them are the light of the lamp bead direct injection would be dazzling eyes,
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
