Q:The LED lamp can change the light bulb
LED desk lamp is small current is energy-saving lamp, lamp power current too big, want to use have to change very troublesome, some parts to replace. The LED desk lamp is to protect the eyes and the light bulb is 50 hz frequency of eye fatigue.
Q:Home to buy led desk lamp is broken? Can someone fix it?
Led lamp production line is simpler, less complicated, general physics students will know their internal circuit structure, can also according to their own learning physical knowledge for repair, is a master of his own academic degree. If not, it may as well borrow coup. Led desk lamp is broken do next the third case is the light switch to normal, the general desk lamp can have between dark and light switch, if so, could be the governor, the interface carefully check, is there any loose or not, whether the governor is out of order, if the governor bad needs to be replaced, just stepping up strong interface
Q:LED lights it is transistor luminescence is not pure resistance filament bulbs, when dimming voltage changing, the frequency is changing so affect rectifier, sudden high voltage will burn out the LED.
Energy-saving lamps, color rendering index above 80, it has a variety of color temperature. Read a book, I suggest to use 4000 k; High color temperature advantageous to concentrate, but Dazzling; Low colour temperature of concentrate. When reading a book, lamp writes a 1.5 meters, 300-350 lux. So-called energy-saving lamps, is high frequency, otherwise, it is not energy-saving lamps.
Q:Charging indicator has been on desk lamp, led lamp is not bright after rotary switch
Hello, if you have a multimeter, please measure the lower limit of flow resistance, the lamp easy to burn current-limiting resistor, especially when charging turn on the light. Visual blue that resistance to fire.
Q:LED lamp in the 4 v lead-acid battery charging problem!
4 V lead-acid battery discharging termination voltage 3.8 V, charging termination voltage should be around 4.6, the last is constant current charging mode, constant pressure finally, 8 to 10 hours with commonly used charging current (one 8 of the charging current of battery Ann hours). I hope it can help you.
Q:LED rechargeable lamps learning how many watts?
From my experience, using LED lights 1 w to 3 w. Range so big because the LED chip quality is uneven, see what is the quality of.
Q:Led the desk lamp, electronic calendar watch how to adjust?
In normal state, the LCD screen display ALARM logo above the "ALARM", according to "bring" button to open/close to sleep function, the LCD screen above "SNZ" logo will display and not accordingly. In normal state, press "▼" button to open/close function of music appreciation. When open circuit play 7 different music. In normal state, press "SET" key Celsius/Fahrenheit temperature conversion can be realized. In the above calendar clock operation, 1 minute, if no buttons are automatically return to normal state
Q:I had had a 20 leds rechargeable lamp, then the battery is broken
The desk lamp of you already can charge (should be 220 v) you can directly with charging power supply should be bright?
Q:LED dual-mode folding desk lamp on external what meaning be
Dual mode, it is to point to can use ac and dc two modes of desk lamp power supply. Both external and internal, and ultimately to the LED lamp bead above, must be dc power supply.
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.
