FAQ

What kind of transformer mr16 led lamp need!
MR16 lamp is 12 v low voltage, just to the 12 v constant voltage transformer, dc and ac can be, but the transformer power should be greater than the rated power of shoot the light a little.
Motorcycle lens and the LED lamp can be installed at the same time, and shall not affect the circuit?
Can gm is 12 v, so long as you don't pick up ballast line can be connected in series, because you is the 12 v battery
How can you make the led lamp not dazzling
Into visible light solid state of semiconductor devices, it can be directly put DianZhuan into light. The heart of the LED is a semiconductor chip, chip attached on a bracket, at the end of the end is negative, the other end connected to the power of the anode, the whole chip is encapsulated by epoxy resin. Semiconductor chip consists of two parts, one part is a p-type semiconductor, dominated by holes in it, the other end is n-type semiconductor, here is mainly electronic. But this two kinds of semiconductor connected, forming a p-n junction between them. When a current flows through a wire to the chip, the electron will be pushed P area, electron and holes in the P zone compound, then will be issued in the form of photon energy, this is the principle of LED light. And the wavelength of light was the color of the light, is determined by the formation of p-n junction material.
Led courtyard lamp long good or single head
Single head, of course, single head less waste,See your demand, to achieve what kind of lighting effect
How high is the temperature of the LED lamp?
What are you doing dongdong oh, you know yesterday in the baidu search the sa
What is the price of an led light?
Suggested that before buying compare several brands, more cost-effective choice, of course you can also online mall, usually the price will be more cheaper.
The house that new clothes builds, pick up a LED lamp Specific parameter no receive wire didn't receive zero after electrify LED lights have a dim light An estimated 10% of the after less than fully open after disconnect all electrical appliances There are light which out of the question to solve the trouble is online, etc. ~
LED lamp belongs to low pressure constant current electric equipment, want to use the power adapter when ac 220 v power supply to drive. Now the high frequency switch power supply, LED power supply is almost working frequency is controlled in 100 KHZ, input and output impedance is very high, start up easily. When turn on the fire didn't answer the zero line, power shell or internal circuit board is exposed to air, larger area to form a minor loop and outward radiation energy, cause the power weak vibration, low output voltage. This phenomenon is not obvious when the air is dry. Therefore, in order to use electricity safety and environmental protection, use LED lamps and lanterns is best according to the standard connection, namely switch must control the fire. Of course, there are still many LED lights manufacturer in order to reduce costs, using a simple capacitor step-down type power supply for the LED power supply. Because the source is a capacitive load, even after the switch wire through line can the distributed capacitance between the conduction small current, lead to LED lights dim.
Is the radio light charged?
Certainly inefficient, because want to install a set of several shoots the general, a lamp wattage is probably around 50 w, if such pursuit effect is normally open, you think down to a few hundred watts open must be inefficient.
