Q:The difference between led grille lamp and dared light
Dared light source of light is a small lamp bead, grille lamp light source is T5 and T8 tubes.
Q:How to distinguish the LED lamp wattage?
Look at the size of shoot the light, usually different wattage of the radiator is not the same.
Q: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.
Q:How do I get the light
Shoot the lamp to generally have a lamp holder, transformer, lamp cup plug into the socket, lamp holder line received 12 v low voltage output from the transformer online, on the other side mark 220 v line and zero line. Under normal circumstances, the power supply lines to diameter need to match, according to the total wattage lamp don't overload, easy to cause line heat causes fire hazards. As for the integrity of the design and decorating can such as first place, and where there is injury can mend the great white, scratch putty in general. (this is simpler, prevent the remodeling of large area)
Q:What do you need for homemade LED lights
Monitor by using infrared transmitting tube to do, Projection lamp, if do you want to make sure the power supply, generally use the 9 v or 12 v dc power supply, the LED can use two methods of series and parallel mixed, coupled with the size of the resistance to control current, as long as 20 ma lighting.
Q:Excuse me, If no ceiling can hold the LED lamp?
Is two kinds of rail type with the shoot the light, you need to install a track, you will orbit is fixed at the top of the strong, and then track type lamp base card into orbit, electric rail, shoot the light will be bright
Q:What is the difference between LED GU10 and ordinary lamp
In the same class, shoot the light some more expensive. In general a better quality of domestic canister light lamp brands have op, three stand, leishi, mitsuo aurora. Among them, leishi and three best cost-effective. Canister light usually have a big (5 inches) in the (4 inches) small (2.5 inch) three. Trumpet the current market price is between 20 to 15 yuan, 28-32 yuan between, medium size between 36 to 48 yuan between. All prices above do not contain light source, of course. Canister light have horizontal and vertical two, flat a little more expensive than the vertical. Is important to note that close exposure lamp generally cannot be used for wool fabric, also can't close any flammable obstacles, otherwise easy to cause fire. Although the lamp power consumption but more in place with its ornament effect. Shoot the light as well as distinctive flavour to the adornment of the five lights cup.
Q:The LED lamp which cheap compared with bovine eye lamp
Bovine eye lamp is not practical, or LED days lanterns commonly used, so the shell will be much cheaper, good less people with bovine eye lamp so shell is especially expensive.
Q:How to detect the LED to shoot the light quality is good or bad
When many people in the use of LED to shoot the light, because buy the price so low in the ceiling to appear some problems, a lot of use chip production line lay out to make, do not match color temperature, brightness difference, short service life, the user need to pay attention to.
Q:The original old how long pole to shoot the light to LED lights
Transform the power The lamp is with electronic transformer is 220 V / 50 hz ac DianZhuan into 12 V high frequency alternating current (ac) for the use of shoot the light, for the LED power supply. Now should be high frequency ac DianZhuan into 12 V dc 12 V, so that power can be multiple groups of three series of LED lights (in terms of each only 3.5 V), each lamp visible need more groups in parallel, in order to reach a certain brightness. To add a high-frequency electronic transformer rectifier filter circuit, it can be high frequency ac DianZhuan into 12 v dc 12 v. Rectifier with high-frequency rectifier tube, HFC L can use energy-saving lamps of the circular on the glass with plastic envelope around 10 turns the substitution. Cut a small piece of PCB on the above components on the electronic transformer, after connected with insulated wires - and into electronic transformer molded case, output leads to +, - two power supply line.
With advanced sound production equipment, testing equipment for LED packaging device manufacturing base. Keep pace with world-class technology and management. Can meet the ISO9001: 2008 quality certification system for LM-80 testing standards, establish a strict quality control system and improve product testing process to ensure stable and reliable product quality.
