Q: How about the installation and subsequent maintenance of LED garden lamp?: The maintenance of garden lights can be divided into two steps:1 、 external maintenance of lamps and lanternsThe solar garden light is often exposed to the outdoors, often through wind and rain weather, so the lamp above the general solar LED garden lamp will have more dust, can regularly with a clean cloth to wipe the dust, to keep the lamp post clean as new. When wiping, should pay attention to wipe in one direction, the action should maintain moderate and appropriate strength, and in the fragile parts clean, remember to move gently, lest many parts cause damage;2 、 interior lighting maintenanceThe interior of the lamp is clean, and in some cases the bulb is cleaned. At this time, should guarantee the first turn off the lamp, and then remove the lamp bulbs do wipe, such steps will be safe. If you want to wipe directly, please be careful not to tighten the bulb too clockwise, or the bulb will peel off too tight. Solar LED courtyard lights use a lens light source, effectively avoiding this clean-up problem.

Q: Is the LED courtyard lamp cold?: How many degrees below zero are you? Have you ever seen a duck cold? Ha-ha

Q: How to install the garden lamp?: Affordable solar garden lamp factory, it is suggested that you can go to Huangchuan Limin technology solar street lamp factory, you can customize the production of a number of solar garden lights.

Q: What's the quality of the solar garden lamp?: LED series parallel connection and PFC power factorElectronic components work within the rated voltage range, the smaller the current, the longer the heating life, and the shorter the life expectancy. LED street light power beads are sensitive to AC volume, and the higher the AC volume, the worse the light comfort.Generally use electrolytic capacitor to maintain the voltage, as much as possible to reduce the output voltage, AC volume, the bottom pressure, electrolytic capacitor capacity can not be too small, capacity and output current ratio of 1UF<1.5MA, otherwise LED will appear flashing. Non isolated input terminal, high voltage electrolytic capacitor, the choice is the same as isolated, and the output capacitor is 1UF<6MA. Dimmable LED power supply at the output terminal electrolytic capacitor to meet 1UF<0.5MA.

Q: How can you tell the quality of a solar garden lamp?: Battery depends on whether the battery is a solar street lamp dedicated battery, and now there are many small companies to use the starting power for the storage battery, which will greatly damage the life of solar street lamps.

Q: How much ballast does the LED 15W lamp belt need?: The key is the light effect of LED. Light effect LED beads are currently available from 40LM/W~100LM/W, see what you buy. Incandescent light effect is about 10LM/W, LED whole lamp, if it is cheap Zhongshan goods, it is estimated that 30-40LM/W, okay, you can go to the 60-70LM/W, PHILPS light Expo in the sample displayed, you can go to 90LM...The LED lamp uses a constant current source, not a ballast, and the output power of the constant current source should be greater than 100W, and the specific value depends on the setting

Q: How can the LED outdoor lamp be grounded?: One end of the wire is connected to the LED shell, and the other end is buried close to the ground.

Q: What's the size of the courtyard lamp?: Just apply the courtyard lamp installation is a list. The earth electrode is listed in a separate list. The hospital should be in the lamp base construction drawings, by the civil remember.

Q: How to determine the power of LED street light?: It is difficult to determine the power of the LED street lights used on a particular section of the road, but it can be estimated from the street lights seenThere are a lot of a lamp of general LED lamp, according to a count of each tile
