Q:How many meters is the courtyard light?
The area courtyard lamp is generally between 2.5-3.5 meters high, the courtyard lamp style is different, mainly according to your district style to choose the courtyard lamp type.Also, what are the main functions of the courtyard lights, the lighting or the decoration?. Single head courtyard lights are normally lit with 150 watts of sodium light or 100 watts of energy. If it is decorative, you can use 65W warm light energy-saving lamps.
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:Is the LED courtyard lamp cold?
LED is afraid of the heat, the heat is not good, directly lead to decay,
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:Consult the advantages and disadvantages of the metal halide lamp and the LED miner's lamp
1, energy saving. 2, long life. 3, the applicability is good, because a single LED is small in size and can be made into any shape. 4, the response time is short, the NS (nanosecond) level of response time, while the ordinary luminaire is the MS (millisecond) level of response time. 5, environmental protection, no harmful metals, waste easily recycled. 6, brilliant color, light color pure, narrow spectral range, and through the red green and blue three primary colors mixed into colorful color or white. Disadvantages: 1, the price is expensive. 2, there is still a big gap between luminous efficiency and theoretical light efficiency. 3, there is still a big gap between the current life and the theoretical life (10W hours). 4, there is still a certain amount of fever. 5, can greatly reduce the light attenuation.
Q:How much ballast does the LED 15W lamp belt need?
15W light belt, the ratio of 15W-20W constant current switching power supply on it
Q:How to determine the power of LED street light?
If the LED street lamp is a block of chip, it can be installed according to the height and brightness of the street lamp, and then it can be estimated that each block is 30W/50/100W
Q:Which brand is good for the patio lamp?
Finally, check the LED driver input voltage is normal, check the fuse LED driver is not flawless and perfect, if the fuse is good, with a multimeter check LED driver output voltage is not normal, if normal, go to the street lamp manufacturers for a LED lamp, if not normal then, it would change a LED drive
Q:How to choose LED courtyard street lamp?
Through the LED courtyard lamp in several aspects, 1. installation convenience, 2. lighting brightness, 3. energy saving, environmental protection, 4. appearance and so on a few main factors, through these aspects to find out whether a courtyard lamp qualified
Q:Yard light installation manual fee
Solar street lamps use 12V power supply, it is not easy to cause electric shock, and ordinary street lamp adopts 220V voltage. Once leakage or short circuit occurs, it may cause casualties.
