Q:What's the reason why the LED street lights don't work?

The LED lamp power is waterproof power, bad to change new power protection function is not perfect, directly affect the quality of fault phenomenon LED lamp 2, bad part there are several possibilities: 1), such as LED lighting power supply for multi-channel constant output, which may be a group of bad, 2) is LED chip is not good, or is the LED lamp cooling caused by bad burn LED chip.

Q:How to choose LED floodlight?

The leakage current is also very important, LED floodlight is a one-way conductive luminous body, if the reverse current is called leakage, the leakage current of LED, the service life is short, the current is a little larger there can burn the bulb, so LED floodlight of this type of price is relatively low, lighting recommendations it is best not to buy this type of.

Q:LED what's the wattage of the wall washer?

Small power wash wall lamp: use a small power chip beads, a 10W, 12W, 15W, M. The length of the wall washing lamp can be cut, and it will take as long as possible.

Q:How many watts of energy saving lamps are suitable for the three meter courtyard lamp? How many watts of LED?

The same brightness, if LED to 10W, energy-saving lamps about 30-40W, incandescent lamp to 100W, three meters height 10W enough, solar street lights 5 meters high, only to use 12W, it is very bright

Q:I want to use remote control LED lamp to do the infrared emission of the camera. Is that ok?

The LED power in the remote controller is very small, and the infrared emission of the camera may be too small.

Q:Led brand lights, floodlights, projection lights, outdoor lights, which brand is good?

The lamp body is made of steel, glass and silicon rubber are sealed, and epoxy resin is embedded to ensure the superior waterproof performance of the lamp. Light source with high power LED chip, built-in constant current drive power. You can go to the website to understand.

Q:Installation height of outdoor lamps is generally not less than meters

When the design is not required, the installation height and the voltage level of the luminaire shall comply with the following requirements:1 general open type lamps and lanterns, the distance of the lamp head to the ground shall be no less than the following values (except when the safety voltage is used):1) outdoor: 2.5m (outdoor wall installation);2) Workshop: 2.5m;3) indoor: 2m;4) soft wire lamp with lifter in suspension after the start of 0.8m.2 dangerous and special dangerous places, when the luminaire is less than 2.4m from the ground height, use rated voltage of 36V or less lighting lamps, or have special protective measures.19.1.6 when the luminaire is less than 2.4m from the height of the ground, the proximity of the luminaire must be grounded (PE) or zero (PEN), and the grounding bolt shall be provided with an indication.

Q:What is the distance between the usual street lights?

There is no standard, and some are required to achieve the value of illumination, there is no hard and fast requirements, generally speaking, the distance between the street lamp and the lamp height and the number of watts.

Q:What happens if the LED street is ungrounded? Is it a big problem?

The LED itself is very sensitive to lightning surge currents, which can cause damage to the human body by electrostatic touch and burn chips or leads. Therefore, the street lighting circuit must be grounded.

Q:What is the LED wall washing lamp? What is the function of the wall washer?

The LED light projector is approximately the same. Compared with the circular structure of the LED light projector, the heat dissipation device of the strip structure of the LED wall washing lamp is better treated.Now, LED wall washing lamps have gradually replaced other kinds of landscape lighting fixtures, and the future applications will be more and more extensive. LED wall washing lamps can be used outdoors, indoors and squares,
