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 much is the price of a LED street lamp?

Of course, because of the quality of the project involved in the maintenance and follow-up maintenance services, the price of another talk.

Q:What's the difference between a solar street lamp and a street light complementary street lamp?

The system comprises a solar battery component part (including bracket), LED lamp, control box (with controller and battery) and lamp parts; Jin Zhan solar panels light efficiency reached 127Wp/m2, higher efficiency, is favorable for the wind resistant design of the system; the cap portion with 1W white LED and 1W yellow light LED integrated in printing the circuit board is arranged in a certain distance matrix as plane light source.The control box body is made of stainless steel, and the utility model is beautiful and durable, and the maintenance free lead-acid battery and the charging and discharging controller are arranged in the control box. This system chooses the VRLA battery, because of its little maintenance, so it is also called "maintenance free battery", the system is conducive to the maintenance cost is reduced; the charge and discharge controller both functions in the design (with light control, time control, overcharge protection, over discharge protection and reverse protection etc.) and cost control, to achieve a very high price.

Q:Where can I buy LED street lamp and aluminum alloy shell, what's the quality of the product? Who can provide?

Where can I buy LED street lamp and aluminum alloy shell, what's the quality of the product? Who can provide?

Q:What is the voltage of the street lamp? What about LED?

LED are generally DC voltage, a wide variety of categories: such as the common 12V-24V, 1.8~3.8V, special 220VAC.

Q:How can a LED street lamp protect against lightning strikes?

One is the external lightning protection system, and the other is the internal lightning protection system, which complement each other and complement each other.

Q:How to connect the lightning arrester of LED street lamp?

What kinds of lightning arresters are included in the LED lightning protection device?As with other LED lamps, street lamps, the design itself has lightning arrester parts, whose parameters are usually 5kA, maximum 10kA, such protection in the usually large urban environment can be so, but the road, mountain, river water, lightning prone batter environment is not optimistic.

Q:What is the function of the microcontroller on the LED street lamp?

In the LED street lighting scheme, the microcontroller should be used to tune the PWM input, or FM

Q:The same brand of chips, how to judge the quality of LED lights?

Pay attention to the LED chips used in LED street lights. LED chip is the core part of LED street lamp, and the quality of LED chip affects the service life, brightness, light color of LED street lamp, etc.. The general import LED chip slightly better quality (such as Puri and CREE) as a municipal engineering, personal recommendations in addition to the two kinds of chips are not other, Liaoyuan century products outdoor Puri CREE, indoor use of wafer,

Q:What is the luminous flux of LED30W solar street lamps?

If it is accurate calculation method, we need to go to a professional testing center to test, our products are detected by Shanghai electric light source, and the corresponding test data is satisfactory.
