Q:LED lamp with air leakage to help the thunder?
No help.The leakage switch only appears on the circuit of the output end of the switch, the leakage current exceeds the set value automatically, and the utility model plays the role of protecting the output terminal.But the lightning stroke does not have the protective function to the leakage switch.
Q:What is the price of the LED street lamp from 30W to 60W? What are the advantages of the LED street lamp?
Light emitting diodes (LightEmittingDiode, abbreviated as LED) is a semiconductor pn junction formed with weak electricity can light high efficiency solid-state light source based on the forward bias voltage and the injected current, injected into the P region of the hole and injected into the N region electron in diffusion into the active region after radiation and emit a photon, electric can be directly converted into light energy.
Q:In the solar street lighting system, who is the LED driver connected to? How to choose the LED driver power?
It is based on a few strings and a few beads to choose, of course will also consider the power, are generally mounted to the lamp holder, but now generally used one of the cross flow controller
Q:How to distinguish whether the LED lamps glare seriously, whether there is a standard?
Glare is not the light source, but the concept of light. At present, led-t8 fluorescent lamp has risen and is replacing PuThrough the fluorescent lamp market, because the lamps and lanterns are ready-made, cannot change, the led-t8 fluorescent lamp needs to the ordinary fluorescent lamp effectAs a result, the concept of glare is produced. Anti glare products need to take into account the brightness of the LED, the rows between the LEDCloth, spacing, led itself to the distance to the optical cover, shape of the optical cover, transmittance, etc., rather than simply outsideA problem of shell or arrangement.
Q:How to identify LED street lamps do well or not?
What is the light source efficiency of the luminaire, that is, the power factor, which is generally above 95%.
Q:What do you pay attention to when choosing LED street lamps?
First, we should pay attention to the relevant photoelectric properties (such as light type, luminous flux, luminous efficiency, color temperature, power, rated voltage and current parameters);
Q:What are the standards for LED street lighting?
Light efficiency, the good light theory is 100lm/W, 100 watt incandescent lamp is about 1200lm, that is to say, about 12W LED lamp luminous flux is equivalent to a 100 watt incandescent lamp, this is the origin of energy saving. Of course, in fact only theory, but also the specific consideration of power loss of LED, loss and attenuation of photothermal divergence, and so on, is not to say, here is not to write.
Q:Does the LED street lamp 80W or 100W need to be compensated by a single light capacitor?
Traditional high-pressure sodium lamp street lamp end voltage is low, use compensation capacitor, otherwise the voltage is too low, it is difficult to start. LED street lamps rarely use capacitive compensation, because now LED street lamps are using wide voltage drive power, and some start voltage is below 100V, can be lit normally.
Q:How much solar panels do you need to make a 15W LED solar street lamp?
According to your work time and the continuous rainy days, and then calculate the power: LED * * working time of continuous rainy days = depth of discharge battery (AH) battery discharge depth / sunshine time / silicon solar panel power = charging efficiency
Q:What are the requirements of the LED street lamp chip? How big is it? How many will it take and how big is the distance between them?
Do you want integration or single kernel? Integration, you have 10W, 20W, 30W, 50W, 70W, 100W (single).
