Q:Why is the higher the current, the lower the light efficiency?
What I know is: junction thermal resistance, spectral distribution drift
Q:30W LED solar street lamp 6 meters high, about how much?
Packing, excluding freight, tax, installation fee, approximately 1650-1750, too low, possibly of high quality, too high to be pit. This suggestion is supplied by brilliance lighting, solar street light brand manufacturers, for reference only.
Q:The power supply voltage of LED street lamp is the same, but the wattage is different. Can the power supply be general?
Completely different, power refers to the source of electricity is what, the adapter refers to the power supply does not meet the needs of electrical appliances, the installation of another device called adapters
Q:How to select suitable driving power for LED street lamp
A high pole lamp power, there are some low power courtyard street lamp, a power voltage, there are low, are prone areas in lightning, so the constant current drive, not only good performance, but also can be good heat dissipation, anti lightning, anti rain.
Q:What is the role of heat phase change material on a LED street light?
I think that a product is not only from raw material to it, but also from the process of enterprises to work on each detail can be improved, with innovative thinking to consider the product of each process! Closely grasp the quality, seize the service. Treat the product, you want to treat their children, in order to make the product to perfection!
Q:How much is the LED street lamp?
Should not be cheap, power 200W or so, the main driver expensive
Q:What is the principle of constant current power supply in LED street lamps?
Inductors, coils, transformers, these inductors are switching power components, one of the main characters,The role is to assume load or pressure, isolation, filtering and so on.All other components, resistors, capacitors, and protective elements are used.
Q:What is the difference between solar LED street lamp and ordinary energy-saving street lamp?
1. from the purchase and installation cost, LED solar street as general lights are more expensive, but without the solar street lamp cable as set up, just dig a hole and the embedded parts, battery, lamp base buried secure can, so many cable and labor costs, in fact, the price difference between divergent and general lighting.2., from the use of the role of view, LED solar street lamps using the latest LED light plate, lighting effect is generally more than 2 times the energy-saving lamps, and more energy saving role, self-sufficiency in the form of power supply is also unmatched by general street lamps.3., from the quality and after-sales point of view, LED solar street lamps choose hot galvanizing and other high-tech skills, the use of data is much higher than the general quality of street lamp poles. Today, the LED solar street lighting industry is in high-speed development period, many solar street lighting manufacturers after-sales service is also close to, as if the perfect situation.
Q:What is the actual service life of the LED street lamp?
In good heat dissipation, rated current work, with constant flow drive, high quality LED life up to 50 thousand small season
Q:LED street lamp or solar street lamp?
Solar street lights are catching up with overcast weather by the possibility of insufficient power supply. The biggest problem is that it is not suitable for long-term use. Because its battery life is only 5, 6 years.
