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: LED street lamp or solar street lamp?: If it is a simple solar light and general lighting than, it is recommended to use general lamps. To tell you the truth, the electricity charges in the province are simply not enough to invest in maintenance and renovation. Therefore, many public facilities of solar energy lamps are bad, because the maintenance and replacement costs are too high.

Q: What role does the light controller and driver play in the LED street light component?: At present, light emitting diode driver chip can be divided into constant voltage drive chip, constant current drive chip and pulse driver chip. Among them, constant voltage drive chip is generally our most common DC/DC boost chips. The advantage of this scheme is that chips are cheap and do not have complex peripheral circuits. But only constant voltage drive LED will drive the output current of the circuit is uncontrollable. LED brightness consistency cannot be guaranteed.

Q: For the LED street light distribution, is it better to use a lens or a reflector?: Lens better point: the lens can be arbitrarily better match light, mold work is better than using reflective glass, the price of natural cheap

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: The design idea of LED intelligent energy-saving street lamp: Smart streetlights, I conceived. But it's out of the industry now.

Q: What heat sink is best for LED street lamp radiator?: What is the external force of heat, force, that is to say, with the use of external heat, fan in the lamps or using superconducting tube, water-cooled, and so on, the advantage of active heat dissipation, efficiency has been improved, but the structure is complicated, the cost is increased, and the service life of the cooling equipment is generally not too long, less than 2 years is basically finished.

Q: Where can I buy LED street lamp and aluminum alloy shell, what's the quality of the product? Who can provide?: Shortcoming:1, LED packaging process is complex2, multi core integrated heat radiating shell is too concentrated, need efficient, otherwise LED decay seriously affect its service life.3, light concentration, LED low luminous efficiency, is currently around 85LM/W4, the use of multi-core string combined with the circuit, compared to a single core package, there is a high probability of reliability problems

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 is the minimum illuminance of LED street lights Emin obtained? How to calculate?: Minimum illumination Emin, if you go to calculate or use lighting software (DIALux) simulation, you can get the minimum illumination Emin, how to simulate this? This is not clear
