Q:LED Street pressure is not enough, what will happen?
Potential safety problems, resulting in shortened service life, serious damage to the product directly.
Q:LED street lamp, glass lens, mold opening, research and development
LED based two time light distribution design is critical to the performance of final lighting devices and products. The first part of the light, failed to achieve the effective illumination range resulting in energy loss, need high numerical aperture optical system of light gathering, further improve the utilization rate of light energy; second, after packaging, image illumination uniformity can not meet the design requirements, to the lowest illuminance is greater than the value required in the choke each point of illumination, which require the LED two optical design. Ying
Q:Can the power supply for the LED street lamp be placed under the lamppost?
In fact, it is more convenient to put the driver into the electric door directly. If the later stage needs maintenance, it is not necessary to remove the whole lamp.
Q:What are the ways to save energy in street lamps?
Midnight lights: as the name suggests, in the evening when the amount of half the amount of light, only half of lighting to meet the requirements. As the voltage is proportional to the change with the load, after entering the middle of the night when the load is reduced, the voltage higher than when lights before midnight light, and at this time on the road, pedestrians and vehicles to reduce, put half the street lamp can meet the lighting requirements. The night lights have a variety of luminaire-distribution-style, many of the commonly used vibration rod.
Q:How much is the price of the LED street lamp?
Tens to hundreds of dollars range, this depends on what you focus on the LED street lights? Guoqiang photoelectric cost-effective lamps
Q:How to calculate the radiation area of solar LED street lamp
According to the light distribution, the installation height and elevation of the lamp, it can be calculated by trigonometric function
Q:Do ballast ballasts need to be used for starting the LED street lamp?
The need to drive (constant current power) rather than the rectifier does not require capacitive compensation, this is to see how much power you have, the most important is the power factor
Q:How to connect the lightning arrester of LED street lamp?
Return to a proposition. How to ground1, the lamp metal tube and the strip at the bottom of the rod grounding terminals properly connected, pay attention to the ground terminal can not save, ensure that the terminal is connected properly;2, lamp posts of movable tubes, bushings and other loose place, must be greater than 16mm woven belt two connections;3, the lamp holder and the lamp post connection must also be ditto;4. The lamp holder must have grounding terminals, and the grounding terminals must be properly connected with the lamp holder and the braid of the pole.
Q:LED technical requirement of street lamp 100W
LED light source technical requirements:(1) LED light source chip requires the use of internationally renowned brands (American CREE CREE, German OSRAM Osram and Holland PHILPS Philips), and uses low thermal resistance, good heat dissipation and low stress packaging technology.(2) using high luminous efficiency LED chip. LED chip luminous efficiency more than 110Lm/w, no ghosting, low light attenuation.(3) LED light source color temperature 4000K-6000K.(4) LED light source life: no less than 50000h.(5) the general color rendering index LED lamp: Ra = 75, the road evenness in more than 0.4.(6) LED street light 10000 hours less than 8%, the service life of 50 thousand hours, 50 thousand hours less than 30%.
Q:What is the reason that the longer the wire pulls on the LED street lamp, the lower the voltage?
Resistance will block the passage of electricity; the greater the resistance, the greater the loss of electrical energy in the line.
