- Q:Why is the higher the current, the lower the light efficiency?
- Because the higher the current, according to Ohm's law, of course, the power will also increase, while the luminous efficiency is the total luminous flux / total power
- Q:What are the 6 main disadvantages of LED street lights? What are the 6 major disadvantages?
- 1 single LED power low. In order to obtain high power, more than one parallel connection is needed.TwoLow color rendering index.It is a technical problem that the color displayed by LED radiation is not true of incandescent lamp, and it should be analyzed from the spectral distribution.
- Q:Street lights and signal circuit connections
- 1, the characteristics of the LED street lamp - unidirectional, without light diffused lightingEnsure efficiency; page 2, LED street lamp has unique two optical design, will be LED street lightingFurther improve the area required to save energy lighting efficiency; illumination; page 3, LED light source efficiency has now reached 100lm / W, but there is still much room for development, for 250LM / W reasonsThe luminous efficiency of high pressure sodium lamp is only increased with the increase of power; therefore, the enterprise list, the overall luminous efficiency of LED street lamps is stronger than that of high-pressure sodium lamp; (overall light efficiency is theoretically practicallyOver 250W high pressure sodium lamp is more efficient than LED.
- Q:What is the display index of the LED lamp?
- For LED lamps, the average color index of the three primary colors is high, and the color index of the blue and yellow phosphors is not as high as the three primary colors of the LED.
- Q:How many watts does the LED street light have?
- LED street lamp has the characteristics of environmental protection, pollution-free, less power consumption, high light efficiency, long life and so on. Therefore, LED street lamp will be the best choice for energy saving reconstruction.
- 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 many lights can a high-power LED lamp be at least W?
- At this stage of the rural minimum power lights are 20W, 40W, is mainly based on the width of pavement, street lamps light efficiency, light cloth density, the installation height of the future, the light effect is improved, the minimum power may be smaller than the current lights, high power LED lamps, small power can do big to about 80LM/W. Power can do about 90LM/W street.
- Q:What's the advantage of Led street lights?
- LED street lamp is different from conventional, LED light source adopts low voltage DC power supply, by the high white GaN based blue LED and yellow synthesis, can be widely used in road, the outer cover can be made of high temperature resistant up to 135 degrees, low temperature reached -45 degrees.
- Q:What are the components of a solar street lamp?
- Solar street lamps mainly include: solar panels, solar controllers, batteries and LED lights
- Q:What are the parts of a LED street lamps?
- The working principle and design of solar street lamp LED 2008 01 Friday 25 March 22:28 with the world energy crisis intensifies, countries are seeking a solution to the energy crisis, a road is used for new and renewable sources of energy; the other one is looking for new energy-saving technologies, reduce energy consumption, improve the utilization efficiency energy.
