The display of the LED Lighting-28W
The applications of the LED Lighting-28W
- Q:Does the LED street lamp need a starter?
- LED light is not a starter, is a constant current source module, is 220V city power rectifier, with constant current circuit to each LED lamp power supply; LED lights can be connected in series, and then parallel. There is also not constant current, but in each series of branch current limiting resistors, to consider the range of voltage fluctuations, select the current resistance resistance value and power.
- Q:400W high pressure sodium lamp can replace 150WLED lamp? Luminous flux?
- Yes, and under the current technical conditions, the life expectancy of HPS is much longer than that of LED street lamps
- Q:Is there a place where trees can hold LED solar street lamps?
- Yes, solar street lights are not covered by trees
- Q:What are the parts of a LED street lamp?
- System design ideas, solar street lighting design and general solar lighting compared to the basic principle of the same, but need to consider more links. The following will be the solar LED high-power street Hongkong Industrial Group Co., Ltd. as an example, several aspects of analysis.
- Q:What's the main reason for LED street lights?
- There are many reasons, but the most important reason is the poor quality of the controller
- Q:LED street lights installed on both sides of the road, horizontal installation and angle installation (0~30 degrees), natural convection heat dissipation, that good heat dissipation.
- Generally speaking, this is a better angle installation, and the light source installed vertically below is the best,In fluid mechanics, the density of hot air is smaller than that of cold air, small density, light mass of hot air rises, cold air sinks, and natural convection occurs. But it doesn't have to be angled, depending on the shape of your fin design and the way it is cooled.
- Q:What happens if the LED street is ungrounded? Is it a big problem?
- If a lamp holder is expensive, it should be sold for ten thousand yuan. If it is not damaged by grounding, it will be more harm than good.
- 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 luminous flux of LED30W solar street lamps?
- The luminous flux of LED light source is 1W 45mil 110lm to 130lm (this is a test at the rated 25 degrees at room temperature, in the actual application is certainly not to), regular 30wled products are a lens two with a light, even the best lens in there will be the loss of good, good quality of the lens, the loss in 10%, ordinary loss in more than 30, LED street common 30W are the traditional lamp type, the lamp outside and glass lens, the light loss is higher, so the comprehensive down than ordinary street lamp has a conventional calculation method is practical the luminous flux per lamp w lumens 0.7 is multiplied by the number of lamps, the luminous flux *0.6, luminous flux *0.75 good quality, this is probably the calculation method.
- Q:What is the voltage of the street lamp? What about LED?
- LED are generally DC voltage, a wide variety of categories: such as the common 12V-24V, 1.8~3.8V, special 220VAC.
