What is the general price of the 20-meter-high pole lamp in the sports park square?
Release time:
2023-01-04
The 20-meter high pole lamp is a kind of high pole lamp with high performance-price ratio Z and strong practicability Z. From the sales of high pole lamps in the whole lighting market, the annual sales volume of high pole lamps with a height of about 20 meters accounts for 70% of other high pole lamps. The unique value of the 20-meter high pole lamp can be seen. In my opinion, the high-pole lamp with a height of about 20 meters has the following two advantages.
1、 Strong adaptability: The height of 20 meters can meet the night lighting requirements of most squares. In the roundabout of the expressway, the height of 20 meters can not only avoid the 10kV high-voltage line properly, but also bring more clear lighting brightness to the driver friends without too much power light source.
2、 Cost-performance ratio: If a set of 40-meter high-pole lamps costs 120000 yuan, will the 20-meter high-pole lamps cost 60000 yuan? This kind of reasoning is very logical, because the height difference between them is half, but in fact, it is not so. The 20-meter one is much cheaper. First of all, let's look at the caliber and wall thickness. The conventional caliber of the lower section of the 20-meter high pole lamp is about 500 mm, and the wall thickness is usually about 8 mm, while the 40-meter high pole lamp is different. The lower caliber of the 40-meter high pole lamp should be at least 750 mm, and the wall thickness should be at least 12 mm. This data is very intuitive, and can be calculated by those who do not understand it. The raw material alone is more than half.
The second is the light source. The ideal lighting power of the 20-meter high-pole lamp is about 6400W, which is equivalent to 16 400W high-pressure sodium lamps or metal halide lamps. This highly configured light source with this power is perfect. However, if the same 6400W light source is equipped with a 40m high pole lamp, the effect is really not "effect". If the 40-meter high pole lamp wants to achieve an ideal lighting effect, at least 18 1000W lamps should be installed. Of course, the cost can be imagined.
Then there is the foundation. The length, width and height of the foundation pit of the 20-meter-high pole lamp are 2 meters respectively × 2 meters × 2 meters, a total of 8 cubic meters of concrete is required. The length, width and height of the foundation pit of the 40m-high pole lamp are 3.5m respectively × 3.5m × 3 meters, a total of 36.8 cubic meters of concrete is required. Isn't it difficult to see the gap?
It can be seen that the 20-meter high pole lamp is a well-deserved high-performance functional lamp, which is both economical and practical.
