济南发光字对比高压钠灯的优劣分析

来源:http://www.hongchenad.cn    发布时间:2021-01-13

1、关于济南发光字的节能效果,在很多LED路灯取代高压钠灯的实际案例中,节电是一个重要的因素,但是实际的LED路灯并不比高压钠灯节电。从发光效率的比较,发光效率(80 lm / W)的大功率LED路灯远低于高压钠灯(100 ~ 138 lm / W)。尽管领导定向发光及其效率高于高压钠灯,LED路灯的综合能源效率仍低于高压钠灯由于其较低的发光效率。

1. As for the energy saving effect of Jinan luminescent words, in many actual cases of LED street lamps replacing high pressure sodium lamps, energy saving is an important factor, but the actual LED street lamps do not save electricity than high pressure sodium lamps. From the comparison of luminous efficiency, the luminous efficiency (80 LM / W) of high-power LED street lamp is much lower than that of high-pressure sodium lamp (100 ~ 138 LM / W). Although the LED directional lighting and its efficiency are higher than that of high pressure sodium lamp, the comprehensive energy efficiency of LED street lamp is still lower than that of high pressure sodium lamp due to its low luminous efficiency.
2、光色问题。目前大功率LED路灯主要采用色温在5000K ~ 6000K的白光作为道路照明光源。在视觉上过于寒冷,当距离视觉较长时,眼睛的观察能力会下降。
2. Light color problem. At present, white light with color temperature between 5000K and 6000K is mainly used as road lighting source for high-power LED street lamps. If it is too cold in vision, when the distance from vision is long, the observation ability of eyes will decline
3、目前济南发光字的成本远远高于高压钠灯。
3. At present, the cost of Jinan luminescent lamp is much higher than that of high pressure sodium lamp.
4、与使用寿命相比,济南发光字的标称使用寿命在50000小时以上,是芯片的理想使用寿命。芯片的封装、灯具的散热等因素会导致光衰减,驱动电路的寿命显然不能达到50000小时。在部分led路灯的试用中,发现不到半个月,路灯的衰减已经非常明显。
4. Compared with the service life, the nominal service life of Jinan luminous word is more than 50000 hours, which is the ideal service life of the chip. The packaging of the chip, the heat dissipation of the lamp and other factors will lead to light attenuation. Obviously, the life of the driving circuit can not reach 50000 hours. In the trial of some LED street lamps, it is found that the attenuation of street lamps has been very obvious in less than half a month.
目前高压钠灯的标称寿命已经超过28000小时,与高压钠灯及其配套器具的使用寿命相比,实际使用3-4年不成问题。
At present, the nominal service life of high pressure sodium lamp has exceeded 28000 hours. Compared with the service life of high pressure sodium lamp and its accessories, the actual service life of 3-4 years is no problem.
对于光源的维护,高压钠灯就容易多了,而且可以现场直接更换光源电器,成本也低。
For the maintenance of the light source, the high pressure sodium lamp is much easier, and the light source appliances can be directly replaced on site, with low cost.
5,照明配电问题,目前,LED路灯分布技术已经取得了很大的进步,一些制造商已经开发出一种辅助照明配电系统,而不是单纯依赖芯片阵列光分布,但在一个全面的视图中,光分布不能完全合理。
5. Lighting power distribution. At present, LED street lamp distribution technology has made great progress. Some manufacturers have developed an auxiliary lighting power distribution system instead of relying solely on chip array light distribution. However, in a comprehensive view, light distribution can not be fully reasonable.
6、规格没有统一的技术标准。目前LED路灯的生产还没有统一的技术标准。每个制造商都很难按照自己的标准生产自己的产品。此外,LED路灯多芯片组装的特点使得芯片与灯具捆绑在一起,不易维护。须使用原产品进行维护。
6. There is no uniform technical standard for specifications. At present, there is no unified technical standard for LED street lamp production. It's hard for every manufacturer to produce their own products according to their own standards. In addition, the characteristics of LED street lamp multi chip assembly make the chip and lamps bundled together, difficult to maintain. The original product must be used for maintenance.
由于技术标准的统一,济南发光字具有很强的通用性。不同厂家的产品可以相互配合使用。从维护的角度来看,这是非常重要的,维护是路灯管理单位的首要任务。只有这样,路灯才能及时熄灯进行养护,保证高照明率(对道路上的上级来说,同时大大降低养护成本。
Due to the unification of technical standards, Jinan luminous characters have a strong versatility. Products from different manufacturers can be used together. From the perspective of maintenance, this is very important, maintenance is the primary task of street lamp management unit. Only in this way can the street lamp be turned off in time for maintenance, so as to ensure high illumination rate (for the superior on the road, at the same time, the maintenance cost can be greatly reduced).
