When individuals select done in one solar LED street lights, they all have a problem: How long can an done in one solar LED street light last? This question could not merely answered with an local time, since all in one solar LED street light consists of 5 major components, consisting of solar panels, led lights, solar controllers, batteries, as well as light posts. How long can the all in one solar LED street lights be utilized? 5 variables choose with each other.
The life span of photovoltaic panels is greater than 25 years, as well as the life span of posts could reach more than 30 years. Get rid of so long life span can be entirely ignored for affecting the lifetime of done in one solar LED street light.
Secondly, solar energy light controllers can additionally be excluded. First, the controller is cheap, the source is convenient, repair and maintenance are convenient. Second, the controller is not easily broken. As long as the controller is made use of correctly, it will not cause much difficulty.
So we mainly have to consider the LED source of light as well as battery life, the life span of batteries approximately 5 years if correctly utilized, the supposed correct use of batteries, refers to take into consideration the battery ability for the manufacturers in the design and setup, if the daily output of the photovoltaic panel is 45Ah, after that the battery capability need to be larger than 45AH. To prevent too much discharge deepness impacts the battery's power storage capacity and also life span, the battery choosen must more than 50Ah, and also the routine suppliers will certainly select the batteries with larger capacity, but some tiny suppliers will merely pick little or just 45AH battery to minimize the price, it is suggested that clients recognize the setup before purchase.
So how long is the life span of led chips? Current top quality LED light, the light efficiency could reach 120 lm/watt, service life can up to 100,000 hrs, if you illuminate 8 hours a day, you can make use of 12,500 days, that is 34 years. This is fairly long. If we state just 100,000 hours, it would be insufficient. As a matter of fact, 100,000 hrs is 34 years, and also there is no need to bother with the durability.
Throughout the design as well as manufacture process of all in one solar LED street lights, if factories can pay even more attention to the above variables, they can much better extend the service life of all in one solar street light quotation LED street lights.
