In recent years, with the country's strong support for environmental protection industry, the solar street light industry is developing faster and faster, along with the development of more and more solar street light products on the market, but more and more problems are derived, such as uneven illumination, unreasonable light distribution, etc.. In fact, a good solar street light also has its own set of criteria for judging, as follows.
Performance indicators: two high, two low, three long
High luminous efficiency: high brightness at the same time, power consumption can not be high, so the light source must be high light efficiency, this specific value is increased according to the LED luminous efficiency. At present, the overall luminous efficacy of 160lm/W or more is considered relatively high, so in this year we set him at 160lm/W.
High charging and discharging efficiency: The high charging efficiency of the system is a strong guarantee of the power used by the light source. High charging and discharging efficiency is not only a test of the solar controller (constant current integrated machine), but also a test of the solar panel, light source and the controller (constant current integrated machine) with the degree of cooperation.
Low cost: to achieve perfection can not just consider the high configuration, must be taken cost-effective, high performance while controlling the cost, so that this set of solar street light selling price in the market price ± 10% or less.
Low installation difficulty: the perfect solar street light must be user-friendly, so this set of lights to be very simple to install, at the beginning of the design will be easy to avoid the installer's mistakes, even raw hands can also follow the installation manual to easily and quickly complete the installation.
Long pole distance: Given that solar street lights are mainly for the rural township road lighting market, these markets have a small traffic flow, slightly lower requirements, and the total project budget is not high, so the spacing between the poles is usually done relatively large, the national standard requirements of 3 to 3.5 times the height of the light source is certainly not met. The specific index we give is: the pole distance is 5 times the height of the light pole, no obvious dark areas.
Long cloudy and rainy day support: The significance of street lights for the fluidity and safety of road commuting is self-evident. So whether it is sunny or rainy, the pedestrian demand for street lights to work every day is constant, and it becomes a hard indicator for solar street lights to be on every day for 365 days.
Long life: With the development of lithium batteries, the service life of the whole set of solar street lights is no longer limited by the short life of 2-5 years of lead-acid batteries, the quality of lithium batteries is able to extend the life of the whole light to more than 10 years. Therefore, taking into account the long-term use of lights and maintenance costs, the whole system of 10 years of life is also the perfect solar street light has some hard indicators.
The above criteria for solar street lights are shared here, solar street lights have the advantages of good stability, long life, high luminous efficiency, easy installation and maintenance, high safety performance, energy saving and environmental protection, economic and practical. It can be widely used in urban main and secondary roads, neighborhoods, factories, tourist attractions, parking lots and other places.
