What Determines the Brightness of Solar System Street Light?

Solar system street lights are simple to install, do not need wiring, and are green and clean, so they are widely used in beautiful rural construction projects. At present, the solar system street light market is chaotic. Many people respond that the configuration of the street light is obviously high but the brightness of the street light is not enough. Everyone buys solar system street lights for lighting purposes. What they buy is not parameters, configuration or power but light. We usually use lumens to express the brightness of solar system street lights. The nominal luminous flux of a 1W ordinary incandescent lamp is about 11-12lm, 1WLED lamp is about 150lm, and 30W solar system street light LED light source is about 4500lm. What are the main factors affecting the brightness of solar system street lights? In this article, we summarized the factors that affect the brightness of solar system street lights. After reading this article, hoping that you can purchase suitable solar system street light.

1. LED chips affect the light brightness

Many people think that the more LED lamp beads, the brighter the street light will be. This idea is wrong. LED lamp beads are mainly composed of LED chips, and the brightness of light-emitting diode chips is an important factor reflecting light efficiency (brightness). Many companies on the market use American chips with a lumen of 130lm/w. Therefore, if you want solar system street lights to have high brightness, it is best to choose high performance LED chips from big brands. Under the same configuration, the brightness of solar system street lights using big-brand chips can be increased by one-fifth.

2. Solar panels affect solar energy conversion efficiency

The energy generated by solar system street lights comes from direct sunlight. If the solar panel is blocked by green plants, it will limit the conversion of electric energy and directly cause the brightness of the solar street lamp to fail to meet the requirements. Only when the photovoltaic panel can input enough power to the battery, the battery can provide enough power to the light source, and the lamp can light up according to the set brightness; when your photovoltaic panel can't input enough power to the battery, the battery can't provide enough power to the light source. The brightness of the lamp is dimmed. If this happens, you must adjust the height of the solar system street light pole or the position of the solar panel according to the actual situation, so that the solar panel is no longer blocked and can fully absorb sunlight. The material of the solar panel is also very important. Top solar system street light manufacturers use monocrystalline silicon solar panels, which have high power conversion efficiency.

3. The height of the solar system street light pole

The height of the light pole will also affect the brightness. When choosing the height of the street light pole, the height should be determined according to the width of the road. For example, the height of the one-sided street lamp ≥ the road width, the height of the two-sided symmetrical street lamp = half the road width. The height of the double-sided zigzag street lamp is at least the width of the road 70%, so as to bring the best lighting effect. If the height of the light pole is too low, it is easy to cause a waste of resources; if the height is too high, the brightness of the solar street lamp is not enough.

4. Controller affects the brightness of the solar system street light

The control system plays a key role in the lifespan of the battery and controls the brightness of the lamps. Due to the limitation of the battery, solar lamps can't be lighted at 100% power like traditional street lamps. In continuous rainy days, the battery capacity becomes low and can't work as if it is fully charged. It needs an intelligent system to adjust the power output according to the battery capacity, so that the lamp can work under a good working condition, so as to ensure its lifespan. The controller can control the input and output according to the real-time capacity of the battery, so that the battery will not be overcharged or over-discharged, so as to protect the lifespan of the battery and make it more durable.
