What is the difference in lighting effect between split solar street lamps with the same power lens and ordinary flat street lamp heads?
If you are comparing solar street light projects, you are likely to encounter two mainstream lamp heads: the lens type split solar street light, and the most common flat road lamp head on the market.
On the surface, the two have the same power, but there is a price difference. Many engineering procurement and contractors may wonder: is it worth spending more budget on lens payments? Today, let's set aside the rigid parameter rhetoric and truly break down the difference between the two.
1. Lighting effect: With the same wattage, there is a significant difference in road brightness
The ordinary flat road lamp head belongs to wide-angle floodlight output, and the light will spread out in all directions.
Part of the light is wasted in the air and roadside green belts, resulting in less effective light projected onto the asphalt pavement. The road surface often appears bright in the middle and dark on both sides, with uneven light spots.
The lens type street lamp comes with a secondary optical lens, which can redistribute the direction of light. The light is precisely directed towards the road surface, with a longer illumination distance and more uniform illumination throughout the entire road.
Under the same 60W and 70W power, the actual lighting effect of the lens model on the road surface is much better than that of ordinary flat lamp heads. **
Driving by at night, the entire road is bright and smooth, not one bright and one dark.
2. The installation spacing is larger, which directly saves a large amount of engineering costs
Ordinary flat solar street lights can only be installed 18-19 meters apart during road construction.
If you want the entire road to be illuminated without dark areas, you must purchase more street lamps. As the number of lamps increases, the cost of materials, poles, and labor construction also increases.
The lens split street lamp has a wider coverage range, with a 60W model lamp spacing of 20-22 meters and a 70W version installation spacing of 22-24 meters.
The total number of lighting fixtures you need to purchase decreases on the same length of road. Whether it's urban main roads, rural roads, or suburban road projects, wide spacing installation can significantly reduce your overall project budget.

3. Low glare design, safer for pedestrians driving at night
Ordinary flat lamp heads emit light at large angles, which can easily pierce the eyes of drivers and pedestrians, causing glare. When driving at night and encountering glare, it is easy to temporarily lose sight of the road conditions, which poses a safety hazard.
The optimized lens optical path directs the light downwards towards the road surface, reducing the overflow of stray light upwards and sideways. The lighting environment is soft and uniform, with low glare, making it more driver friendly and suitable for roads with heavy traffic such as municipal main roads and highways.
4. Split structure, charging efficiency and easier maintenance in the later stage
The lens model adopts a split design, with the solar panel and lamp head independent of each other.
Solar photovoltaic panels can rotate and adjust their orientation independently, accurately aligning with the direction of the sun without being limited by the angle of the lamp arm or lamp head. It can capture the most sunlight throughout the year, resulting in higher charging efficiency.
The battery compartment can be placed under the lamp post, away from the heat generated by the LED lights. The working temperature of the battery is lower, and the service life of lithium batteries can be significantly extended. When replacing the battery in the later stage, the staff can directly open the battery compartment on the ground for maintenance, without the need for high-altitude work to remove the entire lamp head, saving time and effort in maintenance.
5. Endurance and shell protection, suitable for rainy and high-temperature outdoor environments
The lens split street lamp can be optionally equipped with 3.2V 60Ah/80Ah high-capacity lithium batteries. Adequate energy storage can ensure that the lights stay on all night even in long-term continuous rainy days, making it very suitable for rainy areas such as Africa and Southeast Asia.
The lamp head shell is made of die cast aluminum alloy material, and the hollow heat dissipation groove has excellent heat dissipation performance, taking away the heat generated by LED operation, delaying light attenuation, and prolonging the service life of the lamp. IP65 waterproof and dustproof grade, stable operation in rainstorm, humid and high-temperature tropical outdoor environment.
The light source uses original Philips 5050 LED beads, with stable brightness output and color temperature adjustable from 2700K to 6500K. Warm light, neutral light, or cool white light can be selected according to the needs of road projects.
