Let us briefly understand some basic optical parameters.
Luminous flux: For a lamp, the simplest explanation is how much light it emits, in lumens (LM). This is very important. Simply put, luminous flux is an important criterion for judging whether the solar floodlight is bright enough.
Luminous efficiency: The luminous efficiency of a lamp is the amount of light that can be emitted per unit power, in LM/W. The higher the light efficiency, the more light and brighter the solar flood light with the same power will emit.
Color temperature, light source color temperature is different, light color is also different. Low color temperature light is yellowish, we call it warm color, yellow light has good fog permeability; high color temperature light is white, high color temperature white light used for road lighting has intermediate visual effect, good visibility, and better than low color temperature yellow light Brighter.
So how to choose the light source?
Understand the relevant knowledge, we need to know how to choose the light source, the following is a high-power LED light source for your reference.
Efficient use of light, the use of solar floodlights with patented lenses improves light utilization.
The integrated design, the integrated design makes the LED directly and closely connected to the housing, and heat dissipation through the heat dissipation wing of the housing and the air convection, which fully guarantees the service life of the LED flood light.
Using street lights with uniform light distribution can solve the problems of concentrated beams and obvious dark spots, so that the irradiation area is larger and the illumination is more uniform.
No glare, no flicker. Eliminate the glare, visual fatigue and line of sight interference caused by the bad glare of ordinary street lamps, and improve the safety of pedestrians;
4. Figure Out The Lighting Time of Solar Flood Light
A solar flood light is best to light up all night. At present, many solar flood lights on the market don¡¯t have enough lighting time, and some can only light up for three or four hours. So be sure to understand the constant brightness of the solar flood light. How long can the light be on?
5. Choose Whether to Add A Human PIR Sensor
Solar flood light with human sensor is to save battery energy to extend the lighting time. Generally, when there is no one, the brightness of solar flood light is 5%-20% of full brightness. Please choose whether to bring a human sensor according to your needs.
6. Choose Quick Installation Solar Flood Light
Solar floodlights are divided into wall installation and pole installation. Please choose which installation method of the lamp according to the actual use.
7. Choose IP65 and Anti-Corrosion Solar Flood Light
Solar floodlights are outdoor lighting fixtures that are exposed to bad weather all year round. As a result, the surface of the solar flood lamp is easily corroded, on the one hand, it will be unsightly, and on the other hand, it will cause the life of the floodlight to decrease. Powder electrostatic spraying means that the powder is negatively charged. Under the action of electrostatic force and compressed air, the powder is uniformly adsorbed on the workpiece. This method can make the surface of the lamp more uniform and smooth.
8. Select A Easy Maintenance Solar Flood Light
Normally, solar flood lights are maintenance-free. However, the actual situation inevitably encounters the situation of not turning on the lights, and maintenance and replacement are needed at this time. An easy-to-maintain floodlight can greatly reduce costs and time.
9. Select a Longer Service Fife and Warranty Period Solar Flood Light
Generally speaking, the lifetime of solar light transmission is 3-5 years, and the supplier¡¯s warranty is basically 2-3 years. So be sure to choose a supplier with a long warranty period.
10. Select Suppliers With Good After-Sales Service
After encountering problems, maintenance and replacement costs may be high. During the warranty period, the supplier is obliged to maintain and replace products with quality problems. So choose a supplier with good after-sales service.
