How to Clean Solar Panels On Outdoor Garden Lights?

    Outdoor Solar Garden lights are becoming increasingly popular due to their low cost, easy operation, energy conservation, and environmental friendliness.   Due to their frequent exposure outdoors and exposure to wind and rain, there is usually a lot of dust or sediment on the solar lawn lights or solar wall lights, and solar post lamps. This dust or sediment can inhibit the performance of light, reduce photoelectric conversion, and affect lighting.     Therefore, we must regularly clean outdoor garden solar lights, To keep the lamppost clean as new.   How do you clean solar garden lights?   Here is a good and fast method to clean without buying cleaning agents or sanding, without any loss,  Use a damp cloth or sponge with toothpaste to wipe the solar panel.   Some people use sandpaper, which can cause wear and tear, we are not suggested.   1. Wet the surface of the lamp with a cloth or sponge,    2.  Squeeze a little toothpaste onto it Scrub the solar panel,  when wiping, be sure to wipe in one direction with moderate force. For fragile components, use gentle and gentle action without excessive force until all dirt is removed. Sponge, please do not use a rough side. This may scratch the panel. 3. Then wash down the foam on the solar panel with water,     4 Finally take a clean cloth or towel and wet it with water. You can see that the solar panels are as clean as new. It's that simple.   Of course, you need to ensure that the water is kept away from the internal electronic devices of light. Concentrate water on the panel itself and do not let electronic devices on the surface get wet Clean the interior of solar lamps.     If you want to clean the interior of lighting fixtures, special attention should be paid to turning off the power first and then wiping. This will be safer. Please also be careful not to tighten the bulb too tightly clockwise, otherwise, it may come off due to being too tight.

What’s the integrating sphere testing , -- how we testing solar lights

  Every solar lamp we produce in the production line usually undergoes integrating sphere testing in our factory testing room. What is the integrating sphere test?   The integrating sphere is a hollow sphere whose outer shell is usually made of metal, the interior is coated with diffuse reflective material, and the shell wall has two or several light holes.  The light is collected by the integrating sphere through the sampling port, and is scattered very evenly inside the integrating sphere after multiple reflections. When using an integrating sphere to measure luminous flux, the measurement results can be made more reliable. The integrating sphere can reduce and eliminate measurement errors caused by the shape of the light, the divergence angle, and the difference in responsivity at different locations on the detector.   What are the test parameters of the integrating sphere test? Integrating sphere test mainly measures the electrical parameters of LED lamps, lamp beads or light sources: and light parameters and color parameters.     Electrical parameters: voltage, frequency, current, power, power factor, Light parameters: luminous flux, light efficiency; Color parameters: Color temperature (CCT) CRI (Ra,R9), color coordinates,     1 Correlated color temperature is represented by the absolute temperature "K". When the color of the light emitted by the light source is the same as the color radiated by the black body at a certain temperature, the temperature of the black body is called the color temperature of the light source (lamp). Different light source color temperatures have different visual effects, as shown in the following table     2 Dominant wavelength: A sample color is obtained by mixing a certain spectral color with a certain standard illuminant in a certain proportion. The wavelength of this spectral color is the dominant wavelength of the sample color. 3. Luminous flux color ratio: RGB refers to red, green and blue, and the numerical value refers to the ratio of these three colors in the light source. 4. Peak wavelength: Usually the beam of light we see is not just a single wavelength of light, it is a combination of light of many wavelengths, and the light with the largest wavelength energy is the peak wavelength of the beam of light. 5. Color purity: Monochromatic light is the color with the highest color purity. The more white light penetrates into it, the lower the color purity. 6. Color rendering index: This value indicates how well the light source presents the true color of the object. The closer it is to 100, the better the display effect of the lamp. Generally speaking, if the value is >80, the quality can be considered excellent. The value on the test report is 86.9, indicating that the color rendering effect of this lamp is excellent.   7. Luminous flux: The lumen (lm) of the lamp refers to the total energy emitted by the light source and received by the human eye. 8. Light efficiency: that is, the luminous flux emitted by the lamp per watt. (Lm/watt) 9. Optical radiation power: the radiation energy (W) of all wavelength components emitted per unit time.   What's Integrating Spheres Testing Mothod?    Integrating spheres are also divided into many specifications. Commonly used ones are 0.3M, 1.5M, 2.0M, 2.5M and 3M. How to test? The following are the test steps.     1. Prepare. Prepare an integrating sphere of appropriate size, a standard light source with a luminous flux close to the light source of the lamp, an ambient temperature of about 25 degrees, and avoid wind blowing into the integrating sphere; 2. Check. Install the standard light source into the integrating sphere, connect the current source and power meter, and then light the standard light source. Adjust the integrating sphere software operation interface to continuous testing until the luminous flux reaches stability and record the luminous flux value; 3. Calibration. The calibration operation is similar to the inspection, except that zero calibration is required before lighting the standard light source. After the luminous flux reaches stability, enter the standard color temperature and standard luminous flux of the standard light source in the integrating sphere software operation interface, and then click to start calibration. The integrating sphere tester will automatically complete the calibration; 4. Test samples. Install the sample into the integrating sphere, light the sample, close the integrating sphere, and start testing. After the luminous flux stabilizes, record the value.       a) After the electrical wiring is connected, install a light in the integrating sphere and perform system calibration before the first test.   Calibration (operated on the software): Select a standard lamp with a luminous flux similar to that of the sample for calibration. After the luminous flux emitted by the standard lamp reaches stability, start the test.     b) Select automatic integration time, directional emitting LED lamps, select integrating sphere 2 test methods, select non-directional emitting LED lamps 4 methods: Set the test integrating sphere selection and power supply mode selection. When testing the entire lamp with a large integrating sphere, you only need to set these two items as the large sphere/entire lamp LED and select external power supply as the power supply method.     Then click Settings and then the Output Power Supply button. 4. Click the test button. After a period of time, wait for the output to stabilize, then click the stop button. Sample inspection When installing a fluorescent tube in the center of the integrating sphere, the center of the sample should ensure that the center of the sample is consistent with the center of the sphere. Light up the sample, close the integrating sphere and start testing under the specified sample declaration conditions. Read the value after the luminous flux emitted by the sample stabilizes.     5 Save the Chinese version of the integrating sphere test source file to the specified folder, the file suffix format is. hpl.     The working principle of Integrating Spheres    The working principle of the integrating sphere is that the light emitted by the light source is processed by the condenser and the diaphragm and becomes parallel light and enters the interior of the integrating sphere through the light entrance of the integrating sphere. The light entering the integrating sphere will undergo multiple diffuse reflections inside the integrating sphere and finally be The light outlet emits uniformly. By detecting the luminous flux of the light outlet, and then converting it according to the formula, data such as reflectivity and transmittance can be obtained. Integrating spheres

What are the Top 5 Key Factors to Consider When Choosing Solar Wall Mount Lights

 What are the Top 5 Key Factors to Consider When Choosing Solar Wall Mount Lights?   Solar wall mount lights are an excellent addition to any outdoor space, combining functionality with sustainability. As a factory specializing in solar garden lights, we understand the importance of choosing the right lighting solutions for your home or business. Solar wall mount lights offer a great way to illuminate outdoor areas like patios, gardens, driveways, and pathways, all while being eco-friendly and cost-efficient.   In this article, we will outline the top 5 key factors you should consider when selecting solar wall mount lights. By focusing on these aspects, you can ensure you’re investing in lights that provide the best performance and longevity.       1. Solar Panel Quality and Efficiency   The most critical factor in determining the performance of solar wall mount lights is the quality and efficiency of the solar panel. The solar panel is responsible for converting sunlight into energy, so the more efficient it is, the more energy your lights can store and use.   1) Types of Solar Panels - Monocrystalline Panels : These are the most efficient type of solar panels, known for their high energy conversion rates and ability to perform well in both direct and low sunlight conditions. While they are typically more expensive, they provide long-term energy efficiency, which is worth the investment. - a Polycrystalline Panels : Slightly less efficient than monocrystalline, polycrystalline panels are still a good choice for those who want reliable performance at a lower cost. However, they may not perform as well in low light conditions, such as cloudy days. - b Amorphous Panels : These panels are the least efficient but are also the most affordable. They work best in overcast conditions but may not store enough energy for long hours of illumination.   Key Tip : Look for solar wall mount lights with high-efficiency monocrystalline panels for optimal performance, especially if you live in an area with limited sunlight.   ---   2. Battery Capacity and Run Time   The battery in solar wall mount lights stores the energy collected by the solar panel. Battery capacity, measured in milliampere-hours (mAh), determines how long the lights can stay illuminated at night. When choosing solar wall mount lights, it’s essential to ensure the battery capacity aligns with your lighting needs.   Types of Batteries - Lithium-ion (Li-ion) Batteries : These are the most common type used in solar lights. They offer higher capacity and longer run time compared to other batteries, making them ideal for locations that require longer illumination. - Nickel-Metal Hydride (NiMH) Batteries : NiMH batteries are an eco-friendly alternative but may not hold as much charge as lithium-ion batteries. They are, however, more environmentally friendly and safer for disposal.   Key Tip : Opt for solar wall mount lights with batteries that have at least 2000 mAh capacity for longer-lasting light, especially in areas where you need illumination throughout the night.   ---   3. Brightness and Light Output (Lumen Rating)   When selecting solar wall mount lights, brightness is a crucial consideration. The brightness of a light is measured in lumens, and the appropriate lumen rating will depend on the purpose of the light.   Different Lumen Levels - Low Brightness (50-100 lumens) : Ideal for soft, decorative lighting around patios, garden walls, or fences. - Medium Brightness (100-300 lumens) : Suitable for illuminating pathways, entrances, or general outdoor spaces where moderate light is needed. - High Brightness (300+ lumens) : Best for security purposes or for areas requiring strong, bright light, such as driveways, garages, or commercial buildings.   Key Tip : For general outdoor lighting, a medium lumen range (100-300 lumens) should suffice. If you're looking for security lighting, go for higher lumens (300+).   ---   4. Weather Resistance and Durability   Since solar wall mount lights are exposed to various outdoor elements, they need to be durable and weather-resistant to withstand rain, snow, wind, and extreme temperatures. The durability of the light is typically indicated by the IP (Ingress Protection) rating, which measures its resistance to dust and water.   IP Rating Breakdown - IP65 and Above : This rating means the lights are fully protected from dust and can withstand water jets from any direction, making them suitable for heavy rain and outdoor use. - IP44 : Suitable for areas with light rain or where the lights are somewhat sheltered.   Materials also play a role in determining the durability of solar wall mount lights. Opt for high-quality materials like stainless steel, aluminum, or weather-resistant ABS plastic for longer-lasting performance.   Key Tip : Choose solar wall mount lights with an IP65 rating or higher if you live in an area prone to heavy rain or snow. For more mild climates, an IP44 rating may be sufficient.   ---   5. Motion Sensor and Smart Features   One of the most convenient features of modern solar wall mount lights is the incorporation of motion sensors and smart technology. Lights with motion sensors automatically turn on when they detect movement, providing both security and energy efficiency.   Motion Sensor Types and Features - Passive Infrared (PIR) Sensors : These sensors detect heat from moving objects, such as people or animals. They are commonly used for security lighting and can save energy by only turning on when needed. - Range and Sensitivity : Consider the range and sensitivity of the motion sensor. A wider detection range is better for larger spaces, while a more sensitive sensor is ideal for areas with high traffic. - Dimmable and Timer Settings : Some solar lights come with dimmable settings, allowing you to adjust the brightness. Others feature timers, so you can set the lights to turn off or on at specific times.   Key Tip : For pathways and entrances, opt for lights with motion sensors to enhance security and save energy. Ensure the range and sensitivity of the motion sensor match your needs.   ---   Bonus Factor: Aesthetic Appeal   While functionality is essential, aesthetic appeal should not be overlooked when choosing solar wall mount lights. These lights should complement the design of your outdoor space, whether it's modern, traditional, or rustic.   Design Styles - Modern Designs : Clean lines and minimalist designs are perfect for contemporary homes or gardens. - Traditional Designs : Lantern-style or antique-looking fixtures add a classic touch to your outdoor area. - Decorative : Some solar wall mount lights come with intricate patterns or color options, serving both as a light source and a decorative piece.   Key Tip : Choose a design that blends seamlessly with your home’s exterior or garden decor. Functional lights don’t have to compromise on style!   ---   Conclusion   When choosing solar wall mount lights for your outdoor space, considering the key factors of solar panel efficiency, battery capacity, brightness, durability, and motion sensors will help you make the best choice. By prioritizing these aspects, you can invest in lights that will enhance the safety, functionality, and beauty of your outdoor areas while enjoying the benefits of solar energy.   At our factory, we specialize in creating high-quality solar garden lights that meet these essential criteria.
