    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.      

  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
