Factors affecting the quality and decay of LED solar lamps

       This is very important, the quality of LED solar lamps can be said to be a very important factor. To give some examples, the same 14mil white light segment chip is represented by LED solar lamps encapsulated with ordinary epoxy resin primer and white light adhesive and encapsulating glue. A single light in a 30-degree environment, one thousand hours later, The attenuation data is the luminous maintenance rate of 70%; if it is encapsulated with D-type low-failure glue, the light attenuation is 45% per thousand hours under the same aging environment; if it is encapsulated with the C-type low-failure glue, the same Hourly light decay is 12%; if Class B low-failure glue is encapsulated, under the same aging environment, the thousand-hour light decay is 3%; if Class A low-failure glue, under the same aging environment, the thousand-hour light decay is 6 %.

      According to the experimental results, the lower the driving current of the LED solar lamp, the smaller the heat emitted, of course, the lower the brightness. According to the survey, the design of LED solar lighting circuit, the driving current of LED is generally only 5-10mA; products with a large number of lamp beads, such as reaching more than 500, or more, the driving current is generally only 10-15mA However, the driving current of general LED application lighting is only 15-18mA, and few people design the current above 20mA.
