Solar LED street light performance stability
Nowadays, society is vigorously advocating green environmental protection and low-carbon energy-saving life. Solar energy, as an inexhaustible and inexhaustible safe and environmentally-friendly new energy source, is gradually recognized, mastered and used by people. In order to popularize solar street lights, it is necessary to understand the stability of solar street lights and high-quality solar street lights with stable production performance.
The stability of solar street lights is mainly reflected in three aspects: Durable and normal lighting, high-quality LED light sources, and long rainy days.
Durable and normal lighting: Solar street lights absorb the amount of solar energy as energy. They charge during the day and discharge automatically at night. If there is a problem with the solar battery, the solar led lights cannot charge and discharge normally.
High-quality LED light source: It generally uses lamp bead, because LED lamp bead has many advantages, such as long lighting life, and not emitting excessive heat when used, which greatly prolongs the use of light source life.
Long rainy days: Solar street lights use solar energy to generate electricity. In the absence of sunlight, they must be able to perform lighting work normally. Solar street light manufacturers will also consider this issue when designing solar street lights. In the communication with customers, according to the local rainy weather conditions given by the customer, a suitable intelligent storage control system is configured to solve the problem that the local area can work normally during long continuous rainy days.
Improved aging test for solar led street lamp
Aging is an important guarantee of the reliability of electronic products, is a production of the last essential step. LED products can enhance the performance of aging and contribute to the late stage of the performance and stability. Solar led street lamp aging test in product quality control is a very important part, but often neglected in many cases, can not be correct and effective aging. Solar led street lamp aging test is based on the product failure rate curve of the bathtub curve characteristics and countermeasures taken, in order to improve the reliability of the product, but this method is not necessary, after all, the aging test at the expense of the life of a single LED products for the price.
Solar led street lamp aging, including the constant current aging and constant aging. The constant current source is the current constant at any time. Frequency problem, it is not constant current. It is AC or pulsating current. AC or pulse current source can be designed to be valid value is constant, but this power can not be called ¡°constant current source. Constant current aging is most consistent with the operating characteristics of the LED current is the most scientific of the LED aging; overcurrent impact of aging is also factory using the latest means of an aging through the use of adjustable frequency, current adjustable constant current source such aging in a short period of time in order to judge the quality of the led high bay life expectancy, and can pick out a lot of conventional aging can not be singled out hidden LED.
