Abstract

The invention discloses a self-adaptive on-off LED service life test system and method based on vehicle arrival. The system specifically comprises a lamp control device, an acceleration environment device and a lamp performance test device, wherein the lamp control device comprises a programmable power supply, an upper computer, a programmable relay and a stabilized voltage supply, the acceleration environment device is internally provided with a group of control group test lamps which are connected with a voltage-stabilized power supply to keep normal lighting, and two groups of experiment group test lamps are respectively connected with a programmable power supply and a programmable relay; according to the system test method, through dimming control of a programmable power supply and on-off control of a programmable relay, actual road working conditions of LED lamps applied to an adaptive on-off system are simulated, optical performance data of the lamps of an experimental group in a continuous unstable working state are collected and compared with those of the lamps of a control group, the system can accurately predict the service life of the road LED lighting lamp suitable for self-adaptive opening and closing, and provides a reference basis for actual engineering.

Description

technical field [0001] The invention belongs to the technical field of life testing of LED lamps, and in particular relates to a self-adaptive switching LED life testing system and method based on vehicle arrival. Background technique [0002] Compared with traditional fluorescent lamps and energy-saving lamps, LED lamps have the characteristics of outstanding high brightness, low energy consumption, and long life, and have become the most commonly used new-generation mainstream light sources in people's daily work and life. With the rapid development of my country's road traffic construction, the construction scale and quantity of road tunnels are also increasing, and tunnel lighting has also emerged problems such as energy saving and safety that need to be solved. With the maturity of LED light source technology, it has been More and more road tunnels are beginning to use LED lamps to provide better lighting effects. [0003] Due to the scarcity of traffic in mountainous r...
