Embodiment Construction

[0024] The steps of the inventive method are:

[0025] Step (1) Carry out a constant thermal stress accelerated life test on electronic energy-saving lamps under high temperature stress conditions. The high temperature stress level is 50°C to 70°C. The specific steps of the constant thermal stress accelerated life test are:

[0026] a. Randomly select 20 products from a batch of off-line electronic energy-saving lamp products, and divide them into two groups, with 10 products in each group;

[0027] b. Place the selected two groups of electronic energy-saving lamp products as test samples in two temperature test chambers with set temperatures. The ambient temperatures of the two temperature test chambers are set to 50°C and 70°C respectively. Keep the temperature test chamber relatively closed so that there is no convective air in the temperature test chamber;

[0028] c. Use the power supply control equipment to control the power supply voltage of the test samples in the two...

Abstract

The invention relates to an electronic energy-saving lamp service life rapid detection method. The existing detection method is long in period and low in efficiency. The method of the invention includes that firstly two groups of electronic energy-saving lamps are placed under high temperature stress condition and subject to constant heat stress accelerated life test, so as to obtain the tested life value; and then the service life of test sample under normal temperature condition is calculated by combining arrhenius model according to the tested life value of the test sample under high temperature stress condition. The invention greatly shortens test and detection time, saves energy source and other experimentation cost and has higher life calculation evaluation accuracy.

Description

technical field [0001] The invention relates to a quick detection method for the service life of an electronic energy-saving lamp, belonging to the technical field of detection. Background technique: [0002] Electronic energy-saving lamps are known as the third-generation new light source for their excellent performance of high luminous efficiency, power saving, environmental protection and long life, because they have excellent performances of high luminous efficiency, power saving, environmental protection and long life. my country is a big producer and exporter of electronic energy-saving lamps, and it is also the largest production and export base of electronic energy-saving lamps in the world. However, the quality of electronic energy-saving lamps for many small and medium-sized enterprises is not optimistic. Today, with the increasing awareness of energy saving, environmental protection and quality, to ensure the quality of electronic energy-saving lamps, it is necess...
