Abstract

The invention discloses a test method for the luminous flux of LED light strings. The test method comprises the following steps that 1) test samples are classified according to the light source structure of the light strings, the light strings whose light sources are separated independent units are first type of light strings, and the light strings in which LEDs are assembled on a flexible circuit board or a PCB hard board are second type of light strings; 2) that change of the luminous flux is lower than 0.5% in 30 minutes is set as the stable test condition for the LED light strings, and test is carried out after the condition is satisfied; and 3) for the first type of light strings, light sources of the LED light strings include LED lamps or LED modules connected to a lead in series or parallel, and an integrating sphere system tests the luminous flux of the single LED lamp or module independently; and for the second type of light strings, the test samples are selected in a sample pretreatment method, and a tool is selected for luminous flux test according to the light emitting type. Thus, the luminous flux of the LED light strings can be effectively tested to evaluate the energy efficiency, the operability is high, and the test method is high in evaluation accuracy and repeatability.

Description

technical field [0001] The invention relates to the field of performance testing of LED lamp strings, in particular to a method for testing the luminous flux of LED lamp strings. Background technique [0002] With the development of solid-state lighting technology, LEDs have rapidly improved in technology and performance, can provide the same or higher quality lighting effects, and are more energy-efficient than traditional lighting fixtures, making them widely used in indoor and outdoor general lighting, decorative lighting, and landscape lighting. Lighting and other fields are more widely used. In the current market, due to the advantages of energy saving, long life, and less heat generated by LED light sources, light strings using LED light sources have gradually replaced traditional light source light strings and become the main product in the light string market, and LED light strings The use is not only used for decoration and landscape lighting, but its scope of appl...
