Abstract

The invention discloses an on-line real-time detection device of optical parameters, color parameters and electrical parameters of a light emitting diode (LED) lamp. The device comprises a total lumen test part, an optical fiber spectrograph, a digital power meter, a computer, a test starting switch, a barcode printer matched with the computer, and mechanical parts, wherein the total lumen test part, the optical fiber spectrograph and the digital power meter are all connected with the computer through universal serial buses (USBs); the test starting switch is connected with the computer through a serial port; and the total lumen test part comprises a large-area solar battery, a luminosity function matching optical filter and a polytetrafluoroethylene diffuse transmission film. The on-line real-time detection device has the largest advantage that the large-area solar battery is adopted as the total lumen measuring part of the LED lamp, so the measuring device has the advantages of simple optical structure, simple and convenient manufacturing process, low cost and high practicality, can be applied to on-line detection of industrial production, can also be used as off-line detection equipment in a laboratory, and has wide popularization and application value.

Description

technical field [0001] The invention relates to a detection device for LED lamps, in particular to an online real-time detection device for parameters of total lumen output, color rendering index, color temperature and lamp lumen efficiency of LED lamps. Background technique [0002] The total lumen output, color rendering index, color temperature and lumen efficiency of LED lamps are the basic light, color and electrical parameters of LED lamps. Among them, the lumen efficiency parameter is an important index to evaluate the actual energy saving of LED lamps. The key to this parameter test is to test the total luminous flux of the lamps. [0003] The most commonly used method for testing the total luminous flux output by existing light sources is to use a spherical photometer composed of an integrating sphere, but it is not suitable for testing lamps; The principle is to derive the total luminous flux data output by the lamp through the space integral calculation through t...
