Abstract

The invention discloses a device for detecting the luminous flux of a two-axis motion type lamp and belongs to the field of photometric detection. The technical scheme of the invention is as follows: the invention provides a device for detecting the luminous flux of a two-axis motion type lamp. The device comprises a lamp bracket, a wireless photometric probe, a polar angle motor, an azimuth car, a circular orbit, a motion controller, a monitoring computer, a left limit and a right limit, wherein the azimuth car comprises a groove-embedded roller, a gear, a connecter, an azimuth motor, and a photometric probe installation platform; the wireless photometric probe is driven by the polar angle motor to realize motion in the longitude direction, and driven by the azimuth motor to realize motion in the latitude direction; and the motion controller controls the motion positions of the polar angle motor and the azimuth motor according to instruction requirements of the monitoring computer, the wireless photometric probe returns an obtained illumination value obtained by test at each testing position back to the monitoring computer, and the monitoring computer after completing the calculation of spherical illumination integrations can accurately obtain the total luminous flux value of the lamp. The device disclosed by the invention is high in luminous flux testing accuracy, small in required darkroom space, simple in structure, convenient in maintenance and low in investment cost, accords with international standard requirements, and satisfies the needs of lamp production enterprises and third-party certification/authentication organizations in the aspect of detecting the luminous fluxes of lamps.

Description

[0001] technical field [0002] The invention relates to a device for detecting the luminous flux of a lamp, in particular to a device for detecting the luminous flux of a lamp with two-axis movement. Background technique [0003] Luminous flux is an important parameter to characterize the characteristics of a light source and an important indicator of photometry, and it is widely used in the electric light source industry and lighting engineering. Luminous flux is an important parameter to determine the energy efficiency of a light source or lamp. In the modern society of energy saving and environmental protection, the luminous flux value of LED products has become a technical barrier to international trade. Due to the temperature dependence of the light emitted by LED products, it is extremely challenging to accurately detect the luminous flux of LED lamps. Luminous flux detection methods of lamps include three methods: integrating sphere method, light intensity integrat...
