Device and method for measuring light intensity parameters of special lamp

Abstract

The invention provides a device for measuring light intensity parameters of a special lamp. The device comprises a control module, a lamp projection end and a light sensing test end matched with the lamp projection end; a horizontal rotating table is arranged at the lamp projection end; the horizontal rotating table is used for fixing the to-be-measured lamp to enable the light emitting surface ofthe lamp to horizontally point to the lamp projection end; the lamp projection end is provided with a vertical light sensing target position; the light sensing test end is provided with an aiming device for enabling the light sensing target position to be aligned to the to-be-measured lamp; the distance between the lamp projection end and the light sensing test end is a test distance; the test distance enables light spots of the to-be-measured lamp to be located in the light sensing target position; a light intensity detection table capable of being vertically lifted is arranged at the lightsensing target position; when the light intensity parameters are measured, the light intensity detection table of the light sensing test end is lifted in the light sensing target position to test thelight intensity parameters of the lamp; and the horizontal rotating table rotates the to-be-measured lamp, so that light rays in different positions of the lamp can be projected to the light sensing target position for performing testing. The automatic detection of the optical parameters of the lamp can be rapidly carried out by the simple device.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a device and method for measuring light intensity parameters of special lamps. Background technique [0002] Existing lamp detection methods include online detection and manual detection: [0003] The way of online detection is to use optical sensors to realize online measurement of the optical parameters of each lamp. This method avoids the disassembly and assembly work of the lamp. [0004] Manually check the open circuit, short circuit, input power, isolation transformer and other conditions of each lamp one by one. [0005] However, online detection has the following disadvantages: [0006] (1) The system is complex and the equipment cost is high; [0007] (2) Online detection cannot control the test environment, and is easily affected by changes in natural light, power supply line voltage and current, etc. The result error is large, which cannot be used as equipment para...

Problems solved by technology

[0006] (1) The system is complex and the equipment cost is high;

[0007] (2) Online detection cannot control the test environment, and is easily affected by changes in natural light, power supply line voltage and current, etc., resulting in large errors, which cannot be used as equipment parameter calibration data, and cannot be used as a basis for comparing with national standards to determine whether it is up to standard

[0009] (1) Manual can only judge whether the lamp is on or off, and the naked eye cannot distinguish the difference in the brightness of the lamp under high brightness conditions, and manual long-term high-intensity work is prone to misjudgment;

[0010] (2) Manual inspection is time-consuming and laborious
