PAR lamp fixed focus detection device and fixed focus detection method thereof

Abstract

The invention provides a PAR lamp fixed focus detection device and a fixed focus detection method thereof. The device comprises a test power supply, an illumination meter, a test tube, a tripod, a frame, a vacuum pipeline, a vacuum test chamber, a vacuum pump and a vacuum meter. The vacuum pump is arranged and fixed in the frame. The vacuum test chamber is connected with the vacuum pump through the vacuum pipeline. The vacuum meter is connected with the vacuum pipeline. The tripod is located on the front end of the vacuum test chamber. The test tube is fixedly arranged at the top of the tripod. A photosensitive probe body is located in the test tube. The test power supply and the illumination meter are placed on the frame. The illumination meter is connected with the photosensitive probe. The test power supply is connected with the vacuum test chamber. According to the invention, fixed focus quality real-time detection is carried out; a detected unqualified fixed focus product can be reworked; and the problem that the unqualified fixed focus product cannot be reworked but scrapped due to the fact that a follow-up process is completed in a traditional process is effectively avoided.

Description

technical field [0001] The invention belongs to the field of lighting sources, and in particular relates to a method aimed at improving the qualified rate of the focusing process of PAR lamps. Background technique [0002] As a large-scale lighting source, PAR lights are widely used in strong lighting fields such as airports, squares, stages, airborne, and shipborne. The central light intensity of a PAR lamp is its most important technical indicator. In the production process, the key process to determine the central light intensity is the focusing process, which is the process of fixing the wick at the focal point of the reflector. [0003] The traditional fixed-focus process uses tooling to limit the relative position of the wick and the reflector. The tooling is processed based on the theoretical design value of the focus of the reflector parabolic curve. In practical applications, there are the following problems: First, the actual reflector After polishing and...
