Abstract

The invention discloses a test method for a lamp coating. The test method for the lamp coating comprises the following steps: placing a lamp to be tested in a warm box, starting the warm box for performing a constant temperature and humidity test on the coating, and taking out the lamp from the warm box after the test is finished; placing the lamp to be tested in a cold and hot impact machine for performing a temperature impact test on the lamp, and taking out the lamp from the cold and hot impact machine after the test is finished; still standing the lamp after the constant temperature and humidity test and the temperature impact test on a test platform at normal temperature; scribing lines on the coating and exposing a metal shell of the lamp for performing a adhesive force test on the coating; under the light condition that the value of the illumination is a preset illuminance value, checking whether the coating has defects and striping phenomenon visually. The lamp with large adhesive force can be screened by adopting the method, the lamp coating falling probability can be effectively reduced after the lamp is used under a severe environment for a long time, and further the reliability of the lamp shell is improved. The basis is provided for selecting the excellent coating and an excellent coating technique for developing a product.

Description

technical field [0001] The invention relates to the lighting field, in particular to a method for testing the coating of a lamp. Background technique [0002] Coatings are thin layers of plastic applied to substrates such as metals, fabrics, plastics, etc. Coating technology is widely used in electric power, electrical machinery, electrical appliances, electronics, aviation, atomic energy, space technology and other fields. [0003] At present, the coating process is also used in the field of professional lighting. In addition to the decorative effect, it is also used to prevent the shell of the lamp from being eroded by wind, sand and rain, to maintain the insulation performance of the lamp, and to ensure the safe use of the lamp. However, after long-term application of the lamp coating, the adhesion of the coating is reduced, and the coating is prone to discoloration or peeling off, which leads to a decrease in the insulation performance of the lamp housing and cannot mee...
