Respirator testing method of lamps

Abstract

A respirator testing method of lamps is disclosed. The method comprises the following steps: a first respirator, a second respirator and a third respirator are selected from multiple respirators to be tested; the first respirator is placed in an incubator; thermal insulation is carried out at a first preset temperature for a first preset time, wherein the first preset temperature is higher than the temperature during normal operation of the first respirator; the first respirator is placed in an incubator; thermal insulation is carried out at a second preset temperature for a second preset time, wherein the second preset temperature is lower than the temperature during normal operation of the first respirator; high and low temperature tests are repeatedly carried out on the first respirator for preset number of times; and when the repetition number of times reaches a first preset number of times, whether edge warping or shedding phenomenon happens to the film of a respiration bolt on the first respirator is detected. By the testing method, use reliability of the respirators used on occasions with big temperature changes can be tested. The testing method can be adopted to rapidly find out design and manufacturing defects of a respirator.

Description

technical field [0001] The invention relates to a testing method, in particular to a testing method for a respirator of a lamp. Background technique [0002] With the continuous development of the industrial lighting industry, it is widely used in various industrial fields. Outdoor lighting fixtures stand the test of alternation of day and night, changing seasons, rain, dust or fog, etc. It can be seen that outdoor lighting fixtures not only need to isolate external water and dust, but also avoid pressure difference changes caused by temperature changes and fogging and condensation caused by moisture entry. Therefore, outdoor lighting fixtures need to have good sealing performance and temperature adaptability. At present, the method to ensure the sealing performance and temperature adaptability of outdoor lighting fixtures is to install a respirator on the outdoor lighting fixtures. Because the respirator has the functions of waterproof, breathable and dustproof, it can en...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the waterproof and breathable function tests of the respirator are generally carried out according to conventional conditions, without considering the influence of the actual use environment on it, and the respirator may be affected by external factors. The following problems may occur: the respirator has a long-term temperature change Use in an environment that may cause the air-permeable film of the respirator to fall off, and the waterproof failure will cause water to enter the lamp cavity, thereby damaging the electrical components or light source in the lamp cavity.
