The invention belongs to the lamp test technical field and provides a lamp impact test device and a test method. The lamp impact test device comprises a base, a guide support, an impact table and an impact box. A communicating device is arranged on the base fixedly, wherein the communicating device comprises a communicating pipe, a first piston and a second piston, wherein the first piston and the second piston are arranged at two ends of the communicating pipe in a vertical and sliding mode. The guide support is vertically arranged and the lower end of the guide support is fixedly connected on the base. The impact table is arranged on the guide support in a sliding mode and fixedly connected with the first piston. A balancing weight is arranged on the second piston. The impact box is arranged on the guide support in a sliding mode. A power component is arranged at the upper end of the guide support. The lamp impact test method is conducted by means of the lamp impact test device. According to the lamp impact test device and the test method, a condition that a wave pattern of impact force borne by a lamp is a sine wave is imitated well and whether the intensity of a lamp installation support and the intensity of a lamp internal structural part meet actual usage requirements or not can be evaluated rapidly and accurately.
Description
technical field [0001] The invention belongs to the technical field of lamp testing, and in particular relates to a lamp impact testing device and a testing method. Background technique [0002] As an essential electrical appliance, lamps are widely used in various occasions. At present, a large number of lamps have been installed on mobile carriers (such as locomotives), and the lamps will be subjected to various sudden low-frequency and large-amplitude impacts (such as collisions in the locomotive workshop, emergency braking, etc.), and these impacts have a great impact on the installation position and internal structure of the lamps. A serious threat that may cause damage to the luminaire. Therefore, in the research and development process of lamps, the strength of the installation position of lamps and the strength of internal structural parts are technical parameters that must be investigated. It is very important to simulate the low-frequency and large-amplitude impa...
