The invention discloses a high and low temperature testing device for lamps, which comprises: an incubator, an intermediate partition for dividing the space in the incubator into a first cavity and a second cavity, a lamp mounting seat for installing lamps, and a device for generating high-temperature steam. High-temperature steam engine, liquid nitrogen tank for storing low-temperature nitrogen, high-temperature air guide tube, low-temperature air guide tube, high-temperature air extractor for extracting gas in the first chamber, low-temperature air extractor for extracting gas in the second chamber, activities Hermetic doors, racks, gears, servo motors, a first pusher for moving the lamp mount from the first chamber to the second chamber and a second pusher for pushing the lamp mount from the second chamber to the first chamber; high temperature The air guide pipe is connected with the high-temperature steam engine and the first chamber; the low-temperature air guide pipe is connected with the liquid nitrogen tank and the second chamber; the high-temperature air pump is connected with the first chamber; the low-temperature air pump is connected with the second chamber. The invention is beneficial in that it can simulate switching of lamps and lanterns under high-temperature and low-temperature working environments.
Description
technical field [0001] The invention relates to a high and low temperature testing device for lamps. Background technique [0002] China has a distinct climate throughout the year. In the cold winter, the manufacturing materials of lighting fixtures used outdoors will be affected by the low temperature, the texture will become hard and easy to break; in the hot summer, the outdoor lighting fixtures will be affected by the high temperature, and some manufacturing materials will be Heat deformation, lower hardness. In particular, lighting fixtures used on moving objects are easily damaged when a high-temperature environment enters a low-temperature environment or enters a high-temperature environment from a low-temperature environment. [0003] Therefore, the stability of the lamps and lanterns in high and low temperature environments should be tested before they leave the factory. Contents of the invention [0004] In order to solve the deficiencies of the prior art, the...
