Description

Technical Field

[0001] The invention relates to the technical field of detection and certification, and in particular to a fully automatic lamp life testing device. Background Art

[0002] Lamps, or lighting fixtures, are essential consumables in modern daily life. With the progress of my country's economy and society, the emergence of new light sources such as fluorescent lamps, energy-saving lamps, and LEDs has led to a revolutionary evolution in lighting fixtures. Lamps need to indicate their service life before leaving the factory. In order to check whether the batch of lamps is qualified, they need to be inspected, that is, a number of lamps are randomly selected from the same batch to test their service life and the number of switches. At present, there is no report on a public detection device that can quickly achieve the above test purpose. Summary of the invention

[0003] The purpose of the present invention is to provide an efficient and fully automatic lamp life testing device in order to overcome the defects of the above-mentioned prior art.

[0004] The purpose of the present invention can be achieved by the following technical scheme: a fully automatic lamp life test device, the device includes a bracket, a plurality of lamp holders detachably mounted horizontally on the bracket, and a controller for controlling the power on and off of the lamp holders, the lamp holders are provided with a plurality of lamp holders arranged in parallel, one end of the lamp holder is provided with a socket and is matched with a live plug. During the test, a number of lamps are randomly selected from the same batch, installed on the lamp holders of the lamp holders, and then the lamp holders are installed on the bracket, the plug is inserted into the socket of the lamp holder to power on, and then the power on and off of the lamps are controlled by the controller, and then the quality of the lamps is observed to determine whether the batch of lamps is qualified. Since the power on and off is automatically controlled by the controller, on the one hand, it is more automated, and on the other hand, more items can be tested, such as power on for 30s and power off for 30s, so as to determine the number of times the batch of lamps can be turned on and off; for example, power on and off once after 20 hours, the average life of the batch of lamps can be determined.

[0005] The two vertical columns of the bracket are provided with a plurality of bosses opposite to each other, each boss is provided with a groove matching the bottom surface of the two ends of the lamp holder, and one of the bosses connected to the two ends of the lamp holder is provided with a cover for fixing the lamp holder. This arrangement facilitates the loading and unloading of the lamp holder, and since the lamps are large and small, when the size of the lamp exceeds the distance between two adjacent bosses on the same vertical column, one of the lamp holders can be removed, so the device can be applied to lamps of different specifications.

[0006] The cover is in an inverted U shape, with one side of the cover being rotatably connected to the boss through a rotating shaft, and the other side being provided with a screw hole and connected to the boss through a bolt, and the shape of the inner wall of the cover matches the shape of the upper part of the lamp holder. Due to different occasions of use of lamps, some lamps are set downward, some are set upward, and even some are set horizontally, so the two ends of the lamp holder of the device are set into a cylindrical shape, and then the lamp holder is rotated to adjust the direction of the lamp holder, and then the cover is covered, and the bolts are tightened to clamp the lamp holder, so this setting can improve the accuracy of the test.

[0007] Each vertical column is equipped with 5 to 10 bosses, which can test multiple batches of lamps at the same time, greatly improving the testing efficiency.

[0008] Each of the lamp holder poles is provided with 15 to 25 lamp holders, thereby further improving the test efficiency.

[0009] Each lamp holder on the lamp holder rod is provided with a current sensor for sensing the current on and off of each lamp holder, and each current sensor is connected to a central data processor. The current sensor automatically senses the quality of the lamp, and the central data processor automatically records the time when the lamp breaks down or the number of times it is switched on and off, further reducing the labor intensity of human labor.

[0010] The controller is a PLC controller.

[0011] Compared with the prior art, the beneficial effects of the present invention are embodied in the following aspects:

[0012] (1) High test efficiency: 5 to 10 lamp holders can be set on each bracket, and 15 to 25 lamp holders can be set on each lamp holder. Therefore, 75 to 250 lamps can be tested at the same time, with high test efficiency;

[0013] (2) The test conditions of lamps on the same lamp pole are the same and more closely match the actual application environment, so the test results are more accurate;

[0014] (3) The test process is automatically controlled and the results are recorded by the central processor, so the degree of automation is high and the labor intensity is low. BRIEF DESCRIPTION OF THE DRAWINGS
