Constant voltage output type LED controlling means abnormal state test switching box

Technical Field

The utility model relates to an ann's rule test field of LED controlling means product is particularly useful for constant voltage output type LED controlling means's abnormal state test.

Background

With the continuous development of LED lighting technology, LED control devices are also more and more important as important components of LED lamps. The LED control device is divided into a constant voltage output type and a constant current output type, the national mandatory standard GB19510.14 has clear requirements on safety test items of two types of LED control device products, an abnormal state is an important detection item, and whether the phenomenon that the products and the personal safety are damaged or not is mainly considered when the LED control device works in the abnormal state. The abnormal state test of the LED control device mainly comprises three items of detection: the LED control device is not connected with an LED module test, an output end short circuit test and a double-time LED module load test, the three tests need to be tested item by item, and the abnormal state test of the LED control device is unqualified as long as one is unqualified. In daily detection, the LED control device needs to be powered off and wired again after each test is finished so as to meet the test requirements specified by each test in the standard, and the wiring process is complicated, low in efficiency and unsafe.

Disclosure of Invention

The inconvenient and inefficient problem of wiring to existence in the test procedure, the utility model provides a constant voltage output type LED controlling means abnormal state test switching box of wiring convenience, security height only needs to carry out once wiring through this switching box alright accomplish the three experiment of abnormal state test through change over switch.

The utility model discloses a realize through following technical scheme: the adapter box for testing the abnormal state of the constant-voltage output type LED control device is composed of a power supply input terminal, an LED control device output terminal, an LED module load terminal and a contact switch. The power supply input terminal is connected with the input terminal of the LED control device and used for supplying power to the tested LED control device; the output terminal of the LED control device is connected with the LED module load terminal through the contact switch, and the adapter box is provided with two LED module load terminals and can meet the requirement of simultaneously accessing double loads; the function of the contact switch is to switch between tests.

The power input terminal, the LED control device output terminal and the LED module load terminal are all wiring terminals which can be wound and screwed up and can be plugged, so that various types of wiring can be facilitated, and the looseness is not easy to occur.

The power input terminal consists of 3 binding posts, which are respectively marked as L, N, PE and used for connecting a power supply; the input terminal of the LED control device consists of 3 binding posts, which are respectively marked as L1, N1 and PE1 and used for connecting an input power line of the tested LED control device, and the output terminal of the LED control device consists of 2 binding posts, which are respectively marked as R1+ and B1-and used for connecting an output power line of the tested LED control device; the LED module load terminals are divided into two groups, each group consists of 2 binding posts, which are respectively marked with R2+, B2-, R3+ and B3-, and are respectively connected with an LED module load.

The number of the contact switches is 3, the contact switches have different functions and are respectively K1, K2 and K3, K1 is used for short circuit of an output terminal of the LED control device, and K2 and K3 are used for connecting loads of the LED module, so that whether the tested LED control device works normally or not can be verified, and double loads can be applied; the contact switch not only has the break-make effect, can also play the indicating action, and when certain contact switch closed, its inside pilot lamp was bright promptly, played the warning effect.
