Problems solved by technology

Because the power of a single LED is generally small, high-power LED lights require multiple LEDs to work in series. Since LED lights are usually welded on printed boards, LED lights may have virtual soldering, or LED lights may be damaged due to vibration, temperature changes, etc. Poor contact with the solder joints. In these cases, the LED drive power supply will have an open circuit load, resulting in damage to the LED drive power supply.

Abstract

An embodiment of the invention discloses an LED lamp driving power test method. The LED lamp driving power test method comprises the steps of simulating various open circuit states of an LED driving power; conducting an open circuit test on the LED driving power; and passing the test if the performance of the driving power is detected to be normal under the various open circuit states. According to the invention, the LED lamp driving power test method can be used for testing whether the open states of the LED lamp driving power would result in damage to the driving power at before an LED lamp leaves the factory, unqualified LED lamps can be prevented from entering the market, and the after-sales service cost is reduced.

Description

technical field [0001] The invention relates to the field of circuit testing, in particular to a testing method for an LED lamp driving power supply. Background technique [0002] Light Emitting Diodes (LEDs) have been widely used in recent years due to their advantages of long life, high luminous efficiency, low radiation, and low power consumption. LED lights are widely used in roads, tunnels, factories, shopping malls, residential areas and so on. [0003] The LED lamp includes a driving power supply and an LED, and the LED is a load of the driving power supply. Because the power of a single LED is generally small, high-power LED lights require multiple LEDs to work in series. Since LED lights are usually welded on printed boards, LED lights may have false soldering, or LED lights may be damaged due to vibration, temperature changes, etc. Poor contact with the solder joints, in these cases, the LED drive power will have a load open circuit, resulting in damage to the LE...
