Background

The reason why incandescent lamps are mostly used in China at present for voice control illumination, such as stairs, passageways, basements and the like, and fluorescent energy-saving lamps cannot be applied to voice control illumination is that the fluorescent energy-saving lamps operate by utilizing the principle of gas discharge, are long in starting time, and if the fluorescent energy-saving lamps are frequently started for a short time, the service life of the fluorescent energy-saving lamps is seriously influenced, so that lamps with other energy-saving modes need to be provided.

In order to overcome the technical defects, the invention provides a method for effectively solving the problem that the sound control lamp still possibly causes energy waste.

In view of the above-mentioned drawbacks, the present designer is actively making research and innovation to create a method for manufacturing a lamp for backlight module inspection, so that the lamp has industrial application value.

Disclosure of Invention
