Abstract

The invention discloses the application technology of a white light LED on water and electrical instruments, which mainly comprises following steps: selecting a white light LED as the light source, and selecting ZXSC310 of ZETEX as control drive. The technology is reasonable and smart. When encountering trip at night, we can install, debug and maintain the equipment under poor visual environment and power off condition by means of the white light LED equipped on the produced water meter and ammeter without the need of lighters. The flashlight is battery-powered to ensure the normal use in power-off circumference; and flashlight is designed to a tube shape, so that the flashlight can be inserted into the housing of the instrument like touch sticks of many PDAs when the flashlight is idle and can be pulled out when used, thus achieving excellent promotional value.

Description

technical field [0001] The invention relates to the technical field of instrument equipment, in particular to a technology for maintaining hydropower instruments in a dark environment. Background technique [0002] In many cases, hydroelectric meters are installed in relatively dark environments, for example, water meters may be installed under shaded wells, and electric meters may be installed in dark rooms of buildings. Or in special emergency situations, it is necessary to maintain the instrument in a dark environment. Contents of the invention [0003] The object of the present invention is to provide an application technology of white LEDs on hydroelectric meters that can effectively overcome the above-mentioned defects and facilitate instrument maintenance in dark environments. [0004] In order to achieve the above purpose, the present invention adopts the following technical solution: an application technology of white light LEDs on hydroelectric instruments, whic...
