LV, Light Value and EV, Exposure Value, are terms used to allow easy discussion of exposure and light without the confusion of the many equivalent combinations shutter speeds and apertures. LV refers to how bright the subject is. EV is the exposure setting on the camera. You may have seen them if you like to read the fine print of camera specifications. They are used to specify ranges of light levels for metering and autofocus.
1 eV = 1.6x10(-19) J, therefore 1 Joule = 6.25x10(18)eV. Hope that helps... I'm not sure what they mean by eV/J though as both eV and J are units of energy. The definition means that multiplying one eV by e, the charge on an electron (not the natural logarithmic e) gives you Joules.
