The method involves conducting an auction in which the price paid by bidders is independent of their own bids, in which participants are provided with information concerning their competitors' bids as the auction progresses, and in which the confidentiality of high values is maintained. This provides the advantage of improving the economic efficiency of the auction design over the existing art.

Disclosed are an LED light converting resin composition, and an LED member using the same. The LED light converting resin composition comprises 20˜99 wt % of transparent resin, 0.8˜60 wt % of a lighting color converting fluorescent substance, and 0.2˜20 wt % of a light diffusing bead with an average particle diameter of 0.2˜30 μm. It is possible to emit a white or yellowish white light, like a conventional white light LED, only by independently using a white light emitting LED lens with no change in a blue, violet, or UV LED. There is no need to use a white LED which is relatively expensive and has a short life. Instead, as required, it is possible to easily replace a conventional LED lens with the disclosed LED lens by a user or an operator, thereby obtaining a mild white light with a required luminance. Thus, glaring, caused by a high-luminance white LED lighting, can be effectively reduced, thereby providing a milder lighting with improved comfort. Furthermore, the concern about the deterioration of a lighting device can be reduced due to a high heat-resistance, which increases economical efficiency.
