The technical scheme that its technical problem that solves the utility model adopts is: a kind of device of the LED of obtaining high-luminous-efficiency, it is characterized in that: it is made up of a sensing instrument and a LED lamp, sensing instrument comprises a voltage module, one current module, one brightness module, one thermal module, one temperature-sensitive sticker, one display unit and a shell, the LED lamp is installed on the outer casing underpart position, display unit is installed on the outer casing frontispiece position, voltage module, current module, brightness module, thermal module and temperature-sensitive sticker are installed on the enclosure position, voltage module, current module, brightness module, thermal module connects display unit respectively, voltage module, current module connects LED lamp to be measured respectively, brightness module is towards LED lamp to be measured, thermal module connects temperature-sensitive sticker, and temperature-sensitive sticker is installed on the enclosure position of contiguous LED lamp.

Described display unit can be a digital display table.

Described display unit can also be a pointer display list.

The beneficial effects of the utility model are: compared with prior art, there is following advantage in use really in this device: one, can learn the voltage and the electric current of this LED lamp to be measured by this sensing instrument, and the luminance of observing this LED lamp simultaneously, make the heating temp of this LED lamp drop to minimum and luminance can maintain optimum state; Two,, can allow the LED lamp under the situation that does not influence luminance, also can reach the purpose of the heating temp that significantly reduces the LED lamp, make prolong the useful life of LED lamp by this device; Three, also need not to install additional again heaviness and expensive heat abstractor, only need some simple in structure and cheap radiator structures, also can effectively allow the temperature of LED lamp significantly reduce.
