1. A LED package comprising:
a substrate;
at least one LED chip mounted on the substrate;
a transparent adhesive; and
a lens over the at least one LED chip, the transparent adhesive filled between the at least one LED chip and the lens, wherein a plurality of through holes is regularly defined in an optical non-effective portion of the lens, the through holes configured for increasing the air convection between inside and outside of the lens, light generated by the at least one LED chip travelling out of the LED package first through the transparent adhesive and then the lens.
2. The LED package as claimed in claim 1, wherein the through holes are defined in a bottom fringe of the lens.
3. The LED package as claimed in claim 1, wherein the through holes penetrate an inner surface and an exterior surface of the lens.
4. The LED package as claimed in claim 1, wherein the through holes are micrometer-scaled.
5. The LED package as claimed in claim 4, wherein the number of the through holes does not exceed 25.
6. The LED package as claimed in claim 1, wherein the through holes are nanometer-scaled.
7. The LED package as claimed in claim 6, wherein the number of the through holes exceeds 25.
8. The LED package as claimed in clam 1, wherein a plurality of cooling fins extends downwardly from a bottom of the substrate.
9. The LED package as claimed in claim 8 further comprising a frame receiving the substrate and the cooling fins therein.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A drilling machine comprising:
a machine body with a supporting mast having a drill head;
a drill pipe rotatable and translatable in relation to the machine body;
a loader for one or more drill pipes;
a supporting frame hinged to the loader and integral with the machine body,
wherein the loader is disposed at an angle which is variable with respect to the ground by rotating the loader around one or more hinges.
2. The drilling machine according to claim 1, wherein the loader is rotatable from a non-operating position to an operating position, causing the one or more drill pipes to become slanted with respect to ground level.
3. The drilling machine according to claim 1, wherein the loader comprises a plurality of sliders running on parallel guides, the plurality of sliders being configured to support the one or more drill pipes in positions parallel to one another and transversally to the parallel guides, further comprising one or more pins or bars perpendicularly to the parallel guides and transverse to and integral with at least one of said sliders, the one or more pins or bars being disposed between adjacent pipes, wherein the sliders are disposed to run on said parallel guides, thereby causing translation of said pins or bars and of said one or more drill pipes positioned between said pins or bars.
4. The drilling machine according to claim, 3, wherein each of the plurality of sliders comprises one or more lateral teeth andor lugs such that a translation of a first slider causes a translation of a second slider disposed adjacently to the first slider and such that the translation of the second slider causes the translation of the first slider.
5. The drilling machine according to claim 3, further comprising a translation device for a first slider, wherein the translation device causes a second, adjacent slider to translate upon a translation of the first slider.
6. The drilling machine according to claim 3, further comprising one or more guides, wherein each of the plurality of sliders runs on one of the one or more guides.
7. The drilling machine according to claim 6, further comprising a system of mobile mechanical arms configured to withdraw at least some of the one or more drill pipes from a pre-set withdrawal position inside the loader and to position the at least some of the one or more drill pipes at a level of a spindle or threaded fitting of said drill head.
8. The drilling machine according to claim 7, wherein one or more of the plurality of sliders are configured to run on said guides and to position the at least some of said one or more drill pipes in said withdrawal position.
9. The drilling machine according to claim 7, wherein to permit re-positioning of the drill pipes extracted from the ground in said withdrawal position in the loader, one or more of said plurality of sliders run on said guides, thereby causing said the drill pipes extracted from the ground to translate and move away from the withdrawal position.
10. The drilling machine of claim 1, wherein the guide is a double guide.
