OPERATION LAMP AND ILLUMINATION UNIT THEREOF
First Claim
1. An operation lamp, comprising:
- a plurality of illumination units, each illumination unit having a substrate on which a plurality of LED light source sets being installed, each LED light source set being formed with a pair of light permeable holes on the surface of the substrate, a connection bridge being installed between each pair of light permeable holes for the installation of light emitting diode;
the top of each LED light source set being installed with a reflection mirror, at least two focusing devices being provided between the reflection mirror and each pair of light permeable holes, the distance between the reflection mirror and the light emitting diode being altered through adjusting each focusing device so as to adjust the oblique angle of the reflection mirror, such that each illumination unit reflecting and concentrating and focusing light to form a concentrated light beam and projecting to a pre-set projection point of each illumination unit;
a fastening seat, the center thereof being formed with a chamber, the periphery thereof being installed with a plurality of sliding slots arranged with equal angles, each sliding slot being served to allow a connection part extended from the inner end of each illumination unit to be inserted;
a focus adjusting device, an upper portion of a rotation handle thereof being passed through the bottom of the fastening seat;
after being sleeved with a screw rod, capable of synchronously rotating with the rotation handle, in the chamber, the top of the rotation handle being connected with an end sealing member;
an elevating ring being sleeved at the outer end of the screw rod, the elevating ring being connected to the connection part at the inner end of each illumination unit, and at least one guiding rod being installed between said elevating ring and said screw rod;
through rotating said rotation handle, each guiding rod being converted to perform a linear movement with the rotation of said screw rod, such that the elevation angle of said inner end of each illumination unit being adjusted so as to adjust the illumination area of concentration light beam of each illumination unit; and
a lamp housing, the top center of the inner wall thereof allowing the fastening seat to be connected and fastened, the bottom periphery thereof being inwardly extended with a bottom plate for connecting with the outer end of each illumination unit.

Abstract
The present invention relates to an operation lamp, consists of a plurality of illumination units, a fastening seat, a focus adjusting device and a lamp housing. The illumination units are designed to be modularized, so a plurality of LED light source sets and reflection mirrors can be processed with a rapid focus adjustment for allowing each illumination unit reflecting and concentrating and focusing light for forming a concentrated light beam. Moreover, after the plural illumination units and the lamp housing are assembled, through adjusting the height difference between at least two pivot parts at the outer end of each illumination unit and supporting members, the left/right oblique angle of the illumination unit is able to be adjusted, such that each concentrated light bean can be precisely adjusted to pass through the lamp center. Moreover, by adjusting the focus adjusting device, the elevation angle of the inner end of each illumination unit is adjusted, such that the concentrated light beam is able to be freely adjusted to any projection location in the horizontal direction, so as to adjust the illumination area.
