1. A cordless microscope comprising:
- a stand;
a stage-supported by the stand for holding specimens to be viewed;
an objective lens supported by the stand for magnifying an image of a specimen on the stage;
an eyepiece lens supported by the stand and coupled with the objective lens for further magnifying the image of the specimen and for permitting a user to view the image; and
a light source assembly for illuminating the stage, the light source assembly including —
a circuit board, and a plurality of LEDs mounted on the circuit board for, projecting light toward the stage, wherein the LEDs are arranged on the circuit board in a general Y-shaped configuration.

Abstract
A microscope (10) having an improved light source assembly (40) that provides sufficient illumination for sophisticated microscopic applications while requiring so little power that it may be operated with a small, rechargeable battery pack (46) that provides over 40 hours of continuous operation from a single charge. The light source assembly (40) has a bulb life of approximately 100,000 hours and operates at temperatures significantly below the operating temperatures of conventional microscope bulbs.
