Inspection light assembly

Abstract

A portable cordless inspection light assembly (10) including a lamp (12) capable of producing a spectral distribution, which is substantially identical to daylight, color temperature. The lamp has a reflector portion (14) around its bulb and a light outlet lens (18) across its large end. The light includes a housing having a generally tubular housing portion. The lamp is mounted within an opening in that housing portion (24) adjacent one end with its large end across the opening and its reflector portion extending along the opening toward the opposite end of the housing portion. Passageway portions (30) of the through opening are provided around the large end of the lamp, and a fan assembly (32) within the opening can propel air through the opening over the outer surface of the lamp and through those passageway portions to cool the lamp. The housing includes a manually engageable handle portion (34), and supports a rechargeable battery (36) by which the bulb and fan assembly can be activated.

Description

technical field [0001] The present invention relates to a light source assembly that produces light, generally equivalent to sunlight, that can be used to inspect surfaces, such as freshly painted surfaces. Background technique [0002] There are many situations in which it is desirable to inspect a surface using light generally equivalent to sunlight, for example, to determine the color of a surface or to better view defects or irregularities located on the surface under such light. One such situation is when a surface (eg, that of an automobile body) is being shaded indoors, and it is impractical or impossible to move that surface outdoors into daylight. [0003] Lamps have been developed that produce light of substantially the same color temperature as daylight (for example, the lamp described in US Pat. No. 5,418,419 (McGuire) and available under the trade designation "SoLux" from Tailored Lighting Company of Pittsford, New York). [0004] Our previous experiments have ...

Problems solved by technology

However, those inspection light assemblies are supported on the ground or a fixed structure and are powered from AC power through converters and rectifiers, so they must be wired to a source of such power

Therefore, the light source cannot be easily moved on the surface, and the power socket must be plugged in before the light source assembly can be used, and the electric wire that limits the distance between the light source and the socket that can be used must be connected to the socket
