Claims
- 1. An inspection lamp for detecting refrigerant leaks from air-conditioning systems through illumination of fluorescent material added to the refrigerant, the inspection lamp comprising an LED pen light having an extendible handle and an LED lamp housing at one end of the handle, the lamp housing containing an LED, said inspection lamp further comprising;
a mirror assembly comprising a mirror; a clip for attaching the mirror to the lamp at or near the LED lamp housing; and an arm extending between the clip and the mirror, said arm having a hinge connection with the mirror for rotating the mirror to different reflection angles with respect to the LED.
- 2. An inspection lamp as in claim 1, wherein the LED emits light within a wavelength band below about 500 nm.
- 3. An inspection lamp as in claim 1, wherein
the handle has an upper flexible portion attached to the lamp housing and a lower portion, wherein the flexible portion may be bent to fit into hard-to-reach areas of air-conditioning systems.
- 4. An inspection lamp as in claim 3, wherein the LED emits light within a wavelength band below about 500 nm.
- 5. An inspection lamp as in claim 1, further comprising:
the handle having a grip section and telescoping sections adapted to be pulled out to extend the handle and pushed in to retract the handle; and a battery housing containing a battery, the battery housing being attached at one end thereof to the telescoping section that is furthest from the grip section when the handle is extended.
- 6. An LED inspection lamp for detecting refrigerant leaks from air-conditioning systems through illumination of fluorescent materials added to the refrigerant and lubricating oil, said inspection lamp comprising:
an extendable and retractable handle having a grip section and telescoping sections adapted to be pulled out to extend the handle and pushed in to retract the handle, a battery housing containing a battery, the battery housing being attached at one end thereof to the telescoping section that is furthest from the grip section when the handle is extended; an LED lamp assembly connected to the battery housing and containing an LED that emits light within a wavelength band below about 500 nm; and a mirror assembly having
a mirror, a clip for attaching the mirror to the battery housing, and an arm extending between the clip and the mirror, said arm having a hinge connection with the mirror for rotating the mirror to different reflection angles with respect to the LED.
