Abstract
A pen-size inspection lamp for detecting fluorescent leak detection materials in hard-to-reach areas. The inspection lamp includes a housing, an extendible handle, at least one LED and a mirror assembly. The mirror assembly includes a mirror, a clip for attaching the mirror to the housing, and an arm extending between the clip and the mirror with a hinge connection for rotating the mirror to different reflection angles with respect to the LED.
Claims23
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 wherein the LED emits light within a wavelength band below about 500 nm.
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 our 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.
A handheld 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:
- a lamp housing;
- at least one LED mounted within the lamp housing and adapted to emit light within a wavelength band below about 500 nm which is adapted to cause the fluorescent materials added to the refrigerant to fluoresce in response to the emitted light;
- a handle having an upper flexible portion attached to the lamp housing and a lower portion, the upper flexible portion adapted to be bent to fit into hard-to-reach areas of the air-conditioning system for illuminating leaks in those hard to reach areas by locating the lamp housing in close proximity to the component being inspected;
- and
- an activation button located on the handle and electrically connected to the LED for permitting activation of the LED.
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 at least one LED which emits light within a wavelength band below about 500 nm;
- a mirror assembly including
- a mirror;
- a clip for attaching the mirror to the lamp at or near the LED lamp housing, the clip being removably attachable to the side of the 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.
An inspection lamp kit for detecting refrigerant leaks from air-conditioning systems through illumination of fluorescent material added to the refrigerant, the inspection lamp kit comprising:
- an inspection lamp including an LED pen light having an extendible handle and an LED lamp housing at one end of the handle, the lamp housing containing at Least one LED which emits light within a wavelength band below about 500 nm;
- a mirror assembly including a mirror, a clip for attaching the mirror to the lamp at or near the LED lamp housing, the clip being removably, attachable to the side of the 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;
- and
- a dye for introducing into the air conditioning system, the dye adapted to fluoresce when illuminated by light having a wavelength below about 500 nm.
