Detection lamp equipped with light-emitting diode
The present application reveals a lamp and a method for detecting leaks in air-conditioning and refrigeration systems. The lamp uses one or more light-emitting diodes (LEDs) as a light source to detect fluorescent dyes that have been added to the air-conditioning or refrigeration system.
1. A lamp for detecting fluorescent dyes that have been added to an air conditioning or refrigeration system, wherein the fluorescent dyes reemit light at a wavelength greater than the wavelength of light emitted from the lamp, the lamp comprising:
a lamp housing;
at least one light-emitting diode within the lamp housing, the diode emitting light having a wavelength band effective to enhance the reemission of light from a fluorescent dye, and
wherein said miniaturized lamp is sized to facilitate maneuvering inside an engine compartment and around an air-conditioning system or refrigeration system.
2. The lamp of claim 1 , wherein the diode is a blue light-emitting diode.
3. The lamp of claim 1 , wherein the diode is a UV light-emitting diode.
4. The lamp of claim 2 , wherein the blue light-emitting diode is an indium gallium nitride semiconductor.
5. The lamp of claim 2 , wherein the blue light-emitting diode is a laser diode.
6. The lamp of claim 5 , wherein the laser diode is a gallium nitride based laser diode.
7. The lamp of claim 1 , further comprising a protector ring connected to the lamp housing.
8. The lamp of claim 7 , further comprising a lens positioned within the protector ring.
9. The lamp of claim 8 , wherein the lens is a filter selected from the group consisting of black, red, amber, yellow, green, blue, indigo, violet, UV light and full spectrum filters.
10. The lamp of claim 9 , further comprising a blocker glass.
11. The lamp of claim 9 , wherein the lens is a dichroic filter.
12. The lamp of claim 1 , further comprising a plurality of light-emitting diodes.
13. The lamp of claim 12 , wherein each of the light-emitting diodes emits the same color light.
14. A lamp for detecting fluorescent dyes that have been added to an air conditioning or refrigeration system, wherein the fluorescent dyes reemit light at a wavelength greater than the wavelength of light emitted from the lamp, the lamp comprising:
a lamp housing comprising a power source;
at least one light-emitting diode within the lamp housing, the diode emitting light having a wavelength band effective to enhance the reemission of light from a fluorescent dye, and
wherein said miniaturized lamp is sized to facilitate maneuvering inside an engine compartment and around an air-conditioning system or refrigeration system.
15. The lamp of claim 14 , wherein the power source is a direct current power source.
16. The lamp of claim 14 , wherein the power source is a solar power source.
