Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
120 words
A vaporous lamp comprising a source of electromagnetic radiation in a wavelength range and in an intensity which includes radiation capable of increasing the temperature of a radiation-absorbing body by up to 100 C. *, a light transmitting envelope at least substantially surrounding the source and, adhered onto the envelope, a coating of a multitude of minute capsules wherein each capsule is a radiation-absorbing body, has an average diameter of about 5 to 5000 microns, contains a vaporizable compound, is located on the envelope in relation to the source to absorb radiation and undergo a temperature increase, and has a polymeric capsule wall material inert with and undissolved by the vaporizable compound and unmelted and uncharred by the temperature increase.
Claim 2
Dependent Claim
120 words
A vaporous lamp comprising a source of electromagnetic radiation in a wavelength range and in an intensity which includes radiation capable of increasing the temperature of a radiation-absorbing body by up to 100 C. *, a light transmitting envelope at least substantially surrounding the source and, adhered onto the envelope, a coating of a multitude of minute capsules wherein each capsule is a radiation-absorbing body, has an average diameter of about 5 to 5000 microns, contains a vaporizable compound, is located on the envelope in relation to the source to absorb radiation and undergo a temperature increase, and has a polymeric capsule wall material inert with and undissolved by the vaporizable compound and unmelted and uncharred by the temperature increase.
Claim 3
Dependent Claim
