Document Type and Number:
Japanese Patent JP7338237
Kind Code:
B2
Abstract:
To provide an infrared absorption lamp that exhibits excellent infrared radiation suppression effects even when exposed to humid heat environments using infrared absorbing fine particles that maintain excellent infrared absorption characteristics even when exposed to humid heat environments, and to provide an infrared absorption lamp cover.SOLUTION: The infrared absorption lamp is formed with a layer containing surface-treated infrared absorbing fine particles on the surface thereof. The surfaces of the surface-treated infrared absorbing fine particles are coated with a film selected from at least one or more of a hydrolysis product of a metal chelate compound, a polymer of a hydrolysis product of a metal chelate compound, a hydrolysis product of a metal cyclic oligomer compound, a polymer of a hydrolysis product of a metal cyclic oligomer compound.SELECTED DRAWING: Figure 1
