[0003] The other is low-temperature gold-plating. Since the melting point of gold is about 1064.43°C, the gold-plated lamp can only be less than 40w per centimeter.
However, the reflectivity of gold plating is 95%, which is higher

Abstract

The invention discloses an infrared light tube or bulb with a double-color coating, which comprises an infrared light tube or bulb (1), wherein a filament (4) is arranged in the infrared light tube or bulb (1); the outer surface of the infrared light tube or bulb (1) is coated with a gold-plated layer (2); the surface of the gold-plated layer (2) is coated with a whitewashed layer (3); the whitewashed layer (3) is coated on the gold-plated layer (2); and the area of the whitewashed layer (3) is larger than that of the gold-plated layer (2). In the infrared light tube or bulb with the double-color coating provided by the invention, a gold-plated coating and a whitewashed coating can be realized on a high-power infrared lamp, so that high reflectivity of gold plating and high temperature resistance advantage of whitewashing are achieved, the reflecting utilization ratio of the high-power infrared lamp is increased greatly, and the energy-saving effect and high efficiency of the high-power infrared lamp are realized simultaneously.

Description

technical field [0001] The invention relates to an infrared lamp tube or bulb with a two-color coating. Background technique [0002] At present, in order to increase its directional radiation effect, the known infrared lamps all have reflective coatings on the transparent quartz glass tubes. There are basically two types of reflective coating materials, one is high-temperature white coating, and the material used is alumina or silicon carbide. The white-painted lamp tube coating is more resistant to high temperature, and can achieve a power of more than 80w per centimeter. But the downside of white-painted tubes is their low reflectivity. Only 65%. [0003] The other is low-temperature gold-plating. Since the melting point of gold is about 1064.43°C, the gold-plated lamp can only be less than 40w per cm. However, the reflectivity of gold plating is 95%, which is relatively high. Contents of the invention [0004] The invention provides a method for performing two-col...
