Embodiment Construction

[0017] A class C halogen lamp filled with the following mass percent gas in a quartz glass bulb,

[0018] Krypton 75~85%, Dibromomethane 6~15%,

[0019] Nitrogen 3~7%, Argon 3~7%,

[0020] The inflation pressure in the quartz glass bulb is 2.5 to 3.5 atmospheres.

[0021] Due to some problems in the manufacturing process, ordinary glass cannot be used as a light bulb. The thermal expansion coefficient of quartz glass is small, the melting point is high, and the transparency is good at high temperature, so it is suitable for the bulb of the tungsten-halogen lamp. Halogen tungsten lamps are available in upright circular and tubular shapes. Tubular tungsten halogen lamp structure. Its shell is made of high-temperature resistant quartz glass, and the tungsten wire inside is wound into a single or double helix, and there are several tungsten wire rings in the middle to prevent the filament from drooping. The inside of the lamp tube is evacuated and filled with inert gas and an...

Abstract

The invention discloses a grade-C halogen lamp. 75 to 85 percent of krypton gas, 6 to 15 percent of dibromomethane, 3 to 7 percent of nitrogen gas and 3 to 7 percent of argon gas are charged into a quartz glass bulb shell, and the charge pressure in the bulb shell is 2.5 to 3.5 atmospheres. Through an optimal halogen gas ratio and an optimal formula of auxiliary gases, the luminous flux of the lamp bulb, under the same conditions (the same voltage and constant lamp filament specifications, shape and size), can be improved by about 15 percent, the actually consumed power of the lamp bulb can be reduced by 5 to 8 percent, the actual life of the lamp bulb can be improved by 30 to 50 percent, and the X-ray shielding capacity of the lamp bulb can be improved by 20 percent. According to the data, under the same conditions, the light efficiency of the lamp can be improved considerably, energy can be saved and radiation can be reduced, so the lamp contributes to environment protection and health of human body.

Description

technical field [0001] The invention relates to a lighting technology, in particular to a class C halogen lamp. Background technique [0002] In the Twelfth Five-Year Plan, the Chinese government has listed energy efficiency as a top priority. In the next 15 years, our country is more committed to transforming China from the current low-efficiency energy user to a high-efficiency energy user. However, to improve the current situation of energy consumption requires joint and unremitting efforts from multiple industries. In today's world of global warming and energy shortage. Energy saving and consumption reduction has become an important topic in the world. [0003] Class C light bulbs are currently the replacement products advocated internationally. The formula of class C lamps in the prior art is mainly to add xenon gas, krypton gas, methylene bromide, carbon dioxide, and high-purity nitrogen. The functions and side effects of each gas are respectively: the function o...
