Description

Method for charging gas discharge lamp into discharge medium and product obtained thereby

Technical field

The invention relates to the field of illumination lamps, and in particular to a method for charging a gas discharge lamp into a discharge medium and a product obtained therefrom.

Background technique

The discharge tube of the gas discharge lamp is filled with a discharge medium (such as mercury, argon, etc.). The prior art method for charging a discharge medium generally comprises vacuuming a vacuum system including a discharge tube to form a vacuum environment, then closing the vacuum device, charging the discharge medium, and finally sealing the discharge tube, such as Low-pressure gas discharge fluorescent lamp; or insert an amalgam in the discharge tube before vacuuming, and place the amalgam in the cooling system position of the vacuum system to prevent the temperature of the amalgam position from exceeding the amalgam rating during the vacuum environment treatment The temperature is evaporated away from the discharge tube, and then the vacuum system including the discharge tube is evacuated by a vacuum device to form a vacuum environment, the vacuuming device is turned off, and then the other discharge medium other than mercury is filled, and finally the discharge tube is sealed, such as a high-pressure metal halide lamp; or a high-temperature amalgam (rated temperature of about 800 ° C) is placed in a sealed chamber in communication with the discharge tube before vacuuming, the chamber is connected with an exhaust pipe, and then passed through an exhaust pipe through a vacuuming device After evacuating the vacuum system including the discharge tube and the cavity to form a vacuum environment, the vacuuming device is turned off and then charged. The external discharge medium is then used to discharge mercury in the high temperature amalgam to the discharge tube by high frequency heating, and finally the remaining high temperature amalgam in the chamber communicating with the discharge tube is separated from the discharge tube, and the sealed discharge tube forms a fluorescent lamp, such as A method of manufacturing an external electrode flat fluorescent lamp.

In the specific process, the vacuum system must first be vacuumed to form a vacuum environment, then the vacuuming device is turned off, the discharge medium is filled, and the discharge port of the discharge tube or the discharge tube is sealed; since the vacuum system exists A certain degree of slow air leakage, the ratio of the air leakage to the pumping capacity of the vacuuming device is negligible, and the vacuum environment of the vacuum system is not affected without closing the vacuuming device; however, the current process is charging The vacuuming device must be turned off before entering the discharge medium, and it takes a certain time for various processes to charge the discharge medium and seal the discharge tube. Therefore, during charging of the discharge medium and sealing of the discharge tube, the vacuuming device is closed, and the vacuum system is closed. Slow air leakage can affect the vacuum environment of the discharge tube, which affects the quality of the product, or in order to prevent the vacuum system from leaking, the vacuum level of the vacuum system is increased, and the cost is doubled.

In particular, the external electrode flat fluorescent lamp in the gas discharge lamp has the following advantages: 1. The service life is long, and the electrode has no filament, which solves the problem that the existing fluorescent filament electrode has short life and low switching impact, and the external electrode flat fluorescent lamp The electrode is formed by coating a conductive material such as graphite on the outer electrode position of the lamp glass. The life of the electrode can be designed to reach the life of the lamp material, such as the life of the glass, the life of the phosphor, and especially the number of switching times of the external electrode fluorescent lamp. It has reached 5 million times and the electrodes are still intact. 2, high light efficiency, light efficiency generally has two concepts: a, light-emitting end, refers to the light source efficiency (LM / W), b, the light-receiving end, refers to the end of the light illuminated surface, called the lighting efficiency; the light source has experienced The process of light source (such as incandescent lamp), line source (such as straight tube fluorescent lamp) to surface light source (flat lamp), because the position where the light receiving end is illuminated is generally required to be a planar lighting effect, such as ceiling lighting effect, therefore, Both the point source and the line source must be converted into planar illumination by the secondary light distribution of the luminaire. This conversion process reduces the light efficiency of the point source and the line source, such as the second step of the fluorescent lamp with a source efficiency of 65 LM/W. After the light distribution, the illumination efficiency is reduced to 40-50LM/W, and the light source effect of the flat lamp is consistent with the illumination effect of the light receiving end, generally reaching 50LM/W. 3, light quality, flat light due to large light-emitting area, soft lighting, no glare, is the requirement of high-quality lighting. Therefore, the external electrode fluorescent lamp is considered to be another revolutionary new light source after incandescent lamps, fluorescent lamps, electrodeless lamps and LEDs.

The structure of the existing external electrode flat fluorescent lamp generally has two types: one is a plurality of non-separable discharge tubes simultaneously in one fluorescent lamp, and the plurality of discharge tubes are arranged in parallel, and electrodes are disposed at both ends of each discharge tube, and all The electrode is connected as one body, such as the fluorescent lamp structure disclosed in the patent ZL200510058824.5; the other is a fluorescent tube having only one discharge tube, and the electrodes are disposed at both ends of the discharge tube, such as the fluorescent lamp structure disclosed in ZL201210148423.

There are generally two methods for manufacturing the external electrode flat fluorescent lamps:

1. One-time sealing method: the sealing around the discharge tube is completed in one time, and the peripheral seal forming the discharge tube of the flat fluorescent lamp is to close the vacuuming device after vacuuming the cavity formed by the sealed discharge tube to form a vacuum environment. A method in which the discharge tube is filled in a discharge medium and completed in one time. For example, in the patent number (ZL201210115470.), during the process, the cavity communicating with the discharge tube of the fluorescent lamp is a sealed process container that is not connected to the discharge tube; as in the patent number (ZL201210148423.) during the process, with the fluorescent tube discharge tube The communicating cavity is a structure connected to the discharge tube, and the fluorescent lamp is formed, and then the cavity and the fluorescent lamp are separated.

2. Secondary sealing method: The sealing around the discharge tube is completed twice. The flat fluorescent lamp is provided with a suction port connecting the discharge tube and the exhaust tube. Before the vacuum treatment, the discharge tube is sealed except the suction port, and then After evacuating the suction port of the fluorescent lamp discharge tube through the exhaust pipe to form a vacuum environment, the vacuuming device is turned off, the discharge tube is filled with the discharge medium, and finally the exhaust pipe or the suction port is secondarily sealed. For example, the patent (ZL200610038965.5) is provided with an exhaust pipe in the thickness direction on the fluorescent glass plate, first sealing the periphery of the discharge tube except the exhaust pipe, and then vacuuming the fluorescent lamp discharge tube through the exhaust pipe to form a vacuum environment, and then closing Vacuuming device, charging the discharge tube into the discharge medium, and finally sealing the exhaust pipe; as patent (ZL200510058824.5), each fluorescent lamp in the glass plate is connected with the discharge tube and the discharge channel and the exhaust pipe. The gas port seals the periphery of each fluorescent lamp in the glass plate except the suction port, and then evacuates the suction port of the fluorescent lamp discharge tube through the exhaust pipe to form a vacuum environment, closes the vacuuming device, and fills the discharge tube with the discharge medium. The exhaust pipe is sealed, and the secondary sealing of each suction port is performed, and finally each fluorescent lamp is separated.

Since the sealing material of the discharge tube of the external electrode fluorescent lamp generally uses low-temperature glass powder, the sintering time is longer, whether it is the primary method or the secondary method, the slow leakage of the vacuum system seriously affects the discharge tube during the closing of the vacuuming device. The vacuum environment affects the quality of the product, or in order to prevent the vacuum system from leaking, it is necessary to increase the vacuum level of the vacuum system and increase the cost.

Although the manufacturing process of the primary method is simpler than the secondary method and is more suitable for the mechanization and automatic production of the product, the two fluorescent glass plates of the primary method are placed inside the sealed cavity. During the process of forming the fluorescent lamp, the discharge medium enters the fluorescent lamp to discharge. At the same time, the tube remains in the cavity, especially the mercury residue in the discharge medium, which brings mercury pollution to the product manufacturing process.

Therefore, how to solve the vacuum environment of the manufacturing process of the gas discharge lamp and the external electrode flat fluorescent lamp discharge tube has important significance for product quality; how to solve the problem of mercury pollution in the manufacturing process of the primary method, and realize the industrialization of the external electrode flat fluorescent lamp and The rapid development is of great significance.
