Description

Discharge lamp

Technical field

The invention relates to a discharge light-emitting lamp body structure, which mainly aims at a structural change of the current discharge light-emitting lamp body, and changes the original straight-type discharge light-emitting lamp body into a planar discharge light-emitting lamp body to increase the luminous efficiency thereof. Background technique

High Intensity Discharge was developed in the period of Mercury Lamp 1901, Metal Halide Lamp 1941, Sodium Lamp 1965, Xenon Lamp In 1965, however, when mercury was discharged, although the ultraviolet light of 2,540 angstroms was mainly released by the energy level transition, the mercury atom also particularly liked to absorb the same energy of ultraviolet light (from low energy state to high energy state). When there is sufficient density of mercury, all of the released 2540 angstroms of ultraviolet light is absorbed. Thus, only the visible light (mainly near the blue light) released by other transitions that are not easily absorbed can pass through the initial stage of lighting the high-pressure mercury lamp, and the mercury is mainly present in the liquid state. So the initial stage was like a normal fluorescent lamp, but it lacked the fluorescent quality, so only the very weak light was seen. As the temperature gradually increases, the mercury gradually evaporates, producing more mercury vapor atoms and gradually emitting more visible light. In order to reduce the proportion of blue light, some high pressure mercury lamps have added a small amount of metal atoms. These are usually added in the form of metal halides. For example, adding sodium, strontium, iodine, etc. will increase the visible light in the warmer red section. Such high-efficiency discharge lamps are widely used in general household or commercial applications, such as: street lamps, projection lamps, vehicle lights, movie camera lamps, or lamps for advertising or lighting in projectors. In each of these various types of discharge lamps, a pair of discharge electrodes facing each other are placed in a discharge chamber filled with a discharge gas, and the illuminating effect is obtained by applying a predetermined voltage between the two discharge electrodes to decompose the discharge gas. A variety of luminescent and luminescent colors can be produced by selecting the applied discharge gas, the pressure of the discharge chamber, or other characteristics.

As shown in Fig. 1, a new type of illuminating lamp for a discharge lamp of the Chinese Patent Publication No. 507249, which is a durable illuminator having a simple structure and stable discharge characteristics, is shown in Fig. 1. The discharge electrodes 24 and 25, which are fixed to the respective sealing spacers 26 and 27, are inserted into the outer casing 23 from the ends of the discharge electrodes 24 and 25, and the outer casing 23 is a cylinder having the same inner diameter of the end points of the two openings. Formed by a glass material. In this case, the discharge vessel 28 is filled with the discharge gas, and the sealing spacers 26 and 27 are fused and fixed to the outer casing 23.

Further, as shown in Fig. 2, the Taiwanese Patent Publication No. 200504788 discharge tube provides a discharge tube which can easily form a cup-shaped electrode and has a long lamp life. The discharge tube 30 of the present invention is provided with an inner tube 32 fixed to the inner side of the side wall portion of the electrode 31, and the inner tube 32 is formed of a metal having a sputtering rate smaller than that of the electrode. According to the above configuration, the cup-shaped electrode 31 is easily formed by a metal material having a high workability with a high sputtering rate, and the cylindrical inner tube having a metal having a small sputtering rate is disposed on the cup-shaped electrode 31. On the inner side, the consumption of the electrode 31 due to sputtering can be suppressed. Thereby, it is possible to suppress the consumption of mercury in the discharge gas contained in the glass tube 33, and it is possible to realize a fluorescent discharge tube having a long lamp life.

As shown in FIG. 3, the Chinese Patent Publication No. 200304164 Mercury-short arc lamp is a mercury-short arc high pressure discharge lamp 41 for DC operation, and the discharge tube 42 has two. a neck 44 at the opposite end of the diameter, a neck 44 is fused to an anode 46 and a cathode 47 made of tungsten in an airtight manner, and the discharge tube 42 contains a filler composed of mercury and at least one rare gas, at least the cathode The material of the tip 43 further contains L 0 _{3 in} addition to tungsten, and the filler has a mercury content of at least ¹ mg/cm ³ and a maximum of 6 mg/cm ³ in the discharge tube. Summary of the invention

The Taiwan Taiwan Patent Publication No. 200404788 discharge tube is Change the discharge electrode to a cup shape to reduce the mercury consumption and increase its discharge life. However, if the electrode material is made into a cup, the amount of the cup material will be designed due to its performance, so the material will still be lost. Faster, and the brightness produced by the discharge is not much improved. · Taiwanese Patent Publication No. 200304164 Mercury-short arc lamp, which is a conventional two-electrode, so the brightness generated by the discharge Not much improvement.
