Abstract
The utility model relates to metal halide lamp field in particular to an iodine gallium lamp which is especially suitable for flat printing, protruding printing and PS version selenium edition, including a lamp head, a core column and an electrode therein, and a discharging cavity. The circular arc combined place of the discharging cavity and the core column is smeared with an insulation coating. The structure is beneficial to enhance the temperature at the circular arc combined place of the discharging cavity and the core column of the iodine gallium lamp, the steam pressure in the discharging cavity is higher, so the performance of the light and the color of the lamp is improved, meanwhile, the manufacturing process is simple and the service life is pronged.
Description
Technical field
The utility model relates to the metal halide lamp field, especially a kind of Iodine gallium light that is specially adapted to print flat stamping, protruding seal, PS version selenium version.
Background technology
Iodine gallium light is that a kind of metal halide lamp claims metal halid lamp again, and Iodine gallium light is in the quartz glass discharge cavity, charges into gallium iodide, quantitative mercury and rare gas, and there is tungsten filament electrode at two ends.After Iodine gallium light is lighted, when beginning to discharge dim light.The heat of discharge heats discharge cavity gradually, and the temperature of discharge cavity is slowly raise, and the vapour molecule of mercury and gallium iodide increases sharply, and is diffused into participation discharge in the electric arc.Along with the rising of steam pressure, operating voltage also raises, and electric current reduces.After treating that operating voltage and operating current are normal, just enter stable operating state, send strong light.In addition, after lamp was lighted, the heat of discharge generation heating discharge cavity, spread to arc center from the tube wall evaporation then attached to the gallium iodide in the tube wall.After the gallium iodide molecular diffusion entered the high-temperature electric arc center, the gallium iodide molecule resolved into metallic atom and halogen atom under the high temperature of electric arc.Metallic atom is excited in electric arc and is sent the spectrum of properties of this metal.On the other hand, the metallic atom of arc center and halogen atom are also to the tube wall diffusion, and tube wall temperature is far below arc temperature.When metallic atom and halogen atom meet in colder tube wall zone, they once more chemical combination form halide.To arc center's diffusion, circulation constantly provides metal vapors to electric arc to halide and so forth, makes lamp constantly give off strong light again.
Original Iodine gallium light influences the result of use of Iodine gallium light in the temperature of the circular arc junction of discharge cavity and stem stem and the temperature heterogeneity of discharge cavity, also has influence on the useful life of Iodine gallium light simultaneously.
Summary of the invention
In order to overcome above-mentioned deficiency, provide a kind of efficient, result of use is good, the Iodine gallium light that life-span is high, the technical solution adopted in the utility model is: a kind of Iodine gallium light, comprise electrode, discharge cavity in lamp holder, stem stem, the stem stem, and smear heat insulation coating in the circular arc junction of discharge cavity and stem stem.
The beneficial effects of the utility model are: the heat insulation coating of the circular arc junction of discharge cavity and stem stem makes herein the temperature and the temperature in the circular discharge chamber at middle part even, improved the quantity of participating in the gallium iodide of discharge, make the Iodine gallium light discharge efficient, discharge effect is good, has improved the useful life of Iodine gallium light simultaneously.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and example.
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1, lamp holder, 2, stem stem, 3, electrode, 4, discharge cavity, 5, heat insulation coating.
Embodiment
A kind of Iodine gallium light as shown in Figure 1 comprises lamp holder 1, stem stem 2, and the electrode 3 in the stem stem 2, discharge cavity 4 is smeared heat insulation coating 5 in the circular arc junction of discharge cavity 4 and stem stem 2.
Claims (1)
1, a kind of Iodine gallium light comprises electrode (3), discharge cavity (4) in lamp holder (1), stem stem (2), the stem stem (2), and it is characterized in that: heat insulation coating (5) is smeared in the circular arc junction at discharge cavity (4) and stem stem (2).
