Abstract
The utility model discloses a ceramic metal halide lamp arc tube with higher lighting effect, which comprises a semitransparent aluminum oxide ceramic discharging cavity and a pair of electrodes. The semitransparent aluminum oxide ceramic discharging cavity consists of a straight tube type ceramic base and a ceramic cap, wherein the ceramic base is connected with a tail tube thereof in an arc transition form, the ceramic cap includes a ceramic plug and a linear tail tube, the pair of electrodes respectively extends into the tail tubes at two ends and into the ceramic discharging cavity, and the pair of electrodes is respectively led out through conductive leads and is connected in an airtight manner. The ceramic metal halide lamp arc tube leads temperature of the tube wall to reasonably be distributed, and has higher lighting efficiency and more uniform lighting.
Description
Technical field
The utility model relates to a kind of ceramic metal halide lamp arc tube, the higher ceramic metal halide lamp arc tube of particularly a kind of light efficiency.
Background technology
At present, existing ceramic metal halide lamp arc tube all adopts the two-end structure symmetrical manner.Vertical or press under most of use occasions of certain angle inclination burning-point, be positioned at the end temperature higher than the lower end of top because of convection effect has, therefore mainly be distributed in the lower end of electric arc tube by the metal halide gas molecular number of cold junction temperature decision, be diffused into upper end arc center's Region Decomposition and the luminous corresponding minimizing of metallic atom number is unfavorable for the raising of light efficiency and color rendering index.Adopt the littler geometry of the electric arc tube upper and lower side temperature difference, can obviously improve luminous efficiency and color rendering index, reduced luminous lamination simultaneously.
Summary of the invention
Technical problem to be solved in the utility model provides the higher ceramic metal halide lamp arc tube of a kind of light efficiency, and tube wall temperature is distributed rationally, and luminous efficiency is higher, and is luminous more even.
The utility model technical scheme that adopts of dealing with problems is: the ceramic metal halide lamp arc tube that a kind of light efficiency is higher, comprise translucent alumina ceramics discharge cavity and pair of electrodes, described translucent alumina ceramics discharge cavity is made up of straight pipe type pottery idiosome and ceramic cap, adopt arc transition to be connected between described ceramic idiosome and its tail pipe, described ceramic cap comprises ceramic plug and straight type tail pipe, described pair of electrodes stretches into the tail pipe at two ends respectively to the ceramic discharge chamber, described this drawn by conductive lead wire respectively electrode, and hermetic seal.
The geometric parameter of translucent alumina ceramics discharge cavity of the present utility model is corresponding with the power of lamp, is filled with starting gas, mercury in it and as the metal halide of luminescent substance, at least two kinds.The utility model is applicable to the manufacturing of the various power ceramic metal helide lamps of 20W～2000W; The material that the utility model is used for hermetic seal is a glass solder, and its component proportioning is by the material character decision in used sealing-in district.
Color rendering index of the present utility model, light efficiency and useful life are significantly increased with respect to the bulb that uses existing conventional ceramic metal halide lamp arc tube, draw following data after tested: the 35W that uses conventional ceramic metal halide lamp arc tube, 70W, the color rendering index of 150W and 400W bulb is respectively 60,62,65,68, light efficiency is respectively 77,85,85,85, be respectively 9000 useful life, 9000,9000,8000, and use 35W of the present invention, 70W, the color rendering index of 150W and 400 bulbs is respectively 68,68,72,72, light efficiency is respectively 85,90,115,130, be respectively 10000 useful life, 12000,12000,12000.
The beneficial effects of the utility model are: an end of translucent alumina ceramics discharge cavity is set to circular-arc, the other end is set to straight type tubulose, be placed on the below of working position with the utlity model has a circular-arc end, both can play the effect of the cold junction temperature that improves lamp, can obviously reduce the temperature difference of two ends tube wall again, helping more metal halide gas molecule spreads to whole electric arc corresponding region, thereby luminous efficiency and color rendering index have been improved, make the photochromic approaching unanimity of whole luminous zone, reduced luminous lamination simultaneously to external radiation.
