Description
Technical field
The utility model relates to a kind of high intensity discharge light source, particularly a kind ofly can directly replace high-pressure mercury lamp, is used for the single-ended internal trigger metal halide lamp of large tracts of land indoor and outdoor lighting and road lighting.
Background technology
Because single-ended internal trigger metal halide lamp is the internal trigger lamp, burning-point does not need other distribution subtrigger, and match appliances such as its ballast, light fixture, electric wire are all general with high-pressure mercury lamp, and therefore, single-ended internal trigger metal halide lamp can directly be replaced high-pressure mercury lamp and use.Along with wideling popularize of green illumination, energy-conserving light source, the high-pressure mercury lamp that light efficiency is low, color rendering is poor, the life-span is short is substituted by light efficiency height, color rendering single-ended internal trigger metal halide lamp good, life-span length just gradually.
The difference of single-ended internal trigger metal halide lamp and general lighting metal halide lamp is to have increased the internal trigger part, has increased on the structure of lamp to jump bubble and series resistance.Referring to Fig. 3, among the figure, 1 ' for spring coil, 2 ' for upper bracket, 3 ' for the sheet of cooling down, 4 ' for fly silk, 5 ' for discharge tube, 6 ' for lower carriage, 8 ' for resistance, 10 ' for bimetal leaf, 11 ' for wick, 12 ' for lamp holder, 13 ' for supporting pieces, 14 ' for glass bulb, 15 ' for connecting band, 17 ' for jump steeping, 18 ' being series resistance.Because series resistance 18 ' directly influences the service behaviour of jumping bubble 17 ': resistance is too big, and electric current diminishes, jumps bubble 17 ' and be difficult to work; Resistance is too little, and electrorheological is big, jumps bubble 17 ' and damages easily, so strict control series resistance 18 ' resistance.The single-ended internal trigger metal halide lamp of prior art in use, do not cut off because have between series resistance 18 ' and discharge tube 5 ', series resistance 18 ' is produced by discharge tube 5 ' when lighting a lamp infrared ray and ultraviolet direct irradiation, and the heat that is produced by discharge tube 5 ' toasts, its resistive layer is easily aging, and resistance raises, and finally causing jumping bubble 17 ' can't work, metal halide lamp can not open jumping, directly influences the useful life of lamp.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the defective that prior art exists, and provides a kind of rational in infrastructure, and series resistance value raises in the time of effectively suppressing burning-point, the single-ended internal trigger metal halide lamp that prolongs the useful life of lamp.
The technical scheme in the invention for solving the above technical problem is: this single-ended internal trigger metal halide lamp, comprise glass bulb, discharge tube, the sheet of cooling down, series resistance, jumping bubble, shelve assembly, wick and lamp holder, discharge tube, the sheet of cooling down, series resistance, jumping are steeped and are shelved assembly and all be contained in the glass bulb, glass bulb and wick sealing-in, lamp holder is contained in glass bulb and wick sealing-in place, its design feature is: the heat reflection sheet also is housed in the described glass bulb, and the heat reflection sheet is between discharge tube and series resistance.The heat reflection sheet separates discharge tube and series resistance, the infrared ray that the protective resistance rete produces during not by the discharge tube burning-point, ultraviolet irradiation and heat baking.
The single-ended internal trigger metal halide lamp of the utility model, the described assembly of shelving comprise and fly silk and resistance, and also comprise long insulated tube and short insulated tube, described long insulative is flying a lower end, and short insulative is in the resistance lower end.Long and short insulated tube prevents resistance, fly silk with the short circuit of heat reflection sheet and lamp does not work.
The single-ended internal trigger metal halide lamp of the utility model, described heat reflection sheet adopts stainless steel substrates, long and short insulated tube adopting quartz glass pipe.
The utility model compared with prior art has the following advantages: the single-ended internal trigger metal halide lamp of the utility model is rational in infrastructure; 1, in glass bulb, increases the heat reflection sheet; infrared ray, ultraviolet ray and the heat and the series resistance that produce during with the discharge tube burning-point separate; after series resistance is separated by the heat reflection sheet; overcome the defective that prior art exists; make resistive layer not by infrared ray, ultraviolet irradiation and heat baking; resistive layer is protected; effectively suppress its change in resistance; guarantee to jump the bubble operate as normal, prolong the useful life of lamp greatly.2, be set with long and short insulated tube flying silk and resistance lower end, long and short insulated tube prevents resistance when the lamp burning-point, fly silk and the short circuit of heat reflection sheet, makes lamp safety take-off burning-point.

Embodiment
Below by embodiment, in conjunction with the accompanying drawings the utility model is further elaborated.
Embodiment:
Referring to Fig. 1,2, this single-ended internal trigger metal halide lamp comprises glass bulb 14, discharge tube 5, the sheet 3 of cooling down, series resistance 18, jumps bubble 17, shelves assembly, heat reflection sheet 16, wick 11 and lamp holder 12; Discharge tube 5, the sheet 3 of cooling down, series resistance 18, jump bubble 17 and shelve assembly and all be contained in the glass bulb 14, heat reflection sheet 16 between discharge tube 5 and series resistance 18, glass bulb 14 and wick 11 sealing-ins, lamp holder 12 is contained in glass bulb 14 and wick 11 sealing-ins place.
Embodiment shelves that assembly comprises spring coil 1, upper bracket 2, the sheet 3 of cooling down, fly silk 4, lower carriage 6, long insulated tube 7, resistance 8, lack insulated tube 9, bimetal leaf 10, supporting pieces 13, connecting band 15.As shown in the figure, spring coil 1 withstands on glass bulb 14 tops, long insulated tube 7 is enclosed within and flies silk 4 lower ends, short insulated tube 9 is enclosed within resistance 8 lower ends, the sheet 3 of cooling down is fixed on the supporting pieces 13, and upper bracket 2 upper ends and spring coil 1 are connected and fixed, and connecting band 15 is connected with discharge tube 5, the heat reflection sheet 16 that is between discharge tube 5 and the series resistance 18 is fixed on the lower carriage 6, and series resistance 18 is connected with bimetal leaf 10, jumping bubble 17.
