Description

Single internal tube metal halogen-sodium mixed-light lamp bulb

The utility model relates to a kind of lighting bulb, especially shows the single internal tube metal halogen-sodium mixed-light lamp bulb that tube core in the metal halogen-sodium is housed in its enclosure space.

Along with social development, material progress life requirement need provide the large area lighting bulb.The existing high intensity discharge light source that adopts has mercury lamp, sodium vapor lamp, metal fontanelle compound lamp, exists respectively that color rendering is poor, light efficiency is low; Color rendering is poor; Deficiencies such as light decay is big, the life-span is short.In the patent disclosure of the patent No. 94243484.6 " a kind of metal halogen-sodium mixed light lamp ", its structure adopts in sodium pipe cascaded structure in the pipe and golden fontanel, owing to being the physics mixed light, still exist complex structure, make inconvenience, mixed light is inhomogeneous, colour consistency is poor, and the life-span is short, the not high weak point of light efficiency.

The purpose of this utility model provides a kind of not only simple and compact for structure, good manufacturability, and have light efficiency height, good, the photochromic unanimity of color rendering, long single internal tube metal halogen-sodium mixed-light lamp bulb of life-span.

The purpose of this utility model is to realize like this, include lamp holder, stem stem, glass bulb, an exit of its stem stem is welded with the lower carriage that is framework, the other end that is welded with the lower carriage of bottom electrode is connected with the interior pipe that is marked with a certain proportion of argon, mercury metal, sodium metal and fontanelle compound, the other end of interior pipe is connected with the upper bracket that is framework that is welded with top electrode, the other end of upper bracket is supported on the top, top of glass bulb, another root exit of stem stem links to each other with lead, and the other end of lead links to each other with top electrode.

Pipe two ends folder is flat in the utility model indication.

Its operation principle of the utility model; Power supply is through the ballast current limliting, trigger produces 3,000 to four kilovolts of high voltage pulses and puts between the upper and lower electrode of interior pipe, make it to discharge, the high temperature of discharge generation makes element gasifications such as argon, mercury metal, sodium metal and fontanelle compound send own characteristic spectrum, the spectrum that is sent just mixes in electric arc, so be called " chemical mixed light ", there is not the mixed light non-uniform phenomenon in this mixed light sources, cooperation ratio to element is controlled, and can obtain the light source of photochromic unanimity.

The utility model is compared with prior art, and is simple in structure, and cost is low, good reliability, and it is abundanter also to have a spectral line, and color rendering is good, and the sunlight tone makes the people in high spirits, reduces tiredly, raises labour efficiency the high characteristics such as energy-conservation of light efficiency.Be applicable to the indoor and outdoor large area lighting.

Below in conjunction with accompanying drawing the utility model is further specified.

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model embodiment winding diagram.

Among the figure: 1-ballast, 2-trigger, 3-lamp holder, 4-stem stem, 5-lower carriage 6-interior pipe 7-bottom electrode 8-top electrode 9-upper bracket 10-argon 11-mercury metal 12-fontanelle compound 13-glass bulb 14-sodium metal 15-lead 16-bulb

As shown in Figure 1, lamp holder 3 links to each other with an end of glass bulb 13, one exit of the stem stem 4 in the glass bulb 13 is connected with the lower carriage 5 that has bottom electrode 7, the other end of lower carriage 5 is connected with the interior pipe 6 that is marked with a certain proportion of argon 10, mercury metal 11, sodium metal 14 and fontanelle compound 12, the other end of interior pipe 6 links to each other with the upper bracket 9 that has top electrode 8, the other end of upper bracket 9 is supported on glass bulb 13 tops, and another exit of stem stem 4 connects lead 15, lead 15 other ends utmost point 8 that Connects Power.

Fig. 2, power supply one output line is in series with ballast 1, is connected in series to another power line after in parallel with trigger 2 and bulb 16 again.
