Abstract

The present invention belongs to lamp technical field and relates to a low-color temperature yellow xenon lamp. The lamp bulb of the low-color temperature yellow xenon lamp is filled with high-pressure gases; and trace metal halide and trace metal mercury are added into the lamp bulb. The mass percents of the above components are as follows: 78% to 85% of xenon, 10% of metal halide, 3% to 10% of argon, 1.4% to 1.6% of mercury, and 0.4% to 0.6% of krypton. When the low-color temperature yellow xenon lamp is electrified, the lamp bulb emits light, the color temperature of the lamp bulb ranges from 1800K to 2200k, penetrability of the light is strong, and illumination ability is high. The low-color temperature yellow xenon lamp is suitable for being used as a street lamp.

Description

Low colour temperature yellow xenon lamp

Technical field

The present invention relates to technical field of lamps, particularly relate to a kind of low colour temperature yellow xenon lamp.

Background technology

Street lamp is the light fixture providing illumination functions to road, generally there is sodium vapor lamp street lamp, Metal halogen lamp street lamp, LED street lamp, xenon lamp street lamp etc., although wherein sodium vapor lamp brightness is higher, but power consumption is bigger, attention energy-saving and emission-reduction worked along with country and the urgency of reducing energy consumption, LED street lamp obtains more popularization, but it is as using and also exposes light decay gradually, weak heat-dissipating, the problems such as light capabilities is poor, particularly in rainy day, greasy weather, LED light haze-penetrating capability strong (LED also can do the gold-tinted of 2200K but light wave shortens and is not used to the illumination of street lamp), make street lamp with LED white light run into extreme weather and often have the snowy city of mist and the north to be likely to affect road safety.

Xenon street lamp is not only energy-efficient, its power factor is more than 0.99, than LED energy-conservation 20%, than Metal halogen lamp energy-conservation 60%, more energy-conservation than Non-polarized lamp and high-pressure mercury lamp 65%, and there is high-color rendering, color rendering index 92Ra, its spectrogram is in close proximity to the spectrum of sunlight, is called " artificial minisun " by people, it is suitable for human visual experience, be not likely to produce visual fatigue, service life up to 12000-30000 hour, year light decay only have 3%, lumen degree sustainment rate: more than 90%, therefore apply more and more extensive in 8000 hours. But its colour temperature is generally from 3000K-12000K, wherein 4300K and 6000K is optimal colour temperature. But, for street lamp, low color temperature lamp has more obvious advantage. Low colour temperature " refer to warm colour gold-tinted system, its illumination comfort level is higher, strong particularly in misty rain weather light transmissibility, is conducive to improving roadway illumination quality. But, in low colour temperature field, xenon street lamp is still a blank, it does not have colour temperature is at the xenon lamp of below 2500K.

Summary of the invention

Present invention aims to the deficiencies in the prior art, and provide a kind of low colour temperature yellow xenon lamp, during this bulb luminescence, colour temperature is 1800K～2200K, and light transmissibility is strong, and light capabilities is good, is suitable as street lamp and uses.

The technical solution adopted for the present invention to solve the technical problems is: a kind of low colour temperature yellow xenon lamp, it is filled with gases at high pressure in lamp ball, and adding trace meter halogenide, trace meter hydrargyrum, each composition is by mass percentage: xenon 78%～85%, metal halide 10%, argon 3%～10%, hydrargyrum 1.4%～1.6%, Krypton 0.4%～0.6%.

Further, described metal halide includes scandium iodide, sodium iodide.

Further, described each composition is by mass percentage: xenon 78%, scandium iodide 5%, sodium iodide 5%, argon 10%, hydrargyrum 1.4%, Krypton 0.6%.

Further, described each composition is by mass percentage: xenon 80%, scandium iodide 5%, sodium iodide 5%, argon 8%, hydrargyrum 1.5%, Krypton 0.5%.

Further, the pressure of described lamp ball inner high voltage gas is 0.6Mpa

The invention has the beneficial effects as follows: a kind of low colour temperature yellow xenon lamp, it is filled with gases at high pressure in its lamp ball, and add trace meter halogenide, trace meter hydrargyrum, each composition is by mass percentage: xenon 78%～85%, metal halide 10%, argon 3%～10%, hydrargyrum 1.4%～1.6%, Krypton 0.4%～0.6%, and during energising, bulb is luminous, its colour temperature is 1800K～2200K, light transmissibility is strong, and light capabilities is good, is suitable as street lamp and uses.

Detailed description of the invention

Below in conjunction with specific embodiment, the present invention is further detailed explanation, is not that the practical range of the present invention is limited to this.

The low colour temperature yellow xenon lamp of the present embodiment, it is filled with gases at high pressure in lamp ball, and add trace meter halogenide, trace meter hydrargyrum, each composition is by mass percentage: xenon 78%～85%, metal halide 10%, argon 3%～10%, hydrargyrum 1.4%～1.6%, Krypton 0.4%～0.6%, when being not powered in lamp ball, the pressure of gases at high pressure is 0.6Mpa, wherein metal halide can be sodium iodide, potassium iodide, cesium iodide, scandium iodide, and the present embodiment is preferably used scandium iodide, sodium iodide.

As one preferred embodiment, each composition of material added in lamp ball is by mass percentage: xenon 78%, scandium iodide 5%, sodium iodide 5%, argon 10%, hydrargyrum 1.4%, Krypton 0.6%.

As another preferred embodiment, described each composition is by mass percentage: xenon 80%, scandium iodide 5%, sodium iodide 5%, argon 8%, hydrargyrum 1.5%, Krypton 0.5%.

Above two embodiment all obtains good result, during bulb luminescence, colour temperature is at about 2000K, and can pass through to adjust lamp ball internal gas pressure, colour temperature is adjusted between 1800K to 2200K, through on probation, its gold-tinted sent is very strong in misty rain sky penetrance, it is adaptable to road street lamp, and color developing is maintained at 80. By contrast, the high pressure sodium lamp that street lamp is commonly used is when colour temperature 2200k, and color rendering properties only has 25. Particularly often there is the snowy city of mist and the north to need the gold-tinted of 2000k to make street lamp, and use LED, the gold-tinted of 2200K can be done but light wave shortens and is not used to street lighting.

Finally should be noted that; above example is only in order to illustrate technical scheme; but not limiting the scope of the invention; although having made to explain to the present invention with reference to preferred embodiment; it will be understood by those within the art that; technical scheme can be modified or equivalent replacement, without deviating from the spirit and scope of technical solution of the present invention.
