Abstract
The invention discloses a luminous pill of a warm-toned quartz metal halogen lamp, which comprises rare earth iodide, sodium iodide, scandium iodide and thorium iodide. The luminous pill adopts the thorium iodide to increase the color rendering index of the metal halogen lamp, when the mass percent of the thorium iodide is too low, the effect of increasing the color rendering index can not be achieved, and when the mass percent of the thorium iodide is too high, the color rendering index of the metal halogen lamp is reduced. The thorium iodide with the content has micro radioactivity, and the amount of radioactivity is within a safe range of human body, so that the quartz metal halogen lamp utilizing the luminous pill is easier to start. The invention discloses a luminous pill of a 150W quartz metal halogen lamp, and compared with the prior art, the luminous pill has the advantages that the luminous efficiency is larger than 851m/w, the luminous pill is golden yellow and has good color rendering property, the color rendering index is larger than 80, and the luminous pill can be applied to metal halogen lamps with different tube types from 2800 to 3200K.
Description
Technical field
The present invention relates to the Illuminant pill of quartz metal halide lamp, particularly colour temperature is the Illuminant pill of 2800-3200K.
Background technology
The green energy conservation electric light source that quartz metal halide lamp is a class high-luminous-efficiency, color rendering is good, the life-span is long, being widely used at all fields of national economy, is the high-quality electric light source of energy-saving and emission-reduction.
According to different purposes, different capacity, different profile, the kind of Metal halogen lamp to become on one hundred thousand.But color of sunshine Metal halogen lamp mainly contains three large series.
The first kind is with Pioneer Electronic Corp. of the U.S., and China is the scandium sodium series Metal halogen lamp of representative.The Main Ingredients and Appearance of its luminescent material is sodium iodide-scandium iodide-thorium iodide complex compound eutectic.The feature of such lamp is that luminous efficiency is high, color rendering index 65, life-span reach 5000-10000 hour.The light sent is frank white light (colour temperature ∽ 4000K), and such lamp shortcoming is that the lux maintenance lighted in 500 hours declines comparatively fast, more stable after 1,000 hours, is secondly that the color rendering of lamp is poor.
The HPI lamp that Equations of The Second Kind is representative with PhilipS, China.The eutectic of the composition of its main luminescent material---thallium iodide---indium iodide that is sodium iodide.The feature of such lamp is that luminous efficiency is high, the life-span is long, and what send is photochromic for refrigerant partially blue white (colour temperature 4700-5500K) and can simple substitute high-pressure mercury lamp.Shortcoming is that poor, the photochromic consistency of color rendering is poor.
The RE lamp that 3rd class is representative with OSRAM and China.The luminescent material of such lamp take iodate dysprosium (holmium, thulium)-sodium iodide-thallium iodide (indium)-cesium iodide as the complex compound eutectic of Main Ingredients and Appearance.The feature of this kind of lamp is color rendering good (Ra > 80), and closely daylight, correlated colour temperature > 5500K, light is cold white.But it is lower that shortcoming is luminous efficiency, useful life is not as front two classes.
The demand of market to low color warm tone (about colour temperature 3000K) Metal halogen lamp increases in recent years, north of China, North America, Northern Europe are because of world cold, the partially yellow warm tones luminous energy that Metal halogen lamp sends provides warm harmonious lighting atmosphere, allows people bask, happy.But the color rendering bad (color rendering index is less than 60) of usual low colour temperature Metal halogen lamp.To the illumination place that demand color correctly judges, as Zhi Chao factory, printing enterprise, printing and dyeing enterprise, exhibition center, jewelry shop and market, shop etc., be just not suitable for very much.
Summary of the invention
Technical problem to be solved by this invention is that to realize a kind of luminous efficiency high, and color rendering is good, the 150W quartz metal halide lamp of the golden yellow color of about colour temperature 3000K.
To achieve these goals, the technical solution used in the present invention is: a kind of Illuminant pill of warm tones quartz metal halide lamp, containing rare-earth iodide, sodium iodide, scandium iodide, and containing thorium iodide.
The mass ratio of described rare-earth iodide, sodium iodide, scandium iodide and thorium iodide is 1.0-1.2: 85.0-91.5: 8.5-9.5: 1.7-2.0.
The mass ratio of described rare-earth iodide, sodium iodide, scandium iodide and thorium iodide is 1.1: 88.1: 9.0: 1.8.
The colour temperature of described Illuminant pill is 3000 ± 200K.
The present invention utilizes thorium iodide to improve the color rendering index of Metal halogen lamp, when the mass percent of thorium iodide is too low, does not have the effect increasing color rendering index, and when its mass percent is too high, reduces the color rendering index of Metal halogen lamp on the contrary.And the thorium iodide of this content has trace-level activity, and exit dose is within the scope of human-body safety, this makes the quartz metal halide lamp using this Illuminant pill more easily start.
The present invention is 150W quartz metal halide lamp Illuminant pill, its compared with prior art luminous efficiency be >=85lm/w, in golden yellow, have color rendering good, color rendering index is greater than 80, can adapt to the metal halide lamp of the different casts of 2800-3200K.
Embodiment
Below in conjunction with embodiment, the present invention is described in detail.
Embodiment 1:
The Illuminant pill of quartz metal halide lamp, the mass ratio of the rare-earth iodide contained, sodium iodide, scandium iodide and thorium iodide is 1.0: 85.0: 8.5: 1.7.
Embodiment 2:
The Illuminant pill of quartz metal halide lamp, the mass ratio of the rare-earth iodide contained, sodium iodide, scandium iodide and thorium iodide is 1.1: 88.1: 9.0: 1.8.
Embodiment 3:
The Illuminant pill of quartz metal halide lamp, the mass ratio of the rare-earth iodide contained, sodium iodide, scandium iodide and thorium iodide is 1.2: 91.5: 9.5: 2.0.
Embodiment 1,2,3 all can be used for the 150W metal halide lamp of different cast, and its color rendering index is respectively 80,85,82, and colour temperature is respectively 2800K, 3000K, 3200K.
