Abstract
The utility model discloses a high-color-rendering-index sodium lamp, which belongs to the technical field of lighting equipment and particularly relates to a high-color-rendering-index sodium lamp. The sodium lamp improves the color rendering index and improves the illumination quality by adding calcium powder in the ceramic discharge liner, and the calcium radiates blue light and yellow radiated by sodium in the electric arc to synthesize white light.
Description
Technical Field
The utility model relates to the technical field of lighting equipment, in particular to a high-color-rendering-index sodium lamp.
Background
At present, a large number of LED lamps are adopted in the market for illumination, because the gallium arsenide material adopted by the LED lamps is very serious in environmental protection problem, the gallium arsenide material is more difficult to treat than a mercury lamp, and the gallium arsenide material is more environment-friendly when a sodium lamp is used, while the sodium ionizing radiation yellow light in the prior art is poor in illumination effect and limited in application range.
Disclosure of Invention
In view of the technical shortcomings, the utility model aims to provide a high-color-rendering-index sodium lamp which can ionize calcium element to radiate blue light and synthesize the blue light with yellow light radiated by sodium to improve color rendering index, improve illumination quality and enlarge application range.
In order to solve the technical problems, the utility model adopts the following technical scheme:
the utility model provides a high-color-rendering-index sodium lamp which comprises a lamp holder, a bulb shell, a support arranged in the bulb shell, a lamp wick fixed on the support and two electrode outgoing lines, wherein a semitransparent alumina ceramic inner container is arranged in the bulb shell, a discharge material is filled in the inner container, the discharge material is sodium and neon, argon and xenon gas, and calcium powder is added into the inner container.
Preferably, the calcium powder is coated on the inner wall of the inner container.
The utility model has the beneficial effects that: the sodium lamp improves the color rendering index and improves the illumination quality by adding calcium powder in the ceramic discharge liner, and the calcium radiates blue light and yellow radiated by sodium in the electric arc to synthesize white light.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the drawings without creative efforts.
Fig. 1 is a schematic structural diagram of a high-color-rendering-index sodium lamp provided by the utility model.
Description of reference numerals: 1-bulb shell, 2-bracket, 3-lamp wick, 4-lamp holder, 5-electrode outgoing line, 6-inner container and 7-calcium powder.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Embodiment 1, as shown in fig. 1, includes a lamp holder 4, a bulb 1, a holder 2 disposed in the bulb 1, a wick 3 fixed on the holder 2, and two electrode lead-out wires 5, a translucent alumina ceramic inner container 6 is disposed in the bulb 1, the inner container 6 is filled with a discharge material, the discharge material is sodium and neon-argon-xenon gas, each lamp of neon-argon gas is filled, xenon gas is not an essential product, the three gases are respectively filled, and are mixed together after being filled to generate penning effect to reduce starting voltage, and calcium powder 7 is added into the inner container 6.
Further, the calcium powder 7 is filled in the inner container 6.
Electrodes are arranged at two ends of xenon, discharge between the electrodes enables sodium vapor to emit yellow light, and calcium emits blue light and yellow light emitted by sodium in an electric arc to synthesize white light so as to improve color rendering index and improve illumination quality.
The sodium lamp improves the color rendering index and improves the illumination quality by adding calcium powder in the ceramic discharge liner, and the calcium radiates blue light and yellow radiated by sodium in the electric arc to synthesize white light.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the utility model. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
Claims (2)
