Is high pressure sodium lamp the same as metal halide lamp?
High pressure sodium lamp and metal halide lamp belong to the gas discharge light source, which are produced by the principle of electric discharge and light emission under the electric field. But the performance structure is differentHigh pressure sodium lamp discharges light with high pressure sodium vapor, and the wavelength of its radiation light is concentrated in the sensitive area of human eye.The utility model has the advantages of wide irradiation range, long service life, less ultraviolet radiation, good fog permeability, etc.. But it has poor color rendering and is sensitive to voltage fluctuation.
Of course not. It's only under 15W. It's generic
The same principle, all belong to the HID light source. The structure of the arc tube is different from that in the tube.
Metal halide lamp is developed on the basis of high pressure mercury lamp. It overcomes the disadvantage of poor color rendering of high-pressure mercury lamp. Some metal halides are added to the high pressure mercury lamp, and the metal arc is continuously supplied to the arc through the cyclic action of the metal halide, and the metal atoms are excited by the arc in the arc to radiate light. It has many advantages, such as good light color, high light efficiency and little influence by voltage, so it is an ideal light source at present. The metal halide lamp with various colors can be made by selecting the appropriate metal halide and controlling the relative proportion.
