Abstract
The utility model relates to a low-power double-end high-voltage sodium lamp. The sodium lamp is provided with a quartz glass bulb, the inner part of which is provided with an arc tube and two ends of which are provided with a molybdenum sheet and a nickel head. Two ends of the arc tube are respectively connected with a corresponding molybdenum sheet through a support frame component. The glass bulb takes the shape of a straight tube and two ends thereof are pressed into the shape of a flat plate, and the support frame component is an elastic support element. The support frame component has reasonable structural design and can effectively relieve the expansion of materials in the lamp, and as the material of the support frame component is large in tensile coefficient, high in strength, resistant to high temperature and good in electric conductivity, the arc tube can be effectively protected from being damaged and the service life of bulbs is longer. The support frame component can be installed in the quartz glass bulb with general dimension, the coaxial degree and installation dimension of the bulb arc tube are accurate and the bulb is suitable to be matched with all types of lamps. The nickel head is covered with a porcelain head that is used for insulated protection and high in safety. The design is reasonable, the support frame component is accurate in structure positioning, the assembly is simple, the welding spots are few, the welding is easy and the working efficiency is improved.
Description
Technical field
The utility model relates to a kind of lighting apparatus, particularly a kind of small-power both-end high-pressure sodium lamp
Background technology
Small-power both-end high-pressure sodium lamp is good because of little, the general interchangeability of its volume, little power consumption, long service life, cost is relatively low and do not lure advantage such as worm, is widely used in floodlighting, floodlighting, decorative lighting, Landscape Lighting and houseplant cultivation etc.Existing small-power both-end high-pressure sodium lamp generally is used for closed light fixture, owing to have characteristics such as volume is little, working space is little, when operate as normal, the working temperature of bulb is higher, and the electric arc tube of small-power both-end high-pressure sodium lamp is connected to fixed structure, can not play mitigation to expanding with heat and contract with cold of material in the lamp, cause the sodium lamp arc tube in the bulb to be damaged, the bulb premature failure.
