Cold cathode spot lamp

Abstract

The invention relates to a cold cathode spot lamp, comprising a lamp holder. The lamp holder is internally provided with an inverter; the lower end of the lamp holder is fastened with a cold cathode fluorescent lamp component which is connected with the inverter; in the cold cathode fluorescent lamp component, the upper end of a plastic piece is fastened with the lamp holder; a cold cathode fluorescent lamp tube and a spot lamp cup outside the cold cathode fluorescent lamp tube are arranged at the lower end of the plastic piece; and an electrode of the cold cathode arc fluorescent lamp tube is connected with the output end of the inverter. By utilizing the cold cathode spot lamp, the defects of the existing energy-saving lamp or filament lamp can be defected, the provided light is stable,the color rendering property is good, the stroboflash and flicker phenomena are avoided, the vision can be effectively protected, the service life is long, the energy is saved, the environment is protected, the maintenance is simple, and the energy consumption is low.

Description

technical field [0001] The invention relates to a lighting fixture, in particular to a cold cathode spotlight. Background technique [0002] Existing indoor and outdoor decorative spotlights usually adopt energy-saving lamps (neon tube lamps) or incandescent lamps, which have disadvantages. [0003] The use of energy-saving lamps as spotlights has the following disadvantages: 1. Using a rectifier to drive, there is a stroboscopic phenomenon, which will have a great impact on vision, and frequent switching is easy to damage the driving components, short life, and needs to be replaced frequently. It is not suitable for indoors. External decoration; 2. The service life of the lamp tube is short, only about 8000 hours; 3. The color rendering is poor, and the color rendering index is usually difficult to reach 85Ra; 4. The mercury content in the lamp tube is difficult to control accurately, which is not conducive to environmental protection; 5. , Relatively high energy consumpti...
