For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of cold cathode shot-light, comprise lamp socket, and inverter is installed in the lamp socket, lamp socket lower end and cold-cathode fluorescence lamp assembly fasten, and the cold-cathode fluorescence lamp assembly is connected with inverter.

In the cold-cathode fluorescence lamp assembly, the plastic upper end fastens with lamp socket, and the outer shot-light cup of cathode fluorescent tube and cathode fluorescent tube is installed in the plastic lower end, and the electrode of cold cathode arc fluorescent tube is connected with the output of inverter.

The plastic lower end is provided with the screw-type groove.

Cathode fluorescent tube is a toroidal bend.

The control circuit of inverter adopts intelligent IC half-bridge driven control chip.

The cold cathode shot-light that the utility model provides, beneficial effect is as follows:

1, owing to adopt the cold-cathode fluorescence lamp assembly, can overcome the shortcoming of existing electricity-saving lamp or incandescent lamp, start rapidly, promptly promptly brighter; The light that provides is stable, and colour rendering is good, and glow frequency exceeds outside the frequency that human eye can discover, and no stroboscopic, scintillation reduce eye fatigue, effective vision protection, and long service life, energy-conserving and environment-protective, and maintenance is simply, and energy consumption is low.

2, adopt cathode fluorescent tube in the cold-cathode fluorescence lamp assembly, can reach more than 50,000 hours service life, is 15～20 times of common U type electricity-saving lamp life-span; Colour rendering index can reach 85～90Ra, can satisfy country-level efficiency, and colour rendering is good; Adopt high-quality three primary colours liquid crystal powder, with under the constant power, the light efficiency height can reach 75-85 lm/W, and is energy-conservation; The glass of fluorescent tube adopts crown glass, has the purple function of cutting, and can prevent effectively that ultraviolet light in the light is to the human injury.

3, will have electricity-saving lamp now and adopt rectifier to change into adopting under the high frequency of inverter at 50～60KHz to drive in the mode that drives under the low frequency of 50Hz, the stroboscopic human eye perceives under this high frequency less than, no stroboscopic, scintillation have been protected eyesight effectively; And can not bear repeatedly switch more than 1,000,000 time because of frequent switch damages, durable in use, do not need frequent replacing, maintenance cost is cheap.

4, mercury content can accurately be controlled in the cathode fluorescent tube, is that 2.5～4.5mg/ props up, and meets international standard, has protected environment.

5, can be the multiple pattern that changes of top only with lamp socket designs, to adapt to different lamp holders (can be suitable for the lamp holder of models such as E14, E26, E27, GU10, MR16), replace simply, can satisfy all kinds of common sockets easily, enlarge range of application, reduced use cost.

6, the control chip of inverter adopts intelligent IC half-bridge driven control chip; the parameter that self adaptation ZVT (ZVS) mechanism that adopts the control circuit of this IC chip detects in the lamp works process changes; can turn-off output circuit according to detected abnormal condition of lamp tube situation, defencive function is strong, safe and reliable.

7, plastic, cathode fluorescent tube and shot-light are cup-shaped becomes an integral body, and entire circuit is enclosed in the integral body by safety, use simple, change easily.

8, the screw-type groove of plastic lower end defines the installation site of cathode fluorescent tube and shot-light cup, prevents that effectively it in use is shifted.

9, cathode fluorescent tube adopts toroidal bend to significantly reduce the fluorescent tube volume, good looking appearance under the prerequisite that guarantees brightness.
