Example Embodiment

[0014] A tube-in-tube lighting lamp using a cold-cathode lamp tube, the outer tube 1 is provided with a reflector 4, the cold-cathode lamp 6 is installed on the working side of the reflector 4 through the tube clip 2, and the other side of the reflector 4 is installed. There is an inverter 5 , the inverter 5 is electrically connected to the output end of the cold cathode lamp 6 , and the electrodes of the input end of the inverter 5 are led out to both ends of the outer tube 1 through the lamp cap 3 . The outer tube adopts T5 / T8 specification. In this way, the existing lamp holder of T5 / T8 specification can be used, and it can be directly clipped on the existing lamp holder, so that the cost can be saved. The working side of the reflective sheet 4 referred to here is the reflective side of the reflective sheet.

[0015] The cold cathode lamp tube 6 is U-shaped or straight tube type, and the length is 500-1200mm.

[0016] The diameter of the cold cathode lamp tube 6 is 2.4-8....

Abstract

The invention discloses a tube-in-tube illuminating lamp adopting a cold cathode lamp tube, relating to an illuminating lamp. An outer tube is internally provided with a reflector, the cold cathode lamp tube is arranged on a working side of the reflector through a tube clamp, the other side of the reflector is provided with an inverter, the inverter is in electric connection with an output end of the cold cathode lamp tube, and electrodes at the input end of the inverter is lead out to the two ends of the outer tube through a lamp holder, wherein the outer tube is made by T5/T8 specification. The invention can sufficiently utilize the connection of a traditional lamp carrier of the T5/T8 specification, has long service life, low maintenance cost and good light directivity, and is very suitable for illumination in places, such as offices, schools, commercial centers and the like.

Description

technical field [0001] The invention relates to an illuminating lamp, in particular to a novel tube-in-tube illuminating lamp adopting a cold cathode lamp tube. Background technique [0002] Traditional T5 / T8 and other fluorescent lamps, as a kind of grille lighting and decorative backlight, have disadvantages such as high power consumption, short life, fast light decay, 50% attenuation at about 3000H, and low switching times of about 100,000 times. Long-term lighting and many times of switching will lead to premature aging of the lamp tube; severe stroboscopic, it takes a few seconds to flicker when it is turned on, and after several months of lighting, the brightness of the lamp tube will be significantly attenuated, and the brightness required by the human eye cannot be reached. , it will cause eye fatigue, which is not conducive to working in this environment for a long time, and the quality of the lamp tubes on the market is seriously uneven, requiring frequent replacem...
