Description
Technical field
The present invention relates to a kind of flat-type light source, particularly relate to a kind of by multi-disc cold-cathode fluorescent plant lamp (Cold Cathode Fluorescence F1at Lamp, the CCFFL) flat-type light source that is constituted.
Background technology
Along with industry is flourishing day by day, digitization tools such as mobile phone (mobile phone), digital camera (digitalcamera), digital camera (digital video camera), notebook computer (notebook), desktop computer develop towards direction more convenient, multi-functional and attractive in appearance invariably.Yet, the display screen of mobile phone, digital camera, digital camera, notebook computer, desktop computer is indispensable man-machine communication interface, the display screen by the said goods can bring more facility for user's operation.In recent years, display screen on most mobile phone, digital camera, digital camera, notebook computer and the desktop computer all is main flow with the LCD, yet because LCD itself does not have luminous function, so must be below LCD, and then reach the function of demonstration by a module backlight so that light source to be provided.
Known common module backlight is made of a fluorescent tube, a reflex housing (holder) and a light guide plate (LGP).Above-mentioned light guide plate can be converted to the linear light that fluorescent tube sent the kenel of area source, because fluorescent tube is disposed at the side of light guide plate usually, so it is relatively poor by the area source homogeneity that light guide plate is throwed, so must be on the light-emitting face of light guide plate configurable number layer blooming piece (as diaphragms such as diffusion sheet, brightening pieces), yet light guide plate and blooming piece cost an arm and a leg, and it causes the cost of module backlight to improve.In addition, because fluorescent tube, reflex housing and light guide plate all are independent members, must be with a glue frame that above-mentioned fluorescent tube, reflex housing and light guide plate carrying is fixing in addition.So from the above, this kind module backlight is comparatively loaded down with trivial details in assembling, and assembly cost also can't further reduce.Therefore, cold-cathode fluorescent plant lamp becomes one of main flow of module backlight gradually.
Cold-cathode fluorescent plant lamp is a kind of electricity slurry light-emitting component, and it mainly is to utilize after electronics penetrates by negative electrode, and the blunt gas between negative electrode and the anode produces collision in the gaseous discharge cavity, and with gas ionization, excite to form the electricity slurry.Afterwards, the excite state atom that is excited in the electricity slurry can be got back to ground state to radiate ultraviolet mode, and the fluorophor in the further excitation plane lamp of the ultraviolet ray meeting of being radiated and produce visible light.Because cold-cathode fluorescent plant lamp has lower calorific value and good illumination efficiency and homogeneity, so cold-cathode fluorescent plant lamp has been applied on Backlight For Liquid Crystal Display Panels or other applications.If general large-sized cold-cathode fluorescent plant lamp difficulty comparatively on making will be applied in large-sized display or lighting device the time, will face problems such as cost of manufacture is higher, yield is on the low side.Based on above-mentioned reason, during cold-cathode fluorescent plant lamp is used in usually, in the undersized LCD.
This shows that above-mentioned existing flat-type light source obviously still has inconvenience and defective, and demands urgently further being improved in structure and use.In order to solve the problem that flat-type light source exists, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, and common product does not have appropriate structure to address the above problem, this obviously is the problem that the anxious desire of relevant dealer solves.
