Description
Technical field
The invention belongs to technical field of lighting fixtures, relate to a kind of compact fluorescent lamp.
Background technology
The existing fluorescent lamp fluorescent lamp bulb that a kind of fluorescent material be coated with by bulb shell, inwall and low-pressure mercury glow discharge tube and resonant capacitance, lamp holder etc. form as: Chinese utility model patent application (98234197.0) discloses.After the high frequency electric source of the electric ballast of this bulb and coupling output is connected, glow discharge occurs in the low pressure glow discharge pipe, produce the ultraviolet ray of 253.7nm, and the fluorescent material that transmits fluorescence excitation bulb glass bulb inwall sends fluorescence, bulb is just bright.This fluorescent lamp bulb, light efficiency is high, energy-conservation, color rendering is good, has all advantages of cold light source, easy to use as incandescent lamp bulb, also longer useful life than fluorescent lamp, incandescent lamp.But this kind of fluorescent lamp adopts single light source, and when this light source damages, whole fluorescent lamp can't be used.
Fluorescent lamp (CFL) has now become the energy-conserving product of national political VIP and ordinary people widely known dawn, particularly be furnished with electric ballast and the integrated type product of selecting the E27 screw cap, this series products is referred to as electricity-saving lamp, and generally acknowledges that it be the unique suitable light source of replacement incandescent lamp at present.Many countries, comprise our China, also releases for this reason the compact fluorescent lamp of high-quality is sold to the policy of subsidizing.It is used that the electricity-saving lamp of 9W-15W fully can suitable domestic lighting, and the above compact fluorescent lamp of 18W can directly replace the above incandescent lamp of 100W, now also has the appearance of 85W and 150W high-power compact fluorescent lamp product, can partly replace the use of HID light source.This class lamp institute adapted electric ballast, from resolution element, develops into the use paster, integrated circuit even, and power factor reaches 0.98, and total harmonic distortion content (THD) is less than 10%, and the life-span of lamp is brought up to 10000h, and the Light modulating type product is also arranged.But the life-span of electricity-saving lamp is restricting the development of industry, some electricity-saving lamps are used the just jaundice of two or three months fluorescent tube, and blackout, and then just do not worked.The life-span of whole electricity-saving lamp is mainly depended on fluorescent tube and ballast, the light decay of electricity-saving lamp depend primarily on electronic powder the number, the tube wall load of fluorescent material and fluorescent tube, powder is poorer, the tube wall load more heavily light decay of pipe is also just more serious.The not necessarily fluorescent tube reason but blackout is just turned to be yellow, ballast is performed meritorious deeds never to be obliterated equally.In general, under the condition of fluorescent tube coupling, as long as fluorescent tube energy switch is more than 100,000 times (30S/ON, 90S/OFF), the life-span of electricity-saving lamp can surpass more than 30,000 hours mostly, bad be also because the electronic devices and components life-span to and terminate.Also have, nowadays electricity consumption is in short supply, and voltage ripple of power network is very large, and some areas are even up to ± 50%, even if the voltage fluctuation of the electrical network of developed country ± 15% left and right.The fluctuation direct result of electrical network is exactly the damage of electrical appliance, and the electrical appliance as electricity-saving lamp so particularly, because volume is little, internal temperature is high, the use surplus of components and parts is limited etc., and after voltage raises, the power of electricity-saving lamp is also with regard to corresponding rising, the internal temperature of electricity-saving lamp also raises very soon, because the electronic component design surplus is very little, the corresponding increasing of the internal loss of electricity-saving lamp, raise so also aggravate its internal temperature, so vicious circle, just aggravated the not long phenomenon of service life of energy-saving lamp.
