Description
Technical field
The utility model relates to LED illumination, in particular, and a kind of LED fluorescent tube.
Background technology
Along with the quickening of modern life rhythm and the raising of quality of life, life content is more and more rich and varied, house, school, office, street, market, factory and enterprise and all kinds of public place of people's live and work, all used all kinds of lightings, wherein main is incandescent lamp and fluorescent lamp.
Fluorescent lamp is to utilize THE FILAMENT DISCHARGE AND, make inert gas and mercury vapour in fluorescent tube produce ultraviolet ray, thereby the fluorescent material of exciter lamp inside pipe wall makes its luminous a kind of lighting.It is the revolution based on after incandescent lamp.Fluorescent lamp compared with original incandescent lamp not only economize on electricity, the efficiency of illumination is high, and long service life.Fluorescent lamp service life is 10000 hours, and luminous efficiency can reach 26% of input energy, throws light on soft, and dazzle is little, and light efficiency is in 50lm/w left and right; And only have the service life of incandescent lamp about 1000 hours, available light energy probably only has 2%-3%, and most energy lose with hot form, the about 9lm/w of light efficiency left and right.
Because fluorescent tube contains a large amount of inert gases, mercury vapour and fluorescent material, unavoidably produce and use procedure in there will be evaporate into atmosphere in phenomenon, cause environmental pollution.Secondly, in fluorescent lamp circuit, use ballast, starter, needed a large amount of silicon steel sheet and copper cash, improved cost and power consumption, and produced a large amount of high-intensity magnetic fields, caused electromagnetic interference.
Illumination is one of main energy resource consumption mode, and the lighting energy consumption in the whole world has accounted for 1/5th of world's total energy consumption according to statistics.China has just met with the crisis of electricity shortage again and again since the beginning of this century, especially, along with the development in epoch, resident and commercial power demand constantly increase, and existing supply of electric power can not meet people's lives and industrial needs far away.China is in the urgent need to the New Product that can save energy resource consumption, to solve the problem of supply of electric power deficiency.
China is the production and consumption big country of incandescent lamp, looks into according to middle information business network regulation, and in only 1～November in 2013, China's incandescent lamp output has reached 42.1 hundred million.According to measuring and calculating, Chinese electric consumption on lighting accounts for 12% left and right of Analyzing Total Electricity Consumption.If the incandescent lamp in use is all replaced with to energy-saving lamp, 48,000,000,000 kilowatt hours of can economizing on electricity in year, are equivalent to reduce 4,800 ten thousand tons of CO2 emissions, and energy-saving and emission-reduction have a high potential.
LED(Light Emitting Diode, light emitting diode) be a kind of solid-state semiconductor lighting device, it is directly converted into light electricity; LED light fixture has fabulous power savings advantages, light efficiency can reach 100lm/w, 10 times of left and right of incandescent lamp, specialty research shows the LED electricity-saving lamp of 12 watts, within the time that uses 50,000 hours, use and exceed 5 years half continuously, compare with 60 watts of incandescent lamps that can send identical light, consume less 2400 degree electricity, nearly 1200 yuan of saving fund.Chinese population radix is large, and the usage quantity of bulb is surprising especially, if national people use energy-saving illumination, calculates the only annual generated energy that just can save a Three Gorges Dam of LED street lamp project through science.
Therefore since 2008, China just started to advocate use energy-saving illumination, and had dropped into a large amount of manpower, material resources and financial resources and widelyd popularize the incandescent lamp that energy-saving illumination replaces high energy consumption in China, to realize more efficiently utilization and the waste still less of national electric power.The popularization of China's energy-saving illumination in recent years has obtained gratifying achievement, has reduced greatly the pressure of national grid.On August 8th, 2011, the China national Committee of Development and Reform has announced " China eliminates incandescent lamp route map (exposure draft) ", will thoroughly eliminate use general lighting incandescent lamp by 2016, and the energy efficient lighting system that is representative by LED is replaced.
LED is that a very little wafer of piece is encapsulated in epoxy resin the inside substantially, its very little, very light.The wafer that its core is made up of p-type semiconductor and N-shaped semiconductor has a transition zone between p-type semiconductor and N-shaped semiconductor, is called p-n junction.In the PN junction of some semi-conducting material, the minority carrier of injection and majority carrier compound tense can discharge unnecessary energy with the form of light, thereby electric energy is directly converted to luminous energy.PN junction adds backward voltage, and minority carrier is difficult to inject, therefore not luminous.When it is during in forward duty, two ends add forward voltage, and electric current flows to negative electrode from LED anode, and semiconductor crystal just sends the luminous ray of different colours, the power of light and current related.
LED fluorescent lamp is all the same in overall dimensions with traditional fluorescent lamp, length has tetra-kinds of 60cm, 90cm, 120cm and 150cm, its power is respectively 8W, 9W, 10W, 12W, 15W, 18W and 20W, and 18W conventional fluorescent (Inductive ballast) actual power consumption is about 26W, 36W conventional fluorescent (Inductive ballast) actual power consumption is about 45W; LED fluorescent lamp is energy-efficient illuminating product.
Because LED is solid luminescence device, and operating on low voltage, multiple monomer LED luminescent device connection in series-parallel must be mixed to connect using, so in the fluorescent tube of LED fluorescent lamp, LED number used is conventionally more than 100～200, as shown in Figure 1.Its circuit connects obvious all series connection, but connection in series-parallel mixes use.In general, wish that few, the in parallel quantity of series connection quantity is many.Like this, once there be a LED open circuit in certain a string circuit, only can make this string not working, and this string electric current will be shared in remaining several roads.For example, add up to the LED of 200, if connect to 8 strings 25 also, every string 30mA, the total current 750mA of 25 strings, have a stringly badly, and often a string electric current has only increased 1.25mA.In addition,, if the LED number of series connection is less than 10, because the operating voltage of each LED is 2-3.6V, the supply voltage of series connection is lower than 35V, also just lower than world security voltage.
LED is solid luminescence light source, contains a large amount of mercury vapours in traditional fluorescent lamp, if broken mercury vapour can evaporate in atmosphere.And LED fluorescent lamp does not use mercury, and product is not leaded yet, and relative fluorescence lamp plays a protective role to environment, is Green Product.Compared with fluorescent lamp, LED fluorescent lamp, without ballast, without starter, without stroboscopic, noiselessness, is not only applicable to family, is more suitable in library office and all kinds of public place.
Traditional light fixture such as incandescent lamp and fluorescent lamp can produce a large amount of heat energy, and LED uses chemiluminescence technology, and electric energy is almost all converted to luminous energy, and luminous efficiency is high, can not cause the waste of the energy.The illumination of LED18W is equivalent to the illumination of traditional fluorescent lamp 40W, energy-efficient.The power consumption of LED lighting is quite low, and the operating voltage of each monomer LED is 2-3.6V.Operating current is 0.02-0.03A.In other words: the electric energy that it consumes is no more than 0.1W.LED light fixture power consumption is below 1/3rd of conventional fluorescent.
Owing to using direct-current working volts, can not produce scintillation, be conducive to read and office.Lamp body itself use be epoxy resin and and unconventional glass, firm firm, can not damage easily, can use relievedly.In light source, there is no mercury, not containing ultraviolet ray, safe and reliable in spectrum.Conventionally can exceed 100,000 hours actual life, is 10 times of conventional fluorescent, and LED also can recycling simultaneously.
LED lighting internal characteristics has determined that it is typical Green Product, is also scientific and technical innovation product of new generation.It is the perfect light source that replaces traditional lighting utensil, has a wide range of applications.But there is following shortcoming in existing LED lighting.
1, in order to solve luminous even problem, cause LED quantity too much.A very little LED wafer is encapsulated in epoxy resin the inside, and volume is very little, is solid luminescence device.If use the negligible amounts of luminescent device, will pull open the distance between luminescent device, there are a lot of empty positions and not luminous, cause whole lamp body non-uniform light, form the blackspot of light fixture.In order to reach the luminous uniform effect of lamp body, strengthen their arranging density as far as possible, use in a large number the LED device of smaller power, must cause the too much situation of LED quantity.
2, lamp body heating problem is serious: due to a large amount of LED devices that use in lamp body inside, this has just produced the problem of how to dispel the heat.Although LED device is cold light source, when each LED work, also can produce certain heat.A large amount of luminescent devices are together adjacent, just must solve heat dissipation problem, otherwise the time one are long, and lamp body will be out of shape, and has a strong impact on the service life of LED.One meter of fluorescent tube that left and right is long, only 26 millimeters of external diameters, such narrow space, to heat radiation, is individual very stubborn problem.
3, light fixture price: because having used in a large number LED light emitting semiconductor device, make LED light fixture expensive.Taking the T8 light fixture of 18W as example, more than 100 yuan, every cover, is five times of left and right of common a set of fluorescent lamp.Bring difficulty to popularization and application.
4, Breakdown Maintenance inconvenience, replacement cost are high: due to suitability for industrialized production, must use graininess LED luminous power device, could adopt SMD production technology.The result of bringing is thus that LED device is non-exchange.Cause a string luminescent device not work once there be LED to damage, light make light fixture occur blackspot different in size, heavy whole light fixture is scrapped, cause the high cost of maintenance replacing.
