Embodiment
Illustrate embodiments of the present invention below by way of specific instantiation, those skilled in the art can be by this specification Disclosed content understands other advantages and effect of the present invention easily.The present invention can also pass through specific realities different in addition The mode of applying is embodied or practiced, the various details in this specification can also based on different viewpoints with application, without departing from Various modifications or alterations are carried out under the spirit of the present invention.
It should be noted that the diagram provided in the present embodiment only illustrates the basic conception of the present invention in a schematic way, Then only display is painted with relevant component in the present invention rather than according to component count, shape and the size during actual implementation in schema System, it is actual when implementing, and kenel, quantity and the ratio of each component can be a kind of random change, and its assembly layout kenel also may be used Can be increasingly complex.
The direct replaced type LED fluorescent lamp tube of the present invention uses filter form, in power network input and LED drive power Between a high frequency filter is set to filter out high-frequency and high-voltage harmonic wave so that only ac frequency passes through, so as to protect LED Fluorescent tube is without prejudice.Wherein, relatively low to the power requirement of high frequency filter, its price is relatively low, and is easily installed.
Referring to Figures 1 and 2, direct replaced type LED fluorescent lamp tube of the invention includes LED drive power 1, the and of LED lamp panel 2 High frequency filter 3.Wherein, the first end of high frequency filter 3 is connected with input ac power, the second end and the phase of LED drive power 1 Even, the 3rd end is connected with starter 4;LED drive power 1 is connected with LED lamp panel 2 again.
As shown in Fig. 2 when replacing traditional fluorescent tube using the direct replaced type LED fluorescent lamp tube of the present invention, nothing Starter need to be removed, only the first end of high frequency filter input ac power end need to be connected to, three-terminal link is in starter .
It is humorous that high frequency filter 3 is used to filter out ballast and the starter high-frequency and high-voltage that resonance is produced on startup when turning on light Ripple, only passes through input ac power.Specifically, it is used as LPF function, low pass cutoff in the high frequency filter of the present invention Frequency is 10KHZ, so as to be substantially filtered out more than 15KZ high-frequency harmonic.And the resonant frequency one of resonant mode fluorescent lamp As be in 20KHZ-40KHZ.
Reference picture 3, high frequency filter includes the first diode D1, the second diode D2, the 3rd diode D3, the four or two pole Pipe D4 and electric capacity C.Wherein, input ac power of the first diode D1 positive pole after being handled through Inductive ballast is connected, and bears Pole is connected with electric capacity C positive pole;Second diode D2 positive pole is connected with starter, negative pole and the first diode D1 negative pole and LED drive power is connected;3rd diode D3 positive pole is connected with electric capacity C negative pole, the zero line of negative pole and input ac power It is connected;4th diode D4 positive pole is connected with the 3rd diode D3 positive pole and LED drive power, negative pole and starter phase Even.
Preferably, electric capacity C uses high-voltage electrolytic capacitor, and its resistance to pressure request reaches 400V.According to the size of power of lamp tube, electric capacity C scopes are 10uF to 47uF, and rated temperature is 105 °.
First diode D1, the second diode D2, the 3rd diode D3, the 4th diode D4 all sames, using model 1N4007.1N4007 rated operational current is 1A, and reversely pressure-resistant is 700V.
LED drive power 1 is used to provide driving power supply for LED lamp panel.
Specifically, LED drive power can use insulating power supply, it would however also be possible to employ non-isolated power supply and the electricity of capacitance-resistance structure Source.What LED drive power was supplied to LED lamp panel belongs to high-end insulating power supply, meets TUV test requests.LED drive power it is defeated Go out voltage range and driving current relevant with lamp bead string and power, but it is little with high frequency filter relation.Due to also without 60W More than fluorescent tube demand exist, the maximum of high frequency filter bears power in more than 80W, therefore high frequency filter is only and power supply Input parameter is relevant.
The LED lamp bead of several circuits connection is provided with LED lamp panel 2, for sending light after power drives.Its In, the lamp bead arrangement in LED lamp panel after several LED lamp bead connection in series-parallel as shown in figure 4, access the positive and negative of LED drive power Between output electrode.Wherein, LED bead string is made up of the LED lamp bead of series aiding connection successively.
The arrangement of lamp bead causes whole fluorescent tube can not using form that is above-mentioned many and connecting so as to avoid single lamp bead from damaging The situation of work.Lamp bead and string group number is that have with the output voltage range of the general power of fluorescent tube and power supply, output current size Close, the relevance with high-frequency filter circuit is little.
In summary, direct replaced type LED fluorescent lamp tube of the invention without need to it is original access tube circuit do any Change;Without needing to remove original circuit block such as starter, you can directly carry out LED fluorescent lamp tube and conventional fluorescent fluorescent tube is replaced Change;Easy to operate, safe, cost is relatively low.So, the present invention effectively overcomes various shortcoming of the prior art and has height Spend industrial utilization.
The above-described embodiments merely illustrate the principles and effects of the present invention, not for the limitation present invention.It is any ripe Know the personage of this technology all can carry out modifications and changes under the spirit and scope without prejudice to the present invention to above-described embodiment.Cause This, those of ordinary skill in the art is complete without departing from disclosed spirit and institute under technological thought such as Into all equivalent modifications or change, should by the present invention claim be covered.
