Description
Technical field
The utility model relates to the driving power of LED fluorescent tube, particularly independently is installed in the convenient a kind of driving power installing, change in the LED tube lamp holder.
Background technology
The LED fluorescent tube needs special-purpose power drives; Existing most of products all are to adopt driving power is installed in the fluorescent tube radiator back side, add heat-shrinkable T bush at power supply driver, to insulate with metal heat sink; The driving power that adopts this mode to install; The heat that power supply distributes is difficult to spread out of because of the heat-shrinkable T bush parcel, and the heat of fluorescent tube radiator can be transmitted on the driving power again simultaneously, causes the power supply temperature to raise; Both influenced power source life, and can influence the life-span of LED luminescence chip again because the fluorescent tube local temperature that power unit is installed is higher; And owing to adopt the external branch body structure fluorescent tube of driving power, not attractive in appearance in appearance, install also cumbersomely, the user is difficult to accept.Be that driving power and LED substrate are done together in addition; Adopt the driving power of this mode; The power volume that holds in the lamp holder of same length is limited, therefore needs to simplify the function of power supply, causes the performance of power supply influenced; The ripple of output is bigger, influences the life-span of illumination effect and led chip.
The utility model content
In order to solve the above problems.The utility model provides a kind of LED lamp driving power source, can be installed in fluorescent tube inside, neither influences the performance that also do not influence attractive in appearance, the convenient installation and replacing.The technical scheme of the utility model is: include a lamp holder, and an input rectifying filtered electrical source plate, a current conversion power panel, an output rectification filtering power plate has two jacks on the described lamp holder, be positioned at the centre position of lamp holder; Lamp holder and light radiator are installed together; Have on the described input rectifying filtered electrical source plate with lamp holder on corresponding two contact pins of jack, it can pass jack and be installed on the lamp holder; Be fixedly connected by thin copper post between described input rectifying filtered electrical source plate, current conversion power panel and the output rectification filtering power plate; Connection between each circuit board then connects realization through lead.
As a kind of qualification; Described input rectifying filtered electrical source plate is the unit of EMI rectifying and wave-filtering function, and said current conversion power panel is the PWM controller unit with PFC function, and it mainly carries out power transfer; Convert alternating current into needed direct current, with the driving LED load; Said output rectification filtering power plate to reduce the ripple of direct current output, obtains level and smooth electric current for output rectification filtering unit, its direct current with conversion carries out rectifying and wave-filtering, to improve illumination effect, improves the whole lamp life-span.
Limit as another kind, the quantity of described thin copper post is no less than two.
The utility model adopts the beneficial effect of above technical scheme to be: owing to adopt contact pin to be fixed on the mode on the power panel; Saved with his mode need be between power panel and the lamp holder contact pin step of bonding wire; Simplified technology; Improve production efficiency, avoided because of the not firm short circuit that causes of solder joint or open circuit, improved the reliability that is electrically connected.Adopt the range upon range of structure of circular power panel simultaneously, made full use of the lamp holder cylindrical space, need not to take the space of lamp luminescence part, saved material cost, because power supply separates with luminous component, make the luminous layout of fluorescent tube more even, illumination effect is better.And adopt three layers of power panel range upon range of, can be complete on the power panel load each functional module of power supply, improved the performance of power supply, guaranteed the operate as normal of led chip, the service life of having improved fluorescent tube.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure, 1 lamp holder, 2 jacks, 3 input rectifying filtered electrical source plates, 4 contact pins, 5 current conversion power panels, 6 output rectification filtering power plates, 7 thin copper posts.
The specific embodiment
As shown in Figure 1, the utility model includes 5, one output of 3, one current conversion power panels of 1, one input rectifying filtered electrical of lamp holder source plate rectification filtering power plate 6, and two jacks 2 are arranged on the described lamp holder, is positioned at the centre position of lamp holder 1; Lamp holder 1 is installed together with the fluorescent tube radiator; Have on the described input rectifying filtered electrical source plate 3 with lamp holder 1 on jack 2 corresponding two contact pins 4, it can pass jack 2 and be installed on the lamp holder 1; Be fixedly connected by two thin copper posts 7 between described input rectifying filtered electrical source plate 3, current conversion power panel 5 and the output rectification filtering power plate 6; Connection between each circuit board then connects realization through lead.Described input rectifying filtered electrical source plate 3 is the unit of EMI rectifying and wave-filtering function; The PWM controller unit of said current conversion power panel 5 for having the PFC function; It mainly carries out power transfer, converts alternating current into needed direct current, with the driving LED load; Said output rectification filtering power plate 6 to reduce the ripple of direct current output, obtains level and smooth electric current for output rectification filtering unit, its direct current with conversion carries out rectifying and wave-filtering, to improve illumination effect, improves the whole lamp life-span.
The utility model can only be installed in fluorescent tube one end, also can two ends all be installed by this power supply, and it connects lead can be according to the practical situations transform length.
The above-mentioned specific embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as the technology contents essence of being made according to the disclosed technical scheme of this patent is identical or any change or the modification that are equal to, all fall into the scope that this patent comprises.
