Abstract
A light-emitting diode (LED) lamp tube capable of directly replacing a traditional T5 lamp tube comprises a T5 LED lamp tube, an LED driver and lamp pins located at two ends of the T5 LED lamp tube. The LED driver is located at one end of the T5LED lamp tube and is formed by a micro integrated LED driver capable of being directly connected with the electric supply, and the LED driver is located in one lamp pin at one end of the T5 LED lamp tube. The length and the diameter of the lamp pin are identical with those of a fluorescent T5 lamp tube. The LED lamp tube adopts a micro integrated LED driving chip which ensures that the whole LED driver can be installed in the pin of the traditional T5 lamp tube without affecting length of the T5 LED lamp tube. Therefore, the lamp tube is convenient to replace, and lighting range of the T5 LED lamp tube is not affected. In addition, the LED lamp tube adopts an external refrigerating chip, enables the refrigerating chip to obtain a power supply from the LED driver, strengthens radiating effect of the LED driver, enables the LED driver to be smaller in size and is suitable for the T5 LED lamp tube.
Description
Technical field
The present invention relates to a kind of can direct substitution the LED fluorescent tube of tradition T5 fluorescent tube.
Background technology
The energy-saving effect of LED lamp is well-known, flourish along with the LED light fixture, the batch of LED use and with being replaced into for the illumination market main flow of conventional lamp, also produced during this period the problem of more Products Compatibility.Because the external diameter of the straight type lamp of existing T5 fluorescent tube is thin (diameter 15.875mm) too, the LED driving power can't be similar to T8(diameter 25.4mm at all) and T10(diameter 31.8mm) threading fluorescent tube inside.So, present T5LED lamp on the market, the integrated structure of lamp body and lampshade mostly, such as the T5 of the disclosed integral LED of Chinese patent literature CN201258516U pipe, the T5 pipe of integral LED when upgrading, need to fluorescent tube and lamp bracket complete removal with former fluorescent lamp after, just can load onto the T5 pipe of integral LED, time-consuming, cost is high, affects the popularization of this T5 light fixture; Also having a kind of transformation to the T5 light fixture is exactly that LED fluorescent tube part only fills the luminous wick of LED, and the power drives part arranges separately in addition, replaces original rectifier, and this T5 type LED fluorescent tube is same to be existed when upgrading, time-consuming problem.
In order to address the above problem, Chinese patent literature CN102230585A discloses a kind of LED fluorescent tube of alternative T5 fluorescent tube, it is that the LED driver module is divided into two parts, a part is power module, one is to exchange to drive chip, drive on the fixing pcb board with the LED light emitting diode of chip exchanging, and power unit still is fixed in the T5 lamp tube type village, the greatest problem that this design exists be since the caliber of T5 too the small power supply module and exchange the driving core and the LED luminescence chip from too close to, and so that power module drives the heat that core produces with exchanging, be not easy in time to leave very, and affect the service life of LED light emitting diode; And this design if any part in LED light emitting diode and the led drive circuit is damaged, all needs whole replacings, so that customer using cost is too high; Chinese patent literature CN102635804A discloses a kind of LED fluorescent tube of alternative T5 fluorescent tube, it is on the pcb board with the LED light emitting diode that power module is fixing, realization is to the driving of LED light emitting diode, the LED fluorescent tube of this alternative T5 fluorescent tube exist equally power module and LED luminescence chip from too close to, and so that the heat that power module produces, be not easy in time to leave very, and affect the service life of LED light emitting diode; And this design if any part in LED light emitting diode and the led drive circuit is damaged, all needs whole replacings, so that the too high problem of customer using cost.
Chinese patent literature CN202074301U discloses a kind of plug-and-pull driver type LED fluorescent lamp, and bag is that driver is established at one end in the lamp holder, and is connected with the fluorescent tube plug.Like this, temperature between LED fluorescent tube and the driver can not produced influence each other, can improve the service life of LED fluorescent tube and driver; And driver (lamp holder) and fluorescent tube socket connection, easy accessibility, if wherein any part is damaged, all can be conveniently replaced, save use cost.This plug-and-pull driver type LED fluorescent lamp that driver is arranged at LED fluorescent tube one end, theoretically, although, can be suitable for T5 LED fluorescent tube, or the less LED fluorescent tube of caliber, such as T4, still, in the practical application, because existing driver all comprises step-down power transformation device and high power capacitor, because the existence of these electric elements, so with the end of driver design at the LED fluorescent tube, mostly be only suitable for the thicker LED fluorescent tube of caliber, such as T8 or T10, for the LED fluorescent tube than pipe with small pipe diameter, such as T5 or T4 fluorescent tube, not too suitable, because, if driver is arranged on LED fluorescent tube one end, because T5 or T4LED fluorescent tube caliber are too little, just must add the length of elongated drive, the caliber that adapts to the LED fluorescent tube, so, can cause LED fluorescent tube length to shorten, and affect the lighting area of LED light fixture.In addition, for T5 or T4 fluorescent tube, if adopt the technology that driver is arranged on LED fluorescent tube one end, because the restriction of driver diameter is (for attractive in appearance, the diameter of driver generally equals the diameter of LED fluorescent tube), the area of dissipation of driver also is restricted, and affects the heat radiation of driver, and then affects the life-span of driver.
