Description

description

Field of the Invention The present invention relates to a light emitting diode (LED) tube lamp assembly.

Background of the Invention The use of LED chips for lighting applications is currently increasing. Due to their high efficiency and their low thermal performance compared to filament lamps energy can be saved in particular. Starting with quite specific designs for specific applications, more and more designs are becoming available for use in common and even existing electrical lighting installations with standardized bulb sockets, such as E22 or E26, or sockets such as T5 or T8 for fluorescent tubes. Many of these designs use COB (Chip On Board) modules with LED chips bonded to a printed circuit board (PCB). As a result, many chips can be arranged in a small space, where they produce high luminous fluxes together.

Summary of the Invention An object of the present invention is to provide an LED tube lamp assembly that can be used in common and even existing lighting installations with fluorescent tubes that are easy to assemble yet robust, complete automation of manufacture, or at least minimizing manufacturing overhead and scalability. These objects are achieved by an LED tube lamp assembly as defined in the independent claim. Accordingly, the LED tube lamp assembly according to the invention comprises: a tube housing which is at least partially translucent and has a cross-section which is circumferentially closed and constant in a longitudinal direction; a circuit board assembly provided with contact surfaces and LED chips and inserted in the longitudinal direction in the tube housing; and two side cap assemblies provided with external contacts for enabling the LED tube light assembly to be electrically connected to an electrical power supply and internal contacts for electrically connecting the external contacts to the contact surfaces of the printed circuit board assembly and inserted at least partially longitudinally into the tube housing are; and wherein the inner contacts are adapted to slidably contact the contact surfaces of the circuit board assembly when the side cap assemblies are inserted at least partially longitudinally into the tube housing.

The invention achieves the following advantages: The LED tube lamp assembly consists essentially of only four main components, namely the tube housing, the printed circuit board assembly and the two side cap assemblies, which can be manufactured independently and effectively assembled longitudinally by a fully automated process. Due solely to and during the partial insertion of the side cap assemblies into the tube housing, the inner contacts of the side cap assemblies come into electrical contact with the contact surfaces of the printed circuit board assembly. An additional contact agent or even an additional step of contacting is therefore not required. The tubular housing, because of its constant longitudinal cross-section, can be manufactured in an endless extrusion process, whereby its length, which also defines the overall length of the LED tube lamp assembly, can be freely selected by cutting. Characterized in that the cross-section of the tube housing is closed in the circumferential direction, the tube housing may be stable and self-supporting, without the need for additional reinforcement, and has no openings except for its open ends, which would have to be closed.

Preferred embodiments will be apparent from the dependent claims and the description. The individual embodiments may be used independently or differently combined with each other, depending on whether a particular advantage of a particular embodiment or a combination of embodiments is required in a particular case.

According to a first advantageous embodiment of the LED tube lamp assembly, the tube housing on a flat rear wall, which forms part of the preferably nearly rectangular cross-section, wherein the circuit board assembly is disposed almost adjacent to and parallel to such a flat rear wall. Thereby, the LED tube lamp assembly can be constructed with a small cross section, thereby avoiding hollow, wasted space.

In a further preferred embodiment, the tube housing has two longitudinally extending inner notches, which face each other and with which the circuit board assembly is engaged.

The two notches can be provided in a simple manner by appropriately forming the cross section of the tube housing. In particular, the two interior notches engaging the circuit board assembly may fix the circuit board assembly in the tube housing and preferably define its position parallel to the planar back wall. The tube housing and the circuit board assembly thus engaged may also further stabilize each other.

The tube housing may have two longitudinally extending, corresponding to the inner notches first Aussen sen ribs, which arise automatically when the wall thickness of the tube housing is substantially uniform.

The two outer ribs can be used with advantage for mounting the LED tube lamp assembly to a support structure. For this purpose, the LED tube lamp assembly may further comprise at least one mounting bracket with two snap arms for engagement with the first outer ribs and a connecting part between the snap arms.

The flat rear wall may be provided with second, extending in the longitudinal direction of the outer ribs. Such ribs could add rigidity to the tube housing and could help maintain the planar back wall at a defined distance from a support structure to which the LED tube light assembly can be mounted.

The circuit board assembly can be fixed by the two side cap assemblies in the tube housing against displacement in the longitudinal direction. As a result, such a fixation can be achieved without any further means solely by the at least partial insertion of the two side cap arrangements into the tube housing.

The contact surfaces are preferably planar portions which are located at end portions of the printed circuit board assembly. Such flat areas can be provided on the circuit board assembly without additional effort and can be easily and effectively contacted by suitably formed inner contacts of the side cap assemblies, as will be explained in more detail below.

The fluorescent tube lamps of the prior art are usually provided with a pair of external contacts at each end which allow them to be electrically connected in series with an igniter. Although LED chips do not require an igniter, providing pairs of external contacts would allow the LED tube lamp assemblies of the invention to be used even in existing common socket installations, such as T5 or T8, as a replacement for conventional fluorescent lamps. In order for the LED tube lamp assemblies of the invention to be used without regard to their orientation, the inner contacts and the contact surfaces should also be provided in pairs. In this case, the external contacts may be appropriate and connected by simple means with the circuit board assembly.

LED chips of the kind that are preferably used for the inventive LED tube lamp assembly, require a low voltage and can not be connected directly to a mains power supply with significantly higher voltage. In addition, to avoid the need for externally providing voltage conversion means, the circuit board assembly may be provided with electronic devices that include at least one integrated circuit for supplying electrical power from a utility power supply to the LED chips.

In at least partial insertion of the side cap assemblies in the longitudinal direction, the end portions of the tube housing can be clamped so that an interference fit between the substrate and bare areas is made. Therefore, additional attachment means for securing the side cap assemblies in the tube housing may be omitted.

Since this is common in many fluorescent tube lamps, the outer contacts of the side cap assemblies may have terminal pins projecting outwardly in the longitudinal direction. Such pins may be adapted to fit in common sockets, such as in particular T5 or T8. In this case, the LED tube lamp assembly of the present invention may even be used as a replacement for common fluorescent lamp lamps of existing installations.

Essentially, the same applies to an embodiment of an LED tube lamp assembly according to the invention, in which the outer contacts of one of the side cap assemblies plug-like outer contacts, and in which the outer contacts of the other side cap assembly are socket-like outer contacts, the male and the female outer contacts to are designed to be connected by plugging in the longitudinal direction.

For easy and secure contact making provided on the circuit board assembly contact surfaces alone in the at least partial insertion of the Seitenkappenanordnungen in the tube housing, especially in the case where such contact surfaces are flat and located at end portions of the circuit board assembly, the inner contacts of the side cap assemblies be spring-like sliding contacts. The spring-like sliding contacts can also be separated from each other by a projecting between them approach and guided in each case deflection.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Figs. 1 to 4 show a first embodiment of a LED tube lamp assembly 1 according to the present invention.

In Fig. 1a, the tube lamp assembly 1 in an axial direction X, which is characterized by a double arrow, pulled apart. Shown are four major components that are separate but available for assembly by relative movement only in the longitudinal direction X. The assembly 1 includes a tube housing 10, a circuit board assembly 20 and two side cap assemblies 30. The side cap assemblies 30 are identical in this embodiment.

The tubular housing 10 has, as shown in Fig. 1b, a cross section which is closed in the circumferential direction and in the longitudinal direction X is constant. The cross section is nearly rectangular with a width W and a height H. The width W is slightly greater than the height H. The length L in the longitudinal direction X is much larger than both the

Width W and the height H. As part of the nearly rectangular cross-section, the tube housing 10 has a flat rear wall 11, two slightly curved side walls 12 and a slightly curved front wall 13. The tube housing 10, in particular the front wall 13, is at least partially translucent, i. transparent or translucent. The back wall does not have to be translucent as well. Two inner notches 14 extend in the longitudinal direction X on the side walls 12, adjacent to the flat rear wall 11. Due to the fact that the thickness of at least the side walls 12 is nearly uniform, on the side walls 12, two first outer ribs 15, which are in accordance with the inner grooves 14 also extend in the longitudinal direction. The flat rear wall 11 is further provided with two second outer ribs 16, which also extend in the longitudinal direction.

The circuit board assembly 20 includes a circuit board 21 provided with a plurality of LED chips 22 arranged in a row. The circuit board assembly 21 is further provided with electronic devices 23 that include at least one integrated circuit for supplying electrical power from a utility power supply to the LED chips 22. At its two end portions 25, the circuit board assembly 20 is also provided in each case with a pair of planar contact surfaces 24. Other planar contact surfaces and tracks on the circuit board 21 for electrically connecting the LED chips 22 and the electronic devices 23 are not shown, but should be understood as being of course intended.

In this first embodiment, the two side cap assemblies 30, of which in Figs. 2a to 2e different views are shown, as already mentioned, identical. Only one of them will be described below. The side cap assembly 30 is provided with a pair of external contacts 31 to allow the LED tube lamp assembly 1 to be electrically connected to an electrical power supply (not shown). The outer contacts 31 are formed as terminal pins that project outwardly in the longitudinal direction X to be compatible with standard sockets, such as T5 in particular. The side cap assembly 30 is further provided with a pair of inner contacts 32 for electrically connecting the outer contacts 31 to the contact regions 24 on the printed circuit board 21. The inner contacts 32 are realized as spring-like sliding contacts. The side cap assembly 30 further includes a planar wall portion 33 in which the outer contacts 31 and the inner contacts 32 are fastened together and from which a tubular portion 34 which surrounds the inner contacts 32 protrudes in the longitudinal direction. The flat wall portion 33 extends to form a ring 35 on all sides beyond the tubular portion 34 addition. From the flat wall portion 33 further protrudes between the inner contacts 32, a projection 36 as a release agent between these contacts. The approach also leads the contacts in their deflection.

In Figs. 3a to 3e different views of the LED tube lamp assembly 1 of Fig. 1a are shown in the assembled state. FIGS. 4a to 4e also show details of the LED tube lamp arrangement of FIG. 1a in the assembled state. To assemble its four main components, the printed circuit board assembly 20 is inserted in the longitudinal direction X in the tube housing 10 in a first step, so that the circuit board 21 engages with its outer edges 21 a and 21 b in the two notches 14. Characterized the circuit board assembly 20 is arranged with only a small lateral tolerance parallel to the flat rear wall 11 and preferably even in contact with this. Of course, the circuit board assembly is inserted into the tube housing 10 so that the light emitted from the LED chips 22 is mainly emitted toward the front wall 13.

In a second and third step, the two side cap assemblies 30 are also inserted longitudinally into the tube housing 10 at both ends thereof. The tubular portions 34 are designed to closely fit within the tube housing 10 such that the end portions thereof are clamped and an interference fit is achieved by which the side cap assemblies 30 are mounted in the tube housing 10 without the need for other means. Since the collars 35 are flush with the front ends of the tube housing 10, insertion of the side cap assemblies 30 is limited to partial insertion. The outer contours of the collar 35 also correspond to the outer contour of the cross section of the tubular housing 10th

When inserting the two side cap assemblies 30, the inner contacts 32, which are realized as spring-like sliding contacts, slidingly come into electrical contact with the contact surfaces of the printed circuit board assembly, as best seen in Figs. 3b and 3d. There are no further means or process steps required to make such contact.

The length of the circuit board 21 of the printed circuit board assembly 20 is chosen so that it fits almost exactly between the two Seitenkappenanordnungen 30 in the tube housing 10. In the assembled state, which is shown in Figs. 4a to 4d, the circuit board assembly 20 is thus fixed by the two side cap assemblies 30 in the tube housing 10 in the longitudinal direction.

5 and 6 show a second embodiment of an LED tube lamp assembly 1 according to the present invention. In contrast to the first embodiment, the terminal pins of the first contacts 31 of the side cap assemblies 30 are separated by a greater distance than in the first embodiment. This also applies to the spring-like second contacts 32. As a result, the contacts 31 with standard versions, in particular T8 compatible.

In the second embodiment, the tubular portions 34 of the side cap assemblies 30 also differ slightly from those portions of the first embodiment, as can be seen by comparing Figures 2c to 2e with Figures 6c to 6e. In the second embodiment, no tongue-like element 36 is provided, but instead recesses 37.

Now, a third embodiment with reference to Figs. 7 to 13 will be explained. In this embodiment, the two side cap assemblies differ from each other. The outer contacts of one of the side-cap assemblies, designated 30m in FIG. 7, are male-type outer contacts 31m, while the outer contacts of the other side-cap assembly, designated 30f in FIG. 7, are female-type outer contacts 31f. Both the male-type outer contacts 31m and the female-type outer contacts 31f are configured so that they can be connected by being inserted in the longitudinal direction X.

In contrast, LED tube lamp assemblies according to the first or second embodiment of the invention, which are provided with projecting pin-like, to common T5 or T8 versions compatible outer contacts 31, used as a whole transversely to its longitudinal extent between two such versions, wherein their projecting terminal pins 31 each engage in a slot in a rotatable part of the sockets. The LED tube lamp assemblies are then electrically connected by rotation about their longitudinal extension and mechanically secured. In the male and female outer contacts 31m and 31f of the third embodiment, mechanical fasteners may be required in addition to the pluggable electrical contact means.

Fig. 7 shows the LED tube lamp assembly according to the third embodiment of the invention together with two mounting brackets 40 as additional mechanical fastening means. The mounting brackets 40 each have two snap arms 41 for engagement with the first outer ribs 15 of the tube housing 10 and a connecting part 42 between the snap arms. A screw hole 43 in the connecting part 42 allows attachment of the mounting brackets 40 by means of a screw and optionally a wall plug to a supporting structure.

Figs. 8a to 8e show the LED tube lamp assembly of Fig. 7 in the assembled state together with two mounting brackets 40 which are snapped onto the tube housing. Further details of the holders 40 can be seen in FIGS. 9a to 9c.

Various views of the side cap assembly 30m of FIG. 7 with plug-like outer contacts 31m are shown in FIGS. 10a-10e. FIGS. 11a to 11e show different views of the side cap assembly 30f of FIG. 7 with bushing-like outer contacts 31f. Figs. 12a to 12d and 13a to 13d show details of the LED tube lamp assembly of Fig. 7 in the assembled state. Apart from the male and female outer contacts 31m and 31f, the configuration of the side cap assemblies 30m and 30f of the third embodiment is almost identical and corresponds to the configuration of the side cap assemblies 30 of the first embodiment. In particular, the inner contacts 32 are in turn formed here as spring-like sliding contacts and it is a surrounding the inner contacts tubular portion 34 is provided, which is adapted to fit tightly into the tube housing 10. Both side cap assemblies 30m and 30f are thus adapted to be inserted in the longitudinal direction X in the tube housing 10 and secured therein by a press fit.

In all three embodiments described, the same tube housing 10 and the same circuit board assembly 20 may be used. In order to be compatible with the pitch of the inner contacts 32 different in the first and second embodiments, the contact areas 24 and the circuit board 21 are made large enough to respectively fit to the respective positions of the inner contacts 32.
