Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In the present application, the directional term "longitudinal" refers to the axial direction of the lighting module 1 (the direction of arrow X in fig. 1), and the directional term "lateral" refers to the direction perpendicular to the "longitudinal" direction.

Fig. 1 schematically shows an overall view of a lighting module 1 according to an embodiment of the present application. Fig. 2 and 3 show the individual components of the lighting module 1, respectively. As shown in fig. 1, 2 and 3, the lighting module 1 includes: the lamp comprises a base 100, a cylindrical light source 200, a lampshade 300 and a driving module 400. The base 100 has an inner cavity 110 for carrying the driving module 400. The tube light source 200 penetrates in the longitudinal direction, and the first end 201 of the tube light source 200 is fitted on the base 100. The shape of the lamp cover 300 is adapted to the tube-shaped light source 200 to fit the outer side of the tube-shaped light source 200, and the first end 301 of the lamp cover 300 is engaged with the base 100.

The lighting module 1 of the present application uses the cylindrical light source 200. On the whole, the lighting module 1 is cylindrical, can uniformly emit light at 360 degrees, has unique lighting effect, and can be used for the requirement of personalized lighting.

When the tube light source 200 uses a light emitting LED as a light source module, the driving module 400 is an LED driving module. The structure of the driving module 400 is well known to those skilled in the art and will not be described herein.

The individual components of the lighting module 1 are described separately below.

Fig. 4 schematically shows a perspective view of the base 100 of the lighting module 1. As shown in fig. 4, the chassis 100 is a generally cylindrical structure having an interior cavity 101. The cavity 101 is closed at one end and open at the other end. The lamp set 100 may include two annular portions, i.e., a first portion 110 and a second portion 130, in communication in the longitudinal direction. Such that the first portion 110 and the second portion 130 together comprise the lumen 101. Preferably, the first portion 110 and the second portion 130 are integrally formed, such as by injection molding with a clear plastic; it is of course also possible to form them separately and then to assemble them together.

Drive module 400 is carried within interior cavity 101 and extends longitudinally outward from interior cavity 101 into interior 210 of tube light source 200 (shown in fig. 3). As a whole, the inner cavity 101 of the chassis 100 and the interior 210 of the tubular light source 200 (or the heat sink 202 of the tubular light source 200) are combined into a through space, and the driving module 400 is located in the through space. This contributes to increase the light emitting area of the lighting module 1 and thus improves the use experience of the lighting module 1. Preferably, the base 100 is made of a transparent material. For example, a plastic material such as transparent Polyethylene (PE) or transparent polypropylene (PP) may be used. This may further enhance the degree to which the lamp shade 300 is illuminated, thereby further improving the use experience of the lighting module 1.

In a specific embodiment, a conductive interface 131 is disposed on the second portion 130 of the base 100, and the driving module 400 is electrically connected to the conductive interface 131 to drive the tubular light source 200 to emit light. In another embodiment, as shown in fig. 1, 2 and 3, the conductive interface 131 may be a standard metal screw to facilitate the installation of the lighting module 1. The conductive interface 131 may be riveted to the second portion 130 of the base 100. Two slots 102 are formed in the inner cavity 101, and the driving module 400 is inserted into the slots 102 and electrically connected to the conductive interface 131.

In order to mount the cylindrical light source 200 on the base 100 (or the first part 110), the first part 110 configures an annular baffle 111 extending longitudinally at an end thereof, a plurality of first fixing tabs 112 are provided circumferentially inside the annular baffle 111, and a first gap 113 is formed radially between the first fixing tabs 112 and the annular baffle 111. The first end 201 of the tubular light source 200 is inserted into the first gap 113, preferably with an interference fit. Thus, the cylindrical light source 200 can be stably mounted on the base 100 by the limit action of the first fixing tabs 112 and the annular baffle 111. In a particular embodiment, the first fixing tabs 112 are four in number and are evenly distributed in the circumferential direction. The inventors found that this can fix the cylindrical light source 200 more stably. In order to further stabilize the tubular light source 200, the tubular light source 200 is fixed in the first gap 113 with an adhesive.

The cylindrical light source 200 includes a cylindrical heat sink 202 (see fig. 6) longitudinally penetrating therethrough and a light source module 203 (see fig. 7) mounted on an outer surface of the heat sink 202. In this case, the heat sink 202 is caught on the base 100, for example, in the first gap 113. In addition, the driving module 400 extends into the heat sink 202 and is electrically connected with the light source module 203.

The heat sink 202 may be bent from a flexible aluminum sheet. The aluminum plate has good heat conduction performance, can rapidly guide heat generated by the light source module 203 into the inner part 210 of the heat sink 202, and is further carried by air flow passing through the inner part 210 of the heat sink 202, so that heat dissipation is realized. The heat dissipation path of the airflow will be described in detail below. It should be understood that the heat sink 202 may be made of other materials, and will not be described herein. In addition, the inner portion 210 of the heat sink 202 may also be configured or arranged with other structures that facilitate heat dissipation or gas flow, such as heat dissipation fins, and will not be described further herein.

The light source module 203 may include a flexible substrate 204 (e.g., a flexible circuit board) and a light source 205 (e.g., a light emitting LED) disposed on the flexible substrate. The flexible substrate 204 is bent to conform to the heat spreader 202 and fixed on the heat spreader 202. Thus, the light source module 203 can be conveniently bent and fixed on the cylindrical heat sink 202, so that the lighting module 1 can emit light in 360 degrees. In addition, the light source module 203 is also inserted into the first gap 113, which can reduce the probability of the light source module 203 peeling off from the heat sink 202, tilting, and other adverse conditions.

In another embodiment, the tube light source 200 or the light source module 203 is provided with a transverse annular top plate 207 at a second end 206 thereof opposite to the first end 201 in the longitudinal direction thereof (as shown in fig. 2 and 7). The light source 205 is also disposed on the ring-shaped top plate 207, thereby further improving the effect of light emission of the lighting module 1. The annular top plate 206 has a central aperture 208 in communication with the interior 210 of the cylindrical light source 200, the central aperture 208 serving to form a heat dissipation path for the air flow, as will be described below.

Returning to fig. 3, the lampshade 300 is sleeved outside the cylindrical light source 200, and the first end 301 of the lampshade 300 is engaged with the base 100. The coupling structure of the lamp cover 300 and the base 100 will be described. As shown in fig. 8 and 10, elastic claws 115 are formed on the radially outer surface of the ring shutter 111, and the elastic claws 115 can be compressed or sprung in the radial direction. A radially through-going locking groove 302 is formed at a first end 301 of the lamp housing 300. Thus, during assembly, the lamp housing 300 is longitudinally sleeved onto the cylindrical light source 200 and the resilient fingers 115 are compressed radially inward; when the resilient fingers 115 are aligned with the slots 302, they spring radially outward and snap into the slots 302. Thereby, the lamp cover 300 is stably mounted on the base 100.

It should be understood that the resilient latch 115 may be circumferentially aligned with the first securing tab 112 or may be misaligned as may be determined by the manufacturing requirements of the chassis 100.

To further stabilize the mounting of the lamp shade 300, there is also a longitudinally extending second securing tab 116 on the first portion 110 of the base 100, the second securing tab 116 being radially outward of the resilient catch 115, and a radial second gap 117 existing between the second securing tab 116 and the resilient catch 115. The first end 301 of the lamp cap 300 is inserted into the second gap 117, and a radially non-through engagement groove 316 is formed on the outer surface of the first end 301 of the lamp cap 301, with which engagement groove 316 the second fixing tab 116 engages. Thus, the rotation of the lamp housing 300 in the circumferential direction is prevented by the limit action of the second fixing tab 116 and the engaging groove 316, so that the installation of the lamp housing 300 is more stable.

In one particular embodiment (as shown in fig. 8), the outer surface of the first end 301 of the lamp housing 300 is configured with a circumferential reduced thickness ring 317. The engagement slot 316 is a contoured area of the reduced thickness ring 317, and the shape of the second securing tab 116 matches the shape of the engagement slot 316. In this structure, since the contour of the engagement groove 316 is different from the contour of the remaining portion of the thickness reducing ring 317, the lamp cover 300 will not be circumferentially rotated after the second fixing tab 116 is engaged with the engagement groove 316, thereby making the installation of the lamp cover 300 more stable.

It should be understood that the second securing tab 116 may be circumferentially aligned with the resilient latch 115 or may be misaligned as may be determined by the manufacturing requirements of the chassis 100. When possible, the second fixing tab 116 is circumferentially offset from the elastic claw 115, so that excessive absorption of light emitted from the cylindrical light source 200 (the second fixing tab 116 and the elastic claw 115) at the same position of the lamp housing 300 at the first end can be avoided, thereby contributing to the uniformity of illumination of the lamp housing 300 at the first end 301, and further contributing to improving the experience of the lighting module 1.

The heat dissipation path within the lighting module 1 is described below.

As shown in FIG. 4, first louvers 118 are provided in the first portion 110 of the base 100 at a position longitudinally offset from the annular baffle 111 (as shown in FIG. 5). The first heat dissipation hole 118 communicates with the inner cavity 101 of the base 100. As shown in fig. 9, a second heat dissipation hole 321 is formed at a second end 320 of the lamp housing 300 opposite to the first end 301 thereof. The second heat emission hole 321 communicates with the interior 210 of the cylindrical light source 200 (or the heat sink 202) through the center hole 208 of the annular top plate 207. Thus, the first heat dissipation hole 118, the inner cavity 101 of the base 100, the interior 210 of the cylindrical light source 200, and the second heat dissipation hole 321 are sequentially communicated to form the heat dissipation path 2. The second heat dissipation hole 321 may be a single hole, or may be formed by combining a plurality of small holes (as shown in fig. 9).

As shown in fig. 11, when the lighting module 1 is used, heat generated by the light source module 203 and/or the driving module 400 is transferred to the interior 210 of the tubular light source 200 (or the heat sink 202). The hot air will leave the lighting module 1 through the second heat dissipating holes 321, and the cold air in the environment will enter the inner cavity 101 of the base 100 through the first heat dissipating holes 118, and then flow into the interior 210 of the tubular light source 200 (or the heat sink 202), and cool the light source module 203 and/or the driving module 400 again. Thus, cold air in the environment automatically enters the lighting module 1 along the heat dissipation path 2 and exits the lighting module 1 after being heated, thereby cooling the light source module 203 and/or the driving module 400. This contributes to extending the service life of the lighting module 1.

In another embodiment (as shown in fig. 9), the inner surface of the lamp housing 300 is configured with an annular wall 322 around the second heat dissipation hole 321, the annular wall 322 extending longitudinally and abutting against the central hole 208 through the annular top plate 207. In this way, the annular wall 322 separates the heat dissipation path 2 from the space 3 between the cylindrical light source 200 (or the light source module 203) and the lamp cover 300, so as to prevent the pollutants in the environment from entering the space 3 and the adverse effect of the lighting module 1.

As also shown in fig. 9, longitudinally extending support ribs 323 are configured around the annular wall 322. The support rib 323 abuts against the annular top plate 207. Thus, the support ribs 323 apply a pressing force to the light source module 203 (or the tube light source 200) in the longitudinal direction, so that the tube light source 200 is more stably mounted on the base 100. The number of the support ribs 323 may be plural and spaced apart.

The above description is only an example of the present application and is not intended to limit the present application. Various modifications and changes may occur to those skilled in the art.
