Description

Technical Field

[0001] Various embodiments generally relate to a lamp for displaying multi-color lighting effects. In particular, various embodiments generally relate to an intelligent lamp for displaying various multi-color lighting effects in response to control signals received by the intelligent lamp. Background Art

[0002] Conventionally, a lamp provides lighting in order to illuminate a room and / or set the atmosphere of a room. Typically, different bulb colors can be selected and installed in the lamp depending on the location and purpose of the lamp. Typically, once the bulb is installed and the lamp is placed in the desired location, the bulb is rarely changed and / or the lamp is rarely moved to change the type of lighting and / or atmosphere. With the advancement of technology, people are considering expanding the purpose and function of the lamp to more than just lighting the room. For example, recently, smart lights have been developed that can switch between different colors based on a set schedule or scene options, or synchronize with songs, movies, video games, weather, etc., or use it for visual cues to remind you to remember your schedule or for visual cues for safety. However, such smart lights can only switch from one color of lighting to another color of lighting. Therefore, such smart lights are limited to displaying only one monochrome lighting at a time, and are not enough to effectively meet the ever-expanding usage needs of users.

[0003] Therefore, a more efficient and versatile lamp is needed to address the ever-expanding usage requirements of users for lamps. Summary of the invention

According to various embodiments, the light emitting module 110 may be configured to illuminate the lamp 100 to display a multi-color lighting effect. According to various embodiments, the light emitting module 110 may be configured to optimize the change in color in the emitted light so as to effectively and efficiently illuminate the lamp 100 to display a multi-color lighting effect.

[0055] According to various embodiments, the lamp 100 may include a hollow lampshade 140 mounted on the light emitting module 110, so that the emitted light can be projected on the hollow lampshade 140 to illuminate the hollow lampshade 140 for displaying a multi-color lighting effect. Therefore, the light emitting module 110 can be inserted into the hollow lampshade 140. According to various embodiments, the light emitting module 110 can emit light to the hollow lampshade 140, so that the hollow lampshade 140 can display multiple areas of different colors on the hollow lampshade 140, thereby each area can be independently illuminated with a desired color. Each area of ​​the hollow lampshade 140 can be a zone or portion of the hollow lampshade, without any physical demarcation or separation or boundary on the hollow lampshade 140 to delineate different areas. Therefore, the light emitting module 110 can be controlled to illuminate the hollow lampshade 140 to display multiple areas of different colors in order to produce different visual lighting patterns, spectrums, animations, rhythms (including circadian rhythms) and / or effects. Therefore, a multi-color lighting effect can be achieved by using the light emitting module 110 to illuminate different areas of the hollow lampshade 140 differently from each other. According to various embodiments, the hollow lampshade 140 can have various shapes, including but not limited to spherical, cylindrical, conical, truncated conical, drum, barrel, cone, bell, or polygonal.

According to various embodiments, the hollow lampshade 140 can be made of a light diffusing material, including but not limited to plastic, acrylic, fabric or gel. Therefore, the hollow lampshade 140 can be used as a light diffuser to diffuse or scatter the light from the light emitting module 110.

[0058] According to various embodiments, the light emitting module 110 may include a plurality of white light emitting elements 116. According to various embodiments, each white light emitting element 116 may be any suitable white light source, such as a cold white light source and / or a warm white light source. Warm white light may refer to white light having a correlated color temperature (CCT) of 1000 Kelvin to 4000 Kelvin, while cold white light may refer to white light having a CCT of 4000 Kelvin to 7000 Kelvin. According to various embodiments, each white light emitting element 116 may include, but is not limited to, a light emitting diode (LED) or an organic light emitting diode (OLED) or a polymer light emitting diode (PLED) that emits white light.

In addition, the central axis 118 of the light emitting module 110 may be orthogonal to the lighting element mounting surface 114 of the base substrate 112. Therefore, the central axis 118 of the light emitting module 110 may be perpendicular to the lighting element mounting surface 114 of the base substrate 112 at the center of the circular arrangement of the plurality of white light emitting elements 116. Therefore, the central axis 118 of the light emitting module 110 may perpendicularly intersect the lighting element mounting surface 114 of the base substrate 112 at the center of the circular arrangement of the plurality of white light emitting elements 116. Therefore, the central axis 118 of the light emitting module 110 may serve as a common axis for the circular arrangement of the plurality of white light emitting elements 116 and the light emitting module 110.

Furthermore, the elongated support structure 122 may extend away from the mounting surface 114 of the base substrate 112 or protrude from the mounting surface 114 of the base substrate 112. Thus, the elongated support structure 122 may stand upright or extend upward from the mounting surface 114 of the base substrate 112 in a direction away from the mounting surface 114 of the base substrate 112. According to various embodiments, the elongated support structure 122 may be perpendicular to the mounting surface 114 of the base substrate 112 .

According to various embodiments, at least one row of red-green-blue light emitting elements 126 may be distributed along the length direction of the elongated support structure 122. Thus, the red-green-blue light emitting elements 126 of at least one row of red-green-blue light emitting elements 126 may form a straight line in the longitudinal direction of the elongated support structure 122. Thus, at least one row of red-green-blue light emitting elements 126 may be aligned with the longitudinal direction of the elongated support structure 122. According to various embodiments, the red-green-blue light emitting elements 126 may be longitudinally spaced apart from each other.

According to various embodiments, the light diffuser cover 150 may be in the form of, but is not limited to, a light diffuser plate, a light diffuser panel, a light diffuser sheet, a light diffuser dome, or a hemispherical light diffuser. According to various embodiments, the light diffuser cover 150 may be placed on top of a plurality of white light emitting elements 116 on the mounting surface 114 of the base substrate 112 of the light emitting module 110. Thus, the light diffuser cover 150 may diffuse or scatter light from a plurality of white light emitting elements 116 on the mounting surface 114 of the base substrate 112. Thus, light projected from a plurality of white light emitting elements 116 into the hollow lampshade 140 may be diffused or scattered. According to various embodiments, the light diffuser cover 150 may cover the plurality of white light emitting elements 116 such that the plurality of white light emitting elements 116 may be between the mounting surface 114 of the base substrate 112 and the light diffuser cover 150 .

[0065] According to various embodiments, the light diffuser cover 150 may include a through hole 152.

Therefore, the hollow lampshade 140 may form a housing around the elongated support structure 122 of the light emitting module 110 relative to the central axis 118. In addition, the base opening 142 of the hollow lampshade 140 and the base substrate 112 of the light emitting module 110 may be brought together so as to meet or connect or interact or contact. According to various embodiments, the base opening 142 of the hollow lampshade 140 may point to the base substrate 112 of the light emitting module 110. According to various embodiments, the rim 144 of the base opening 142 of the hollow lamp housing 140 may define a boundary surrounding the plurality of white light emitting elements 116, so that the plurality of white light emitting elements 116 may be able to illuminate the hollow lamp housing 140 from the base opening 142 of the hollow lamp housing 140. Therefore, the plurality of white light emitting elements 116 may be located within the boundary defined by the base opening 142 of the hollow lamp housing 140 so as to direct light into the hollow lamp housing 140. According to various embodiments, the light emitting module 110 may be inserted into the hollow lamp housing 140 through the base opening 142 of the hollow lamp housing 140. According to various embodiments, the elongated support structure 122 of the light emitting module 110 may be located inside the hollow lamp housing 140, and the base substrate 112 of the light emitting module 110 may be located at the base opening 142 of the hollow lamp housing 140.

[0067] According to various embodiments, each red-green-blue light emitting element 126 in at least one row of red-green-blue light emitting elements 126 may be individually controllable. Therefore, each red-green-blue light emitting element 126 may be independently controlled to light up with one color, so that different red-green-blue light emitting elements 126 may have different colors. According to various embodiments, each red-green-blue light emitting element 126 may be connected to a corresponding local microcontroller so that it can be individually controlled by sending a control signal to the corresponding local microcontroller. According to various embodiments, at least one row of red-green-blue light emitting elements 126 may include a strip of individually addressable red-green-blue LEDs, or a strip of individually addressable red-green-blue OLEDs, or a strip of individually addressable red-green-blue PLEDs. According to various embodiments, at least one row of red-green-blue light emitting elements 126 may be connected to a local microcontroller for individually controlling each red-green-blue light emitting element 126.

[0068] According to various embodiments, each row of the at least one row of red-green-blue light emitting elements 126 may be parallel to the central axis 118 of the light emitting module 110. According to various embodiments, each row of the at least one row of red-green-blue light emitting elements 126 may be supported by the elongated support structure 122 of the light emitting module 110 in a manner parallel to the central axis 118. According to various embodiments, each row of the at least one row of red-green-blue light emitting elements 126 may be perpendicular to the base substrate 112 of the light emitting module 110.

[0069] According to various embodiments, the lamp 100 may include two or more rows of red-green-blue-light emitting elements 126. Thus, the lamp 100 may include two, or three, or four, or five, or six, or seven, or eight, or more rows of red-green-blue-light emitting elements 126. According to various embodiments, the two or more rows of red-green-blue-light emitting elements 126 may be distributed circumferentially around the elongated support structure 122 of the light emitting module 110. Thus, each of the two or more rows of red-green-blue-light emitting elements 126 may be along a different longitudinal side of the elongated support structure 122. According to various embodiments, the two or more rows of red-green-blue-light emitting elements 126 may be angularly evenly spaced apart from each other relative to the central axis 118 of the light emitting module 110. For example, when there are two rows of red-green-blue light emitting elements 126, the two rows of red-green-blue light emitting elements 126 may be spaced 180° apart from each other relative to the central axis 118 of the light emitting module 110 so as to be along opposite sides of the elongated support structure 122. As another example, when there are four rows of red-green-blue light emitting elements 126, the four rows of red-green-blue light emitting elements 126 may be spaced 90° apart from each other relative to the central axis 118 of the light emitting module 110 so as to be along four longitudinal sides of the elongated support structure 122, which delimit the elongated support structure 122 into four equal quadrants. As yet another example, when there are eight rows of red-green-blue light emitting elements 126, the eight rows of red-green-blue light emitting elements 126 may be spaced 45° apart from each other relative to the central axis 118 of the light emitting module 110 so as to be along eight longitudinal sides of the elongated support structure 122, which delimit the elongated support structure 122 into eight equal quadrants.

[0070] According to various embodiments, the elongated support structure 122 of the light emitting module 110 may include a tubular wall structure 132. According to various embodiments, the tubular wall structure 132 may define a hollow passage 134 that extends longitudinally through the elongated support structure 122 along the central axis 118 of the light emitting module 110. Thus, the hollow passage 134 may extend through the elongated support structure 122 in a longitudinal direction or in a length direction. Furthermore, the tubular wall structure 132 may be aligned with the central axis 118 of the light emitting module 110 such that the central axis 118 of the light emitting module 110 may extend through the hollow passage 134. According to various embodiments, a centerline of the hollow passage 134 may coincide with the central axis 118 of the light emitting module 110 such that the central axis 118 may also be the longitudinal axis of the hollow passage 134.

[0071] According to various embodiments, the distal end 122b of the elongated support structure 122 distal from the base substrate 112 may include a channel opening 136 for the hollow channel 134. Thus, the channel opening 136 may provide access to the hollow channel 134 of the elongated support structure 122. Thus, the distal end 122b of the elongated support structure 122, which is furthest from the base substrate 122, may be opened for access to the hollow channel 134.

[0072] According to various embodiments, the elongated support structure 122 of the lighting module 110 may include 138 a plurality of heat sinks within the hollow channel 134. According to various embodiments, the plurality of heat sinks 138 may extend longitudinally along the inner surface 132a of the tubular wall 132 of the elongated support structure 122 and protrude inwardly from the inner surface 132a of the tubular wall 132 toward the central axis 118 of the lighting module 110. Thus, a heat sink base 138b of each heat sink 138 of the plurality of heat sinks 138 may be coupled to the inner surface 132a of the tubular wall 132 of the elongated support structure 122, and a heat sink tip 138a of each heat sink 138 of the plurality of heat sinks 138 (which is opposite to the heat sink base 138b) may be directed away from the inner surface 132a of the tubular wall 132.

[0073] According to various embodiments, each of the plurality of fins 138 can serve as an extended surface of the elongated support structure 122 to increase the rate of heat transfer to the environment by increasing the surface area for convection. Thus, heat generated by at least one row of red-green-blue light emitting elements 126 along the elongated support structure 122 can be transferred to the elongated support structure 122 and dissipated by the plurality of fins 138. According to various embodiments, at least one fin 138 within the hollow channel 134 can be aligned with a row of red-green-blue light emitting elements 126 on the exterior of the elongated support structure 122.

[0074] For example, Figure 2A , Figure 2B , Figure 5A and Figure 5B As shown, according to various embodiments, each of the plurality of heat sinks 138 may be a radial heat sink that protrudes radially inward from the inner surface 132a of the tubular wall 132 of the elongated support structure 122 toward the central axis 118 of the light emitting module 110. Therefore, each of the plurality of heat sinks 138 may protrude inward toward the central axis 118 of the light emitting module 110 in a direction along the radius of the hollow channel 134. According to various embodiments, the plurality of heat sinks 138 in the form of radial heat sinks may divide the hollow channel 134 of the elongated support structure 122 into a plurality of sectors. Therefore, each sector of the hollow channel 134 may be between two adjacent radial heat sinks. Therefore, each sector of the hollow channel 134 may expose two adjacent radial heat sinks to the air column between the two adjacent radial heat sinks for heat transfer, thereby cooling the two adjacent radial heat sinks.

[0075] According to various embodiments, the elongated support structure 122 of the light emitting module 110 may include an elongated hub element 139. According to various embodiments, the elongated hub element 139 may extend along the central axis 118 of the light emitting module 110. Thus, the elongated hub element 139 may be aligned with the central axis 118 of the light emitting module 110. According to various embodiments, the centerline of the elongated hub element 139 may coincide with the central axis 118 of the light emitting module 110, such that the central axis 118 may also be the longitudinal axis of the elongated hub element 139. According to various embodiments, the tubular wall 132 of the elongated support structure 122 and the elongated hub element 139 of the elongated support structure 122 may be coaxial, such that the tubular wall 132 and the elongated hub element 139 may be concentric with the tubular wall 132 surrounding the elongated hub element 139.

[0076] According to various embodiments, the fin tip 138a of each heat sink 138 of the plurality of heat sinks 138 may be coupled to the elongated hub element 139 or may be spaced apart from the elongated hub element 139. Thus, when the fin tip 138a of each heat sink 138 of the plurality of heat sinks 138 is coupled to the elongated hub element 139, each heat sink 138 of the plurality of heat sinks 138 may interconnect the elongated hub element 139 and the tubular wall 132 of the elongated support structure 122. Thus, each heat sink 138 of the plurality of heat sinks 138 may extend between the elongated hub element 139 and the tubular wall 132 of the elongated support structure 122. On the other hand, when the fin tip 138a of each heat sink 138 of the plurality of heat sinks 138 is spaced apart from the elongated hub element 139, each heat sink 138 of the plurality of heat sinks 138 may not be connected or coupled or in contact with the elongated hub element 139. Therefore, the fin tip 138 a of each of the plurality of fins 138 may be free.

[0077] According to various embodiments, as Figure 2A , Figure 2B , Figure 5A and Figure 5B In the example shown, when the plurality of fins 138 are radial fins, each fin 138 (in the form of radial fins) may extend radially between an elongated hub element 139 and an inner surface 132a of the tubular wall 132 of the elongated support structure 122. Thus, a fin tip 138a of each fin 138 may be coupled to the elongated hub element 139, and a fin base 138b of the fin 138 may be coupled to the inner surface of the tubular wall 132. Thus, each fin 138 of the plurality of fins 138 may interconnect the elongated hub element 139 and the tubular wall 132 of the elongated support structure 122. According to various embodiments, the elongated hub element 139 may serve as a hub from which the plurality of fins 138 (in the form of radial fins) may extend radially outward.

[0078] According to various embodiments, the elongated hub element 139 of the elongated support structure 122 may have any suitable elongated shape. According to various embodiments, the elongated hub element 139 of the elongated support structure 122 may include a cylindrical rod or a cylindrical tube.

[0080] According to various embodiments, the hollow lamp housing 140 may include a crown portion 148. The crown portion 148 may be a top portion or a top portion or a cap portion of the hollow lamp housing 140. Thus, the crown portion 148 of the hollow lamp housing 140 may extend across the top of the hollow lamp housing 140. According to various embodiments, the crown portion 148 of the hollow lamp housing 140 may abut the distal end 122b of the elongated support structure 122 of the light emitting module 110. Thus, the hollow lamp housing 140 may be assembled over the light emitting module 110 such that the underside of the crown portion 148 of the hollow lamp housing 140 may abut the distal end 122b of the elongated support structure 122 of the light emitting module 110.

[0081] According to various embodiments, the crown portion 148 of the hollow lamp housing 140 can be coupled to the distal end 122b of the elongated support structure 122 of the lighting module 110. According to various embodiments, the crown portion 148 of the hollow lamp housing 140 can be coupled to the distal end 122b of the elongated support structure 122 via a fastening element, including but not limited to a screw fastener, a snap-fit ​​fastener, a rivet fastener, a snap / latch, a retaining pin / clip, an adhesive, a suction element, a magnetic element, or a friction fastener. Figure 3A and Figure 3B As shown, as an exemplary embodiment, according to various embodiments, the crown portion 148 of the hollow lamp housing 140 can be coupled to the distal end 122b of the elongated support structure 122 via a screw 160. According to various embodiments, the crown portion 148 of the hollow lamp housing 140 can include a through hole 149 through which the screw 160 can be inserted so as to be screwed into the end portion 139a of the elongated hub element 139 of the elongated support structure 122. Therefore, the elongated hub element 139 of the elongated support structure 122 can include a threaded hole into which the screw 160 can be screwed so as to couple the crown portion 148 of the hollow lamp housing 140 to the elongated support structure 122. The through hole 149 of the crown portion 148 of the hollow lamp housing 140 can be along the central axis 118 of the lighting module 110 so as to be aligned with the slender hub element 139 of the slender support structure 122 of the lighting module 110 for coupling the crown portion 148 of the hollow lamp housing 140 to the slender support structure 122.

[0082] According to various embodiments, the crown portion 148 of the hollow lamp housing 140 can be opposite to the base opening 142 of the hollow lamp housing 140. Therefore, the crown portion 148 and the base opening 142 can be on opposite sides of the hollow lamp housing 140. Therefore, the light module 110 can be inserted into the hollow lamp housing 140, wherein the distal end of the elongated support structure 122 of the light module 110 abuts the crown portion 148 of the hollow lamp housing 140 and the base substrate 112 of the light module 110 at the base opening 142 of the hollow lamp housing 140. Figure 3A and Figure 3B As shown, as an example embodiment, when the hollow lamp housing 140 is cylindrical, the crown portion 148 and the base opening 142 may be located at two opposite circular ends of the cylindrical hollow lamp housing 140 along the longitudinal axis of the cylindrical hollow lamp housing 140. Therefore, relative to the longitudinal axis of the cylindrical hollow lamp housing 140, the crown portion 148 may be located at the top end of the cylindrical hollow lamp housing 140, and the base opening 142 may be located at the bottom end of the cylindrical hollow lamp housing 140.

[0083] According to various embodiments, the crown portion 148 of the hollow lamp housing 140 can include at least one ventilation hole 147. According to various embodiments, when the hollow lamp housing 140 is assembled to the light emitting module 110, the at least one ventilation hole 147 can be in fluid communication with the hollow passage 134 of the elongated support structure 122. Therefore, the at least one ventilation hole 147 can disperse heated air from the hollow passage 134 generated by heating of at least one row of red-green-blue light emitting elements 126 along the elongated support structure 122 of the light emitting module 110. Therefore, the at least one ventilation hole 147 can enable the heated air to be discharged from the elongated support structure 122 of the light emitting module 110 to the outside of the hollow lamp housing 140. Figure 3A and Figure 3B As shown, as an example embodiment, when the hollow channel 134 of the elongated support structure 122 of the light emitting module 110 is divided by a plurality of heat sinks 138 (or a plurality of radial heat sinks), the crown portion 148 of the hollow lampshade 140 may include at least one ventilation hole 147 for each sector of the divided hollow channel 134. Therefore, at least one ventilation hole 147 may be disposed at a position of the crown portion 148 of the hollow lampshade 140 corresponding to one sector of the divided hollow channel 134. Therefore, when the hollow channel 134 is divided into eight sectors, the crown portion 148 of the hollow lampshade 140 may include eight ventilation holes 147, one ventilation hole 147 for each sector of the hollow channel 134. According to various embodiments, the ventilation holes 147 (e.g., Figure 3A and Figure 3B The eight ventilation holes in the embodiment of the present invention can be distributed around the fastening element (ie, the through hole 149 for the screw 160).

According to various embodiments, there may be at least one ventilation line 145 for each ventilation hole 147.

[0085] According to various embodiments, the lamp 100 may include a control unit 170. According to various embodiments, the control unit 170 may be attached or mounted to the outer surface 148a of the crown portion 148 of the hollow lamp housing 140. Thus, the control unit 170 may be located at the top of the crown portion 148 of the hollow lamp housing 140. According to various embodiments, in the case where the control unit 170 is attached or mounted to the outer surface 148a of the crown portion 148, at least one ventilation line 145 at the outer surface 148a of the crown portion 148 may extend below the control unit 170 to an area of ​​the outer surface 148a of the crown portion 148 of the lamp housing 140 outside the control unit 170. Thus, in the case where the control unit 170 covers the at least one ventilation hole 147 at the outer surface 148a of the crown portion 148, the at least one ventilation line 145 at the outer surface 148a of the crown portion 148 may direct the exhausted air outside the coverage area of ​​the control unit 170 so as to disperse it to the external environment. Thus, at least one ventilation line 145 may be used to direct airflow from at least one ventilation hole 147 along the bottom of the control unit 170 to the outside of the control unit 170. According to various embodiments, at least one exhaust line 145 may include, but is not limited to, a channel, a duct, a pipe, a groove, a duct, or a slot.

Thus, the elongated support structure 122 of the light emitting module 110 may have a uniform diameter or width along its entire length.

[0105] According to example embodiments, according to various embodiments, the base substrate 112 of the light emitting module 110 may be a circuit board or a printed circuit board. In addition, a plurality of white light emitting elements 116 may be mounted on the circuit board or the printed circuit board.

Figure 5B FIG. 4 shows a top view of an elongated support structure 122 of a lighting module 110 according to various embodiments, wherein at least one row of red-green-blue light emitting elements 126 is separated from the elongated support structure 122. Figure 5A and Figure 5BAs shown, as an exemplary embodiment, according to various embodiments, the elongated support structure 122 of the light emitting module 110 may have a circular or octagonal cross-section. According to various embodiments, the light emitting module 110 may include eight rows of red-green-blue light emitting elements 126.

According to various embodiments, the elongated support structure 122 of the light emitting module 110 may have eight heat sinks 138 (e.g., eight radial heat sinks) within the hollow channel 134 of the elongated support structure 122. According to various embodiments, each heat sink 138 may be aligned with each row of red-green-blue light emitting elements 126. Therefore, each heat sink 138 may extend from a portion of the inner surface 132a of the elongated support structure 122, which corresponds to the portion to which the corresponding row of red-green-blue light emitting elements 126 of the elongated support structure 122 is attached.

Figure 6B 1 shows an example of how the lighting module 110 can illuminate the lamp 100 to display multiple horizontal distribution areas 104 of colors according to various embodiments. According to various embodiments, each row of red-green-blue light emitting elements 126 can illuminate a corresponding vertical area 102 of the hollow lamp housing 140 of the lamp 100. Therefore, depending on the number of rows of red-green-blue light emitting elements 126 disposed on the elongated support structure 122 of the lighting module 100, the hollow lamp housing 140 of the lamp 100 can be illuminated to display a corresponding number of vertical areas 102. For example, when the lighting module 100 has a plurality of vertical distribution areas 104, the vertical distribution areas 104 of the lamp 100 can be displayed. Figure 5A When eight rows of red-green-blue light emitting elements 126 are shown, the hollow lampshade 140 of the lamp 100 can be illuminated to display eight vertical regions 102 of different colors. According to various embodiments, each red-green-blue light emitting element 126 in each row of red-green-blue light emitting elements 126 can illuminate a corresponding horizontal region 104 of the hollow lampshade 140 of the lamp 100 within the same vertical region 102 associated with the row of red-green-blue light emitting elements 126. Therefore, the red-green-blue light emitting elements 126 at the same horizontal plane along all rows of red-green-blue light emitting elements 126 can illuminate a corresponding horizontal region 104 around the hollow lampshade 140 of the lamp 100. For example, when each row of red-green-blue light emitting elements 126 has eight vertical regions 102 of different colors, the hollow lampshade 140 of the lamp 100 can be illuminated to display eight vertical regions 102 of different colors. According to various embodiments, each red-green-blue light emitting element 126 in each row of red-green-blue light emitting elements 126 can illuminate a corresponding horizontal region 104 of the hollow lampshade 140 of the lamp 100 within the same vertical region 102 associated with the row of red-green-blue light emitting elements 126. Figure 2A and Figure 2B With the ten red-green-blue light emitting elements shown, the hollow lamp housing 140 of the lamp 100 can be illuminated to display ten horizontal regions 102 of different colors.

[0108] According to various embodiments, using the arrangement of a hollow lamp housing 140 surrounding an elongated support structure of a lighting module, the elongated support structure being lined with at least one row of red-green-blue light emitting elements 126, the lamp 100 can be controlled for vertical and / or horizontal red-green-blue zoned (segmented) lighting along the longitudinal direction (or height) of the hollow lamp housing 140. Thus, this configuration can open up more options for visual lighting patterns, spectrums, animations, rhythms (including circadian rhythms), and / or effects for the user.

[0109] Various embodiments have provided a lamp that can more efficiently and universally display more options of visual lighting patterns, light spectrums, animations, rhythms (including circadian rhythms), and / or effects to accommodate a user's expanded use of the lamp. In particular, various embodiments have the advantage of fully utilizing the height and circumference of the lampshade to display different areas of the lampshade that can be individually controllable to display different colors of lighting. Thus, partitioning the lampshade into different display areas provides a unique way for a user to be able to display more options of pictures, rhythms (including circadian rhythms), and / or effects.
