Definitions

• lamps such as lightbulbs.
• smart lamps that are able to communicate with other devices, e.g., to provide wireless connectivity for wireless control of the lamp.
• One essential structural element for enabling wireless communication is an antenna.
• the lamp may further comprise an exhaust tube 350 for transporting gas to or from the bulb envelope.
• the exhaust tube may, for instance, be used to fill the bulb envelope with an inert gas (and exhaust air) during manufacture.
• the exhaust tube may then be capped or otherwise closed (e.g., melted with a flame) to prevent/avoid the loss of inert gas from the bulb envelope.
• Suitable example materials and construction techniques for forming an exhaust tube are well known in the art.
• Figure 3 also demonstrates how the pinch portion may be formed from a monolithic piece of material, e.g., such that it contains no or minimal gas/air outside of any present in any components secured in/to the pinch portion such as the exhaust tube 350. This is in comparison to other portions of the stem which may be hollow.
• Figures 4 and 5 provide specific views of the antenna 310 for improved understanding.
• Figure 4 provides a side view of the antenna 310, more clearly demonstrating how the antenna is formed from a winding portion 311 and an elongate portion 312.
• Figure 5 provides a top-down view of the antenna 310, which demonstrates how the winding portion 311 may have a helical structure.
• Figure 6 illustrates a technique for manufacturing the antenna-stem assembly 300 according to an embodiment.
• an antenna 310 is provided.
• a portion of the antenna (which, for this example, may be initially elongate) is wrapped around the support 115 to form the winding portion 311.
• the support 115 may be threaded through a winding portion 311 that has been pre-made (e.g., pre-wound) before production of the assembly 300 begins.
• the remainder of the antenna is positioned through the tube-shaped portion 615 of the stem. In this way, the antenna 310 is formed to have a winding portion 311 and an elongate portion 312.
• a second process 660 the stem is pinched to secure the support 115 and the antenna 310.
• Process 660 can be performed by, for instance, heating the stem at a desired location until the material becomes viscous and/or starts to flow. The stem may then be squeezed, pinched or otherwise manipulated to bring two opposing sides of the stem 120 together at the desired location. This pinching creates the pinch portion 123 at the desired location.
• the desired location may be a location at which the support and antenna are present. The pinch portion thereby secures the stem to the support 115 and the antenna 310. Heating and pinching the stem in the second process 660 thereby creates the first chamber 121, the second chamber 122 and the pinch portion 123 of the stem 120 previously described.
• an antenna-stem assembly 300 comprising a stem 120 and an antenna 310 partially housed in the stem.
• a winding portion 311 of the antenna 310 is located within a first chamber 121 of the stem.
