Abstract
Description
iDESCRIPTIONTitle of Invention: A Rotatable Cover Lamp for Observing Sabbath and Religious HolidaysName of Inventor: Meyer R CohenInvention Type: ElectricalBackground:
[0001] Observant Orthodox Jews face a unique challenge during the Sabbath and Jewish holidays: the prohibition against using electrical switches. This restriction extends to the operation of lamps, which traditionally require an on / off switch to control light.
[0002] Current solutions include various Shabbos lamps that incorporate mechanical covers to block or reveal light without switching the lamp on or off electrically. However, these existing solutions have limitations that the present invention, the present invention seeks to address.Invention Summary:
[0003] The present invention relates to a lamp apparatus, referred to herein as the "The Rotatable Cover Lamp," designed to enable light control without the use of an electrical switch. The lamp is equipped with a rotatable external cover that selectively obstructs or permits light emission by aligning a window with the light source, thus providing a compliant solution for Sabbath observance.Brief Description of the Drawings:

[0005] Figure 2: A frontal view showing how the rotatable cover of the invention is inserted into the base.
[0006] Figure 3: A top view of the rotatable cover of the present invention.
[0007] Figure 4: A front view of the rotatable cover.
[0008] Figure 5: A perspective view of the rotatable cover.Invention DescriptionTechnical Field:
[0009] The invention pertains to the field of electrical lighting devices, specifically to lamps designed for use by individuals observing religious practices that restrict the use of electrical switches during certain periods.Technical Terms:
[0010] 1 . Lamp Base: The structural component housing the light source.
[0011] 2. Rotatable Cover: A cylindrical or conical component that encases the lamp base and can be rotated around its axis.
[0012] 3. Window: An aperture in the rotatable cover that allows light to pass through when aligned with the light source.
[0013] 4. Sconce Lighting: A lighting method that directs light upwards or to the sides, reducing direct glare to the eyes.Detailed Description of the Invention:
[0014] The Rotatable Cover Lamp consists of a lamp base (70) containing the light source (30), a rotatable cover (20) having a cap on top (10), encasing the lamp base (70), and a window integrated into the cover.
[0015] The lamp base (70) is configured to support and house the light source (30), typically an LED or incandescent bulb.
[0016] The rotatable cover (20) is designed to fit snugly around the lamp base (70) and is capable of 360-degree rotation.Operational Mechanism:
[0017] The rotatable cover (20) includes a window which, when aligned with the light source, permits light to emit from the lamp. When the cover is rotated such that the window is misaligned with the light source, the light is blocked.
[0018] This design allows the user to control light emission without engaging an electrical switch, thereby complying with Sabbath restrictions.Aesthetic and Functional Design:
[0019] The Rotatable Cover Lamp features a sleek, minimalistic design that enhances any interior decor.
[0020] The lamp's external cover mechanism avoids the halachic concerns associated with internal sliding covers found in some existing Shabbos lamps.Benefits Over Existing Technology:
[0021] The external rotatable cover is fully exposed, mitigating any halachic issues associated with internal cover mechanisms.
[0022] The compact and lightweight design makes the The Rotatable Cover Lamp portable and suitable for various room settings.
[0023] The use of sconce lighting directs light away from the user's direct line of sight, reducing eye strain and providing a more comfortable lighting experience.
[0024] The Rotatable Cover Lamp's lightweight construction facilitates easy handling and transport, making it ideal for users of all ages.Improvements on Pre-Existing Inventions:
[0025] The Rotatable Cover Lamp addresses several deficiencies found in current Shabbos lamps on the market:External Cover Mechanism:
[0026] Unlike existing lamps with internal sliding covers, the The Rotatable Cover Lamp’s external cover is fully exposed, providing a solution that adheres to stricter halachic standards.Size and Portability:
[0027] The compact and minimalistic design of the Rotatable Cover Lamp ensures it is aesthetically pleasing and practical for various room settings. Its lightweight nature makes it easy to transport.Light Direction:
[0028] Traditional Shabbos lamps often direct light towards the user, causing discomfort. The Rotatable Cover Lamp’s sconce lighting directs light upwards or sideways, offering a gentler and more comfortable illumination reflecting off the wall. The rotatable cover of the lamp is designed for ease of use and can easily be twisted with as little as two fingers, allowing users to adjust the light without effort.Ease of Use:
[0029] Heavier lamps can be challenging for older adults and children to handle. The Rotatable Cover Lamp’s lightweight construction and ease of disassembly make it user-friendly and ideal for travel.Conclusion:
[0030] The Rotatable Cover Lamp provides a significant advancement over existing Shabbos lamps by offering a design that is both religiously compliant and user-friendly. Its external rotating cover mechanism, sleek design, indirect lighting, and lightweight construction and disassemble feature make it a versatile and practical solution for Sabbath observant Jews. This invention not only meets the functional requirements of Sabbath observance but also enhances the user experience with its thoughtful design and ease of use.
