Therefore, the present disclosure envisages a multifunctional automotive cabin lamp (hereinafter referred to as system (100). The present disclosure is explained with reference to the figure 1- figure 6.
Figure 1 illustrates the isometric view of a multifunctional adjustable cabin lamp for an automotive vehicle, in accordance with an embodiment of the present disclosure. Figure 1 describes the top of the assembly, the ceiling of vehicle (135) is illustrated, where the lamp assembly is mounted. Beneath the ceiling, the reflector (105) is positioned. The reflector (105) directs light efficiently from the light source (125), enhancing illumination within the vehicle cabin. The lamp assembly is connected to the ceiling by a joint mechanism (120), which provides adjustability, allowing users to position the light according to their needs. This joint mechanism is repeated at various points in the assembly to offer versatile movement and stability. The fixed arms (130) are shown connecting the components, ensuring structural integrity and supporting the reflector and other parts of the lamp assembly. Below the fixed arms, the projector lens (110) is depicted, which focuses the light into a specific light beam (126) to target illumination in desired areas. The light source (125a, 125b), located within the assembly, acts as the primary light source. The entire setup is designed to offer customizable lighting in the vehicle cabin, with components like the reflector (105) and projector lens (110) working in tandem to optimize light distribution and focus.
Figure 2 illustrates an operative view of the adjustable cabin lamp of Figure 1. Figure 2 provides an understanding of the arrangement where the top of the assembly, the Reflector (105) is mounted. The reflector is responsible for directing the light emitted from the light source (125a, 125b) below it, ensuring efficient illumination within the vehicle cabin. The reflector (105) is supported by a joint mechanism (120) that allows for the adjustable positioning of the lamp. This joint mechanism provides the necessary flexibility for angling the light according to user preferences. Beneath the joint mechanism (120) and reflector (105), the Fixed Arms (130) are depicted. These arms (130) provide structural support to the lamp assembly, connecting the reflector (105) and other components securely. At the bottom of the assembly, a projector lens (110) is shown, which focuses the light emitted from the light source (125a, 125b) into a defined light beam (126). This allows for targeted illumination of specific areas within the cabin. The assembly is designed to be mounted onto the ceiling of a vehicle (135), where the joint mechanisms (120) ensure that the lamp can be adjusted and locked into the desired position. The light source (125a, 125b), positioned within the assembly, provides the light source, with the reflector (105) and projector lens (110) working together to optimize the light output.
In an embodiment, concept 1 of the present disclosure introduces snap-grid locking the which is situated at the top of the assembly, the reflector (105) is visible, which helps in distributing light throughout the cabin. The lamp assembly is structured around a joint mechanism (120) that enables rotational adjustment, providing flexibility in directing light as needed. The fixed arms (130) connect various components of the lamp, offering support and maintaining the integrity of the assembly. Below the joint mechanism is the projector lens (110), which focuses light in a specific area for targeted illumination as shown in Figure 3A-3C.
In an embodiment, concept 2 of the present disclosure introduces the use of memory foam sheets (140) within the joint mechanism (120) of the adjustable cabin lamp (100). This configuration leverages the memory foam's unique properties to enhance the lamp's rotational freedom while providing a tight interference that locks the lamp securely in place once positioned. The memory foam (140) is strategically placed along the inner circumference of the joint mechanism, allowing the lamp to rotate or tilt smoothly in any direction. Once the desired orientation is achieved, the memory foam compresses to stabilize the lamp, preventing unintended movement due to vibrations. The projector lens (110) at the bottom focuses light precisely, with the memory foam ensuring that the lamp remains in the set position, combining flexibility and stability for versatile lighting within the vehicle cabin as shown in Figures 4A and 4B.
In an embodiment, concept 3 of the present disclosure illustrates the motorized rotation feature of the adjustable cabin lamp (100), as shown in Figures 5A and 5B. This concept integrates a motor within the joint mechanism (120), enabling automated rotation of the lamp for precise control over the light direction. In Figure 5a, the side view highlights the spherical housing equipped with a locking mechanism (150) that works in tandem with the motorized system to ensure the lamp remains securely positioned after rotation. The motorized rotation allows for smooth and controlled light source movement, with the housing rotating around the cylindrical base. Figure 5B provides a bottom-up perspective, showing the housing's rotation in response to the motor's activation, with arrows indicating the rotational directions. The hook-like structures are visible on the housing aiding in the locking process, securing the lamp in place once the desired orientation is reached. This motorized system enhances the lamp's adjustability, allowing for effortless changes in light direction to suit varying needs within the vehicle cabin.
Figure 6 illustrates a flowchart that includes the steps involved in a method (200) for configuring a cabin lamp for a vehicle, in accordance with an embodiment of the present disclosure. The order in which method (200) is described is not intended to be construed as a limitation, and any number of the described method (200) steps may be combined in any order to implement method (200), or an alternative method (200). Furthermore, method (200) may be implemented by processing resource or electronic device(s) through any suitable hardware, non-transitory machine-readable medium/instructions, or a combination thereof. The method (200) comprises the following steps:
At step (202), the method (200), includes mounting the cabin lamp (100) on the ceiling (135) of the vehicle by attaching a first joint mechanism (120a) to the ceiling (135).
At step (204), the method (200), includes attaching a reflector (105) to the first joint mechanism (120a) beneath the ceiling (135) to enable rotational adjustment of the reflector (105) for optimal light distribution across a wide area of the vehicle’s interior.
At step (206), the method (200), includes integrating an uplighter light source (125a) within the structure of the reflector (105) to emit light for illuminating the cabin.
At step (208), the method (200), includes supporting the reflector (105) using at least a pair of fixed arms (130), which connect the reflector (105) to a second joint mechanism (120b) located beneath the reflector (105).
At step (210), the method (200), includes attaching a downlighter light source (125b) to the second joint mechanism (120b), positioning the downlighter light source (125b) within the second joint mechanism (120b) to provide focused lighting.
At step (212), the method (200), includes attaching a projector lens (110) beneath the second joint mechanism (120b), configuring the projector lens (110) to focus the light emitted by the downlighter light source (125b) into a targeted light beam for precise illumination of specific areas within the vehicle.
At step (214), the method (200), includes adjusting the orientation of the projector lens (110) and the reflector (105) using the second joint mechanism (120b) and the first joint mechanism (120a), respectively, to provide a combination of spread and focused lighting within the vehicle cabin.
In an embodiment, the cabin lamp (100) is configured to provide wide-area illumination for general cabin lighting. The reflector (105) and the uplighter light source (125a) work in tandem to distribute light uniformly across the interior of the vehicle. This configuration is ideal for scenarios where overall visibility is required, such as during passenger entry, exit, or when cleaning the vehicle.
In another embodiment, the cabin lamp (100) can be adjusted to provide focused lighting. The second joint mechanism (120b) allows the projector lens (110) to be rotated and positioned to direct the light beam to specific areas within the vehicle, such as reading lights for individual passengers. The downlighter light source (125b) emits a precise light beam through the projector lens (110), ensuring minimal disturbance to other passengers.
In an alternative embodiment, the cabin lamp (100) is used to provide adjustable lighting based on user preferences. The rotational capability of both the first joint mechanism (120a) and the second joint mechanism (120b) allows passengers to customize the lighting angle, switching between a soft ambient glow or focused task lighting for activities like reading or using electronic devices.
In yet another embodiment, the cabin lamp (100) is equipped with an automatic adjustment feature. The lamp can integrate with the vehicle's control system to automatically adjust the lighting based on the time of day or the amount of ambient light within the cabin. During night-time driving, the focused light from the projector lens (110) can be directed toward individual passengers without disturbing the driver, ensuring safety and comfort.
In an embodiment, the cabin lamp (100) can be used for specific illumination requirements such as illuminating cargo areas or compartments. The focused light from the projector lens (110) can be adjusted to provide targeted lighting in storage spaces, ensuring visibility without consuming excessive energy or illuminating unnecessary areas of the cabin.
In operation, the cabin lamp (100) is mounted on the ceiling (135) of the vehicle and is configured to provide both wide-area illumination and focused lighting. The uplighter light source (125a) is integrated within the reflector (105), spreading light across the cabin through the rotational adjustment enabled by the first joint mechanism (120a). For specific lighting needs, the second joint mechanism (120b) allows for the precise positioning of the projector lens (110), which focuses the light emitted by the downlighter light source (125b) into a targeted beam. This focused beam can be adjusted based on user requirements by rotating the projector lens (110) to illuminate specific areas of the vehicle, such as reading lights for individual passengers or illumination of cargo compartments. The combination of these components allows the lamp to provide flexible and adaptable lighting for various interior scenarios
Advantageously, the cabin lamp (100) offers a highly flexible lighting solution for vehicles by combining both broad-area and focused illumination in a single system. The rotational adjustability of both the reflector (105) and the projector lens (110) allows passengers to customize the lighting according to their needs, improving passenger comfort and convenience. The dual light source setup—one for wide-area lighting and the other for targeted illumination—ensures energy efficiency while providing adequate lighting where it's most needed. Moreover, the use of two joint mechanisms (120a, 120b) offers enhanced control over the lighting direction, minimizing glare and optimizing visibility within the vehicle. This versatile configuration enhances safety, user experience, and operational efficiency, making it a superior lighting solution compared to conventional fixed cabin lamps.
