Description

FIELD

The present invention is related to a lighting apparatus, and more particularly related to a lighting apparatus with flexible component management.

BACKGROUND

LED modules have revolutionized lighting design, especially in industrial and commercial environments, where energy efficiency, flexibility, and cost-effectiveness are crucial. LED technology, known for its long lifespan and low energy consumption, has quickly become the preferred choice in these sectors. LED modules are self-contained units, combining LEDs with their circuitry, often in a compact and easy-to-install format. This modular design not only simplifies installation but also allows for easy replacement, an essential feature in settings where downtime can be costly. Their efficient energy usage results in lower utility costs, meeting sustainability goals while delivering substantial operational savings.

One of the main advantages of LED modules is their flexibility, making them suitable for a variety of applications and configurations. LED modules come in various shapes, sizes, and brightness levels, enabling designers to use them in everything from small accent lights to large-scale illumination systems. For instance, retail spaces often require different lighting intensities and hues for distinct sections. Here, LED modules can be used to highlight displays with vibrant colors or create subtle ambiance lighting, all while being energy-efficient and aesthetically pleasing. The adaptability of LED modules allows designers to achieve the desired lighting effects without compromising on performance or sustainability.

Durability is another crucial factor that makes LED modules popular in industrial and commercial applications. These modules are designed to withstand harsh environments, including exposure to dust, moisture, and extreme temperatures. This resilience makes them ideal for industrial spaces like warehouses and manufacturing facilities, where traditional lighting may be susceptible to frequent wear and tear. The durability of LED modules not only ensures consistent performance over time but also reduces maintenance costs, as they require less frequent replacements compared to other lighting technologies.

The industrial and commercial sectors demand lighting that can be easily configured and adapted to changing requirements, and LED modules meet this need well. Many LED modules offer customizable settings, such as adjustable brightness and color temperature, which can be controlled manually or via automated systems. This adaptability is especially beneficial in environments where lighting needs may vary throughout the day or in different work zones. For instance, in a manufacturing plant, bright lighting may be essential in the assembly area, while a softer, more focused light might be preferred in administrative zones.

LED modules are used in various lighting devices, each tailored to different design needs. For example, downlights, panel lights, and floodlights are commonly used in commercial spaces. Downlights provide focused illumination, suitable for office areas and meeting rooms, while panel lights offer broad, uniform lighting ideal for workspaces that require high visibility. Floodlights, on the other hand, are frequently used in outdoor or large indoor areas like warehouses and sports facilities, delivering powerful illumination over a wide area. Each of these devices utilizes LED modules, which enhance their energy efficiency and flexibility.

The environmental benefits of LED modules also play a significant role in their widespread adoption. LED lighting technology consumes less electricity than conventional lighting, helping reduce greenhouse gas emissions. Moreover, LED modules are often recyclable and contain no harmful materials like mercury, which is commonly found in fluorescent lighting. Many companies choose LED modules as part of their efforts to meet environmental regulations and reduce their carbon footprint, aligning with global sustainability goals.

Cost reduction is a critical consideration in the commercial and industrial sectors, where lighting expenses can constitute a large portion of operational costs. Although LED modules may have a higher initial cost compared to traditional lighting options, their long-term savings make them a cost-effective choice. Their low energy consumption translates to lower electricity bills, while their durability reduces replacement costs. Additionally, the modularity of LED lighting systems allows for incremental upgrades, which means that companies can invest in improvements over time without needing to overhaul entire lighting systems.

Another appealing feature of LED modules is their ease of installation and replacement. Modular design allows for simple setup and swift replacements, making LED lighting systems easier to maintain than traditional lighting. This is especially advantageous in large facilities, where the time and labor required for lighting maintenance can be substantial. For instance, in a warehouse setting, replacing a damaged lighting fixture can be time-consuming and disruptive. With LED modules, however, faulty components can be swapped out without needing to dismantle the entire fixture.

Furthermore, LED modules support sophisticated lighting control systems, enabling features like dimming, color-changing, and even smart lighting that adjusts based on occupancy or daylight availability. This level of control is particularly useful in commercial spaces such as hotels, where lighting needs vary widely across different areas. A conference room, for example, may need bright lighting for meetings but softer lighting for presentations or evening events. With LED modules, facilities can easily adapt to these different requirements, enhancing both functionality and energy efficiency.

LED modules are a preferred lighting solution in industrial and commercial settings due to their energy efficiency, durability, flexibility, and ease of use. They offer a versatile, environmentally friendly, and cost-effective alternative to traditional lighting, with modularity allowing for easy configuration and upgrades. These benefits, combined with the potential for substantial cost savings and a reduced carbon footprint, make LED modules a valuable asset in modern lighting design, supporting companies' operational and sustainability goals.

DETAILED DESCRIPTION

In FIG. 5, a lighting apparatus includes a driver housing 601, a first LED module 606, a first lens plate 605, a second LED module 651, a second lens plate 652, a first light wing 602, a second light wing 603, a first lens cover 611 and a second lens cover 610.

The first LED module 606 emits a first light 607. The second LED module 652 emits a second light 653.

The first light wing 602 has a first light opening and a first lens entrance 608. The first light 611 passes through the first lens plate 605 to escape from the first light opening.

Please also refer to FIG. 8, which shows a bottom view. In FIG. 8, the bottom size of the first light wing 602 has a first light opening 672. The second wing 603 may have the structure and thus is not illustrated for brevity.

The first light wing 602 and the second wing 603 are disposed on two sides of the driver housing 601.

The second light wing 603 has a second light opening and a second lens entrance 609. The second light passes 653 through the second lens plate 652 to escape from the second light opening.

The first lens cover 611 is used for concealing the first lens entrance 608. The second lens cover 610 is used for concealing the second lens entrance 609.

In FIG. 5, the first lens cover 611 is operated to expose the lens entrance 608 to insert the first lens plate 605. The second lens cover 610 conceals the second lens entrance 609.

In some embodiments, the first lens cover is operable to expose the first lens entrance for removing the first lens plate.

In some embodiments, the first lens entrance 608 is located at a first lateral wall 657 of the first light wing 602.

The first lens cover 611 is attached to the first lateral wall 657 with a first connector 612.

When the first lens cover 611 is operated to expose the first lens entrance 608, the first connector 612 is still attached to the first lateral wall 657.

This design offers several key advantages, particularly in making lens replacement or maintenance more user-friendly. By attaching the first lens cover to the lateral wall with a secure connector, the lens cover remains fixed in place even when opened. This design prevents the cover from being fully detached and eliminates the need for the user to hold or set the cover aside during lens replacement. For users performing maintenance at elevated or challenging locations, such as high walls or overhead fixtures, this feature reduces the risk of dropping the cover, enhancing safety and convenience.

Another benefit of this configuration is the ease and efficiency it brings to maintenance tasks. Since the lens cover does not need to be manually held or temporarily stored, users can focus fully on accessing and replacing the lens plate without interruption. This design minimizes the number of steps required to open, hold, and reattach the cover, making the process smoother and more streamlined. In settings where frequent lens changes or maintenance are necessary, this design can significantly reduce time and effort, contributing to better productivity and overall ease of use.

Additionally, the design's secure attachment mechanism provides greater durability and reliability. The fixed connection of the cover to the lateral wall reduces wear and tear on the components since they do not require repeated removal and reattachment. This robust setup is particularly beneficial in industrial or commercial environments, where equipment is often subject to regular use and potential handling stresses. By keeping the lens cover connected, the design supports long-term stability and ensures that each component remains properly aligned, reducing maintenance costs and enhancing the lifespan of the system.

In some embodiments, the first lens cover further has a first attaching unit 613.

The first attaching unit 613 and the first connector 612 are disposed on two sides of the first lens cover 611.

The first attaching unit 613 and the first connector 612 together attach the first lens cover 611 to conceal the first lens entrance 608.

In some embodiments, the first attaching unit 613 is a screw.

In some embodiments, the first attaching unit is an elastic block to squeeze into a lock hole aside the first lens entrance.

FIG. 10 shows such an example, the first attaching unit 701 is a rubber block has a reverse hook 702 at its front end. Users presses the first attaching unit 701 into the lock hole 703 of the lateral wall of the first wing aside the first lens entrance.

This design significantly simplifies the process of securing the lens cover by using an elastic rubber block with a reverse hook at the front. When the user presses the elastic block into the lock hole near the lens entrance, the block compresses, easily sliding into place without requiring additional fasteners or tools. The elasticity of the rubber material allows it to adapt to the dimensions of the lock hole, creating a snug fit that enhances stability while maintaining ease of installation. This approach not only speeds up the assembly process but also minimizes the effort needed from the user, as the block naturally aligns and settles into position.

The inclusion of a reverse hook on the rubber block adds a reliable locking mechanism that keeps the lens cover securely in place. Once inserted, the reverse hook prevents the lens cover from shifting or becoming detached without intentional removal, ensuring that the lens entrance remains concealed and protected. This secure locking feature also eliminates the need for complex locking systems, as the cover remains attached until an external force is applied to remove it. This design choice improves durability and prevents accidental exposure of the lens entrance, making it a practical solution for both quick access and dependable sealing.

In some embodiments, the first lens cover is made of elastic plastic material, and the first lens cover is squeezed to fit to the first lens entrance to conceal the first lens entrance.

In some embodiments, the first lens plate is a first light guide plate.

FIG. 7 shows such an example. Instead of placing the lens plate below the LED module. In the example of FIG. 7, the LED module 721 emits a light from a lateral side of the light guide plate 722, the light is reflected and refracted via the light output surface.

The first LED module emits the first light into a first lateral surface of the first light guide plate.

The first lateral surface is perpendicular to the first light opening.

In some embodiments, the first lens plate has multiple convex-concave lens structure 723 for diffusing the first light, as illustrated in FIG. 7.

The inclusion of multiple convex-concave lens structures on the first lens plate enhances the diffusion of the output light, resulting in a more even and uniform light distribution. Each convex-concave lens structure acts as a small diffuser, scattering light as it passes through. This scattering effect reduces harsh spots and spreads light across a wider area, creating a softer and more homogeneous illumination. By diffusing the light at multiple points on the lens plate, the design ensures that any concentrated light sources or bright spots are evenly dispersed, which improves the overall quality and consistency of the output.

Furthermore, the multiple convex-concave structures work together to provide a greater degree of light manipulation, enabling precise control over the distribution pattern. This is especially beneficial in settings where uniform lighting is essential, such as in industrial or commercial environments, where even illumination can reduce eye strain and enhance visibility. By ensuring that light is evenly spread, the design reduces glare and unwanted shadows, creating a more comfortable and effective lighting experience.

In some embodiments, the first light wing has a first sliding track for sliding the first lens plate into the first light wing.

In some embodiments, the first siding track has multiple sub-tracks for placing the first lens cover with different distances to the first LED module.

FIG. 6 shows there are three sub-tracks 751, 752, 753 that provide three different distance from the LED module 754 to provide different light output pattern, e.g. light beam spreading angles.

In FIG. 5, a first manual switch 681 is disposed aside the first lens entrance 608 for users to set a light setting of the first LED module.

The first manual switch 681 is concealed by the first lens cover 611.

The first manual switch 681 is exposed when the first lens cover 611 is partly detached from the first lens entrance 608.

In some embodiments, the first LED module 802 and the first lens plate 803 are integrated as a replaceable module to be replaced from the first lens entrance.

In FIG. 11, the lens cover has electrode 805 for routing a driving current, e.g. driving current 604 in FIG. 5, from a driver in the driver housing to the first LED module.

In FIG. 11, the first LED module has a power socket 804.

The first lens cover 801 has a power pin as the electrode 805 to insert into the power socket 804 of the first LED module.

In some embodiments, the first lens cover is attached to the first light wing using a connection of the power socket and the power pin as illustrated in FIG. 11

In FIG. 5, the driver housing has an installation groove 685 for inserting the first light wing 602.

In some embodiments, the first light wing is rotatable with respect to the driver housing to change a direction of the first light. FIG. 5 shows that the second light wing 603 is rotated with respect to the driver housing 601.

In some embodiments, a rotation shaft 626 is used for fixing the first light wing to the driver housing.

Please also refer to FIGS. 1 and 2, where FIG. 2 shows an assembly diagram of a light fixture with a quick lens replacement feature, according to an embodiment of this application.

In a specific embodiment, the lens 104 is fully inserted into the slot track of the lamp body 102. The end cap 105 is rotated to align with the side cover 103, and is secured to the side cover 103 with screws, fully sealing the lens 104 inside the lamp body 102.

In some embodiments, a detachable fit is used between the end cap 105 and the side cover 103. The entire fixture does not need to be disassembled; by simply removing the end cap 105, the lens 104 can be taken out from the slot track of the lamp body 102 and replaced with a lens 104 of a different light-guiding structure, allowing for versatile lighting configurations.

FIG. 3 illustrates a schematic diagram of the end cap area structure of a light fixture with a quick lens replacement feature, according to an embodiment of this application.

In certain embodiments, one end of the end cap 105 engages with the side cover 103 in an embedded fit. Once assembled, the end cap 105 can rotate freely relative to the side cover 103. This structure enables the end cap 105 to rotate to a position aligned with the side cover 103's aperture.

FIG. 4 shows another schematic diagram of the end cap area structure of a light fixture with a quick lens replacement feature, according to an embodiment of this application.

In specific embodiments, one end of the end cap 105 engages with the side cover 103 via screws. Loosening the screws releases the end cap 105, allowing it to rotate, after which the lens 104 inside the slot track of the lamp body 102 can be replaced.

In another embodiment, the end cap 105 has a screw hole at one end, with a blank area in the middle section of the screw hole. Loosening the screw enough for the threaded part to enter this blank area allows the end cap 105 to rotate, facilitating the replacement of the lens 104 without fully removing the screw, thereby preventing the loss of screws.

This application proposes a light fixture with a quick lens replacement feature, achieved by adding a front-to-back through slot track at the lower part of the lamp body and a small window on the side cover, along with a detachable end cap. This design allows for the quick replacement of lenses with different beam angles without needing to disassemble the entire fixture. The blank area in the middle of the screw hole on one end of the end cap, combined with the embedded design at the other end, enables end cap rotation and lens replacement without fully removing the screws. This feature reduces the risk of losing components during disassembly and improves installation and maintenance convenience, meeting user requirements for different lighting configurations in various scenarios.

In summary, the side end cap structure proposed in this design offers practical advantages in terms of consistent appearance, ease of use, and enhanced user experience.
