Description

Technical Field

[0001] This invention relates to the field of hotel lighting technology, and more specifically, to an environmentally friendly lighting fixture with air purification function and a purification method. Background Technology

[0002] In modern hotel environments, guest room lighting typically functions primarily to meet basic lighting needs. Common table lamp designs are often limited to optimizing light source configuration and appearance, resulting in relatively simple functions. Most hotel table lamps only offer basic controls such as turning the light on and off and adjusting brightness, failing to integrate other practical functions. This leads to an increase in the number of electrical appliances in guest rooms, increasing not only procurement and maintenance costs but also occupying limited space.

[0003] Meanwhile, as consumers increasingly demand a healthier and higher-quality living environment, air quality has become a crucial factor affecting hotel comfort. To improve indoor air quality, many hotels have to install separate air purifiers. These devices are typically bulky and require dedicated placement, impacting the overall aesthetics of guest rooms and increasing operating costs. Furthermore, air purifiers operate independently without coordinated control with the lighting system, leading to energy waste and inconvenience. More significantly, some air purifiers are quite noisy, potentially disrupting guests' rest.

[0004] In the prior art, for example, Chinese patent CN220892087U discloses a multi-functional table lamp for hotels. The disclosed document describes a lamp head with three light color modes: warm light, cool light, and natural light. This design prevents the light source from being too concentrated, avoiding high brightness that could irritate the eyes and affect vision. However, this lamp lacks air purification functionality, failing to meet the air purification needs of hotels. Therefore, there is an urgent need for a multi-functional table lamp that integrates lighting and air purification, achieving both functions without increasing space occupancy. This would enhance the intelligence and comfort of guest rooms and reduce hotel equipment procurement and management costs. Summary of the Invention

[0005] The present invention aims to solve the technical problems mentioned in the background art above, and to provide an environmentally friendly lamp with air purification function and a purification method.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an environmentally friendly lamp with air purification function, comprising a lamp body, wherein the lamp body comprises a three-layer integrated structure from top to bottom, including: The upper air purification and main lighting assembly includes a first lampshade, a small fan device located at the bottom of the first lampshade, an air filter device located above the small fan device, a negative ion generator located on the clean air output side of the air filter device, and a first light source located inside the first lampshade. The first light source is an LED bulb with an E27 interface, serving as the main lighting source. The air filter device is supported by an acrylic sheet at the top of the inner wall of the first lampshade. The small fan device includes three low-noise DC brushless fans, arranged in a 120° ring around the axis of the first lampshade. The auxiliary lighting assembly in the middle layer includes a second lampshade and a second light source disposed therein. The top of the second lampshade is connected to the center of the bottom of the first lampshade, and the second light source is an LED light strip. The lower-level audio and support components include two small audio devices symmetrically arranged around the bottom periphery of the second lampshade, a metal support rod, a metal base, and an intelligent control module. The metal base is placed on the tabletop, and the metal support rod is vertically installed at the top of the metal base and connected to the second lampshade. The intelligent control module is integrated inside the metal support rod and includes a microprocessor unit, a Bluetooth communication unit, and a Wi-Fi communication unit. It is electrically connected to the first light source, the second light source, the small fan device, the negative ion generator, and the small audio devices, and is powered by an adjustable switching power supply.

[0007] Furthermore, the first lampshade is a milky white acrylic translucent lampshade, which serves as the main lampshade to provide centralized reading and basic lighting in the guest room; the first light source has a power of 5W, a color temperature of 3000K, and an adjustable brightness range of 100-400 lumens.

[0008] Furthermore, the inner diameter of the acrylic sheet is smaller than the top opening diameter of the first lampshade, and the air intake surface of the small turbine fan faces downward, which is used to draw ambient air into the interior of the first lampshade and upward through the air filter device.

[0009] Furthermore, the second lampshade is a milky white acrylic translucent lampshade, serving as an auxiliary lampshade. The second lampshade is smaller than the first lampshade, and the top of the second lampshade is connected to the center of the bottom of the first lampshade via a snap or threaded structure. The second light source has a power of 12W, a length of 1 meter, and a color temperature of 3000K. It is arranged around the inside of the second lampshade to provide a soft, ring-shaped halo for use as auxiliary ambient lighting.

[0010] Furthermore, the metal base has an embedded metal weight, and the bottom of the metal base is sealed with a tablecloth bottom cover made of non-slip silicone with an elastic edge. An adjustable power cord is connected to the right end of the metal base. The metal support rod is made of high-strength aluminum alloy and anodized. The two small speaker devices are symmetrically distributed and are flat stereo speakers. The intelligent control module supports remote control via APP, voice commands, and physical knob operation. It is used to receive local trigger signals or remote control commands from smart terminals or hotel management systems via Bluetooth / Wi-Fi.

[0011] Furthermore, the air filter device is a detachable cylindrical structure, comprising a primary filter, a HEPA high-efficiency filter, and an activated carbon filter layer arranged sequentially from bottom to top. The outer periphery of the air filter device forms a seal with the inner wall of the first lampshade, and the bottom of the air filter device is supported and fixed by the acrylic sheet. The primary filter is a washable metal mesh cover, and the HEPA high-efficiency filter and activated carbon filter layer are replaceable structures. The activated carbon filter layer uses columnar coconut shell activated carbon. The top of the air filter device has an integrally formed handle structure, and the side wall has a rotating buckle that cooperates with the groove on the inner wall of the first lampshade. The bottom of the air filter device has a sealing ring that is sealed to the acrylic sheet.

[0012] Furthermore, the negative ion generator is positioned adjacent to the clean air output side of the air filter device, and the negative ion concentration is [missing information]. The negative ion generator and the small fan device are linked to start and stop.

[0013] Furthermore, the acrylic sheet is a frosted annular structure with a thickness of 4mm and a light transmittance of ≥90%, and its outer diameter matches the inner wall of the first lampshade.

[0014] Furthermore, the intelligent control module incorporates a PM2.5 sensor, a TVOC sensor, and a temperature and humidity sensor to collect environmental data in real time and display the air quality level via RGB LED indicators or a mobile app.

[0015] A purification method using an environmentally friendly light fixture with air purification function, comprising the following steps: S1: Power is turned on via the adjustable switching power supply line, and the intelligent control module starts a self-test program to initialize the lighting, fan, audio and sensor modules; S2: The small fan device draws in indoor air from the bottom of the first lampshade, and first passes through the lower primary filter to intercept large particulate impurities; S3: Driven by the fan, the air drawn in passes through a detachable air filter device, which sequentially passes through a primary filter, a HEPA high-efficiency filter, and an activated carbon filter layer for triple filtration. Particulate pollutants such as dust, pollen, and PM2.5 in the air are effectively intercepted and adsorbed by the filter, while gaseous pollutants such as VOCs are adsorbed by the activated carbon. S4: Clean air passes through the negative ion generator area and is injected with a high concentration of negative ions, which further inactivates viruses and settles micro-dust. S5: Fresh air rich in negative ions is evenly discharged from the air outlet at the top of the lamp body, forming an airflow circulation from bottom to top, avoiding secondary dust; S6: The intelligent control module dynamically adjusts the fan speed, negative ion intensity, lighting brightness, and sound status based on sensor data; S7: When the filter element resistance increases or the usage time reaches the threshold, the system will remind the user to disassemble, clean or replace the air filter element device via APP or indicator light. S8: While providing main and auxiliary lighting, it continuously purifies the air and plays background music.

[0016] The beneficial effects of this invention are as follows: This invention provides an environmentally friendly lamp and purification method with air purification function, which integrates four functions—table lamp lighting, air purification, negative ion generation, and Bluetooth speaker—into one product. It directly replaces the traditional table lamp and separate air purifier in hotel rooms, avoiding the additional costs of purchasing, storing, and maintaining two separate devices, thus reducing operating costs and space occupation for hotels. It employs a triple filtration system of "primary filter + HEPA high-efficiency filter + activated carbon," combined with a negative ion generator, which not only effectively removes particulate pollutants such as PM2.5, pollen, and dust, but also adsorbs gaseous pollutants such as formaldehyde and VOCs, as well as odors. Simultaneously, it releases negative ions to settle fine dust and freshen the air, improving the health quality of the guest room environment. Both the main lighting (E27 bulb) and auxiliary lighting (LED light strip) use a 3000K warm color temperature, and a milky white acrylic lampshade creates soft, glare-free diffused light, fostering a warm and comfortable hotel atmosphere and protecting eyesight.

[0027] like Figures 1 to 5 As shown, an embodiment of the present invention provides an environmentally friendly lighting fixture with air purification function, including a lamp body, which comprises a three-layer integrated structure from top to bottom, including: The upper air purification and main lighting components include a first lampshade 6, a small fan device 8 located at the bottom of the first lampshade 6, an air filter device 9 located above the small fan device 8, a negative ion generator located on the clean air output side of the air filter device 9, and a first light source 7 located inside the first lampshade 6. The first light source 7 is an LED bulb with an E27 interface, which serves as the main lighting source. The air filter device 9 is supported by an acrylic sheet 10 at the top of the inner wall of the first lampshade 6. The small fan device 8 includes three low-noise DC brushless fans, which are arranged in a 120° ring around the axis of the first lampshade 6. The auxiliary lighting components in the middle layer include a second lampshade 3 and a second light source 5 disposed therein. The top of the second lampshade 3 is connected to the center of the bottom of the first lampshade 6, and the second light source 5 is an LED light strip. The lower-level audio and support components include two small speaker devices 4 symmetrically arranged around the bottom periphery of the second lampshade 3, a metal support main rod 2, a metal base 1, and an intelligent control module. The metal base 1 is placed on the tabletop, and the metal support main rod 2 is vertically set at the top of the metal base 1 and connected to the second lampshade 3. The intelligent control module is integrated inside the metal support main rod 2. The intelligent control module integrates a microprocessor unit, a Bluetooth communication unit, and a Wi-Fi communication unit, and is electrically connected to the first light source 7, the second light source 5, the small fan device 8, the negative ion generator, and the small speaker devices 4. It is powered by an adjustable switching power supply cable 11.

[0028] In one embodiment, the first lampshade 6 is a milky white acrylic translucent lampshade, serving as the main lampshade to provide centralized reading and basic lighting in the guest room; the first light source 7 has a power of 5W, a color temperature of 3000K, and an adjustable brightness range of 100-400 lumens; the first lampshade 6 is made of milky white acrylic material, which has high light transmittance and good diffuse reflection characteristics, and can transform the point light source emitted by the E27 LED bulb into a soft, uniform, and glare-free surface light source, effectively avoiding visual fatigue caused by direct light shining on the eyes, making it particularly suitable for use in hotel rooms for reading at night; the selection of a warm white light color temperature of 3000K simulates the natural spectrum of dusk or candlelight, creating a warm and relaxing atmosphere that helps guests fall asleep; the 5W power ensures sufficient lighting brightness (approximately 400 lumens) while achieving low energy consumption, in line with environmental protection principles; the adjustable brightness design allows users to precisely adjust the light intensity through a knob or APP according to specific activities (such as reading, talking, or resting) and personal preferences, meeting personalized needs.

[0029] In one embodiment, the inner diameter of the acrylic sheet 10 is smaller than the diameter of the top opening of the first lampshade 6, thus forming a purified air output channel. The acrylic sheet 10 both supports the air filter device 9 and allows light to pass upward, achieving the coexistence of lighting and airflow channels. The purified air is discharged from the top after releasing negative ions through the negative ion generator, improving air freshness. The air intake surface of the small turbine fan faces downward, used to draw ambient air into the interior of the first lampshade 6 and upward through the air filter device 9. The outer diameter of the acrylic sheet 10 matches the top of the inner wall of the first lampshade 6, and the inner diameter is smaller than the opening of the first lampshade 6, thus forming a ring in the central area. Air output channel; the solid part of the acrylic sheet 10 supports the air filter device 9 and the negative ion generator upwards, ensuring structural stability; at the same time, its frosted surface can effectively diffuse the light transmitted upwards from the first light source 7 (E27 bulb), allowing some light to gently overflow from the top, increasing ambient brightness; the annular channel allows clean air purified by the filter and carrying negative ions to be smoothly discharged from the top; the air inlet of the small fan device 8 faces downwards, forming an upward airflow path with the air outlet facing upwards. This conforms to the natural law of hot air rising, which can circulate indoor air more efficiently and avoid blowing dust directly up from the ground, causing secondary pollution.

[0030] In one embodiment, the second lampshade 3 is a milky white acrylic translucent lampshade, serving as an auxiliary lampshade. The second lampshade 3 is smaller than the first lampshade 6, and its top is connected to the center of the bottom of the first lampshade 6 via a snap-fit ​​or threaded structure. The second light source 5 has a power of 12W, a length of 1 meter, and a color temperature of 3000K. It is arranged around the inside of the second lampshade 3, providing a soft, ring-shaped halo for auxiliary ambient lighting. The size difference between the second lampshade 3 and the first lampshade 6 (the first lampshade 6 is larger) not only creates a sense of layering visually but also functionally distinguishes between primary and secondary lighting. The second lampshade 3 is located in the middle layer, and its main function is to provide ambient lighting. The LED light strip (usually a high color rendering index CRI>80) is installed around the inner wall, producing a 360° uniform ring halo that illuminates the area around the countertop, creating a warm and comfortable guest room environment. It is especially suitable for use at night as a low-brightness night light or background light, avoiding the unease caused by complete darkness. The 3000K warm light color temperature is consistent with the first light source 7, ensuring a harmonious and unified lighting environment. The connection method (snap or thread) at the top center is not only structurally stable, but also effectively guides the purified air exhausted from the first lampshade 6 to flow through the outside of the second lampshade 3, forming an airflow barrier and reducing the adhesion of dust to the surface of the second lampshade 3.

[0031] In one embodiment, a metal weight 12 is embedded inside the metal base 1. The bottom of the metal base 1 is encapsulated by a tablecloth cover 13, which is made of non-slip silicone with an elastic edge structure to conceal the seam between the adjustable power cord 11 and the metal base 1, improving aesthetics and dustproof performance. The adjustable power cord 11 is connected to the right end of the metal base 1. The metal support rod 2 is made of high-strength aluminum alloy and anodized. Two small speaker devices 4 are symmetrically distributed, which are flat stereo speakers that support Bluetooth 5.0 and above or Wi-Fi wireless connection and can play background music, voice prompts, or hotel service information. The intelligent control module supports remote control via APP, voice commands, and physical knob operation. It is used to receive local trigger signals or remote control commands from smart terminals or hotel management systems via Bluetooth / Wi-Fi to achieve integrated intelligent operation of lighting, purification, and music. The embedded metal weight 12 (such as cast iron or stainless steel) increases the overall weight and center of gravity stability of the metal base 1. Effectively prevents the lamp body from tipping over due to accidental collisions or slight vibrations from the fan, ensuring safe use; the tablecloth bottom cover 13 is made of anti-slip silicone material, and its anti-slip texture on the bottom increases friction with the table surface, further preventing slippage; the elastic structure at the edges tightly wraps around the bottom of the base, hiding the power cord interface and wiring, keeping the table surface clean and beautiful, while preventing dust from entering the interior from the bottom gaps; the metal support main rod 2 is made of high-strength aluminum alloy, balancing structural strength and lightweight, and the anodizing treatment enhances surface hardness, wear resistance, and a high-end metallic texture; two flat small speaker devices 4 are symmetrically installed to form a stereo sound field with clear sound quality, meeting the needs of playing background music or hotel announcements; the integration of the intelligent control module is the core of intelligence, allowing users to perform basic operations through the physical knobs on the lamp body, or to remotely and precisely control it through a mobile APP (such as setting timer switches, viewing historical air quality data), or to achieve hands-free operation through voice assistants (such as Xiao Ai or Siri), improving the user experience and the level of intelligence in hotel rooms.

[0032] In one embodiment, the air filter device 9 is a detachable cylindrical structure, which facilitates user maintenance. It includes a primary filter, a HEPA high-efficiency filter, and an activated carbon filter layer arranged sequentially from bottom to top, for multi-stage filtration of pollutants such as PM2.5, dust, pollen, odors, and formaldehyde. The outer periphery of the air filter device 9 forms a seal with the inner wall of the first lamp cover 6, and the bottom of the air filter device 9 is supported and fixed by an acrylic sheet 10. The primary filter is a washable metal mesh cover. The bottommost primary filter (washable metal mesh) first intercepts hair, large dust particles, and fibers, protecting the upper precision filter. It is washable and reusable, reducing maintenance costs. The HEPA high-efficiency filter and activated carbon filter layer are replaceable. The middle HEPA high-efficiency filter (H13 level) can effectively capture more than 99.95% of particles with a diameter of 0.3μm, including PM2.5. The activated carbon filter layer uses columnar coconut shell activated carbon to effectively adsorb gaseous pollutants and odors such as formaldehyde, benzene compounds, and TVOCs, due to its large specific surface area and well-developed microporous structure. The top of the air filter element 9 has an integrated handle structure, and the side wall has a rotating buckle that matches the groove on the inner wall of the first lamp cover 6, enabling quick installation and removal. The combination of the rotating buckle and the groove, along with the top handle, allows users to easily install, remove, and replace the filter element with one hand. The bottom of the air filter element 9 has a sealing ring that forms a sealed connection with the acrylic sheet 10 to prevent unfiltered air leakage. The bottom sealing ring ensures that the airflow must pass through the filter element 100%, guaranteeing purification efficiency. This design makes the filter element maintenance simple and low-cost, making it very suitable for the needs of hotels for batch management and rapid replacement.

[0033] In one embodiment, the negative ion generator is positioned immediately adjacent to the clean air output side of the air filter device 9. Placing the negative ion generator after the filter ensures that the released negative ions only affect the already purified clean air, preventing negative ions from combining with pollutants and settling on the filter, thus avoiding impact on filter life and purification efficiency. Pulsed DC high-voltage corona discharge technology is used to release negative ion concentrations of... It effectively settles 0.3-10μm suspended particulate matter in the air and inhibits the activity of bacteria and viruses. It adopts pulsed DC high-voltage corona discharge technology, which can more accurately control the discharge process compared with traditional AC technology. While generating high concentration of negative ions, it strictly controls the concentration of ozone byproducts within the safety standard (<0.05ppm) to protect the health of guests. The negative ion concentration is much higher than the average level in urban indoor environments (about 100-500 ions / cm³), approaching the level of forest environments. It can effectively charge positively charged particles such as dust, bacteria, and viruses in the air, causing them to aggregate and settle, further improving air cleanliness and making people feel refreshed and clear-headed. The negative ion generator and the small fan device are linked to start and stop in 8-step operation, saving energy and avoiding ozone generation. The design linked with the fan prevents the negative ion generator from running idle when the fan stops, which saves energy and extends the generator's lifespan.

[0034] In one embodiment, the acrylic sheet 10 is a frosted annular structure with a thickness of 4mm and a light transmittance of ≥90%. The 4mm thickness ensures sufficient mechanical strength to support the weight of the filter element without excessively increasing the height of the lamp body. The ≥90% light transmittance ensures that the light from the first light source 7 can efficiently penetrate upwards. The frosted surface has excellent diffuse reflection effect, which can evenly and softly diffuse the light emitted by the point light source, avoiding the formation of glaring bright spots or shadows, making the light overflowing from the top soft and improving the overall comfort of the lighting environment. The outer diameter matches the inner wall of the first lampshade 6, and the central opening allows airflow to pass through, which not only evenly diffuses the light from the first light source 7 and ensures unobstructed airflow, but also provides stable support for the air filter device 9.

[0035] In one embodiment, the intelligent control module integrates a PM2.5 sensor, a TVOC sensor, and a temperature and humidity sensor to collect environmental data in real time. The air quality level (excellent / good / lightly polluted / moderately polluted) is displayed via RGB LED indicators or a mobile app. The PM2.5 sensor monitors the concentration of inhalable particulate matter in real time, the TVOC sensor monitors the levels of volatile organic compounds such as formaldehyde and benzene, and the temperature and humidity sensor provides a reference for environmental comfort. Based on this data, the intelligent control module calculates the Integrated Air Quality Index (IAQ) using a preset algorithm and displays it using different colors of RGB LEDs. LED indicator lights provide intuitive display (e.g., green - excellent, yellow - good, orange - light pollution, red - moderate pollution); when pollutant concentration exceeds the standard, the system automatically activates a powerful purification mode and sends a push notification via the app. When the detected pollutant concentration exceeds a preset threshold (e.g., PM2.5 > 75 μg / m³), the system automatically switches the fan to "powerful mode" and activates the negative ion generator, quickly improving air quality without user intervention. Simultaneously, via Wi-Fi or Bluetooth, the system sends push notifications to guests' mobile apps or the hotel management system, informing them of the current air quality status and filter replacement reminders, enabling proactive health management and enhancing the refinement and intelligence of hotel services.

[0036] A purification method using an environmentally friendly light fixture with air purification function, comprising the following steps: S1: Power is turned on via the adjustable switching power supply line 11. The intelligent control module starts the self-test program and initializes the lighting, fan, audio and sensor modules. S2: The small fan device 8 draws in indoor air from the bottom of the first lamp cover 6, and first passes through the lower primary filter to intercept large particulate impurities; S3: Driven by the fan, the drawn-in air passes through the detachable air filter device 9, and then through a triple filtration process: a primary filter, a HEPA high-efficiency filter, and an activated carbon filter layer. Particulate pollutants such as dust, pollen, and PM2.5 in the air are effectively intercepted and adsorbed by the filter, while gaseous pollutants such as VOCs are adsorbed by the activated carbon. S4: Clean air passes through the negative ion generator area and is injected with a high concentration of negative ions, which further inactivate viruses and settle micro-dust. S5: Fresh air rich in negative ions is evenly discharged from the air outlet at the top of the lamp body, forming an airflow circulation from bottom to top, avoiding secondary dust; S6: The intelligent control module dynamically adjusts the fan speed, negative ion intensity, lighting brightness, and sound status based on sensor data; S7: When the filter element resistance increases or the usage time reaches the threshold, the system will remind the user to disassemble, clean or replace the air filter element via APP or indicator light 9; S8: While providing main and auxiliary lighting, it continuously purifies the air and plays background music, achieving multiple uses with one lamp. It replaces traditional table lamps and independent air purifiers, significantly reducing hotel equipment procurement, storage, and space occupancy costs.
