technical field

The utility model relates to a ceiling lamp, in particular to a voice control LED ceiling lamp system.

Background technique

With the advancement of my country's market economy, my country has entered a stage of accelerated industrialization and urbanization, and the total energy demand continues to increase. The problem of tight resource supply facing economic development has long existed, the most prominent of which is power supply. As we all know, my country is a power generation power second only to the United States, and 80% of it is thermal power generation. Thermal power generation burns a large amount of coal and oil every day, and produces a large amount of harmful gases, polluting the environment. In today's environment where energy conservation and environmental protection are generally advocated in the world, saving energy and vigorously promoting the efficient use of energy is the fundamental way out to alleviate the energy shortage. In the current environment where countries are vigorously advocating energy technology innovation, energy conservation and improving energy utilization efficiency in order to alleviate energy shortages, a new type of energy-saving and environmentally friendly light source that is gradually becoming mature with the continuous advancement of technology-semiconductor light-emitting diodes ( LED for short) is gradually used in lighting products, injecting new vitality into the development of green lighting, and also making the concept of energy saving and environmental protection prominent in the lighting field.

At present, my country's lighting consumption accounts for about 20% of the total power consumption. Although some methods have been used to reduce lighting power consumption, there is still a long way to go before we advocate "green lighting". In European and American countries, 55% of incandescent lamps and 55% of fluorescent lamps have been replaced by LEDs, saving 35 billion US dollars in electricity bills and reducing 755 million tons of carbon dioxide emissions each year. In Japan, 90% of incandescent lamps are replaced by LEDs, which can reduce the power generation of 1-2 nuclear power plants and save more than 1 billion liters of crude oil consumption every year. With the rapid development of LED technology and the gradual improvement of its luminous efficiency, the application market of LED will be more extensive. Especially in the context of rising concerns about global energy shortages, the prospect of LED in the lighting market has attracted global attention. The industry believes that in the next 10 years, it will become the most promising market and the largest market will be the product with the greatest potential to replace incandescent lamps, tungsten lamps and fluorescent lamps.

It is a recognized fact in the lighting industry that LED light sources are used for lighting to achieve energy-saving effects. LED devices are cold light sources with high luminous efficiency, low operating voltage, low power consumption, and small size. The ceiling lamp developed with it has a simple structure , light weight, strong and long life, the light source itself does not contain mercury, lead and other harmful substances, no infrared and ultraviolet pollution, will not produce pollution to the outside world during production and use. And under the same brightness, the energy consumption of the whole lamp is only 1/10 of that of ordinary incandescent lamps, and 1/5 of that of fluorescent lamps, while the life span can be extended by 100 times. As a new product of the fourth-generation light source, high-energy-efficiency LED lighting has covered all parts of urban daily life, and its application fields are constantly expanding.

At present, although street lights, flood lights, wall washers and other lighting decoration LED lights that use LEDs as illuminants have sprung up in the past one or two years in the domestic and foreign markets, LED devices are used as ceiling light sources. There are still very few so far, and the use of voice recognition systems for switch control in ceiling lamps has never been seen in domestic and foreign markets. And its control installation method will also achieve new improvements with the application of new materials and new technologies, so the promotion of LED ceiling lights based on voice recognition control in the field of indoor lighting will also be imperative.

Now all ceiling lamps in the domestic and foreign markets use incandescent lamps or energy-saving lamps as light sources, which determines that the shape and structure of the lamps must be quite large to be able to accommodate such a large light source as incandescent lamps or energy-saving lamps. Moreover, the shapes of incandescent lamps and energy-saving lamps themselves are fixed, so it is determined that the shapes of lamps produced by most manufacturers basically do not change much. Their structures are single and have no own characteristics. The appearance is similar, and the functions are similar. There is no new breakthrough in the shape design of the whole lamp, so the sales price of the ceiling lamp has been unable to rise, and even the sales price of the new product that has just come out may not be as good as the old one. The price of the product. In addition, the life of incandescent lamps and energy-saving lamps is too short, the luminous efficiency is low, the power consumption is large, the stability of the mains voltage is relatively high, and they are easily damaged by the fluctuation of the power grid, so that users need to maintain and replace frequently, which increases the cost for users. added cost and hassle. Secondly, all kinds of ceiling lamps on the market we have come into contact with are also traditional control methods and installation methods. You can turn on and off the light beside the bed, and you can turn on and off the same light at the bedside or by infrared remote control. These methods not only increase the cost, but also have certain requirements for the wiring and installation location selection during the project. It is very inconvenient for the user to have to find the switch installed on the wall or the infrared remote control panel that is placed there casually, and even get up to turn off the light when sleeping at night, although it is just such a It's a small movement, but how unwilling it is to get up to turn off the lights when people are lying in bed in cold winter or hot summer. Finally, in terms of installation methods, all the ceiling lights on the market are installed against the wall, and protrude from the wall, so that the feeling of the small living space will become smaller , and even give people a feeling of depression, so that users cannot experience the spaciousness of the room.

The description of the function of each development process of the voice control LED ceiling light system, the research solution and the direction of development are as follows:

1. The development of the voice control circuit and the programming of the single-chip microprocessor program: the received human voice commands are collected through the voice integrated circuit in advance, and then the data is sorted and stored by the single-chip microprocessor, and then the random The received voice command is compared with the preset command, and if the command is consistent, the corresponding command is output through the single-chip microprocessor to execute the operation originally set relative to the command.

2. Development of constant voltage switching power supply: The switching power supply adopts a monolithic isolated constant voltage power supply circuit with a wide input voltage range of 85-265VAC. The power supply meets the technical requirements of lightning surge, harmonics, conduction and electromagnetic compatibility, etc. The impact of mains power. At the same time, its wide range (85-265VAC universal input) input voltage also ensures that it will not be affected by the fluctuation of the grid voltage during the peak period of power consumption, so that the output of the lamp is always constant. Traditional lamps The brightness of the lamp flickers unstable with the fluctuation of the grid voltage, and if the fluctuation of the grid power is too large and far exceeds the rated voltage of the lamp, the bulbs in it will be easily burned out due to excessive current.

3. Development of LED constant current circuit with PWM adjustable: Because the LED device is a current component, it has high requirements on the stability of the current, so the quality of the constant current circuit directly affects the stability of the LED work Performance. We use PWM switches with high sensitivity, fast conversion speed, small input and output pressure difference, good thermal stability, and integrated circuits with PWM adjustment ports to drive LED lamp beads.

4. Design of the overall cooling block of the LED module: Since LED devices are usually sensitive to heat, the heat caused by long-term work will bring stability and service life problems. Therefore, we choose copper with high thermal conductivity (thermal conductivity 200~400w/m.k) as the PCB heat dissipation substrate of the LED module. It is also necessary to design a heat dissipation plate specifically for the LED illuminant of this product. The design of the heat dissipation plate fully considers heat dissipation The form effectively combines conduction and air circulation to ensure the heat dissipation of the LED. The thermal conductivity of the lamp body is aluminum, which is next to copper, and the two are closely matched during assembly, so that the lamp body can fully play the role of auxiliary heat dissipation.

5. Design of the ceiling lamp housing and lampshade: Through computer modeling, the secondary light distribution of the lampshade of the ceiling lamp is more uniform and soft. Through the surface technology of the lampshade, the string light in the light irradiated by the lamp is fully and less, The lampshade is made of imported PC material, which is resistant to beating, has good light transmission effect, no attenuation, good light concentrating effect, and longer radiation distance. The lamp housing of the ceiling lamp is made of integral aluminum die-casting, which reduces the number of spare parts and makes the structural integrity of the lamp better. Because the assembly of some parts is reduced, it also avoids the vibration of the lamp during transportation. loosening or falling off.

6. The design of the ceiling lamp installation bracket: In the design process of the ceiling lamp, the installation method of the lamp is fully considered, and the design method of both the ceiling installation and the embedded installation is adopted at the same time, so that users can according to their own houses. Features to choose the installation method that suits your own house.

First of all, this product uses energy-saving and environmentally friendly LEDs as light sources, which makes this product different from other similar products in essence, and compared with other traditional ceiling lamps after using LED light sources, the ceiling lamps have the same power at the same time Under the environment, its energy consumption is only 10-30% of traditional lamps. While incandescent lamps, fluorescent lamps, and halogen lamps use electron radiation to emit light, the filament is easy to burn, and has characteristics such as thermal deposition. Moreover, the use of LED as the light source in the ceiling lamp makes the whole lamp have a long life, easy to control, maintenance-free, safe and environmentally friendly, and greatly reduces maintenance costs. Coupled with a wide range of voltage, the light source can realize various color changes of the LED through the built-in controller of the microcomputer, and can also realize voice dimming, and the light color is soft, bright and colorful. In addition, LED is a solid light source, and the ceiling lamp made of it can also withstand mechanical shock and high-intensity vibration, thereby improving the safety of product transportation and reducing product damage during transportation.

Secondly, the application of voice recognition system in LED ceiling lamp products has brought users a new concept of remote control lighting switch, which has never appeared in the domestic and foreign markets. Compared with traditional manual control and infrared The control is more convenient and flexible. The product provides users with dozens of voice commands. You just need to say "turn on the light" or "turn off the light" at any place in the room, and the lamps will automatically turn on or off. You touch the switch on the wall at night when you can’t see your fingers, or look for the remote control board everywhere. You just need to say a word and move your mouth to realize it. This product fully embodies the concept of pursuing people-oriented, especially suitable for fashion home decoration and Places where special groups such as the elderly and children/disabled people live and live. The main voice commands of the product are:

Voice command Ceiling light status

"Turn on the light" Turn on the light

"Lights off" Lights off

"Cold light" The lamp emits white light with a color temperature of 6400K

"Warm Light" The lamp emits warm light with a color temperature of 2700K

"Dimming" The lighting changes continuously from bright to dark

"Pause" The lamp is in the state of dimming or changing color after you issue a voice command

                             

"Colour-changing" lamps and lanterns will emit red, green, blue three basic colors according to a

A color formed by regular combinations

"Cancel" The lamp will automatically cancel the current pause command

Thirdly, because the LED is a solid light source that is not easy to break and is impact-resistant, the design structure of the ceiling lamp is no longer limited to the traditional shape and installation mode, and in order to facilitate the heat dissipation of the LED, the LED we designed uses the overall aluminum The lampshade is made of alloy shell and imported PC material, abandoning the traditional plastic shell, and the surface of the lamp shell is treated by special metal processing technology, which not only improves the overall firmness of the lamp, but also improves the overall appearance of the lamp. The heat dissipation effect of the light source is improved, and the service life of the lamp is improved. Also, because the volume of the LED light source is relatively small, the overall thickness of the LED ceiling we designed is less than 6CM, so that our LED ceiling lamp can be installed in the ceiling or embedded. Luxurious and stylish, it adopts a new embedded installation method, which avoids the defect that the short room cannot be equipped with large and luxurious lighting, and also maintains the ceiling installation of the ceiling lamp itself. Therefore, the new LED ceiling lamp is suitable for long-term lighting in shopping malls, banks, hospitals, hotels, restaurants and other public places. The novel and ultra-thin shape structure can also beautify the indoor environment.
