Description

Technical Field

[0001] The present invention relates to the field of ship lighting, and in particular, to an intelligent cabin lamp with a manual control function. Background Art

[0002] As a special surface building, there are not many differences in the design and research methods of the light environment in the internal cabins of ships compared with the indoor light environment design. Due to problems such as power or resource reserves in early ships, the lighting fixtures in the cabins were often restricted. When a ship sails at night, in order to avoid the serious "black window effect" in the cabin, which affects the ship's ability to observe the external environment and reduces navigation safety. The cabins of ships often only use weak light illumination, and the visual ability of sailors in a weak light environment will decrease significantly, affecting the accuracy of sailors' operations and judgments, and then causing misoperation behaviors, posing a serious threat to the safety of the ship.

[0003] As one of the main design improvement objects of the cabin light environment, its design level will affect the visual performance and visual comfort of sailors, and then affect the operation quality of sailors.

[0004] Conventional lamps have a switch function, controlling several lamps simultaneously on one line. Single lamps do not have independent adjustment and do not have a remote control function. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem that single lamps in the prior art do not have independent adjustment, and to provide a new type of intelligent cabin lamp with a manual control function.

[0006] To achieve the above invention purpose, the present invention provides an intelligent cabin lamp with a manual control function, including: an LED light source board and a light-transmitting diffusion board on the light-emitting side of the LED light source board. The LED light source board has two different color temperature LED chips controlled in a PWM manner. Among them, the total power of each color temperature LED chip can meet the requirements of the rated luminous flux; preferably, it further includes: a manual control switch, which is used to turn on and off the lamp, and / or adjust the color temperature or brightness of the lamp.

[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings through specific embodiments. It should be noted here that the description of these embodiments is for helping to understand the present invention, but does not constitute a limitation to the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0015] Please refer to Figure 1 , which shows an intelligent cabin lamp with manual control function.

[0016] The intelligent cabin light includes: a lamp housing 1, an LED light source board 2, a light-transmitting diffuser plate 3, etc. The LED light source board 2 has LED chips of two color temperatures. The LED chips of the two color temperatures are arranged evenly and staggeredly. The LED light source board 2 uses direct-downward light emission, and the light emission through the light-transmitting diffuser plate 3 further limits the surface brightness of the lamp while meeting the luminous flux index, avoiding discomfort glare and reducing the blue light radiation intensity.

[0017] The basic conditions of the LED light source board 2 are as follows: First, the total power of the LED chips of each color temperature can meet the requirement of the rated luminous flux, that is, the rated luminous flux of the LED light source board 2 is twice that of traditional LED lamps. Second, the working current of the LED chips is controlled by the PWM method, and the approximate linear relationship between the working current of the LED chips and the luminous flux is used to realize the ratio of the luminous fluxes of different color temperatures.

[0018] The dimming methods of the LED light source board 2 include: 1) The color temperature can be continuously adjusted while the brightness of the lamp remains unchanged: This is achieved by changing the light flux ratio of the two types of LED chips. Specifically, when the total light flux remains unchanged (the brightness remains unchanged), the light flux of one type of LED chip decreases while the light flux of the other type of LED chip increases correspondingly (i.e., the light flux shifts from one end to the other end). 2) The brightness can be continuously adjusted while the color temperature of the lamp remains unchanged: This is achieved by adjusting the light fluxes of the two types of LED chips with different color temperatures in equal proportion. Specifically, when the light flux ratio of the two color temperatures remains unchanged, the light fluxes of the two types of LED chips increase or decrease simultaneously in equal proportion and the sum of the light fluxes shall not exceed the rated light flux. 3) The lamp automatically adjusts its light intensity in sequence according to the preset program of the lighting control device: This is achieved by presetting the dimming program in the control device. Specifically, considering the demand for automatic dimming by time period and the visual continuity requirement of color temperature change, the technical indicators are segmented into a series of target values to be controlled according to time periods, and then the preset program plays the target commands according to time. The target commands are converted into direct control commands (the percentage of current output of the two types of LED chips) by the arithmetic processor and then output to the lamp communication control unit through the bus. The intelligent cabin lamp further includes: a manual control switch 4. The manual control switch 4 is fixed on the lamp housing or the light-transmitting diffuser plate. The user can control the on / off of the lamp through the manual control switch 4, and / or adjust the brightness or color temperature of the lamp. In some embodiments, the control method of the manual control switch is configured as follows: When it is sampled that the manual control switch is clicked once, it switches to the on / off adjustment mode of the lamp (for example, click once, the lamp turns on, click again, the lamp turns off). When it is sampled that the manual control switch is double-clicked, it switches to the color temperature adjustment mode or the brightness adjustment mode of the lamp (for example, double-click once, enter the color temperature adjustment mode, double-click again, enter the brightness adjustment mode). If it is sampled that the manual control switch is long-pressed in the color temperature adjustment mode, the color temperature of the lamp changes from low to high; then, if it is sampled that the manual control switch is released and then long-pressed again, the color temperature of the lamp changes from high to low. If it is sampled that the manual control switch is long-pressed in the brightness adjustment mode, the brightness of the lamp changes from low to high; then, if it is sampled that the manual control switch is released and long-pressed again, the brightness changes from high to low.

[0019] The intelligent cabin light further includes: a remote control interface. Through the remote control interface, remote control of the intelligent cabin light is achieved. Specifically, a centralized communication method can be adopted. The software on the PC side of the centralized control center sends query and dimming commands to all cabin lights via a bus. After the control device parses the commands, it dims or queries the lights. The bus encodes the addresses of the cabin lights through address-based communication. The control device only needs to uniformly send control commands to all lights according to the address codes, and distributes the control signals to the control execution units in each light through the bus. Finally, the execution unit parses the control signals and uses the method of PWM to control the effective value of the current to complete the precise output of the LED light source.

[0020] The intelligent cabin light issues corresponding control commands according to the preset program and external trigger signals, and sends them to the internal control module of the light in the form of a bus. Finally, the light executes the change of light output. When the intelligent cabin light does not receive a control signal or the control signal is abnormal, the intelligent cabin light executes the preset default program to maintain lighting.

[0021] Please refer to Figure 2 and Figure 3 , the intelligent cabin light can have the following functions: 1. Lighting control board function: Receive data signals such as the "lighting control board" status signal, mode, brightness, lock, and time sent by the lighting control board. The light calls the data in the storage chip according to its address code and executes it.

[0022] 2. Data download function: Download and update the data on the storage chip of the light. The host computer sends the "data download" status signal, address code, and PWM data in various modes corresponding to each address. Each light receives the corresponding PWM data according to its address code and downloads it into the storage chip.

[0023] 3. Data debugging function: Perform real-time debugging on the light. The host computer sends the "data debugging" status signal, debugging mode, address code, and PWM data corresponding to each address. Each light receives the corresponding PWM data according to its address code and executes the received PWM data in real time. This data is not written into the storage chip.

[0024] The microprocessor calls the corresponding data according to the light address set by the encoder, processes the communication data signals received by the bus, and then sends them to the CPLD through the bus to control the CPLD to generate corresponding PWM signals for the LED driver circuit.

[0025] The above only expresses the embodiments of the present invention, which are described in a relatively specific and detailed manner. However, it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
