The controller controls the lighting effect of the lighting module 30 according to the detection signal of the angle sensor, and the controller also controls the lighting effect of the lighting module 30 according to the trigger signal of the button module 50.

[0044] A control method for a ceiling lighting device includes:

[0045] Obtaining a rotation angle of a handrail 20 that is rotated and arranged on the roof of a vehicle;

[0046] When the rotation of the armrest 20 meets a predetermined condition, the lighting effect of the lighting module 30 disposed in the car is changed;

[0047] When there are multiple operations for changing the lighting effect of the lighting module 30 , only the rotation angle of the armrest 20 is acquired.

[0048] Further, the predetermined conditions include any of the following: releasing after pulling down the handrail 20, releasing after pressing the handrail 20, maintaining for a period of time before releasing after pressing the handrail 20, and pulling down the handrail 20 to the limit position at least twice within a specified time.

[0049] Furthermore, the change of the lighting effect includes any of the following situations: lighting up the light, turning off the light, adjusting the light brightness, changing the light color, and changing the light color in a cycle. Specifically, the change of the lighting effect includes any of the following situations:

[0054] (5) The light color changes cyclically. Specifically, the current light color changes to white, and then changes in the order of white-red-green-yellow-blue-pink-white. Each color lasts for at least 0.5 seconds.

[0055] In order to explain the control method of the ceiling lighting device in detail, further discussion will be given below in combination with the ceiling lighting device.

[0056] See also Figure 4 , Figure 4 It is a flow chart of the control method of the ceiling lighting device described in the first embodiment.

[0057] First, when the ceiling lighting device is in an initial state, the armrest 20 is retracted and the lighting module 30 is disconnected from the power supply.

[0058] Then, pull the handrail 20 downward and release it, the downward angle is 10 to 30 degrees, such as Figure 5 As shown, Figure 5 The dotted line in the figure is the position of the armrest 20 in the initial state. At this time, the lighting module 30 is connected to the power supply, and the light brightness of the lighting module 30 gradually changes from off to a predetermined brightness. The light color of the lighting module 30 is white.

[0059] Next, press the armrest 20 upward and release it, the pressing angle is greater than or equal to 2 degrees, such as Figure 6 As shown, Figure 6The dotted line in the figure is the position of the armrest 20 in the initial state. At this time, the light color of the lighting module 30 changes from white to red. According to the number of times the armrest 20 is pressed, the light color of the lighting module 30 can change from white to red, green, yellow, blue, pink and then back to white.

[0060] During this period, the brightness of the lighting module 30 can be changed by pulling down the armrest 2010 to 30 degrees and then releasing it, and the light brightness can be set to 0, 1, 2, and 3 levels, where 0 is off, 1 is the darkest, 2 is medium, and 3 is the brightest. According to the number of times the armrest is pulled down, the brightness level of the lighting module 30 can be increased from the current brightness level to level 3, and then cycled through levels 3-1-2-3-1-2..., where if the current brightness is level 3, it is adjusted from level 3 to level 1, and then cycled through levels 1-2-3-1-2-3...

[0061] In addition, during the above process, the armrest 20 can be pressed upwards and the pressing state can be maintained for at least 2 seconds to start the light color cycle change mode of the lighting module 30, that is, the light color of the lighting module 30 is changed from the current color to white, and the color is cycled in white-red-green-yellow-blue-pink-white..., and each color lasts for about 0.5 seconds. If the current color is white, it is changed to red, and the color is cycled in red-green-yellow-blue-pink-white-red...

[0062] Finally, pull the handrail down to the limit position twice within 3 seconds. The pull-down angle is generally 90 to 180 degrees. Figure 7 As shown, Figure 7 The dotted line in the figure is the position of the armrest 20 in the initial state. At this time, the lighting module 30 is disconnected from the power supply, and the light brightness of the lighting module 30 gradually changes from the current brightness to off.

[0063] Embodiment 2

[0064] A ceiling lighting device, see Figure 8 and 9 The difference between the ceiling lighting device described in the first embodiment and the embodiment 1 is: a metal ring 41, a local conductive ring 42, a first conductive member 43, and a second conductive member 44.

[0065] The metal ring 41 is arranged on the end face of the base 10 close to the armrest 20, and the center of the metal ring 41 is located at the same point as the rotation point of the armrest 20. The local conductive ring 42 is arranged on the end face where the metal ring 41 is located, and the local conductive ring 42 is concentric with the metal ring 41. The local conductive ring 42 is provided with a plurality of conductive areas 45 and non-conductive areas 46 arranged between adjacent conductive areas 45, and the conductive areas 45 and the non-conductive areas 46 are distributed on the local conductive ring 42 around the center of the local conductive ring 42. The first conductive member 43 is arranged on the armrest 20, and the first conductive member 43 is electrically connected to the metal ring 41. Specifically, the first conductive member 43 is a contact spring, and the first conductive member 43 abuts against the metal ring 41. The first conductive member 43 moves on the end face of the metal ring 41 around the center of the metal ring 41. The second conductive member 44 is disposed on the armrest 20 , and is electrically connected to the local conductive ring 42 . Specifically, the second conductive member 44 is a contact spring, and the second conductive member 44 abuts against the local conductive ring 42 . The second conductive member 44 moves on the end surface of the metal ring 41 around the center of the metal ring 41 .

[0066] The armrest 20 is driven to rotate. When the second conductive member 44 contacts the conductive area 45, the current sequentially passes through the metal ring 41, the first conductive member 43, the second conductive member 44, and the local conductive ring 42 and then flows to the controller. The controller changes the lighting effect of the lighting module 30 provided in the car. When the second conductive member 44 contacts the non-conductive area 46, the controller does not change the lighting effect of the lighting module 30 provided in the car.

[0067] Embodiment 3

[0068] A control method for a ceiling lighting device, see Fig.10 The difference between the control method of the ceiling lighting device described in Example 1 is that the lighting effect also includes light flickering. Specifically, the brightness of the light changes from the current brightness to off, and then from off to the current brightness, and changes in this cycle.

[0069] In order to explain the control method of the ceiling lighting device in detail, the following further discusses the ceiling lighting device described in the first embodiment.

[0070] See also Fig.10 , Fig.10 It is a flow chart of the control method of the ceiling lighting device described in the first embodiment.

[0071] First, when the ceiling lighting device is in an initial state, the armrest 20 is retracted and the lighting module 30 is disconnected from the power supply.

[0072] Then, pull the handrail 20 downward and release it, the downward angle is 10 to 30 degrees, such as Figure 5 As shown, Figure 5 The dotted line in the figure is the position of the armrest 20 in the initial state. At this time, the lighting module 30 is connected to the power supply, and the light brightness of the lighting module 30 gradually changes from off to a predetermined brightness. The light color of the lighting module 30 is white.

[0073] Next, press the armrest 20 upward and release it, the pressing angle is greater than or equal to 2 degrees, such as Figure 6 As shown, Figure 6 The dotted line in the figure is the position of the armrest 20 in the initial state. At this time, the light color of the lighting module 30 changes from white to red. According to the number of times the armrest 20 is pressed, the light color of the lighting module 30 can change from white to red, green, yellow, blue, pink and then back to white.

[0074] During this period, the brightness of the lighting module 30 can be changed by pulling down the armrest 2010 to 30 degrees and then releasing it, and the light brightness can be set to 0, 1, 2, and 3 levels, where 0 is off, 1 is the darkest, 2 is medium, and 3 is the brightest. According to the number of times the armrest is pulled down, the brightness level of the lighting module 30 can be increased from the current brightness level to level 3, and then cycled through levels 3-1-2-3-1-2..., where if the current brightness is level 3, it is adjusted from level 3 to level 1, and then cycled through levels 1-2-3-1-2-3...

[0075] In addition, during the above process, the light flashing mode of the lighting module 30 can be started by pressing the armrest 20 upwards and maintaining the pressing state for at least 2 seconds, that is, the brightness of the light quickly changes from the current brightness to off, and then quickly changes from off to the current brightness, and changes in this cycle, wherein the duration of the current brightness is 0.5 seconds, and the duration of the off is 0.5 seconds.

[0076] Moreover, when the lighting module 30 is in the light flashing mode, the armrest 20 is pressed upward again and the pressing state is maintained for at least 2 seconds, the lighting effect of the lighting module 30 can be switched to the light color cycle change mode, that is, the light color of the lighting module 30 is changed from the current color to white, and the color is cycled in sequence of white-red-green-yellow-blue-pink-white..., and each color lasts for about 0.5 seconds. Among them, if the current color is white, it is changed to red, and the color is cycled in sequence of red-green-yellow-blue-pink-white-red...

[0077] Finally, pull the handrail down to the limit position twice within 3 seconds. The pull-down angle is generally 90 to 180 degrees. Figure 7 As shown, Figure 7 The dotted line in the figure is the position of the armrest 20 in the initial state. At this time, the lighting module 30 is disconnected from the power supply, and the light brightness of the lighting module 30 gradually changes from the current brightness to off.

[0078] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
