The present invention provides a lamp, comprising a lampshade 1, a base 2 on which a light source assembly 101 is fixed, and a controller.

The lampshade 1 of the lamp is sleeved and rotatably connected to the base 2, and between the lampshade 1 and the base 2 there is also a floating pressing component for realizing the floating of the two in the axial direction. Rotation can also float up and down relative to the base 2 under the action of the floating pressing component.

The lampshade 1 is connected with a rotary encoder 103, and the rotary encoder 103 is used to obtain the rotation angle of the lampshade 1, including the rotation direction and the angle. Under different motion states of the lampshade 1 , the controller adjusts the functions and parameters of the lamp according to the signals obtained by the rotary encoder 103 .

The controller includes a first control circuit connected to the light source assembly 101 , and the first control circuit is used to adjust the performance parameters of the light source assembly 101 according to the signal obtained by the rotary encoder 103 . It should be noted that the aforementioned first control circuit does not refer to the power supply of the light source assembly 101 , but refers to a control circuit for adjusting the performance parameters of the light source assembly 101 , such as brightness.

As for the adjustment method of the lamp, when the lampshade 1 is in the first pressing state, the floating pressing component connects the first control circuit with the rotary encoder 103, and at this time, rotating the lampshade 1 can adjust the performance parameters of the light source assembly 101, for example, clockwise When the lampshade 1 is rotated, the brightness of the light source assembly 101 increases, and when the lampshade 1 is rotated counterclockwise, the brightness of the light source assembly 101 decreases.

According to the specific connection relationship of the second control circuit, other functions of the lamp are realized. adjustment or parameter adjustment. At the same time, since the first control circuit is no longer connected to the rotary encoder 103, the light source assembly 101 does not change when the lampshade 1 is rotated.

Of course, the pressing state of the lampshade 1 may also include a third pressing state, a fourth pressing state, etc., for example, the pressing state of the lampshade 1 is further distinguished according to the floating height of the lampshade 1 relative to the base 2 or the duration of pressing the lampshade 1 . Correspondingly, the rotary encoder 103 in the third pressing state can be connected to the third control circuit of the controller, and the rotary encoder 103 in the fourth pressing state can be connected to the fourth control circuit of the controller. As for other adjustment methods of the lamp in the pressed state, reference may be made to the example settings of the first control circuit and the second control circuit, which will not be listed one by one here.

On the basis of the above embodiments, the lamp provided by the present invention further includes a sound source assembly 102 , and the second control circuit is connected to the sound source assembly 102 . When the lampshade 1 is in the second pressing state, the floating pressing component realizes the connection between the second control circuit and the rotary encoder 103 , so as to adjust the performance parameters of the sound source component 102 according to the signal obtained by the rotary encoder 103 . For example, when the lampshade 1 is rotated clockwise, the volume of the sound source assembly 102 increases, and when the lampshade 1 is rotated counterclockwise, the volume of the sound source assembly 102 decreases.

The performance parameters of the sound source component 102 include but are not limited to volume, and may also be parameters such as timbre and sound effects.

Further, the lamp provided by the present invention further includes a first circuit board 104 and a second circuit board 105 , the first control circuit is arranged on the first circuit board 104 , and the second control circuit is arranged on the second circuit board 105 .

When the lampshade is in the first pressing state, the floating pressing component realizes the circuit connection between the rotary encoder 103 and the first circuit board 104, and the motion signal of the lampshade 1 obtained by the rotary encoder 103 is transmitted to the first circuit board 104, and the first circuit board 104 Adjust the performance parameters of the light source assembly 101 according to the motion parameters of the lampshade 1 .

When the lampshade is in the second pressing state, the floating pressing component realizes the circuit connection between the second circuit board 105 and the rotary encoder 103, and the motion signal of the lampshade 1 obtained by the rotary encoder 103 is transmitted to the second circuit board 105, and the second circuit board 105 adjusts the performance parameters of the sound source assembly 102 according to the motion parameters of the lampshade 1 .

On the basis of the above embodiment, in order to simplify the operation, the lamp is further provided with a flexible encoder circuit board 106, the flexible encoder circuit board 106 is connected with the rotary encoder 103, and the signal obtained by the rotary encoder 103 is transmitted to the flexible encoder circuit board 106 . The middle part of the flexible encoder circuit board 106 is fixed to the base 2, the two ends are adjacent to the first circuit board 104 and the second circuit board 105 respectively, and the two ends of the floating pressing component alternately contact the first circuit board 104 and the second circuit board. 105, realize that the rotary encoder 103 is connected to the first control circuit or the second control circuit.

In addition to connecting the second control circuit to the sound source assembly 102, the second control circuit can also be set to open circuit. Under this setting, if the lampshade 1 is in the second pressing state, the rotary encoder 103 will not conduct after being connected to the second control circuit. Affects the on-off of the first control circuit of the light source assembly 101 . In short, the second control circuit in this embodiment can be regarded as a safety circuit against accidental touch, so as to prevent the user from accidentally touching the lampshade 1 and affecting the current use state of the lamp.

In addition, the second control circuit can also be connected to the disconnect switch of the light source assembly 101 , wherein the disconnect switch is arranged in the power circuit of the light source assembly 101 . The circuit breaker is a normally closed contact, that is to say, as long as the lampshade 1 is not in the second pressing state, the circuit breaker is not energized. At this time, the circuit breaker provided in the power circuit of the light source assembly 101 is in the closed state, so that the light source assembly 101 is in a closed state. power ups. Once the lampshade 1 is in the second pressing state, the disconnect switch is turned off after being powered on, so that the light source assembly 101 is powered off.

The lamp provided by the present invention uses the rotary encoder 103 to obtain the rotation angle of the lampshade 1, and the controller adjusts the performance parameters of the light source assembly 101 according to the aforementioned rotation angle in the first pressing state. Considering that the performance parameters of the light source assembly 101 are within a certain range, for example, in actual operation, the brightness of the light source assembly 101 can be adjusted from no light to a maximum brightness value. For better technical effect, if the aforementioned disconnect switch is regarded as the first disconnect switch, the first control circuit is connected with a second disconnect switch for disconnecting the power circuit of the light source assembly 101 when the brightness of the light source assembly 101 is adjusted to no light In other words, when the light source assembly 101 is adjusted to no light and when the lampshade 1 is in the second pressing state, the light source assembly 101 is disconnected from the power source. Of course, the first disconnect switch and the second disconnect switch may adopt the same structure.

The first pressing state of the lampshade 1 may refer to the state that the lampshade 1 is not pressed, and the second pressing state of the lampshade 1 specifically refers to the state of pressing and resetting the lampshade 1 . If the lampshade 1 further has a third pressing state and a fourth pressing state, it can be further distinguished according to the pressing duration of the lampshade 1 or the number of consecutive pressings of the lampshade 1 .

Of course, the second pressing state can also refer to the state of continuously pressing the lampshade 1. In other words, at this time, the first pressing state still refers to the state of not pressing the lampshade 1, and the second pressing state refers to pressing the lampshade 1 until the lampshade 1 is pressed. The rotation is completed. Correspondingly, if the lampshade 1 further has a third pressing state, a fourth pressing state, etc., it can be further distinguished according to the pressing amount of the lampshade 1 .

On the basis of any of the above embodiments, the base 2 provided by the present invention may include a housing 21 sleeved under the lampshade 1 and a support 22 fixed in the housing 21 .

Generally, the light source assembly 101 is fixed above the support 22 .

In this embodiment, the floating pressing assembly includes a guide post 31 vertically fixed to the lower end surface of the support 22 , an elastic body 32 sleeved on the guide post 31 , and a sliding connection to the guide post 31 and to the rotary encoder 103 . Floating part 33 .

The lamp provided in this embodiment is provided with a pressing space with a spacing of H1 between the lower end surface of the lampshade 1 and the top of the housing 21 . Taking FIG. 4 as an example, the lower end surface of the lampshade 1 is provided with a first floating surface 11 , and the top of the housing 21 A second floating surface 211 is provided. When the user does not press the lampshade 1 , the first floating surface 11 and the second floating surface 211 have a pressing space H1 under the support of the floating pressing component, so that the lampshade 1 can move downward.

The top end of the floating portion 33 is in contact with the lampshade 1 , and the bottom end is used for alternately electrically connecting the first control circuit and the second control circuit. For example, if the first control circuit is arranged below the floating part and above the second control circuit, when the lampshade 1 is pressed, the lampshade 1 drives the floating part 33 to move downward, and the bottom end of the floating part 33 is electrically connected to the first control circuit. When the lampshade 1 is released, the lampshade 1 drives the floating part 33 to move upward, and the bottom end of the floating part 33 is disconnected from the first control circuit and then connected to the second control circuit.

The middle portion of the floating portion 33 is fixed to the support 22 through the guide post 31 and the elastic body 32 sleeved thereon. The elastic body 32 can use a spring. When the floating part 33 is pressed by the lampshade 1, the middle part of the floating part 33 moves linearly downward along the guide column 31 and compresses the spring; after the lampshade 1 is released, the spring drives the middle part of the floating part 33 along the guide The column 31 moves upward in a straight line, and plays the role of resetting the floating part 33, which is equivalent to resetting the lampshade 1, which is convenient for the next operation.

Further, a micro switch 5 is provided between the floating part 33 and the first control circuit and the second control circuit, and two contacts of the micro switch 5 are respectively connected to the first control circuit and the second control circuit. The bottom end of the floating part 33 is pressed against the action reed 51 of the micro switch 5. When the lampshade 1 is pressed, the movement of the bottom end of the floating part 33 is transmitted to the micro switch 5, and the micro switch 5 sends the information to the first control circuit and the second control circuit. The second control circuit operates quickly. The micro switch 5 can convert the positional relationship when the floating part 33 moves up and down into precise and fast signals and continue to transmit them to the outside, thereby improving the response speed.

Further, the floating portion 33 includes a vertical end vertically downward and a horizontal end connected to the vertical end horizontally for pressing against the elastic body 32; at least two guide posts 31 are provided, and the vertical end of the floating portion 33 is installed In the center of all the guide posts 31 , in short, the edges of the floating portion 33 are jointly supported by a plurality of guide posts 31 and a plurality of elastic bodies 32 , so as to improve the stability of the floating portion 33 when floating.

Wherein, there are two guide columns 31, and accordingly, the floating portion 33 can be specifically configured as a T-shaped connecting rod. In this embodiment, by pressing the lampshade 1, the T-shaped link is moved downward to trigger the micro switch 5, and then the adjustment and switching of the first control circuit and the second control circuit are realized through the micro switch 5.

For the lamp provided by the present invention, the lower end surface of the lampshade 1 is fixedly connected with an external gear 61, and the interior of the external gear 61 is provided with an internal gear 62 for internal meshing. and the internal gear 62 to achieve rotation. Since the external gear 61 is fixed to the lampshade 1 , when the lampshade 1 is rotated, the external gear 61 rotates synchronously and drives the internal gear 62 to rotate.

The external gear 61 and the internal gear 62 are used as an external rotation mechanism between the lampshade 1 and the base 2. When the lampshade 1 is in the first pressing state, the lampshade 1 is rotated, and the rotation angle of the lampshade 1 is transmitted to the rotary encoder 103 by the external rotation mechanism. The first control circuit is turned on through the rotary encoder 103, so that the light source assembly 101 exhibits different brightness, and the user can realize the stepless adjustment of the brightness of the light source assembly 101.

The internal gear 62 is sleeved on the rotary encoder 103 . The purpose of this setting is, firstly, to simplify the connection between the rotary encoder 103 and the external gear 61, so as to facilitate the rotary encoder 103 to accurately and quickly obtain the rotation angle of the external gear 61 relative to the base 2, and secondly, to make the diameter smaller The rotation angle of the large outer gear 61 is enlarged to the rotation angle of the inner gear 62 with a smaller diameter, which improves the adjustment effect of the light source assembly 101 .

On the basis of this embodiment, the lamp can also be provided with a third floating surface and a fourth floating surface. The third floating surface is the lower end surface of the external gear 61 and the fourth floating surface is the upper end surface of the base 2. If the base 2 Consisting of the housing 21 and the support 22 , the fourth floating surface can be set as the upper end surface of the support 22 . There is a floating gap H2 between the third floating surface and the fourth floating surface, so that the lampshade 1 and the floating pressing assembly can move downward.

Of course, considering the first floating surface 11 and the second floating surface 211, if the gap between the first floating surface 11 and the second floating surface 211 is smaller than the gap between the third floating surface and the fourth floating surface, the floating distance of the lampshade 1 It is equal to the gap between the first floating surface 11 and the second floating surface 211 ; on the contrary, the floating spacing of the lampshade 1 is equal to the gap between the third floating surface and the fourth floating surface.

On the basis of the above-mentioned embodiment, the light source assembly 101 is fixed by the central fixing plate 7 arranged above the base 2; A snap-fitting end is convexly and concavely embedded to achieve a second snap-fitting end for rotational matching.

The end face of the first card-embedding end is attached to the end face of the second card-embedding end. When the lampshade 1 is rotated, the lampshade 1 drives the external gear 61 to rotate, and the second engaging end rotates around the rotation axis of the lampshade 1. Correspondingly, the first engaging end slides relatively within the second engaging end. Since the first engaging end and the second engaging end are in surface-to-surface contact, they are prevented from shaking due to gaps in the up and down and left and right directions in FIG. 5 at the same time. For example, when the first snap-in end and the second snap-in end are in contact with each other in the up-down direction, the smooth rotation of the lampshade 1 can be ensured by reasonably controlling the gap in the left-right direction; on the contrary, when the first snap-in end and the second snap-in end When the ends are in contact with the end faces in the left and right directions, the smooth rotation of the lampshade 1 can be ensured by reasonably controlling the gap in the up and down directions.

The end surfaces of the first engaging end and the second engaging end are abutted, and at least one of them is made of self-lubricating material, so as to reduce the frictional resistance between the first engaging end and the second engaging end.

The first engaging end can be configured as an annular groove, and the second engaging end can be configured as an annular boss. The rotation of the first engaging end relative to the second engaging end can be regarded as the coaxial rotation of the annular groove and the annular boss that are sleeved with each other.

Further, an adjusting screw 8 is connected between the external gear 61 and the central fixing plate 7 to adjust the interference between the first and second engaging ends. The adjusting screw 8 is inserted along the first engaging end and the second engaging end. The mating direction of the end extends.

The adjusting screw 8 is used to adjust the interference between the first and second clamping ends. On the contrary, reduce the amount of interference between the first engaging end and the second engaging end to expand the gap between the outer rotating mechanism and the central fixed plate 7 . Obviously, the smaller the gap between the outer rotating mechanism and the central fixed plate 7, the less obvious the shaking of the lampshade 1 relative to the central fixed plate 7 is.

In addition, the adjustment effect of the adjusting screw 8 on the interference of the first engaging end and the second engaging end is not only reflected in the gap between the outer rotating mechanism and the central fixing plate 7, but also reflected in the user's feel when rotating the lampshade 1 For example, the smaller the gap between the outer rotating mechanism and the central fixed plate 7, the greater the force required by the user to rotate the lampshade 1, and the larger the gap between the outer rotating mechanism and the central fixed plate 7, the more the user rotates the lampshade The force required at 1 is relatively reduced.

In addition, between the upper end of the external gear 61 and the lower end of the lampshade 1, there is also an outer rotating ring 9 fixedly connected with the second engaging end. The outer wall of the outer rotating ring 9 is fixedly connected with the inner wall of the lampshade 1, for example, the outer wall of the outer rotating ring 9 and the inner wall of the lampshade 1 are fixedly connected by snaps; end.

When the lampshade is rotated, the lampshade 1 drives the outer rotating ring 9 to rotate, and the outer rotating ring 9 further drives the external gear 61 to rotate. The performance parameters of the light source assembly 101 can be adjusted according to the angle change of the lampshade 1 obtained by the rotary encoder 103 .

In the present invention, the POM gear is used as the external gear 61 , and the POM rotating ring 10 is used as the second engaging end fixed to the central fixing plate 7 . The POM material has the effect of self-lubricating, which can reduce frictional resistance; the first clamping end of the POM gear is in surface-to-surface contact with the POM rotating ring 10, which can effectively solve the shaking problem of the lampshade 1 during the rotation.

The lamp provided by the present invention has been described in detail above. The principles and implementations of the present invention are described herein by using specific examples, and the descriptions of the above embodiments are only used to help understand the method and the core idea of the present invention. It should be pointed out that for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can also be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
