The top end of the floating part 33 is contacted with the lampshade 1, and the bottom end is used for being alternately and electrically connected with the first control circuit and the second control circuit. For example, the first control circuit is disposed below the floating portion, and the second control circuit is disposed above the floating portion, so that when the lamp shade 1 is pressed, the lamp shade 1 drives the floating portion 33 to move downward, the bottom end of the floating portion 33 is electrically connected to the first control circuit, when the lamp shade 1 is released, the lamp shade 1 drives the floating portion 33 to move upward, and the bottom end of the floating portion 33 is disconnected from the first control circuit and then is connected to the second control circuit.

The elastic body 32 can be a spring, when the floating part 33 is pressed by the lampshade 1, the middle part of the floating part 33 makes a straight line movement downwards along the guide post 31 and compresses the spring; after the lampshade 1 is loosened, the spring drives the middle part of the floating part 33 to move linearly upwards along the guide post 31, so that the floating part 33 is reset, the lampshade 1 is reset, and the next operation is facilitated.

Further, a micro switch 5 is provided between the floating portion 33 and the first control circuit and the second control circuit, and two contacts of the micro switch 5 are connected to the first control circuit and the second control circuit, respectively.

Here, the guide posts 31 are provided in two, and accordingly, the floating portion 33 may be specifically provided as a T-shaped link. This embodiment drives T type connecting rod downstream in order to trigger micro-gap switch 5 through pressing lamp shade 1, and then realizes the regulation switching to first control circuit and second control circuit through micro-gap switch 5.

To the utility model provides a lamp, the lower terminal surface fixedly connected with external gear 61 of its lamp shade 1, the inside of external gear 61 is provided with the internal gear 62 that is used for realizing the internal gearing, that is to say, lamp shade 1 realizes rotatoryly through the external gear 61 and the internal gear 62 of internal gearing. Since the external gear 61 is fixed to the lamp housing 1, when the lamp housing 1 is rotated, the external gear 61 rotates synchronously and rotates the internal gear 62.

The outer gear 61 and the inner gear 62 are used as an outer rotating mechanism between the lamp shade 1 and the base 2, when the lamp shade 1 is in the first pressing state, the lamp shade 1 is rotated, the outer rotating mechanism transmits the rotation angle of the lamp shade 1 to the rotary encoder 103, and the rotary encoder 103 is connected with the first control circuit, so that the light source assembly 101 presents different brightness, and the brightness of the light source assembly 101 can be adjusted steplessly by a user.

Wherein, the inner gear 62 is sleeved on the rotary encoder 103. This arrangement is intended to simplify the connection between the rotary encoder 103 and the outer gear 61, facilitate the rotary encoder 103 to accurately and rapidly acquire the rotation angle of the outer gear 61 relative to the base 2, and enlarge the rotation angle of the outer gear 61 having a larger diameter to the rotation angle of the inner gear 62 having a smaller diameter, thereby improving the adjustment effect of the light source assembly 101.

On the basis of this embodiment, the lamp may further be provided with a third floating surface that is the lower end surface of the external gear 61 and a fourth floating surface that is the upper end surface of the base 2, and if the base 2 is formed by the housing 21 and the support 22, the fourth floating surface may be provided as the upper end surface of the support 22. The third floating surface and the fourth floating surface are provided with a floating gap H2 between them, which can allow the lampshade 1 and the floating pressing component to move downwards.

Of course, when viewed in conjunction with 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 is equal to the gap between the first floating surface 11 and the second floating surface 211; conversely, the floating distance 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 embodiment, the light source assembly 101 is fixed by the central fixing disc 7 disposed above the base 2; the lower end face of the central fixed disk 7 is provided with a first clamping and embedding end, and the upper end face of the outer gear 61 is provided with a second clamping and embedding end which is convexly and concavely embedded with the first clamping and embedding end to realize rotating fit.

The end face of the first clamping end is attached to the end face of the second clamping end. When the lampshade 1 is rotated, the lampshade 1 drives the outer gear 61 to rotate, at the moment, the second clamping and embedding end rotates around the rotating shaft of the lampshade 1, and correspondingly, the first clamping and embedding end slides relatively in the second clamping and embedding end. Because the first clamping and embedding end is in surface contact with the second clamping and embedding end, the first clamping and embedding end and the second clamping and embedding end are prevented from shaking due to gaps in the vertical direction and the left direction and the right direction of the figure 5. For example, when the first and second engaging ends are engaged with each other at the end surfaces in the up-down direction, the lampshade 1 can be ensured to rotate smoothly by reasonably controlling the gap in the left-right direction; on the contrary, when the first clamping and embedding end and the second clamping and embedding end are attached to the end faces in the left and right directions, the lampshade 1 can be ensured to rotate smoothly by reasonably controlling the gap in the up and down directions.

The first clamping and embedding end face is attached to the second clamping and embedding end face, and at least one of the first clamping and embedding end face and the second clamping and embedding end face is made of a self-lubricating material so as to reduce friction resistance between the first clamping and embedding end and the second clamping and embedding end.

The first clamping and embedding end can be arranged as an annular groove, and the second clamping and embedding end can be arranged as an annular boss. The rotation of the first clamping end relative to the second clamping end can be regarded as the coaxial rotation of the annular groove and the annular boss which are mutually sleeved.

Further, an adjusting screw 8 for adjusting the interference between the first engaging end and the second engaging end is connected between the external gear 61 and the central fixed disk 7, and the adjusting screw 8 extends along the engaging direction of the first engaging end and the second engaging end.

The adjusting screw 8 is used for adjusting the interference of the first engaging end and the second engaging end, for example, the interference of the first engaging end and the second engaging end is increased to reduce the gap between the outer rotating mechanism and the central fixing plate 7, and conversely, the interference of the first engaging end and the second engaging end is reduced to enlarge the gap between the outer rotating mechanism and the central fixing plate 7. Obviously, the smaller the gap between the outer rotating mechanism and the central fixed disk 7, the less pronounced the wobbling of the globe 1 relative to the central fixed disk 7.

In addition, the adjusting screw 8 not only acts on the gap between the outer rotating mechanism and the central fixing plate 7 to adjust the interference between the first engaging end and the second engaging end, but also acts on the hand feeling of the user when rotating the lampshade 1, for example, the smaller the gap between the outer rotating mechanism and the central fixing plate 7 is, the larger the force is required when the lampshade 1 is rotated by the user, and the larger the gap between the outer rotating mechanism and the central fixing plate 7 is, the smaller the force is required when the lampshade 1 is rotated by the user.

An outer rotating ring 9 fixedly connected to the second engaging portion is provided between the upper end of the outer gear 61 and the lower end of the lamp housing 1. 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 is fixedly connected with the inner wall of the lampshade 1 through a buckle; the inner wall of the outer rotating ring 9 is sleeved with a first clamping end and a second clamping end.

When the lampshade rotates, the lampshade 1 drives the outer rotating ring 9 to rotate, the outer rotating ring 9 further drives the outer gear 61 to rotate, the outer gear 61 and the inner gear 62 are meshed to rotate, the angle change of the inner gear 62 is transmitted to the rotary encoder 103, and therefore the performance parameters of the light source assembly 101 are adjusted according to the angle change of the lampshade 1 obtained by the rotary encoder 103.

The utility model discloses a POM gear adopts POM to rotate circle 10 as the second inlay card end that is fixed in central fixed disk 7 as outer gear 61. The POM material has a self-lubricating effect, and can reduce friction resistance; the first inlay card end and the POM of POM gear rotate 10 face-to-face contacts of circle, can effectively solve the problem of rocking of lamp shade 1 in the rotation process.

The above is to the lamp provided by the utility model is introduced in detail.
