Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-2, an illumination device comprising: the LED lamp comprises a shell, a base, one or more LEDs, a PCB and a main circuit; the base is arranged below the shell and connected with the shell, the connection mode of the base and the shell can adopt the connection modes of buckle connection, threaded connection, spline connection and the like, and the connection modes are common connection modes, so the details are not described herein;

the lighting device is connected with the main circuit; a main circuit (not shown) is arranged on the PCB; the power supply is connected with the main circuit and is used for supplying power to the main circuit when the main circuit is switched on, the main circuit is used for driving the lighting device, the lighting device is lightened when the main circuit is switched on, and the lighting device is extinguished when the main circuit is switched off; the connection between the lighting device and the main circuit and the connection between the power supply and the main circuit may be direct connection or indirect connection, which are commonly used in the art, and therefore, the detailed description thereof is omitted here.

As shown in fig. 3, the base is provided with a first protrusion and a second protrusion; the PCB is connected with the base through the first bulge and the second bulge; the connection mode of the PCB and the first and second protrusions may adopt a snap connection, a thread connection, a spline connection, and the like, and is preferably a screw connection.

As shown in fig. 4, the lighting device further includes a weight block; the balancing weight is arranged between the base and the PCB; the balancing weight is used for increasing the total weight of the lighting device to stabilize the gravity center of the lighting device, and especially has a better effect when the size of the lighting device is larger, as shown in the following figure, along with the increase of the weight-volume ratio, the texture of the lighting device is in direct proportion to the cost of the balancing weight, namely the texture is better, the cost of the balancing weight is higher, and the weight-volume ratio is smaller than 2g/cm³The weight and volume ratio of the lighting device is preferably increased to not less than 2g/cm from the viewpoint of texture, but the weight and volume ratio of the weight and volume ratio is preferably increased to be lower than 2g/cm³。

In some embodiments, assume that the lighting device without the counterweight has a weight of 50g and a volume of 100cm³In this case, the weight of the weight block should be not less than 150g, so that the weight-to-volume ratio of the lighting device equipped with the weight block is increased by 2g/cm³(ii) a Certainly, the weight of the weight block is not limited to 150g, and it may be 100g or 200g, and when it is 150g, the obtained effect is better, and the cost is lower, and when the weight volume ratio is larger, the center of gravity of the lighting device is more stable, and the hand-held texture is better.

As shown in fig. 4, in some embodiments, the weight includes a first end and a second end; a first notch is formed in the part, close to the first bulge, of the first end; a second notch is formed in the part, close to the second bulge, of the second end; the weight block is movable between the base and the PCB; the moving track of the balancing weight is limited by the first bulge and the second bulge, namely the balancing weight can only move towards the first bulge and the second bulge but can not move towards other directions so as to ensure that the moving position of the balancing weight is controllable; of course, the number of the protrusions of the base is not limited to 2, and may be plural.

As shown in fig. 4, in some embodiments, the movement track of the weight member may not be limited by the first end and the second end, for example, a third protrusion is disposed in the weight member, a hole is disposed in the PCB, and the third protrusion passes through the hole and is movable. Thus, in this configuration, the weight member can move along a predetermined trajectory without the first end and the second end.

In some embodiments, a side of the PCB near the base or the first protrusion or the second protrusion is provided with a first switch (not shown in the figures); the first switch may be triggered when the weight block moves toward and approaches the PCB; when the lighting device is placed in a working mode (for example, the base is under), the counterweight block is at the first position, the first switch cannot be triggered by the counterweight block, when the lighting device is inverted or placed in other modes, the counterweight block is displaced and moves to the second position under the action of inertia and gravity, the first switch is triggered by the counterweight block, and the first switch can be a micro switch, a pressure sensor and the like; a microswitch is preferred here.

In some embodiments, the first switch is connected to an alert member, and the alert member is turned on when the first switch is triggered. The prompting component can prompt the user in a sound or optical mode, and remind the user in a sound mode of adopting a buzzer, playing music and the like, and preferably, the prompting component is a buzzer; the user is alerted optically by the flashing or extinguishing of the lights.

In some embodiments, a support portion is further disposed on the base; the supporting part is used for supporting the balancing weight; a second switch (not shown in the figure) is arranged on the supporting part; the second switch is triggered when the support portion supports the weight block. When the lighting device is in a normal placing state, the base is arranged on the lower lampshade, the balancing weight is tightly attached to the supporting part under the action of gravity and is in a first position, and the second switch arranged on the supporting part is in a triggered state; when the lighting device is changed from the normal placement state to the abnormal placement state (such as turning over or upside down), the counterweight block will be displaced under the action of inertia and gravity, and move from the first position to the second position.

In some embodiments, the second switch (not shown in the drawings) is connected to the main circuit, the main circuit is turned on when the second switch is triggered, that is, the main circuit is turned on when the counterweight block is in the first position, at which time the user can control the lighting device to be turned on and off through the operating button or APP, and the main circuit is turned off when the counterweight block moves from the first position to the second position, at which time the lighting device cannot be turned on no matter how the user operates the operating button or APP. As for the wireless control of the lighting device by the APP is prior art in the field, it is not described herein.

In some embodiments, the support comprises a first support and a second support; the second support portion is disposed within the first support portion. The second supporting part will first supporting part internal partitioning is two cavitys, and the second supporting part can improve the intensity of first supporting part as the stiffening rib of first supporting part this moment, and first supporting part and second supporting part are injection moulding as an organic whole simultaneously, can avoid first supporting part to warp at injection moulding's in-process through the aforesaid setting, reduce the defective rate in the product production process.
