DETAILED DESCRIPTION

[0022] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0025] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0026] like Figure 1-6 The brightness-adjustable LED floodlight shown includes a lamp housing 1 that is roughly in the shape of a rectangular parallelepiped. The front of the lamp housing 1 is rectangular. A light-emitting panel 110 is disposed on the front of the lamp housing 1. The light-emitting panel 110 occupies most of the area on the front of the light-emitting panel 110. The light-emitting panel 110 is usually also a regular image, and its geometric center coincides with the geometric center of the front of the lamp housing 1.

[0027] A mode knob 5 is provided at the upper right corner of the lamp housing 1, and the light-emitting mode of the light-emitting panel 110 can be changed by rotating it. A right rotation groove 103 is provided between the top surface and the right side surface of the lamp housing 1, and the mode knob 5 is located in the right rotation groove 103, but most of the outer side surface of the mode knob 5 is located outside the right rotation groove 103 and protrudes from the outer surface of the lamp housing 1. Since the mode conversion must be separated particularly clearly, the lamp housing 1 is provided with a graded rotating shaft 107 in the right rotation groove 103. Both ends of the graded rotating shaft 107 are inserted into the lamp housing 1 and squeezed by the spring sheet in the lamp housing 1. It can rotate but can only stay at a specific angle. Any angle between the specific angles is unstable. This structure belongs to a very mature existing technology and is not shown here. The function realized is that every time the graded rotating shaft 107 rotates to a certain angle, the contact of the corresponding angle is connected through the controller in the lamp housing 1 to allow the light-emitting panel 110 to maintain a light-emitting mode. The light-emitting modes include but are not limited to: always on, flashing, color changing, red and blue flashing, etc., and the available modes can be combined according to actual needs. The mode knob 5 is provided with a second axial hole 601 that passes through the two end faces, which is suitable for plugging with the graded rotating shaft 107. The two can achieve synchronous rotation through the key structure. The outer side of the mode knob 5 is provided with a friction groove 502, which is used to increase the friction force of the finger turning the mode knob 5.

[0028] A brightness knob 6 is provided at the upper left corner of the lamp housing 1, and the power supply of the light-emitting panel 110 can be changed by rotating it, thereby changing the brightness of the floodlight. A left rotation groove 104 is provided between the top surface and the left side surface of the lamp housing 1, and most of the brightness knob 6 is located in the left rotation groove 104, but the side of the brightness knob 6 is exposed outside the left rotation groove 104. The lamp housing 1 is provided with a stepless rotating shaft 108 in the left rotation groove 104. After the two ends of the stepless rotating shaft 108 are matched with the lamp housing 1, they can stay at any continuous angle. Because the adjustment of physical quantities such as resistance, voltage, current and power can be continuous, a resistance adjustment mechanism electrically connected to the light-emitting panel 110 is provided at any end of the stepless rotating shaft 108 to achieve For stepless adjustment, the brightness knob 6 is provided with a first axial hole 501 that passes through both end faces, which is also used for being inserted into the stepless rotating shaft 108 and keeping synchronous rotation with the stepless rotating shaft 108. The lamp housing 1 is also fixedly connected with a limit rod 109 in the left rotation groove 104. The axis of the limit rod 109 is parallel to the axis of the stepless rotating shaft 108. A limit slide groove 602 is provided on the end face of the brightness knob 6, which just cooperates with the limit rod 109 to form a sliding pair, which is used to limit the rotatable angle range of the brightness knob 6 and avoid the resistance adjustment mechanism at the end of the stepless rotating shaft 108 from being broken due to exceeding the adjustment stroke. In fact, a friction groove 502 is also provided on the outer side of the brightness knob 6, which is also used to increase the friction force of the finger when turning the brightness knob 6 and reduce slipping.

[0029] A master control switch 3 and a display screen 4 are also provided on the front of the lamp housing 1. In the present embodiment, the master control switch 3 is located at the lower right corner of the front of the lamp housing 1, and is used to control the on and off of the light-emitting panel 110. The display screen 4 is located at the lower left corner of the front of the lamp housing 1, and is mainly used to display the remaining power of the translucent lamp. Of course, the time and the charging status can also be displayed. The working mode of the floodlight can also be displayed on the display screen 4. A plus and minus identifier 106 is provided at the upper left corner of the front of the lamp housing 1, and is located at the end of the brightness knob 6, and is used to prompt the user which direction to rotate to increase the brightness and which direction to rotate to reduce the brightness. A mode identifier 105 is provided at the upper right corner of the front of the lamp housing 1. The mode identifier 105 includes a plurality of mode symbols. The function of the symbol is to prompt the user in which direction to turn the mode knob 5 faster if he wants to enter a certain mode. Only a clicking sound will be heard when the mode knob 5 is turned forward and reversely, and it can be rotated infinitely in the same direction without being limited like the brightness knob 6.

[0030] The left and right sides of the lamp housing 1 are provided with clearance grooves 101, and the ends of the bracket of the floodlight can be embedded in the clearance grooves 101. The lamp housing 1 is fixedly connected with a first bracket shaft 102 in each clearance groove 101, which is used to be plugged with the bracket structure to form a rotating pair. The back of the lamp housing 1 is fixedly connected with a battery compartment 2, which serves as a mobile power source for the floodlight. Therefore, the floodlight can be used normally without being plugged in. The left and right sides of the battery compartment 2 are respectively fixedly connected with a second bracket shaft 202, which can also be coordinated with the bracket of the floodlight, and can also be connected with a hanging rope as a structure for expanding the connection of the entire floodlight. The bottom surface of the battery compartment 2 is also provided with a heat dissipation grid 201 to increase the surface area of ​​the floodlight and improve the heat dissipation efficiency.

[0031] Working principle: When in use, the floodlight is set up in a suitable position using a bracket. After pressing the main control switch 3, the controller inside the lamp housing 1 is energized, and the light-emitting panel 110 is powered through the contacts at the end of the graded shaft 107 and the resistance adjustment mechanism at the end of the stepless shaft 108. The light-emitting power is adjusted by turning the brightness knob 6, and the light-emitting mode is adjusted by rotating the mode knob 5. The remaining power of the power supply in the battery compartment 2 can be observed on the display screen 4. The power supply in the battery compartment 2 is generally rechargeable, and dry batteries can also be used directly.
