Description

Technical Field

[0001] The utility model relates to the field of LED lamps, in particular to an LED lamp without backlight. Background Art

[0002] LED lights are widely used in various lighting applications due to their advantages of energy saving, environmental protection, and long life. However, traditional LED lights are often accompanied by backlight when emitting light, that is, the light radiates in all directions, which not only wastes light energy, but also may produce glare, affecting the user's visual experience.

[0003] Currently, structures such as sunshades or reflectors are often used to limit the divergence of light. Although these methods can reduce backlight to a certain extent, the effect is limited. In addition, since the installation angles of sunshades and reflector structures are fixed, they cannot be flexibly adjusted according to actual needs. As a result, the lighting range of LED lamps is relatively limited during use, and the flexibility during use is poor. Utility Model Content

[0006] By adopting the above-mentioned technical scheme, when it is necessary to adjust the angle of the sunshade, the driving motor can be started. After the driving motor is started, it will drive the screw sleeve to rotate. After the screw sleeve rotates, the screw rod will move up under the action of the threaded transmission. While moving up, the screw rod will use the connecting rod and the shift block to lift the corresponding sunshade, so as to increase the lighting range of the LED lamp body. Similarly, moving the connecting block downward can realize the lowering of the sunshade, so that the focusing lighting effect of the sunshade is better. Since the adjustment between each group of the sunshades is independent, in order to avoid the light transmittance between adjacent sunshades after adjustment, the gap at the edge of each sunshade is blocked with the help of sealing strips to ensure the convenient adjustment and use of the sunshade.

[0007] Furthermore, a control module is installed on an outer side wall of the LED lamp body, a wireless transceiver module is installed at a corner of the upper end of the LED lamp body, and two suspension rods are symmetrically installed on both sides of the upper end of the LED lamp body.

[0008] By adopting the above technical solution, the suspension rod is mainly used to achieve reliable installation and fixation of the LED lamp body on the indoor ceiling.

[0009] Furthermore, the control module is electrically connected to the LED lamp body, the wireless transceiver module and the drive motor.

[0010] By adopting the above technical solution, the control module mainly controls the convenient opening and closing of the LED lamp body and the driving motor by controlling the on-off of the circuit.

[0011] Furthermore, the light-blocking plate is hinged to the housing of the LED lamp body, the sealing strip is bonded to the light-blocking plate, and the sealing strip is made of a high light-shielding material.

[0012] By adopting the above technical solution, the light-shielding performance of the sealing strip can be effectively ensured.

[0013] Furthermore, the support is an inverted U-shaped structure, and the support is connected to the shell of the LED lamp body by bolts.

[0014] By adopting the above technical solution, the support can realize reliable installation and fixation of the driving motor on the upper side of the LED lamp body shell.

[0015] Furthermore, the driving motor is connected to the support bolts, and the nut is connected to a power output shaft coupling of the driving motor.

[0016] By adopting the above technical solution, the driving motor mainly provides power for the rotation of the screw sleeve.

[0017] Furthermore, the screw sleeve is rotatably connected to the support, the screw sleeve is threadedly connected to the screw rod, and the screw rod is welded to the connecting block.

[0018] By adopting the above technical solution, it can be ensured that the connecting block rises and falls synchronously with the screw rod.

[0019] Furthermore, the connecting block is hinged to the connecting rod, the connecting rod is hinged to the shifting block, and the shifting block is slidably connected to the shifting groove.

[0020] By adopting the above technical solution, the light baffle can be conveniently rotated and adjusted relative to the LED lamp body housing under the action of the connecting rod to ensure that the LED lamp body has no backlight when in use.

[0021] Compared with the prior art, the utility model has the following beneficial effects:

A flexible sealing strip 7 is also installed at the bottom edge of each light blocking plate 5. Since the adjustment between each group of light blocking plates is independent, in order to avoid light transmission between adjacent light blocking plates after adjustment, the sealing strip 7 is used to block the gap at the edge of each light blocking plate to ensure the convenient adjustment and use of the light blocking plate.

[0033] Among them, when it is necessary to adjust the angle of the shading plate, the driving motor 607 can be started. After the driving motor 607 is started, it will drive the screw sleeve 606 to rotate. After the screw sleeve 606 rotates, the screw rod 605 will move up under the action of the threaded transmission. While moving up, the screw rod 605 will use the connecting rod 602 and the shift block 603 to realize the corresponding lifting of the shading plate, so as to increase the lighting range of the LED lamp body 3. Similarly, moving the connecting block 601 downward can realize the lowering of the shading plate, so that the focusing lighting effect of the shading plate is better.

[0038] The specific implementation process of this embodiment is as follows: when in use, first install the LED lamp body 3 on the indoor ceiling with the help of the suspension rod 1, and connect the LED lamp as a whole to the indoor power supply, and then the LED lamp can be put into use. During use, when the wireless transceiver module 2 receives the start-up command, it will start the LED lamp body 3 through the control module 4 to illuminate. When it is necessary to adjust the angle of the shading plate as needed during the lighting process, the drive motor 607 is started. After the drive motor 607 is started, it will drive the screw sleeve 606 to rotate. After the screw sleeve 606 rotates, The screw 605 will move upward under the action of the threaded transmission. While moving upward, the screw 605 will use the connecting rod 602 and the shift block 603 to lift the corresponding shading plate, so as to increase the lighting range of the LED lamp body 3. Similarly, moving the connecting block 601 downward can realize the downward adjustment of the shading plate, so that the focusing lighting effect of the shading plate is better.
