Description

Technical field:

[0001] The utility model belongs to the technical field of LED lamps, in particular to an RGB controllable LED lamp. Background technology:

[0002] RGB LED lights operate on the principle of three primary colors: red, green, and blue light mix to produce a variety of different colors. By precisely controlling the brightness of each color LED chip and the color mixing ratio, RGB LED lights can achieve rich color variations and delicate brightness adjustment.

[0003] High-power RGB LED lamps are often used for decorative lighting and demonstration stages in some large concerts, hotels, bars, building background lights and other places. As the use time of RGB LED lamps increases, RGB LED lamps are prone to heat and damage. RGB LED lamps in related technologies are mostly fixed to the installation position with screws. When a damaged RGB LED lamp needs to be repaired, it is necessary to unscrew the screws one by one after turning off the power, and then tighten the screws one by one after the repair is completed. The maintenance efficiency is low, and the installation structure of RGB LED needs to be improved. Summary of the invention:

[0004] The utility model provides an RGB controllable LED lamp to improve the maintenance efficiency of the RGB LED lamp.

[0005] The utility model is achieved in this way:

[0006] An RGB controllable LED lamp includes a connecting portion and a lamp body arranged on the connecting portion, wherein the connecting portion is fixed to an installation position by screws, and a slot is provided on the upper end surface of the connecting portion, the slot passing through a side of the connecting portion away from the installation position, and a snap-fit ​​portion is provided on the lamp body, and the snap-fit ​​portion is snapped into the slot.

[0007] Preferably, the connecting portion is provided with a pressure switch, which controls the on / off of the lamp body. The connecting portion is provided with a thermal expansion / contraction block, which expands and contracts when heated to depress the pressure switch. When the pressure switch is pressurized, the lamp body is de-energized; when the pressure switch is de-energized, the lamp body is energized. Preferably, the clamping portion is rotatably connected to the connecting portion, and the rotation axes of the clamping portion and the connecting portion are horizontal.

[0008] Preferably, the thermal expansion and contraction block is located between the lamp body and the connecting portion, and the thermal expansion and contraction block expands due to heat to cause the lamp body to rotate in a direction away from the connecting portion.

[0009] Preferably, a support rod is provided on the connecting portion, and the support rod is used to support the lamp body.

[0010] Preferably, the support rod is connected to the connecting portion in a lifting and sliding manner, and a positioning piece is provided on the support rod, and the support rod is fixed by the positioning piece.

[0011] Preferably, the positioning member is a positioning bolt, and the positioning bolt passes through the connecting portion and is threadedly connected to the support rod.

[0012] Preferably, the support rod is arranged at an angle, and the support rod is inclined away from the connecting portion in a direction close to the lamp body.

[0013] The outstanding advantages of the utility model compared with the prior art are:

[0014] 1. During the installation process of the RGB controllable LED lamp of the present invention, the installation of the lamp body can be completed by inserting the clamping part into the positioning groove. When the lamp body is damaged and needs to be repaired or replaced, the lamp body can be removed by moving the clamping part out of the positioning groove after the power is turned off. There is no need to remove the entire LED lamp, which is conducive to improving the efficiency of disassembly and assembly, and thus helps to improve the efficiency of maintenance;

[0015] 2. When the LED lamp of the present invention is used, as the use time increases, the surface temperature of the lamp body rises. As the temperature of the lamp body rises, the thermal expansion and contraction block expands due to the heat, abuts against the pressure switch, and the pressure is automatically cut off. After the power is cut off, the lamp body is left to cool down. As the temperature of the lamp body drops, the thermal expansion and contraction block contracts again and separates from the pressure switch, turning the LED lamp back on. This helps to reduce the risk of overheating and damage to the LED lamp, and helps to extend the service life of the LED lamp.

[0016] 3. The utility model places the thermal expansion and contraction block between the connecting part and the lamp body, which is beneficial to increase the contact between the thermal expansion and contraction block and the lamp body, and facilitates the timely response of the thermal expansion and contraction block.

[0025] See also Figure 1 and Figure 3 The end of the connecting portion 1 away from the installation position is provided with a plurality of sliding grooves 15. The distribution direction of the plurality of sliding grooves 15 is parallel to the rotation axis of the clamping portion 21, and the extension direction of the sliding grooves 15 is set vertically. The connecting portion 1 is connected to a plurality of support rods 16 for lifting and sliding connection. The position and number of the support rods 16 correspond one-to-one to the position and number of the sliding grooves 15. The support rods 16 are threaded with positioning members 161, and the support rods 16 and the connecting portion 1 are fixed by the positioning members 161. The support rods 16 are located below the lamp body 2. The ends of the support rods 16 away from the lamp body 2 are inserted into the corresponding sliding grooves 15. The support rods 16 are lifted and slidably connected to the connecting portion 1 along the corresponding sliding grooves 15.

When the lamp body 2 heats up, the heat is transferred to the thermal expansion and contraction block 4. The thermal expansion and contraction block 4 expands due to the heat and abuts against the pressure switch 3, applying pressure to the pressure switch 3, causing the pressure switch 3 to control the power off of the lamp body 2. At the same time, the thermal expansion and contraction block 4 presses against the lamp body 2, causing the lamp body 2 to rotate away from the connecting portion 1. This increases the contact area between the lamp body 2 and the air, improves the heat dissipation efficiency of the lamp body 2, and helps to extend the service life of the lamp body 2. The thermal expansion and contraction block 4 in this embodiment is a nickel-titanium alloy block. In other embodiments, the pressure switch 3 can be replaced by a push switch.

[0029] When the lamp body 2 is powered off, the staff can judge whether the lamp body 2 is powered off due to overheating by observing the angle between the connecting part 1 and the lamp body 2. If there is an angle between the lamp body 2 and the connecting part 1, it is powered off due to overheating. After waiting for the lamp body 2 to cool down, the thermal expansion and contraction block 4 will shrink and disengage from the pressure switch 3, and the lamp body 2 can be powered on again; if the lamp body 2 fits the connecting part 1, it is damaged inside the lamp body 2 and needs to be repaired.

[0030] The implementation principle of an RGB controllable LED lamp in an embodiment of the present application is: when the LED lamp needs to be repaired or replaced, the nut 141 is rotated to disengage the rotating rod 14, and then the rotating rod 14 is pulled out, and the lamp body 2 is lifted upward to disengage the clamping part 21 from the clamping slot 12, and the lamp body 2 can be removed without removing the entire LED lamp, which is beneficial to improving maintenance efficiency.
