DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0049] See also Figure 1-Figure 8 , a multifunctional LED light source provided by an embodiment of the present invention includes an LED lamp holder 1, and further includes:

[0050] A supporting lamp panel 26, wherein the supporting lamp panel 26 is fixedly mounted in the LED lamp holder 1, and a plurality of fixing plates 27 are evenly distributed on the supporting lamp panel 26, and a telescopic lamp holder 28 is mounted on each of the fixing plates 27, and a plurality of lamp beads are fixedly mounted on the telescopic lamp holder 28;

[0051] and a heat dissipation control mechanism, the heat dissipation control mechanism is respectively connected to the LED lamp holder 1 and the telescopic lamp holder 28, wherein the heat dissipation control mechanism includes a drive control component, a heat dissipation adjustment component and a clutch control component;

[0052] The drive control component is connected to the LED lamp holder 1 , the heat dissipation adjustment component is connected to the LED lamp holder 1 and the drive control component respectively, the clutch control component is connected to the drive control component and is connected to the telescopic lamp holder 28 .

[0053] During the use of the LED light source, the brightness of the light source is often adjusted according to the use occasion to achieve the purpose of saving energy. During normal use, the telescopic lamp frame 28 is in an expanded state. At this time, the lamp beads distributed on the telescopic lamp frame 28 will evenly scatter light in the LED lamp holder 1 to ensure the lighting effect. In addition, the multiple lamp beads in a dispersed state are also conducive to improving the heat dissipation effect. However, when the LED light source generates a large amount of heat, first, start the drive control component, wherein the drive control component can be connected in series with the cable connecting the lamp beads. When the current in the cable increases, the drive control component will be put into operation accordingly. I will not go into details here. Under the driving effect of the drive control component, The heat dissipation adjustment component and the clutch control component are put into operation at the same time, wherein the heat dissipation adjustment component can change the size of the connecting port between the inside and outside of the LED lamp holder 1. The greater the current passed into the lamp bead, the larger the size of the connecting port between the inside and outside of the LED lamp holder 1 is, so as to ensure the heat dissipation effect. At the same time, the clutch control component can drive the telescopic lamp holder 28 to change from an expanded state to a retracted state, and the degree of retraction is positively correlated with the current passed into the lamp bead. During the retraction process of the telescopic lamp holder 28, multiple lamp beads can be gathered at the connecting port between the inside and outside of the LED lamp holder 1, so that the heat generated by the lamp beads can be quickly dissipated, which is beneficial to improve the heat dissipation rate and effect, and provides convenience for the staff.

[0057] An articulated seat 14, wherein the number of the articulated seats 14 is multiple, and the multiple articulated seats 14 are evenly distributed on the lifting column 13, and a connecting rod 15 is rotatably mounted on each of the articulated seats 14;

[0058] And a transmission unit, the transmission unit is connected to the LED lamp holder 1 and the connecting rod 15 respectively, and the transmission unit is also connected to the heat dissipation adjustment component and the clutch control component respectively.

[0059] The transmission unit comprises:

[0060] A support shaft 10, wherein the support shaft 10 is rotatably mounted on the LED lamp holder 1, and a driving bevel gear 6 is fixedly mounted on the support shaft 10;

[0065] And a mounting seat 9, wherein the mounting seat 9 is fixedly mounted on the top end of the telescopic control tube 8.

[0066] When the current flowing into the lamp bead increases, the current flowing into the electromagnetic drive block 12 increases synchronously. At this time, the magnetic force generated by the electromagnetic drive block 12 also increases. The number of the electromagnetic drive blocks 12 can be two. The two electromagnetic drive blocks 12 are respectively located on the telescopic control tube 8 and the lifting column 13, and are arranged opposite to each other. When the magnetic force of the electromagnetic drive block 12 increases, the magnetic repulsion between the two electromagnetic drive blocks 12 also increases, thereby pushing the lifting column 13 to move downward in the telescopic control tube 8. At this time, the reset spring 18 is in a compressed state, wherein the lifting column 13 and the telescopic control tube 8 are in a compressed state. The sliding mode of the inner wall of the control cylinder 8 adopts a structure in which a groove and a slide rail cooperate, so that the lifting column 13 can only move up and down. No further details are given here. When the lifting column 13 moves downward, the connecting rod 15 can be pushed to move downward synchronously. Under the thrust of the connecting rod 15, the transmission disc 17 can be driven to rotate via the eccentric shaft 16, wherein the eccentric shaft 16 and the transmission disc 17 are eccentrically arranged. When the transmission disc 17 rotates, the support shaft 10 can be driven to rotate on the LED lamp holder 1, and the driving bevel gear 6 can be driven to rotate synchronously, thereby driving the heat dissipation adjustment component and the clutch control component to operate.
