For another example, the side wall hole is opened on the inner wall of the convection groove, that is, the side wall hole is communicated with the convection groove, so that part of the air flow in the contact process with the convection groove enters the ventilation groove through the side wall hole, and the heat-conducting fin has a better heat dissipation effect. For another example, the number of the side wall holes is plural, and the plural side wall holes are distributed at intervals along the extending direction of the convection slot. For another example, the distance between two adjacent side wall holes is 3 mm-5 mm, so that the air circulation effect between the air flow and the convection groove is better, and the heat dissipation effect of the heat conduction fins is better.

For example, when the plurality of LED lamp beads do not work, the controller controls the driving assembly to drive the cover plate to rotate forwards until the cover plate rotates to a first preset position relative to the lamp holder body, so that the cover plate blocks the corresponding area; when a plurality of LED lamp pearl during operation, controller control drive assembly drive the apron reversal, rotate to second preset position for the lamp stand body until the apron, make the apron leave first backup pad and second backup pad, convenient and fast. For example, the included angle between the plane at the first preset position and the plane at the second preset position is 90 degrees, so that the light penetrating through the lamp holder body is less shielded by the cover plate, and the cover plate has less influence on the light when the LED lamp beads work. If the lamp holder is used, the included angle between the plane where the first preset position is located and the plane where the second preset position is located is 180 degrees, the cover plate is provided with the light transmitting area, light which penetrates through the lamp holder body can penetrate through the cover plate, and therefore the influence of the cover plate on the light is small when the LED lamp beads work.
In one embodiment, each heat conducting plate mechanism is provided with a light transmitting area, so that light emitted by the LED lamp beads can sequentially penetrate through the lamp holder body and the heat conducting plate mechanism, and the heat conducting plate mechanism is prevented from shielding the light of the LED lamp beads. For example, each heat conducting plate mechanism comprises a driving assembly and a cover plate, wherein the driving assembly is arranged on the lamp holder body; the cover plate is connected to the output end of the driving assembly and is rotatably connected to the lamp holder body; the cover plate is provided with a light-transmitting area; the utility model discloses a LED lamp holder, including lamp stand body, drive assembly, lamp stand body, second backup pad, heat conduction plate mechanism, drive assembly and circuit board electricity, drive assembly drives the apron for the lamp stand body rotates, makes the apron is used for a plurality of the shutoff is corresponding when LED lamp pearl is out of work the region, and is used for a plurality of LED lamp pearl during operation leaves first backup pad with the second backup pad makes heat conduction plate mechanism the corresponding region of shutoff when a plurality of LED lamp pearls are out of work, and leaves first backup pad and second backup pad when a plurality of LED lamp pearls are in operation, makes the light that LED lamp pearl sent can see through lamp stand body and apron in proper order, avoids the apron to cause. For example, the cover plate is made of glass or PC (Polycarbonate), PMMA (polymethyl methacrylate), MABS (methyl methacrylate-acrylonitrile-butadiene-styrene plastic), PETG (ethylene terephthalate-1, 4-cylcohexylenedimethylene terephthalate, Polyethylene terephthalate-1, 4-cyclohexane dimethanol ester), AS (acrylonitrile-styrene copolymer), PS (Polystyrene ), NAS (acrylic copolymer), PVC (Polyvinyl chloride), PET (Polyethylene terephthalate), or the like.
As shown in fig. 1, for example, the LED lamp further includes a mounting assembly 600, one end of the mounting assembly is connected to a side of the socket body facing away from the heat conducting plate mechanism, and the other end of the mounting assembly is used to be fixed at a target position, such as a ceiling or a beam, so that the socket body is fixedly mounted at the target position. If the lamp holder body is welded with the mounting assembly, the mounting assembly is firmly connected with the lamp holder body. For example, the mounting assembly includes a fixing shaft and a mounting plate, one end of the fixing shaft is connected to the lamp holder body, the other end of the fixing shaft is connected to the mounting plate, the mounting plate is used for being fixed to a target position, one end of the mounting assembly is connected to one side of the lamp holder body, which is far away from the heat conducting plate mechanism, and the other end of the mounting assembly is used for being fixed to the target position. As another example, the mounting assembly further includes a fastener, a through hole is formed in the mounting plate, and the fastener is inserted into the through hole and connected to the target position, so that the mounting plate is detachably connected to the target position.
the LED lamp comprises a lamp holder, a circuit board, a plurality of LED lamp beads and a heat conducting plate mechanism, wherein the lamp holder comprises a lamp holder body, a first supporting plate and a second supporting plate, the lamp holder body is provided with a holding groove and a ventilation hole which are communicated, the circuit board is positioned in the holding groove, the circuit board is arranged on the lamp holder body, the plurality of LED lamp beads are all arranged on the circuit board, and each LED lamp bead is electrically connected with the circuit board; the first supporting plate and the second supporting plate are connected to the edge of the opening of the containing tank, the first supporting plate and the second supporting plate are arranged in a crossed mode and divide the opening of the containing tank into a plurality of areas, the plurality of heat conducting plate mechanisms are arranged on the lamp holder main body in a rotating mode, each heat conducting plate mechanism is arranged on the first supporting plate and the second supporting plate in a covering mode, each heat conducting plate mechanism is used for plugging the corresponding area when the plurality of LED lamp beads do not work, each heat conducting plate mechanism is used for leaving the first supporting plate and the second supporting plate when the plurality of LED lamp beads work, namely, each heat conducting plate mechanism rotates away from the first supporting plate and the second supporting plate when the plurality of LED lamp beads work, the heat conducting plate mechanisms are arranged on the first supporting plate and the second supporting plate in a covering mode when the plurality of LED lamp beads do not work, light rays emitted by the LED lamp beads can be better emitted through the containing tank, and, the heat dissipation efficiency of the lamp holder body is high, so that the heat dissipation performance of the LED lamp is good, and the service life of the LED lamp is long; because every heat-conducting plate mechanism is used for the corresponding region of shutoff when a plurality of LED lamp pearls are out of work, and leave first backup pad and second backup pad at a plurality of LED lamp pearls during operation, make LED lamps and lanterns when out of work heat-conducting plate mechanism cover locate first backup pad and second backup pad on, avoided sunshine direct irradiation to lead to oxidation with higher speed on the LED lamp pearl, and the difficult touching of foreign object to LED lamp pearl to make LED lamp pearl not fragile and normal operating time longer.
