For achieving the above object, the utility model proposes a kind of screw type LED thermal louver, comprise lamp screw base, shell body, radiating cylinder body, LED lamp bead cylinder, Transparent lamp shade, described lamp screw base is connected with shell body by screw connection, and shell body top and Transparent lamp shade are connected and install; Be provided with radiating cylinder body in described shell body, be provided with ventilation cover plate bottom radiating cylinder body, radiating cylinder body inside is provided with radiating piece; Be provided with LED lamp bead cylinder outside described radiating piece, LED lamp bead wound packages is fitted on radiating cylinder body inside, and LED lamp bead cylinder is arranged on ventilation cover plate upper surface; Described LED lamp bead cylinder surface is bonded with some LED lamp bead.
As preferably, described radiating piece is column structure, and radiating piece surface is circumferentially uniformly distributed some heat radiation spokes.
As preferably, LED lamp bead jacket casing is connected on radiating piece outside, and LED lamp bead is uniformly distributed in LED lamp bead cylinder upper surface and side surface circumference.
As preferably, be provided with driving power in described shell body, driving power is electrically connected to lamp screw base, and driving power is electrically connected with LED lamp bead cylinder.
As preferably, described ventilation cover plate has passage, passage is uniformly distributed in ventilation cover plate upper annular.
As preferably, described lamp screw base adopts E40 screw socket.
The beneficial effects of the utility model: the utility model passes through the LED lamp bead of LED lamp bead cylinder upper surface and side, lighting angle is large, and illumination effect is good, by radiating cylinder body and radiating piece heat radiation, structural strength is good, and area of dissipation is large, can meet the heat radiation needs of LED lamp bead; Passage on ventilation cover plate carries out auxiliary heat dissipation, good heat dissipation effect, and structure is simple, and security performance is good.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
