Abstract
The invention discloses an LED lamp strip comprising a PCB (Printed Circuit Board) and a plurality of LED lamps, wherein the plurality of LED lamps are uniformly arranged on the front face of the PCB at intervals. The LED lamp strip is characterized in that a heat radiating fin with a shape matched with that of the back of the PCB is arranged at the back of the PCB, and a plurality of branch heat radiating fins are uniformly arranged on the heat radiating fin at intervals. The LED lamp strip has good heat radiating performance and long service life.
Description
Technical field
The present invention relates to a kind of lamp bar, relate in particular to a kind of LED lamp bar.
Background technology
Many institutes Sundays, LED in use can produce bigger heat, and these heats are not if distributed the service life that will have a strong impact on LED timely.
Summary of the invention
It is better that technical problem to be solved by this invention provides a kind of heat radiation, the LED lamp bar that service life is long.
For solving the problems of the technologies described above; The present invention provides a kind of LED lamp bar; Comprise pcb board and a plurality of LED lamp; The evenly spaced front that is arranged on said pcb board of said a plurality of LED lamp, the back side of said pcb board are provided with the fin that adapts with the back side shape of said pcb board, also evenly spacedly on the said fin are provided with a plurality of heat radiations and prop up sheet.
Sheet is propped up in said heat radiation and said fin is one-body molded.
Compared with prior art, beneficial effect of the present invention is:
Because LED lamp bar of the present invention is provided with the fin that adapts with the back side shape of pcb board at the back side of pcb board; Use is that the heat that LED produces can distribute through fin timely; Also evenly spacedly on this external fin be provided with a plurality of heat radiations and prop up sheet, thereby effectively increased the area of dissipation of fin, so further strengthened radiating effect; Therefore thermal diffusivity of the present invention is better, and service life is longer.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is explained further details
Referring to shown in Figure 1; A kind of LED lamp bar; Comprise pcb board 1 and a plurality of LED lamps 2, a plurality of LED lamps 2 evenly spaced fronts that are arranged on pcb board 1, special feature of the present invention is: the back side of pcb board 1 is provided with the fin 3 that adapts with the back side shape of pcb board 1; The heat that this fin 3 can produce LED lamp 2 timely distributes; Also evenly spacedly on this external fin 3 be provided with a plurality of heat radiations and prop up sheet 4, this structural design has effectively increased the area of dissipation of fin, thereby has further strengthened radiating effect.
A preferred heat radiation sheet 4 is one-body molded with fin 3.
In sum, thermal diffusivity of the present invention is better, and service life is longer.
Claims (2)
1. LED lamp bar; Comprise pcb board and a plurality of LED lamp; The evenly spaced front that is arranged on said pcb board of said a plurality of LED lamp; It is characterized in that: the back side of said pcb board is provided with the fin that adapts with the back side shape of said pcb board, also evenly spacedly on the said fin is provided with a plurality of heat radiations and props up sheet.
2. LED bar according to claim 1 is characterized in that: sheet is propped up in said heat radiation and said fin is one-body molded.
