Abstract
The utility model relates to a LED warning lamp which comprises a circuit board and at least three LED lamp boars on the circuit board. The LED lamp board is provided with a LED lighting tube. Adjacent LED lamp boards remain certain gap. The utility model is beneficial in that: 1, the LED lamp boards are separated from each other so as to favor heat radiation of the lighting tubes; 2, through fixing frame for the lamp board, the lamp board is hold in the frame firmly and reliably.
Description
(1) technical field
The utility model relates to a kind of LED warning lamp.
(2) background technology
The LED warning lamp is made up of critical pieces such as base, lampshade, circuit board, lamp plates usually, Chinese patent CN2809419Y discloses a kind of small-sized polygon LED warning lamp, above being included in the warning lamp aluminium backing circuit board is housed, lampshade is buckled in outside the aluminium backing, and little magnet steel is housed on the aluminium backing bottom chassis; The center stand column of described circuit board is to form by joining to surrounding about 3 above LED lamp plates, at every LED lamp plate 2 above LED luminous tubes are installed up and down, every LED lamp plate all meets a shared LED pattern control centre with after separately drive circuit links to each other.Form because the lamp plate of this warning lamp joins to surrounding about being, thereby when warning lamp worked long hours, fluorescent tube can dispel the heat bad, breaks down easily.In addition, existing circuit board is connected by connector with lamp plate, and this bonding strength is not high, repeatedly rocks the disengagement of easy generation lamp plate.
(3) utility model content
Technical problem to be solved in the utility model is to provide a kind of LED warning lamp that dispels the heat good.
LED warning lamp of the present utility model comprises circuit board and three above LED lamp plates that are distributed on the circuit board, on the described LED lamp plate LED fluorescent tube is installed, described LED lamp plate space certain distance.
Further, described LED lamp plate evenly distributes around the circuit board center.
Further, described LED lamp plate number is four.
In order to improve the job stability of lamp plate, this warning lamp also is provided with polygon lamp plate fixed support, the support bracket fastened limit of described lamp plate number is identical with the number of LED lamp plate, support bracket fastened each sidepiece of described lamp plate longitudinally is provided with the draw-in groove that cooperates with described LED lamp plate respectively, and described lamp plate fixed support is fixedlyed connected with circuit board.
Above-mentioned lamp plate fixed support can adopt plastics or metal material (as aluminium) to make, and adopts metal material more to help the heat radiation of fluorescent tube on the lamp plate.
Further, the support bracket fastened bottom of described lamp plate is provided with screwed hole, and the lamp plate fixed support is connected by screw with circuit board.
The beneficial effects of the utility model are: 1, be spaced from each other between the LED lamp plate, help the fluorescent tube heat radiation; 2, by installing the lamp plate fixed support additional, lamp plate is stuck on the support, thereby lamp plate can reliablely and stablely be fixed.

(5) specific embodiment
The utility model is described in further detail below in conjunction with embodiment, but protection domain of the present utility model is not limited to this.
With reference to Fig. 1, Fig. 2, a kind of LED warning lamp comprises circuit board 1 and three above LED lamp plates 2 that are distributed on the circuit board, on the described LED lamp plate 2 LED fluorescent tube 3 is installed, described LED lamp plate 2 space certain distances.
Described LED lamp plate 2 evenly distributes around the circuit board center.
Described LED lamp plate 2 numbers are four.
With reference to Fig. 3, Fig. 4, Fig. 5, this warning lamp also is provided with polygon lamp plate fixed support 4, the limit number of described lamp plate fixed support 4 is identical with the number of LED lamp plate, support bracket fastened each sidepiece of described lamp plate longitudinally is provided with the draw-in groove 5 that cooperates with described LED lamp plate 2 respectively, and described lamp plate fixed support 4 is fixedlyed connected with circuit board 1.
The support bracket fastened bottom of described lamp plate is provided with screwed hole 6, and lamp plate fixed support and circuit board 1 are connected by screw.
During assembling, each lamp plate is penetrated in the support bracket fastened draw-in groove 5 of lamp plate, screw is screwed in the screwed hole 6 then, it is reliablely and stablely fixing that lamp plate is obtained.
