Abstract

The utility model discloses an ultrathin LED (light-emitting diode) lightbar. The lightbar comprises a light body (1), two metal heat-dissipating plates (4), end covers (5) connected with the metal heat-dissipating plates (4), lamp groups I (2) arranged on the front side and the rear side of the light body (1), lamp groups II (6) positioned at the two edges of the lamp body (4) and supporting legs (3) connected at the bottom part of the lamp body (1); the bottom surfaces of the metal heat-dissipating plates (4) are similar to isosceles trapezoids; the short edges and the two side edges of the metal heat-dissipating plates (4) are connected with connecting plates I (7) used for connecting the lamp groups II (6); the long edges of the metal heat-dissipating plates (4) are connected with connecting plates II (8) used for connecting the metal heat-dissipating plates (4) with the two edges of the lamp body (1); and the connecting plates I (7) and the connecting plates II (8) are all vertical to the bottom surfaces of the metal heat-dissipating plates (4). The ultrathin LED lightbar has the advantages of better heat dissipating effect and simpler structure.

Description

The ultra-thin long row police lamp of LED

Technical field

The utility model relates to the ultra-thin long row police lamp of a kind of LED.

Background technology

At present, the prior art long row police lamp generally comprises alarming lamp body, is located at the some lamp groups on alarming lamp body front and the back and is connected the alarming lamp body bottom surface and is used for the feet that is connected with vehicle; The right and left of described alarming lamp body respectively is connected with a lamp group seat; Be connected with end cap and some lamp groups on the described lamp group seat; The bottom of described lamp group seat is connected with metallic heat radiating plate.Though the long row police lamp of said structure has the effect of 360 ° of comprehensive cautions, but still there is a weak point in it: since between metallic heat radiating plate and the lamp group every a lamp group seat, and being nonmetallic materials usually, makes lamp group seat, therefore, the caloric requirement that is connected the lamp group release on alarming lamp body the right and left lamp group seat just can be delivered on the metallic heat radiating plate by lamp group seat, thereby causes having reduced to a certain extent the radiating effect of long row police lamp.

The utility model content

The technical problems to be solved in the utility model is, provides that a kind of radiating effect is better, the structure ultra-thin long row police lamp of simple LED more.

For solving the problems of the technologies described above, the utility model provides a kind of ultra-thin long row police lamp of LED that adopts following structure: it comprises alarming lamp body, two metallic heat radiating plates, end caps, be located at lamp group I on alarming lamp body front and the back, be positioned at the lamp group II on alarming lamp body both sides and be connected the feet of alarming lamp body bottom; The bottom surface of described metallic heat radiating plate is isosceles trapezoid; All be connected with the connecting plate I that is used for being connected lamp group II on the minor face of described metallic heat radiating plate and two sides; Be connected with the connecting plate II that metallic heat radiating plate can be connected on the alarming lamp body both sides on the long limit of described metallic heat radiating plate; Described connecting plate I is all vertical with the bottom surface of metallic heat radiating plate with connecting plate II; The bottom surface of described metallic heat radiating plate is provided with the joint pin that is used for connecting end cap and is threaded through hole.

After adopting said structure, the utlity model has following advantage: be directly installed on the metallic heat radiating plate because the utility model will be positioned at the lamp group on alarming lamp body both sides under the situation of saving lamp group seat, therefore, the heat that the lamp group discharges just can be directly delivered on the heat sink, thereby has strengthened the radiating effect of the ultra-thin long row police lamp of LED; In addition, the omission of lamp group seat also makes structure of the present utility model become simpler.

The specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

As Fig. 1, Fig. 2 and shown in Figure 3, in this specific embodiment, the ultra-thin long row police lamp of the utility model LED comprises alarming lamp body 1, two metallic heat radiating plates 4, end caps 5, be located at lamp group I 2 on alarming lamp body 1 front and the back, be positioned at the lamp group II 6 on alarming lamp body 1 both sides and be connected the feet 3 of alarming lamp body 1 bottom; The bottom surface of described metallic heat radiating plate 4 is isosceles trapezoid; All be connected with the connecting plate I 7 that is used for being connected lamp group II 6 on the minor face of described metallic heat radiating plate 4 and two sides; Be connected with the connecting plate II 8 that metallic heat radiating plate 4 can be connected on alarming lamp body 1 both sides on the long limit of described metallic heat radiating plate 4; Described connecting plate I 7 is all vertical with the bottom surface of metallic heat radiating plate 4 with connecting plate II 8; Described end cap 5 is divided into upper end cover and bottom end cover; The shape of described upper end cover and bottom end cover is in full accord, and all is to be connected on the described metallic heat radiating plate 4, and it is to use same template to produce upper end cover and bottom end cover that the shape of upper end cover and bottom end cover is made consistent purpose, thereby reduces production cost; Described metallic heat radiating plate 4, connecting plate I 7 and connecting plate II 8 are an integral body.
