Embodiment 1:

Refer to FIG. 1 and FIG.3. Embodiment 1 discloses a novel LED line light, consisting of a frame which is formed by connecting four rims end by end, wherein the four rims are fixedly connected end by end in sequence; each one of the rims is internally equipped with an LED light bar 1; the frame is integrally provided with four LED light bars, so the whole novel LED line light has sufficient light rays and achieves a better light effect than a single LED light bar has.
Each one of the rims has a first flat plate 2; each one of the first flat plates is respectively vertically fixed with a first vertical plate 3 and a second vertical plate 4 along two edges; the top of each one of the first vertical plates is fixed with one edge of each corresponding one of the first flat plates; the top of each one of the second vertical plates is fixed with the other edge of each corresponding one of the first flat plates; the first flat plates, the first vertical plates and the second vertical plates form a downward frame opening, and every two adjacent rims are fixed by mutually welding the first flat plates thereof.
The bottom inner wall of each one of the first vertical plates has a protruding first convex strip; each one of the first convex strips is formed by protrusion or bending of the bottom inner wall surface of each corresponding one of the first vertical plates; a second convex strip is disposed above each one of the first convex strips; one edge of each one of the second convex strips is fixed on the inner wall of each corresponding one of the first vertical plates; each one of the first convex strips and each corresponding one of the second convex strips form a first clamping slot, and one edge of each one of the diffuser plates (10) is inserted into each corresponding one of the first clamping slots to be fixed.
The bottom inner wall of each one of the second vertical plates has a protruding third convex strip; each one of the third convex strips is formed by protrusion or bending of the bottom inner wall surface of each corresponding one of the second vertical plates; a fourth convex strip is disposed above each one of the third convex strips; one edge of each one of the fourth convex strips is fixed on the inner wall of each corresponding one of the second vertical plates; each one of the third convex strips and each corresponding one of the fourth convex strips form a second clamping slot, and the other edge of each one of the diffuser plates is inserted into each corresponding one of the second clamping slots to be fixed.
The inner wall of each one of the second vertical plates extends to form a second flat plate 5; each one of the second flat plates is positioned above each corresponding one of the fourth convex strips; and every two adjacent rims are fixed by mutually welding the second flat plates thereof. One edge of each one of the second flat plates is fixed on the inner wall of each corresponding one of the second vertical plates, and the other edge of each corresponding one of the second flat plates is fixedly connected with each corresponding one of the third flat plates 6. One edge of each one of the third flat plates is fixed with each corresponding one of the second flat plates, and the other edge of each corresponding one of the third flat plates is fixed on the inner wall of each corresponding one of the first vertical plates. Each one of the third flat plates is positioned above each corresponding one of the second convex strips.
Each one of the third flat plates has a groove on the lower surface; each one of the LED light bars has a plurality of through-holes 33; and the screws pass through the through-holes on the LED light bars and are fixed in the grooves. The lower surface of each one of the third flat plates is a little larger than the surface of each corresponding one of the LED light bars. A distance is kept between each one of the LED light bars and each corresponding one of the second flat plates. To weld two adjacent rims is to mutually weld and fix the second flat plates thereof. During installation, the outer side face 7 of each one of the LED light bars deviates from the weld joint of each corresponding one of the second flat plates, thus facilitating the welding between rims and preventing burrs and welding spots at the weld joints of the second flat plates from roughing up the LED light bars and affecting the light uniformity at the same time. The distances between the LED light bars and the diffuser plates are 3.5-5cm. In this embodiment, the distances are 4.3cm.
Between every two adjacent LED light bars, the first LED light bar 30 has an upper surface which is leveled with the upper surface of the second LED light bar 31 in height. In the frame, the leveling of the upper surfaces of the four LED light bars in height is beneficial to the formation of uniform lighting rays and the reduction of dark spots. The end face of the first LED light bar is leveled with the side face of the second LED light bar. A light bulb 32 disposed at the end portion of the first LED light bar is linearly connected with a light bulb disposed on the second LED light bar, and the end face of the second LED light bar fits the side face of the first LED light bar. Through the linear arrangement of the light bulbs 32, the light bulbs disposed at the corners of the frame avoid the existence of dark spots. The traditional line light has no light bulb at the corners which are formed by every two adjacent rims.
The electrical soldering connection between every two adjacent LED light bars can reserve more space. The LED light bars of the traditional line lights are electrically connected through wires. The wires reduce the joining space between every two adjacent rims and bring inconvenience to installation, and the wires can block the light rays radiated by the light bulbs, and tend to make the LED light bars staggered and uneven, thus generating dark spots.
Each one of the first flat plates extends to form a fourth flat plate (13), and each one of the fourth flat plates extends out from the top outer wall of each corresponding one of the second vertical plates. In use, the whole frame is placed on a keel through the fourth flat plates, and then a decorative plate such as a plasterboard is placed on the first flat plates. The whole frame does not affect the installation of the original keel and plasterboard.
