[0028] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
[0029] like Figure 4-6 As shown, a schematic diagram showing the structure of a single LED light source board 2 and three single LED light source boards 2 combined into one component in the prior art and the existing triangular dark area ( Figure 6 The light intensity of the circled area is significantly lower than that of other areas).
[0030] like Figure 1a-2 As shown, the LED light source board in one embodiment of the utility model can be used alone (such as Figure 1a As shown) and a driving circuit to form a light source, or multiple light source panels (such as Figure 2 The three combinations shown) are spliced and then connected to the drive circuit to form a larger-scale LED light source.
[0031] The LED light source board 1 at least includes a loading plate and LED lamp beads 13 arranged on the loading plate. The loading plate includes a board head 11 and a board body 12 located near the center position in sequence. When observed in a direction perpendicular to the loading plate, the board body extends in a nearly spiral clockwise or counterclockwise direction. The board body includes a radius gradient portion and a transition structure 14 connected between two adjacent radius gradient portions. When observed from the board head to the tail end of the board body, the inner diameter of the board body at the rear side of the transition structure is increased compared to that before the transition structure (it should be noted that the increase here is not gradual, but sudden). To satisfy the combination of N light source boards, N is a positive integer greater than 1. In the combined state, the tail end of the board body of one light source board is located within the range defined by the outer edge of a transition structure of another light source board, so as to satisfy: in the combined state, all the outermost LED lamp beads 13 including the last lamp bead 13 at the tail end are approximately arranged on the same circumference. Figure 1a and 1b What is shown is a possibility that N is 3, that is, the transition structures at different radial positions or the tail ends of the plate body form an angle of 120°.
[0032] Depend on Figure 1a As can be seen in the figure, in order to meet the requirement that the tail end matches the transition structure 14 of the board body at the outermost side, the transition structure matching therewith will form a space for accommodating the tail end, so that the two can complement each other in light radiation effect, and the effect can be as follows: Figure 3 As shown, although there are still differences in light intensity distribution, this intensity difference is much smaller than that of the prior art solution.
[0033] In such Figure 2 In the combined form shown, the tail end can be embedded in the space defined by the transition structure of another adjacent LED light source board 1, so that not only the structure is complementary, but also the light effect is further complementary, thereby further eliminating Figure 3It can be seen that the inner convex structure and the outer convex structure are sorted from the tail end to the board head and marked as Je and Ke in sequence, where e is a natural number. In the combined state, it satisfies that the inner convex structure Je formed by the transition structure on the outer loading board is in the same shape as the outer convex structure K(e+1) formed by the transition structure on the other loading board in the inner circle. Figure 2 It can be seen that the radial depth of the gap formed by a transition structure at the outermost edge of the LED light source board 1 is approximately the radial width of the tail end, thereby satisfying the effect that all the outermost LED lamp beads including the last lamp bead at the tail end are arranged approximately on the same circumference. Figure 7 The figure shows the light efficiency advantage of this single structure compared with the existing conventional mosquito coil structure arrangement.
[0034] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
[0035] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
