Description of reference numerals:
10, lens body, 110, LED lamp bead, 120, enter light face, 130, exiting surface, 20, base.
Detailed description of the invention
Below embodiments of the invention are described in detail:
(in figure, hollow out the internal structure so that LED can be illustrated at base position) as shown in Figure 1, the lensed LED of a kind of tool, it comprises lens body 10, base 20 and at least three LED lamp pearls 110, described lens body 10 is fixed on described base 20, described lens body 10 is provided with the cavity for holding LED lamp bead 110, described cavity is formed into light face 120, described lens body 10 with described enter relative face, light face 120 be exiting surface 130, described LED lamp bead 110 is discrete extension point light source, the central point line of three described LED lamp bead 110 of arbitrary neighborhood forms equilateral triangle.
The LED lamp bead 110 of the lensed LED of described tool is discrete extension point light source, and make the central point line of arbitrary neighborhood three LED lamp pearl 110 form equilateral triangle, the arrangement mode of restriction LED lamp bead 110, improve the light-out effect of LED lamp bead 110, make the continuity of its bright dipping wait until improvement, reduce the technical problem causing the concussion of distribution curve flux because of the discontinuous of light source.
A number of preferred described LED lamp bead 110 is 3N+1, and wherein, N is more than or equal to 1; All described LED lamp bead 110 line up M row, and wherein M is more than or equal to 3; M arranges described LED and arranges in the mode of specular.Described LED lamp bead 110 is arranged in the mode of specular, and the equilateral triangle that the line of centres of all LED lamp bead 110 is formed is uniformly distributed, thus make its bright dipping evenly, light mixing effect is better.The preferred M=N=3 of the present embodiment, is namely provided with 10 LED lamp pearls 110, is arranged in 3 row, and such 10 LED lamp pearls 110 arrange in the mode of 3-4-3.
The power of the preferred described LED lamp bead 110 of the present embodiment is less than or equal to 2 watts, is the LED lamp bead of middle low power, and the present embodiment preferably adopts power to be the LED lamp bead of 1.2W.The phenomenon that the present invention utilizes the LED lamp bead 110 of discrete extension point light source well to solve the uneven and hot spot edge of its bright dipping hot spot of lamp of middle low power light source to occur macula lutea.
Further preferably described in enter light face 120 and include frosted layer; Light face 120 will be entered carry out process and be slight frosted layer.Light face 120 is entered after frosted process, the light that LED lamp bead 110 sends is after the scattering of the micrograined texture of frosted, the effect of even light can be produced, make the bright dipping hot spot brightness of lamp evenly, greatly reduce even to eliminate and cause light intensity fluctuation phenomenon because of the discontinuous of light source.
