Abstract
The invention discloses an integrated LED lamp. The integrated LED lamp comprises a PCB, a plurality of LED lenses evenly distributed along the PCB and a luminous component coupled with the LED lenses. Each LED lens is a solid body made of transparent materials and comprises a bottom surface, an inner curved surface and an outer curved surface, wherein the inner curved surface and the outer curved surface surround the bottom surface and extend in the vertical direction, the periphery of the inner curved surface is concaved upwards to form a first optical curved surface, the first optical curved surface is a light incident plane, the outer curved surface comprises four second optical curved surfaces which are spliced, the periphery of each second optical curved surface extends upwards along the bottom surface, and each second optical curved surface is a light refraction plane. The luminous component is arranged inside the inner curved surface, a rectangular light spot with uniform luminance can be formed, and therefore the integrated LED lamp is more reasonable and better in effect.
Description
Technical field
The present invention relates to a kind of integrated LED lamp.
Background technology
Existing integrated LED lamp, scioptics are to carrying out secondary light-distribution from LED light out, to reduce the use amount of LED, meet the requirement of briliancy and homogeneity simultaneously, integrated LED lamp in the market, the peripheral profile of its optical texture part top view projection is mostly circular, and its optical texture partial shape is mostly Rotational Symmetry form, and therefore existing hot spot is all circular.
Summary of the invention
The object of the invention is to overcome the defect existing in prior art, provide one can form rectangular light spot, more rational integrated LED lamp.
For achieving the above object, technical scheme of the present invention has been to provide a kind of integrated LED lamp, comprise pcb board, along the equally distributed LED lens described in several of described pcb board, the luminous component being coupled with described LED lens, described LED lens are entities of being made up of transparent material, comprise bottom surface, the negative camber and the positive camber that extend at vertical direction around described bottom surface, described negative camber surrounding is upwards recessed to form the first optical surface, the first described optical surface is light entrance face, described positive camber comprise four surroundings along bottom surface upwardly extending the second optical surface being spliced mutually, the second described optical surface is refractive optical surface, described luminous component is arranged in described negative camber.
As preferably, described bottom surface is perpendicular to axis.
As preferably, described negative camber is positioned at lens centre.
As preferably, described negative camber is half elliptic.
As preferably, it is made up of glass or optical resin material.
As preferably, described pcb board has several, and is arranged in parallel.
As preferably, described pcb board equidistantly arranges.
Advantage of the present invention and beneficial effect are: can form the rectangular light spot of a uniform illumination, and more reasonable, better effects if.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention;
Fig. 2 is LED lens and luminous component schematic diagram.
Wherein: 1, pcb board; 2, LED lens; 3, luminous component.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is further described.Following examples are only for technical scheme of the present invention is more clearly described, and can not limit the scope of the invention with this.
As Fig. 1, shown in Fig. 2, a kind of integrated LED lamp, comprise pcb board 1, along the equally distributed LED lens 2 described in several of described pcb board 1, the luminous component 3 being coupled with described LED lens 2, described LED lens 2 are entities of being made up of transparent material, comprise bottom surface, the negative camber and the positive camber that extend at vertical direction around described bottom surface, described negative camber surrounding is upwards recessed to form the first optical surface, the first described optical surface is light entrance face, described positive camber comprise four surroundings along bottom surface upwardly extending the second optical surface being spliced mutually, the second described optical surface is refractive optical surface, described luminous component is arranged in described negative camber, described bottom surface is perpendicular to axis, described negative camber is positioned at lens centre, described negative camber is half elliptic, it is made up of glass or optical resin material, described pcb board 1 has several, and be arranged in parallel, described pcb board 1 equidistantly arranges.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
