Abstract
The utility model discloses a multiple lens system for LED lamp, an integral collection of a plurality of lenses made of material with good light transmission property (e.g. resin, glass and other similar materials), particularly suitable for LED lamp made in the form of collective reflecting chamber. LED chips (1) are pre-positioned at the centers of the individual collective reflecting chambers (2). In the multiple lens system (3) for LED lamp, the center-to-center distance of the lenses equals to the center distance of the collective reflecting chambers (2). The multiple lens system (3) is positioned at an appropriate position above the individual reflecting chambers of the collective reflecting chambers (2) and the centerline of the lenses in the multiple lens system (3) coincides with the centerline of the corresponding reflecting chambers in the collective reflecting chambers (2). Due to the optical properties, the change of the geometric parameters of the lens enable the adjustment of the emission angle of the LED chip below, hence better lighting effect of the LED lamp in certain area. For the so-called flat LED lamp fabricated otherwise without the collective reflecting chamber, the use of the multiple lens system will produce the same good effect. With the integrally fabricated multiple lens system, the utility model has the advantages of easy installation and operation, good consistency, and facility for mass production of the LED lamp.
Description
Affiliated technical field
The utility model relates to a kind of optical lens, promptly a kind of LED lamp poly-lens collection lens.
Background technology
Lens are widely used in light emitting diode.Most light emitting diodes all is manufactured with lens at its head when encapsulation.Do like this except beautifying the outward appearance of light emitting diode, the main optical property of utilizing lens increases certain regional photechic effect.When the lighting use, the used led chip of lamp can be a lot, and lens of all installations of equidistant directly over each chip, axially parallel are not only a difficulty but also a time-consuming thing.Application number is 2005200330811, the Chinese patent that is entitled as " a kind of LED lamp convergence reflex chamber ", the convergence reflex chamber that provides a kind of LED of being used for lamp to make, it is that the aggregate of the light reflection cavity of many cup-shapeds of making intensive on metal material is so-called convergence reflex chamber, because reflective, the optically focused effect of reflection cavity make that the lighting effect of LED lamp is greatly improved in a certain zone.If lens respectively are installed directly over each reflection cavity in above-mentioned convergence reflex chamber, will further improve the photechic effect of LED lamp, by changing the physical dimension of lens, just can raise the optical effect of controlled LED lamp, thereby reach the optimal illumination effect in a degree.
Summary of the invention
The purpose of this utility model is the so-called LED lamp poly-lens collection lens that matches and use in the LED lamp convergence reflex chamber that provides a kind of with above-mentioned, further strengthens the illuminating effect in a certain specific region.
The technical solution that the utility model proposes is: with the aggregate of light transmission excellent material (for example resin, glass etc.) the some lens of integral manufacturing, it is so-called LED lamp poly-lens collection lens, the physical dimension of lens (as size of radius of curvature, lens etc.) is decided according to different needs, spacing in spacing between each lens and the supporting with it convergence reflex chamber between each reflection cavity equates that the mounting distance between lens and reflection cavity depends on the needs.
The beneficial effects of the utility model are, have solved in the illuminating LED lamp is produced, the technical problem that lens respectively are installed of equidistant directly over each chip, axially parallel.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the vertical section structure schematic diagram of first embodiment of the utility model.
Fig. 2 is the vertical section structure schematic diagram of second embodiment of the utility model.
1.LED chip among the figure, 2. convergence reflex chamber, 3. collection lens, 4. substrate.
The specific embodiment
In accompanying drawing 1, in each reflection cavity in convergence reflex chamber 2, be positioned at the center of reflection cavity bottom, preset led chip 1, led chip 1 both can be single chips here, can also be multiple chips, depended on the needs.LED lamp poly-lens collection lens 3 is fixed in the appropriate location, top in convergence reflex chamber 2.Contained lens number is identical with the number of contained reflection cavity in the convergence reflex chamber 2 in the collection lens 3, and the position is corresponding one by one.Correspondence is promptly one by one in so-called position: in the centre-to-centre spacing in the collection lens 3 between each lens and the convergence reflex chamber 2 between each reflection cavity centre-to-centre spacing equate because led chip 1 is the center that is preset at each reflection cavity bottom in the convergence reflex chamber 2.Therefore, in the collection lens 3 in the center line of each lens and the convergence reflex chamber 2 centre-to-centre spacing of the led chip 1 of each reflection cavity also equate, the central lines of corresponding each reflection cavity in the center line of each lens in the collection lens 3 of back and the convergence reflex chamber 2 is installed, so just guarantee each lens and below it relative position between corresponding each reflection cavity in full accord.The physical dimension of each lens in the collection lens 3 (as radius of curvature, lens size etc.) is then decided according to the use needs, the radius of curvature difference of lens, and the angle of departure of the light that led chip 1 is sent is just different.Therefore, just can adjust the illuminating effect of LED lamp in our needed zone, make it to be more suitable for our requirement by the radius of curvature that changes lens.
Because the centre-to-centre spacing in the collection lens 3 between each lens equates with each reflection cavity centre-to-centre spacing in the convergence reflex chamber 2, this has just guaranteed the smooth, accurate of all lens positions in the installation process, thereby can increase substantially illuminating effect.
So-called plane LED lamp for the mode that does not adopt the convergence reflex chamber is made adopts the related collection lens of the utility model, can receive good effect state equally.Accompanying drawing 2 is exactly the structural representation of the LED lamp of this form, is another embodiment of the present utility model.
In accompanying drawing 2, the well-regulated led chip 1 that presets N unit on the substrate 4, the LED lamp poly-lens collection lens 3 that together is made of the aggregate integral manufacturing of N lens is fixed in appropriate location, led chip 1 top, and the center line of each led chip 1 coincides on centre-to-centre spacing in the collection lens 3 between each lens and the substrate 4.The center line of alleged here led chip 1 is meant the vertical line through the center of leaving the zone of presetting led chip for, for example stays the zone for circular, be the vertical line in the center of circle, as be rectangle, and then be the vertical line of rectangle diagonal intersection point.Equally, just can adjust the illuminating effect of LED lamp, make it to be more suitable for our requirement in our needed zone by the radius of curvature that changes each lens in the collection lens 3.
The utility model can improve illuminating effect owing to used the so-called LED lamp poly-lens collection lens of integral manufacturing in our needed a certain zone.In addition,, the poly-lens collection lens make fitting operation simpler because being integral manufacturing, and high conformity, help the LED lamp and make in batches.
