Abstract
The utility model relates to a high brightness luminescence device, relating to a luminescence device which uses light emitting diodes as a light source. The utility model is composed of a box body, lenses, and a light source. The front side and the rear side of the box body are respectively provided with a lens shelf and a light source shelf. The lenses are convex lenses or fresnel lenses, and are installed on the lens shelf. The light source is the light emitting diodes, and the number of the light emitting diodes is same as the number of the lenses. The light emitting diodes are corresponding to the lenses one to one, and are installed on primary optical axes on the rear of lenses. A power supply is a direct current power supply such as a dry battery, a storage battery or a rectifying power supply, and is introduced from the rear side of the light source shelf. The utility model has the advantages of simple structure and high and uniform brightness. Thus, the utility model is especially suitable for being used as various light signal devices or various directional illumination devices.
Description
It is the light-emitting device of light source with the light emitting diode that the utility model relates to a kind of.
Light emitting diode be a kind of be the cold light light source of power supply with the direct current, versicolor light emitting diode not only is widely used as various pilot lamp, but also a plurality of light emitting diode combined can be become optical signal device or directional lighting device, for example be used for the searchlight signal lamp of railway and aviation field and be used for the projection lamp that large-screen is thrown light on.The optical signal device or the directional lighting device that in the prior art with the light emitting diode are light source directly adopt light emitting diode mostly and do not take any other optically focused measure, thereby the dispersion angle of its light beam is bigger, not only had a strong impact on the brightness of optical signal device and directional lighting device, and the homogeneity of sight field is also very poor, finally all will directly influence the result of use of optical signal device and directional lighting device.
The purpose of this utility model promptly is to the suitable in addition improvement of structure that with the light emitting diode is the light-emitting device of light source, to improve its brightness and to improve its light field homogeneity.
To achieve these goals, the utility model is all installed convex lens or Fresnel lens in the place ahead of each light emitting diode, to be focused to directional light or reduce its dispersion angle behind light beam process convex lens that light emitting diode sends or the Fresnel lens, thereby improve its brightness significantly and improve its light field homogeneity.Be described in further detail below in conjunction with the technical characterictic of specific embodiment the utility model high brightness luminescence device.
Accompanying drawing 1,2 is respectively the structural representation and the front view of the utility model high brightness luminescence device.
With reference to the accompanying drawings 1,2, the utility model high brightness luminescence device mainly is made of box body, lens and light source.Box body 1 is the carrier that is used to install and fix lens and light source, and its front side and rear side have lens mount 2 and the light source shelf 3 that is used to install lens and light source respectively.The shape of box body can be designed to various pattern according to different use occasions.For example, during as portable signal lamp, mine lamp or electric torch, box body can be designed to tubular, and during as searchlight signal lamp or large-screen projection lamp, box body should be designed to cuboid.Lens 4 comprise at least one convex lens or Fresnel lens, are installed on the lens mount 2, and its multiplying power should be selected according to service condition.The shape of lens can be circle, and square or regular polygon should be selected as the case may be.For the light-emitting device that only adopts lens, round lens obviously is optimal selection; For the light-emitting device that is formed by a plurality of combination of lensess, square or regular polygon (as regular hexagon) lens help the assembly group most.Light source 5 is a light emitting diode, its number is identical with the lens number and corresponding one by one with lens, be fixed on by light source shelf 3 on the primary optical axis at each lens rear, its power supply can adopt direct supplys such as dry cell, accumulator or rectifier power source and introduce from light source shelf 3 rear sides.
The utility model is simple in structure, and brightness height and light field are even.Experiment shows, adopting multiplying power is that 3.5 Fresnel lens can make the luminance brightness of light emitting diode improve more than 6 times.Therefore, the utility model is particularly suitable for as various optical signal devices or directional lighting device.
