Summary of the invention
(1) Fa Ming purpose
The present invention aims to provide a kind of have high light efficiency, high light intensity, high illumination and the concrete light-emitting diode that amasss little, easy to use and excellent one-tenth multiple light courcess capable of being combined (array light source).
Adopt " the compound eye light-emitting diode " of bionics techniques invention to solve the light loss that existing light-emitting diode exists effectively among the present invention.And be combined into the problem that multiple light courcess (array light source) upward exists.
(2) principle of invention institute foundation
The present invention institute is according to insect compound eye principle (as figure two), and the optical texture of ommatidium (as figure three).Compound eye is made up of many ommatidiums 31, and the optical texture of ommatidium 31 (as figure three) is to constitute keratoscope 21 by hexagon convex lens (being attached with transparency cornea 23 on these convex lens), and cornea is connected with circular cone crystal 22 32 times, the optical transmission principles of ommatidium 31; Light source is transferred to conical crystal 22, keratoscope 21 and circular cone crystal 22 through keratoscope 21 and all has printing opacity and optically focused effect, and the optical transmission after the convergence is to looking official's cylinder (claiming the vision cylinder again) 24 back perceived light signals.
The combination of many ommatidiums 31 just constitutes the compound eye (as figure two) of insect, and the object image that compound eye such as same big convex lens insect compound eye are seen is combined by each ommatidium 31, and promptly each ommatidium 31 can only be seen the part of this object image.
(3) the compound eye light-emitting diode constitutes substantially
The present invention is according to the basic principle of insect compound eye optical texture, and in conjunction with the characteristics of light-emitting diode, " compound eye light-emitting diode " invented in utilization " principle that light path is reversible ".It is made of light-emitting diode, reflector and lens packages body.
Implementation procedure: earlier in two through holes, reflector bottom, bonded adhesives on the point then with the pin of LED support in the packaged light-emitting diode, passes two through holes of reflector bottom, the then bonding bonding plane that solidify to form.After parts embedding transparent epoxy after solidifying solidified, make it to be shaped to " the compound eye light-emitting diode " of regular hexagon or rectangle or circular lens packages body.Lens can be herein: spherical convex lens, aspheric surface convex lens, level crossing and concave mirror.
Basic demand: the center of light-emitting diode, reflector and lens packages body should overlap or approximate the coincidence; The luminous position of light-emitting diode chip for backlight unit should be less than or equal to the focal length of lens.
The compound eye light-emitting diode is applicable to the semiconductor light emitting chip of optical wavelength 360 nanometers～760 nanometers and is the formed complex light of excitation energy source with the semiconductor light emitting chip.
