Abstract
The utility model relates to an LED luminescent device for a shadowless lamp, comprising an LED light source assembly and a reflection condensing system. The reflection condensing system is composed of a paraboloid reflector and a light spot adjusting device. The LED light source assembly is connected to the light spot adjusting device. A hand-operated light spot adjusting device can drive the LED light source assembly to move along the axis of the paraboloid reflector. The LED light source of the LED light source assembly is composed of two or more than two LED light sources which can be independently controlled, an integral lens and a radiator. The LED light source assembly is disposed below the axis of the paraboloid reflector. The LED light source encircles and is fixed to the outer cylindrical face of the radiator, and the integral lens is buckled to a substrate of the LED light source. The LED luminescent device for a shadowless lamp is advantageous in that the LED luminescent device can be widely applied in various fields of indoor and outdoor decoration, illumination, traffic and safety display, and especially an operation work room; The problems of a conventional operating room that service lifetime of an energy-saving lamp is short, and efficiency is low can be resolved.
Description
Technical field
The utility model relates to a kind of LED electricity-saving lamp, especially a kind of LED light-emitting device for shadowless lamp.
Background technology
Give the energy of the limited use in ground constantly nervous in the present world, most countries is all being advocated the energy-conserving and environment-protective theory, seek novel energy and replace non-renewable resources, and under the state of existing LED light emitting diode, though have advantages such as energy-conservation, that the life-span is long, but also be not enough to solve the adverse consequences that existing LED lamp brings, according to patent retrieval to H01J61|00(2006.01) the I utility model patent, what solve is aesthetic on decorating.Use the very big shortcoming of existence at medical electricity-saving lamp, have the power consumption height, the life-span is short partially, and mortality weakness such as radiation are arranged.Add the limitation owing to the LED technology, what LED operation shadowless lamp lamp holder generally adopted at present is that matrix form is arranged LED, synthesizes required no shadow effect, and it is big to have the development and Design difficulty, structural manufacturing process complexity, installation and maintenance difficulty.
Operation shadowless lamp mature technique the most is overall reflective formula halogen shadowless lamp, be characterized in Stability Analysis of Structures, safeguard that efficient and convenient, light spot shape is mellow and full evenly, the light beam degree of depth is big, color reducibility is excellent, but be subjected to the defective effect of halogen light source own, light source life is short, power consumption is big, luminous efficiency is low etc., and substituted trend is gradually arranged.In recent years, along with the development of LED technology, the application of LED technology on operation shadowless lamp is also with the fastest developing speed, and adopting LED is that light source life overlength, energy-conservation, colour temperature are convenient to control, direct current and are not had stroboscopic, no ultraviolet is infrared as the characteristics of light emitting source.Because many excellent specific properties of LED lamp, so the LED lamp is the inexorable trend of operation shadowless lamp development as the operation shadowless lamp new light sources.
The utility model content
[0003] technical problem that solves of the utility model is to provide a kind of LED light-emitting device for shadowless lamp, to solve the deficiency in the above-mentioned background technology.
Above-mentioned purpose of the present utility model realizes by following technical scheme:
A kind of LED light-emitting device for shadowless lamp comprises led light source assembly, reflecting condensation system, and it is characterized in that: the reflecting condensation system is made up of parabolic mirror and hot spot adjusting device etc.; The led light source assembly links to each other with the hot spot adjusting device; The led light source assembly is made up of two groups or more led light source that can independently control, overall lens and radiator; The led light source assembly is positioned at parabolic mirror axis lower position; Led light source is around being fixed in the radiator periphery, and overall lens is buckled on the substrate of led light source, and the light that led light source sends behind overall lens, is projected to parabolic mirror; Manually the hot spot adjusting device can drive the led light source assembly and do displacement along the axis of parabolic mirror.
Described light-source system links to each other with regulating system.
Described light-source system mainly is made up of some groups of led light sources, overall lens, radiator.
Described overall lens is made by the acrylic light transmissive material, is semi-circular.
Described radiator is made by the aluminium section bar of light face cylindrical.
The utility model advantage compared with prior art is: some groups of LED annular spread are in parabolic mirror axis below, and are simple in structure easy to control; It is relatively independent that each organizes LED, and the coordinating and unifying can form anti-failure system; Described overall lens can make the successive layer of each arbitrary source, in the time of focused ray, effectively weakens ghost effect.
