Problems solved by technology

There are many diseases that need laser therapy in hospitals. With the development of medical care, lasers are used more and more widely. Low efficiency and short service life
If imported lasers are used, the service life can be extended and the work efficiency can be improved, but the price is more expensive, so the use and development of laser therapy devices are limited to some extent

Embodiment Construction

[0014] Shown in the scattered light irradiation structure diagram of the present invention of Fig. 1, unit lens (4) collects the light that light-emitting diode (2) sends on the irradiation surface (7), and the size of irradiation surface (7) can be according to use Depends on requirements. Because the combined spherical surface (1) of the light-emitting diode (2) and the combined spherical surface (3) of the unit lens (4) are concentric spherical surfaces, axial spherical aberration is mainly generated, and the light effect is good because the aberration is very small.

[0015] As shown in the parallel light irradiation structure diagram of the present invention of Fig. 2, field lens (5) is set at the center of sphere of the combined spherical surface (3) of unit lens (4), and the light that unit lens (4) emits passes through field lens ( 5) shoot to projection mirror (6), and the focal plane of projection mirror (6) is just on the main surface of field lens (5). Therefore, ...

Abstract

The combined high efficiency light irradiation system has single wavelength LED's to replace laser, and LED's with mechanical stability and reliability higher than laser and other light source is used in cancer treating system and lighting system. Structurally, combined spheres with single lens and two concentric spheres is set between the combined sphere of LED's and the irradiated surface to obtain scattered light in the irradiated surface. When some optical integrator is set between the combined sphere of LED's and the irradiated surface, homogeneous parallel light may be obtained in the irradiated surface. The radiation intensity may be controlled by means of controlling the number of LED's in lighting.

Description

Technical field: [0001] The invention belongs to the technical field of lighting systems. Background technique: [0002] At present, most of the domestically produced laser therapy instruments use domestically produced relatively high-power lasers as light sources. There are many diseases that need laser therapy in hospitals. With the development of medical care, lasers are used more and more widely. Low efficiency and short service life. If imported lasers are used, the service life can be extended and the work efficiency can be improved, but the price is more expensive, so the use and development of laser therapy devices are limited to some extent. Invention content: [0003] The purpose of the present invention is to provide a combined high-efficiency light irradiation system. The light source is a single-wavelength light-emitting diode, and multiple light-emitting diodes can be combined to form a light irradiation system. The number of light-emitting diodes used is ...
