Abstract

The invention belongs to the technical field of condensation, and particularly relates to a point condensing device. The device comprises a light emitting device, a condensing lens and a light guide lens, wherein the condensing lens is arranged above the light emitting device; the light guide lens is arranged on the condensing lens; the condensing lens and the light emitting device are rotors, and center axes of the condensing lens and light guide device are arranged on the same line; the light guide lens comprises a light guide disc and a light guide column which is connected with the light guide disc into a whole; and light emitted from the light emitting device sequentially passes through the condensing lens and the light guide lens and is uniformly exported in point shape. The light emitting device, the condensing lens and the light guide lens are matched, so that a light emitting element with relatively small power can achieve the effects of high irradiance and high uniformity; and the device is formed by simple parts, so that cost can be greatly reduced.

Description

technical field

[0001] The invention belongs to the field of light concentrating technology, in particular to a point-shaped light concentrating device. Background technique

[0002] In the field of light sources for industrial use, in order to obtain good illuminance, it is usually necessary to gather the light emitted by the illuminant into a point shape, but the existing point-shaped light-gathering device has a relatively poor light-gathering effect (that is, light utilization efficiency). As a result, the illuminance is insufficient, and the phenomenon of uneven irradiance of light will appear in the target area irradiated by the point-like concentrating device. Therefore, in order to solve the problem of insufficient illumination of the light source, the method of increasing the power used by light-emitting elements (such as LED elements) is generally adopted, so that the LED elements are in a full-load or close to full-load working state. The lifespan will be signifi...
