Point condensing device

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.

Problems solved by technology

[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). The illuminance is not enough, and the irradiance of the light will be uneven in the target area irradiated by the point-shaped concentrating device

Therefore, in order to solve the situation of insufficient illumination of the light source, the method of increasing the power of the light-emitting element (such as the LED element) is generally adopted, so that the LED element is in a full-load or close to full-load working state. However, in such a working state, the LED element uses The lifespan will be significantly reduced, and the problem of uneven irradiance is still not well resolved; in order to solve the problem of uneven irradiance, a layer of film-like parts that can evenly scatter light can be added at the position where the light is emitted to improve some Uniformity of irradiance, but adding such film-like parts will reduce the light transmittance and reduce the irradiance of light

Therefore, the high irradiance and high uniformity of light in the concentrating device in the prior art cannot be achieved at the same time
