Lighting device capable of achieving maximum light collecting effect

A lighting device, in particular, a collecting lighting device that collects and projects all emitted light through a proper arrangement of a lens, a light source and a reflector, and has the advantage of maximizing the light collecting effect.

At present, the design difficulty of the lamp using the light-emitting diode is the secondary optical design. At present, a concentrating type illuminating lamp using a concentrating lens has an uneven brightness of an illumination pattern, and a phenomenon of light and dark appears. This uneven illumination has many discomforts and is likely to cause visual fatigue. How to make the LED lighting fixture provide visual and comfortable lighting effects, which is directly related to its applicability in various lighting occasions, is an important factor in its application promotion. Therefore, the industry pays more attention to this issue.

Referring to the first figure, a schematic diagram of a conventional light-emitting diode lamp. A conventional light-emitting diode lamp includes a mirror 1a, a light-emitting diode module 2a attached to the bottom side of the mirror 1a, and a flat lens 3a attached to the mirror 1a and covering the light-emitting diode module 2a. The flat lens 3a can only function as a protective light-emitting diode, and has almost no secondary optical effect, so that the secondary optical action of the light of the light-emitting diode module 2a can only be performed by the mirror 1a alone.

As shown in the first figure, when the light emitting angle of the light emitting diode module 2a is 140 degrees, only light having an emitting angle of 20 degrees to 48.59 and 131.4 to 160 degrees can be reflected by the mirror 1a. As shown in Fig. 1, only the light at the above-mentioned illumination angle can be used as the reflected light that can be controlled, and the light emitted from the remaining angles is the uncontrollable free diffused light, so the light collection efficiency is very low.

Referring to the second figure, a schematic diagram of another light-emitting diode lamp of the prior art. A secondary optical lens group 4a is disposed above the light-emitting diode module 2a, and a central portion of the secondary optical lens group 4a is a convex lens 41a, and the two sides are generally configured as a mirror, wherein the convex lens 41a is The curved reflecting surface folds the large-angle outgoing light into a small-angle outgoing light. In other words, the light-emitting diode module 2a originally emits light at a small angle by the convex surface of the secondary optical lens group 4a, and can be refracted into a smaller angle to emit light. Therefore, the convex lens can be condensed on the light emitted from the light-emitting diode module 2a at an intermediate angle range, but part of the light emitted from the two-dimensional angle of the light-emitting diode module 2a cannot be subjected to secondary optics, secondary optics. The latter brightness distribution is still bright and dark, that is, there is still the problem that the diffused light cannot be collected.

This uneven brightness of light is easy to cause discomfort and is likely to cause visual fatigue. Therefore, it is necessary to provide a lens structure that can improve the etendue, and convert the scattered light generated by the light source into a concentrated beam to achieve enhanced light uniformity and light intensity.

The main purpose of the present invention is to provide an illumination device capable of achieving the maximum light collection effect, wherein the light source emitted by the illumination source without the reflector is configured by appropriately arranging the relative positional relationship between the lens, the illumination source and the reflector. Both can pass through the lens and be collected by the lens and projected outward, so as to enhance the uniformity of light output and the intensity of light output.

In order to achieve the above object, the specific technical means of the present invention comprises a reflector; a base having a light source on the top surface, the light source being disposed at the bottom of the reflector, wherein the light emitted by the light source comprises direct injection The light beam and the indirect light beam are directly emitted from the light source and are directly emitted from the light shield without the reflector, and the indirect light beam is emitted from the light source and reflected by the reflector. Light outside the reflector

a lens disposed on the light source and in the reflector, wherein the lens is located on a light travel path directly exiting the light beam and spaced apart from the light source by a specific distance, wherein the light source is emitted at the specific distance The direct exit beam can pass completely through the lens.
