Lens structure for illumination

The present invention relates to a lens structure for illumination, in particular to a multi-focal curved surface formed by a loop curve adjacent between a first surface and a second surface of a lens body, which can control the traveling path and light pattern of light irradiation. .

According to the current lighting source, most of the light sources use LED lights. LED lights have the advantages of energy saving and long-term use. However, when you want to increase the brightness of LED lights, more LED lights will be used. Produce a number of highlights, multiple highlights make the subject more radiant, resulting in a sense of blur, which is prone to eye fatigue. Therefore, the use of lighting fixtures with lenses is the best way to increase the brightness of LED lights.

The patent case of the Republic of China No. M343112 "Light-emitting diode lamp with interchangeable lens" is mainly provided with a light-emitting diode assembly in a lamp cup, and a lamp with a circuit board is arranged at the rear end of the lamp cup. a lamp cup cover having a light exit hole is arranged at the front end of the lamp cup, wherein the light exit hole is provided with a detachable lens at the front end of the light emitting diode, and the lens can be multi-styled shape or color to make the light Diode luminaires offer a variety of decorative lighting and multiple appearances by replacing different lenses.

The conventional lens is a convex lens, and the convex light of different arcs is used to change the light projected by the light-emitting diode, but the change of the light can only change the distance and the area of the projected light, and the path of the light cannot be Variability, for example: the headlights or bicycle lights require a downward light to illuminate the road, but the current light is still based on the ring's scattering, so half of the light source escapes above the luminaire and even affects the user. The sight of the line, the danger of driving.

This creation system can solve the problems that the lens for conventional illumination is difficult to accurately control the range of light, the brightness, and the source of the projection does not change.

The lens structure of the present invention is provided with a lens body having a first surface and a second surface. The first surface and the second surface are adjacent to a loop curve, and the loop curve is symmetrical. The arc line is combined, and the line segment presented by the two arc lines has a first end point, a midpoint and a second end point, so that the first surface forms a multi-focal surface.

The lens structure for the illumination of the present invention, wherein the first end point to the midpoint of the lens body is a relatively flat first arc segment, and the middle point to the second end point is a second arc extending backward Section.

The lens structure for the illumination of the present invention, wherein the first end to the midpoint and the second end point to the midpoint of the lens body are arc segments extending from a symmetrical two-way midpoint.

The lens structure for the illumination of the present invention, wherein the inner side of the lens body is provided with an alcove.

The lens structure for the creation illumination can be combined with the lens body, and the lamp is provided with a lamp holder and an LED light source, and the lamp is a lamp, a street lamp, a flashlight, a searchlight and the like.

The lens structure used in the creation of illumination has the following advantages:
1. Using LED light source, whether it is single crystal LED light source or polycrystalline LED light source, there are multi-focal curved surfaces that can be formed by the loop curve of the lens body, and the light source is evenly distributed and effectively controlled to the desired position. There is no need for a matte to assist in creating a cut-off line, which loses overall brightness.
2. Use this creation to reduce the number of LED light sources used to reduce costs.
3. The use of LED light source can reduce heat source generation, extend the life of LED, and improve product competitiveness.
4. Through the multifocal surface formed by the loop curve of the lens body, the light type can be controlled to be elliptical, round or semi-circular, so as to be suitable for various environments.
5. The lens body of the present invention can effectively distribute the light source evenly, and can improve the blurring feeling of multiple light and light of the general multi-light source, so that the eyes are not too tired.
