Description

Technical Field

[0001] The invention belongs to the technical field of lamps and relates to an anti-glare structure, and in particular to an anti-glare lens structure for an LED lamp and an anti-glare LED lamp. Background Art

[0002] In the past decade, the lighting industry, one of the important electrical industries, has undergone disruptive changes. The most important thing is that the light source has undergone a major change, and LED light sources are now widely used. Moreover, the performance of LED light sources far exceeds that of the past HID light sources. LED lamps are currently widely used in lighting design and are widely used in various occasions. They have the characteristics of high light efficiency, good color rendering, no flicker, instant start, and no fear of vibration.

[0003] Compared with light sources such as HID and incandescent lamps, the efficiency of LED light sources in LED lamps is very high, generally reaching 140lm / W. However, unlike the HID gas discharge lamp light source commonly used in the past, the light bead is very small, and the optical design method of the emitter for light flux distribution of HID lamps is usually not used. HID light sources are generally large, and the emitters of HID lamps for light distribution are usually large. Different light distribution curve requirements will require different emitters to cooperate. Different HID light source powers or HID light source types will also require different emitters. In general, there are many types of emitters for HID lamps, and the size of the lamps is also large.

[0004] The LED light beads used in LED lamps are very small, and the volume of the corresponding optical components for light distribution can also be very small. Generally, components such as lenses 101' corresponding to the LED light beads distributed on the flat plate 100' are used, as shown in Figure 1. Although the LED light beads are very small, the luminous brightness is very high, resulting in extremely high surface brightness of the lens 101'. In addition, the LED light beads are generally 1W-5W, and usually dozens of LED light beads are used in lamps, which results in a large luminous surface. And because the glare of the lamp is proportional to the brightness of the light source and the size of the luminous surface. This causes LED lamps to generally produce severe uncomfortable glare, and even disabling glare. Especially for frame-type workshops installed in chemical plants, the glare has a greater impact on operators due to the low installation height and the small shading angle of the LED lamps.

[0005] In view of the glare problem that LED lamps are prone to, the traditional emulsified glass cover method can solve the glare defect, but it is difficult to meet the light distribution requirements of LED lamps. In addition, there is also a method of using a reflector to increase the shading angle, but it requires the reflector to be deeper and the cost is very high. Therefore, how to make LED lamps meet the requirements of optical light distribution and achieve the purpose of anti-glare has become a technical dilemma. Summary of the invention

[0006] In order to solve the above problems in the prior art, the present invention is committed to developing the optical design of LED lamp lenses and proposes an anti-glare lens structure for LED lamps and an anti-glare LED lamp, which can solve the problem of glare damaging on-site workers and affecting work efficiency, and at the same time can also meet the optical light distribution requirements of on-site LED lamps.

[0007] To achieve the above object, the present invention adopts the following technical solutions:

[0008] The first aspect of the present invention is to provide an anti-glare lens structure for an LED lamp, comprising an anti-glare lens mounted on an LED substrate structure, the anti-glare lens comprising:

[0009] lens substrate;

[0010] At least one optical bead lens disposed on the lower end surface of the lens substrate;

[0011] At least one optical bead groove is provided on the upper end surface of the lens substrate, wherein the optical bead groove and the optical bead lens are arranged in a vertical correspondence; and

[0012] At least one annular anti-glare column is arranged on the lower end surface of the lens substrate, and the annular anti-glare column is sleeved on the outer side of the optical bead lens.

[0013] Furthermore, in the anti-glare lens structure for the LED lamp, the upper and lower end surfaces of the lens substrate are in a flat, curved, or arcuate shape or any other regular or irregular shape.

[0014] Furthermore, in the anti-glare lens structure for LED lamps, the shape of the lens substrate is circular, square, triangular or any other regular or irregular shape.

[0015] Furthermore, in the anti-glare lens structure for the LED lamp, the inner reflective surface of the annular anti-glare column is a parabolic surface or a hyperbolic surface structure.

[0016] Furthermore, in the anti-glare lens structure for the LED lamp, the outer scattering surface of the annular anti-glare column is a thin prism-shaped prism arranged along its circumference.

[0017] Furthermore, in the anti-glare lens structure for the LED lamp, the overall shape of the inner reflective surface of the annular anti-glare column is circular, square or any other regular or irregular shape.

[0018] Furthermore, in the anti-glare lens structure for the LED lamp, the height of the annular anti-glare column is greater than the height of the bead lens.

[0019] Furthermore, in the anti-glare lens structure for LED lamps, the depth of the light bead groove is less than the thickness of the lens substrate.

[0020] Furthermore, in the anti-glare lens structure for LED lamps, the depth of the light bead groove is greater than the thickness of the lens substrate and extends into the light bead lens.

[0021] Furthermore, in the anti-glare lens structure for the LED lamp, the light bead lens, light bead groove and annular anti-glare column of each group are arranged in concentric circles.

[0022] Furthermore, in the anti-glare lens structure for LED lamps, several groups of the annular anti-glare columns are distributed in a single circle, a square or a circular ring.

[0023] Furthermore, in the anti-glare lens structure for LED lamps, the lens substrate, the light bead lens, the light bead groove and the annular anti-glare column are an integrated structure.

[0024] A second aspect of the present invention is to provide an anti-glare LED lamp, comprising:

[0025] An anti-glare lens as described above; and

[0026] An LED substrate structure is provided with LED lamp beads, wherein the LED lamp beads are correspondingly embedded in the light bead grooves of the anti-glare lens.

[0027] The present invention adopts the above technical solution, and has the following technical effects compared with the prior art:

[0028] (1) The structure design of the concentric arrangement of the light bead lens and the annular anti-glare column is adopted. The light from the LED light source emitted by the LED light bead is received by the annular anti-glare column and distributed to the corresponding direction after refraction by the light bead lens and the annular anti-glare column. This not only improves the shading angle to achieve the purpose of anti-glare, but also meets the optical light distribution requirements of the LED lamps on site;

[0029] (2) The inner reflective surface of the annular anti-glare column adopts a parabolic or hyperbolic structure design, so that the light incident on the inner reflective surface is refracted onto the working surface, which improves the optical efficiency while reducing the light passing through the cylindrical anti-glare structure, greatly reducing the generation of uncomfortable glare or disabling glare;

[0030] (3) By arranging fine prisms on the outer periphery of the annular anti-glare column, the light incident on the annular anti-glare column is refracted by the fine prisms, thereby reducing the brightness and the degree of uncomfortable glare or disabling glare;

[0031] (4) The LED lamp uses an anti-glare lens structure with a simple structure and novel design. It can match different LED substrate structures and has a wide range of applications. It effectively solves the problem of glare damaging on-site workers and affecting work efficiency, while meeting the optical light distribution requirements of on-site LED lamps.
