Background technique

Ceiling lamps and embedded lamps (such as ceiling spotlights, downlights, etc.) are the most common lamps in daily life, and they are usually installed in a reserved position on the ceiling in a ceiling or embedded manner for indoor lighting. The ceiling lamp or recessed lamp includes a light source and a light distribution element (such as an optical lens, a diffusion cover, a shade, etc.), and the light distribution element is arranged on the light path of the light source to allow the light source to The generated light is radiated into the indoor environment through the light distribution element. During this process, the function of the light distribution element is to scatter the light so that the light generated by the light source can be radiated as uniformly as possible.

1A and 1B disclose the first optical lens 100A provided by the prior art, the interior of the optical lens 100A is provided with a fly-eye prism group 110A, and the back of the optical lens 100A is provided with a reflective prism group 120A , and the compound eye prism group 110A corresponds to the light source. When the ceiling lamp or recessed lamp is used, the light generated by the light source will pass through the compound eye prism group 110A. At this time, the light generated by the light source is automatically divided into the first part of light and the second part of light. Part of the light, the first part of the light will directly pass through the compound eye prism group 110A to radiate to the indoor environment, and the second part of the light will be reflected by the compound eye prism group 110A to radiate to the optical lens 100A back. The set of reflective prisms 120A is reflected by the set of reflective prisms 120A again to radiate to the indoor environment. Because the first part of the light is directly radiated through the compound eye prism group 110A, this causes the first part of the light to be relatively concentrated, and further causes the glare effect of the ceiling lamp or recessed lamp, which is very important for the ceiling lamp or recessed lamp. The light quality of traditional lamps is relatively poor.

2A and 2B disclose the second optical lens 100B provided by the prior art. The inside of the optical lens 100B is provided with a fly-eye prism group 110B, and the front of the optical lens 100B is provided with a refractive prism group 130B. , and the compound-eye prism group 110B corresponds to the light source. When the ceiling lamp or recessed lamp is used, the light generated by the light source will pass through the compound eye prism group 110B. At this time, the light generated by the light source is automatically divided into the first part of light and the second part of light. Part of the light, the first part of the light will directly pass through the compound eye prism group 110B to radiate to the indoor environment, and the second part of the light will be refracted by the compound eye prism group 110B to radiate to the front surface of the optical lens 100B. The refraction prism group 130B is refracted by the refraction prism group 130B again to radiate to the indoor environment. Because the first part of the light is radiated directly through the compound eye prism group 110B, this causes the first part of the light to be relatively concentrated, and further causes the glare effect of the ceiling lamp, which has a great impact on the illumination of the ceiling lamp or embedded lamp The quality is also relatively poor.

3A and 3B disclose the third optical lens 100C provided by the prior art. A reflective cone 140C is provided inside the optical lens 100C, and a reflective prism group 120C is provided on the back of the optical lens 100A, and The reflective cone 140C corresponds to the light source. When the ceiling lamp is in use, the light generated by the light source will directly irradiate the reflective cone 140C to be reflected by the reflective cone 140C, and then reflected by the reflective prism group 120C to radiate to the indoor environment. The light intensity of the light in the central area can be effectively reduced by the reflective cone 140C, thereby achieving an anti-glare effect. However, forming the reflective cone 140C inside the optical lens 100C is extremely complicated both in the structure of the optical lens 100C and in the manufacturing process of the optical lens 100C, resulting in the optical lens 100C The high cost is not conducive to mass production of the optical lens 100C.

Fig. 4A to Fig. 4B disclose an anti-dazzling effect of the ceiling lamp through a lampshade. Specifically, in FIGS. 4A and 4B , the ceiling lamp provides a diffuser cover 200D, wherein the diffuser cover 200D is set on the light path of the light source to allow the light to pass through the diffuser cover. When 200D radiation is scattered. The diffuser cover 200D is made of plastic material or frosted glass material. Although this method can achieve anti-glare effect, the light output rate of the diffuser cover 200D is relatively low, making the light radiated through the diffuser cover 200D hazy. , which makes the user feel tired in this environment. The light source of this ceiling lamp adopts patch-type lamp beads or energy-saving lamp tubes, and the space for arrangement is relatively large. If the arrangement of the light sources is uneven, It also leads to the appearance of dark areas of light. In addition, the use of the diffusion cover 200A makes it impossible to design the beam angle of the ceiling lamp. In Fig. 5A and Fig. 5B, the ceiling lamp or recessed lamp provides a reflective cup 300D, wherein the reflective cup 300D is arranged on the light path of the light source in an inverted cone shape, so as to allow the light to pass through The reflective cup 300D is scattered during radiation. However, the use of the reflector 300D tends to cause a large amount of afterglow and the central light is too concentrated, so that the attenuation ratio of the light beam is relatively large, and the uniformity of the light after it radiates out of the ceiling lamp or recessed lamp More importantly, the use of the reflector 300D still cannot solve the problem that the ceiling lamp or recessed lamp is prone to dazzling effects.

Those skilled in the art can understand that the specific examples of the anti-glare lamp disclosed in FIGS. 6A to 7B are only illustrative descriptions, which do not limit the content and scope of the present invention. Specifically, the anti-glare lamp includes a light source 10 and an optical lens 20 .

The light source 10 is adapted to be electrically connected to an external power source to generate light. The optical lens 20 is disposed on the light path of the light source 10 to allow the light generated by the light source 10 to radiate to the external environment of the anti-glare lamp through the optical lens 20 . When the light generated by the light source 10 radiates to the external environment of the anti-glare lamp through the optical lens 20, the optical lens 20 is used to process the light generated by the light source 10, for example, the optical lens 20 The radiation path of the light generated by the light source 10 can be changed to prevent the light generated by the light source 10 from being too concentrated in the middle of the anti-glare lamp, so that the anti-glare lamp can achieve the purpose of anti-glare.

It is worth mentioning that, in the present invention, the type of the light source 10 may not be limited, for example, the light source 10 may be an LED light source or a halogen light source or other types of light sources.

The anti-glare lamp may further include a housing 30 for accommodating and installing the light source 10 and the optical lens 20 for protecting the light source 10 and the optical lens 20 . In addition, the housing 30 is also used to install the anti-glare lamp on a predetermined position such as the ceiling, so as to fix the anti-glare lamp. As shown in FIG. 6B , the central axis of the housing 30 and the central axis of the optical lens 20 can be coaxial. In this way, the optical axis generated by the light source 10 can pass through the optical lens 20 to all The surrounding area of the above-mentioned anti-glare lamps radiates evenly.

As shown in Figures 8 to 10, the optical lens 20 has a light exit surface 21 and a light incident surface 22, the light exit surface 21 and the light incident surface 22 are respectively located on both sides of the optical lens 20, so The light source 10 is arranged on the side where the light-incident surface 22 of the optical lens 20 is located, so that the light generated by the light source 10 can radiate from the light-incident surface 22 into the optical lens 20, and from the light-incident surface 22 The light emitting surface 21 radiates out of the optical lens 20 to enter the external environment of the anti-glare lamp.

The optical lens 20 is also provided with a first prism group 201 and a second prism group 202, wherein the first prism group 201 is arranged on the light-emitting surface 21, and the second prism group 202 is arranged on the The light incident surface 22 and the second prism group 202 are located on the periphery of the first prism group 201 . In a preferred embodiment of the present utility model, the first prism group 201 and the second prism group 202 can be integrally formed on all parts of the optical lens 20 when the optical lens 20 is formed. The light emitting surface 21 and the light incident surface 22 are described. In another preferred embodiment of the present utility model, after the optical lens 20 is formed, the first prism group 201 and the second prism group 202 are re-formed on the optical lens 20 The light emitting surface 21 and the light incident surface 22 are described. Nevertheless, in order to ensure the consistency of the optical properties of the various regions of the optical lens 20, the utility model is preferably that the first prism group 201 and the second prism group 202 are formed when the optical lens 20 is formed. The light emitting surface 21 and the light incident surface 22 of the optical lens 20 are integrally formed.

Further, the light outlet surface 21 has a central region 211 and an outer region 212, and the outer region 212 of the light outlet surface 21 extends from the middle region 211 of the light outlet surface 21 in a curved manner to the On the edge of the optical lens 20 , the first prism group 201 is disposed in the middle area 212 of the light emitting surface 21 . That is to say, the first prism group 201 is not provided on the outer region 212 of the light emitting surface 21 , so that the outer region 212 of the light emitting surface 21 is a smooth arc surface.

Correspondingly, the light incident surface 22 has a central region 221 and an outer region 222, and the outer region 212 of the light incident surface 22 extends curvedly from the central region 221 of the light incident surface 22 around. To the edge of the optical lens 20 , the second prism group 202 is disposed on the outer area 222 of the light incident surface 22 . That is to say, the second prism group 202 is not provided in the middle region 221 of the light incident surface 22 . Preferably, the optical lens 20 may also be provided with a mounting groove 23 at the position where the middle region 221 of the light incident surface 22 is located, and the mounting groove 23 is formed from the middle region 221 of the light incident surface 22 Extending toward the middle region 211 of the light-emitting surface 21, and the installation groove 23 also allows the light source 10 to be installed in it, in this way, the light generated by the light source 10 will first radiate to the The middle region 211 of the light emitting surface 21 .

As shown in FIGS. 11 and 12 , the light source 10 can generate light after being electrically connected to an external power source, and the light will then radiate from the middle region 221 of the light incident surface 22 into the interior of the optical lens 20 , When the light passes through the first prism group 201 arranged in the middle area 211 of the light-emitting surface 21, it will be automatically divided into the first part of the ray and the second prism group 201 by the first prism group 201. Two parts of the light, the first part of the light and the second part of the light will be processed by the optical lens 20 respectively from the middle area 211 and the outer area 212 of the light-emitting surface 21 of the optical lens 20 Radiation to the external environment of the anti-glare lamp.

It is worth mentioning that the first prism group 201 may be a compound eye prism group, and the compound eye prism group 201 includes a refraction part and a reflection part, and the refraction part and the reflection part are spaced apart and Evenly arranged, wherein when the light radiates to the refraction part of the compound eye prism group 201, it will be refracted by the refraction part to change the radiation path of the light, and from the middle region 211 of the light exit surface 21 Radiating to the external environment of the anti-glare lamp, this part of the light is the first part of the light defined by the present invention. When the light radiates to the reflective part of the compound eye prism group 201, it will be reflected by the reflective part to change the radiation path of the light, and this part of the light is not radiated from the light exit surface 21 to the anti-glare The external environment of the lamp is radiated to the second prism group 202, and this part of the light is the second part of the light defined by the present invention. In this way, the amount of light radiated through the middle region 211 of the light-emitting surface 21 of the optical lens 20 can be reduced, thereby reducing the central light intensity of the anti-glare lamp, thereby ensuring the anti-glare Eye-catching lamps will not appear dazzling.

The second part of the light is reflected by the first prism group 201 to change the radiation path and radiate to the second prism group 202, when the second part of the light radiates back to the second prism group 202 will continue to be refracted by the second prism group 202 to radiate from the outer area of the light-emitting surface 21 to the external environment of the anti-glare lamp. The light radiated from the central area 211 of the light emitting surface 21 is too concentrated to cause glare. On the other hand, the light emitting area of the optical lens 20 can be increased to improve the lighting effect of the anti-glare lamp.

It is worth mentioning that the second prism group 202 may only provide the capability of refracting light to change the radiation path of the light. When the light generated by the light source 10 passes through the second prism group 202, the second prism group 202 will change the outgoing angle of the light so as to change the radiation path of the light. Preferably, the outer region 222 of the light-incident surface 22 of the optical lens 20 extends curvedly, so that the second prism group 202 disposed on the outer region of the light-incident surface 22 is curved. extended. Specifically, the second prism set 202 may include a first area and a second area, the first area is set inside the second prism set 202, and the second area is set inside the second prism set 202. Outside the second prism group 202, the second region extends continuously and curvedly from the first region, and the second region and the first region have opposite extension curvatures. When the light is reflected by the first prism group 201 to change the radiation path and radiates to the second prism group 202, the light will first radiate to the first area of the second prism group 202, and be The first area refracts to change the radiation path and radiates to the second area of the second prism group 202, and is refracted by the second area to change the radiation path and radiates from the light emitting surface 21 to the second area. The outer zone 212 radiates to the outside environment of the anti-glare luminaire.

That is to say, the first part of the light generated by the light source 10 will be refracted by the first prism group 201 to radiate from the middle area 211 of the light emitting surface 21 to the anti-glare lamp. In the external environment, the second part of the light will be reflected by the first prism group 201, and refracted multiple times by the second prism group 202 to pass through the outer area 212 of the light-emitting surface 21 Radiating to the external environment of the anti-glare lamp, in such a way that the light generated by the light source 10 is radiated to the external environment of the anti-glare lamp after passing through the light-emitting surface 21 of the optical lens 20 more uniform, and will not form a dark area of light on the light emitting surface 21 of the optical lens 20, so as to improve the lighting effect of the anti-glare lamp.

As shown in FIG. 12 , the present invention will disclose in detail the working principle of the optical lens 20 when processing light in the following description.

When the light source 10 is electrically connected to an external power source, the light source 10 can generate light a and light b, and both light a and light b will be radiated to the first prism group 201 . The light a will be radiated to the refraction part of the first prism group 201 to change the exit angle of the light a to adjust the radiation path of the light a, and the light a will pass from the middle area of the light exit surface 21 211 radiates to the external environment of the anti-glare lamp. In this way, light a can be prevented from being concentratedly radiated from the middle area 211 of the light-emitting surface 21 to the external environment of the anti-glare lamp. To reduce the light intensity of the anti-glare lamp at the center, so as to achieve the anti-glare effect. It can be easily understood that when the light a is farther away from the central area of the first prism group 201 , the outgoing angle of the light a is changed more. The light b will be radiated to the reflection part of the first prism group 201 to change the exit angle of the light b to adjust the radiation path of the light b, and at this time the light b will be radiated to the second prism group 202, to be refracted by the second prism group 202 in the first region of the second prism group 202, and adjust the radiation path of light b again, at this time, light b will be radiated to the second region of the second prism group 202, so as to be refracted by the second prism group 202 in the second region of the second prism group 202, and adjust the light again The radiation path of b, at this time, light b will radiate from the outer area 212 of the light-emitting surface 21 to the external environment of the anti-glare lamp.

It is worth mentioning that by adjusting the radians of the light emitting surface 21 and the light incident surface 22 of the optical lens 20 , the light emitting angle of the light generated by the light source 10 can be adjusted within a certain range. For example, in the case of the same power and light effect, the smaller the light emitting angle of the anti-glare lamp, the stronger the light intensity of the anti-glare lamp, so that the brightness of the anti-glare lamp is brighter. It is adapted to be adjusted and designed according to the needs of the user.

As shown in Figure 13, the present invention also provides a method 1300 for preventing the glare effect of an anti-glare lamp, wherein the anti-glare method 1300 includes the following steps:

Step 1310: (a) refract a first part of the light rays radiated through the middle part of the anti-glare lamp, so that the first part of the light is radiated to the anti-glare lamp at the middle part of the anti-glare lamp The external environment of the lamp;

Step 1320: (b) reflect a second part of the light rays radiated through the middle part of the anti-glare lamp, so that the second part of the light radiates from the middle part of the anti-glare lamp to the surrounding part; as well as

Step 1330: (c) refract the second part of the light at the surrounding part of the anti-glare lamp, so that the second part of the light radiates to the anti-glare lamp at the surrounding part of the anti-glare lamp external environment.

Further, in the step (a), when the light passes through a first prism group 201 arranged in the radiation path of the light, it is automatically divided into the first part of the light and the second part of the light. Preferably, the first prism group 201 can be implemented as a compound-eye prism group 201, wherein the compound-eye prism group includes a refraction portion and a reflection portion, the refraction portion and the reflection portion are spaced apart and Evenly arranged, when the light passes through the refraction part, the outgoing angle of the light is changed to adjust the radiation direction of the light, and when the light passes through the reflection part, the light is reflected to adjust the radiation direction of the light.
