Description

Technical Field

[0001] This application relates to the field of lighting equipment technology, and specifically to a luminaire with a transparent anti-glare double lens structure. Background Technology

[0002] Traditional LED bulbs use transparent or milky-white lampshades. Transparent lampshades allow light to pass through, meaning the emitting LED beads are directly visible to the human eye during operation. The light from these beads can easily irritate the eyes and cause eye strain. To address this issue, bulbs with milky-white lampshades have emerged. Milky-white lampshades diffuse light more softly and evenly, preventing harsh glare and offering some protection to the eyes. However, compared to transparent lampshades, milky-white lampshades are opaque. Light lingers on the milky-white surface, resulting in greater light loss and glare. Therefore, milky-white lampshades reduce the amount of light emitted by the bulb, lowering the illumination of objects. Summary of the Invention

[0003] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a lamp that can both make the light diffuse more softly and evenly into space, achieving an anti-glare effect, and avoid affecting brightness. The technical solution adopted includes:

[0004] A lamp with a transparent anti-glare dual-lens structure includes a housing with a light-emitting cavity and a lamp plate, a first transparent lens, and a second transparent lens arranged sequentially inside the housing. The side of the first transparent lens and the second transparent lens closest to the lamp plate is the light-incident surface, and the other side is the light-emitting surface. The light-emitting surfaces of the first transparent lens and the second transparent lens are respectively provided with transparent prism microlens arrays, and the prism microlenses on the first transparent lens and the second transparent lens have different shapes.

[0005] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: it further includes a reflector cup, which is disposed inside the housing and distributed between the lamp plate and the first transparent lens.

[0006] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: the light-incident surface of the first transparent lens and / or the light-incident surface of the second transparent lens are provided with a Fresnel structure, a fly-eye transparent lens structure or a compound-eye transparent lens structure.

[0007] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: a Hartmann array is also provided on the light incident surface of the second transparent lens.

[0008] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: the transparent prism microlens is square, rhomboid, circular, polygonal or elliptical in shape.

[0009] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: the first transparent lens and the second transparent lens are made of transparent plastic, transparent soft rubber or transparent glass.

[0010] The beneficial effects of this utility model are:

[0011] Light emitted from the LEDs on the lamp panel enters the prismatic microlens array of the first transparent lens, undergoes multiple reflections and refractions, generates optical path oscillations, and changes the direction of the light before exiting to the second transparent lens. The light emitted from the light-transmitting plate of the second transparent lens undergoes multiple reflections and refractions again, generating optical path oscillations, changing direction, and exiting. The surface microstructure design disperses the light. Different shapes of prismatic microlens arrays produce different light effects after reflection and refraction of the beam. Therefore, by utilizing the synergistic effect of the prismatic microlenses on the first and second transparent lenses, the uniformity of the emitted light is ensured, preventing high-intensity direct glare and preventing the LEDs from being directly observed by the naked eye outside the lamp, thus achieving anti-glare. Total internal reflection by the first and second transparent lenses reduces light loss and ensures brightness.

[0012] The phase gradient of the prism microlens can directionally deflect the sub-beam, for example, to concentrate the light onto a specific area, thereby reducing ineffective scattered light while ensuring brightness; furthermore, by adjusting the shape design of the first and second transparent lenses, the light emission angle of the lamp with the transparent anti-glare dual-lens structure can be adjusted within the range of 10°-90°.

[0020] Reference Figure 1 This application proposes an embodiment of a lamp with a transparent anti-glare dual-lens structure, characterized in that it includes a housing 10 with a light-emitting cavity and a lamp plate 20, a first transparent lens 30, and a second transparent lens 40 arranged sequentially inside the housing 10. The first transparent lens 30 and the second transparent lens 40 have a light-incident surface on the side near the lamp plate 20 and a light-emitting surface on the other side. The light-emitting surfaces of the first transparent lens 30 and the second transparent lens 40 are respectively provided with prism microlens arrays 50, and the prism microlenses on the first transparent lens 30 and the second transparent lens 40 have different shapes.

[0021] The light emitted by the LEDs on the lamp panel 20 is reflected and refracted multiple times by the prismatic microlens array 50 of the first transparent lens 30, causing optical path oscillation and changing the direction of the light before it is emitted to the second transparent lens 40. The light emitted to the light-transmitting plate of the second transparent lens 40 is reflected and refracted multiple times again, causing optical path oscillation and changing the direction of the light before it is emitted. The surface microstructure design disperses the light. Different shapes of prismatic microlens arrays 50 produce different light effects after reflecting and refracting the light beam. By utilizing the synergistic effect of the prismatic microlenses on the first transparent lens 30 and the second transparent lens 40 on the light beam, the uniformity of the emitted light is ensured, high-intensity direct glare is avoided, and the luminous LEDs are not directly visible to the naked eye outside the lamp, thus achieving anti-glare. The total internal reflection of the first transparent lens 30 and the second transparent lens 40 reduces light loss and ensures brightness.

[0022] The phase gradient of the prism microlens can directionally deflect the sub-beam, for example, to concentrate the light onto a specific area, thereby reducing ineffective scattered light while ensuring brightness; furthermore, by adjusting the shape design of the first transparent lens 30 and the second transparent lens 40, the light emission angle of the lamp with the transparent anti-glare dual lens structure can be adjusted within the range of 10-90°.

[0023] The luminaire with a transparent anti-glare double lens structure described in this application can be applied to bulb lamps, improving the brightness of the bulb lamp while achieving anti-glare. In addition, it can also be applied to UFO lamps, such as... Figure 1 and 2 As shown, it can also be applied to lighting fixtures that require high light intensity at specific angles, such as wall lamps, mirror lights, office lights, home lights, strip lights, commercial engineering lights, and outdoor tri-proof lights.

[0024] Preferably, this application provides a reflector cup 60 between the lamp panel 20 and the first transparent lens 30. The light emitted by the lamp beads on the lamp panel 20 within a certain range is reflected by the reflector cup 60 to concentrate the scattered light emitted by the array of lamp beads, forming a more directional beam, reducing light divergence, and helping to improve light intensity and illumination distance. Moreover, when designing the light output range of the lamp, the diffusion angle of the beam can be changed by adjusting the curvature and depth of the reflector cup 60, thereby achieving the adjustment of the light output range of the lamp from narrow to wide.

[0025] The light-incident surface of the first transparent lens 30 and / or the light-incident surface of the second transparent lens 40 may also be provided with a Fresnel structure 70, a fly-eye transparent lens structure, or a compound-eye transparent lens structure.

[0026] After the light shines on the reflector cup 60, it is collimated and shines on the first transparent lens 30. Based on this, as a preferred embodiment, a Fresnel structure 70, a fly-eye lens, or a compound-eye lens can also be provided on the light-incident surface of the first transparent lens 30 and / or the light-incident surface of the second transparent lens 40. The Fresnel structure 70, the fly-eye transparent lens structure, or the compound-eye transparent lens structure can focus the light, which is beneficial to improving the illumination brightness.

[0027] In this embodiment, the light-incident surface of the first transparent lens 30 is provided with a Fresnel structure 70, such as... Figure 2 As shown, with the Fresnel structure 70 provided on the light-incident surface of the first transparent lens 30, a Hartmann array 80 can also be provided on the light-incident surface of the second transparent lens 40. This prevents the light emitted by the lamp panel from being too divergent, which would cause the Hartmann array 80 to malfunction. The Fresnel structure 70 collimates the light from the bulb to form parallel light. After the parallel light shines on the Hartmann array 80 provided on the light-incident surface of the second transparent lens 40, the Hartmann array 80 splits the light beam through microlenses, decomposing the light with a large divergence angle into multiple sub-beams. It then focuses the light to form a regular light spot array, further homogenizing the light intensity distribution. The light beam is then oscillated by the prism microlens on the light-out surface of the second transparent lens 40 and directionally deflected before being emitted, achieving light emission within the range of 10°-90° and reducing uneven brightness.

[0028] This application does not specifically limit the material of the first transparent lens 30 and the second transparent lens 40; they can be transparent plastic, transparent soft rubber, or transparent glass.

[0029] In this application, the shape of the prism microlens is square, rhomboid, circular, polygonal, or elliptical. In order to achieve different light effects, the shape of the prism microlens can be adjusted. For example, a hexagonal microlens can achieve uniform light and expand the illumination angle, a square microlens can control the diffusion angle of the lamp in the horizontal or vertical direction, and a circular microlens can form a soft circular light spot.

[0030] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
