Description

Technical Field

[0001] The utility model belongs to the technical field of lighting fixtures, and more specifically, relates to a downlight with a night mode. Background Art

[0002] Downlights are a type of lighting fixture embedded in the ceiling that emits light downwards. Their greatest feature is that they can maintain the overall unity and perfection of architectural decoration, and will not destroy the perfect unity of the ceiling art due to the setting of the lamp. This type of hidden lamp embedded in the ceiling projects all light downwards, which is a direct light distribution. Downlights do not take up space and can add a soft atmosphere to the space, so they are widely used in various places.

[0003] Night lights are tools used for automatic lighting in dim environments, which provide great convenience for people's nighttime activities. Since the light of downlights is projected directly downward, the light intensity is relatively high and cannot be used directly as night lights. Therefore, in order to meet different usage needs, users often need to install downlights and night lights at the same time, which greatly occupies indoor space and is inconvenient to use.

[0004] In the prior art, some downlights are integrated with night light modules, which are arranged around the main light source and separated from the main light source by a reflective cup. A gap is left between the reflective cup and the outer shell, and a light guide ring is arranged in the gap to guide the light generated by the night light source to the outside. However, due to the small luminous area of ​​the light guide ring, the light cannot be fully scattered outward, resulting in poor light transmission effect of the night light mode and insufficient lighting brightness. However, if the brightness of the night light source is increased, the light will be concentrated, which will irritate the eyes and affect the user's rest, which is not in line with the original intention of the night light mode design. Utility Model Content

[0005] The purpose of the utility model is to provide a downlight with a night mode, aiming to solve the problem in the prior art that the downlight in the night light mode has poor light transmittance resulting in insufficient lighting brightness and irradiation area, but after increasing the brightness of the night light source, the light is concentrated, affecting the user's rest.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] In a first aspect, a downlight with a night mode is provided, comprising:

[0008] lampshade;

[0009] A light-emitting module is disposed in the lampshade, and the light-emitting module comprises a main light source and an auxiliary light source disposed around the main light source;

[0010] A reflective cup is disposed in the lampshade and abuts against the light-emitting module, the reflective cup separates the main light source from the auxiliary light source and is used to reflect the light emitted by the main light source;

[0011] A light guide module is sleeved outside the reflective cup, the light guide module includes a plurality of light guide rings sequentially distributed from the inside to the outside, and the plurality of light guide rings are used to project the light of the auxiliary light source outward; and

[0012] The light-shielding ring is arranged between two adjacent light-guiding rings.

[0013] In a possible implementation, the light guide ring includes a connection area and a dispersion area distributed from top to bottom, and the dispersion area is bent toward the outside of the connection area, so that the light guide ring forms a conical structure with a diameter gradually increasing from top to bottom.

[0014] In a possible implementation, two adjacent connection areas are in contact with each other, a spacing space is formed between two adjacent dispersion areas along the radial direction, and the light shielding ring is disposed in the spacing space.

[0015] In a possible implementation, a plurality of light-scattering grooves are formed on an outer peripheral surface of the dispersion zone.

[0016] In a possible implementation, the downlight with night mode further includes a first sealing ring disposed between two adjacent light guide rings and a second sealing ring disposed between the light guide ring and the reflective cup.

[0017] In a possible implementation, a first installation groove is formed on the outer circumferential surface of the light guide ring along the circumferential direction, and the first sealing ring is embedded in the first installation groove.

[0018] In a possible implementation manner, a second installation groove is formed on the outer circumferential surface of the reflective cup along the circumferential direction, and the second sealing ring is embedded in the second installation groove.

[0019] In a possible implementation, the downlight with night mode further includes a sealing gasket, which is disposed between the outermost light guide ring and the lampshade and is used to seal a gap between the lampshade and the outermost light guide ring.

[0020] In a possible implementation, a receiving groove is formed on the inner circumferential surface of the reflective cup, and the downlight with night mode further includes a diffusion plate installed in the receiving groove.

[0021] In a possible implementation manner, a sealant is further provided in the receiving groove, and the sealant fixes the diffuser plate and the reflective cup.

[0022] The beneficial effect of the downlight with night mode provided by the utility model is that: compared with the prior art, the downlight with night mode provided by the utility model is provided with a plurality of light guide rings on the outside of the reflective cup, and the light emitted by the auxiliary light source is jointly guided out by the plurality of light guide rings, which increases the light emitting area, so that the area covered by the light after being projected outward is wider, thereby increasing the irradiation range of the light. The light shielding ring can prevent the problem of excessive brightness of the light caused by the light being projected outward through the plate surface (thickness direction) of the light guide ring, so that the light can only be projected outward along the longitudinal cross-sectional direction of the light guide ring. In addition, since the light emitting area is increased, the external projection rate of the light is improved, so that the brightness of the light projected to the outside is correspondingly increased without changing the light intensity of the auxiliary light source, and at the same time, it is avoided that the light concentration causes irritation to the user's eyes and avoids affecting the user's rest.

In the claims, specification and the above drawings of the present utility model, the terms "including", "having" and their variations are used, and the intention is to "include but not limited to".

[0032] Please also read Figures 1 to 5 Now, the downlight with night mode provided by the utility model is described. The downlight with night mode includes a lampshade 2, a light-emitting module 3, a reflective cup 8, a light-guiding module and a light-shielding ring 7; the light-emitting module 3 is arranged in the lampshade 2, and the light-emitting module 3 includes a main light source 301 and an auxiliary light source 302 arranged around the outer periphery of the main light source 301; the reflective cup 8 is arranged in the lampshade 2 and abuts against the light-emitting module 3, and the reflective cup 8 separates the main light source 301 from the auxiliary light source 302, and is used to reflect the light emitted by the main light source 301; the light-guiding module is sleeved outside the reflective cup 8, and the light-guiding module includes a plurality of light-guiding rings 6 distributed in sequence from the inside to the outside, and the plurality of light-guiding rings 6 are used to project the light of the auxiliary light source 302 to the outside; the light-shielding ring 7 is arranged between two adjacent light-guiding rings 6.

[0033] Compared with the prior art, the utility model provides a downlight with a night mode. The utility model has a plurality of light guide rings 6 disposed on the outside of a reflective cup 8. The light emitted by the auxiliary light source 302 is jointly guided by the plurality of light guide rings 6, which increases the light emitting area, so that the area covered by the light after being projected outward is wider, thereby increasing the irradiation range of the light. The light shielding ring 7 can prevent the problem of excessive brightness of the light caused by the light being projected outward through the plate surface (thickness direction) of the light guide ring 6, so that the light can only be projected outward along the longitudinal cross-sectional direction of the light guide ring 6. In addition, since the light emitting area is increased, the external projection rate of the light is increased, so that the brightness of the light projected to the outside is correspondingly increased without changing the light intensity of the auxiliary light source 302, while avoiding the stimulation of the user's eyes caused by the concentration of light, thereby avoiding affecting the user's rest.

[0034] It should be noted that, during normal use, the main light source 301 works, and the light generated by the main light source 301 is reflected by the reflective cup and concentratedly projected downward, thereby increasing the brightness of the light projection. When using the night light mode, the light generated by the auxiliary light source 302 enters from the top of the multiple light guide rings 6, and is projected outward from the bottom along the extension path of the light guide rings 6. The light is lost during transmission within the light guide rings 6, thereby avoiding excessive brightness of the light. In addition, since the present application uses multiple light guide rings 6 to project light outward, the projection area of ​​the light can be increased, and although the brightness of the light after being projected by multiple light guide rings 6 is greater than that of the light projected by a single light guide ring 6, the bottom ends of the multiple light guide rings 6 have radial spacing, thereby avoiding the excessive brightness caused by the concentration of light that affects the user's rest.

[0035] In some embodiments, see Figures 1 to 5 The light guide ring 6 includes a connection area 601 and a dispersion area 602 distributed from top to bottom. The dispersion area 602 is bent toward the outside of the connection area 601, so that the light guide ring 6 forms a cone-shaped structure with a diameter gradually increasing from top to bottom.

[0036] The light guide ring 6 in this embodiment adopts a conical structure, and the dispersion area 602 increases the light guide area, so that the coverage area of ​​the light projection is wider. The end of the connection area 601 is located below the auxiliary light source 302, and is used to receive the light projected by the auxiliary light source 302. At the same time, the adjacent connection area 601 brackets are connected to each other, and the innermost connection area 601 is also connected to the reflective cup 8 to fix the light guide module.

[0037] In some embodiments, see Figures 1 to 5 The two adjacent connection areas 601 are in contact with each other, and a spacing space is formed between the two adjacent dispersion areas 602 along the radial direction, and the light shielding ring 7 is arranged in the spacing space.

[0038] The connection areas 601 fit each other, and multiple light guide rings 6 can be connected as a whole, effectively receiving the light emitted by the auxiliary light, and preventing the light from being projected outward from the gap between two adjacent light guide rings 6. Two adjacent dispersion areas 602 form a spacing space in the radial direction, thereby reducing or avoiding the overlapping area of ​​the light projected from two adjacent light guide rings 6, avoiding the problem of excessive brightness caused by light concentration, and also increasing the coverage area of ​​the light, which can increase the indoor lighting area.

[0039] In some embodiments, see Figures 1 to 5 A plurality of light scattering grooves 603 are provided on the outer peripheral surface of the dispersion area 602 .

[0040] After the light passes through the dispersion area 602, the light is scattered due to the arrangement of the diffusion grooves 603, so that the projection direction of the light is more dispersed, thereby achieving a soft light emission effect.

[0041] Optionally, the astigmatism grooves 603 are sequentially arranged at intervals around the circumference of the dispersion area 602 to form the astigmatism area 602, and a plurality of astigmatism areas 602 are arranged along the circumference.

[0042] Optionally, the astigmatism groove 603 has a circular groove body.

[0043] In some embodiments, see Figures 1 to 5 The downlight with night mode further includes a first sealing ring 4 arranged between two adjacent light guide rings 6 and a second sealing ring 5 arranged between the light guide ring 6 and the reflective cup 8.

[0044] The first sealing ring 4 can improve the sealing performance between two adjacent light guide rings 6, prevent light from being projected outward from the gap between the two adjacent light guide rings 6, and also prevent external moisture and dust from entering the interior of the lamp body. The second sealing ring 5 seals the gap between the light guide ring 6 and the reflective cup 8, prevents external moisture and dust from entering the interior of the lamp body, and improves the overall sealing effect of the lamp.

[0045] Optionally, the first sealing ring 4 and the second sealing ring 5 are both flexible components, such as rubber or silicone components.

[0046] In some embodiments, see Figures 1 to 5 A first mounting groove 6021 is formed on the outer peripheral surface of the light guide ring 6 along the circumferential direction, and the first sealing ring 4 is embedded in the first mounting groove 6021 .

[0047] The first sealing ring 4 is embedded in the first installation groove 6021, and the exposed portion of the first sealing ring 4 is squeezed and sealed with the adjacent light guide ring 6 to seal the space between the two adjacent light guide rings 6. The solution in this embodiment increases the firmness and stability of the installation of the first sealing ring 4, and compared with the installation method of filling and bonding, the solution in this embodiment is not affected by humidity and temperature.

[0048] In some embodiments, see Figures 1 to 5 A second mounting groove 801 is formed on the outer peripheral surface of the reflective cup 8 along the circumferential direction, and the second sealing ring 5 is embedded in the second mounting groove 801 .

[0049] The second sealing ring 5 is embedded in the second installation groove 801, and the exposed part of the second sealing ring 5 is squeezed and sealed with the light guide ring 6, so as to seal the light guide ring 6 and the reflective cup 8. The solution in this embodiment increases the firmness and stability of the installation of the second sealing ring 5, and compared with the installation method of filling and bonding, the solution in this embodiment is not affected by humidity and temperature.

[0050] In some embodiments, see Figures 1 to 5 The downlight with night mode further comprises a sealing gasket 1 , which is arranged between the outermost light guide ring 6 and the lampshade 2 and is used for sealing the gap between the lampshade 2 and the outermost light guide ring 6 .

[0051] The sealing gasket 1 blocks the gap between the lampshade 2 and the outer light guide ring 6 to prevent impurities such as moisture from entering the lamp body, thereby ensuring that the auxiliary light source 302 is in a clean environment. In addition, the sealing gasket 1 can also prevent light from being projected outward from the gap between the lampshade 2 and the light guide ring 6.

[0052] Optionally, the sealing gasket 1 is an EVA component, which has a certain elastic force and can block the risk between the light guide ring 6 and the lampshade 2 by extrusion sealing to avoid damage to the lampshade 2 or the light guide ring 6.

[0053] In some embodiments, see Figures 1 to 5 The inner circumference of the reflective cup 8 is provided with a receiving groove, and the downlight with night mode further includes a diffusion plate 9 installed in the receiving groove.

[0054] The diffusion plate 9 is fixed in the receiving groove by plugging, without using external connecting components, which is not only convenient for installation but also avoids the problem of damage to the diffusion plate 9 during drilling.

[0055] In some embodiments, see Figures 1 to 5 A sealant is also provided in the receiving groove, and the sealant fixes the diffusion plate 9 and the reflective cup 8.

[0056] The receiving groove is filled with sealant, which can increase the firmness of the connection between the diffuser plate 9 and the reflector cup 8 on the one hand, and improve the sealing effect on the other hand to prevent impurities such as moisture from entering the diffuser plate 9 and the reflector cup 8, thereby causing damage to the main light source 301.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
