Description

Technical Field

[0001] The utility model belongs to the technical field of lamp equipment, and particularly relates to a diffuse reflection lamp panel. Background Art

[0002] Traditional diffuse reflection lamps are mostly extruded multi-piece LED lamp bodies. The diffuse reflection effect is achieved by inverting the light source at the bottom of the diffuse reflection lamp and reflecting the light emitted by the light source multiple times through the arc-shaped reflection cavity formed by the reflection wall, such as a diffuse reflection lamp disclosed in the Chinese utility model patent with announcement number CN205716505U.

[0003] However, in actual use, it was found that the lamp still has some shortcomings, that is, the light source is simply placed on the aluminum substrate, so the protection level of the lamp does not meet the design requirements of IP65; and although the lamp omits the traditional light guide plate and diffuser to increase the total luminous flux, and the light source is diffusely reflected under the effect of the reflective wall, making the light softer and reducing the user's dizziness. However, it is precisely because of the omission of the light guide plate and diffuser that the brightness of the position of the reflective wall close to the light source is significantly higher than that of other positions. The actual test light efficiency can only be maintained at about 80. Compared with products that emit light directly from the front instead of diffuse reflection from the side, the light efficiency is greatly reduced, which affects the overall visual effect and cannot meet the customer indicators of high light flux and high light efficiency. In the technical selection, the structure has no advantage and is difficult to be more universal. If the user uses the lamp for a long time, it will cause unnecessary damage to the eyes.

[0039] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0040] The most critical concept of the present invention is that after the light source device is fixed inside the light source slot, the limit plate can provide structural support for the subsequent further fixing of the light guide plate and / or the diffuser plate, and because the light source device is matched with the light guide plate or the diffuser plate, the overall visual effect will be softer, but the total luminous flux will also be affected to a certain extent; therefore, the reflective fill light effect of the fill light plate is used to ensure that the total luminous flux can meet the design requirements.

[0041] Please refer to Figures 1 to 3 The diffuse reflection lamp panel provided by the utility model comprises a reflection arc surface 1, and light source grooves 2 respectively arranged at two ends of the bending direction of the reflection arc surface 1;

[0042] A limit plate 3 is provided at the connection between the light source slot 2 and the reflective arc surface 1;

[0043] A fill light plate 4 is provided on the side of the light source slot 2 opposite to the limiting plate 3;

[0044] The notch of the light source slot 2 and the fill-in light surface 41 of the fill-in light plate 4 are both arranged toward the concave surface of the reflective arc surface 1;

[0045] The free end of the limiting plate 3 is arranged toward the bottom of the light source slot 2 .

[0046] Specifically, the axis of the light source slot 2 and the axis of the reflective arc surface 1 are parallel to each other.

[0047] From the above description, it can be seen that the beneficial effects of the utility model are: providing a diffuse reflection lamp panel, when the light source device is fixed inside the light source slot 2, the limit plate 3 can provide structural support for the subsequent further fixing of the light guide plate and / or the diffuser plate, and because the light source device is matched with the light guide plate or the diffuser plate, the overall visual effect will be softer, but the total luminous flux will also be affected to a certain extent; therefore, through the reflective fill light effect of the fill light plate 4, it is ensured that the total luminous flux can meet the design requirements; compared with the existing diffuse reflection lamp panel, it can take into account both the lighting effect and the luminous flux requirements, thereby improving the visual effect while also being able to protect the user's eyes to a certain extent.

[0048] Further, the light source slot 2 is a U-shaped slot;

[0049] One side wall of the light source slot 2 is connected to either end of the reflection arc surface 1 in the bending direction, and the limiting plate 3 is arranged at the connection between one side wall of the light source slot 2 and the reflection arc surface 1;

[0050] A fill light plate 4 is provided at one end of the other side wall of the light source slot 2 away from the slot bottom of the light source slot 2;

[0051] The limiting plate 3 , the light source slot 2 and the fill light plate 4 are all located within the vertical projection range of the reflective arc surface 1 .

[0052] From the above description, it can be seen that the design has made specific improvements to the structure of the light source slot 2, as well as the layout between the limiting plate 3, the fill light plate 4 and the light source slot 2, so that the relevant light source equipment can be better fixed in the light source slot 2 and ensure that the overall lighting effect can meet the design requirements.

[0053] Furthermore, the included angle between the fill light plate 4 and the side wall of the light source slot 2 is an obtuse angle;

[0054] The opening of the included angle is arranged toward the outside of the light source slot 2 .

[0055] From the above description, it can be seen that the design has made a specific optimization of the direction of the fill light plate 4, so that a part of the light emitted by the light source device cannot be irradiated on the reflective arc surface 1, and can change the path under the action of the fill light plate 4, thereby gathering the light and making all the light hit the reflective arc surface 1, thereby improving the overall luminous flux.

[0056] Furthermore, the diffuse reflection lamp panel further includes a light source assembly 5;

[0057] The light source assembly 5 includes a heat dissipation slot 51, an aluminum substrate 52, a light source component 53, a silicone plug 54 and a transparent adhesive layer;

[0058] The heat dissipation groove 51 is a U-shaped groove;

[0059] Along the direction from the bottom of the heat dissipation slot 51 to the slot opening, an aluminum substrate 52, a light source component 53 and a transparent adhesive layer are sequentially stacked on the bottom of the heat dissipation slot 51;

[0060] Silicone plugs 54 are arranged at both ends of the heat dissipation slot 51 in the length direction, and the silicone plugs 54 are interference fit with the side wall of the heat dissipation slot 51. Specifically, in some occasions where the protection level is not high, the light source component 53 can be directly placed at the bottom of the light source slot 2, and then the limiting plate 3 and the light guide plate and / or the diffuser plate can be matched to achieve a quick assembly effect. The protection level of this assembly method can reach IP20.

[0061] From the above description, it can be seen that the design has made specific improvements to the structure of the light source assembly 5, and the protection level of the light source assembly 5 is improved by improving the structure of the light source assembly 5, thereby indirectly improving the protection level of the diffuse reflection lamp panel, that is, after the aluminum substrate 52 and the light source component 53 are placed at the bottom of the heat dissipation groove 51, silicone plugs 54 that are interference fit with the side walls of the heat dissipation groove 51 are set at both ends of the heat dissipation groove 51 in the length direction, and then in the process of pouring transparent glue to form a transparent glue layer, it is possible to prevent the transparent glue from leaking from the two ends of the heat dissipation groove 51 in the length direction. Through this design, the light source component 53 can be better protected inside the transparent glue layer, so the purpose of improving the protection level of the light source assembly 5 can be achieved.

[0062] Furthermore, the height of the side wall of the heat dissipation slot 51 close to the fill light plate 4 is greater than the height of the side wall of the heat dissipation slot 51 away from the fill light plate 4 .

[0063] From the above description, it can be seen that the design reduces the height of the side wall of the heat dissipation groove 51 close to the fill light plate 4, so that the light can be better irradiated on the fill light surface 41 of the fill light plate 4, so that this part of the escaped light can be smoothly hit on the reflective arc surface 1 under the gathering of the fill light plate 4, thereby effectively improving the overall luminous flux.

[0064] Furthermore, a heat dissipation frame 6 is provided on the outer side of the reflective arc surface 1;

[0065] The reflective arc surface 1, the light source slot 2 and the heat dissipation frame 6 are an integrated structure.

[0066] From the above description, it can be seen that after working for a long time, the reflective arc surface 1 and the light source groove 2 are prone to increase in temperature due to the heat emitted by the light source. By setting up the heat dissipation frame 6, the heat can be effectively absorbed and dissipated, thereby avoiding affecting the use effect of the lamp due to the temperature rise and increasing the risk of fire hazards.

[0067] Furthermore, the diffuse reflection lamp panel further comprises an end cover 7;

[0068] The end caps 7 are arranged at both ends of the reflecting arc surface 1 in the length direction;

[0069] The end cover 7 is detachably connected to the heat dissipation frame 6 .

[0070] From the above description, it can be seen that the design enables the staff to reasonably set the number of diffuse reflection lamp panels according to actual lighting needs. That is, when only one diffuse reflection lamp panel is required for lighting, after the diffuse reflection lamp panel is fixed, by setting end covers 7 at both ends of the diffuse reflection lamp panel, the internal light source assembly 5 can be effectively protected; if multiple diffuse reflection lamp panels are required for lighting, it is only necessary to remove the end covers 7 between each diffuse reflection lamp panel, and connect multiple diffuse reflection lamp panels by end docking, so as to increase the length of the diffuse reflection lamp panel, and finally, connect the ends of the two outermost diffuse reflection lamp panels of the end cover 7 to efficiently complete the overall installation work, thereby indirectly improving the overall flexibility of use.

[0071] The diffuse reflection lamp panel of the utility model can be used for daily lighting work, and is particularly suitable for panel lights that need to be installed continuously in subways, high-speed railways, etc., or public places that need to achieve artistic shapes indoors and outdoors.
