[0026] Example:

[0027] like Figure 1-6As shown, in this embodiment, the lighting device includes: a suspension member 1 with an installation cavity and a lamp assembly 2 installed in the installation cavity, the lamp assembly 2 includes a plurality of light sources 21 arranged at intervals, and a polarization adjustment member 22 arranged corresponding to each light source 21, the polarization adjustment member 22 is used to perform polarization processing to eliminate glare generated by the light path; when the lighting device is working, the light emitted by each light source 21 passes through the corresponding polarization adjustment member 22 respectively, and finally reaches the target position of the bed area outside the installation cavity.

[0028] Specifically, the suspension member 1 can be a suspension bridge, and the installation cavity is formed on the suspension beam of the suspension bridge, and the opening of the installation cavity is located at the bottom side of the suspension beam of the suspension bridge. This deep-hidden assembly method is used to install the lamp assembly 2, which can achieve the "light is visible but not the lamp" lighting effect, and the fixed lamp does not need to be connected to the outward extending structure on the suspension beam, which is conducive to saving installation space, greatly improving the appearance of the suspension bridge product, and can effectively eliminate the glare generated in the area outside the bed surface; and the setting of the polarization adjustment member 22 can eliminate the glare generated in the lighting area. In this embodiment, multiple light sources 21 are set to ensure that the brightness of the light can meet the relevant requirements and ensure that the light can just evenly cover the entire bed area.

[0029] In this embodiment, the lamp assembly 2 also includes a lamp board 23, and each light source 21 is fixed between the lamp board 23 and the polarization adjustment member 22. And each light source 21 is fixed on one side of the lamp board 23, and the polarization adjustment member 22 is also located on the side of the lamp board 23 facing the light source 21. The polarization adjustment member 23 can make the light emitted by each light source 21 deviate from the preset angle and finally reach the target position of the bed area. Further, in some embodiments, the polarization adjustment member 22 includes a plurality of TIR lens monomers and a connecting portion 23 connected between adjacent TIR lens monomers, and the TIR lens monomers are arranged one by one with the light source 21, so that the light emitted by each light source 21 can directly reach the corresponding TIR lens monomer. The lamp board 23 and the connecting portion 224 can be provided with multiple installation positions to facilitate fixing the plurality of light sources 21 and the polarization adjustment member 22 as one. The plurality of light sources 21 and the polarization adjustment member 22 are integrated into a module through the lamp board 23, which is more convenient to be installed on the suspension bridge. In some embodiments, an anti-fool column 225 is also provided on the connection portion 224; specifically, two asymmetric anti-fool columns 225 can be provided at intervals on a connection portion 224 to prevent the assembly from being reversed. The TIR lens monomer, the connection portion 224, and the anti-fool column 225 can be obtained by integral injection molding. Preferably, a polarization adjustment member 22 can integrate six TIR lens monomers, and is arranged in a module composed of six light sources 21 and a polarization adjustment member 22. This can not only avoid the increase in assembly workload due to the small number of connected parts, but also avoid the occurrence of excessive warping deformation after demolding and the impact on the optical performance of the device. A lamp assembly 2 can be a single module as described above, or it can be composed of a light panel and a plurality of modules as described above. Preferably, three modules constitute a lamp assembly 2.

[0030] In this embodiment, the TIR lens monomer includes a main body 221 with a clearance groove 222 at the top, and a polarizing stripe 223 is provided at the bottom of the main body 221, and the light source 21 is located in the clearance groove 222. It can effectively constrain the light in the radial direction of the optical axis and eliminate the glare generated by the lateral lighting area of ​​the straight lens. Specifically, the polarizing stripe 223 can be a Fresnel stripe. In this way, the design method of using a TIR lens combined with a Fresnel stripe structure can constrain the large-angle light of the LED light source 21, and can make the light deviate by a specified angle to achieve the required lighting effect.

[0031] Furthermore, in this embodiment, multiple lamp assemblies 2 can be provided, and the angles between the light emitted by the light source 21 on different lamp assemblies 2 and the height direction are different. Preferably, two lamp assemblies 2 can be provided, one of which is used to illuminate the head area, and the angle between the light emitted by the light source 21 in this lamp assembly 2 and the height direction can be 0°~30°; the other lamp assembly 2 is used to illuminate the waist area, and the angle between the light emitted by the light source 21 in this lamp assembly 2 and the height direction can be 30°~55°; the cooperation between the two lamp assemblies 2 can just allow the light to form a complete coverage of the area corresponding to the target bed.

[0032] Specifically, when setting up lighting devices for hospital beds, the corresponding light source design requirements can be simulated based on the usage requirements and the general height of hospital beds. Figure 1 As shown, the lamps are usually installed at the bottom of the suspension bridge beam. The distance from the bottom of the suspension bridge beam to the bed surface is about 1500mm. The maximum angle between the light in the longitudinal target lighting area and the fixed direction is about 55°. It can be divided into two areas: ① Head area: the angle between the light and the height direction is 0°~30°, ② Waist area: the angle between the light and the height direction is 30°~55°; this can avoid interference with the adjacent beds at night, and the horizontal lighting area can be controlled between 1000~2000mm.

[0033] In this embodiment, an adjustment component 3 and a fixing member 4 are also provided in the installation cavity. The fixing member 4 is fixed between the installation cavity and the adjustment component 3, and the adjustment component 3 is connected to the lamp assembly 2. The adjustment component 3 is used to adjust the illumination angle of the lamp assembly 2. The suspension bridge beam and the fixing member 4 can be firmly fixed together by a threaded component, etc., to ensure the structural stability of the lighting device. The assembly angle of the lamp assembly 2 can be adjusted by the adjustment component 3, so that the lighting areas of the two lamp assemblies 2 can be perfectly transitioned together.

[0034] In this embodiment, the fixing member 4 is provided with a mounting hole and a waist-shaped hole 41, and the adjustment assembly 3 includes a connecting plate 31 fixed to the lamp board 23, a first nut 32 connected between the connecting plate 31 and the mounting hole, and a second nut 33 connected between the connecting plate 31 and the waist-shaped hole 41. The connecting plate 31 can be a U-shaped plate, the middle part of the connecting plate 31 is fixed to the side of the lamp board 23 away from the polarization adjustment member 22, the two ends of the connecting plate 31 are located at the two ends of the lamp board 23, and the two ends of the connecting plate 31 are connected to the fixing member 4 through the first nut 32 and the second nut 33 respectively. The first nut 32 can be used as a fulcrum; there is a certain clearance space on the waist-shaped hole 41, and the angle adjustment of the connecting plate 31 and the entire lamp assembly 2 can be achieved by adjusting the relative position of the second nut 33 and the waist-shaped hole 41, which has a simple structure and easy assembly operation. Specifically, the fixing member 4 may include a sheet metal member with a mounting hole and a waist-shaped hole 41 and a connecting member connecting the sheet metal member and the suspension member 1 . The connecting member may be connected to the suspension member 1 in the mounting cavity by threaded fastening.

[0035] In this embodiment, the upper side of the lamp board 23 (the side of the lamp board 23 facing away from the light source 21) is also connected to a module heat sink 5, which can help the lamp assembly 2 dissipate heat, avoid the lamp assembly 2 from being overheated, and improve the safety performance of the entire lighting device. Further, in some specific embodiments, the module heat sink 5 includes a main board and a plurality of heat sinks vertically connected to the main board. The heat sinks are spaced apart from each other, have high heat transfer efficiency, and a large heat dissipation area. The heat generated by the lamp assembly 2 can be quickly transferred to the air through the main board and each heat sink, and the heat dissipation effect is good. Assembly holes can be respectively provided on the module heat sink 5, the connecting plate 31, the lamp board 23, and the polarization adjustment member 22. During assembly, the pins between the module heat sink 5, the connecting plate 31, the lamp board 23, and the polarization adjustment member 22 can be passed through the corresponding assembly holes in sequence and fixed together with nuts to ensure the structural stability of the lamp assembly 2.
