Abstract
Description
Technical Field
[0001] This utility model relates to the field of lighting technology, and in particular to a 180-degree upward-emitting light source for lighting fixtures. Background Technology
[0002] Currently, with the development of indoor decorative lighting and ambient lighting, users have placed higher demands on the lighting effects of lamps. Traditional ceiling lights, chandeliers, or wall lights mostly emit light downwards or through secondary light distribution via reflectors. However, in many scenarios where the ceiling needs to be illuminated, the light source needs to have upward-emitting characteristics, i.e., an "upward-emitting" light source.
[0003] In existing technologies, LED beads are soldered onto an aluminum substrate or FR-4 fiberglass board, and upward illumination is achieved by mounting the entire light source module facing the ceiling. However, due to the limitations of the planar substrate structure, the beam angle of a single LED bead is typically only around 120°. Even with arrangement and combination, the overall effective illumination angle of this type of light source is difficult to exceed 120°-140°, easily producing noticeable dark areas or uneven light spots near the ceiling, making it impossible to achieve near 180° uniform illumination in a semi-space. Summary of the Invention
[0004] The purpose of this invention is to provide a 180-degree upward-emitting light source for lighting fixtures, which can solve at least one of the above-mentioned technical problems. The technical solution of this invention is as follows:
[0005] A 180-degree upward-emitting light source for a lamp fixture includes: an upper lamp plate, and a plurality of upper light-emitting groups are installed above the upper lamp plate;
[0006] The upper light-emitting group includes a first mounting profile fixed above the upper light panel, a plurality of first LED light sources are mounted on the first mounting profile, a plurality of 180-degree scattering lenses are spaced apart above the first mounting profile, and a fixing mechanism is provided on the first mounting profile to fix the 180-degree scattering lenses to the upper light panel.
[0007] Furthermore, the 180-degree scattering lens includes multiple arc-shaped light-transmitting mirrors spaced apart above the upper light panel. A light source channel is provided in the middle of the lower part of each arc-shaped light-transmitting mirror. The light source channel gradually narrows from bottom to top, and wavy patterns are provided on the left and right sides of the light source channel and below the arc-shaped light-transmitting mirrors.
[0008] Furthermore, the fixing mechanism includes multiple first buckles on the left and right sides of the curved light-transmitting mirror, hooks fixedly provided on the left and right sides of the first mounting profile, fixing covers provided on the ends of the curved light-transmitting mirror located at the rearmost side and the curved light-transmitting mirror located at the frontmost side, and second buckles symmetrically fixed below each fixing cover.
[0009] Furthermore, the arc of the curved light-transmitting mirror is 0.5 radians, and the included angle of the light source channel is 16 degrees.
[0010] A 180-degree upward-illuminating light source for a lamp fixture has a second mounting profile symmetrically fixed on an upper lamp plate. Each of the second mounting profiles has an oblique mounting groove that can be obliquely angled to the left and right sides. A second LED light source is fixed in each of the oblique mounting grooves, and a 90-degree emitting lens is inserted into each of the oblique mounting grooves.
[0011] Furthermore, the 90-degree scattering lens includes a semi-circular lens that is movably inserted into an oblique mounting slot, and a light-transmitting channel with an included angle of 85 degrees is provided in the lower center of the semi-circular lens.
[0012] Furthermore, the semi-circular lens has an arc of 1.8 radians, and the inclined angle of the oblique mounting groove is 15 degrees.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0024] like Figures 1 to 3 The above-displayed 180-degree upward-emitting light source for a lamp is characterized by comprising: an upper lamp plate 1, and a plurality of upper light-emitting groups 2 installed above the upper lamp plate 1;
[0025] The upper light-emitting group 2 includes a first mounting profile 3 fixed above the upper light plate 1, a plurality of first LED light sources 4 are mounted on the first mounting profile 3, a plurality of 180-degree scattering lenses 5 are spaced apart above the first mounting profile 3, and a fixing mechanism 6 is provided on the first mounting profile 3 to fix the 180-degree scattering lenses 5 on the upper light plate 1.
[0026] The fixing mechanism 6 includes multiple first buckles 61 on the left and right sides of the curved light-transmitting mirror 51, hooks 62 fixedly provided on the left and right sides of the first mounting profile 3, and fixing covers 63 provided on the ends of the curved light-transmitting mirror 51 located at the rearmost side and the curved light-transmitting mirror 51 located at the frontmost side. Second buckles 64 are symmetrically fixed below each fixing cover 63.
[0027] The above structure is used for a 180-degree upward-emitting light source for a lamp. In use, the user installs the required number of upper light-emitting groups 2 according to the length of the upper lamp plate 1. During installation, the user can fix the 180-degree emitting lens 5 on the first mounting profile 3 through the fixing mechanism 6. During installation, the user first inserts the fixing cover 63 into the ends of the curved light-transmitting mirror 51 on the last and first sides. Then, the fixing cover 63 and the curved light-transmitting mirror 51 are fastened and fixed to the hook 62 by the first buckle 61 and the second buckle 64, respectively. In daily lighting use, the 180-degree emitting lens 5 is illuminated by the first LED light source 4, so that the 180-degree emitting lens 5 emits a 180-degree illumination light source to the environment. Compared with the prior art, it can form a 180-degree range of upward illumination angle for the lamp.
[0028] like Figure 3 As shown, in some embodiments of this utility model, the 180-degree scattering lens 5 includes a plurality of arc-shaped light-transmitting mirrors 51 spaced apart above the upper lamp plate 1. A light source channel 52 is provided in the middle of the lower part of each arc-shaped light-transmitting mirror 51. The light source channel 52 gradually narrows from bottom to top. Wavy patterns 53 are provided on the left and right sides of the light source channel 52 and below the arc-shaped light-transmitting mirror 51.
[0029] The arc-shaped light-transmitting mirror 51 has an arc of 0.5 radians, and the included angle of the light source channel 52 is 16 degrees.
[0030] The above structure is used for a 180-degree illumination light source in a lamp. The light source is illuminated in the light source channel 52 by the first LED light source 4. Since the included angle of the light source channel 52 is 16 degrees, the light source is refracted for the first time in the curved light-transmitting mirror 51 through its angle. The light source is finally refracted and emitted by the curved surface of the curved light-transmitting mirror 51. The curved surface of the curved light-transmitting mirror 51 with an arc of 0.5 radians folds the light source again and emits it. After two refractions, the light source forms a 180-degree illumination range.
[0031] like Figures 4 to 6 As shown, in some embodiments of this utility model, a 180-degree upward-emitting light source for a lamp is characterized by second mounting profiles 7 symmetrically fixed on an upper lamp plate 1, each of the second mounting profiles 7 having oblique mounting grooves 8 that can be obliquely directed to the left and right sides, a second LED light source 9 fixed on each of the oblique mounting grooves 8, and a 90-degree emitting lens 10 inserted into each of the oblique mounting grooves 8.
[0032] The 90-degree scattering lens 10 includes a semi-circular lens 101 that is movably inserted into the oblique mounting slot 8, and a light-transmitting channel 102 with an included angle of 85 degrees is provided in the lower center of the semi-circular lens 101.
[0033] The semicircular lens 101 has an arc of 1.8 radians, and the inclined mounting groove 8 has an angle of 15 degrees.
[0034] Cover plates 71 are provided on the front and rear sides of each of the second mounting profiles 7.
[0035] The above structure is used for a 180-degree illumination light source in a lamp. In use, the light source 9 is irradiated through a second LED light source 9 and a 90-degree radiating lens 10. The second LED light source 9 undergoes a first refraction through a light transmission channel 102 with an 85-degree angle within the 90-degree radiating lens 10. Then, the light source undergoes a second refraction through a semi-circular lens 101 with an arc of 1.8 arcs, so that the light source refracts to create a 90-degree illumination range. Since each of the second mounting profiles 7 is symmetrically arranged on the upper lamp plate 1, and the angle of the oblique mounting grooves 8 on the second mounting profiles 7 is 15 degrees, the light sources that are symmetrically arranged to emit a 90-degree illumination range are combined and used to achieve a 180-degree illumination range.
[0036] The foregoing has shown and described the basic principles and main features of this utility model, as well as its advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are only illustrative of the principles of this utility model. Various changes and modifications may be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of this utility model as claimed.
