[0025] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] In the description of the present invention, it should be understood that if terms such as "center", "middle part", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc. are used to indicate the orientation or positional relationship, it is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0027] As shown in Figure 1 to Figure 4 the drawings, the present invention provides a lamp with large-angle light output, including a lamp body 1 having an accommodation cavity 10. The accommodation cavity 10 is provided with a light outlet 11. The lamp body 1 is fixedly provided with a first light-transmitting member 2 for closing the light outlet 11. Specifically, the first light-transmitting member 2 is a circular lens, and the light incident surface of the lens is an array of compound eyes lenses, and its main function is to obtain high light energy utilization rate and large-area uniform illumination.

[0028] A first light-emitting element 3 is fixedly arranged below the first light-transmitting member 2 and within the accommodation cavity 10. The first light-emitting element 3 is disposed adjacent to the inner edge of the light-emitting opening 11 and is arranged in a surrounding manner. Specifically, the first light-emitting element 3 includes an annular lamp board and a plurality of LED lamp beads fixedly arranged on the annular lamp board. A second light-transmitting member 4, which is annular in shape and is directly opposite to the position of the first light-emitting element 3, is fixedly arranged above the first light-transmitting member 2 and outside the accommodation cavity 10. The second light-transmitting member 4 has a light-emitting surface for diffusing light. The light of the first light-emitting element 3 is emitted successively through the first light-transmitting member 2 and the second light-transmitting member 4. The second light-transmitting member 4 is an annular lens, and its upper surface is the light-emitting surface for diffusing light, which can change the light path while allowing light to pass through, so as to achieve a large-angle light-emitting effect.

[0029] As shown in the Figure 3 and Figure 4 accompanying drawings, the second light-transmitting member 4 is provided with a first annular protrusion 41 protruding upward, so that its upper surface has a light-emitting surface for diffusing light in an arc shape. The bottom surface of the second light-transmitting member 4 is a plane, and this plane is in fitting connection with the upper end surface of the first light-transmitting member 2. Preferably, the light-emitting surface is in an arc shape, which can achieve a better light-diffusing effect, thereby realizing the large-angle light emission of the lamp.

[0030] As shown in the Figure 3 and Figure 4 accompanying drawings, the topmost height of the first annular protrusion 41 is greater than the topmost height of the light-emitting opening 11, preferably 1 to 2 mm higher, effectively increasing the illumination range of the light-emitting opening and preventing the light emitted from the first light-transmitting member 2 from being blocked by the edge of the light-emitting opening 11, so that a better light and shadow effect can also be experienced from the side of the lamp.

[0031] As shown in the Figure 3 and Figure 4 accompanying drawings, the lower end surface of the first light-transmitting member 2 is provided with a second annular protrusion 21 protruding downward, so that the lower surface of the first light-transmitting member 2 has a light-incident surface in an arc shape. The light-incident surface of the second annular protrusion 21 is directly opposite to the first light-emitting element 3, and this light-incident surface can effectively increase the incident range of the incident light, that is, collect more incident light and reduce the loss of incident light.

[0032] As shown in the Figure 2 to Figure 4 accompanying drawings, an annular fixing member 5 is fixedly arranged within the accommodation cavity 10 of the lamp body 1. The annular fixing member 5 includes an annular base 51, an inner annular portion 52 arranged on the inner ring side of the annular base 51, and an outer annular portion 53 arranged on the outer ring side of the annular base 51. An annular groove 50 with an upward notch and for accommodating the first light-emitting element 3 is formed between the inner annular portion 52 and the outer annular portion 53, which is beneficial to the installation of the lamp board of the first light-emitting element 3.

[0033] As shown in theFigure 4 As shown, the second annular protrusion 21 extends into the annular groove 50 through the notch. In addition to providing a mounting location for the lamp board, the annular groove 50 can also block light, allowing the light from the first light-emitting component 3 to only enter the light-incident surface of the second annular protrusion 21 after passing through the notch of the annular groove 50, further reducing light loss.

[0034] As shown in the attached Figure 6 As shown, a number of ribs 54 are distributed around the bottommost end of the annular base 51. These ribs 54 can not only strengthen the strength of the annular base but also act as a heat sink for the first light-emitting component 3.

[0035] As shown in the attached Figure 4 and the attached Figure 5 As shown, an inwardly protruding annular flange 12 is provided at the light-emitting opening 11 such that the annular flange 12 and the side wall of the light-emitting opening 11 form an annular step 13. The second light-transmitting member 4 is provided with an annular collar 42 integrally formed with the first annular protrusion 41. The annular collar 42 is fitted and disposed on the annular step 13 while sleeving the outer peripheral surface of the first light-transmitting member 2. The upper and lower ends of the annular collar 42 are respectively and hermetically connected to the annular flange 12 and the outer annular portion 53. Specifically, the first annular protrusion 41 and the annular collar 42 are made as a single unit, enabling the second light-transmitting member 4 to not only diffuse light but also provide a waterproof function, mainly preventing water from entering the light-emitting opening and enhancing the sealing performance of the accommodation cavity.

[0036] As shown in the attached Figure 3 As shown, a second light-emitting component 6 and a reflector cup 7 covering the second light-emitting component 6 are fixedly provided in the accommodation cavity 10. The light from the second light-emitting component 6 is emitted through the reflector cup 7 and the first light-transmitting member 2. Similarly, the second light-emitting component 6 includes a lamp board and LED lamp beads fixed on the lamp board, further enriching the light and shadow effects and functions of the lamp.

[0037] As shown in the attached Figure 3 As shown, the light-emitting port of the reflector cup 7 is turned outward to form an annular flange 71. A number of the ribs 54 enclose an annular opening 540. The reflector cup 7 is adapted to the annular opening 540 through the annular flange 71, making the internal structure of the lamp more compact, stable, and convenient for assembly.

[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various equivalent changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalent scope.
