Embodiment 1

[0025] see Figure 1 to Figure 4 As shown, the present embodiment discloses a lamp 1000, and the lamp 1000 is described as a light bulb in this embodiment, but the present invention is not limited thereto. Wherein, the lamp 1000 includes a combined lens 100 , a light emitting unit 200 corresponding to the position of the combined lens 100 , and a bearing seat 300 for mounting the combined lens 100 and the light emitting unit 200 . Furthermore, the combined lens 100 used in the lamp 1000 of this embodiment is preferably suitable for the lighting field, so it is different from lenses in other fields (such as: imaging field).

[0026] It should be noted that the above combined lens 100 and light emitting unit 200 can also be named as a light emitting module in this embodiment. In this embodiment, the combined lens 100 is matched with the light emitting unit 200 and the bearing seat 300; in other words, the light emitting module is matched with the bearing seat 300, but the prese...

Embodiment 2

[0046] see Figure 5 As shown, it is Embodiment 2 of the present invention. This embodiment is similar to the above-mentioned Embodiment 1, so the similarities between the two embodiments will not be repeated, and the difference between this embodiment and the above-mentioned Embodiment 1 is mainly In: the combined lens 100 .

[0047] In this embodiment, the combined lens 100 further includes a light-transmitting adhesive layer 4 filled between the light-diffusing surface 23 and the exit surface 15 (that is, the gas-phase medium layer 3 is transparent to the light as described above). glue layer 4 ), and a plurality of light-diffusing microstructures 231 are embedded in the light-transmitting glue layer 4 .

[0048] Wherein, the outgoing surface 15 and the light diffusing surface 23 are completely covered and bonded by the light-transmitting adhesive layer 4 in this embodiment, so the relative position between the first lens part 1 and the second lens part 2 It may be fixed ...

Embodiment 3

[0050] see Figure 6 As shown, it is the third embodiment of the present invention. This embodiment is similar to the above-mentioned embodiment one, so the similarities between the two embodiments will not be repeated, and the difference between this embodiment and the above-mentioned embodiment one is mainly In: the light emitting module.

[0051] In this embodiment, the surface of the first lens part 1 only includes a ring side surface 11, an incident surface 12 located inside the above-mentioned ring side surface 11, and an incident surface 12 located on the opposite side of the incident surface 12 and connected to the ring side surface 11. An outgoing surface 15 (that is, the first lens portion 1 does not form the above-mentioned side incident surface 13 and reflective surface 14). Wherein, the incident surface 12 also surrounds and forms a groove-shaped space 123 , the light-emitting unit 200 falls on the central axis C, and at least part of the light-emitting unit 200 ...

Abstract

The invention discloses a lamp, a light-emitting module and a combined lens of the light-emitting module. The combined lens comprises a first lens part and a second lens part which are kept fixed in relative positions. The first lens part comprises a ring side surface which can be used for reflecting light rays, an incident surface located on the inner side of the ring side surface and an emergentsurface located on the opposite side of the incident surface. The second lens part comprises a light diffusing surface and a light-emitting surface which are located on opposite sides, and the lightdiffusing surface and the light-emitting surface are arranged opposite to each other and spaced apart from each other. A plurality of light diffusing microstructures are formed on the light diffusingsurface, and the light diffusing microstructures are right projected on the projection area of the light diffusing surface at the emergent surface. The incident surface is used for allowing light raysto pass through to enter the combined lens, so that the light rays in the combined lens can pass through the emergent surface and the light diffusing microstructures and are emitted from the combinedlens through the light-emitting surface. Accordingly, by forming the light diffusing microstructures on the inner side of the combined lens, the influence of external factors is effectively avoided.

Description

technical field [0001] The invention relates to a lens, in particular to a lamp, a light emitting module and a combined lens thereof. Background technique [0002] In order to make the light emitted by the existing lens uniform, light diffusion treatment is usually carried out on the outside of the lens (such as: the light-emitting surface). However, the light diffusion part formed by the existing lens is easily affected by external factors, which weakens its uniform effect. Contents of the invention [0003] Embodiments of the present invention provide a lamp, a light emitting module and a combined lens thereof, which can effectively improve possible defects of existing lenses. [0004] The embodiment of the present invention discloses a lamp, comprising: a combined lens, including: a first lens part, including a ring side surface capable of reflecting light, an incident surface located inside the ring side surface, and a An exit surface on the opposite side of the inci...
