Abstract
The utility model relates to an optics module which comprises an LED light source and a shell body. The shell body is provided with an optics cavity which is provided with a light-in opening and a plurality of light-out openings. At least part of the light-out openings surround the optical axis of the LED light source. Light of the LED light source enters the optics cavity from the light-in opening, is reflected by the inner surface of the shell body and then is emitted out from the light-out openings. The optics module can achieve multi-face light emitting out, and the structure is simple. The utility module further provides a lamp which comprises the optics module.
Description
Technical field
The utility model relates to lighting field, relates in particular to a kind of light fixture and optics module thereof.
Background technology
Fig. 1 is the schematic diagram of a kind of desk lamp of the prior art.This desk lamp comprises LED light source 100, lampshade 200, vertical rod 300 and base 500.LED light source 100 is arranged in lampshade 200, and the light of LED light source 100 penetrates downwards, for improving the brightness of regional area, reads or be engaged in other work with person easy to use.Because the light of this desk lamp penetrates, although can improve the brightness of regional area, can not play good decoration function downwards.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of optics module.
In order to solve above technical problem, optics module of the present utility model comprises LED light source and housing, described housing is provided with optics cavity, described optics cavity is provided with light inlet and light-emitting window, the quantity of described light-emitting window is multiple, at least part of described light-emitting window is around the optical axis of described LED light source, the light of described LED light source from described light inlet enter described optics cavity and after the internal surface reflection of described housing from described light-emitting window outgoing.
Preferably, described light-emitting window is provided with diffusion shell.
Preferably, described diffusion shell is spherical.
Preferably, described diffusion shell is connected by bonding mode with described housing; Or described diffusion shell is connected by the mode of clamping with described housing; Or described diffusion shell and described housing are threaded connection.
Preferably, the inner surface of described housing is fully reflecting surface.
Preferably, the quantity of described light-emitting window is more than 2.
Preferably, described housing is rotary structure, and described light-emitting window is evenly distributed on described housing.
Through the effect of described housing, the light of LED light source, from each light-emitting window outgoing, is irradiated to all directions around described optical axis, thereby forms special illumination and decorative effect, and structure is relatively simple.
The utility model also provides a kind of light fixture, comprises the optics module described in aforementioned any one.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of light fixture of the prior art;
Fig. 2 is the cutaway view of a kind of embodiment of optics module of the present utility model.
The specific embodiment
Below in conjunction with Fig. 2, a kind of embodiment of the present utility model is elaborated.The optics module of the present embodiment comprises LED light source 1 and housing 2, and described housing 2 can be made up of plastics or other materials.Described housing 2 is provided with optics cavity 21, and described optics cavity 21 is provided with light inlet 22 and light-emitting window 23, and the quantity of described light-emitting window 23 is multiple, and at least part of described light-emitting window 23 is around the optical axis of described LED light source 1.As shown in Figure 2, down, the longitudinal centre line of described housing 2 is the optical axis of LED light source 1 to the light-emitting area of described LED light source 1.In the present embodiment, all light-emitting windows 23 are all around described optical axis.The light of described LED light source 1 from described light inlet 22 enter described optics cavity 21 and after inner surface 25 reflection of described housing 2 from described light-emitting window 23 outgoing.Like this, through the effect of described housing 2, the light of LED light source 1, from each light-emitting window 23 outgoing, is irradiated to all directions around described optical axis, thereby forms special illumination and decorative effect, and structure is relatively simple.Described light-emitting window 23 is provided with diffusion shell 9, by diffusion shell 9 is set, can make light more even, soft.Described diffusion shell 9 is spherical, by diffusion shell 9 is arranged to spherical crown shape, compares with flat diffusion shell, and lighting area is larger, thereby makes light softer, and has third dimension.Described diffusion shell 9 is connected by bonding mode with described housing 2.The inner surface 25 of described housing 2 is fully reflecting surface, by inner surface 25 is arranged to fully reflecting surface, can reduce the loss of the light of LED light source, improves light extraction efficiency.Described housing 2 is rotary structure, and described light-emitting window 23 is evenly distributed on described housing 2.Optics module of the present utility model not only can be realized multiaspect bright dipping, and simple in structure.
As the simple deformation of the present embodiment, described diffusion shell is connected by the mode of clamping with described housing; Or described diffusion shell and described housing are threaded connection.
The utility model also provides a kind of light fixture, and this light fixture comprises aforesaid optics module.
