Abstract
The invention relates to an optical module. The optical module comprises an LED (light-emitting diode) light source and a housing, wherein an optical cavity is formed in the housing, the optical cavity is provided with a light inlet and a light outlet, and light of the LED light source enters the optical cavity from the light inlet, is reflected by the inner surface of the housing and then emerges from the light outlet. The optical module provided by the invention can not only realize light extraction from multiple surfaces, but also realize simple structure. The invention further relates to a lamp, and the lamp comprises the optical module.
Description
Technical field
The present invention relates to lighting field, particularly relate 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, reading or be engaged in other work with person easy to use.Because the light of this desk lamp penetrates, although the brightness of regional area can be improved, good decoration function can not be played downwards.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of optics module.
In order to solve above technical problem, optics module of the present invention 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, and the light of described LED light source enters described optics cavity and from described light-emitting window outgoing after the internal surface reflection of described housing from described light inlet.
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 with the mode of described housing by clamping; 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, thus forms special illumination and decorative effect, and structure is relatively simple.
The present invention 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 sectional view of a kind of embodiment of optics module of the present invention.
Detailed description of the invention
Below in conjunction with Fig. 2, a kind of embodiment of the present invention is described in detail.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 enters described optics cavity 21 and from the outgoing of described light-emitting window 23 after the inner surface 25 of described housing 2 reflects from described light inlet 22.Like this, through the effect of described housing 2, the light of LED light source 1, from the outgoing of each light-emitting window 23, is irradiated to all directions around described optical axis, thus forms special illumination and decorative effect, and structure is relatively simple.Described light-emitting window 23 is provided with diffusion shell 9, by arranging diffusion shell 9, light can be made more even, soft.Described diffusion shell 9, in spherical, by diffusion shell 9 is arranged to spherical crown shape, is compared with flat diffusion shell, and lighting area is larger, thus 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 invention not only can realize multiaspect bright dipping, and structure is simple.
As the simple deformation of the present embodiment, described diffusion shell is connected with the mode of described housing by clamping; Or described diffusion shell and described housing are threaded connection.
The present invention also provides a kind of light fixture, and this light fixture comprises aforesaid optics module.
