Specific embodiment
To keep the technical problems solved, the adopted technical scheme and the technical effect achieved by the invention clearer, below
It will the technical scheme of the embodiment of the invention will be described in further detail in conjunction with attached drawing, it is clear that described embodiment is only
It is a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those skilled in the art exist
Every other embodiment obtained under the premise of creative work is not made, shall fall within the protection scope of the present invention.
As shown in Figure 1, the device includes reflecting plate 1, light-guide device 2 and shines the present embodiment provides a kind of optics module
Unit, 1 side of reflecting plate are reflective surface, and the other side is shady face, and at least partly light-guide device 2 is located at reflective surface edge.It shines
Unit is located at outside light-emitting surface, there is no need to the aperture on reflecting plate 1, solves the whole light that reflecting plate 1 is destroyed because of aperture
Uniformity and there are problems that dark space in tapping.And the light emission that luminescence unit issues enters light-guide device 2 and by positioned at reflective
The part light-guide device 2 at face edge is radiated to reflective surface, and therefore, the light-guide device added will not form new dark in reflective surface
Area, and the uniformity for being radiated to the light of the surface of emission is improved by light-guide device.
Light-guide device 2 includes sequentially connected first light-guide device 21 and the second light-guide device 22, the first light-guide device 21
Except 1 overlay area of reflecting plate, i.e., the first light-guide device 21 is located at outside visible area, first light-guide device of the present embodiment
21 and second light-guide device 22 be integrally formed setting.One end of second light-guide device 22 is located at the shady face of reflecting plate 1, the other end
Be connected to the first light-guide device 21, the light emission that luminescence unit issues enters the second light-guide device 22, and by the second light-guide device 22 into
Enter the first light-guide device 21, then is radiated on the reflective surface of reflecting plate 1 by the first light-guide device 21.
Define 21 head and the tail both ends line of the first light-guide device extending direction be direction initialization, in order to increase light emitting region and
Improve luminous uniformity, it is desirable that projected length of first light-guide device 21 on direction initialization is more than or equal to reflecting plate 1
Projected length on direction initialization.The shape of first light-guide device 21 and reflecting plate with 21 corresponding part of the first light-guide device
1 edge shape is identical, and the light for reflecting reflecting plate 1 is more uniform.Preferably, the first light-guide device 21 and reflecting plate 1 away from
From in safety clearance, which is 0.5mm-3mm.
Said reflection plate 1 is sequentially smoothly connected by multiple planes and/or curved surface, as shown in Figures 2 and 3, this implementation
The reflecting plate 1 of example is triangle reflecting plate, which is free form surface made of smoothly being connected as multiple curved surfaces, the reflecting plate
1 is defined as the longest edge of reflecting plate 1 along the maximum length of the length direction for the part light-guide device 2 for being located at reflective surface edge, the
The length of one light-guide device 21 is more than or equal to the length of longest edge, and the shape of the shape of the first light-guide device 21 and the longest edge
It is identical.Certainly reflecting plate 1 of the invention is not limited to the triangle reflecting plate of the present embodiment, can also be that half paraboloid reflects
Plate, rectangle reflecting plate or circular reflector etc. are made with specific reference to the shapes and sizes of actual needs self-defining reflecting plate 1
Type is freer.
In order to which the light emission for issuing luminescence unit enters light-guide device 2, luminescence unit is at a distance from light-guide device 2
0.15mm-1mm, it is preferable that luminescence unit is 0.5mm at a distance from light-guide device 2.The luminescence unit of the present embodiment is LED hair
Light unit 3, specially LED point light source or LED bulb are arranged with specific reference to actual needs.The present embodiment uses LED luminescence unit
3, it is because it has the characteristics that energy is concentrated and directive property is strong, i.e. LED luminescence unit 3 is compared with Conventional luminescent unit, hair
Light out is orientation, and the most of light issued from LED luminescence unit 3 can be emitted directly toward light-guide device 2, and utilization rate is far high
In Conventional luminescent unit.Conventional luminescent unit is analogous to the luminescence unit of light bulb, and its light is more dispersed, generally not as
Luminescence unit.And light-guide device 2 is used as line luminescence unit, length can be set according to actual needs, and guarantee light-guide device 2
Under the premise of shining uniformly, the length maximum of light-guide device 2 can accomplish 350mm-500mm, and light-guide device 2 is longer, export
Light after triangle reflecting plate 1 is reflected, range of exposures is bigger, due to light-guide device 2 shine it is relatively uniform, derived from
Light is also relatively uniform after triangle reflecting plate 1 is reflected.
The present embodiment compared with prior art, is not necessarily to remain the integrality of reflecting plate 1 in 1 borehole of reflecting plate, pass through
The concept of " point-line-face " will be located at original luminescence unit of the LED luminescence unit 3 outside reflective surface as the optics module,
And line luminescence unit, and then original luminescence unit of the light-guide device 2 as reflecting plate 1 are converted thereof by light-guide device 2, it protects
The luminous uniform of entire reflecting plate 1 is demonstrate,proved, since the light of line luminescence unit can be irradiated to large area, to make the present embodiment institute
The irradiation area of the optics module of offer is bigger.
The present embodiment additionally provides a kind of lamps and lanterns, including optics module described in any of the above-described scheme.It further include barn door,
Barn door is located at 2 front of light-guide device, and some light that barn door can stop light-guide device 2 to issue issues light-guide device 2
Light reflected from reflective surface, cannot directly can't see light-guide device 2 in visible area, the light that LED luminescence unit 3 issues is not straight
Visible area was connected to emit, and the light for issuing lamps and lanterns is more uniform.
Note that the above is only a better embodiment of the present invention and the applied technical principle.It will be appreciated by those skilled in the art that
The invention is not limited to the specific embodiments described herein, be able to carry out for a person skilled in the art it is various it is apparent variation,
It readjusts and substitutes without departing from protection scope of the present invention.Therefore, although being carried out by above embodiments to the present invention
It is described in further detail, but the present invention is not limited to the above embodiments only, without departing from the inventive concept, also
It may include more other equivalent embodiments, and the scope of the invention is determined by the scope of the appended claims.
