Abstract
The utility model discloses a wedge-shaped clapboard for light conducting and lighting equipments employing the clapboard, which can increase the light range and efficiency, and only a LED light source is used by the lighting equipments, thereby completing the need for lighting and increasing the light range and efficiency, wherein a micro convex lens is mounted on the novel clapboard for light conducting, whose number, size and location could be determined by the actual need. The utility model is applicable to the face plate of portable illuminating facility, consisting of a LED light source for providing light source, a wedge-shaped clapboard for light conducting which is used to conduct the light source to the location needed, and a micro convex lens is mounted on the novel clapboard for light conducting, whose number, size and location could be determined by the actual need. Additionally, this novel lighting equipment comprises a reflector cover arranged around the LED light source and reflecting papers positioned on the lower or lateral side of the wedge-shaped clapboard for light transmitting.
Description
Technical field
The utility model relates to a kind of wedge shape light guide plate, also relates to a kind of light fixture in addition.
Background technology
Existing handheld device, such as mobile phone, personal digital equipment such as PDA, their outward appearance fashion is beautiful, the element of enhancing visual impacts such as utilization color, light is introduced in the appearance design more and more, and different designing requirements has various color light as requested to outward appearance.Traditional implementation method is the LED lamp direct illumination that increases monochrome or polychrome at the position of needs, and illuminating if any a plurality of local requirements then increases a plurality of LED lamps, but has following problem:
1. the position uneven illumination that is illuminated is even, and the position that LED directly shines is bright excessively, and illumination range is little, and efficient is low.This mainly is because the light guide effect of light guide plate is bad, causes that light attenuation and loss are too fast to be caused.
2. because of adopting a plurality of LED, the electronic circuit complicacy increases, and power consumption also increases, and this is disadvantageous to handheld device.
The utility model content
Technical problem to be solved in the utility model provides a kind of wedge shape light guide plate, and it can provide the secondary luminous point, and then has improved illumination range and efficient.
In order to solve above technical matters, the utility model provides a kind of wedge shape light guide plate, and described wedge shape light guide plate is provided with miniature convex lens, and the quantity of miniature convex lens, size and position can be set according to actual needs.
In addition, another problem of technology to be solved in the utility model provides a kind of light fixture, and it can only need a led light source, can finish the illumination needs, and improve illumination range and efficient.
In order to solve above technical matters, the utility model provide a kind of it be applied to illuminate the panel of handheld device, it comprises: a led light source provides light source; A wedge shape light guide plate is used for described led light source is directed to the place of needs, and described wedge shape light guide plate is provided with miniature convex lens, and the quantity of miniature convex lens, size and position can be set according to actual needs.
It also comprises a reflection shield, is used for light concentrated projecting light guide plate, be arranged on led light source around.
It comprises also and being arranged on below the wedge shape light guide plate or/and the reflective sheeting of side that the quantity and the position of reflective sheeting are set according to actual needs.
Because light guide plate of the present utility model is combined with miniature convex lens, in the conductive process of light, miniature convex lens can form the secondary luminous point so, and then have improved illumination range and efficient.In addition, light fixture of the present utility model has adopted above-mentioned light guide plate, so just can reach the effect that light any luminous many places, not only can finish the illumination needs, and improve illumination range and efficient.Reflection shield that is provided and reflective sheeting have further improved illumination range and efficient.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
Fig. 1 is a wedge shape light conducting plate structure synoptic diagram of the present invention;
Fig. 2 is a light fixture structural representation of the present invention;
Fig. 3 is a light fixture structural upright synoptic diagram of the present invention.
Embodiment
As shown in Figure 1, it is an invention wedge shape light conducting plate structure synoptic diagram.Wedge shape light guide plate 1 is made up of body 3 and the miniature convex lens 2 that are embedded on the body 3, and its upper surface is that reflecting surface 4 is milled sand surface, is cammed surface 5 below, and its angle of inclination a sets as required, generally between the 0.5-1 degree.Wedge shape light guide plate 1 is made by PMMA (polymethylmethacrylate is called organic glass usually) usually, and the refractive index of its D light is 1.482, can adopt mold injects to be shaped.
So-called milled sand surface is meant that the upper surface of wedge shape light guide plate 1 is distributed with a large amount of sags and crests, and this is for scattering creates conditions, and makes the light of outgoing reach irreflexive fruit, and printing opacity is even.
Miniature convex lens 2 generally are located on the cammed surface 5, it and wedge shape light guide plate 1 one volume imagings, it is mainly used in reflection from led light source or the light injected through other direction, and with light be transmitted to the outside, become miniature one by one luminous point, also can be according to the requirement of appearance design, with miniature convex lens enlarged diameter to about the 2-2.5mm, form some bigger secondary luminous points, reach the fruit that light any luminous many places.What of its quantity are also set as required.
Shown in Fig. 2,3, they are respectively light fixture structural representation of the present invention and schematic perspective view.It is made up of wedge shape light guide plate 1, led light source 6 at least.
Be provided with reflection shield 7 in addition around led light source 6, the major function of reflection shield 7 mainly is the light of led light source 6 to be concentrated be projeced in the light guide plate.
In addition, also around wedge shape light guide plate 1, be added with reflective sheeting 8 as required, some sticks to wedge shape light guide plate 1 below reflective sheeting 8, its function is to be projected to above light on it reflexes to, also need to stick on reflecting paper 8 at the sideway stance that does not need printing opacity, it can make light return light guide plate again, to improve the utilization factor of light.Reflecting paper 8 can be to make separately, also can add plating one deck reflectance coating and make on wedge shape light guide plate 1 surface.
