Specific embodiment
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
As shown in Figure 1 to Figure 3, the utility model provides a kind of light guide module, which includes light guide 1 and red
Infrared receiving device 2, in which:
Light guide 1 includes that the incidence surface 11, reflecting surface 12 and the light-emitting surface 13 that set gradually are moved towards along optical path, reflecting surface 12 with
Light-emitting surface 13 is opposite and is arranged in parallel, and incidence surface 11 and reflecting surface 12 are obliquely installed, and the relative position of the two forms half arc
Shape.The light guide 1 of the utility model using its incidence surface 11 and reflecting surface 12 and the two that are obliquely installed relative position shape
At half arc, so that increasing from the light that incidence surface 11 enters reflecting surface 12, and reflecting surface 12 and light-emitting surface 13 are located at same water
Flat height, so that light is more uniformly projected from light-emitting surface 13.It is understood that when only existing an inclined incidence surface 11
When light-emitting surface 13 corresponding thereto, reflected after light enters incidence surface 11, having some light can be from incidence surface 11
Bottom project and be wasted, do not guarantee that this some light is not wasted, be incidence surface 11 it is opposite bottom setting inclination
The reflecting surface 12 of setting, in this way, from the light that 11 bottom of incidence surface is projected light-emitting surface 13, Jin Erbao can be reflected by reflecting surface 12
Most light that card enters incidence surface 11 are projected by light-emitting surface 13, and can more uniformly be projected from light-emitting surface 13.
Specifically, light guide 1 further include scattering surface in addition to incidence surface 11, reflecting surface 12 and light-emitting surface 13 (in figure not
Indicate), scattering surface is handled using frosted.So set, the light into incidence surface 11 can be made when reaching scattering surface,
It can be scattered out, after n times scatter, can reflected through reflecting surface 12 and emitted face by the scattering surface handled through frosted
Scattering area scattering between 12 and light-emitting surface 13, so that the light that light-emitting surface 13 projects is more uniform, (optical path trend please join
It reads dotted line in Fig. 3 to indicate, wherein not indicating the light trend scattered in light guide 1).
Specifically, infrared receiving device 2 is equipped with light source 21, and light source 21 is preferably LED light, and light source 21 and incidence surface 11 hang down
Straight setting, incidence surface 11 and reflecting surface 12 are using polishing or electroplating processes.Incidence surface 11 uses polishing or electroplating processes, and light source
21 are vertically arranged with incidence surface 11, and may make incidence surface 11 enters the more (light reflected away by incidence surface 11 of light
Less)；And reflecting surface 12 can then be made to enter the light inside light guide 1 and be reached reflecting surface 12 using polishing or electroplating processes
It when place, can be reflected by reflecting surface 12, (theoretically exist only in light to hang down so that the light projected through reflecting surface 12 greatly reduces
Situation until reaching reflecting surface 12, it may occur that light transmits reflecting surface 12).Preferably, distance of the light source 21 away from incidence surface 11
For 5mm~10mm, can make incidence surface 11 at this time enters that light effect is more excellent, i.e., incident ray is more.
Specifically, Fig. 1 and Fig. 2 are please referred to, light guide 1 further includes buckle 14, and infrared receiving device 2 further includes card slot 22,
Buckle 14 and card slot 22 are clamped, so as to facilitate the disassembly of light guide 1 and infrared receiving device 2.It is understood that the two
It can also be connected by other connection types, such as be threadedly coupled and connected with gluing.Specifically, light guide 1 further includes installation position 15,
Light guide 1 can be mounted on to the suitable position of inside television by installation position 15.
Specifically, infrared receiving device 2 further includes infrared receiving terminal 23, and infrared receiving terminal 23 is opposite and flat with reflecting surface 12
Row setting, infrared receiving terminal 23 and light-emitting surface 13 are divided into the two sides of reflecting surface 12.When personnel utilize infrared signal by remote control
When being transferred to infrared receiving terminal 23, since infrared receiving terminal 23 and light-emitting surface 13 are divided into the two sides of reflecting surface 12, so from going out
Smooth surface 13 just can guarantee function of infrared remote control it can directly be seen that infrared receiving terminal 23 in this way.
Specifically, light guide 1 is made of PC, light diffusing agent and color masterbatch or light guide is by PMMA, light diffusing agent and color masterbatch system
At.Light diffusing agent (i.e. silicone molecules material) is a kind of molecule, when light is irradiated to the light guide 1 containing light diffusing agent
When, light can repeatedly be reflected by the surface of light diffusing agent, be equivalent to and be formed with multiple light sources in light guide 1, in turn
So that the surface (i.e. light-emitting surface 13) of light guide 1 shines uniformly.Preferably, the ratio of PC, light diffusing agent and color masterbatch is 1000:
(0.6-1): the ratio of (0.4-0.7) or PMMA, light diffusing agent and color masterbatch are 1000:(0.6-1): (0.4-0.7), wherein color
Mother is preferably dark brown toner, is shone uniform effect to further reach product surface.
The utility model additionally provides a kind of television set, which includes above-mentioned light guide module.By using above-mentioned
Light guide module, the television set is under the premise of ensuring that 1 surface light emitting of light guide is uniform, it is ensured that the function of infrared remote control；Not only
It is limited to the limitation of 1 volume size of light guide, greatly reduces the cost of light guide 1 itself, it is beautiful to also ensure that light guide 1 shines
Property.
Obviously, the above embodiments of the present invention is used for the purpose of clearly illustrating examples for clearly illustrating the present invention, and
It is not limitations of the embodiments of the present invention.For the ordinary skill user of fields, in above description
On the basis of can also make other variations or changes in different ways.There is no need and unable to give all embodiments
Exhaustion.Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention etc., should be included in
Within the protection scope of the utility model claims.
