704 with clip in the fixing hole 110 of pedestal 100, and pedestal 100 can be attached to by an at least locking accessory (such as screw) 706.
The illuminating mouse pad 10 of the utility model with the light guide plate 520 of light-reflecting portion 570 to avoid spot light 514 from sending
Light directly project light guide plate 520, user can be effectively prevented from and produced the problem of exiting surface 532 observes directly bright spot
It is raw.
To be illustrated herein, the luminescence unit 510 in the illuminating mouse pad 10 of the utility model is not limited to
Only send the light of solid color；In other words, in illuminating mouse pad 10 of the present utility model, luminescence unit 510 can send many
The light of color is planted, therefore its single spot light 514 can be the light emitting diode with feux rouges, green glow and blue chip.Driving electricity
Road 518 can individually drive feux rouges, green glow and blue chip luminous, or at least two in driving feux rouges, green glow and blue chip
Person lights, multifarious photochromic to provide by mixed light.In order to improve light mixing effect, the incidence surface of light guide plate 520 can be through design
And with micro-structural, for example, can be the zigzag micro-structural shown in Fig. 7.
Secondly, in order to avoid providing the uniformity of the light by the outgoing of light out part 530, exiting surface 532 may be machined and have
There is zigzag texture as shown in Figure 8.Also, in order to avoid there is local bright spot in exiting surface, and increase the lighting area of light,
Reflective surface 572 can be processed and had as shown in Figure 9 on the premise of not influenceing reflective surface 572 to provide total reflection effect
Zigzag texture.
Figure 10 is referred to, it is the sectional view of the light source module of the embodiment of the utility model the 5th.In Fig. 10, light source
Module 500 includes the plural light guide plate 520 of spot light 514 and one, light guide plate 520 have a light out part 530, a light in part 550 and
One light-reflecting portion 570, the connection light out part 530 of light-reflecting portion 570 and light in part 550, and with a reflective surface 572 and a refractive power face 574,
Reflective surface 572 faces incidence surface 566, and refractive power face 574 faces exiting surface 532.Spot light 514 is arranged on incidence surface 566, spot light
514 light sent by incidence surface 566 enter light guide plate 520 light in part 550, and through reflective surface 572 reflect after be transferred to it is scattered
Face 574 is penetrated, enters light out part 530 after being reflected through reflective surface 578, and by the outgoing of exiting surface 532.
In Fig. 10, it may be machined on refractive power face 574 and shape is serrated texture, use expansion by the outgoing of exiting surface 532
Light angle, and local bright spot (hot spot) generation can be avoided.
Although the utility model is disclosed above with embodiment, so it is not limited to the utility model, any ripe
