Problems solved by technology

This device can solve the shadow problem to a certain extent, but it is limited by the relative positional relationship between the light source and the light guide assembly, which leads to an increase in the size of the light guide assembly and limits the multiple utilization methods of the light guide plate itself

Embodiment 1

[0075] The first embodiment of the present invention provides a light guide assembly, figure 1 is a schematic perspective view of the light guide assembly of the first embodiment of the present invention, figure 2 is true figure 1 An enlarged partial top view of the light guide assembly in the area of ​​the light guide plate where the central opening 4 is located and the corresponding LED chip mounting portion 3 . see Figure 1-Figure 2 As shown, the light guide assembly A includes a light guide plate 1 and an LED chip mounting portion 3. The light guide plate 1 is made of a material with good light transmittance, and has a light incident surface 11 and a light exit surface 12. The light exit surface 12 includes first parallel to each other. The light emitting surface 12a and the second light emitting surface 12b, wherein the first light emitting surface 12a and the light incident surface 11 are perpendicular to each other, and the second light emitting surface 12b and the ...

Embodiment 2

[0083] The second embodiment of the present invention provides a light guide assembly, image 3 It is a partial top view of the light guide assembly according to the second embodiment of the present invention, Figure 4 It is a schematic diagram of the partial structure of the light source of the light guide assembly according to the second embodiment of the present invention. The second embodiment is a further improvement on the first embodiment, the main improvement is that in the second embodiment of the present invention, image 3 is true figure 1 A partial top view of the enlarged light guide assembly A of the local area of ​​the light guide plate 1 where the middle opening 4 is located and its corresponding LED chipset 3, as shown in image 3 As shown, according to the position of the non-light-emitting region 32, the light-emitting region of the LED chip is divided into a second light-emitting region 312 adjacent to the non-light-emitting region 32 and located on both...

Embodiment 3

[0089] A third embodiment of the present invention provides a light guide assembly. Figure 5 It is a schematic diagram of the partial structure of the light source of the light guide assembly according to the third embodiment of the present invention. The third embodiment is an improvement on the use of two-color LED chips 3a for dimming lighting in the second embodiment. The edges of 1 are arranged in two rows in parallel, and the LED chips 3 a have two different colors of white and yellow, and the two-color LED chips 3 a are evenly arranged in the light emitting area 31 .

[0090] The single-side arrangement before using the double-color LED chip 3a is improved, such as Figure 5 As shown in the single column on the left or the single column on the right (here the single column on the right is used as an example to describe), there is a yellow LED chip b' between the two white LED chips LED chip a' and LED chip c', that is, the yellow and white chips are arranged alternate...

Abstract

The invention relates to the field of lamp illumination, and discloses a light guide assembly and an illumination device using the light guide assembly. The light guide assembly comprises a light guide plate, an LED chip mounting part and opening holes, wherein the light guide plate is provided with an incidence surface and an emergent surface; the LED chip mounting part is arranged so as to correspond to the incidence surface, and a plurality of LED chips mounted on the LED chip mounting part are arranged in a manner of facing the incidence surface; and the opening holes are formed in the edge of the same side, corresponding to the LED chip mounting part, of the light guide plate, and penetrate through the light guide plate. The emergent surface comprises a first emergent surface and a second emergent surface which are parallel to each other, and the first emergent surface and the incidence surface are perpendicular to each other, and the second emergent surface and the incidence surface are perpendicular to each other; and the LED chip mounting part comprises an LED chip light emitting area provided with the plurality of LED chips, and a non-light-emitting area which is not provided with the LED chips, and the non-light-emitting area is arranged corresponding to the opening holes. According to the light guide assembly and the illumination device using the light guide assembly, the problem of light guide plate shadow can be effectively solved, and the light emitting comfort degree of a lamp is improved.

Description

technical field [0001] The invention relates to the field of lamp lighting, in particular to a light guide assembly and an illumination device using the light guide assembly. Background technique [0002] The role of the light guide plate is to convert the line light source originally composed of LED particle point light sources into a surface light source. It is an important component in backlight lamps. At present, the side-light light guide plate has gradually become the mainstream. Its biggest advantages are thin thickness and light weight. ,low cost. However, since the light enters the light guide plate from the edge of the side-illuminated light guide plate, shadows will be produced by the installation and fixing components of the lamps and other functional supporting devices, which affects the appearance and comfort of light emission. [0003] To solve this problem, Patent Document 1 CN201010003969.6 discloses a light guide plate, a backlight module and a method for ...
