Embodiment 1

[0051] The first embodiment of the present invention provides a lighting device, figure 2 is a schematic diagram of the overall structure of the lighting device according to the first embodiment of the present invention, image 3 It is a schematic diagram of the partial structure of the lighting device according to the first embodiment of the present invention. refer to Figure 2-Figure 3 As shown, the lighting device A provided in this embodiment is installed on the lighting device installation part, and includes two light guide plates 1. The light guide plates 1 respectively have a light incident surface 11 and a plurality of light output surfaces 12. The first light-emitting surface 121 of the device mounting part is far away from the second light-emitting surface 122 of the lighting device mounting part, the side light-emitting surface 12a connecting the first light-emitting surface 121 and the second light-emitting surface 122, the first light-emitting surface 121 and t...

Embodiment 2

[0059] The second embodiment of the present invention provides a lighting device, Figure 5 It is a schematic diagram of the overall structure of the lighting device 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, refer to Figure 5 As shown, the lighting device A also includes a light outlet 5 arranged between the two light guide plates 1. The light outlet 5 is roughly rectangular in shape, equivalent to the light guide plate 1 in the length direction, and connected to the fixed bracket 2, while maintaining the lighting device symmetrical design.

[0060] The light exit part includes an LED chip group, the LED chip group is arranged on the fixed bracket along the length direction of the light exit part 5, and the plurality of LED chips 31 installed on it are arranged in a direction away from the lighting device ...

Embodiment 3

[0062] The third embodiment of the present invention provides a lighting device, Figure 6 It is a schematic diagram of the partial structure of the lighting device according to the third embodiment of the present invention. The third embodiment is a further improvement on the first embodiment and the second embodiment, the main improvement is that in the third embodiment of the present invention, refer to Figure 6As shown, the third light-emitting surface 123 is a slope, and the angle between the slope and the first light-emitting surface 121 is smaller than the angle between the slope and the second light-emitting surface 122 .

[0063] A part of the light entering the light guide plate 1 is diffusely reflected by the optical point and exits from the first light exit surface 121, the second light exit surface 122, and the side light exit surface 12a to form a light emitting surface light source. At the same time, the light entering the light guide plate 1 is There is a par...

Abstract

The invention relates to the field of lighting, in particular to a lighting device with light guiding plates. The lighting device is mounted on a lighting device mounting part and comprises the two ormore light guiding plates, a fixing bracket, two or more LED chip mounting parts and optical points; each light guiding plate is provided with a light entering face and a plurality of light exiting faces, the two or more light guiding plates are placed in the same plane, and the light entering faces of the light guiding plates are oppositely arranged or placed in the same plane; the fixing bracket is connected with the light guiding plates in a combined mode and connected with the lighting device mounting part; the two or more LED chip mounting parts correspond to the light entering faces ofall the light guiding plates correspondingly, and are arranged on the fixing bracket in the mode that a plurality of LED chips mounted on the LED chip mounting parts face the light entering faces; andthe optical points are arranged on the first light exiting faces or the second light exiting faces and reflect parts of light rays entering the light guiding plates by the LED chips to the light exiting faces, wherein the light flux in the direction of one sides of the first light exiting faces of the light guiding plates is different from the light flux in the direction of one sides of the second light exiting faces of the light guiding plates.

Description

technical field [0001] The invention relates to the field of lighting, in particular to a lighting device using a light guide plate. Background technique [0002] LED (Light Emitting Diode, Light Emitting Diode) is a semiconductor device capable of converting electrical energy into visible light. LED lighting products are semiconductor solid light emitting devices. It uses a solid semiconductor chip LED as a light-emitting material. In the semiconductor, excess energy is released through the recombination of carriers in the semiconductor to cause photon emission, and directly emit red, yellow, blue, green, blue, orange, purple, and white light. LED lighting device is an emerging industry developed in recent years, which only needs a very small current to excite light with a relatively high brightness. [0003] With the popularization of LED lighting products, simple basic lighting can no longer meet people's needs. LED lamps with uniform light emission, unique shape and st...
