Problems solved by technology

However, if this method is used on a large-area transparent board, it will cost a lot of production costs, which is not economical for the industry.
Furthermore, after the metal film is coated on the surface of the transparent plate, it will absorb at least 10% of the luminous flux, resulting in optical loss

Embodiment Construction

[0024] Please refer to figure 1 and figure 2 , which respectively depict a three-dimensional schematic diagram and a partial schematic diagram of a lamp according to an embodiment of the present invention. In this embodiment, the lamp 100 mainly includes a frame 120 , a light guide plate 140 , a light source 160 and a reflection structure 180 . The light guide plate 140 and the reflective structure 180 are erected in the frame 120 in a parallel manner. Wherein, the light guide plate 140 has two light-emitting surfaces, and the reflective structure 180 is adjacent to one of the light-emitting surfaces. The reflective structure 180 is mainly used to adjust the light output of the two light emitting surfaces of the light guide plate 140 .

[0025] Please also refer to figure 2 and image 3 ,in image 3 It is a schematic diagram showing the internal structure of a lamp according to an embodiment of the present invention. The light guide plate 140 is disposed in the frame ...

Abstract

The invention discloses a lamp which comprises a frame, a light guide plate, a light source and a reflection structure. The light guide plate is arranged in the frame and comprises a light incoming face, a first light outgoing face and a second light outgoing face. The second light outgoing face is opposite to the first light outgoing face, and the light incoming face is connected with the first light outgoing face and the second light outgoing face. The light source is arranged nearby the light incoming face and in the frame. The reflection structure is adjacent to the first light outgoing face and comprises at least two transparent sheets. The at least two transparent sheets are separated by at least one air layer, so that at least one light ray emitted from the first light outgoing face is reflected back to the light guide plate and emitted through the second light outgoing face.

Description

technical field [0001] The present invention relates to a light emitting device, and in particular to a lamp capable of emitting light from both sides. Background technique [0002] In response to the needs of the market, the changes in lamps are becoming more and more diverse. There is a kind of hanging transparent lamp, which can emit light towards the ceiling and the ground at the same time, so as to achieve the purpose of beauty and lighting. In addition, due to actual usage conditions, the amount of light emitted downward is generally greater than the amount of emitted light upward. [0003] In order to adjust the ratio of the amount of light emitted upwards and downwards, a common method is to use evaporation to coat a metal film on the surface of another transparent plate of the lamp. However, if this method is used on a large-area transparent board, a lot of production costs must be spent, which is not economical for the industry. Furthermore, after the metal film...
