Description

Adjustable double-sided lighting fixture

The invention relates to a lighting fixture, in particular to an adjustable double-sided lighting fixture with high degree of freedom and which can adjust the projection light type according to requirements.

At present, the types of lighting fixtures using LEDs are becoming more diverse with the changes in demand and lifestyle. In addition to the traditional one-way LED lamps, there are also lamps with double-sided lighting. The luminaires are generally suspended in an indoor space and are illuminated upwards and downwards through the light guide plates to achieve aesthetic and illumination purposes.

In order to adjust the ratio of the light output on both sides, it is common practice to apply a metal film on one surface of the light guide plate by vapor deposition to adjust the light intensity. However, for large-area light guide plates, this method will greatly increase the production cost, and the metal film will absorb the light energy and cause optical loss.

In order to solve the above-mentioned difficulty in dimming the double-sided lighting fixture, a manufacturer adopts a reflection structure at one of the light-emitting surfaces of the corresponding light-guiding plate to adjust the amount of light, and compared with the structural setting of the metallized film. Through the reflective structure, the amount of light emitted from both sides of the lamp can be adjusted while reducing the optical loss, and the manufacturing cost is also low. In detail, the reflective structure is fixed to the lamp frame and includes at least two transparent sheets spaced apart from each other by at least one air layer to reflect part of the light emitted from the corresponding light exit surface back into the light guide plate, and is opposed by Another light surface is emitted, as described in the Republic of China Patent Publication No. 201500682. However, the reflection structure corresponds to The overall size of the light-emitting surface is set to form a completely covered surface, and the reflective structure is fixed to the frame of the lamp and cannot be moved arbitrarily. Therefore, the structure of the lamp cannot change the light-emitting state of the lamp at any time according to the user's needs. There are many inconveniences in the application.
