Description

Flat panel light with side light source

A flat panel light with a lateral light source, especially a flat panel light suitable for hanging lamps and having a larger illumination angle to facilitate illumination.

According to the conventional flat lamp, when it is installed in a building, it is installed by means of embedding or hanging. When the hanging flat lamp is suspended from the ceiling, since the flat lamp has only one-way light source, it can only be single. The illumination of the direction makes the illumination angle of the panel light limited, so the illumination brightness is also limited. If this problem is solved, multiple flat panel lamps must be installed to increase the illumination brightness of the entire use space, but more than the flat panel light The installation will increase the installation cost. Therefore, how to solve the problem of insufficient illumination angle above, and then increase the illumination angle of the panel light is the subject of research and development that the relevant industry is eager to develop.

The purpose of this creation is to install two sets of light source modules at the same time, and set the two to different projection directions to expand the illumination angle and prevent the illumination dead angle, which is beneficial to enhance the illumination.

In order to achieve the above objective, the panel lamp with a lateral light source comprises a plurality of side frames, a light guide plate, a first light source module and a second light source module, wherein the plurality of side frames are connected to each other to form a closed frame, and each side frame has a base portion, the side frame is formed on the two sides of the base portion, the first surface and the second surface are formed, the first surface is located inside the frame body, the second surface is located outside the frame body, and the second surface is extended from the base portion by the card portion, the light guide plate Installed in a frame formed by each side frame, the first light source module is disposed at the first side of the side frame And forming a locking state, the first light source module is opposite to the side of the light guide plate, the second light source module is disposed at the second side of the side frame, and the second surface is covered with a transparent cover, the transparent cover The two sides are clamped on the latching portion of the side frame and are used for stopping the positioning of the second light source module.

In the foregoing flat panel lamp, the frame of each side extends from the base portion toward the light guide plate, and the frame surface formed by each side frame is covered with a back plate, and the light guide plate is formed by clamping the back plate and the stop piece. .

In the foregoing flat panel lamp, the stopping piece of the side frame is disposed with a sliding slot near the first surface, and the side of the first light source module is formed in the sliding slot of the side frame to form a limit.

In the foregoing flat panel lamp, a filler member for filling the gap is disposed between the back plate and the stopper piece.

According to the above, when the first light source module and the second light source module are simultaneously illuminated, the direct light projected by the first light source module cooperates with the lateral light projected by the second light source module to generate A larger illumination angle to reduce the blind angle of illumination helps to improve illumination.

The fifth picture is a schematic diagram of the state of use of the creation.

Referring to the first to fourth figures, the panel lamp with the lateral light source comprises a plurality of side frames 1, a light guide plate 2, a first light source module 3, a second light source module 4 and a transmissive cover 5, wherein: The frame 1 of each side is connected to each other to form a closed frame, and each side frame 1 The base 11 has a first surface 111 and a second surface 112 formed on the two sides of the base 11. The first surface 111 is located inside the frame, the second surface 112 is located outside the frame, and the base 11 is provided with a positioning hole 113. Each side frame 1 is located at the first surface 111 and has a stopper piece 12. The stopper piece 12 is recessed with a sliding groove 121 near the first surface 111. The side frame 1 is located on the second side 112 and extends from the base 11 on both sides. The ejector portion 13 is disposed between the two adjacent side frames 1 , and the two sides of the frame connecting member 7 respectively penetrate into the positioning holes 113 of the adjacent side frames 1 to form a positioning, and the framed parts are The slats 8 are screwed at 7 to form a fixed positioning, so that each side frame 1 is connected to each other by the frame members 7 to form a closed frame.

The light guide plate 2 is attached to a frame formed by each of the side frames 1.

The first light source module 3 is disposed between the light guide group 2 and the side frame 1 , and faces the side of the light guide plate 2 , and the first light source module 3 is connected to the first surface 111 of each side frame 1 , and The side of the first light source module 3 is formed in the slot 121 of the side frame 1 to form a limit, and the first light source module 3 and the base 11 form a locking state; wherein, in the preferred embodiment, the screw lock is used. The first light source module 3 and the side frame 1 are fixed, and the first light source module 3 is abutted against the surface of the side frame 1 to directly transfer heat energy to the side frame 1 to improve heat dissipation efficiency.

The second light source module 4 is disposed at the second surface 112 of each side frame 1 .

The two ends of the transparent cover 5 are provided with a latching groove 51, and a stopper piece 52 is extended on one side of each of the latching grooves 51. When the transparent cover 5 is covered on the second surface 112 of the side frame 1, the transparent cover 5 is transparent. The card slot 51 of the two ends of the photomask 5 is positioned on the two latching portions 13 of the side frame 1 , and the oppositely disposed stop tabs 52 of the transmissive cover 5 can stop the second light source module 4 . .
