Description

Flat light fixture

This creation relates to a flat-panel luminaire, especially a flat-panel luminaire in which a diffused lampshade is arranged in a separate area to form a uniform light.

In indoor spaces such as homes, companies, or shopping malls, it is common to set up LED panel lights as the main source of lighting. LED panel lights mainly use light-emitting diodes (Light Emitting Diode) as the lighting source to create a bright and open space. .

According to the light emitting position of the LED, the LED panel light can be divided into a side-entry type or a direct-light type. Among them, the direct-type LED flat light adopts the light emission method that directly penetrates the diffuser plate and irradiates the light outward. In terms of the side-in light emitting method in which the light plate transmits the light to the diffuser plate, the direct-lit LED flat light can effectively exert the luminous efficiency of the LED. Moreover, compared with the side-entry type, the direct-lit LED flat light can eliminate the need and structure of installing a light guide plate. Therefore, the direct-lit LED flat light should have an advantage in overall installation cost or weight.

The LED panel light is mainly equipped with multiple LEDs to provide light, and each LED outputs a point light source. If the light equalization effect is not good, the lighting of the lamp will appear uneven, bright in the middle, dark on both sides, bright light bands at the light entrance, and visible parts Dark areas or inconsistent brightness at different angles, etc., these lack of illumination will directly affect the user's visual experience. If you stay in a poorly illuminated space for a long time, users are prone to discomfort, and the eyes are also prone to fatigue or a sense of soreness. In view of this, the creator of this case believes that it is necessary to conceive an LED panel light that can homogenize the light, so as to enhance the brightness of the overall space and provide users with a comfortable and soft uniform light.

The lamp holder includes a back plate and a side wall arranged on the outer periphery of the back plate, and the back plate and the side wall form an accommodating space. The light bar is arranged in the accommodating space of the lamp holder, and the light bar includes a circuit board arranged on the back plate and a plurality of LED lamp beads arranged on the circuit board. The outer frame is combined with the lamp holder, the outer frame has a plurality of partitioned areas, each of the partitioned areas is provided with a diffuser lampshade, and each diffuser lampshade corresponds to the LED lamp bead on the lamp holder The setting location.

Further, the diffuser lampshade has a uniform light effect.

Further, the plurality of separated regions are arranged on the outer frame to form a matrix arrangement.

Further, each diffuser lampshade corresponds to the installation position of the four LED lamp beads.

Further, the four LED lamp beads are arranged in a matrix on the circuit board.

Further, the outer frame includes a frame body with a locking groove, and a reflector plate disposed on the frame body and having the plurality of partition areas.

Furthermore, each of the partitioned areas is composed of four light-reflecting surfaces to form a light-transmitting opening, and the diffusing lampshade is arranged on the light-transmitting opening.

Further, a locking plate is provided on the outer periphery of the side wall, and a plurality of through holes corresponding to the locking groove are provided on the locking plate.

Further, an installation slot for the light bar is arranged in the back plate.

Further, the flat panel lamp further includes a power switch device, and the power switch device includes at least one wire electrically connected to the plurality of light bars, and a driver electrically connected to the wire.
