Problems solved by technology
Disadvantages are: the strong light emitted by the lamp tube can enter the human eyes, which is uncomfortable and the glare is very strong, and the human eyes are prone to fatigue
The disadvantages are: too many reflections, serious light loss, and low light efficiency
The disadvantage is: the lamp beads need to be distributed in a large area to make the light soft, and a large part of the light cannot be directly diffused, and the light efficiency is low
None of these three kinds of lamps can achieve both light energy utilization rate and anti-glare effect

The invention provides an LED panel lamp which can fully utilize light energy and also can prevent the visual fatigue. The LED panel lamp comprises a lamp disc bottom shell, LED lamp panels and a light reflecting panel, at least one long-strip-shaped radiator is arranged in the lamp disc bottom shell, the lamp disc bottom shell is in an opening box shape, the two ends of each radiator are fixedly connected with the side wall of the lamp disc bottom shell, and the LED lamp panels are fixed to the radiator. Beads on the LED lamp panel are away from the opening direction of the lamp disc bottom shell, and the section of the light reflecting panel comprises at least one circular arc. The sinking reflection face corresponding to each circular arc faces the opening direction of the lamp disc bottom shell, and is correspondingly provided with one radiator. The LED panel lamp has the beneficial effects that the LED lamp panels are away from the irradiation area, the irradiation area is lighted through diffuse reflection of the reflecting panel, the light rays are gentle, the light energy utilization rate of the reflecting panel is high, two sets of LED lamp panels are arranged to be combined with the reflecting panel, the LED lamp panels are overlaid in the weak light ray area, and are dispersed in the strong light ray area, and the illuminance is even.
Description
technical field [0001] The invention relates to the technical field of lighting, in particular to an LED panel lamp. Background technique [0002] In the current market, there are mainly three light distribution methods for LED flat panel lights: grille light type, side light type, and bottom light type. Grille lamp type panel light, the main light is direct light from the lamp tube, and the grille plates on both sides are used to reflect the stray light back. The advantage of this lamp is: high light efficiency. The disadvantage is: the strong light emitted by the lamp tube can enter the human eyes, the uncomfortable glare is very strong, and the human eyes are prone to fatigue. Side-emitting panel light, the lighting principle is: the light source is irradiated from the two sides or four sides of the light guide plate. After the light passes through the light guide plate, the light direction of the light will change, scattered upward, and then atomized by the diffuser pl...
