Detailed Description

The preferred embodiments of the present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, the classroom panel lamp 10 according to the present invention is a square frame structure, and is specifically configured in a square shape. The square frame structure of the classroom panel lamp 10 includes an upper cover plate 11, two left and right side plates 12, a rear side plate 16, a front side plate 13, and a bottom side plate 141. The upper cover plate 11, the left and right side plates 12, the rear side plate 16, the front side plate 13 and the bottom side plate 141 are assembled to enclose a light source cavity 19. A light source 17 for illumination and an electrical controller 18 for controlling the power on or off of the light source 17 are arranged in the light source chamber 19.

The bottom side plate 141 includes a bottom transparent plate 14 and a reflective plate 15, and the bottom transparent plate 14 and the reflective plate 15 are fixedly connected through a side edge, such as welding, bonding, clamping or integral forming. The bottom light-transmitting plate 14 is parallel to the ground, and the angle range of the included angle alpha formed between the bottom light-transmitting plate 14 and the bottom light-reflecting plate 15 is 120-150 degrees, and the preferred included angle is 135 degrees; wherein, the bottom light-transmitting plate 14 is a light-transmitting plate, and can be an acrylic plate, a PC plate, a glass plate, etc.; the bottom reflector 15 is a single light reflecting surface with a nearly specular reflection, and the light reflecting surface is located inside the light source cavity 19 and can emit the light emitted from the light source 17 in the light source cavity 19 through the bottom reflector 15. The bottom light-transmitting plate 14 and the bottom light-reflecting plate 15 are movably connected in a relatively rotatable manner, such as pivot connection, hinge connection and the like, and the size of an included angle between the bottom light-transmitting plate 14 and the bottom light-reflecting plate 15 can be adjusted according to needs by using the connecting structure, so that light emitted after being reflected by the bottom light-reflecting plate 15 is projected onto a blackboard conveniently, and the optimal illumination effect is achieved. Meanwhile, the front side plate 13 is designed as a front transparent plate, and the front transparent plate 13 is fixedly connected with the other side edge of the bottom light reflecting plate 15. By the design, part of light of the light source 17 can be directly emitted in the direction a through the bottom light-transmitting plate 14, and the student can read books and read for illumination; the other part of the light is reflected by the bottom reflector 15 and then emitted from the front side plate 13 according to the direction b, so as to illuminate the blackboard.

Preferably, the light source 17 is an LED light bar or an LED lamp tube. The number of the LED light bars is at least two, the LED light bars are transversely arranged above the bottom light-transmitting plate 14, and the distance between the LED light bars and the bottom light-transmitting plate 14 is kept at 2-5 cm; by the design, ventilation and heat dissipation of the lamp strip can be guaranteed, light can be emitted out through the front light-transmitting plate 13 at a better horizontal position, and lighting brightness and light color uniformity of the blackboard are guaranteed.

In order to make the light of the LED lamp irradiate the blackboard and/or the classroom floor space as much as possible, the rear side plate 16 of the square frame structure is designed as a light reflecting plate, i.e., a rear light reflecting plate 16, which can reflect part of the light through a diffuse reflection process and then emit the reflected light through the bottom light transmitting plate 14 and/or the front light transmitting plate 13, thereby improving the light utilization rate. The rear reflector 16 may be a mirror or a reflective film.

In an embodiment, the bottom transparent plate and the front transparent plate are made of the same material and have different specifications, and now the structure of the bottom transparent plate 14 is taken as an example to be described in detail.

As shown in fig. 3, the bottom transparent plate 14 includes an anti-glare diffusion layer 141, a blue light reduction layer 142, and a bead light diffusion layer 143 from top to bottom. The anti-glare diffusion layer 141 is made of an anti-glare rhombohedral crystal light-transmitting PMMA (polymethyl methacrylate) material. The glare effect of lamplight can be reduced or eliminated; the blue light reducing layer 142 is made of a composite material of PC and organic silicon resin spherical micro powder, so that harmful blue light can be filtered, eyes of people are protected, and discomfort of eyes to illumination is reduced; the pearly-lustre diffusion layer 143 is made of steel powder and PMMA through compounding, and after the steel powder forms austenite crystals, the pearly-lustre diffusion layer has a good diffusion effect on light and can resist high temperature. Therefore, the light-transmitting plate with the structure has strong light-emitting uniformity, anti-dazzle and blue light-reducing effects and is high-temperature resistant.

The arrangement of the front light-transmitting plate 13 may also be the same as the arrangement of the layer structure of the bottom light-transmitting plate 14, and will not be described herein again.

It should be understood that the above description is illustrative of the preferred embodiment of the present invention and is not to be construed as limiting the scope of the utility model, which is defined by the appended claims.
