Specific implementation mode

To further illustrate that each embodiment, the utility model are provided with attached drawing.These attached drawings are in the utility model discloses A part for appearance mainly to illustrate embodiment, and can coordinate the associated description of specification to explain that the running of embodiment is former Reason.Cooperation refers to these contents, and those of ordinary skill in the art will be understood that other possible embodiments and this practicality are new The advantages of type.Component in figure is not necessarily to scale, and similar component symbol is conventionally used to indicate similar component.

The utility model is further illustrated in conjunction with the drawings and specific embodiments.

As shown in Figure 1-Figure 3, the utility model provides a kind of LED classroom lamps, including outer housing 1, light fixture 2 and lattice Screen 3, the outer housing 1 have a cavity 10, and the opening of cavity 10 is light-emitting window, and the light fixture 2 is mounted on outer housing 1 It is interior, and the light that light fixture 2 is emitted is emitted from the light-emitting window of outer housing 1, and the flase floor 3 is fixedly mounted on outer housing 1 Light-emitting window at, hole on the flase floor 3 is in cellular.The light that light fixture 2 is emitted is by cellular on flase floor 3 Hole diffusion so that light be in a branch of beam outgoing, uniform intensity is emitted so that light is not required to by diffuser plate Diffusion can also reach dazzle, the requirement of illumination and illumination average value.

As a preferred embodiment of flase floor 3, the aperture of the hole on flase floor 3 is from light inlet toward light-emitting window direction Gradually increase.This similar bell-mouthed shape not only contributes to the diffusion of light, but also convenient for laggard in grid sheet metal forming Row stripping operation.

With reference to figure 3 and Fig. 4, as a preferred embodiment of the present embodiment, the cavity bottom of the outer housing 1 has At least a boss 12, the top surface of the boss 12 are a flat surface, and the light fixture 2 includes LED light source board 20, lampshade 22 and drives Dynamic device 24, the LED light source board 20 are welded with plurality of LEDs light source, and the LED light source board 20 is directly fixedly mounted on boss 12 On top surface, the lampshade 22 covers LED light source board 20, since LED light source board 20 is directly anchored on boss 12, i.e., directly It connects and is fixed on outer housing 1, not only save the cost of radiating piece, and entire radiating piece of the outer housing 1 as light fixture, Also has good heat dissipation effect.It is typically all to be stamped to form by proximate matter, therefore boss 12 can be direct additionally, due to outer housing 1 By outer housing 1 together punch forming.
