Detailed Description

In order to clearly illustrate the technical features of the present invention, the present invention is explained in detail by the following embodiments with reference to the accompanying drawings.

As shown in fig. 1-2, a classroom lamp comprises a lampshade, an LED lamp bead 5 and a dimmer 7;

above-mentioned lamp shade includes lamp shade 1 and lower lamp shade 2, go up lamp shade 1 and lower lamp shade 2 between the joint, the mode through the joint is convenient for separate lamp shade 1 and lower lamp shade 2 like this, be convenient for change LED lamp pearl 5, lower lamp shade 2 adopts the glass lamp shade that has a plurality of concave lens 12 structures, concave lens 12 structure that sets up like this can increase the irradiation area on the one hand, on the other hand can also avoid light directly to shine, make light softer, avoid amazing eyes.

In other preferred embodiments, the upper lampshade 1 and the lower lampshade 2 can be connected through bolts, the bolts are detached when the LED lamp beads 5 are replaced, the upper lampshade 1 is separated from the lower lampshade 2, and after the replacement is completed, the upper lampshade 1 and the lower lampshade 2 are screwed down through the bolts to achieve connection.

Further, still be equipped with backplate 6, light guide plate 4 and card paper 11 in last lamp shade 1, should go up lamp shade 1 and adopt hollow structure, can alleviate the weight of whole lamp shade 1 like this, but also can practice thrift use material, reduce cost. Backplate 6 bonds in last lamp shade 1, and backplate 6 is located the below of LED lamp pearl 5, and this backplate 6 adopts the plastic-aluminum board, and LED lamp pearl 5 can be sealed on one side to one of them, can also assist the heat dissipation in addition. Still bond through glue in last lamp shade 1 and have light guide plate 4, this light guide plate 4 is located LED lamp pearl 5's top, still bonds card paper 11 at the upper surface of light guide plate 4, and light that light guide plate 4 can send LED lamp pearl 5 makes light evenly derive from the front through the site refraction, and card paper 11 can go out the afterglow reflection at the light guide plate 4 back in order to improve the light efficiency.
