Correspondingly, the lamp provided by the embodiment of the application also has the advantages of being capable of relieving the problems of obvious darkness and brightness, poor illuminance uniformity and eyestrain of a user.

Optionally, in this embodiment, the lamp housing 100 is configured as an aluminum profile, so that on one hand, the lamp has a high heat dissipation effect, and on the other hand, the weight of the whole lamp can be reduced.

Optionally, in this embodiment, the light source 200 is an LED light source; alternatively, the light guide 300 is a plate-shaped light guide plate, but may be a lens.

In one embodiment, referring to fig. 4 and 5, the number of the mounting grooves 101 is three, and it can be understood that the number of the light source grooves 1011, the light guide grooves 1012 and the windows 1013 are three, and based on this, the number of the light source elements 200 and the light guide elements 300 is also three. For example, as shown in fig. 2 and 3, three light sources 200 are sequentially distributed along the vertical direction, and three light guides 300 are sequentially distributed along the vertical direction, so that, during operation, the upper light guide 300 can deflect the light emitted by the corresponding light source 200 to the lower area of the blackboard surface, the middle light guide 300 can deflect the light emitted by the corresponding light source 200 to the middle area of the blackboard surface, and the lower light guide 300 can deflect the light emitted by the corresponding light source 200 to the upper area of the blackboard surface, as shown in fig. 3; or, the light pipe 300 of top deflects light to the top region on blackboard surface, and middle light pipe 300 deflects light to the middle region on blackboard surface, and the light pipe 300 of below deflects light to the below region on blackboard surface, so can slow down the serious problem of the illumination from the top down gradual decay on blackboard surface, help making the whole illumination on blackboard surface have higher homogeneity, and then slow down the problem that the blackboard is dark bright obviously to lead to the user to use eyestrain.

In one embodiment, referring to fig. 2, 4 and 5, the light source grooves 1011 and the light guide grooves 1012 are sequentially distributed along the Y axis, and based on this, after the lamp housing 100 is applied to a lamp, the light source elements 200 and the light guide elements 300 are also sequentially distributed along the Y axis. So set up, light guide 300 can be used for setting up reflection paper, reflector panel isotructure along the other side of Z axle relative to window 1013, helps improving the light utilization ratio of lamp source 200 like this to help making the blackboard surface have higher illuminating effect.

In one embodiment, referring to fig. 2, fig. 4 and fig. 5, the window 1013 is located on one side of the light guide groove 1012 along the Z-axis, the other side of the light guide groove 1012 along the Z-axis opposite to the window 1013 is the installation side 102, and the installation side 102 is configured to allow the light guide 300 to be arranged along one side of the Z-axis and configured to be inclined downward. Specifically, as shown in fig. 2 and 3, one side of the light guide 300 along the Z-axis is exposed to the window 1013, and the light guide 300 is arranged along the installation side 102 along the other side of the Z-axis with respect to the window 1013, the light guide 300 is also provided obliquely downward with the installation side 102, so that the light guide 300 can deflect the light rays downward to better deflect the light rays to the blackboard surface.

It should be noted that the downward inclination angles of the at least two light guides 300 may be different, so that the at least two light guides 300 can deflect the light to different areas of the blackboard surface respectively; of course, the downward inclination angles of the at least two light guide members 300 can be the same, so that the microstructures on the surface of the light guide members 300 can be correspondingly arranged, so that the at least two light guide members 300 can deflect light rays to different areas on the surface of the blackboard respectively, and the requirement of the blackboard for uniform illumination is met.

In an embodiment, referring to fig. 2 to 5, the downward inclination angle of the mounting side 102 is an angle a, as shown in fig. 2, the angle a ranges from 10 ° to 15 °, and correspondingly, the downward inclination angle of the light guide 300 ranges from 10 ° to 15 °. So set up for each leaded light 300 all can deflect light to the blackboard surface better, and be unlikely to deflect light outside the blackboard, helps making the blackboard surface have better illuminating effect. The downward inclination angle of the mounting side 102 can be selected from 10 °, 11 °, 12 °, 13 °, 14 °, 15 °, etc., as long as it is in the range of 10 ° to 15 °.

In an embodiment, referring to fig. 2 and fig. 5, the housing 10 has at least two light blocking portions 12, the number of the light blocking portions 12 is the same as the number of the mounting grooves 101, that is, the number of the light blocking portions 12 is the same as the number of the light guide members 300 and the number of the light source members 200, and the at least two light blocking portions 12 and the at least two light guide members 300 are disposed in a one-to-one correspondence manner.
