Abstract
An LED blackboard is used for lighting a blackboard or a wall body and comprises an LED light source panel provided with an LED light source and a light shielding cover. The light shielding cover is of a shell structure, and the height of the light shielding cover is higher than that of the blackboard or the wall body to be lighted; one end of the light shielding cover is arranged at the periphery of the LED light source panel, a light outlet is formed in the other end of the light shielding cover, and the light outlet faces the blackboard or the wall body; the light shielding cover comprises an internal lateral plate close to one side of the blackboard or the wall body and an external lateral plate far from one side of the blackboard or the wall body; and the inner wall of the external lateral plate is used for reflecting light which emitted by the LED light source and under the blackboard or the wall body to the blackboard or the wall body. The LED blackboard lamp is high in light utilizing rate and can effectively avoid glare.
Description
Technical field
The present invention relates to field of LED illumination, particularly a kind of LED blackboard lights.
Background technology
The application of blackboard in education activities is very general, can be used for teacher's writing and teaching content.The applied environment of blackboard is very various, under the environment that some light is not good, blackboard lights can be used to increase the brightness of blackboard, if but the light that is irradiated on blackboard of blackboard lights is uneven, then can affect the visual condition of blackboard content, and easily cause the visual fatigue of beholder.For this situation, just require that blackboard lights will possess good installation site, irradiating angle and rational distribution of light mode, a reasonable blackboard lights or Lighting Design seem particularly important concerning blackboard.Traditional blackboard lights is generally use two fluorescent tubes, and blackboard lights is arranged on the position of blackboard oblique upper, its light sent has the eyes of part direct projection people, produce the eyesight of glare effects people, and it is far away below comparatively near above this blackboard lights distance blackboard, distance blackboard, blackboard surface illumination is from top to bottom decayed gradually, and the illumination mean value on blackboard surface is on the low side, this just makes existing blackboard lights there is the shortcoming that uniformity of illuminance difference, direction controllability are not strong and light utilization efficiency is lower.
Summary of the invention
In view of this, be necessary to provide a kind of light utilization ratio high and can the LED blackboard lights of effective anti-dazzle.
The technical solution used in the present invention is: a kind of LED blackboard lights, for irradiating blackboard or body of wall, comprise the LED light source plate and light shield that are provided with LED light source, this light shield is shell structure, the height that this light shield is arranged is higher than the height of blackboard to be illuminated or body of wall, one end of this light shield is arranged on this LED light source panel area, the other end of this light shield is light-emitting window, this light-emitting window is arranged towards this blackboard or body of wall, the outer panel that this light shield comprises the interior plate that arranges near the side of this blackboard or body of wall and arranges away from the side of this blackboard or body of wall, the inwall of this outer panel be used for towards this blackboard or body of wall reflect that described LED light source sends towards the light below this blackboard or body of wall.
Compared with prior art, this LED blackboard lights is provided with light shield especially, on the one hand, the outer panel of this light shield can by below this blackboard of script directive or body of wall, the light reflection that do not have illuminating effect on this blackboard or body of wall, improve the utilization ratio of light; On the other hand; the light-emitting window of this light shield is arranged towards this blackboard or body of wall; the light be positioned at when people stand on before this blackboard or body of wall below this LED blackboard lights can be blocked; these LED light sources send towards the light below this blackboard or body of wall after reflection according to desired position; prevent light direct projection human eye and produce dazzle, protective effect is served to human eye.
