Problems solved by technology

At present, the classroom lighting environment is relatively severe, and suitable blackboard lights are generally not used, which makes the blackboard lighting in the classroom have problems such as illuminance and uniformity, finger display, stroboscopic and glare. Teenagers who are in such an environment for a long time will easily cause vision problems. Fatigue, which can eventually lead to nearsightedness
[0003] In addition, most of the existing blackboard lights need to be customized and installed according to environmental conditions such as the size, height, and location of the blackboard, and once the construction is completed, there is no room for adjustment, which causes great inconvenience

Embodiment 1

[0035] Such as figure 1 and figure 2 As shown, this embodiment proposes a classroom blackboard lamp with an adjustable light distribution curve, which includes a housing 1 , a lamp frame support ring stopper 3 , a lamp frame support ring 4 , a rotating frame 5 , a lens 6 , and a light source 7 . The housing 1 is a hollow structure with openings at the bottom and the front. The inner side (top and rear) of the housing 1 is a paraboloid. The light source 7 is located between the rotating frame 5 and the lens 6. The inner curved surface of the housing 1 receives the light source 7 and the lens 6. After the light is reflected, parallel light is emitted, which maximizes light utilization, reduces light waste, makes light distribution more uniform, and reduces the impact of glare.

[0036] Such as image 3 and Figure 4 As shown, the side cover 2 is an irregular quadrilateral structure with one side being a curve consistent with the cross section of the housing 1. It can be fixe...

Abstract

The invention relates to the technical field of indoor lighting, in particular to a classroom blackboard lamp with an adjustable light distribution curve. The classroom blackboard lamp comprises a shell (1) with a light transmission window or an open slot and two or more than two rotatable lamp brackets arranged in the shell (1) in parallel; by adjusting the rotation angle of therotatable lamp brackets, light emitted by a light source (7) is projected by the lens (6) and reflected by the shell (1), and emergent light from the light transmission window or the open slot is concentrated or diffused within a certain angle, so that a new light distribution curve is formed. The adaptability of the classroom blackboard lamp to blackboards of different specifications is improved.

Description

technical field [0001] The invention relates to the technical field of indoor lighting, in particular to a classroom blackboard lamp with an adjustable light distribution curve. Background technique [0002] Adolescent health is one of the issues related to the future of the country and the nation. It is imminent to prevent and control the visual health of children and adolescents. An important factor affecting the visual health of adolescents comes from the classroom lighting environment. At present, the classroom lighting environment is relatively severe, and suitable blackboard lights are generally not used, which makes the blackboard lighting in the classroom have problems such as illuminance and uniformity, finger display, stroboscopic and glare. Teenagers who are in such an environment for a long time will easily cause vision problems. Fatigue, which eventually leads to myopia. [0003] In addition, most of the existing blackboard lights need to be customized and inst...
