Abstract

The invention relates to the technical field of lighting devices, in particular to an integrated LED blackboard lamp. The integrated LED blackboard lamp is characterized by comprising an integrated profile, an aluminum substrate and an LED array, wherein the integrated profile is a tubular aluminum profile; the aluminum substrate is fixedly fitted to the inner surface of the integrated profile; the LED array is welded on the aluminum substrate through SMD welding; the integrated profile further comprises an arc-shaped reflection cover extending from the upper front part towards the lower back part; light rays emitted by the LED array is subjected to diffuse reflection through the reflection cover and reaches a blackboard; the cross section of the reflection cover is a parabola; an included angle alpha between the symmetry axis of the parabola and the vertical central axial line of the integrated profile is greater than or equal to 20 degrees and less than or equal to 30 degrees, and a parabolic equation is y=x2 / 64; and the LED array is mounted on the focal point of the parabola. The integrated LED blackboard lamp is high in heat dissipation performance, long in service life and adjustable in angle and can light the blackboard area to the maximum extent and avoid the visual fatigue of a teacher due to direct light.

Description

technical field [0001] The invention relates to the technical field of lighting devices, in particular to an integrated LED blackboard lamp. Background technique [0002] Most of the blackboard lights used in schools now are as figure 1 As shown, the lamp tube (2') is installed on the lamp housing (1'), and the light is reflected to the blackboard through the reflector (3'). The problems of this type of blackboard lamp are: [0003] 1. The installation position of the blackboard lamp in the classroom is above the blackboard. Most of the light reflected by this structure reflector shines on the upper part of the blackboard and the wall above the blackboard, but there is not enough light in the blackboard area that really needs to be illuminated. As a result, the illuminance of the lower and upper parts of the blackboard is extremely uneven. [0004] 2. Since the blackboard light is installed above the head of the teacher, the direct light of the blackboard light with this s...
