Embodiment Construction

[0018] Below in conjunction with accompanying drawing, the present invention will be further described as follows:

[0019] The invention provides an anti-glare installation method for classroom LED blackboard lamps. The LED blackboard lamps are installed above the front of the blackboard, and the installation position of the LED blackboard lamps satisfies the mathematical relationship m figure 2 . As a preference: the installation position of the LED blackboard lamp satisfies the mathematical relationship m<h+n+w-172, where 172 means that the average height of the teacher is 172 cm, and the units of m, h, n, and w in the formula are all centimeters, Here, it can also be customized according to the height of different teachers in different schools, which can be any value; the angle θ between the lower edge point of the LED blackboard lamp and the line connecting the human eye and the horizontal line satisfies π / 4<θ<π / 2 , so that the direct glare area can be avoided, thereby re...

Abstract

The invention belongs to the technical field of designing of classroom illumination light environments, and specifically relates to an anti-glare mounting method for a classroom LED blackboard lamp. The LED blackboard lamp is installed before and above a blackboard. The installation position of the LED blackboard lamps meets the mathematical relation that m < h + n + w - the height of a teacher, wherein m is the horizontal distance between the center of a light outlet surface of the blackboard lamp and a blackboard surface, n is the vertical distance between the center of the light outlet surface of the blackboard lamp and the upper edge of the blackboard, h is the vertical distance between the lower edge of the blackboard and a platform surface, and w is the width of the blackboard. Compared with the prior art, the invention has the following advantages: the anti-glare mounting method is designed based on a current classroom lighting environment, fills a blank in current methods for installing LED blackboard lamps in classrooms, can effectively reduce uncomfortable glare generated by the LED blackboard lamp to teachers while meeting the requirements for blackboard illumination andillumination uniformity, improves class quality and classroom efficiency for the teachers, and is worthy of application and promotion.

Description

[technical field] [0001] The invention relates to the technical field of classroom lighting environment design, in particular to an anti-glare installation method for classroom LED blackboard lamps. [Background technique] [0002] A reasonable classroom lighting environment is one of the indispensable auxiliary conditions for improving vision health. To this end, pilot projects for classroom lighting renovation have been launched one after another across the country. At the same time, the design of classroom lighting products and the design of classroom light environment have also attracted the attention of major manufacturers. The main difficulty in the transformation of the classroom light environment is the design and installation method of the blackboard lamp. From the classroom site, it can be seen that the main problem is that the glare to the teachers is too large, causing strong reactions from the teachers. Therefore, if we can provide an installation method that c...
