Abstract
The utility model relates to an anti-dazzle blackboard lamp, which comprises a shell, a lamp body and an anti-dazzle device; the front side of the shell is provided with an opening, and the lamp body is arranged in the shell and irradiates light to the blackboard forwards through the opening; the anti-glare device is arranged in the shell and is used for reducing the glare on the transverse direction of the blackboard. The utility model has the advantages that: the glare on the blackboard in the transverse direction is controlled to be within a normal visual angle, and then the glare on the blackboard in the transverse direction can not directly irradiate eyes, so that the influence of the glare on the blackboard in the transverse direction on the sight of a teacher is prevented.
Description
Technical Field
The utility model relates to the field of lighting, concretely relates to anti-dazzle blackboard lamp.
Background
At present, requirements for blackboard lamps in classroom illumination only pay attention to light uniformity and direct glare on students in the vertical direction, and the blackboard lamps have the glare in the horizontal direction when a teacher writes or transversely observes, so that visual interference of the teacher in class teaching is caused finally. Because the teacher has glare transversely when writing or transversely observing, the development of the blackboard lamp which has glare protection on the teacher transversely ensures that the teacher can also obtain vision protection when writing or transversely observing is very important and has certain significance.
SUMMERY OF THE UTILITY MODEL
To sum up, for overcoming prior art's not enough, the utility model aims to solve the technical problem that an anti-dazzle blackboard lamp is provided.
The utility model provides an above-mentioned technical problem's technical scheme as follows: an anti-glare blackboard lamp comprises a shell, a lamp body and an anti-glare device; the front side of the shell is provided with an opening, and the lamp body is arranged in the shell and irradiates light to the blackboard forwards through the opening; the anti-glare device is arranged in the shell and is used for reducing the glare on the transverse direction of the blackboard.
The utility model has the advantages that: the glare on the blackboard in the transverse direction is controlled to be within a normal visual angle, and then the glare on the blackboard in the transverse direction can not directly irradiate eyes, so that the influence of the glare on the blackboard in the transverse direction on the sight of a teacher is prevented.
On the basis of the technical scheme, the utility model discloses can also do as follows the improvement:
further, the anti-glare device includes a lens and a grille cover; the lens is arranged in the shell and corresponds to the front of the lamp body; the grille cover is mounted in the opening.
The beneficial effect of adopting the further scheme is that: the glare in the transverse direction of the blackboard is controlled within a normal visual angle through the lens and the grille cover.
Further, the lamp body comprises a substrate and an LED lamp; the substrate is arranged in the shell, and the LED lamp is arranged on the substrate; the lens is arranged in the shell and corresponds to the front of the substrate, and a groove is formed in one side of the lens corresponding to the lamp body; the grooves are correspondingly positioned in front of the LED lamps.
Further, a connecting piece for hanging the shell to a corresponding position is fixed at the top of the shell.
The beneficial effect of adopting the further scheme is that: the installation of blackboard lamp is realized.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the drawings, the components represented by the respective reference numerals are listed below:
1. the LED lamp comprises a shell, 2, a lens, 3, a grating cover, 4, a groove, 5, a substrate, 6, an LED lamp, 7 and a connecting piece.
Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
As shown in fig. 1. An anti-dazzle blackboard lamp. Comprising a housing 1, a lamp body and an anti-glare device. The front side of the shell 1 is provided with an opening. The top of which is fixed with a connecting piece 7 for hanging it to a corresponding position. The lamp body is installed in the housing 1 and irradiates light forward toward the blackboard through the opening. The anti-glare device is installed in the housing 1 and is used to reduce glare in the lateral direction of the blackboard. The anti-glare device includes a lens 2 and a grille cover 3. The lens 2 is installed in the housing 1 and corresponds to the front of the lamp body. One side of the lamp body corresponding to the lamp body is provided with a groove 4. The grille cover 3 is mounted in the opening. The lamp body includes a substrate 5 and an LED lamp 6. The substrate 5 is mounted within the housing 1. The LED lamp 6 is mounted on the substrate 5. The lens 2 is installed in the housing 1 in front of the substrate 5. The groove 4 is positioned on one side of the lens 2 and corresponds to the front of the LED lamp 6.
The light rays irradiated by the LED lamp 6 sequentially pass through the lens 2 and the grille cover 3 and finally irradiate the blackboard. Under the action of the lens 2 and the grille cover 3, the transverse glare of light rays irradiated on the blackboard is reduced, and the transverse glare of the blackboard is controlled within a normal visual angle finally, so that the transverse glare of the blackboard cannot directly irradiate eyes, and the influence of the transverse glare of the blackboard on the sight of a teacher is avoided. In addition, the position of the lens 2 corresponding to the LED lamp 6 is provided with the groove 4, which has the function of light condensation, so that most light rays of the LED lamp 6 can finally pass through the lens 2, and the lens 2 is ensured to play a corresponding role in the light rays.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
