Description

Hanging type natural light blackboard lamp

Technical Field

The utility model relates to an illumination lamps and lanterns, it is the lamp that classroom blackboard illumination of a section was used, and it is a suspension type nature light blackboard lamp, and it distinguishes on structure and light with common blackboard light, and its light parameter is close the light parameter of sunlight when 8 ~ 9 o' clock in the nature, and at this moment light is very suitable for reading and writing, does not hinder the eye and does not sting the eye. The international commission on illumination (CIE) specifies standard light sources for natural light as: the color temperature is about 4000K and the color rendering index is 100. The suspended natural light blackboard lamp utilizes the LED lamp beads to emit light, light rays are not directly emitted through the configuration of various internal light guide materials, the light rays are reflected to a light intensifying film made of special materials through a reflecting plate, the light rays emitted outwards through the light intensifying film are close to natural light, the light rays are emitted in a diffuse reflection mode, the light ray color temperature of the blackboard lamp is measured by a light measuring instrument to be about 4000K, the color rendering index is more than 98, and the light rays are very comfortable. It adopts the suspension type structure, fixes on the roof, and the mounting height exceeds the blackboard, does not block that the student watches mr and writes on the blackboard, does not also influence mr's teaching, so can satisfy the needs of teaching development.

Background

Along with the development and the use of the LED lamp beads, most of the existing lamps adopt the LED lamp beads to emit light, so that the LED lamp beads are energy-saving and high in luminous efficiency. If the standard of natural light is to be achieved, the light must be emitted by diffuse reflection. At present, a plurality of blackboard lamps are directly arranged on the upper frame of the blackboard, and some blackboard lamps also adopt a hanging type, the luminous sources of the blackboard lamps basically cannot emit natural light, and the light is dazzling. Some reflectors for blackboard lamps have unreasonable structures, so that the illumination on the blackboard is uneven. The natural light blackboard lamp adopts the light emitted by a special process to be reflected to a layer of brightness enhancement film through a light diffuse reflection plate, and the light index emitted by the brightness enhancement film reaches the standard of natural light. In order to achieve the uniformity of the light illumination on the blackboard, the lamp is horizontally placed, the light irradiates the ground linearly, the side light irradiates the blackboard, and the intensity of the light directly irradiating the blackboard is reduced. And the light is reflected to the blackboard by utilizing the reflective surface of the bucket type lampshade on the lamp to supplement the light, so that the illuminance of the lower half part of the blackboard is enhanced, and the problem of light nonuniformity of the whole blackboard is solved.

Disclosure of Invention

This patent provides a suspension type natural light blackboard lamp, and it will have lamp shade (1), LED lamp pearl (2), reflector panel (3), light guide plate (4), membrane (5) that adds lustre to, first gallows (6), power adapter (7), second gallows (8), shell (9) to constitute. The whole lamp is a flat lamp, and a bucket-type lampshade is added on one side surface. The lamp chooses LED lamp pearl (2) for use as the light source, and it arranges around dull and stereotyped lamp, and light enters into light guide plate (4) from edge all around and gives out light, and the reflector panel (3) of its back of recycling comes with light diffuse reflection, has one deck membrane of adding lustre to (5) in the outside of light guide plate (4), plays the effect of adding lustre to. Be shell (9) around the lamp, make with the aluminum product, help lamp pearl dispels the heat, on whole lamp was connected to a power adapter (7) with the wire, the power cord was connected to the other end of power adapter (7), and power adapter (7) are fixed on the lamp plate back with the screw. The outmost of the lamp is provided with a bucket type lampshade (1), and the whole lamp is hung in the air by a first hanging frame (6) and a second hanging frame (8) in the horizontal direction.

The beneficial effects of this patent are that diffuse reflection is luminous, and light is even, simple to operate.

Detailed Description

The patent of the utility model provides a suspension type natural light blackboard lamp, it will have lamp shade (1), LED lamp pearl (2), reflector panel (3), light guide plate (4), membrane (5) that adds lustre to, first gallows (6), power adapter (7), second gallows (8), shell (9) to constitute. The whole lamp is a flat lamp, and a bucket-type lampshade is added on one side surface. The lamp chooses LED lamp pearl (2) for use as the light source, and it arranges around dull and stereotyped lamp, and light enters into light guide plate (4) from edge all around and gives out light, and the reflector panel (3) of its back of recycling comes with light diffuse reflection, has one deck membrane of adding lustre to (5) in the outside of light guide plate (4), plays the effect of adding lustre to. Be shell (9) around the lamp, make with the aluminum product, help lamp pearl dispels the heat, on whole lamp was connected to a power adapter (7) with the wire, the power cord was connected to the other end of power adapter (7), and power adapter (7) are fixed on the lamp plate back with the screw. The outmost of the lamp is provided with a bucket type lampshade (1), and the whole lamp is hung in the air by a first hanging frame (6) and a second hanging frame (8) in the horizontal direction. The lamp is 200mm higher than the upper edge of the blackboard, and the distance between the lamp and the blackboard is 750 mm. The light at the lower half part of the blackboard is reflected to the blackboard surface by the reflecting surface in the bucket type lampshade (1) to play a role of light supplement. The cover shell of the bucket type lampshade (1) can block light, so that the student can be prevented from directly seeing the shining light.
