Abstract

The utility model discloses a shadowless illumination device based on hexagon LED array is by LED lamp strip, lamp stand, lamp shade, hinge, lighting fixture, form from lock -switch, fastening seat. LED lamp strip is equilateral hexagon through the lamp stand and arranges the lower surface at the lamp shade, and the lamp shade that three chip architectures are the same passes through the hinge and links to each other with the lighting fixture, and contained angle each other is 120, lie in the center of lighting fixture from the lock -switch, whole lamps and lanterns link to each other with wall or cantilever through the fastening seat. Equilateral hexagon is arranged into to LED lamp strip can be with the light source of the synthetic large tracts of land of line source, just so can from three different angles lightmap to the workstation, both guaranteed that there is sufficient luminance in the field of vision, the shade of head, hand production has also been weakened to the while. This invention has characteristics such as rational in infrastructure, no shadow is respond well, the use flexibility is convenient, the temperature rise is little, provides a realistic plan for promoting the LED shadowless illumination technique.

Description

A kind of non-shadow illuminating apparatus based on hexagon LED array

Technical field

This utility model belongs to LED indoor lighting field, and in particular to a kind of shadowless lighting based on hexagon LED array Device.

Background technology

Being furnished with special lighting source workbench used in scientific research and field of engineering technology, with electric filament lamp and fluorescent lamp more Based on.This light source has that color rendering index is poor, the low defect of brightness, easily makes one to produce the dimmed illusion of feeling of fatigue and illumination. The problem that concurrently there are shade causes inconvenience for engineering drawing and when checking large scale drawing.

LED illumination compares traditional lighting, and brightness is higher, and working life is longer, while low-carbon energy-saving, it has also become whole world illumination Technology develops irreversible trend.Wherein, the LED of high-power and high-luminance can reduce the umbra of light source itself, but its maximum light Beam angle is only 120 °；Light-source brightness can be caused using the cumulative of constant current operation mode, resistance and LED lamp bead parameter error more than LED Concordance is reduced, therefore the optical design that it is critical only that light fixture of LED shadowless lightings research.

A kind of non-shadow illuminating apparatus based on hexagon LED array have high brightness and suitable illumination depth, can play Illuminance is uniform, light quality preferable shadowless lighting effect, and its is rational in infrastructure, easy to use and flexible, can be widely applied to scientific research and Field of engineering technology.

Utility model content

For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of nothing based on hexagon LED array Shadow illuminator, devises the three lamp faces for being mutually 120 ° being made up of hexagon LED array, using the face light on three directions To eliminate the umbra of illuminated object and the handss shadow of people, and the function of timing shutdown can be realized, with it is rational in infrastructure, without shadow effect Well, it is flexible and convenient to use, the features such as temperature rise is little.

This utility model is achieved through the following technical solutions：A kind of non-shadow illuminating apparatus based on hexagon LED array, its It is characterised by：By LED lamp bar (1), lamp socket (2), lampshade (3), hinge (4), lamp bracket (5), self-lock switch (6), fastening seat (7) group Into；LED lamp bar (1) is arranged in the lower surface of lampshade (3), three chip architecture identical lampshades by lamp socket (2) in equilateral hexagon (3) it is connected with lamp bracket (5) by hinge (4), angle each other is 120 °, and self-lock switch (6) is in lamp bracket (5) The heart, whole light fixture is connected by fastening seat (7) with wall or cantilever.

The length of described LED lamp bar (1) be 10cm～20cm, the linear battle array comprising 10～15 high-brightness LED lamp beads Row, in 4500Kelvin～5000Kelvin, the reflecting rate of lampshade (3) is more than 95% for colour temperature.

Described lamp bracket (5) is contained within timing circuit, and continuously work reaches 10 hours then automatic spring self-lock switchs to light fixture (6) and cut off the electricity supply.

Operation principle of the present utility model is：Due to the straightline propagation principle of light, shade, shade are formed during light irradiation object The part of middle complete darkness is referred to as umbra, and the slightly shallow part of surrounding is referred to as penumbra, and the main purpose of shadowless lamp design is to the greatest extent Possibly weaken interference of the umbra to the people visual field.The light-emitting area of light source is bigger, and the umbra of object is less, and penumbra occurs therewith More level, therefore, this utility model designs the LED lamp bar (1) for constituting high-brightness LED lamp bead in lampshade (3) lower surface Arrange according to equilateral hexagon, line source is synthesized a large-area light source by lamp socket (2) for powering, three lampshades (3) it Between be mutually 120 °.So, just light can be irradiated on workbench from three different directions, have both ensured that the visual field has enough bright Degree, while also reducing the shade that head, hand are produced.Three identical lampshades (3) are by hinge (4) and lamp bracket (5) It is connected, irradiating angle and light intensity can be adjusted, for the facility that user provides maximum.Additionally, for the consideration of practical application, Continuously work automatically cuts off power supply to this utility model after 10 hours, and prolonging service lives of lamps also can energy saving.

The beneficial effects of the utility model are：(1) LED have that color rendering index is preferable, brightness is high, long service life etc. it is excellent Point, this utility model can play on the table preferable local shadowless lighting effect, and color distortion can be preferably minimized into journey Degree, for a long time using being difficult to feel fatigue；(2) this utility model reduces heat effect, temperature rise using cold light source and Open architecture It is little, it is not necessary to heat filter；(3) the mounting means simple operation that LED lamp bar (1) is arranged in equilateral hexagon, eliminates irregular The expense that shape PCB is drawn a design.
