LED lighting and emitting light

Emitting light source, belongs to the directional LED directional light LED is far from the requirements of indoor lighting.

1, nature and lighting

in our earth, regardless of the lower and higher; No matter simple, intelligent; Regardless of living organisms, such as plants and animals, they are feeding, growth in the sun. Sunshine in space light way affects the living forms on earth, also affect the person's physiological and psychological state. So in this sense, glowing sunshine to life on earth from space.

2, LED lighting, the status quo of

light human knowledge, the standard index of artificial light, all begins with natural light. From the first generation of artificial light, tungsten filament bulbs, to the second generation of double U energy-saving lamps, they glow of way and the way the sun shine luminescence for the space. As the fourth generation of lighting of LED light source, to meet the needs of the indoor lighting, we must know the characteristics of the indoor space geometry, the characteristics of the indoor space geometry is low height, the level of the area is large, therefore, demands for artificial light source the light uniform, soft, dark corner, give a person a kind of psychological bright lighting effects. Directional light emitting leds for indoor lighting, because of its light Angle, it not only can't meet the needs of the indoor lighting, but also will affect the person's physiological and psychological state.

one of, is according to area will appear obvious difference between light and shade.

within the scope of the light Angle, focus on the LED the main light, according to the objects in this area is particularly strong brightness; While outside the scope of light Angle, showed an obvious dark space. Two areas of light and shade flux difference > 50%. Glare caused by strong contrast, which is one of the reasons, also can make people physiological and psychological feeling unwell.

second, directional light LED is not uniform.

the LED light Angle of optical axis direction of luminous flux value and 50% luminous flux ( Luminous intensity? ) The Angle between the half power Angle for the LED. This definition determines the leds in the Angle of light itself is not uniform.

existing technology using frosted cover change of light transmission path, is to some extent, can increase the light Angle, but it still belongs to the directional light emitting light way. With frosted cover solve the problem of uniformity of the directional light emitting LED light source, due to the directional light emitting Angle element LED inner glow inhomogeneity, LED to the luminous intensity is high, the frosted cover optical axis direction and the other the phenomenon of weak light, can we learn from Japanese consumers in June 2012 hall issued the first ban in the LED light source, can be confirmed, consumer hall said: 'there is a problem of the product, all bearing glowing' total luminous flux values, e. 13 ~ 69% lower than the standard. 。 。 。 。 。 。 ”。 In addition, the use of frosted cover solution light loss, also need to cause our enough attention.

as a result, the existing technical solution of frosted cover is not an ideal solution, thoroughly solve the problem, we must think the LED components through 360 degrees of space.

3, 360 - degree LED LED 360 degrees, the half power light Angle of 360 degrees, glowing light shining or QuanGuangShu shine for the space. The glowing effect can be according to space make full of the light beam.

with 360 degrees of component manufacturing LED light source used in indoor lighting, it has the advantages of: the first is the LED light-emitting components implemented 360 degrees space, need not use frosted cover can be directly use transparent blister as chimney, so can reduce the loss of light, made of 360 degrees to the LED light source, no lighting a corner, not dazzling, no glare, brightness distribution is appropriate, shadow and less ghosting, stereo sense is strong shape; It and people are accustomed to using tungsten filament lamp, energy-saving lamp can realize seamless docking.

4, 360 degrees about simulation of LED light source component

we should clarify light-emitting LED light source components and real-time simulation 360 degrees space distinction between 360 degrees space light LED. On single components implemented on a 360 - degree space light LED, because its in the spatial arbitrary Angle, known as real-time space for 360 degrees. So-called simulate light-emitting LED light source component is 360 degrees space will many of the directional light distribution of LED in the plume, simulated space glow into 360 degrees, therefore, simulation of 360 degrees of LED light source the light components still belongs to the directional light source.

as a result, 360 degrees is LED indoor lighting the best lighting solution.
