Intelligent all-round light type "LED high bay light 120W"

As we all know, the traditional incandescent lamp with high energy consumption, low efficiency. Based on energy conservation and environmental considerations, in North America, Europe, Japan and Taiwan are gradually plan to stop the sale of incandescent light. LED high bay light 120W, owing to its high brightness, low power consumption, long life and environmental protection, etc., become the preferred alternative to traditional incandescent lamps. However, LED is a directional light source, the need for an effective light distribution pattern to achieve the conversion of the small angle of the light into full light.
For the full range of lighting, the U.S. Energy Star made a strict definition, namely: 0o-135o vertical angle in the range of light intensity changes should be gradual, in this interval the light intensity at any angle required in this interval average intensity value of 80% -120%, and at least 5% of the total luminous flux to be in between 135o-180o.Specifically shown in Fig.

Hong Kong Applied Science and Technology Research Institute (hereinafter referred to as: ASTRI) LED lighting R & D team to successfully apply for the Hong Kong Government's Innovation and Technology Support Programme for a period of eleven months of full light bulb type of research and development. In response to this issue, research team first conducted for existing products and technical research. Currently, many large international companies such as Philips, Osram, Panasonic, etc. have launched a 40W to 60W incandescent alternatives. Table 1 gives the major manufacturers 60W replacement bulb findings. In general, you want to replace 60W incandescent, LED's power needs at least more than 10W.
On the technical side, you want to replace the traditional incandescent, generally use two methods, one is the use of optical components such as lenses, mirrors, and diffuser, etc. to adjust the light-emitting pattern, thus producing a full range of light. Another one is the LED chip through three-dimensional arrangement of the chip in all directions so that the light intensity distribution. Here are two ways a few typical design:

Using the multi-angle reflection inventors foliage and uniformly distributed on a flat substrate with an LED for, so that the reflected orthogonal projection of the page on the substrate to cover the plurality of LED high bay light 120W. Thus, part of the light emitted by the chip can be projected to the reflective surface of the leaf, and then be reflected to the surrounding space, and the other portion of the light can pass through the foliage of the gap, emitted from above.

Describes a blister wrap structure of the radiator. LED light-emitting components are placed on top of the radiator, and was a capable all-round light refraction as a light diffuser hooded. Based on reducing light loss considerations, the design of the outer section made of transparent glass bulb.

A composite lens is used to achieve the beam divergence. This compound lens can be divided into three parts, one part is in the top of the central lens LED high bay light 120W source can be part of the light emitted divergence. The second part of the wing-shaped lens, the light is partially reflected to the lower bulb periphery. The third part is the bottom of the lens may be the surface of the light reflective shine to the periphery of the upper bulb.

Wherein one substrate is placed horizontally, placed above a number of LED elements. Another piece of the substrate is an annular structure, and the first block placed on the substrate at an angle. The outer annular substrate placed in a number of LED elements measured.Thus, the first LED provided on one substrate of the light source direction, the second substrate to the edges of the LED as a light source. So as to achieve the purpose of full light.
