Three LED bollard lights have the exact same 15w LED array, the very same Samsung LEDs, the same driver, and utilize the very same amount of energy, but the amount and distribution of the emitted light differs. Why? The response: Optics.
The light produced by a bollard is always impacted by the location of the light source, the range of reflector, and the physical develop of the bollard housing. For example, while the three bollard lights utilize the exact same 15w LED range, one gives off 1,022 lumens while another tosses 2,089 lumens– more than twice as numerous. Let’s enter the function of each specific reflector and the net result of its optics. An excellent place How To Fix Led Christmas Light Strings begin is to view all the LED bollard lights with the same 15w LED selection, click on this link.
A Means of Comparison
We will present the 3 various bollard optics in the same way:
First is an image of false color making. It shows the quantity of light released, in color and with footcandle readings. The darker the color, the less light produced. In the event you loved this article and you would love to receive more info with regards to How To Use Led Light Strips kindly visit the web-site. Each number on the image represents the footcandles at a particular range far from the bollard. This provides a visual summary of light in a specified location. The location displayed in the false rendering images is 20′ x 20′.
Each reflector likewise has a graph that reveals the provided footcandles at various ranges from the bollard lights. While the charts are more accurate than the false color renderings, they do not provide as vivid a graphic.
You will likewise see light source lumens and provided lumens for each type of bollard light optic. Source of light lumens will be the same for each of the 3 bollards. Provided lumens represents the overall light produced by the bollard light with that optic. The last information point we will offer is the farthest distance from each bollard that is still lit with.5 footcandles, or 0.5 fc.
Louvered LED Bollard Light Optics
Louvered LED bollard lights are developed to direct the light down in an effort to lower glare and light trespass. Louvers substantially cut down emitted light along with the distance that light Where Can I Buy Led Light Shoes travel. Subsequently, louvers produce the least quantity of light and have limited light circulation.
Keeping a minimum of.5 footcandles between two of these louvered bollard lights would require spacing of 9 feet or less.
Type V LED Bollard Light Optics
Type V LED bollard lights are created to disperse the light out and all around the bollard. With the LED range mounted beneath the top of the system, the only limit to the light is the clear, prismatic, IES type V borosilicate glass refractor, which minimizes glare. While the refractor decreases glare and does not restrict the light, the amount of light released is somewhat decreased if compared to the specialized aluminum cone reflector. However, the distribution of light is more broad than that of a bollard with an aluminum cone reflector, so deciding between the two refers individual choice.
Aluminum Cone Reflector LED Bollard Light Optics
Aluminum cone reflector LED bollard lights are designed to direct the light down and out. The strength of the light is increased by the aluminum cone reflector. As with the other two 15w LED bollard lights, the LED variety on this bollard is mounted on the top. While the aluminum cone reflector increases the amount of light, it does not necessarily increase light circulation if compared with the type V optics, making the option in between aluminum cone reflector optics and type V optics a matter of individual preference.
