Commercial lighting, how to use optical Angle consideration lamps and lanterns is good or bad? - China lighting network

Determine the pros and cons of a lamps and lanterns, in addition to the 'brand', how through optical Angle consideration of lamps and lanterns is good or bad, Suggestions from the following several aspects to observe, from the Angle of light beam can accurately meet the demand of application scenarios we can see from the perspective of the designer. Such as it is important to show a certain piece of clothing, need is the key light, so if the beam Angle is too large, only basic lighting, accent lighting, obviously will lack of visual appeal, reach the effect of focus, of course no problem at this moment with shoot the light, but also to pay attention to the beam Angle. For example, under normal circumstances, the Angle of 10 ° of stage light like the spotlight, concentrated and strong. 24 ° beam Angle is less than the focus, have a certain visual impact. And 38 ° Angle of light beam irradiation range is larger, more suitable for basic lighting. So, under the same power, the projection Angle and distance, if you want to focus on lighting, more inclined to use 24 ° beam Angle. Specific need how old beam Angle, of course, need according to the power of lamps and lanterns, the projection Angle, distance and according to the size of content and decide, so you want to assess whether or not the lamps and lanterns can accurately realize the Angle you want, it is one of the factors of purchasing lamps and lanterns of consideration. Second, from the Angle of the intensity of illumination, glare, deputy spot evaluation in commercial lighting, why some lighting system will make the customer feel uncomfortable? Or can't correctly show the characteristics of goods have? It is related to the intensity of illumination and glare. Businesses, ratio control based illumination and the intensity of illumination, can produce a variety of different effects. Which requires precise control technology of light, by far the most common method to control light is COB + + lens reflex. LED development initial period, the most commonly used control method is the use of scattered light light, this kind of method has the advantage of high efficiency, but worse, almost impossible to control the direction of the light, and it also produces glare. So this method, the strict sense, can really be realized the precise control of light. Later, the industry began to use big lens refraction method, advantage is start can control the beam Angle and direction, but exists the problem of low utilization ratio, and narrow beam design difficulty is high, moreover glare is still there. Then the advanced methods, the use of reflective cup to COB LED to control the light,

the way design is relatively mature, but the downside is still light utilization rate is low, and a new problem - — Deputy flare. In order to solve the above problems, the ideal way of COB LED point light lens and reflector was born. Both control the beam direction, and improve the efficiency, also reduced the glare, vice spot is the key to solve the problem. So from the optical design method of lamps and lanterns, at least with the method of lens and reflector, can achieve good effect of the light. The better solution is through the way of TIR + Fresnel lens, can make a beautiful light, the perfect use of light, the light efficiency is as high as 90%. Three, from optics material, temperature resistance, light transmittance and weather observations from single lens Angle, at present the mainstream market material is PMMA Acrylic) , good plasticity and high light transmittance ( 3 mm thickness of more than 93%) , it is especially suitable for such as commercial lighting places of this kind of light quality request is higher.
