Canister light, shoot the light, cast light lamps and lanterns with what kind of light distribution is the best? - Lighting network

the projection type lamps and lanterns is used for emphasis according to the body, from the perspective of the light class IV, V, VI light distribution are common. Specific differences, advantages and disadvantages, and then look down, please. First of all, we look over this a few simple class with light light way: (before and after the class IV light distribution: R0 - R180) Strong asymmetry, or so ( R90 - R270) Symmetry. Type V class with light: light round, lantern shape, beam Angle can be narrow width. Class VI light distribution: wide beam Angle, square, and V class is a little similar, left and right sides is symmetrical, asymmetry, before and after light in all directions. Accent lighting project-light lamp of small project-light lamp are mostly used for focus lighting, mostly in the V class light distribution on the market. Although narrow V class itself 'anti glare,' or to pay attention to light or shading design of lamps and lanterns of the structure. The shoots the lamp as one of the most common focus of the accent lighting lighting lamps and lanterns, most of them adopt V type of narrow beam of light distribution, the light effect is similar to 'torch'. However, we say, but the most widely used, is is the best? Question 1 v class with extremely narrow light distribution lens central has a blind spot, and too much reflection cup shape affect the appearance. If you want a soft light effect, use frosted hood will sacrifice certain intensity. Bring as shown, high-power lamp generally more than the light source is used, if use the left and two kinds of light distribution in the middle ( V class) , pay attention to the red box shot, the light contact ratio is low, the result is prone to ghosting on is according to the content. And most the right side of the IV class with high contact ratio, light is focused on the long, is not easy to appear the aforementioned problems. 2 if the question according to body shape not sure, may be better than V class IV class light distribution. As shown in figure, this is a work of art, usually there will be a wide variety, the interpretation of art to above way of polishing is to focus on the human body on the back, but the author meant to express the key is how to? Many times we don't know. For works of art lighting, we emphasize try not to destroy itself. At this point, the use of V type of light distribution to be thoughtless according to the shape of body, too much emphasis on a certain part and lost the whole picture of the artistic conception, use focus on the long class IV with light evenly illuminated the whole picture, their effect is as follows: bring IV class ( Right) Compared with the V class ( Left) Focusing of light distribution, long, can be more widely light images. Question 3 marginal sharp out light and soft. Illumination lighting design problem, of course, the position and Angle is very important, but it's also important to sharp and soft light itself: lamps and lanterns is marginal sharp and soft depends on light distribution, the results of the same beam Angle differs very far, visible light type is very important. Bring about two shoots the light beam Angle, and is a light under uniaxial, but from the point of the effect of software simulation, flare have obvious difference. See light distribution curve, which can be found that 50% light intensity is not the same as the extension of the axis, a narrow, a relatively wide. General lighting of the canister light tube light is used as a general lighting tool most of the time, are almost V class light distribution. Used for general lighting tube lamp need to be efficient, panel control light cannot too pursuit of 'uniform' effect. For the inner surface of tube light reflection is the influencing factors of light distribution. Especially in the narrow V type of light distribution, requires precise control of light, and the internal reflection easy to break with the accuracy of the light. Therefore, canister light mostly USES the wide light distribution, matches all kinds of light distribution may be used. Absorb dome light of general lighting use wide V class with light, almost all unable to effective shading, surface brightness of lamps and lanterns need to control, so the panel control become the main means of light. The general lighting ceiling lamp ceiling lamp is multi-purpose V, VI class light distribution. According to the need can also have I, II class light distribution, but III and IV class is relatively rare. Class VI with light, the light shows square, light in all directions, it is easy to meet the needs of field lighting, to achieve the ideal result. While the V class has very strong vertical light, very low double. To achieve the whole lamp can be combined by light distribution class VI and VIII class light distribution. General lighting of interior space use project-light lamp wall lamp is mainly to solve the basic lighting. Many project-light lamp light distribution types, including class II, III, IV, the most commonly used. Take a look at this a few kinds of light distribution effect: above simulation is a convention and exhibition center use different types of light distribution effect, you can see, the class IV effect is very good, Again, the class IV out light left and right sides is symmetrical, strong asymmetric) before and after Downwards, lamps and lanterns, normal vision will not produce glare, but it can light up the whole space is relatively uniform. Of course, some situations such as art gallery have to do a spot, such as V analog figure. But, in fact, in order to put the space in the middle area lights, do not cause too much contrast, still carry the lamp a little bit of elevation, may have the effects of glare in reality. To see the top view of class IV: so, from the perspective of the exhibition hall effect simulation diagram of above, class IV comprehensive performance is the most outstanding. Interior space is three dimensional proportion change multiterminal, cosmetic requirements of lamps and lanterns is unified, light distribution is varied. In order to satisfy the large spatial distance ratio, class IV is the best.
