Projection type lamps and lanterns light distribution analysis

Project category class class definition projection lamps and lanterns of lamps and lanterns is used for emphasis according to the body from the perspective of the light make using of the building decorative lighting, and is used to draw the outline of the outline of a large building, bar structure of the projection lamp radiator appears more good treatment. Can be divided into class IV, V, VI reflectoscope lamp, tube lamp, absorb dome light, ceiling lamp, project-light lamp, a lamp seem to V

classification class a narrow beam of light distribution

classification second canister light tube light as a tool of general lighting to use most of the time, in addition to the above mentioned to wash the wall, almost all our other V class light distribution.

canister light need efficient for general lighting. Panel control light cannot too pursuit of 'uniform surface 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.

category three dome light almost all of them are wide V class. Unable to effective shading, surface brightness of lamps and lanterns need to control. Panel light control become the main method.

category four ceiling lamp ceiling lamp general 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.

to achieve the whole lamp can be combined by light distribution class VI and VIII class light distribution, on the whole, class VI light distribution is very easy to meet the needs of field lighting, the combined light of ceiling light can be on the level of lamps and lanterns are combined with light, more flexibility.

category five interior space use project-light lamp wall lamp is mainly to solve the basic lighting. II, III, IV class the most commonly used.

II, III, IV class the most commonly used

3 d interior space 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.

small project-light lamp used for focus lighting, so the V class light distribution in the majority, though the narrow V class itself 'anti glare,' or to pay attention to light or shading design of lamps and lanterns of the structure.
