On many occasions we can see this as symmetrical lighting fixtures, lamps, and other direct-type call, but I believe that many people do not understand the meaning of this title, the
Here Prius lighting for you to do a detailed explanation about the classification and definition of symmetry lamps light type
(asymmetric light distribution type) lamps: a symmetric (asymmetric) light intensity distribution of the lamp. Relative to the symmetry plane defined by an axis or.
Direct luminaires: Can emit 90% to 100% of the luminous flux of the lamp directly to the lower part of the fixture.
Semi-direct type lamps: 60% -90% can transmit directly to the lower part of the luminous flux of the lamp fixture.
Diffuse lighting: can emit 40% to 60% of the luminous flux of the lamp to the lower part of the fixture.
Semi-indirect lighting: can emit 10% to 40% of the luminous flux of the lamp directly to the lower part of the fixture.
Indirect lighting: direct flux can emit 10% less than the lower part of the lighting fixtures. Widely according to type lamps: make a relatively large pool in the three-dimensional angular distribution of the lamps.
According to type of lighting: the light in the middle three-dimensional angular distribution of the lamp. Deep according to type lighting: the light in a small three-dimensional angular distribution of lamps.
Ordinary lamps: No special requirements of dust or moisture, such as lamps.
Protection type lamps: specialized protective casing structure to prevent dust, water, gas and water from entering inside the lamp shade. Degree of protection code usually consists of the letters IP and two characteristic features of digital.
Dust lamps: You can not completely prevent dust from entering, but without prejudice to enter the amount of equipment normally used lamps.
Dust-tight luminaires: no dust into lamps.
Waterproof lighting: preventing water from entering the structure function of the lamp. Such as drip, splash, anti-water, anti-rain and so on.
Watertight lighting: under certain conditions to prevent water from entering the luminaire. Underwater Lighting: Lighting can be used in long-term water under pressure. Proof lighting: for explosion hazard areas, in line with the rules of the explosion-proof enclosure using lamps.
Flameproof lighting: lamps can withstand an internal explosion of an explosive gas mixture pressure, and can prevent internal explosion of an explosive mixture around to cover the spread lamps lamps.
Increased safety lamps:
industry lighting parts
Under normal operating conditions, can not produce a spark could ignite an explosive mixture or the temperature of the lamp structure, measures to improve safety, to avoid abnormal conditions or under normal conditions approved by the above phenomenon lamps.
Debug lighting: use the appropriate means to make the main components can rotate or move the lamp fixtures.
Movable fixtures: After power is on, can be easily called from one place to another fixture. Suspended lamps: with sling, sling chain, hanging tubes suspended ceiling or wall lamps on bracket.
Lift Suspension lamps: the use of pulleys, counterweights, etc. can be adjusted pendant lamps hanging high. Recessed Lighting: Security lighting installation or partially embedded within the surface. Ceiling with: surface mounted directly on the ceiling lamp. Downlight: usually concealed in the ceiling so that the light beam focused on a small corner of the lamps. Wall: fixed directly on a wall or pillar of lamps.
Floor lamp: mounted on high pillars and stand luminaries on the ground. Lamps: on a table or other portable power source connected to the lamp.
Portable lights: with a handle and connect the power cords for portable lamps. Spotlights: the use of reflectors and refractors high intensity lamps in a limited solid angle. Searchlight: typically have a diameter greater than 0.2m in the mouth and produce approximately parallel light beam of high intensity floodlight.
Floodlights: beam divergence (beam width) greater than 10 °, Spotlights, usually turning and pointing in any direction.

Spotlight, Spotlight: typically have a diameter of less than 0.2m and the formation of the optical port is generally not more than 0.34rad (20 °) concentrated beam divergence angle floodlight.
Emergency lights: emergency lighting lamps in general.
Evacuation lights: have emergency evacuation signs lighting the lamp, including the exit sign lights or point lights.
Exit sign lights: mounted directly above or near the exit sign indicating the location of lights.
Point marker lamps: packed in evacuation channel refers to the direction of the exit sign lights.
Road lighting: used in conventional road lighting lamps. Cut their light into light type, half light and non-light-based cross-sectional
Left light type lighting: the direction of maximum light intensity 0 ° ~ 65 °, the maximum allowable intensity values of 10cd / 1000lm and 30cd / 1000lm lamp its angle of the 90 ° and 80 ° directions.
Half-light type lighting: the direction of maximum light intensity 0 ° ~ 75 °, the maximum allowable intensity values of 50cd / 100lm and 100cd / 1000lm lamp its angle of the 90 ° and 80 ° directions.
Non-Cut - Off Lighting: On a 90 ° angle which direction the light intensity of the lamp maximum allowable value 1000cd
