PAR light lens type, specification and Application (PAR30,PAR38)
PAR light lens
Preface: This article refers only to the lens for PAR light with high power LED (1W, 3W, 5W single etc.)
PAR lights classification
Series: PAR22, PAR30, PAR38, PAR64 etc
二,PAR lights lens specifications (size )
1.The series lens using quantitative differences, such as the PAR22 uses 3 lens, PAR30 uses 5 or 7 lenses; whether it is PAR30, PAR38, the LED lens design specifications are the same, the maximum diameter is about 19.8mm, bayonet ( step ) is about 17.8mm in diameter;
2.PAR lightslens height are generally of two (it focuses on cup internal structure) is linked to 10.5mm or 12mm
PAR lightslens installed also has two ways in addition to the use of lights Cup front panel with fixed bayonet.
3.1. The lens against LED, inner diameter the of lens is 6.0mm to 7.0mm, lens height is10.5mm
3.2 Lens Trap LED, inner diameter of lens is 8mm (with a lumileds or imitation lumileds specifications ); there is also a small inner diameter of 6.8mm ( for CREE LED );
4. Lens can be flat surface, concave surface, clear surface, frosting surface, ledns surface;
三.PAR lights lens angle and facula requirements:
1 PAR lights lens angle range is wide: it can choose 15, 25, 38, 45, 60 degrees and other specifications,
2 PAR lights lens use 38 degrees at present;
3 PAR lights lens require center facula average, when a plurality of lens focusing on, the facula can overlap (light shape is a round, brightness increasing);
4 because of the different style can choose different surface treatment processes ,such as clear surface, frosted surface or the ledns surface ,it must get different facula effects ( round facula, diffuse facula etc. );
Reference Information
1. PAR lights power supply using 110V or 220V;
2. PAR lights power interface using E27 or GU10;
3. PAR lights lens is not affected by the above two constraints, it is only parts (an optical device to be concentrating effects;)
4. PAR lights lens is not limited to use with spotlights, it can also be used in other LED lighting.
