10W to 300W Bridgelux Citizen Cree Osram COB LED Fresnel Lens High Borosilicate 3.3 for Stage Light High Bay Light

Fresnel lens is used for LED light source to increase light efficiency and brightness. Compared with the same lens and LED light, the focal length and distance are different, and the angle of outgoing light can be set arbitrarily. Single light or multiple array LEDs The lights can be designed according to the needs. The size of the lens can be designed according to customer needs, and the light output angle can be adjusted to reduce the cost of mold opening. Precise machine tool processing realizes the accurate transmission of light. Features: Fresnel lens has the advantages of ultra-thin structure, super large size, ultra-light weight, arbitrary shape cutting, excellent light transmittance, low price, light and easy to carry, etc. It has more advantages than traditional convex lenses, and its weight is less than Convex lens, suitable for many occasions. Widely used in: LED floodlights, colorful floodlights, lighting, landscape lights, signal lights, wall washers and other lamps.

Product Application

Bridgelux Citizen COB LED Optical glass (high borosilicate, K9, BK7, BK270) Optical Lenses For High bay light,Spotlight,Street light. It has extremely low thermal expansion coefficient, extremely high temperature resistance, excellent chemical stability, excellent electrical insulation, low and stable ultrasonic delay performance, best ultraviolet spectrum transmission performance, and visible light and near infrared spectrum transmission performance. , and has higher mechanical properties than ordinary glass. Optical glass has excellent spectral characteristics. It transmits both infrared and ultraviolet light. It can be applied to high bay lights, street lights, spotlights, industrial and mining lights.

The Hongxuan(Shenzhen Hongxuan Optoelectronic Technology Co.,Ltd) lens offers low-profile lenses specifically designed for the Luxeon LEDs, OSRAM LEDs ,Bridgelux LEDs or Seoul LEDs,Cree LEDs. A software-optimized aspheric profile enables the generation of several different beam output patterns:narrow,medium,elliptical and wides beams. The high collection efficiency reaches 85% of the total flux emitted by the LEDs. Lens holders are available in white or black,and provide the proper alignment the between the LEDs and the lenses,set correct distance between the lens and LED. The lens holder can be glued to the PCB to provide a secure assembly.

The LED lenses are for CREE,Lumileds,Osram,Seoul,Nichia,Bridgelux,Citizen,Prolight LEDs.and can provide street light lens,flood light lens,lighting lens,MR16 lens,Par22 lens,Par30 lens,Par38 lens,stage lighting lens,flashlight lens,hybrid light lens. These TIR optics are used to get narrow beams with smaller LED's or allow you to use the larger source LED’s and even multi chip LED's. As with the other TIR ranges, we have a number of beams to allow you to use the same size optics for a number of beam angles.
