Product : Portable High Definition optic lens for broadcast shootings
Light sources at lighting emitting area : multiple arrayed LED chips at the space 138.5 x 70mm
Developed lens: Diffuser Sphere Fresnel Lens
The product DIYPRO was requested to develop is portable flat panel lighting for broadcast shooting.It is not a newly developed product using the light source at light emitting area of existing product. What DIYPRO was requested development was to improve optic lens area.Before the request of development given to DIYPRO, the light surce of light emitting area of the existing product used 138.5 x 70mm LED Panel(Super high CRI Power LED) and controlled the light distribution by dffuser.
There was following problem when the light distribution is controlled using the existing diffuser( existing optic lens)
1. Decline of illuminance
2.Change of color temperature
3. Change of color coordinate
◈ Measurement of illuminance and light distribution without any optics
Illuminance : 672lux
Color temperature : 6141K
◈ Measurement of illuminance and spectra applying the existing diffuser
Illuminance : 505lux
Color temperature : 5715K
2. FWHM : Ø635mm –> Ø555mm(12.5% reduced)
3. Color temperature and color coordinates: changed–> no change
