Sentence examples for led lens from inspiring English sources

The optimal LED lens size parameter combination of the first stage was used in the second stage to create L25 56) orthogonal table, and then the Back-Propagation Neural Netwask (BPNN) was used to establish the LED lens quality predictor to predict the FWHM angle and luminance uniformity in different overall sizes.

· The plastic LED lens is safer than glass, which can break and cause harm to the user.

This study proposed a two-stage LED lens design optimization system, and used the viewing angle and the luminance uniformity as the optical quality objective.

An open ditch of approximately 2 mm in width and depth was made on the LED lens, and 4 cuts (2 × 2) were on the PDMS.

The CCA was laid in the ditch on the LED lens and then the CCA was fixed on the LED assembly by using suture to wrap them along the four cuts).

The lenses of these LEDs were embedded in epoxy resin that has the same refractive characteristics as the material encasing the LED thereby allowing the LED lens to be optically removed and direct view of the active element of the LED (creating a more uniform area of illumination across the LED heads).

Additionally, new developments in the field of lens design have led to lenses that show some degree of accommodation.

Moreover, in one case paracentesis led to lens injury requiring subsequent cataract surgery.

The natural ageing process of the lens leads to increased lens yellowing [ 24] and the aged lens contains UV-absorbers and chromophores that absorb both ultraviolet radiation [ 22, 25] and with age increasing proportions of violet, blue and to a lesser extent green light too [ 26].

It uses a 5W 455 nm light emitting diode (LED) and lenses to provide Koehler illumination at the proximal face of a 30,000-element coherent fiber bundle.

In this study, we investigate the accumulation of Aβ1 42 in the lenses of UPL rats, which then leads to lens opacification.
