Disclosed is a dock light assembly for illuminating a trailer interior. The dock light assembly may include a cylindrical housing having an illumination source therein, and an optical lens secured to an end of the housing. The optical lens may be configured to provide focused illumination to the trailer interior. A rotationally self-correcting screen device may be positioned between the illumination source and the optical lens. The screen device may be configured to absorb a portion of the focused illumination such that illumination to an upper portion of the trailer interior is reduced. The rotationally self-correcting screen device remains in a horizontal orientation even if the housing is rotated. One benefit of the disclosed dock light assembly is that forklift operators working in the trailer interior are shielded from high intensity light, even though the lower portion of the trailer interior remains brightly lit.

A modeling projection lamp has a stand, a driving assembly, a first pattern frame, and a second pattern frame. The stand has a first swing bracket and a first gear. The first gear is mounted on the first swing bracket. The driving assembly has a rotating mechanism and a second swing bracket. The rotating mechanism can drive the second swing bracket so that the first swing bracket is swung about a first axis and the second swing bracket is swung about a second axis at the same time. The second pattern frame is movably connected to the second swing bracket. With the second swing bracket swinging with respect to the first swing bracket, the second pattern frame can moves or rotates with respect to the first pattern frame. Therefore, the image formed via the first pattern and the second pattern can be a dynamic image.

Industrial lighting device including a light source and a sealed housing containing the light source. The housing includes a support delimiting a housing window extending opposite the light source, a window pane sealing the housing window, and a sealing gasket extending along the periphery of the housing window and compressed between the window pane and the support. The device includes a filter extending in front of the housing window, outside the housing. The filter includes a frame defining a frame window which is removably fixed to the housing, in an assembled position in which the frame window is opposite the housing window, and an optical film fixed to the frame and sealing the frame window. The device includes an elastic compression member arranged between the support and the frame.

Presented herein is an optical filter system for visible light, which has a first average transmittance T.sub.1 between a limit wavelength λ.sub.G and a wavelength of 700 nm and a second average transmittance T.sub.2 between a wavelength of 380 nm and the limit wavelength λ.sub.G. In this case: 410 nm<λ.sub.G<520 nm and 0.05

[00001]$<\frac{T_1}{T_2}<0.60.$

An illumination device (e.g., an electric candle, etc.) generally includes a shell, a housing coupled to the shell, a flame-shaped head disposed at least partially outside of the shell, and a pendulum supporting the flame-shaped head. The pendulum is pivotally coupled to the housing and configured to move the flame-shaped head relative to the housing. The illumination device also includes a first light source configured to illuminate the flame-shaped head, a second light source arranged inside the shell and configured to illuminate the shell, and a printed circuit board assembly operable to control the first light source to illuminate the flame-shaped head and the second light source to illuminate the shell.
