Abstract:
The present invention relates to a lighting device using an LED. One embodiment of the invention provides a lamp-shaped LED lighting device that can replace a known lighting device. The lamp-shaped LED lighting device promptly emits the heat generated by an LED element, which influences the optical output and the lifespan of the LED lighting device, through a lamp-shaped frame with a heat-ventilation structure that facilitates air circulation. In addition, the lamp-shaped LED lighting device prevents glare from an LED light source by using a lateral reflecting member, a diffusion lens and a diffusion cover and diffuses the light from the light source widely without optical attenuation. Another embodiment of the invention provides a tube and panel-shaped LED lighting devices that can be replaced with a previous tube-shaped fluorescent light and a panel-shaped lighting device. The tube and panel-shaped LED lighting devices rapidly emit the heat generated by an LED element, which influences the optical output and the life span of the LED lighting device, through a tube and panel-shaped frame with a heat-sink structure. In addition, the tube and panel-shaped LED lighting devices prevent glare from the LED light source by optically arranging a curved reflecting plate, a diffusion plate and a diffusion window which include a diffusion lens at the upper portion of the LED element. Furthermore, the tube and panel-shaped LED lighting devices diffuse the light from the LED light source widely without optical attenuation.
Abstract:
A prefabricated heating mat panel and an assembly thereof are disclosed, which comprises first and second electrode power lines, first and second terminals which are disposed at a corner of the heating mat panel or a center of the side of the same, a plurality of power line connection units, and a heating unit which is connected between the first and second electrode power lines and is heated. The whole connection structureis formed in a net-shaped connection structure along with first and second electrode power lines through a connection of the power line connection unit when assembling a heating mat panel.
Abstract:
Disclosed are a production method for a wholly aromatic liquid-crystal polyester resin, a wholly aromatic liquid-crystal polyester resin produced by means of the method, and a compound of the wholly aromatic liquid-crystal polyester resin. The disclosed production method for a wholly aromatic liquid-crystal polyester resin comprises the step of synthesizing a wholly aromatic liquid-crystal polyester resin by synthesising a wholly aromatic liquid-crystal polyester prepolymer by means of condensation polymerisation of a monomer and then reducing the pressure inside a reaction vessel containing the synthesised prepolymer at a predetermined rate of pressure reduction.
Abstract:
A apparatus for analyzing sample to prevent a sample from being stuck to a surface of the apparatus for analyzing sample in the course of being injected into the apparatus for analyzing sample. The apparatus for analyzing sample includes a platform having a disk shape. The platform includes chambers and channels, a sample inlet hole which is formed in an outer surface the platform and through which a sample is injected into the platform; an opening which is formed in the outer surface of the platform and through which a residual of the sample, present on the outer surface of the platform around the sample inlet hole, is introduced into a receiving space isolated from the chambers and channels; and a barrier which is formed on the outer surface of the platform around a portion of the opening to prevent the residual of the sample from moving past the opening in a radial outward direction of the platform.
