20130229825 | LIGHT SOURCE HAVING LIGHT EMITTING DIODE - An LED includes an LED chip, a first package configured for packaging the LED chip, the first package including a flat first surface, and a second package including a second surface opposing the first surface. A micro-structure is defined in the second surface and protruding toward the first surface. A gap is maintained between the first and second surfaces. The gap is filled with a filler, and the refractive index of the filler is smaller than that of the first and second packages. Light generated by the LED chip radiates first through the first package, then the gap and the micro-structure, thereafter the second package to finally reach an outside of the LED. A light module including the LED is also provided. | 09-05-2013 |
20140049725 | LIQUID CRYSTAL DISPLAY MODULE AND METHOD FOR MAKING SAME - A liquid crystal display module includes a light source and a liquid crystal module. The liquid crystal module includes a top glass substrate, a bottom glass substrate and a liquid crystal layer sandwiched between the top glass substrate and the bottom glass substrate. The bottom glass substrate covers the light source, and has a hollow inner space. A top wall of the inner space presents a number of microstructures extending down to the light source, for scattering light emitted from the light source before the emitted light enters the liquid crystal layer. | 02-20-2014 |
20140139357 | TRAFFIC LAMP WITH COLOR FILTER - A traffic lamp includes a white light source, three color adjusting units, a panel, a light absorbing unit and a light diffusion unit. Each color adjusting unit includes a reflector and a color filter. The three color adjusting units are rotatable relative to the light source such that a part of white light emitted from the light source is filtered to be blue and then reflected to project on the panel by one color adjusting unit, and another part of white light is filtered to be green and yellow and then reflected to project on the light absorbing unit by the other two color adjusting units. | 05-22-2014 |
20140140099 | LIGHT GUIDE PLATE HAVING UNIFORM LIGHT EMISSION AND MANUFACTURING METHOD THEREOF - A light guide plate includes a light incident surface, a side surface opposite to the light incident surface, and a light emitting surface connecting to the light incident surface and the side surface. The light emitting surface has a first portion adjacent to the light incident surface and a second portion adjacent to the side surface. The first portion defines a number of first micro recesses. The second portion defines a number of second micro recesses. In a plane perpendicular to the light emitting surface and the side surface, a cross section of each second micro recess is a portion of an ellipse. A major axis of the ellipse is inclined towards the light incident surface. A maximum depth of each second micro recess is greater than a maximum depth of each first micro recess. | 05-22-2014 |
20140177232 | LED MODULE AND METHOD FOR MANUFACTURING THE SAME - An LED module includes an LED unit having an LED chip, a lens covering the LED chip, and a diffusing film. The lens includes a light-incident face facing the LED chip, a light-emitting face opposite to the light-incident face, and a connecting face connecting the light-incident face to the light-emitting face. The diffusing film has a plurality of macromolecule diffusing particles mixed therein, and is coated on the light-emitting face of the lens. | 06-26-2014 |
20140211469 | DIFFUSING LENS AND PLANAR LIGHT SOURCE HAVING DIFFUSING LENS TO INCREASE LIGHT UNIFORMITY - A diffusing lens includes a first surface and a second surface facing away from the first surface. The first surface has a first negative Fresnel structure for diffusing light from a point light source. The second surface has a second negative Fresnel structure aligning with the first negative Fresnel structure and for further diffusing the light of the point light source. | 07-31-2014 |
20140339208 | LASER MACHINING DEVICE AND ADJUSTING METHOD FOR SAME - A laser machining device includes a laser emitting device, a supporting device including a supporting surface, a controller, and optical detecting units mounted on the supporting surface. The laser machining device sets an X-Y coordinates having an original point and moves to being substantially above one of the optical detecting units. | 11-20-2014 |
20150036347 | COMPOUND LENS AND LED LIGHT SOURCE DEVICE INCORPORATING THE SAME - A compound lens includes a first lens and a second lens coupled to the first lens. The first lens has a light incident face and a light exit face opposite to the light incident face thereof. The first lens defines a recess at a center of the light exit face thereof. The second lens has a refractive index lower than that of the first lens. The second lens is received in the recess of the first lens and a light incident face of the second lens directly contacts the light exit face of the first lens. A light emitting diode light source device incorporating the compound lens is also provided. | 02-05-2015 |
20150036356 | OPTICAL LENS AND LIGHT SOURCE MODULE HAVING THE SAME - A light source module includes a light source and an optical lens facing the light source. The optical lens includes a light incident surface facing the light source, and a light emitting face opposite to the light incident face. The light emitted from the light source is entered into the optical lens from the light incident face, and exited from the light emitting face. A refractive index of the optical lens gradually decreases along a direction from the light incident face to the light emitting face of the optical lens. | 02-05-2015 |
20150043217 | LIGHT EMITTING DIODE LIGHT SOURCE MODULE HAVING UNIFORM ILLUMINATION - An LED (light emitting diode) light source module includes a first optical lens, an LED light source received in a groove of the first optical lens and a second optical lens located at a light path of the LED light source and above the first optical lens. The first optical lens includes a first reflecting surface around the groove and a second reflecting surface. The second optical lens includes a reflecting surface facing the LED light source, and light which is incident to the reflecting surface of the second optical lens is reflected thereby to the first reflecting surface and the second reflecting surface of the first optical lens. A light diffusion plate is attached to the second optical lens at a position away from the reflecting surface of the second optical lens. | 02-12-2015 |
