20110085329 | LENS MODULE AND LED ILLUMINATION DEVICE USING THE SAME - This invention relates to a lens module and a LED illumination device using the same. The lens module includes a plurality of lens units and a plate. Each of the lens units includes a lens body, a first engaging structure and a second engaging structure. The lens body has a light incident surface at a top thereof and a light exit surface at a bottom thereof. The first and second engaging structures are arranged at peripheral edges of the lens body. On the other hand, the plate defines a plurality of seats for accommodating the lens units. Each of the seats includes an aperture from top to bottom of the plate to receive the respective lens body of the lens unit, a supporting structure arranged at peripheral edge of the aperture of the seat to engage with the respective first engaging structure of the lens in order to prevent the lens unit from falling off the seat, and a suppressing structure arranged at peripheral edge of the aperture of the seat to engage with the second engaging structure of the lens in order to prevent the lens unit from upward withdrawal of the seat. | 04-14-2011 |
20110194279 | LED LIGHTING DEVICE WITH LED LAMPS PROTECTED FROM FALLING OFF - A LED lighting device includes a LED module and a diaphanous cover. The LED module includes a circuit board and a plurality of LED lamps. Each of the LED lamps includes a lens unit and a LED package. The lens unit includes a lens body, a frame and at least one pillar. The frame extends from a periphery of the lens body and is mounted on bottom of the circuit board. The pillar extends downward from a bottom surface of the frame. The LED package is mounted in the frame, and has a light emitting surface facing the lens body and a back surface joined to the bottom of the circuit board. The diaphanous cover abuts upward against all distal ends of the pillars of the LED lamps and is secured on the circuit board of the LED module. | 08-11-2011 |
20120081700 | OPTICAL MEASUREMENT SYSTEM - An optical measurement system includes a holder, a bracket, a plurality of optical sensors, a motor and a processing unit. The holder is provided for holding a test light source at the origin of a spherical coordinate system. The optical sensors are located on the bracket at different elevation angles with respect to the origin. Moreover, the optical sensors are spaced the same radial distance apart from the origin to aim at the test light source. The motor is configured to drive either the holder or the bracket to rotate such that the test light source at the origin is able to relatively rotate with respect to the optical sensors about a zenith axis of the spherical coordinate system. The processing unit is coupled to the optical sensors for processing of data captured from the optical sensors. | 04-05-2012 |
20120113651 | LAMP CUP AND LIGHTING APPARATUS COMPRISING THE SAME - A lamp cup, adapted to be coupled with a luminous module, includes a cup body and a lens. The cup body includes a top wall and an annular sidewall extending downwardly from a periphery of the top wall. The top wall has a top surface to be joined with a circuit board of the luminous module and defines an aperture from top to bottom therein at a position corresponding to a light emitting component of the luminous module. The lens is securely mounted in the aperture of the top wall of the cup body to be aligned with the light emitting component. | 05-10-2012 |
20120194820 | GONIOPHOTOMETR FOR MEASURING 3D LIGHT INTENSITY DISTRIBUTION OF LIGHT SOURCE - A goniophotometer includes an arc reflector; a holder for positioning a light source at the center of the arc reflector; a stationary detector substantially disposed at the center of the arc reflector and aimed at an arc reflective surface of the reflector; a driving device for rotating the holder with respect to the reflector and the detector about an axis of the light source; and a computing unit configured to convert a detection result of the detector into a measurement value. | 08-02-2012 |
20120195034 | LIGHT GUIDE ASSEMBLY AND LIGHT FIXTURE USING THE SAME - A light fixture includes a portable light source and a light guide assembly. The light guide assembly includes a reflective mask and a lamp holder. The lamp holder is mounted on the reflective mask for removably positioning the portable light source on the reflective mask. The reflective mask is configured to reflect light emanated from the light source in a predetermined pattern when the portable light source is held in place by the lamp holder. | 08-02-2012 |
20120240976 | LIGHT ASSEMBLY - The present invention discloses a light assembly, which includes a transparent main body and a lens. The transparent main body includes an interior chamber gradually expanding from bottom to top, an inner wall encircling the interior chamber, and an outer wall encircling the inner wall. The outer wall is a total internal reflection surface. The inner wall includes a plurality of first facets facing a first direction and a plurality of second facets facing a second direction which is different from the first direction. The first facets and the second facets are provided to encircle the interior chamber respectively. Either side of each of the first facets is connected to one of the second facets, and each of the two adjacent first facet and second facet form an angle therebetween. The lens is fitted into the main body and faces the interior chamber of the main body. | 09-27-2012 |
20130215619 | NON-IMAGING OPTICAL LENS AND LIGHTING DEVICE HAVING THE SAME - The present invention relates to a non-imaging optical lens and a light-emitting module having the same. The lens includes a concave region having a continuous curved optical surface formed by a plurality of facets spliced together. The continuous curved optical surface faces the light-emitting device. The curved surface consists of an array in at least three rows of the facets and at least three columns of the facets | 08-22-2013 |
