20140104853 | OPTICAL LENS FOR LIGHTING FIXTURE - An optical lens for lighting fixture includes a body, which comprises a bottom surface and a light-exit surface at opposing bottom and top sides thereof, an elongated groove formed in the bottom surface, a light incident surface, a first intersection line and a second intersection line respectively connected between the two ends of the elongated groove and the bottom surface, a first line segment and a second line segment respectively connected between the light incident surface and the bottom surface, a first virtual line defined between the two ends of the first line segment, a first distance that is the shortest distance between the two ends of the first intersection line, and a SAGi that is the shortest distance between any point at the first line segment and the first virtual line and satisfies the equation: 0≦|SAGi/first distance|×100≦2.8. | 04-17-2014 |
20140126218 | LENS MODULE FOR LED LIGHT SOURCES - A lens module for LED light sources including: a lens body; and an LED light source received in a recess of the lens body. By the conditions of Z1>Z2 and Z3>Y1, and with the shape of light incident surface and the position of LED light source, a light deflection effect is achieved. This allows light emitted from the LED light source to be refracted by the light incident surface and then emitted by the light exiting surface, generating an excellent light deflection effect, thereby increasing illumination in width at the road or public squares and increasing utilization rate of the LED light source. | 05-08-2014 |
20150300596 | Light Emitting Device and an Optical Element Used Therein - A light emitting device includes a lamp holder, a light emitting unit which is removably disposed on the lamp holder and includes a plurality of light emitting elements arranged in a closed configuration, and an optical element with a lens portion and a connecting portion and removably disposed on the lamp holder. The lens portion is formed in a closed configuration which is the same as the closed configuration formed by the light emitting elements, and the lens portion is aligned with the light emitting elements. The optical element can be removed via the connecting portion, then the light emitting unit is removed from another end of the elastic clamping unit, so that the light emitting unit can be easily replaced or removed. Besides, the light emitting unit can always fit in the same optical element no matter how the number of the light emitting element changes. | 10-22-2015 |
