| 20100226022 | FRESNEL LENS, THE APPARATUS AND THE METHOD OF MANUFACTURING THEREOF - A Fresnel lens includes a plate made of a glass material and Fresnel portions made of plastic material and integrally formed onto the plate. A method of manufacturing the Fresnel lens includes the steps of adding the plastic material in a forming apparatus, curing the plastic material, and then separating the forming apparatus and the plate from each other to form the Fresnel lens. An apparatus for manufacturing the Fresnel lens includes a forming apparatus coupling with the plate of the Fresnel lens, and a forming concave with inversion corresponding to the shape of the forming Fresnel portions. The forming concave shapes the plastic material into the Fresnel portion. Therefore, the Fresnel lens takes lower manufacture cost than the glass Fresnel lens and has better reliability than the plastic Fresnel lens while exposing in high temperature and high light density. | 09-09-2010 |
| 20100033091 | LIGHT EMITTING UNIT AND METHOD OF MANUFACTURING THE LIGHT EMITTING UNIT - A method of manufacturing a light emitting unit includes steps of previously setting a threshold of luminous intensity, measuring luminous intensity of a measured light emitting unit, calculating an offset value between the threshold of luminous intensity and the measured luminous intensity, performing absorption of light by a light absorbing portion direct proportion to the offset value, and positioning the designed light absorbing portion onto an optical element of the measured light emitting unit. While light beam is radiated from the measured light emitting unit and passed through the light absorbing portion, few light energy is absorbed by the light absorbing portion to decrease the luminous intensity. Therefore, the light emitting unit with the light absorbing portion has a consistent luminous intensity due to the light absorbing ratio of the light absorbing portion is direct proportion to the offset luminous intensity. | 02-11-2010 |
| 20100033077 | LIGHT EMITTING DEVICE AND METHOD OF MANUFACTURING THE LIGHT EMITTING DEVICE - A method of manufacturing a light emitting device includes steps of setting a threshold of luminous intensity, measuring luminous intensity of a measured light emitting device, calculating an offset value between the threshold of luminous intensity and the measured luminous intensity, performing a destruct structure capable of decreasing energy of light beam on an optical element of the measured light emitting device, wherein the energy decreasing efficiency of the destruct structure is direct proportion to the offset value. While the light beam is radiated from a light emitting chip of the measured light emitting device and to the destruct structure, few light energy is absorbed or scattered by the destruct structure to decrease the luminous intensity. Therefore, the light emitting device with the destruct structure has a consistent luminous intensity due to the energy decreasing efficiency of the destruct structure is direct proportion to the offset luminous intensity. | 02-11-2010 |
