摘要： An LED assembly according to an embodiment of the present invention may improve dark regions generated between LED chips by employing a first reflective layer between the LED chips. By employing a transparent optical layer or an optical layer including a scattering particle between an LED chip and a phosphor layer, direct contact between the LED chip and the phosphor layer may be avoided, thereby preventing a low light extraction efficiency. Further, by employing a second reflection layer on side surfaces of an LED chip, an optical layer, and a phosphor layer, a relatively high contrast may be obtained. An LED assembly may enhance contrast through a reflective layer while increasing light extraction efficiency by including a scattering particle in a phosphor layer.

摘要： A method of forming a fine pattern begins with providing a c-plane hexagonal semiconductor crystal. A mask having a predetermined pattern is formed on the semiconductor crystal. The semiconductor crystal is dry-etched by using the mask to form a first fine pattern on the semiconductor crystal. The semiconductor crystal including the first fine pattern is wet-etched to expand the first fine pattern in a horizontal direction to form a second fine pattern. The second fine pattern obtained in the wet-etching the semiconductor crystal has a bottom surface and a sidewall that have unique crystal planes, respectively. The present fine-pattern forming process can be advantageously applied to a semiconductor light emitting device, particularly, to a phonic crystal structure required to have fine patterns or a structure using a surface plasmon resonance principle.

摘要： An LED driving apparatus having a temperature compensation function includes a reference voltage generator for generating a first reference voltage and a non-inversion amplification unit for performing non-inversion amplification to a difference voltage between the first reference voltage and a forward voltage with a preset gain. A driving unit adjusts a supply voltage in response to the voltage from the non-inversion amplification unit to supply the adjusted supply voltage to a light source having light emitting diodes. A forward voltage detector detects the forward voltage at an anode of the light emitting diodes of the light source to supply the forward voltage to the non-inversion amplification unit. Luminance variation can be compensated according to temperature changes by using a forward voltage of an LED light source so that the forward voltage of the LED light source can be controlled in association with a target current value of ambient temperature.
