Title:
LED ILLUMINATING MODULE
Document Type and Number:
WIPO Patent Application WO/2011/136522
Kind Code:
A2
Abstract:
The present invention relates to an LED illuminating module, and more particularly, to an LED illuminating module in which light emitted by LEDs has directionality by an asymmetric reflector having directionality to increase the propagation distance of the light, and in which the LED illuminating module has a cooling function and increases illumination thereof. The LED illuminating module of the present invention comprises an LED module in which a plurality of LED elements are arranged on a PCB having a connection circuit pattern for electrical connection of the LED elements; an asymmetric reflector, the horizontal cross-sectional surface of which has a right side with a reflecting angle of 20° to 40° and a near-vertical asymmetric left side, and the inner space of which becomes narrower as it goes from the top to the bottom, so as to collect light emitted by the LED elements such that the light has unidirectionality, wherein the asymmetric reflector has a vertical cross sectional surface with front and back sides with reflecting angles of 20° to 30°, and an inner space becoming narrower as it goes from the top to the bottom, wherein a coolant flow channel is formed between the front and back sides; a tubular fixed member having a singular body including a semi-circular lens portion and a space portion, wherein the lens portion collects the light reflected by the asymmetric reflector and enables the collected light to reach a long distance, and the space portion accommodates a substrate and the reflector; and soft rubber caps for sealing both ends of the fixed member.
