Description
Technical field
The utility model relates to field of LED illumination, specifically refers to a kind of LED area light source.
Background technology
LED area light source is by being encapsulated on one piece of heat-conducting substrate by multiple small-power integrated chip, thus the luminous intensity required by realizing.Current chip is electrically connected to two kinds of modes with circuit board, chip with chip: a kind of is connected for gold thread, and one is aluminum steel connection, and wherein gold thread link cost is higher, and aluminum steel link cost is lower.Gold thread reliably connects base material for gold or silver-colored, and the base material that aluminum steel reliably connects is gold.Pad on LED chip is golden material.
For improving luminous efficiency, silver-plated or application ceramic circuit board can improve the reflecting rate of chip on circuit boards, but this mode is because the pad on circuit board is silver-plated, LED chip is connected with the reliable electric connection gold thread of circuit board, and LED area light source is because being multiple chips integration packaging needs a lot of connecting lines, multiple chips effectively could be electrically connected, if all will be higher with gold thread link cost, and this condition of contact be used aluminum steel instead and can not reliably be connected.
Utility model content
It is high that the purpose of this utility model is to solve this LED area light source gold thread used price, and provide a kind of gold thread, aluminum steel to mix a kind of LED area light source of welding.
A kind of LED area light source, comprises circuit board, LED chip, aluminum steel, gold thread, glue, fluorescent material, it is characterized in that: circuit board is provided with can the circuit of conducting electrical signals, described circuit is provided with pad, does not have the place of circuit to be provided with LED chip on circuit boards, the rectangular array distribution of described LED chip, aluminum steel is welded with between LED chip and chip, be welded with gold thread between LED chip and circuit board, LED chip is provided with glue, fluorescent material, and LED chip inspires white light through fluorescent material.
As further improvement of the utility model, described circuit board is silver plating ceramic circuit board, silver coated aluminum base circuit board or silver-plated copper base circuit board.
The beneficial effects of the utility model are: by such scheme, and under the prerequisite ensureing product quality, not only reduce cost, also suit large area to popularize use.
