Abstract

The invention relates to a light emitting diode surface light source device, which comprises a substrate and a plurality of light emitting diode chips arranged on the substrate in array type arrangement. The thickness of the substrate is between 1 and 3 mm. The area of the light emitting diode chip is between 0.08 and 0.25 mm<2>; and the distance between every two light emitting diode chips is more than twice of the dimension of the chip. The light emitting diode surface light source device uses the chip with small dimension and controls the distance between the chips and the thickness of the substrate, can achieve the promotion of luminous efficiency of the whole surface light source device through utilization of the chip with the small dimension, can maintain the temperature of the chip in a lower state, reduce the amplitude needed for radiation and is further favorable for the following radiation design of the whole light emitting diode surface light source device.

Description

technical field [0001] The invention relates to a light emitting diode device, in particular to a light emitting diode surface light source device in which a plurality of light emitting diodes are arranged to form a surface light source. Background technique [0002] see figure 1 Shown is the three-dimensional schematic view of the Taiwan Publication No. 289947 of the prior art. In the case of Taiwan Publication No. 289947, what is disclosed is a technology that a plurality of light-emitting diode chips 91 (hereinafter referred to as chips) are arranged on a substrate 92 to form a side light source, and the size of the chip 91 is below 40mil (especially in the 8mil~14mil), so as to increase the light extraction efficiency and improve the thermal conductivity. [0003] But in fact, in addition to the size of the wafer 91, the distance between the wafers 91 and the thickness of the substrate 92 itself will also affect the heat dissipation of the entire surface light source, ...
