Field of the Invention The present invention relates to a light-emitting diode structure and an LED lamp thereof, in particular, a first colloid disposed between a groove of a substrate and a plurality of LED chips. a second colloid is disposed on the substrate and the first colloid is coupled with the first colloid, so as to effectively increase the overall light-emitting efficiency and heat-dissipating efficiency, the LED structure and the LED lamp with improved luminous and heat dissipation efficiency . [Prior Art] In recent years, the emerging lighting industry of Light-emitting diode (LED) has developed rapidly, making LEDs have exceeded or approached in terms of brightness, power, lifetime, power consumption, and reaction rate. The energy-saving light source of traditional light bulbs has led LEDs to gradually replace traditional light bulbs. Among them, high-power LEDs have been widely used in street lighting, landscape, wall washing, indoor lighting and other fields. ® and currently have a single high-power LED chip with a maximum power of 5 watts (W). In high-power applications such as street lights, there are usually hundreds of high-power LEDs or thousands of watts. W) LE and low-power packages are combined to form an LED module to achieve the required luminous flux and illumination, but the size of the corresponding LED module needs to be larger, and the required heat dissipation structure design is more To be complex, it directly limits its scope of application. In addition, since the thermal resistance of a single LED package can be less than U degrees Celsius per watt, the thermal resistance of the aforementioned modules after integration of multiple MDs is difficult to control, so that the LED chips in the LED module are in a long time. Under the work 201128110, 'the above-mentioned thermal resistance cannot be stably controlled, so that the junction temperature of the led wafer exceeds the allowable range and the performance and life of the LE1D wafer are damaged, such as the luminous efficiency of the LED wafer is lowered, and the emission wavelength is shortened. In addition, due to the scattered optical source, the external optical design for a specific application can be very difficult, so that it is difficult to obtain an ideal beam distribution. And 'because LED lamps use a plurality of LED chips to integrate the LED modules as light sources, they have received extensive attention and application, and their advantages are simple structure, less thermal interface, small luminous surface, concentrated and easy light distribution design. However, due to the high thermal power density of the LED module, it is difficult to solve the complex effects of the LED. Therefore, the LED lamp needs to consider the heat management of the LE:D module, and the LED module needs different light distribution in various applications.
