New description: [New technical field] This creation is about a kind of lamp, and especially related to a light emitting diode (LED) lamp. [Prior Art] Since the invention of the incandescent lamp by Thomas Edison, the world has widely used electric power for illumination. Heretofore, a high-brightness and durable lighting device such as a fluorescent lamp has been developed. Fluorescent lamps have the advantages of high efficiency and low operating temperature compared to incandescent bulbs. However, glory lamps contain heavy metals (mercury), which can cause environmental damage when discarded. With the development of lighting technology, a more energy-saving and environmentally friendly light source, namely a light-emitting diode lamp, has been developed. The light-emitting diode in the light-emitting diode lamp emits light by recombining electrons and holes in the P-N junction. Compared to incandescent lamps or fluorescent lamps, the illuminating one-pole luminaire has the advantages of low power consumption and long life. In addition, light-emitting diode lamps are more environmentally friendly without the use of mercury. In order to promote the light-emitting diode lamp as a light source for daily use, the appearance and light type of the light-emitting diode lamp should be designed to be the same as the current light bulb, so as to increase the public's willingness to use the light-emitting diode lamp. However, based on the heat dissipation considerations, the lower half of the existing light-emitting diode lamp is often provided with an opaque aluminum extrusion for heat dissipation, so that the lower half of the existing light-emitting diode lamp cannot emit light. In other words, the light type of the existing light-emitting diode lamp is the same as that of the current light bulb, so that the public's willingness to use the light-emitting diode lamp is not high. M438583 [New Content] With this in mind, this creation provides a light-emitting diode lamp with good bean performance. The present invention proposes a light-emitting diode lamp comprising a base, at least one light-emitting unit and a lamp cover. The base has a reflective surface. The light unit is coupled to the base and exposes the reflective surface. The light emitting unit includes a substrate and a plurality of flip-chip light emitting bodies. The flip chip type light emitting diode is disposed on the substrate. The lampshade surrounds the light • unit and reflective surface. x ^ In an embodiment of the present invention, the base includes a body and a metal shell that is sleeved on the body. The reflecting surface of the base is the surface of the metal shell. In an embodiment of the present invention, the material of the body is ceramic or plastic. In the embodiment of the present invention, the base includes a main body and a reflective film on the main body. The reflective surface of the pedestal is the surface of the reflective raft. In the embodiment of the present invention, the material of the reflective film described above is silver. In the embodiment, the above-mentioned light-emitting diode lamp is further provided with a column i-base and a light-emitting single (four) attached to the heat-dissipating column. The light-emitting unit transmits heat and dissipates heat. In the embodiment, the substrate of the above-mentioned light-emitting unit is dispersed. In the embodiment of the present invention, the material of the heat dissipating column described above includes gold in the creation of the real-cut towel, and the above-mentioned sublimation is inserted in the base 5 M438583 in the optical substrate of the present invention. In one embodiment, in the embodiment of the substrate of the light-emitting unit, the light-emitting unit further comprises a light-transmissive two-layer H (four) layer-shaped wire substrate on which the flip-chip is electrically connected.
