An LED lamp according to the present invention emits light approximately in all directions like a small filament lamp. The LED lamp is a light emitting bulb-shaped unit, and comprises an epoxy resin bulb-shaped portion; two leads of which one end is extended outside the bulb-shaped portion and the other end is embedded in the bulb-shaped portion; and an LED chip connected to the ends of the two leads and embedded in the bulb-shaped portion. The surface of the bulb-shaped portion of the LED lamp is formed in an appropriate process to be a frosted glass surface, a cut-diamond surface, a surface covered with small particles, or an optically-diffusing cap. Thus, a durable, non-fragile, and small power-consuming LED lamp can be obtained.

Une lampe à diode électroluminescente (LED) qui, selon la présente invention, diffuse la lumière dans presque tous les sens, à la manière d'une petite lampe incandescente. La lampe LED est un dispositif de diffusion de lumière qui présente la forme d'une ampoule, comprenant une partie en résine d'époxy, à la forme bulbeuse; deux fils dont une extrémité s'étend à l'extérieur de la partie ampoule et dont l'autre s'enchâsse à l'intérieur de ladite partie bulbeuse; et une puce LED branchée sur l'extrémité de chacun des deux fils et implantée dans ladite partie bulbeuse. La surface de la partie bulbeuse de la lampe électroluminescente est créée selon un processus approprié en vue de produire une surface de verre givré, de diamant coupé, aux petites particules, ou en forme de chape à diffusion optique. L'invention propose donc une lampe à diode électroluminescente qui est résistante et peu énergivore.
