Abstract
The invention relates to a high-diffusion wide-angle LED lamp which comprises a ceramic substrate, electrodes arranged at the two ends of the ceramic substrate, an LED chip connected with the electrodes and a lens covering the LED chip. The lens is made of silicon in a compression molding mode and is fixedly connected with the ceramic substrate to form a whole. The upper surface of the lens is a semispherical curved face with a plane as the top. A concave portion is arranged in the upper surface of the lens and a side of the concave portion is a cone-shaped curved face. The bottom of the concave portion is a plane. According to the LED lamp, the lens and the substrate are formed at a time, an assembling axis and assembly height are accurate and the high-diffusion wide-angle LED lamp is formed to meet demands of all industries.
