Problems solved by technology

However, whether it is an LED lamp designed with a reflective cup or a lens, the light collection efficiency of the LED lamp bead is still low, and the light spot irradiated by the reflective cup is uneven, and the center light intensity of the light spot irradiated by the lens is not high. The LED lights of these two schemes will both produce dazzling effects on the human eye; when multiple LEDs are used for mixed light at the same time, the separate reflector cup and lens will produce uneven light mixing and different colors peeling off

Abstract

A LED lamp and a light effect improving method thereof. A bulb shell (2) is covered on LED beads (3), and is mounted in a reflection cup (1). The bulb shell (2) is used for processing a primary optical process for the light emitted by the LED beads (3). The reflection cup (1) is used for processing a secondary optical process for the light which is subjected to the primary optical process performed by the bulb shell (2). By the functions such as refraction, scattering, diffusion and the like of the bulb shell (2), the primary emergent light emitted from the LED beads (3) is subject to the primary optical process such as mixing, scattering and so on, so as to realize the treatment effect that the light is emitted from the three-dimensional surface of the bulb shell (2). The reflection cup (1) performs the secondary optical process, so as to reflect the scattering light within a certain angle range.

Description

【Technical field】 [0001] The invention relates to the field of semiconductor lighting, and more specifically relates to an LED lamp. 【Background technique】 [0002] At present, LED light sources and LED lamps widely use reflective cups made of plastic (adding electroplating process) or aluminum materials, or lenses made of transparent PC and PMMA materials for secondary optical treatment, which have better light treatment effects. It can be used in a wide range of fields. However, whether it is an LED lamp designed with a reflective cup or a lens, the light collection efficiency of the LED lamp bead is still low, and the light spot irradiated by the reflective cup is uneven, and the center light intensity of the light spot irradiated by the lens is not high. The LED lights of these two schemes will both produce dazzling effects on the human eye; when multiple LEDs are mixed with light at the same time, a single reflector cup and lens will produce uneven light mixing and dif...
