Light type centralized LED lamp

Technical Field

The utility model relates to the technical field of LED lamps, in particular to an LED lamp with a concentrated light type.

Background

An LED is a short-term light emitting diode, and uses a solid semiconductor chip as a light emitting material, which is made of a compound containing gallium, arsenic, phosphorus, nitrogen, and the like, and can radiate visible light when electrons and holes are combined. Compared with the traditional lamp, the LED lamp has the advantages of energy conservation, environmental protection, good color rendering property, good response speed and the like. White LEDs have therefore been widely used in various industrial or domestic settings. The LED lamp has the characteristics of high brightness, rich color types, low power consumption and long service life.

In the prior art, on one hand, light rays emitted by the light-emitting wafer to the periphery in the reflecting bowl cup of the bracket cannot be effectively utilized, and the luminance of a light spot is influenced; on the other hand, when the fluorescent powder of the LED lamp is glued with the glue on the surface, glue is easy to flow, so that the glue is not full enough in appearance, and the uniformity and the light-emitting angle of light spots are influenced. The existing mold top technology is used for manufacturing the rubber head, so that the product cost is greatly improved. Therefore, there is a need for a light type concentrated LED lamp to solve the above problems.
