Quasi-fluorescence LED illumination monomer and application thereof

Abstract

The invention a quasi-fluorescence LED illumination monomer, which comprises a radiator, an LED substrate fixed on the radiator, and a plurality of LED illuminants encapsulated on the LED substrate. The first face of the radiator is provided with a paraboloid for reflecting light; a straight bar-type convex lens having radial converging effects is arranged in a space accommodated by the paraboloid; and the straight bar-type convex lens is positioned in front of the plurality of LED illuminants to radially converge but axially and diffusely emit partial light rays emitted by the plurality of LED illuminants. The illumination monomer radically solves the problems of spotted light source exposure, small illumination angles of optical paths, beaded light spots of the illuminant LED light source of lamps, visual dizziness caused by multiple projections formed by illuminating illuminated objects with a multiple-spot light source, dazzling light rays and the like existing in the conventional illumination lamps. The illumination monomer emits uniform and soft light rays, has high luminance in an illuminated area, has a light emitting mode which is basically not different from that of a conventional fluorescent lamp, and meets the requirements of people on use habit and approval for a long time. The invention also discloses various application of the quasi-fluorescence LED illumination monomer.

Description

technical field [0001] The invention relates to LED lighting / signal lamps, in particular to an LED lighting unit whose effect is similar to that of the existing fluorescent lamp fluorescent effect. The invention also relates to the application of the fluorescent LED lighting unit. Background technique [0002] Compared with traditional incandescent lamps, fluorescent lamps and other lighting fixtures, LED lighting has the characteristics of long life, high luminous efficiency, low power consumption and no phosphor pollution, and has a high degree of substitution. However, the existing LED lamp tubes available for lighting are all provided with circuit boards and LED arrays in the tube body of the lamp tube. On the tube wall, such LED fluorescent lamps have point light sources exposed, and the light path irradiation angle is small. The LED point light sources combined into fluorescent lamps are in the shape of beads, and the light is dazzling. The projection formed by the i...

Problems solved by technology

[0004] For example, in a typical scheme, two LED luminous bodies are arranged opposite to each other at both ends of the LED lamp tube, and double-sided reflective sheets or light-guiding materials or light-reflecting materials are arranged in the tube body. The light emitted by the LED luminous body passes through the double-sided Surface reflective sheets or light reflective materials are reflected or scattered by light guide materials, so as to be as close as possible to the light output mode of existing fluorescent lamps. Typical solutions of this type include LED fluorescent lamps disclosed in Chinese Invention Patent Publication No. CN101144591A, and Chinese Utility Model Patent Authorization Announcement No. CN200993322Y discloses LED fluorescent lamps, etc., but this type of LED fluorescent lamps is not very strong because of the small number of LED illuminants used, so it is difficult to adapt to daily lighting.

[0005] Another typical way is to mix a certain amount of astigmatism powder or light guide powder evenly into PC or PV lamp raw materials in the process of injection molding lamp tubes, and inject them into hollow lamp tubes. The light emitted by LED illuminants passes through PC or PV lamp tubes The PV light tube is transmitted. This kind of patent is like the LED fluorescent lamp with soft and multi-luminous angles disclosed in the Chinese utility model patent authorization announcement number CN201293218Y. not enough

[0006] Another typical method is to use an LED illuminant with an additional lens, such as a high-power LED fluorescent lamp disclosed by the Chinese utility model patent authorization announcement number CN201330956Y. However, this type of LED fluorescent lamp still fails to solve the above-mentioned related problems in LED fluorescent lamps.
