High-uniformity LED line light source

Abstract

The invention discloses a high-uniformity LED line light source. The high-uniformity LED line light source comprises an LED line light source body, and the LED line light source body comprises an outer shell; partitions are arranged in the outer shell; the outer surfaces of the partitions are fixedly connected with the inner wall of the outer shell; light source chambers are formed between the partitions and the outer shell; and light source circuit boards are arranged in the light source chambers. According to the high-uniformity LED line light source, the partitions divide different LED light source illumination groups, and the illumination ranges of the LED light source illumination groups are controlled to be the same; the refractive index of the light source is improved through a reflective inner layer inside, a first reflector and a second reflector, illumination brightness of the LED light source illumination groups is improved, and illumination brightness is the same; and unidirectional reflective glass has good reflective index, brightness of the light source is improved through unidirectional reflective glass, the advantage that illumination uniformity is high is achieved, and the problems that illumination brightness of a conventional LED linear lamp is different, light is bright on one side and is dark on the other side, and illumination of the line light source isaffected are effectively solved.

Description

technical field [0001] The invention relates to the technical field of LEDs, in particular to a high-uniformity LED line light source. Background technique [0002] The LED light source is a light source in which light-emitting diodes are illuminants. Light-emitting diodes are referred to as LEDs for short. Visible light can be radiated when electrons and holes recombine, so they can be used to make light-emitting diodes. It is used as an indicator light in circuits and instruments, or as a text or number display. Gallium arsenide diodes emit red light, gallium phosphide diodes emit green light, silicon carbide diodes emit yellow light, and gallium nitride diodes emit blue light. Due to chemical properties, it is divided into organic light-emitting diode OLED and inorganic light-emitting diode LED. [0003] When the existing LED linear lamps are in use, because the LED linear lamps emit linear light sources, and because the illumination brightness of the existing LED lin...
