COB light source capable of uniformly emitting light

Abstract

The invention discloses a COB light source capable of uniformly emitting light. The COB light source comprises a base and a circuit board, a circuit board groove is formed in the base, the circuit board is installed in the circuit board groove, a plurality of COB light source blocks are installed on the circuit board, lenses are arranged on the surfaces of the COB light source blocks respectively, the surfaces of the lenses are installed on an installation sleeve, the mounting sleeves are connected through a first connecting block and a second connecting block, the first connecting block is arranged between the two transverse mounting sleeves, the second connecting block is arranged between the two longitudinal mounting sleeves, a mounting frame is arranged over the mounting sleeves, the size of the mounting frame is matched with that of the circuit board groove, and the mounting frame is of a rectangular structure. According to the COB light source capable of uniformly emitting light, the LED lamp is provided with the light uniformizing cover for wrapping the lens, the light source cannot be emitted from the side wall and the rear portion of the lens after penetrating into the lens, the light source can be completely gathered to the front portion of the lens to be emitted, the light emitting rate of the LED lamp is improved, and the light emitting uniformity and the brightness of the LED lamp are improved.

Description

technical field [0001] The invention relates to the technical field of COB light sources, in particular to a COB light source with uniform light output. Background technique [0002] LED (Light Emitting Diode), is a light-emitting semiconductor component, because of its good controllability, simple structure, small size, pure and rich colors, impact resistance, vibration resistance, fast response time, etc. One of the most promising high-tech products, while triggering the lighting revolution, it also makes a major contribution to promoting energy conservation, emission reduction, and environmental protection. [0003] The LED lamp is an electroluminescent semiconductor material chip, which is cured on the bracket with silver glue or white glue, and then connected to the chip and the circuit board with silver or gold wires, and sealed with epoxy resin around it to protect the inner core wire. Function, finally install the shell, so the anti-seismic performance of LED lights...

AI Technical Summary

Problems solved by technology

[0004]In modern lighting applications, light-emitting diode (LED) light sources are gradually replacing traditional light sources due to their energy-saving, high-efficiency, and good stability. It is a Lambertian distribution, and the light spot is circular when the light hits the plane, which cannot meet the application requirements of non-circular light spots such as rectangles.

[0005]The light output direction of the existing LED lighting fixtures is not uniform enough, which easily causes different lighting conditions in different areas, and cannot achieve uniform light emission. The backlight system often has a built-in light guide plate To guide the direction of light transmission, so that the light is evenly emitted from the light-emitting surface of the light guide plate

However, the luminous light of the existing light guide plate has the defect of insufficient uniformity.
