Description

Combined structure of light emitting unit

technical field

The utility model relates to a light source, in particular to a combined structure of a light-emitting unit that can increase the brightness of light-emitting devices by concentrating light sources and producing the effect of homogenizing multiple beams of light sources, and can effectively suppress multiple overlapping shadows.

Background technique

The most commonly used lighting units in daily life, such as: traditional tungsten white spherical bulbs, long strip fluorescent tubes containing mercury, spiral or multi-U tube type energy-saving bulbs, etc., because of their light per unit area The display energy is not large, and the phosphor powder containing mercury is coated on the outer cover glass tube, or an atomized light diffusion layer with a concave-convex surface is produced by sandblasting, so that the light can be irradiated evenly through the outer cover. When the person looks directly at the light source body due to carelessness, the feeling is soft but not dazzling and will cause dazzling phenomenon. Moreover, after the light-emitting surface of the light-emitting source is enlarged and homogenized, the light source is spherical, bar-shaped, and rod-shaped. U-shaped and other types of light emit light, and the light emitted evenly outward is not easy to cause obvious shadows on the illuminated object. If it is not deliberately observed, its existence is often ignored, so as not to disturb the user's attention. However, due to environmental protection and saving The consciousness concept of energy is paid more and more attention, the light-emitting elements mentioned above must be replaced and banned.

At present, the most environmentally friendly light-emitting element is none other than LED, but its unique point-emitting characteristics have brought great troubles to the convenience of its use. At this stage, the commercialization of so-called high-power LEDs is still immature and cannot be realized. For the high illuminance output of the light-emitting elements used in the past, it is necessary to combine multiple monomers into a lamp group, and use the addition of multiple units to obtain the total illuminance, so as to meet the minimum requirements of the lighting specification.

A lighting module composed of a plurality of lighting modules with similar luminous power, because of the similar position and similar brightness of each unit element, will produce the so-called "overlapping" phenomenon, which easily interferes with the user's visual effect and seriously causes distraction and visual fatigue.
