Free containing space body LED and free containing space body LED lamp

Abstract

The invention belongs to the field of illumination, and particularly relates to a free containing space body LED and a free containing space body LED lamp, wherein the free containing space body LED and the free containing space body LED lamp can be applied in severe environments, can control luminous decay effectively, and can guarantee a service life. The free containing space body LED comprises a base, at least one light emitting unit and a lampshade, the base and the lampshade form a containing space, and the light emitting unit is arranged in the containing space. The shape of the containing space is formed through the connection of one side, facing the base, of the lampshade and the base, and the containing space is formed by a middle part and two parts on the two sides, the two parts on the two sides are hemispheric parts, and the hemispheric parts are connected with the middle part according to the shapes of the edges of the middle part. According to the free containing space body LED, due to the fact that the lampshade is a free-form surface, a special containing space is formed, a light field is adjusted effectively in the area, the illumination range is enlarged, an illumination area with higher intensity can be provided in the central area, and meanwhile the evenness of the illumination is taken into consideration.

Description

technical field [0001] The invention belongs to the field of LED lighting, and in particular relates to a free-accommodating space-body LED and a free-containing space-body LED lamp which can be used in harsh environments to effectively control light attenuation and ensure service life. Background technique [0002] Light-emitting diodes (LEDs) are semiconductor devices that generate a light field when excited in response to an electric current. With the continuous development of technology in this field, the lighting capability and system stability of LEDs have been continuously improved in recent years. At present, the research on the efficiency of light-emitting diodes is mainly focused on the use of high-transmittance materials for lampshades, such as high-transmittance outer covers and snap-fit ​​structures, to produce light-weight, non-oxidative, high-efficiency, energy-saving, and green LEDs. Light bulb. (the LED bulb with the publication number CN102588754A), but t...

Problems solved by technology

However, although the illumination range has been increased

In a certain area, the light intensity of this invention is weak. In addition, this invention is an improvement on the working front end of the light-emitting chip. The rational use of the light field of the light-emitting chip after generation is not involved, thus causing the loss of this part of the light field.

A light-emitting diode with publication number CN101937967B does not involve research on the problem of light-emitting chips producing squares. Therefore, how to provide an LED lamp that can effectively improve the light intensity, lighting range, and uniformity, and effectively save light loss is currently the Commonly Neglected Areas

At the same time, it should be pointed out that the angle of the light field illuminated by the current LED lamps is constant, which limits the lighting area of ​​the lamps, so the lamps can only cooperate at a fixed height, and the adaptability and adjustment ability of the environment are poor.
