Description

Improved structure of LED lighting fixtures

technical field

The utility model relates to an improved structure of an LED lighting lamp, in particular to an LED lamp capable of forming multi-directional and large-scale lighting functions, and at the same time forming a structure with an excellent heat dissipation function when the LED is in operation.

Background technique

Light-emitting diodes are composed of semiconductor materials, which use the combination of electrons and holes in the semiconductor to emit photons to produce light-emitting components with different frequency spectra. According to the differences in packaging types, light-emitting diodes can be divided into bulb type (Lamp LED), dot matrix digital type (Display LED) and surface mount type (SMD LED).

The LED can only be energized in one direction, that is, forward bias. When the current flows, the electroluminescent effect of electrons and holes overlapping in it emits monochromatic light, and the wavelength and color of the light are related to the semiconductor used in it. The type of material is related to the elemental impurities infiltrated. LED lights have advantages that traditional light sources cannot achieve, such as power saving, high efficiency, long life, unbreakable, fast switching speed, and high reliability. In recent years, the development of light-emitting diodes has advanced by leaps and bounds. The brightness has been continuously improved, the colors have become more diverse, and the cost has been continuously reduced. However, light-emitting diodes have directivity when illuminated, which has become one of the shortcomings in use. Light has a certain directionality. If the light emitting diodes are arranged on the same plane, most of the light generated will be concentrated in the same direction, and a wide range of lighting effects cannot be obtained.

In addition, in addition to the visible light emitted by the LED, other energy is converted into heat and concentrated on the small chip, resulting in a hot spot with a relatively high temperature. The higher the temperature, the worse the luminous efficiency of the LED grain. This is the LED lamp. Another obvious shortcoming, so it is necessary to improve the luminous efficiency through heat dissipation, and at the same time avoid LED burnout.

Early LED lighting fixtures assembled a circular circuit board on the inner surface of a lamp holder containing a transparent lamp housing of a set size, and arranged multiple light-emitting diodes on the circuit board to provide illumination. However, since many LEDs are located on the same plane, On the circuit board, most of the generated light is concentrated in the same direction, so it is impossible to obtain a wide range of lighting effects.

In this regard, China Taiwan's new patent No. 100202259 "vertical tube LED light bulb" enables many LEDs to be installed on a vertical circuit board with various angles and directions, and then the circuit board containing the above structure is installed. Set in the glass tube, and insert multiple glass tubes containing internal LED circuit boards on the same lamp holder, through this method to enhance the lighting function of the LED lamp. However, this kind of LED light bulb structure seals most of the LEDs in the lamp tube, and the inherent heat dissipation structure is not ideal. China Taiwan New Patent No. 099208601 "Multidirectional LED Lighting Lighting" also installs many LEDs on a vertical internal circuit board at various angles and directions, and then seals most LEDs and circuit boards with a lampshade , also face the problem of heat dissipation structure.

Taiwan's new patent No. 099210936 "LED lighting with high-efficiency radiator" uses a cooling unit consisting of a large number of cooling fins and cooling holes on this type of LED lighting, as well as fan blades driven by a motor , the overall structure is complicated and the manufacturing cost is high, and it is also more energy-consuming and uneconomical.
