Description

LED light fixture with good heat radiating

Technical field

For docking national energy conservation project, in the LED use, research and develop at big caloric value.The present invention relates to a kind of lighting device, particularly relate to a kind of have great heat radiation effect be the imitative conventional incandescent lamp source of light source with LED, as LED: ball bubble, PAR lamp, smallpox etc.

Background technology

Lighting belongs to the daily life articles for use, and traditional lighting is the incandescent lamp that tungsten filament is made, and its ball bubble is shaped as popular institute to be liked, and still, the light efficiency of the incandescent lamp that tungsten filament is made is low, useful life short, thereby has restricted the use of incandescent lamp.

LED is light emitting diode, a kind ofly adopts electroluminescent semi-conducting material manufacturing to form, and LED has good characteristics such as voltage is low, usefulness is high, monochromaticjty is good, applicability is strong, good stability, the response time is short, the life-span is long, free from environmental pollution; LED adopts the low-tension supply power supply generally speaking, and supply voltage generally between 2-24V, has more security; The LED consumed energy reduces 80% with the incandescent lamp of light efficiency; Each unit LEDs is very little, can be prepared into the ligthing paraphernalia of different shape, and is suitable for different environment.

Have as above good characteristic just because of LED, so LED is widely used in the fields such as illumination, decoration, comprises the LED light fixture that adopts led chip to make.But, since the LED light fixture particularly miniaturization LED light fixture exist the junction temperature heat dissipation problem, therefore influenced promoting the use of of LED light fixture.

Summary of the invention

The objective of the invention is to overcome the deficiency of prior art, a kind of LED light fixture with the full-luminous angle of great heat radiation effect is provided, can solve the junction temperature heat dissipation problem of LED light fixture chip preferably, the good characteristic that had both kept the full-luminous angle of LED light fixture, can realize heat radiation again well, thereby effectively promote particularly promoting the use of of miniaturization LED light fixture of LED light fixture.

The technical solution adopted for the present invention to solve the technical problems is: a kind of LED light fixture with good heat radiating comprises that lampshade, radiating piece, led chip, installation led chip provide the power supply tube of power supply with lamp plate, for the LED lamp; Described lampshade is the hollow partial sphere structure that lower end and top are equipped with opening; Described lampshade, radiating piece, led chip, lamp plate and power supply tube connect in regular turn, described led chip is installed on the lamp plate, described lamp plate is arranged at the medium position place of radiating piece, described lampshade is wrapped in the top of radiating piece wherein, surround the cavity of a hollow by the outer wall on the top of lampshade and radiating piece, described lamp plate is arranged in this cavity; Described power supply tube is positioned at the below of radiating piece.

The invention has the advantages that simple in structure, good heat dissipation effect, be conducive to promote particularly promoting the use of of miniaturization LED light fixture of LED light fixture.
