Description

A kind of LED light fixture

Technical field:

The utility model relates to the illuminating product technical field, refers in particular to a kind of compact conformation, the fabulous LED light fixture of radiating effect.

Background technology:

As everyone knows, traditional incandescent lamp energy consumption is higher, and energy utilization rate is very low, is luminous energy less than 1/10th power conversion probably, other all is that form with heat energy has wasted, so people are trying every possible means and will come replace incandescent with new light source always.Therefore, electricity-saving lamp has just arisen at the historic moment, because Comparatively speaking it cheaply make well again, so obtained a large amount of application, the trend that progressively replaces incandescent lamp is arranged.Electricity-saving lamp is to adopt the electron luminescence excitation principle luminous, and with respect to incandescent lamp, electricity-saving lamp has the advantage of power saving, but the shortcoming that electricity-saving lamp exists is exactly: mercurous in the electricity-saving lamp, mercury plays the effect of intermediary in electricity-saving lamp, do not have mercury, and electricity-saving lamp just can not be luminous.So just cause electricity-saving lamp to have mercury pollution after production process and use are discarded, in addition, electricity-saving lamp still makes glassware, and is easily broken, bad transportation, bad installation.Secondly, its power consumption is still larger.At last, electricity-saving lamp damages easily, and service life is short.

And the developing direction of energy-saving illumination apparatus is exactly the LED light fixture at present.With respect to above-mentioned lighting, the LED light fixture has the following advantages:

1, energy-conservation.The energy consumption of white light LEDs only is 1/10 of incandescent lamp, 1/4 of electricity-saving lamp.

2, long service life.The life-span of LED lamp can reach more than 100,000 hours, was higher than incandescent lamp and electricity-saving lamp far away.

3, can frequent starting.If traditional electricity-saving lamp, incandescent lamp frequent starting or close, filament will be deceived and be easy to break down, and the LED lamp can not.

4, solid-state encapsulation, it belongs to the cold light source type, so its easily transportation and installation can be installed in any miniature equipment with sealing, is not afraid of vibrations.

5, environmental protection, LED does not have the harmful substance of mercury.The very easily dismounting of the assembling parts of LED lamp, it is convenient to reclaim.

Based on above-mentioned advantage, the LED light fixture will progressively replace other lighting.But, LED in the existing LED light fixture in the course of the work, 70% ~ 80% of input electric energy is transformed into can't be by the heat of radiation release, and the led chip size is little, if it is bad to dispel the heat, the led chip temperature is raise, cause that thermal stress distribution is uneven, and then cause chip light emitting Efficiency Decreasing and fluorescent material to swash problems such as penetrating decrease in efficiency, for the service life that ensures LED, the luminous efficiency that improves LED, generally all need LED is carried out good radiating treatment.

In the prior art, traditional LED light fixture all is equipped with for the radiator to the LED chip cooling, and the heat that this radiator produces the LED chip is in heat conducting mode, by circuit board, substrate, heat-conducting glue etc., conduct in the radiator dissipation of heat, because radiator can not directly dispel the heat to the LED chip, need certain medium auxiliary, thereby reduced the radiating effect of radiator.
