Abstract

A kind of remote phosphor excited white light LED down, comprise face frame, aluminium radiator, power drives, blue light LED light source assembly, power drives is located on aluminium radiator outer face, it is characterized in that, blue light LED light source assembly is assemblied in center in aluminium radiator by high-heat-conductivity glue, blue light LED light source assembly comprises PCB and is welded on the chip blue light LED light source in PCB, face frame is arranged on the openend of aluminium radiator, and yellow fluorescent powder bright dipping panel is fixed on the face frame end face in aluminium radiator inner chamber.Remote phosphor excited white light LED down of the present utility model, blue light LED light source sends after directly exciting yellow fluorescent powder bright dipping panel synthesize white light, blue-light LED chip does not directly contact with fluorescent material, avoid because the decay of fluorescent material and the reduction of launching efficiency cause the reduction of white light LEDs Down lamp luminous efficiency and luminous flux sustainment rate, the corresponding service life substantially increasing white light LEDs Down lamp.

Description

Remote phosphor excited white light LED down
Technical field
The utility model relates to a kind of remote phosphor excited white light LED down.
Technical background
Current white light LEDs Down lamp mainly comprises power drives (external), the aluminium radiator containing radiating fin of fixed lamp body structure, the white light LED light source component of center in aluminium radiator is assemblied in by high-heat-conductivity glue, be assemblied in the white frosted bright dipping panel on aluminium radiator, be assemblied in the face frame of aluminium radiator for fixing bright dipping panel, wherein white light LED light source component comprises PCB, employing SMT mode is welded on the chip type white light LED light source in PCB, chip type white light LED light source is by the phosphor gel synthesize white light of blue-light LED chip excite encapsulated around it.
The principle of luminosity of above-mentioned white light LEDs Down lamp is: the phosphor gel synthesize white light of blue-light LED chip excite encapsulated around it, and the white light that chip type white light LED sends directly sends from exiting surface equably through white frosted bright dipping panel.Because fluorescent material is directly encapsulated in around blue-light LED chip, during LED down work, the heat that blue-light LED chip produces can cause fluorescent material to produce heat fade, reduces the launching efficiency of fluorescent material, thus reduces luminous efficiency and the luminous flux sustainment rate of LED down.
Summary of the invention
The purpose of this utility model is just to provide that a kind of luminous flux sustainment rate is high, the remote phosphor excited white light LED down of perfect heat-dissipating, long service life.
Remote phosphor excited white light LED down of the present utility model, comprise face frame, aluminium radiator, power drives, blue light LED light source assembly, power drives is located on aluminium radiator outer face, it is characterized in that, blue light LED light source assembly is assemblied in center in aluminium radiator by high-heat-conductivity glue, blue light LED light source assembly comprises PCB and is welded on the chip blue light LED light source in PCB, face frame is arranged on the openend of aluminium radiator, and yellow fluorescent powder bright dipping panel is fixed on the face frame end face in aluminium radiator inner chamber.
Remote phosphor excited white light LED down of the present utility model, blue light LED light source sends after directly exciting yellow fluorescent powder bright dipping panel synthesize white light, blue-light LED chip does not directly contact with fluorescent material, avoid because the decay of fluorescent material and the reduction of launching efficiency cause the reduction of white light LEDs Down lamp luminous efficiency and luminous flux sustainment rate, the corresponding service life substantially increasing white light LEDs Down lamp.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
A kind of remote phosphor excited white light LED down, comprise face frame 1, aluminium radiator 2, power drives 4, blue light LED light source assembly 5, power drives 4 is located on aluminium radiator 2 outer face, it is characterized in that, blue light LED light source assembly 5 is assemblied in center in aluminium radiator 2 by high-heat-conductivity glue, blue light LED light source assembly 5 comprises PCB and adopts SMT mode to be welded on chip blue light LED light source 3 in PCB, face frame 1 is arranged on the openend of aluminium radiator 2, and yellow fluorescent powder bright dipping panel 6 is fixed on face frame 1 end face in aluminium radiator 2 inner chamber.
