Detailed description of the invention
In the detailed description of the preferred embodiments of the present invention hereinafter, same or similar element is indicated by identical label, and their detailed description will be omitted.In addition,, for clear announcement feature of the present invention, the element in graphic is not described by actual ratio.
Fig. 1 is a schematic sectional view that shows the light emitting diode illuminating apparatus of the first embodiment of the present invention.
As shown in FIG. 1, this light emitting diode illuminating apparatus comprises an electric body 1, light source module 2 and a radiating module 3.
In the present embodiment, the end portion 10 of this electric body 1 is the nipple of a standard E27 type specification and its upper part 11 has a power module accommodation chamber 110.
This radiating module 3 has a horn-like hollow housing 30 that is placed in the top of the upper part 11 of this electric body 1.In the body wall of this hollow housing 30, be filled with cooling fluid 32.This hollow housing 30 has the minor diameter open end and the major diameter open end that the diameter away from this electric body 1 is larger than the diameter of this minor diameter open end that approach this electric body 1.
Should be noted that lens 4 can be used to seal the major diameter open end of this hollow housing 30.
This hollow housing 30 is provided with a radiating piece 31 at this minor diameter open end place.This radiating piece 31 has a radiating piece body 310 and multiple radiating fins 311 that radially extend to this housing 30 and contact with the intraparietal cooling fluid 32 of this housing from this radiating piece body 310.In the present embodiment, this hollow housing 30 is made up of glass and this radiating piece 31 is made up of the good material of the heat radiation as aluminium.On the other hand, cause unexpected generation, this coolant 32 can be loaded in a flexible container 33 of being made by the plastic material as PE, PTE in order to prevent cooling fluid 32 in this hollow housing 30 from flowing out when this hollow housing 30 cracking.
This light source module 2 comprises that one between two open ends of this housing 30, is placed in installation base plate 20 on this radiating piece 31, at least one is installed on light emitting diode 21 and on this installation base plate 20 and is placed in the power module 22 of the power module accommodation chamber 110 of this electric body 1 operationally.This light emitting diode 21 is electrically connected with this power module 22 via wire 23.Certainly, this light emitting diode 21 also can be electrically connected with this power module 22 via other mode.Because being electrically connected of power module 22 and light emitting diode 21 is well-known and be not the feature of this case, about the details of this part repeats no more.In addition, the mounting means of this light emitting diode 21 on this installation base plate 20 can be any suitable mounting means, as cover crystal type, wafer onboard (COB) mode, etc.
This light source module 2 also has a transparent protective shield 24, and this protective cover 24 is located on this installation base plate 20 can protect the light emitting diode 21 on this installation base plate 20.One phosphor powder layer 240 is coated in the one in the interior and outer surface of this protective cover 24.
