Description
Technical field
This utility model belongs to light emitting diode construction encapsulation field, is specifically related to a kind of COB light
Module.
Background technology
Owing to the encapsulating structure of light emitting diode is open structure, itself does not have sealing
Can, be easily subject to again simultaneously the water in outdoor environment, dust or pollution gas impact thus
Reduce the service life of light emitting diode.General, outdoor lighting lamp is in shell junction
Add seal gasket or be coated with the methods such as fluid sealant, the light emitting diode module within protection.Such
Means of defence, limits three dimensional designs and the design creativity of lamp outer casing.Make outside outdoor lamp
Shell is stiff, does not design sense.Meanwhile, because junction scribbles fluid sealant, maintenance is changed internal
Light source or power supply exist inconvenient or change and easily make the barrier propterty of shell decline.
Compression molding techniques refers to: plastics or rubber size in closed mould cavity by heating, add
Press and be shaped to plastic processing (being also the rubber processing) method of goods.Be usually by powdery,
Granular, pellet shape, lamellar, be the most first made and the material base of goods similar shape, be placed on heating
Mould die cavity in, then mold closing pressurization so that it is molding also solidifies or vulcanizes, then obtains through the demoulding
Goods (see figure), this method is particularly well-suited to the molding of thermosetting plastics (see thermosetting resin) and adds
Work.
Vacuum coating technology: a kind of technology being produced thin-film material by physical method.At vacuum chamber
The atom of interior material isolates from heating source the surface getting to plated object.Technique is
First it is used for producing optical glass, such as long glass eyeglass etc..After extend to other function films,
Disc is aluminized, decoration film coating and material surface modifying etc..As Watchcase plates simulating golden colour, machinery
Cutter plated film, changes processing red hardness.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of protection
Higher ranked COB light module.
For solving the problems referred to above, the technical scheme that this utility model is used is as follows:
A kind of COB light module, including circuit substrate, luminescent device, module shell, power device
Part and waterproof wiring female seat, described luminescent device, power supply apparatus and waterproof wiring female seat are arranged on
On circuit substrate, described luminescent device is electrically connected with waterproof wiring female seat by power supply apparatus,
Described module shell is by moulding shaping process compression moulding transparent outer cover on circuit substrate, institute
State module shell and include that cavity body and plastic entity, described cavity body are positioned in plastic entity
Portion, described luminescent device is positioned at cavity body, and described power supply apparatus is positioned at plastic entity, institute
State waterproof wiring female seat and be positioned at the edge of plastic entity.
Preferably, there is a groove at the middle part of described module shell, under the longitudinal section of described groove is
Narrow wide trapezoidal, and described groove is positioned at the surface of luminescent device.
Preferably, also including highly reflecting films, described highly reflecting films sputter is recessed at described module shell
On the side of groove.
Preferably, the thickness of described highly reflecting films is 0.1mm.
Preferably, described luminescent device is light emitting diode, and described light emitting diode outer wrapping
There is the silica gel being mixed with fluorescent material.
Compared to existing technology, the beneficial effects of the utility model are:
The structure design that this utility model is open for luminescent device and power supply apparatus determines, adopts
With sealing luminescent device and the structure of power supply apparatus so that the degree of protection of COB light module is more
High.Use the module design of optoelectronic integration so that module profile is compacter.Near sending out
The side shell of optical diode uses vacuum coating technology, the opaque height that sputter one layer is white
Reflecting material, it is ensured that light penetrates along a less angle, prevents light to surrounding divergence loss.
When utilizing this COB light module to manufacture LED lamp, there is due to itself the effects such as water proof and dust proof,
Being no longer required for lamp outer casing is that rule is smooth so that have bigger designing LED outward appearance when
Degree of freedom, LED lamp profile is had the space of more imagination design.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model COB light module.
Reference: 1, module shell；2, luminescent device；3, circuit substrate；4, power supply
Device；5, waterproof wiring female seat；6, highly reflecting films.
