Abstract
The utility model discloses an even illumination type LED lamp bead, including diode wafers (1), a lens (2), a gold thread, a pin (4), packaging glue, a radiation pole (5) and a pedestal (6). The diode wafers (1) are positioned at the top of the radiation pole, and is connected with the pin (4) through the gold thread; the lens (2), the pin (4) and the radiation pole (5) are assembled as a whole through the pedestal (6); and packaging glue is filled in the cavity enclosed by the lens and the pedestal. The even illumination type LED lamp bead is characterized in that the lens (2) employs a flat structure, the surface of the lens is provided with several rings of prisms (3), each ring of prism possesses a light extraction surface outward to the center of the ring, the diode wafers (1) are arranged on the top surface of the radiation pole in an annular shape, the lens (2) completely covers all diode wafers (1), and the LED lamp bead is advantageous by even light extraction.
Description
Technical field
The utility model relates to LED lamp pearl field, relates in particular to a kind of polycrystalline sheet encapsulated LED lamp pearl.
Background technology
Development and expansion along with the LED application product; Encapsulating structure to the LED wafer has also proposed more requirement because the unique characteristics of luminescence of LED, such as LED photochromic single, rising angle is little, caloric value is big, unidirectional conducting or the like; All need in concrete illumination scheme, adapt to; Relate to from the chip architecture to the wafer package, each aspect from the light source design to the fitting structure, the encapsulating structure of existing LED lamp pearl includes parts such as diode wafer, lens, gold thread, pin, packaging plastic, heat sink, pedestal; The monolithic diode wafer is fixed on heat sink flat top surface; And with convex lens capping in addition, this LED lamp pearl power is less and bright dipping is inhomogeneous, is difficult to adapt to the application requirements of high-power illumination.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of emitting uniform polycrystalline sheet encapsulated LED lamp pearl is provided.
The utility model adopts following technical scheme to realize: even light type LED lamp pearl; Include diode wafer, lens, gold thread, pin, packaging plastic, thermal column, pedestal, diode wafer is positioned at the thermal column top and links to each other with pin through gold thread, and lens, pin, thermal column are assembled into one through pedestal; In the cavity that lens and pedestal surround, be filled with packaging plastic; Said lens adopt slab construction, and its surface distributed has a few prisms, and each encloses prism and has the exiting surface of center of circle inclination dorsad; And the diode wafer annular is arranged in the thermal column end face, and lens cover all diode wafers fully.
Further technical scheme is, envelope is changeed the diode wafer that several different capacity sizes are arranged in this LED lamp pearl, and each wafer annular is arranged, and is outside from the center, and the power of each wafer reduces gradually.
The LED lamp pearl of this structure, not only the arrangement of diode wafer is reasonable, and lens arrangement is novel, and both arrange in pairs or groups mutually and can effectively improve the light effect that goes out of lamp pearl, and simple in structure, good heat dissipation effect.
Below in conjunction with accompanying drawing and embodiment the utility model is further set forth, the protection range of the utility model includes but are not limited to accompanying drawing and the disclosed content of embodiment.
Description of drawings
Fig. 1 is the decomposition texture sketch map of the utility model;
Fig. 2 is the structural representation of the utility model lens.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to set forth.
Like Fig. 1, shown in Figure 2, the LED lamp pearl in this specific embodiments includes the center that the diode wafer 1 of two kinds of power, a heavy-duty diode wafer are arranged on thermal column 5 end faces, eight low power diode wafers are evenly spaced be looped around the heavy-duty diode wafer around; Its lens 2 adopt slab construction, and its upper surface is distributed with a few prisms 3, and each encloses prism and has the exiting surface of center of circle inclination dorsad; The thermal column 5 that is fixed with diode wafer penetrates from pedestal 6 bottom surfaces; The end face of pedestal 6 is formed with snap-in structure, and lens 2 inlay cards cover diode wafer 1 fully at the pedestal top; And the arrangement that is distributed in diode wafer 1 of the prism on the lens 3 adapts; Two pins 4 penetrates from the pedestal sidewall, does not contact with thermal column, between pin and the diode wafer; Connect through gold thread, in the cavity that lens and pedestal surround, also be filled with packaging plastic.
Claims (2)
1. even light type LED lamp pearl; Include diode wafer (1), lens (2), gold thread, pin (4), packaging plastic, thermal column (5), pedestal (6); Diode wafer (1) is positioned at the thermal column top and links to each other with pin (4) through gold thread; Lens (2), pin (4), thermal column (5) are assembled into one through pedestal (6), in the cavity that lens and pedestal surround, are filled with packaging plastic, it is characterized in that: said lens (2) adopt slab construction; Its surface distributed has a few prisms (3); Each encloses prism and has the exiting surface that the center of circle dorsad tilts, and diode wafer (1) annular is arranged in the thermal column end face, and lens (2) cover all diode wafers (1) fully.
2. according to the said even light type LED lamp pearl of claim 1, it is characterized in that: envelope is changeed the diode wafer (1) that several different capacity sizes are arranged in this LED lamp pearl, and each wafer annular is arranged, and is outside from the center, and the power of each wafer reduces gradually.
