Abstract
An LED down lamp comprises a shell body and an aluminum substrate, and a plurality of LEDs are arranged on the aluminum substrate. Each LED is mainly composed of a wafer, metal wires and a support, wherein the support is a heat sink type surface-mounted support, the wafer is fixed to the support through fluorescent glue, support pins are arranged at the two sides of the support, and the wafer is connected with the support pins through the metal wires. The LED down lamp adopts the high-luminous-efficiency hotspot separative power type LEDs to replace lamp beads used by the LED down lamp, so that a heat dissipation structure of the LED down lamp is met more easily, and the heat dissipation effect of the down lamp is improved. The LED down lamp adopts a thermoelectricity separating design, is provided with a unique heat passage and an electric passage, can achieve the good heat dissipation effect without heat-conducting glue or a heat-conducting silicon pad, is high in reliability, is low in luminance decrease, is longer in service life, largely reduces the number of the lamp beads, improves the surface-mounting efficiency, uses a light source bonding pad with a large area, lowers the reject ration of surface mount devices, and improves production efficiency. A light source and the aluminum substrate are perfectly combined, so that light is emitted more evenly.
Description
Technical field
The utility model relates to lighting technical field, is specifically related to a kind of LED Down lamp that adopts high light efficiency thermoelectricity separative power type light-emittingdiode.
Background technology
Along with the progress of electronic technology, utilize LED Down lamp more and more general, LED Down lamp especially, LED Down lamp is by beautiful outward appearance, and simple mounting means, and good illuminating effect, be widely used in the places such as commercial lighting, lighting of home.
Along with large-scale popularization and the application of LED Down lamp, also expose gradually their many weak points: the heat radiation of (1) LED Down lamp is concentrated, and heat sink material volume is too large, causes high cost, and product cost performance is low; (2) LED Down lamp non-uniform light, causes hot spot to produce, and affects illuminating effect.
In order to address the above problem, LED Down lamp adopts and changes the method that shell mechanism improves radiating efficiency, and still this method is but cured the symptoms, not the disease, and can not fundamentally solve its technical problem.
Utility model content
The utility model provides a kind of LED Down lamp, the lamp pearl that adopts high light efficiency thermoelectricity separative power type light-emittingdiode to replace LED Down lamp to use, the problem that radiating efficiency is low, luminous efficiency is poor and illumination effect is bad existing to solve prior art.
The utility model comprises housing and aluminium base, solving the technical scheme that its technical problem adopts is that some light-emittingdiodes are set on aluminium base, light-emittingdiode is mainly by wafer, gold thread and support form, support is heat sink formula patch support, support is fixed on wafer on support by fluorescent colloid, and support both sides are provided with support pin, and wafer is connected with support pin by gold thread.
Above-mentioned gold thread is 99.99% high-purity gold thread, and support pin is large area pad.
Above-mentioned housing is frosted lampshade, and light transmittance is between 78%～85%.
The utility model is by adopting monocrystalline, thermoelectricity separate design, there is high light efficiency, unique thermoelectricity passage, the lamp pearl that high light efficiency focus separative power type light-emittingdiode simple in structure, radiating effect replaces LED Down lamp to use, more meet the radiator structure of Down lamp, improves the radiating effect of Down lamp; Thermoelectricity separate design, the unique passage of heat and electric channel, whole lamp just can reach good radiating effect, high reliability, low light attenuation, longer service life without heat-conducting glue and thermal conductive silicon pad; A large amount of lamp pearl quantity that reduces, improves paster efficiency, and light source bonding pad area used is larger, reduces paster fraction defective, enhances productivity; Light source and aluminium base perfect adaptation, luminous more even.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model light-emittingdiode.
1 housing, 2 aluminium bases, 3 light-emittingdiodes, 31 wafers, 32 gold threads, 33 fluorescent colloids, 34 support pins, 35 supports in figure.
The specific embodiment
As depicted in figs. 1 and 2, a kind of LED Down lamp, comprise housing 1 and aluminium base 2, housing 1 is frosted lampshade, light transmittance is between 78%～85%, some light-emittingdiodes 3 are set on aluminium base 2, light-emittingdiode 3 is mainly by wafer 31, gold thread 32 and support 35 form, and support 35 is heat sink formula patch support, and support 35 is fixed on wafer 31 on support 35 by fluorescent colloid 33, support 35 both sides are provided with support pin 34, wafer 31 is connected with support pin 34 by gold thread 32, and gold thread 32 is 99.99% high-purity gold thread, and support pin 34 is large area pad.
