Description
Technical field
The utility model relates to a kind of lamp decoration, especially a kind of high light efficiency LED candle lamp.
Background technology
Owing to adopt candle as light emitting source, in use exist certain disaster hidden-trouble, so electric light occurred, its illuminator generally is the vacuum bulb that adopts tungsten filament, and the problem that this illuminator exists is that power consumption is big, and service life is short.
Because the LED lamp is a cold light source, photochromic soft, free from glare contains some pernicious gases (as containing poisonous mercury vapour in the electricity-saving lamp) unlike other light source, and the recyclable utilization of LED waste products, is a kind of green energy conservation product; Also be that a kind of high hardness resin illuminator but not tungsten filament glass etc. damage light source easily, so seismic force is higher relatively, the environment temperature adaptive faculty is strong, and starts soon, and power is little, and no stroboscopic is not easy visual fatigue, so the LED lamp is widely used in the every field.
The a lot of employing LED lamps that occur now are as the candle lamp of illuminator, the both energy savings of this LED lamp, long service life again.But, the led chip of existing LED lamp is to be welded on the pcb board, the heat radiation approach of whole high light efficiency LED candle lamp is: outside LED → pcb board (aluminium base) → thermal conductive insulation glue → metal shell → lamp body, though metal substrates such as aluminium base have very good heat conductivility and high-intensity electrical insulation properties, but the heat radiation approach is oversize, the heat that LED produces is difficult for getting rid of, cause the LED junction temperature to raise, the rising of LED junction temperature can make transistorized current amplification factor increase sharply, cause collector current to increase, junction temperature is further raise, finally cause LED to lose efficacy.In addition, the high light efficiency LED candle lamp is under the high temperature work for a long time, can cause bad phenomenon such as insulating properties degeneration, components and parts damage, the heat ageing of material, low melting point weld cracking, the solder joint of candle lamp come off.Therefore, be necessary the high light efficiency LED candle lamp is improved, with further enhancing radiating effect.
Summary of the invention
The purpose of this utility model provides a kind of good heat dissipation effect, luminous efficiency height, energy-conservation high light efficiency LED candle lamp.
For achieving the above object, the technical scheme that the utility model adopted is:
A kind of high light efficiency LED candle lamp, comprise lamp housing, led chip, radiating piece and lamp holder, the shape that is shaped as combustion flame of described lamp housing, led chip and radiating piece are located in the lamp housing, have groove on radiating piece, and led chip is located in the groove, be bonded by thermal conductive insulation glue between led chip and the radiating piece, be provided with the led chip solder joint in the both sides of groove, this led chip solder joint is located on the radiating piece, and the two poles of the earth of led chip are connected with the led chip solder joint by bonding wire respectively.
Described groove be shaped as circular arc.
Described lamp holder is a lamp screw base.
The two poles of the earth of described led chip are connected with the led chip solder joint by gold thread respectively.
Described led chip has six, and they evenly distribute on the radiating piece.
After the utility model adopts said structure, by directly being encapsulated in led chip on the radiating piece, the existing high light efficiency LED candle lamp of the high light efficiency LED candle lamp of this structure is compared, existing candle lamp is " LED → pcb board (aluminium base) → thermal conductive insulation glue → metal shell → lamp body is outer " heat radiation approach, and the heat radiation approach of high light efficiency LED candle lamp of the present utility model is " LED and metal heat sink firming body → lamp body are outer ", the step of only need dispelling the heat together just can solve the heat dissipation problem of high light efficiency LED candle lamp.The light fixture good heat dissipation effect of this structure, the temperature when effectively reducing led chip work can improve LED colour rendering, luminous efficiency and service life effectively.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 partly cuts open structure chart for the utility model;
Fig. 2 is the enlarged drawing of the utility model led chip and metal heat sink.
Among the figure: 1 lamp housing, 2LED chip, 3 radiating pieces, 31 grooves, 4 lamp holders, 5 thermal conductive insulation glues, 6LED chip welding spot, 7 bonding wires.
The specific embodiment
Shown in Fig. 1 and 2, high light efficiency LED candle lamp of the present utility model, comprise lamp housing 1, led chip 2, radiating piece 3 and lamp holder 4, the shape that is shaped as combustion flame of lamp housing 1 wherein, led chip 2 and radiating piece 3 all are located in the lamp housing 1, on radiating piece 3, have groove 31, led chip 2 is located in the groove 31, be bonded by thermal conductive insulation glue 5 between led chip 2 and the radiating piece 3, be provided with led chip solder joint 6 in the both sides of groove 31, this led chip solder joint 6 is located on the radiating piece 3, and the two poles of the earth of led chip 2 are connected with led chip solder joint 6 by bonding wire 7 respectively.In the present embodiment, groove 31 is shaped as circular arc.Lamp holder 4 adopts lamp screw base, adapts with existing light fixture head.Preferably the two poles of the earth of led chip 21 are connected with led chip solder joint 24 by gold thread respectively.In the present embodiment, adopt six led chips 2, they evenly distribute on the radiating piece 3.The P of led chip 2, the N utmost point are by playing the gold thread connection or deciding machine group with group and decide to require to make copper foil circuit according to actual production on metal heat sink then to led chip solder joint 6.
Take the high light efficiency LED candle lamp of this structure, led chip 2 becomes one with metal heat sink 3.Compare with " LED → pcb board (aluminium base) → thermal conductive insulation glue → metal shell → lamp body is outer " heat radiation approach of traditional LED lamp, adopt the heat radiation approach of high light efficiency LED candle lamp of the present utility model to be " LED and metal heat sink firming body → lamp body are outer ", the step of only need dispelling the heat together, just can solve the heat dissipation problem of high light efficiency LED candle lamp, therefore, the light fixture good heat dissipation effect, the temperature when effectively reducing led chip work can play good effect to improving LED light efficiency and life-span.
