Description
Technical field
The present invention relates to LED shot-light technical field, particularly lamp holder and the holder structure used of a kind of LED shot-light of external constant-current driving power supply.
Background technology
LED-MR16 shot-light is compared halogen spot light and is had advantage low in energy consumption, that heat is little, the life-span is long, and light efficiency is 5 times of halogen spot light, and replacing halogen spot light with LED-MR16 shot-light will be trend of the times.The power of existing LED-MR16 shot-light (standard shape size) is generally all less than 4W, and its dc constant flowing power is placed in the Lamp cup the inside, through the lamp holder insertion lamp socket of Lamp cup, by the power line connection power supply of lamp socket.The power supply of power supply all is the electronic transformer that adopts Halogen lamp LED to use, and electronic transformer is actually a kind of inverter and non-voltage regulation type Switching Power Supply, and output voltage is AC7-12V, and frequency is 20-25KHZ, and power is the high-frequency alternating current of 10-50W.And built-in dc constant flowing power in LED-MR16 shot-light cup, its effect is to export needed voltage through Switching Power Supply, does the secondary rectification then and supplies with to LED and use.The electronic transformer that the employing Halogen lamp LED is used has following shortcoming as the power supply of LED-MR16 shot-light: the highest AC12V of having only of electronic transformer output voltage that (1) is used owing to Halogen lamp LED, for example, when the led chip series connection of 4 * 1W is used; The normal operating voltage of LED should be greater than DC13V; At this moment the output voltage of electronic transformer is the requirement that can't satisfy LED, only if when the secondary rectification elder generation's rising input ac voltage, could obtain needed dc voltage value then; But this method cost is very high; And the individual elements caloric value is big, and used element is many and take up space greatly, and the LED radiator is difficult in Lamp cup, be provided with.(2) electronic transformer used of Halogen lamp LED generally is by 10-50W power designs; And the power of most LED-MR16 shot-light has only 1-4W; The power that is to say load is less than 1/10 of electronic transformer rated power; The magnetizing current that in the half-bridge commutating circuit of electronic transformer, produces is not enough, makes electronic transformer be in abnormal state work and makes the LED lamp phosphere intermittently occur.(3) dc constant flowing power of generally using at the built-in LED of Lamp cup all is connected to a very big electrolytic capacitor filter at its rectification bridge output end; Be about 220 μ F; Being equivalent to for Halogen Lamp Electronic Transformer that load becomes by original pure resistive load is a capacitive load, thereby makes electronic transformer be in off-mode and cisco unity malfunction.This shows; The electronic transformer that Halogen lamp LED is used is applied to LED-MR16 shot-light; Its duty is highly undesirable, and it can't improve the serviceability and the illuminating effect of LED shot-light, also is not suitable for for the LED shot-light power supply of using with the series connection of plurality of LEDs chip; Thereby, be difficult to the power of LED-MR16 shot-light is increased to 15W.
Summary of the invention
The lamp holder and the holder structure that the object of the present invention is to provide a kind of LED shot-light of external constant-current driving power supply to use; It is designed to a kind of lamp holder latch that can distinguish anodal and negative pole and a kind of can not transposition and the lamp socket of band positive and negative electrode socket, guarantee the correct direct current constant current power supply of LED acquisition in the Lamp cup.
The technical solution that the present invention proposes is such:
Lamp holder and holder structure that a kind of LED shot-light of external constant-current driving power supply is used; Comprise Lamp cup and be positioned at the lamp holder at Lamp cup rear portion; Said lamp holder rearward end is provided with anodal latch and negative pole latch, and said anodal latch shape of cross section is different with negative pole latch shape of cross section; Also be provided with the lamp socket of band positive and negative electrode jack; This lamp socket is provided with lamp holder, latch metal contact and compressing tablet; Said lamp holder is provided with two cavitys; The outside latch metal contact of opening is housed in each cavity and between chamber wall and latch metal contact, stage clip is housed, the said compressing tablet that is provided with anodal jack and negative pole jack is packed on the lamp holder front end face, anodal jack and negative pole jack respectively with two cavitys in latch metal contact opening corresponding one by one; The anodal latch of said lamp holder and negative pole latch are pegged graft with the anodal jack and the negative pole jack coupling of compressing tablet respectively, and said two latch metal contact rear sections are not welded with positive wire and cathode conductor.
The shape of cross section of said lamp holder negative pole latch is the rectangle of rectangle or long sideband arc.The shape of cross section of the anodal latch of lamp holder is circle or square or regular polygon.The negative pole jack of compressing tablet is shaped as the rectangle of rectangle or long sideband arc, with the identical and coupling of shape of cross section of corresponding negative pole latch.
The anodal jack of said compressing tablet is shaped as circle or square or regular polygon, with the identical and coupling of shape of cross section of corresponding anodal latch.The lamp holder fixation spring tab is housed, this shell fragment and the socket connection of lamp holder elasticity on the lamp holder.
Compared with prior art, the present invention has following remarkable result:
(1) lamp holder of existing LED-MR16 shot-light and holder structure are that two metal bolt of lamp holder are cylinder, and diameter is identical with length, after the latch of lamp holder inserts lamp socket, can't pick out positive and negative electrode, and the direction of insertion can be exchanged.The LED of existing standard appearance and size-MR16 shot-light is owing to will adopt external Halogen Lamp Electronic Transformer to supply power to supply power and use to LED to being built in direct current constant current working power in the Lamp cup; To not design and manufacture the dc source ten minutes difficulty that satisfies the LED requirement because of the power quality of electronic transformer is good with direct current constant-current driving power supply limited space in Lamp cup, so the power of existing LED shot-light all can not be greater than 4W.The present invention is owing to the shape that has changed two latch cross sections of lamp holder fully and different; The shape of two jacks of lamp socket matches through the positive and negative electrode jack of compressing tablet; Thereby in installing and using, can pick out positive and negative electrode fully, guarantee that the LED in the shot-light obtains correct dc supply.
(2) lamp holder that the present invention adopted and holder structure; Owing to used external direct current constant-current driving power supply; So the volume of this direct current constant-current driving power supply does not receive spatial constraints basically, thereby than being easier to design and manufacture the quality power that meets the LED instructions for use.
(3) the interior space of Lamp cup increased a lot after LED of the present invention-MR16 shot-light used external direct current constant-current driving power supply; Can increase the area of dissipation of its LED radiator; Help heat radiation; Or in cup, load onto the heat radiation that the fan of forcing air draft is used for LED on the LED radiator, like this can be with the power that has the LED shot-light now by bringing up in the 15W less than 4W.
(4) LED shot-light manufacturing process of the present invention is simple, easy to install and the lamp socket installation dimension is general, patches dc supply and can not make mistakes, and production efficiency is high, cost is lower.
The present invention is applicable to that mainly LED-MR16 shot-light uses.
