Description

The LED fixture

Technical field

The utility model relates to a kind of fixture, particularly a kind of LED fixture, and it can avoid solder joint to come off or short circuit, but and has the advantage and an effect of modular applications and ease of assembly.

Background technology

The general at present light fixture that uses high-capacity LED, the fixed form of its LED and heat abstractor generally as shown in Figure 1, normally earlier sentence welding manner solid welding electric wire 20 at the positive and negative electrode contact of LED10, then LED10 is positioned on the heat abstractor 30, passes the default perforation 101 of LED10 metal substrate and directly be locked in heat abstractor 30 with screw 40 again.In addition, if use the light fixture of plurality of LEDs, as shown in Figure 2, though still adopt screw 40 direct locking modes between its LED10 and the heat abstractor 30, electric wire 20 partly then must adopt polyphone wire jumper welding manner.

Yet, in fact have following problem and have to be overcome through looking into above-mentioned LED fixed form:

1, causes short circuit easily: because the fixed form of known LED is to adopt artificial welding manner to finish binding LED and electric wire earlier, and then with screw with LED locking on heat abstractor, though this practice is simple and easy and direct, but easily, artificial welding process cause solder joint excessive because being difficult to control and spotty problem, screw takes place in the locking process then touch solder joint accidentally, and the metallic conduction characteristic of coping screw and cause short circuit phenomenon.

2, solder joint comes off easily: because the mode of connection of known many group LED and electric wire are to adopt polyphone wire jumper mode, therefore after artificial welding is finished, tend to live wire and be across above the metal substrate, even block too complex phenomena generation of circuit such as perforation; And in follow-up locking process, aim at the perforation of metal substrate smoothly for making screw, just must move the electric wire that is across the metal substrate top, thus, as easy as rolling off a log generation causes solder joint to come off because moving electric wire phenomenon.

3, speculum is yielding: general LED light fixture can be looked actual demand and install speculum to produce the shape of not sharing the same light above being chosen in LED; Yet, with the fixed form of known LED, its assembling sequence is to weld electric wire, locking LED more earlier, be only the locking speculum at last, therefore when speculum is fixedly arranged on the heat abstractor end face, be not to lie against the end face of heat abstractor but be pressed against on the mixed and disorderly electric wire, add LED genus high voltage electronic product, its electric wire can not be meticulous, therefore, will cause the speculum buckling deformation again after locking when the reflection static pressure is against on the electric wire, a mistake produces the purpose of not sharing the same light shape.

Because the variety of problems of above-mentioned known LED fixed form, the designer specially designs a kind of LED fixture, and the phase overcomes and addresses the above problem, and is having the utility model to come out through grinding the wound back for a long time.

Summary of the invention

Problem such as the purpose of this utility model is to solve its easy short circuit of known LED fixed form, solder joint easily comes off and speculum is yielding.

For reaching above-mentioned purpose, the utility model mainly provides a kind of LED fixture, comprise a body and pair of conductive sheet, wherein, this body is a lamellar body, its bottom surface moulding one groove, this groove convexes with at least one pair of protruding grain, a pair of perforation is established in body respective slot end, and body end face correspondence is bored a hole and is convexly equipped with a barb, and the barb rear side is also offered a locking hole; This is embedded in the groove of body to conducting strip, conducting strip offers the protruding particle shape one-tenth fixing combination of open-work for groove, conducting strip one end extends to form pin, and this pin passes the perforation of body and is corresponding setting with barb, and the other end of conducting strip then extends to form conductive junction point.

Described LED fixture, wherein, this body has the speculum of optical effect with respect to the other end elongation moulding one of barb, and this conductive junction point is positioned at the junction of body and speculum.

Described LED fixture, wherein, this LED fixture is more than one group, be connected with link plate between every group of LED fixture, and a plurality of this link plate offers locking hole.

A kind of LED fixture, comprise a body and pair of conductive sheet, wherein, this body is a pedestal, empty interval in its central moulding one, should in empty interval front end be the open end and be subjected to the two side and a rear wall around, the relative inner face of its two side is convexly equipped with one respectively and presses piece, press the piece both sides and establish a breach respectively, the bottom surface, two side forms groove, and groove extends to the rear wall of body, and groove convexes with at least one pair of protruding grain, this rear wall is provided with a pair of perforation, and the lateral surface correspondence of rear wall is bored a hole and is convexly equipped with a barb, and rear wall top surface is offered a locking hole in addition; This is embedded in the groove of two side respectively to conducting strip, conducting strip offers the protruding particle shape one-tenth fixing combination of open-work for groove, conducting strip one end extends to form pin, this pin passes the perforation of rear wall and is corresponding setting with barb, and the other end of conducting strip then stretches out the formation conductive junction point from the breach of sidewall.

Advantage of the present utility model is:

1, ease of assembly: because the utility model carries out the fixing and conduction of LED by the structure of body and conducting strip, thus have advantage and the effect that can carry out modular applications and ease of assembly, and need not carry out weld job again and can solve the mixed and disorderly problem of circuit.

2, avoid short circuit: owing to the utility model need not conduct electricity by weld job, so after locked assembly is locked in heat abstractor with the LED fixture, can stop the phenomenon that locked assembly contact solder joint causes short circuit.

3, speculum does not have the worry of distortion: because speculum of the present utility model and body be formed in one and make, and when speculum is arranged at the heat abstractor end face, its bottom surface heat abstractor end face of directly fitting is so nothing is oppressed the worry that electric wire causes speculum to be out of shape.
