Abstract

The utility model relates to a light source, in particular to an LED light source which can completely replace the ALR111 type halogen lamp, including a front cover, a lens, an LED lamp, a cooling rear tube, a fixing cover, a drive power supply power, a reflective cover, and a lamp holder, wherein, the reflective cover and the lamp holder are components of the ALR111 type halogen lamp, the lower part of the drive power supply is designed with electric connection pins matched with the lamp holder, the upper of the drive power supply is designed with electric connection pins contacted with the lower bottom surface of the heat radiation rear barrel, the heat radiation rear barrel is made from metal, the middle part area of the lower bottom surface is stuck with an electric connection piece insulated with the heat radiation rear barrel. The LED lamp and the drive power supply of the light source are energized by contact of electric connection spring needles, rather than electrical wires, so that the replacement of LED lamp can be convenient.

Description

A kind of light source

Technical field

The utility model relates to a kind of light source, and finger can substitute the led light source in the various floodlights of being installed in of 111 millimeters aluminium reflectors of Φ Halogen lamp LED especially.

Background technology

111 millimeters aluminium reflectors of Φ Halogen lamp LED is as the light source of floodlight, be widely used in the commercial lighting in hotel, market, its power is generally at 50W to 100W, service life is generally at 2000h, beam angle is spent to 24 degree 8, the problem that its highly energy-consuming and caloric value are high is well-known, but suffers from the special tectonic of 111 millimeters aluminium reflectors of Φ light fixture and good beam angle, makes existing energy-conserving light source to substitute.

Summary of the invention

The purpose of this utility model is to release a kind of new led light source, and its structure is fit to existing 111 millimeters aluminium reflectors of Φ light fixture fully, has good beam angle, and 111 millimeters aluminium reflectors of Φ halogen light source is substituted by energy-conserving light source becomes possibility.

The technical solution of the utility model is as follows:

A kind of light source, comprise tube after reflector, lamp socket, driving power, the heat radiation, LED lamp, lens, fixed cover, protecgulum, wherein, reflector and lamp socket still adopt the original fitting of 111 millimeters aluminium reflectors of Φ Halogen lamp LED, the input of driving power is designed to contact pin, peg graft with lamp socket, the output of driving power is designed to two and connects electricity bullet pin; Fixed cover is manufactured with metal, and its two ends are connected on the sidewall of reflector, and there is internal thread in fixed cover central authorities ringwise; Heat radiation back tube is manufactured with metal, a power connecting sheet is fixed in the bottom, between power connecting sheet and the heat radiation back tube dielectric is arranged, to play pin corresponding with connecing electricity in the position of power connecting sheet, having a lead-out wire to pass heat radiation back tube bottom on the power connecting sheet is connected with a pin of its inner LED lamp, another pin of LED lamp joins with heat radiation back tube, and like this, power connecting sheet and heat radiation back tube just become two electrodes of LED lamp; Heat radiation back tube has external screw thread, can directly screw in the internal thread of fixed cover central rings, makes power connecting sheet and heat radiation back tube connect electricity with two outputs of driving power respectively and plays the pin crimping; Protecgulum is manufactured with metal, and internal thread is arranged, and protecgulum is enclosed within on the lens, covers on nozzle after the heat radiation then to screw, and LED lamp and lens just are fixed in the cavity of protecgulum and heat radiation back tube composition.

The beneficial effects of the utility model are: can be replaced by led light source to the light source in 111 millimeters aluminium reflectors of various Φ halogenic lamps and lanterns easily, new lamp more just can reach the target of energy-conservation high light efficiency.
