The middle part of one end surface of the radiator is an arc-shaped concave; a through hole is formed in the center of the bottom surface of the concave; a circular groove is formed around the mouth part of the through hole; the reflecting cup is fixed in the concave cavity of the radiator; a circular hole for accommodating the LED light source is formed in the center of the bottom surface of the reflecting cup; the LED light source penetrates the circular hole on the reflecting cup and is placed in the circular groove of the radiator, and the bottom surface thereof is adhered to the bottom surface of the circular groove; the LED light source wiring penetrates the through hole in the center of the radiator and is connected with the external drive controller; heat dissipating ribs are arranged on the outer surface of the radiator; and a heat-conducting rubber mat or heat-conducting silicone grease is arranged on the contact surface of the LED light source and the radiator. The LED light cup has the advantages of high heat dissipating efficiency and quick and convenient assembly.

Description

The LED Lamp cup

Technical field

The utility model relates to a kind of LED semiconductor lamp, especially relates to a kind of LED Lamp cup.

Background technology

Traditional incandescent lamp bulb poor efficiency, high power consumption, life-span are short, frangible, though equally also there are problems such as the life-span is short, frangible in fluorescent lamp power saving to a certain extent, especially its discarded object can produce mercury pollution.LED is as a kind of solid light source of novelty, it is almost pollution-free to have production process and product, be not afraid of vibrations, can realize 0 ~ 100% continuous light tuning easily, can under SELV, work, can operate continually at switch dodge disconnected duty with and light output have many special advantages such as directionality, but the heat dissipation problem that how to solve the LED light fixture is an important technology bottleneck that influences its performance.

The utility model content

The technical problems to be solved in the utility model provides a kind of high efficiency and heat radiation, assembles LED Lamp cup easily.

For addressing the above problem, the technical solution of the utility model is for providing a kind of LED Lamp cup, comprise reflector, led light source, radiator, led light source wiring and driving governor, the curved depression in middle part of radiator one end end face, depression bottom center place is provided with a through hole, be provided with a circular trough around the through hole oral area, reflector is fixed in the recessed cavity of radiator, reflector bottom center is provided with the circular port that holds led light source, led light source passes circular port on the reflector and places in the circular trough on the radiator, its bottom surface is attached on the circular trough bottom surface, and the through hole of radiator center is passed in the led light source wiring, is connected with external driving governor.

As improvement of the present utility model, the radiator outer surface is provided with the heat radiation rib.

As another improvement of the present utility model, led light source and radiator contact-making surface are provided with heat conduction rubber cushion or heat-conducting silicone grease.

As further improvement of the utility model, the reflector inwall is provided with sand nickel tangerine line.

As another further improvement of the present utility model, the exit of radiator through hole is provided with the sealing compound that the led light source wiring is fixing.

This LED Lamp cup, the bottom surface of led light source are attached on the bottom surface of circular trough of radiator, and radiator is coated on the reflector outer wall, and the heat of led light source can promptly be distributed.The radiator outer surface is provided with the heat radiation rib, and led light source and radiator contact-making surface are provided with heat conduction rubber cushion or heat-conducting silicone grease, all can further improve radiating effect.The reflector inwall is provided with sand nickel tangerine line, makes reflector have better light reflective properties.

Description of drawings

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.

Fig. 1 is the front three-dimensional structure diagram of the utility model LED Lamp cup;

Fig. 2 is the back side three-dimensional structure diagram of the utility model LED Lamp cup;

Fig. 3 is the three-dimensional exploded view of the utility model LED Lamp cup;

Fig. 4 is the cutaway view of the utility model LED Lamp cup.

Among the figure: 1, radiator, 2, led light source, 3, reflector, 4, screw, 5, the led light source wiring.

The specific embodiment

As Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, LED Lamp cup of the present utility model comprises reflector 3, led light source 2, radiator 1, led light source wiring 5 and driving governor, the curved depression in middle part of radiator 1 one end end faces, depression bottom center place is provided with a through hole, be provided with a circular trough around the through hole oral area, reflector 3 is fixed in the recessed cavity of radiator 1, reflector 3 bottom center are provided with the circular port that holds led light source 2, led light source 2 passes circular port on the reflector 3 and places in the circular trough on the radiator 1, its bottom surface is attached on the circular trough bottom surface, the through hole of radiator 1 center is passed in led light source wiring 5, be connected with external driving governor, the led light source 2 in the present embodiment is single 3W.

Led light source 2 sticks in by force in the circular trough of radiator 1 through hole oral area by heat conduction rubber cushion or heat-conducting silicone grease, and after led light source wiring 5 passed in the centre bore, the embedding chewing-gum was fixed in the oral area of radiator 1, prevents that the external world from haling electric wire and causing and come off.

Radiator 1 is an aluminum alloy material, adopts the section bar drawing and forming, and outer surface is provided with whole circle heat radiation rib, and heat conduction is fast, and area of dissipation is big.Simultaneously, on radiator 1, also stretch two screwed holes are arranged.

Reflector 3 light-emitting window places are provided with export-oriented bending edges, the bottom surface presents interior to bending shape, have the plane after the bending of one's own, the bottom center place has the circular port that holds led light source 2, around circular port, also have two small sircle holes, corresponding with two screwed holes on the radiator 1, reflector 3 relies on screw 4 and above-mentioned hole to be locked on the radiator 1.Reflector 3 inwalls are made sand nickel tangerine line and are handled, and light reflective properties is good, and reflector 3 is 30 ° of angle luminous intensity distribution designs with light source.

Ad hoc structure described in above embodiment and the relevant drawings is interpreted as illustrating of the present utility model, and should not be construed restriction of the present utility model.
