Abstract

The invention discloses an LED lamp which comprises a lamp holder, a heat radiator, an electronic assembly and an LED lamp panel, wherein the lamp holder is connected with the heat radiator through a base, and the electronic assembly is arranged in an inner cavity formed by connecting the lamp holder with the heat radiator. The LED lamp is characterized in that the outer wall of the base is provided with a limit convex ring and a fixed groove, the limit convex ring is matched with the end face of a narrow hole of the heat radiator, the inner wall of the narrow hole end of the heat radiator is provided with a buckle ring, the buckle ring is matched with the fixed groove on the base; and the LED lamp panel is fixed on the opened end face of the heat radiator through a PC screw. The lamp holder and the heat radiator are connected through the base provided with the limit convex ring and the fixed groove, thus the connection part of the lamp holder and the heat radiator is avoided loosening and the use stability of the lamp is improved, the service life of the lamp is prolonged; meanwhile, the LED lamp panel and the heat radiator are fixed by using the PC screw for replacing the traditional metal screw, thus the short circuit caused by small distance between the screw and an LED is eliminated.

Description

The LED lamp

Technical field

The present invention relates to a kind of light fixture, particularly the LED lamp.

Background technology

At present, mostly the indoor or outdoors lighting that is widely used is incandescent light bulb or fluorescent tube, all lower but the electric light of these two kinds of products dress changes efficient, and caloric value is big, and service life is shorter.

The LED lighting engineering is through years of development and accumulation; Shown outstanding energy-saving effect; Led light source is as a kind of emerging semiconductor light-emitting elements, advantage such as have that volume is little, power consumption is low, caloric value is low and the life-span is long, so the light fixture in LED lamp source is used widely.

The lamp holder of LED light fixture and radiator is fixedly connected for ease; All can adopt a base to fix lamp holder and radiator in the LED fitting structure on the market now, but said structure is in convenient lamp holder and radiator installation, because lamp holder is not directly to be connected with radiator; In use for some time; Loosening phenomenon will appear in the junction of lamp holder and radiator, and in the service life of the whole lamp of influence, this is a technological deficiency during present stage LED light fixture is produced; Also has present widely used LED light fixture; Its LED substrate and radiator are often directly fixed through the metal screw, because metal conducts electricity the characteristic of heat conduction easily; And the metal screw is near excessively from led light source when installing, and can cause LED short circuit phenomenon in use to occur.

Summary of the invention

The objective of the invention is provides a kind of stability in use high for the deficiency that solves above-mentioned prior art, and can avoid the LED lamp plate LED lamp of short circuit phenomenon in use to occur.

To achieve these goals, the LED lamp that the present invention designed comprises lamp holder, radiator, electronic building brick and LED lamp plate; Lamp holder is connected with radiator through base; The inner chamber that electronic building brick places lamp holder to be connected with radiator and to form is characterized in that said base outer wall is provided with position limiting convex ring and holddown groove, and position limiting convex ring cooperates with the slot end face of radiator; Radiator slot end inwall is provided with clasp, and clasp cooperates with holddown groove on the base; Said LED lamp plate is fixed on the uncovered end face of radiator through the PC screw.

Stability in use of the present invention is high, and can avoid the LED lamp plate short circuit phenomenon in use to occur.

Outside the LED lamp plate, also can be provided with lampshade, the opening end of radiator is connected with the openend buckle of lampshade.

The LED lamp that the present invention obtains, its lamp holder is connected through the base that has position limiting convex ring and holddown groove with radiator, avoids the junction of lamp holder and radiator loosening phenomenon to occur, and the stability in use of whole lamp is improved, and increases the service life; Replace traditional metal screw to fix through the PC screw between LED lamp plate and the radiator simultaneously, solved the short circuit phenomenon that screw excessively closely causes from LED.

Description of drawings

Fig. 1 is the overall structure exploded perspective view of embodiment 1;

Fig. 2 is the overall structure cutaway view of embodiment 1;

Fig. 3 is the local enlarged diagram of Fig. 2.

Among the figure: lamp holder 1, base 2, position limiting convex ring 21, holddown groove 22, radiator 3, uncovered end face 31, slot end face 32, clasp 33, electronic building brick 4, lead 41, LED lamp plate 5, lampshade 6, PC screw 7.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is further specified.

Embodiment 1:

Like Fig. 1, Fig. 2, shown in Figure 3; The LED lamp that present embodiment provides comprises lamp holder 1, radiator 3, electronic building brick 4, LED lamp plate 5 and lampshade 6, and lamp holder 1 is connected with radiator 3 through base 2; The inner chamber that electronic building brick 4 places lamp holder 1 to be connected with radiator 3 and to form; The opening end of radiator 3 is connected with the openend buckle of lampshade 6, and the outer wall of base 2 is provided with position limiting convex ring 21 and holddown groove 22, position limiting convex ring 21 cooperate with the slot end face 32 of radiator 3 carry out spacing; The slot end inwall of radiator 3 is provided with clasp 33, and clasp 33 cooperates with holddown groove 22 on the base 2 to be fixed; LED lamp plate 5 is fixed on the uncovered end face 31 of radiator 3 through PC screw 7.

Stability in use of the present invention is high, adopts heat resistance to replace traditional metal screw to make LED lamp plate 5 in use can avoid occurring short circuit phenomenon greater than the PC screw 7 of 120 degree, and it is masterly that LED lamp plate 5 is used under febrile state.

When concrete the installation; The slot end that has base 2 end insertion radiator 3 of holddown groove 22 earlier; The position limiting convex ring 21 that is inserted on the base 2 withstands till the slot end face 32 of radiator 3; This moment radiator 3 inwalls clasp 33 also just with base 2 on holddown groove 22 fixing, base 2 and radiator 3 are fixed; Lead 41 on next electronic building brick 4 is welded to lamp holder 1 inwall, then electronic building brick 4 is placed from the slot end of radiator 3 and is entered into radiator 3 inner chambers, and being right after a step is exactly to get lamp holder 1 ready to be fixed on the base 2; At last LED lamp plate 5 is electrically connected with electronic building brick 4, is fixed to the unlimited end face 31 of radiator 3 to LED lamp plate 5 usefulness PC screws 7, cover lampshade 6.

Because the technique for fixing of getting ready in above-mentioned is the known technology in the LED lamp production field, therefore is not described in detail at this.
