Abstract
The utility model relates to an energy-saving LED bulb. The energy-saving LED bulb comprises a lamp cap, a plastic housing, a fixing ring and a glass cover, wherein a control circuit board and a lampwick body connected with the control circuit board are arranged in the plastic housing; and direct-embedded LED devices are uniformly mounted at the periphery of the lampwick body. The energy-saving LED bulb can achieve good heat dissipation effect through the heat radiation of the light emitting devices, the lampwick body and the fixing ring, thereby prolonging the service life of the LED devices. In addition, the pins of two adjacent light emitting devices pass through the same via-hole so as to reduce the number of via-holes on the substrate; and the pins are gathered to facilitate the connection operation, thereby enhancing the reliability of the circuit connection and simplifying the structure.
Description
Technical field:
The utility model relates to a kind of bulb, relates in particular to a kind of LED energy-saving bulb.
Background technology:
LED (Light Emitting Diode) is a semiconductor light-emitting-diode, is to utilize semi-conductive P-N knot to produce a kind of solid luminescence device of carrier recombination luminescence under the forward voltage effect.The technological break-through of high-brightness white-light LED and in the successful Application of lighting field is described as human great again illumination revolution after Edison's invention electric light.LED has the light efficiency height, power consumption is little, energy-saving efficiency is high (actual consumption be about incandescent lamp 1/10, electricity-saving lamp 1/2), long (can reach more than 100,000 hours), environment friendly and pollution-free (power saving fluorescent lamps etc. all have mercury pollution) of life-span, do not avoid frequent switch, volume is little, in light weight, sound construction is shatter-proof and once turning on light numerous advantages such as reaching maximum brightness immediately.LED has been widely used in fields such as all kinds of demonstrations, LCD back lighting, automobile-used light source, Landscape Lighting, decorative lighting, road lighting and indoor general lighting, is the light source product of present international forefront.
Yet LED makes slow progress in above-mentioned automobile-used illumination and room lighting at present, exists in its practical application " bottleneck ".Because people will concentrate on great power LED, problem is difficult to solve at present and the light efficiency that its heat dissipation problem causes descends, light decay is accelerated, the life-span shortens etc., so that serious its application of restriction.
Summary of the invention:
The purpose of this utility model has been to provide a kind of simple in structure, radiating effect is good and long service life is energy-efficient LED energy-saving bulb.
To achieve these goals, the utility model provides a kind of LED energy-saving bulb, comprise lamp holder, plastics lamp housing, retainer ring and cloche, in the plastics lamp housing, control circuit board is arranged, and the sans serif that links together with control circuit board, direct insertion LED luminescent device evenly is installed around sans serif.
Further, described sans serif be shaped as cylindric.
Further, the insulated substrate of described direct insertion LED luminescent device adopts solid insulating material, and the heat conduction encapsulated layer adopts cement.
Further, described direct insertion LED luminescent device pipe leg adjacent one another are is identical from the position that insulated substrate passes.
Advantage of the present utility model is: the LED luminescent device is provided with three grades of radiators: illuminator is installed in forms the direct plug-in type light emitting device on the insulating heat-conductive layer, the direct plug-in type light emitting device has become first order radiator; The direct plug-in type light emitting device tightly is installed in again on the sans serif, and sans serif is a second level radiator; Sans serif is installed on the retainer ring, and retainer ring becomes third level radiator; Reach better heat radiating effect like this, prolonged LED luminescent device working life.And, the public hole of the pin of adjacent two illuminators passed, reduced the quantity of substrate perforation, and pin flocks together, made things convenient for attended operation, the reliability that the circuit of increase connects has characteristic of simple structure.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is 7 a vertical view among Fig. 1.
Fig. 3 is 8 a front view among Fig. 2.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1, the utility model LED energy-saving bulb screws in lamp socket by lamp holder 12 and is electrically connected with the city, lamp holder 12 is connected with control circuit board 10 by two leads, control circuit board 10 is connected with LED sans serif 7 by two leads, sans serif 7 is fixed together with retainer ring 9, usefulness dedicated lamp is gluing is connected together for cloche 6 and retainer ring 9, and retainer ring 9 and plastics lamp housing 11 are by being threaded, and plastics lamp housing 11 and lamp holder 12 rivet together.
As Fig. 2, shown in Figure 3, six direct insertion LED luminescent devices 8 evenly are installed around sans serif 7, the structure of direct insertion LED luminescent device 8 is respectively illuminator 2 from outside to inside, insulated substrate 1 and heat conduction encapsulated layer 3, illuminator 2 is positioned at insulated substrate 1 one side, luminescent device pipe leg 4 passes in insulated substrate 1 corresponding aperture, two public holes of adjacent LED luminescent device, passing LED luminescent device pipe leg 4 uses tinplate to make sleeve 5, use crimping tool to carry out Cold welding or carry out hinged, realize the electrical connection between each adjacent LED luminescent device in the LED light-emitting element array, high temperature consume when having avoided the welding of LED luminescent device cooperates crimping or articulated tool to improve production efficiency simultaneously and reduces cost; The another side corresponding with illuminator 2 covers the heat conduction encapsulated layer 3 that one deck is made by the cement encapsulation, increases the product heat-sinking capability, reached better heat radiating effect, prolonged LED luminescent device working life.
