Description

A kind of led light source enhancing device

Technical field

The utility model relates to a kind of LED lighting engineering, and more particularly, it relates to a kind of led light source enhancing device that is used to improve the led light source illuminating effect.

Background technology

In the above super-high-power LED lighting of hectowatt, its illuminator all is the chip that has the PN junction crystal by a plurality of, combines with the circuit connecting mode of series and parallel.What generally use in existing market is luminescent crystal individual packages technology, and adopts a plurality of independent components, by the series parallel circuits combination of outside, forms the matrix form light source that is commonly called as, and realizes the super high power of light fixture.Though single illuminator light efficiency is high slightly, radiating condition is better, but has the deficiency that element apolegamy difficulty is big, the apolegamy spare part is many, cost is high, the technology contact is many, and the large-power lamp of forming also exists electric harmony poor, the fault rate height influences the reliability and stability of light source; In addition, the illuminator that utilizes independent component to form, its combination area of arranging is big, has limited the moulding and the adaptability of light fixture, also is unfavorable for the performance of LED advantage.Inventor of the present utility model is at this situation, develop and utilize the essentially identical LED crystal grain of a plurality of electric parameters, circuit structure by series and parallel, directly be combined in a plurality of LED crystal grain on the heat-conducting substrate, form the integrated packaged LED module of super high power, solve the problems referred to above, on this basis, more proposed a kind of synergy structure that improves the led light source light efficiency.

The utility model content

The technical problems to be solved in the utility model is the above-mentioned deficiency at prior art, and a kind of simple in structure, led light source enhancing device that can improve illuminating effect is provided.

The technical solution of the utility model is such: a kind of led light source enhancing device, comprise heat-radiating substrate, wherein said heat-radiating substrate surface is provided with two outward-dipping inclined-planes, two inclined-planes are the symmetric arrays of forming V-shape, the led module of two equal-wattages is housed respectively at two chamfered surfaces, be respectively equipped with reflection shield in two led module outsides, between two led modules, be provided with the center and divide light reflecting board.

In above-mentioned a kind of led light source enhancing device, the tilt angle alpha of described two inclined-planes and heat-radiating substrate is 30～35 °.

In above-mentioned a kind of led light source enhancing device, the described reflection shield outside is provided with light-passing board, is used for the proofing dust and protecting of led module.

After the utility model adopted said structure, by led module is installed on the inclined plane, the secondary optics control that utilizes reflector and center to divide light reflecting board to realize light was controlled at light in the scope that needs, and improves the service efficiency of light; Both can solve the shortcoming that led module is dazzle the eyes, can improve the uniformity of irradiation brightness and irradiation more than 30% again.

Description of drawings

Below in conjunction with the embodiment in the accompanying drawing the utility model is described in further detail, but does not constitute any restriction of the present utility model.

Fig. 1 is the structural representation of a kind of specific embodiment of the utility model;

Fig. 2 is the upward view of Fig. 1.

Among the figure: light reflecting board 5, light-passing board 6 are divided in heat-radiating substrate 1, inclined-plane 2, led module 3, reflection shield 4, center.

The specific embodiment

Consult Fig. 1, shown in Figure 2, a kind of led light source enhancing device of the present utility model comprises heat-radiating substrate 1, is provided with two outward-dipping inclined-planes 2 on heat-radiating substrate 1 surface, two inclined-planes 2 are the symmetric arrays of forming V-shape, and two inclined-planes 2 are good with the tilt angle alpha of heat-radiating substrate 1 with 30～35 °; The led module 3 of two equal-wattages is housed respectively on 2 surfaces, two inclined-planes, and led module 3 adopts the super-high-power LED light source of integrated encapsulation, is respectively equipped with reflection shield 4 in two led module 3 outsides, and light reflecting board 5 is divided at the center that is provided with between two led modules 3; The effect of reflection shield 4 is the service efficiencies that improve light in the utility model, and can be according to the distribution of light and the illumination requirement of shadow surface, set the geometry and the light refraction angle of reflection shield 4, light is effectively projected on the area that needs irradiation, also can project on the area of needs projection after thereby the light that makes the radiation of light source angle surmount projection surface reflects by reflection shield 4, and the weakness zone of additional direct projection light; It is the overlapping concentrated light of light under the lamp that the effect of light reflecting board 5 is divided at the center, is refracted to remote point, increases the brightness of far point, improves the average illuminating effect of light.Also be provided with glass light-passing board 6 in reflection shield 4 outsides, prevent the laying dust on led module 3 surfaces and influence illumination effect.
