Abstract
The utility model discloses a light-emitting diode (LED) light source which comprises a substrate, a plurality of lamp beads fixed on the substrate, and power lines which are connected with the lamp beads and used for energization. A lens is mounted in front of the lamp beads, and a plurality of convex mirrors corresponding to the lamp beads are arranged on the lens. By adoption of the structure, the properties such as light-admitting quality and uniform refractive index of the LED light source are improved substantially, and the dazzling phenomenon is greatly reduced. The LED light source enables light rays to deflect to diffuse directly through the convex mirrors on the lens so as to reach a higher illumination value, and is simple in structure and quite convenient to manufacture and maintain.
Description
Technical field
The utility model relates to the light source that a kind of LED makes.
Background technology
China's city illumination has the street lamp more than 2,000 ten thousand, along with in recent years growth rate more than 20%, the LED street lamp will become the trend of urban development, the advantages such as its luminous efficiency is high, stability is high, energy-conservation, environmental protection, life-span length, consumed energy reduces 75% with the incandescent lamp of light efficiency, well embodies the theory of environment protecting and power-saving.
Existing lighting such as street lamp, Tunnel Lamp, Projecting Lamp, floodlight or wall lamp etc., what generally adopt is the structure that reflector adds face shield.Because light source shines the brightness on ground and is inversely proportional to distance and irradiated area, distance loss far away is larger.Behind the led light source irradiation certain distance of existing structure, brightness is low and inhomogeneous, also produces yellow milky spot phenomenon.
The utility model content
For the technical problem of above-mentioned existence, the utility model provides a kind of led light source module, has higher brightness with respect to the led light source of traditional structure, and more even.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of led light source comprises substrate, is fixed on some lamp pearls on the substrate, is connected the power line that is used for energising with the lamp pearl.Described lamp pearl the place ahead is equipped with lens; Be provided with the some convex lens corresponding with the lamp pearl on the described lens.
Led light source with said structure, not only its light transmission, refractive index be even etc., and performance increases considerably, and also greatly reduces glare phenomenon.Convex lens on the direct scioptics of light source makes light generation deviation form diffusion, makes it reach higher brightness value, and is simple in structure, and the manufacturing maintenance is very convenient.
As a kind of preferred, add the squamous radiator behind the described substrate.Be convenient to the led light source heat radiation.
Further improve as above-mentioned improvement, the height of the fin of described squamous radiator increases progressively to the centre from both sides.Such arrangement mode radiating effect is best.
Further improve as above-mentioned improved another kind, add the graphite flake of heat conduction between described squamous radiator and the substrate.So more be beneficial to heat transmission.
Further improve as above-mentioned improved another kind, on the described squamous radiator respirator is installed.Be used for the inside and outside air pressure of balance led light source, prevent from producing in the light source negative pressure.After producing negative pressure, gas and water and dust inspiration light source that can light source is outer.
As a kind of preferred, described convex lens is half long ball shape.Its refractive index is better.
As a kind of preferred, described lamp pearl is 21, is 3 rows, 7 row and arranges; The corresponding arrangement with the lamp pearl of described convex lens.In order to increase the intensity of light source.
Improve as another kind, described lens and substrate outer rim are enclosed with waterproof apron.Anti-sealing and dust enter light source inside.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is explosive decomposition schematic diagram of the present utility model.
Mark among the figure: 1 lens, 1a convex lens, 2 squamous radiators, 2a fin, 3 power lines, 4 substrates, 5 graphite flakes, 6 respirators, 7 water proof rings, 8 lamp pearls.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
As shown in Figure 1:
The utility model comprises substrate 4, be fixed on some lamp pearls 8 on the substrate 4, be connected the power line 3 that is used for energising with lamp pearl 8.Described lamp pearl 8 the place aheads are equipped with lens 1; Be provided with the some convex lens 1as corresponding with lamp pearl 8 on the described lens 1.Add squamous radiator 2 behind the substrate 4, the height of the fin 2a of squamous radiator 2 increases progressively to the centre from both sides.Can add the graphite flake 5 of heat conduction between squamous radiator 2 and the substrate 4.On the squamous radiator 2 respirator 6 can also be installed.Convex lens 1a is preferably half long ball shape, and lamp pearl 8 can be 21, is 3 rows, 7 row and arranges, and convex lens 1a wants corresponding arrangement with lamp pearl 8.Lens 1 and substrate 4 outer rims can also be enclosed with waterproof apron.
For each lamp pearl 8 a convex lens 1a is set separately at lens 1, more even so that the brightness of whole light source is brighter in order to refraction with disperse the light of lamp pearl 8, also be not easy to produce yellow milky spot phenomenon.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
