A light distributing board is installed in a groove in the middle position of the shell, and the light emitted from the light distributing board is used for increasing the brightness in the middle of a lampshade; the radiator is a combined body of radiating plates and a fan, and the fan is fixedly connected with the radiating plates. The device for increasing light emission efficiency and light distribution uniformity of the LED lamp is simply structured, fastened, convenient and practical, prolongs the service life of the LED, and increases the illumination effect.
Description
Technical field
The utility model relates to a kind of device of LED light fixture, relates in particular to a kind of raising LED lamp luminescence efficient and luminous intensity distribution and installs uniformly.
Background technology
Semiconductor light-emitting-diode (being called for short LED) is that a kind of energy-saving and environmental protection, color are pure, the solid light source of overlong service life; scientific circles, engineering bound pair LED Study on Technology are very active always in recent ten years, and light sources such as the incandescent lamp that uses led light source to replace generally to use at present, fluorescent lamp, electricity-saving lamp are started to walk.Each country of the world and company all drop into the luminous efficiency that great amount of manpower and material resources research improves semiconductor light-emitting-diode, development of new chip design technology, packaging technology material technology, source material technology, light fixture material technology etc.Because light emitting diode itself is very sensitive to heat, himself temperature to luminous efficiency, life-span, make creating a great impression of encapsulating material sex change.The heat dispersion of light emitting diode has very important influence to luminous efficiency, bad if dispel the heat, can cause the temperature of pn knot too high, cause luminous efficiency to descend, LED self life-span reduces, the material that surrounds led chip is formed fire damage, and this will make the LED luminous efficiency significantly reduce again, and it is the key in LED luminous efficiency and life-span that the led chip heat in time sheds.
The utility model content
The utility model will address the above problem to be provided a kind of light source high efficiency and by the luminous intensity distribution plate light source luminescent is installed uniformly.
For addressing the above problem, the utility model is realized by following scheme: comprise shell, described light source board is installed on the shell inner platform, is fastenedly connected with screw and shell; Radiator is installed in the outer groove of shell, is fastenedly connected with screw and shell, becomes monolithic construction; The luminous intensity distribution plate is installed in the groove in centre position in the enclosure.
Described shell is a highly heat-conductive material.
Described radiator is the combination of fin and fan, and fan is fixedlyed connected with radiator.
Described light source board, radiator and shell bond together with colloid.
The utility model one is the luminous heat dissipation problem of LED, and the heat that the LED lamp is produced looses fast in extraneous air, improves the led light source luminous efficiency; The 2nd, the problem that the annular LED light source center is dark partially, blackening in the middle of the luminous intensity distribution plate can be eliminated, make the LED annular light source can be luminous uniformly, guarantee that it is to improve the design focal point of LED lamp luminescence efficient that described LED has good performance of heat dissipation, because all on illuminator or electronic controller power device, the heat of conventional light source light fixture can not be directly transferred on the lamp outer casing conventional light source heat.The heat of led chip can be directly transferred on the metal substrate, and metal substrate is transmitted on the fin of encapsulating structure by copper material again.The present technique core is exactly that the heat on the LED package cooling sheet is directly transferred on the shell of metal material, and the shell fin of metal material can module superpose, the heat that led chip is produced that can be quantitative is transmitted on the shell of light fixture timely, make the temperature of pn knot remain on lower level, thereby improve the luminous efficiency of led light source significantly.
The characteristics directive property of described led light source is more intense, the uniformity of area source is wanted very again when design LED light fixture, the light that sends along with the increase of ring diameter in the annular LED light source board is mapped to the middle blackening phenomenon of appearance on the lampshade, by the luminous intensity distribution plate being installed at shell, the light that sends with the luminous intensity distribution plate increases the middle brightness of lampshade, make LED and the brightness unanimity of light source, its illuminating effect is better.
Improve LED lamp luminescence efficient and the uniform device solves of luminous intensity distribution the heat that produces of LED lamp loose in extraneous air fast, improve the led light source luminous efficiency, blackening in the middle of the luminous intensity distribution plate can be eliminated, make the LED annular light source can be luminous uniformly, and it is simple in structure fastening, convenient and practical, prolong LED service life and increase illuminating effect.
Description of drawings
Fig. 1 is a main structure schematic diagram of the present utility model,
Fig. 2 is the vertical view of the utility model radiator,
Fig. 3 is the schematic diagram of the utility model radiator.
The specific embodiment
The described main structure of Fig. 1, light source board 2 are installed on shell 1 inner platform, are fastenedly connected with screw and shell; Radiator 3 is installed in the shell 1 outer groove, is fastenedly connected with screw and shell 1, becomes monolithic construction; Luminous intensity distribution plate 4 is installed in the groove in centre position in the shell 1; Light source board 2, when being connected with shell 1, radiator 3 is coated in the surface of contact-making surface earlier with the heat conduction colloid, the heat of light source board 2 is better loose on shell 1 and radiator 3, the LED luminescence chip is delivered to case surface by a series of metal heat-conducting, and 4 effects of luminous intensity distribution plate are to eliminate the middle blackening phenomenon of lampshade.
Fig. 2,3 described, radiator 3 is combinations of fin and fan, and fan is fixedlyed connected with fin, and the fan power supply line connects by the shell power hole and drives, and starts fan when light-source temperature is high, and rotation speed of the fan is relevant with light-source temperature; Radiator 3 shapes and light fixture appearance similar, how many radiators 3 can decide its thickness by the heat that light source produces.
