Description
Technical field
The utility model relates to light fixture, particularly a kind of LED down.
Background technology
LED is writing a Chinese character in simplified form of English lightemittingdiode (light emitting diode); its basic structure is that one piece of electroluminescent chip of semiconductor material is cured on support; then chip and circuit board is connected; and use epoxy sealing surrounding; play the effect of protect IC, last mounting casing.LED have use low-tension supply, power consumption less, applicability is strong, stability is high, the response time is short, environmentally safe, the advantage such as multicolor luminous and be used widely.But simultaneously; due to the impact of the LED light source characteristics of luminescence; its irradiance is on the low side, uniform illumination degree is inadequate; when embody rule becomes LED lamp; lampshade must be used to carry out secondary light-distribution; but on existing market, most only emphasis of LED lamp cover used as secondary light-distribution protects light source, and not on the low side to LED light source irradiance and uniform illumination degree carries out corresponding Curve guide impeller.
Utility model content
The purpose of this utility model is to provide a kind of LED down, to solve the problem.
According to an aspect of the present utility model, provide a kind of LED down, comprise cover body, transparent panel, LED light source component and cover cap, transparent panel side is fixed with LED light source component, transparent panel opposite side contacts with cover body, and cover cap and cover body cover the LED down that rear formation order is followed successively by cover cap, LED light source component, transparent panel and cover body.LED light source component is fixed with LED light source, and the heat that LED light source luminescence produces passes to transparent panel by LED light source component with fixedly contacting of transparent panel, and transparent panel passes to cover body again and dispels the heat; And this LED down, LED light source component is between transparent panel and cover cap, and the light that LED light source sends shines directly on cover cap, then reflexes on transparent panel, goes out through transparent panel transmission.Thus, this LED down light path is simple, avoiding the loss that the multiple light path time produced by absorbing, making light source have better irradiance, also ensure that uniform illumination degree.
In some embodiments, cover cap is hemispherical cover cap, and is provided with light collecting part at cover cap inner top, and cover cap inside is also provided with light-reflecting portion, and light collecting part is positioned at the centre of light-reflecting portion.The illumination that the LED light source at each position sends is mapped to the light-reflecting portion of cover cap, and light converges to light collecting part after light-reflecting portion reflection, and light collecting part forms hot spot, and hot spot is gone out by transparent panel transmission.Thus, LED light path is simple, avoids light loss, and through the convergence of light collecting part, make uniform illumination degree better, brightness is stronger.
In some embodiments, transparent panel is transparent circular glass plate.Thus, transparency glass plate can be made stronger to the transmittance of light, and strengthen thermal diffusivity.
In some embodiments, have the cage apertures matched with transparent panel in the middle of cover body, the diameter of cage apertures is less than transparent panel, and cover body also comprises cover hurdle, and cover hurdle internal diameter and transparent panel diameter match, and cover marge footpath and cover cap match and can cover.Thus, transparent panel can be fixed on cage apertures, between cover hurdle and cover cap, and after cover cap and cover hurdle cover, play the effect protecting whole LED.
In some embodiments, cover body is the cover body of plastic material, and cover cap is the cover cap of plastic material.Thus, the cost of LED down can be saved, and make profile more attractive in appearance.
Accompanying drawing explanation
Fig. 1 is the structural representation of the LED down of a kind of embodiment of the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 show schematically show the LED down according to a kind of embodiment of the present utility model.As shown in the figure, this device comprises cover body 1, transparent panel 2, LED light source component 3 and cover cap 4, transparent panel 2 side is fixed with LED light source component 3, transparent panel 2 opposite side contacts with cover body 1, and cover cap 4 and cover body 1 cover the LED down that rear formation order is followed successively by cover cap 4, LED light source component 3, transparent panel 2 and cover body 1.LED light source component 3 is fixed with LED light source, and the heat that LED light source luminescence produces passes to transparent panel 2 by LED light source component 3 with fixedly contacting of transparent panel 2, and transparent panel 2 passes to cover body 1 again and dispels the heat; And this LED down, LED light source component 3 is between transparent panel 2 and cover cap 4, and the light that LED light source sends shines directly on cover cap 4, then reflexes on transparent panel 2, goes out through transparent panel 2 transmission.
Wherein, cover cap 4 is hemispherical cover cap, and is provided with light collecting part 41 at cover cap 4 inner top, and cover cap 4 inside is also provided with light-reflecting portion 42, and light collecting part 41 is positioned at the centre of light-reflecting portion 42.The illumination that the LED light source at each position sends is mapped to the light-reflecting portion 42 of cover cap 4, and light converges to light collecting part 41 after light-reflecting portion 42 reflects, and light collecting part 41 forms hot spot, and hot spot is gone out by transparent panel 2 transmission.
Wherein, transparent panel 2 is transparent circular glass plate, has the cage apertures 11 matched with transparent panel 2 in the middle of cover body 1, the diameter of cage apertures 11 is less than transparent panel 2, cover body 1 also comprises cover hurdle 12, and cover hurdle 12 internal diameter and transparent panel 2 diameter match, and cover hurdle 12 external diameter and cover cap 4 match and can cover.
In the present embodiment, cover body 1 is the cover body of plastic material, and cover cap 4 is the cover cap of plastic material.
LED light source is installed in LED light source component 3, when LED light source sends light, the heat produced can realize dispelling the heat by distributing or pass to the cover hurdle 12 on the cover body 1 and cover body 1 that contact with it with the transparent panel 2 that LED light source component 3 is fixedly connected with, and plays the object protecting light source; Meanwhile, light shines directly in the light-reflecting portion 42 of cover cap 4, through light-reflecting portion 42 reflect after converge to light collecting part 41, light collecting part 41 place formed hot spot, hot spot is gone out through transparent panel 2 transmission, light source irradiation degree and intensity of illumination better; Have the cage apertures 11 matched with transparent panel 2 in the middle of cover body 1, the diameter of cage apertures 11 is less than transparent panel 2, and cover body 1 also comprises cover hurdle 12, and cover hurdle 12 internal diameter and transparent panel 2 diameter match, and cover hurdle 12 external diameter and cover cap 4 match and can cover; Cover body 1, cover cap 4 are made by plastic material.Adopt the lampshade that this designs, light path is simple, and light loss is little; Through light collecting part 41 converge after uniform illumination degree and light source irradiation degree better; Cover cap 4, transparent panel 2 and cover body 1 can cover the effect playing protection LED light source completely by the mating reaction on cover hurdle 12; The cover body 1 of plastic material and cover cap 4 good looking appearance, production cost are lower.
Above-described is only embodiments more of the present utility model.For the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
