Abstract
The utility model discloses an LED tube light with high luminous efficiency. The LED tube light comprises a light body outer shell, an aluminum reflector cup arranged in the light body outer shell, and an LED light-emitting module arranged at the bottom of the aluminum reflector cup. The LED tube light is characterized in that a milk white saucer-shaped light-transmitting cover covering the LED light-emitting module is arranged at the inner bottom of the aluminum reflector cup. Therefore, when the LED tube light is used for illumination, primary light emitted by the front of the LED light-emitting module directly forms a primary illumination beam even in luminescence and free of light spots and dark areas through a base plate of the milk white saucer-shaped light-transmitting cover to be projected to a working face to be illuminated, and secondary light emitted by side edges of the LED light-emitting module is uniformed and refracted through the side wall of the milk white saucer-shaped light-transmitting cover, then reflected and output through the aluminum reflector cup with high reflectance, and also projected to the working face to be illuminated; therefore, the light is evenly emitted and free of light spots and dark areas when a lampshade is seen from the front, efficiency of effective light output is more than 90%, illumination for the working face is high, and the luminous efficiency is high.
Description
Technical field
The utility model relates to field of light fittings, particularly a kind of LED Down lamp of high light efficiency.
Background technology
At present, the high-power LED light source has been widely used in various indoor and outdoor locations, and is particularly outstanding to be inlaid in the lightings such as the LED Down lamp that light shone get off, LED Grille lamp.The LED Down lamp of existing market generally by the lamp body shell, the printing opacity face shield etc. that is installed on aluminum aluminium reflector in the lamp body shell, is installed on the LED illuminating module of aluminium reflector bottom and is positioned at aluminium reflector outside forms, wherein the printing opacity face shield adopts the milky lampshade on plane mostly, owing to worrying to produce high some hot spot after bright light on the acrylic of plane, the distance of LED illuminating module and milky lampshade generally surpasses 3CM, make like this distance of part lamp pearl and lampshade far, be unfavorable for that light penetrates.Simultaneously the plane acrylic can make the part light that LED sends more easily be reflected back die cavity in lamp body, makes the general light output efficiency of light fixture of this lamp type less than 60%, and light refraction out after also many in the space of loss, so illumination of working plane is low, as shown in Figure 3.Another kind of structure is as the disclosed Down lamp of Chinese patent that the patent No. is ZL201120042842.5, employing is provided with and the circular diffuser of the bullet cut of LED illuminating module coupling in the inside center of aluminium reflector, and done the frosted processing at the inwall of circular diffuser, to improve the diffusion rate of light, as shown in Figure 4, the problems such as what but it was same exists light output efficiency less than 58%, and fiber-loss is many, and illumination of working plane is low.
Summary of the invention
The purpose of this utility model is for above-mentioned existing problems and deficiency, provides a kind of front to watch lampshade luminous evenly, and without hot spot and dark space, and light output efficiency surpasses 90%, the real energy-conservation high light efficiency LED Down lamp of the high and low energy consumption of illumination of working plane.
The technical solution of the utility model is achieved in that
High light efficiency LED Down lamp described in the utility model, comprise the lamp body shell, be positioned at the aluminium reflector of described lamp body shell and be installed on the LED illuminating module of described aluminium reflector bottom, be characterized in that the inner bottom part of described aluminium reflector is provided with the milky dish shape diffuser of housing on described LED illuminating module.
Wherein above-mentioned dish shape diffuser comprises the concave shaped cover body and is shaped in the locating ring limit at this cover body upper port place, this dish shape diffuser by its locating ring limit with being connected of aluminium reflector bottom position of above-mentioned LED illuminating module periphery reliably housing on the LED illuminating module.And its preferred version is that the base plate of above-mentioned concave shaped cover body is that arc transition is connected with the junction of its sidewall.The diameter of the base plate of above-mentioned concave shaped cover body will be a bit larger tham or equal the diameter of above-mentioned illuminating module.
For making the utility model can guarantee on the one hand optimal luminescent distance between LED illuminating module and diffuser bottom surface, the light penetration rate is high, can guarantee again that on the other hand light enters the slightly higher angle that vertically enters of milky diffuser, to reduce to greatest extent the light that is reflected back the diffuser inner chamber, the height between the illuminator in above-mentioned LED illuminating module and the base plate of above-mentioned diffuser is 25-30mm.
For further improving the diffuse effect of the utility model emitted light, so that light is softer evenly, the interior reflective surface of above-mentioned aluminium reflector is the arc mirror surface structure with some scale shape reflective structures of sequentially arranging.
The utility model is owing to adopting the structure of establishing again the milky dish shape diffuser of a housing on described LED illuminating module at the inner bottom part of aluminium reflector, make the utility model in the process of illumination, the main light that sends because of LED illuminating module the place ahead is directly by seeing through the base plate place of milky dish shape diffuser, and forming does not luminously evenly have again the main illumination beam of bright spot, hot spot and dark space to project the working face that light fixture will shine; The less important light that its side sends is after first passing through all light and refraction of milky dish shape diffuser sidewall, export through the aluminium reflector reflection of high reflectance again, also project the working face that light fixture will shine, so not only the front watches lampshade luminous evenly, without hot spot and dark space, and effective delivery efficiency of light can surpass 90%, illumination of working plane is high, really accomplished low energy consumption, effectively solved existing LED Down lamp fiber-loss many, the problem such as illumination of working plane is low.Product of the present utility model has obvious high output, low energy consumption characteristics, is the LED illuminating product of a real efficient energy-saving, can be widely used in the places such as market, office.
Below in conjunction with accompanying drawing, the utility model is further described.
