Abstract
The utility model discloses an energy-saving emitting diode. A conductive connecting base is arranged at the bottom of a package body, a control circuit is arranged inside the connecting base, a cavity is arranged on the package body, a luminous body is arranged at the bottom of the cavity, and the luminous body is connected with the control circuit inside the connecting base through a conducting wire; and the side wall of the cavity is an inclined plane which extends from bottom to top, the surface of the cavity is paraboloid-shaped after cutting through the longitudinal direction, a reflective surface is arranged on the surface of the cavity, and the luminous body is arranged at the focal point of the reflective surface. The diode is conducive to improving brightness.
Description
Technical field
The utility model relates to a kind of emitting components, is specifically related to a kind of energy-conservation emitting diode.
Background technology
Emitting components is widely used on the various luminous or display unit, and for example illuminating lamp, desk lamp, indicator light, advertisement show in the light guide plate of fluorescent tube and LCD.Emitting components generally includes cold cathode fluorescent lamp, fluorescent lamp, electroluminescent device and light-emitting diode, and wherein, IED has high efficiency, high brightness, high evenness, high response speed, low power consumption and other advantages and receives much concern.In fact, since LED comes out, the application surface of LED more and more widely, the advantage of its environmental protection and energy saving is regarded as one of main lighting source of 21 century.
Energy-conservation emitting diode is a kind of in the emitting components, in recent years, because energy-conservation emitting diode is evolved to slim product gradually, its cavity bottom minor face size is further limited, narrower, the light energy losses that causes the multiaspect of luminous element to penetrate is bigger, and brightness is restricted.
Summary of the invention
At above-mentioned technical problem, the purpose of this utility model provides a kind of energy-conservation emitting diode that improves brightness that is beneficial to.
The technical scheme that realizes the utility model purpose is as follows:
Energy-conservation emitting diode, the bottom surface of packaging body is provided with the Connection Block of conduction, be provided with control circuit in this Connection Block, packaging body is provided with cavity, and cavity bottom is provided with luminous element, and luminous element is connected with control circuit in the Connection Block by lead, the sidewall of cavity is the inclined-plane that extends toward the top from the bottom, the surface of cavity is parabolic shape after longitudinal part cuts, the surface of cavity is provided with reflective surface, and described luminous element is arranged at the focus place of reflective surface.
The top of cavity is provided with light penetrating object, and this light penetrating object is the light penetrating object of plastics.
Cave in to the light penetrating object lower surface in the middle part of the upper surface of described light penetrating object.
Adopted such scheme, the surface of cavity is parabolic shape after longitudinal part cuts, and the surface of cavity is provided with reflective surface, and described luminous element is arranged at the focus place of reflective surface.When luminous element was luminous, its light that sends after major part reflects by reflective surface, converged the light beam that forms a high brightness from the focus of reflective surface again, and this light beam is called main beam; The fraction light that sends from luminous element is low-angle to front irradiation, forms the more weak inferior light beam of light.Night, main beam can allow people be clear that the details of things at a distance when being used for throwing light on, and inferior light beam can be seen object profile clearly.Therefore,, not only can reduce the energy loss of diode, evolve to slim product gradually but also help energy-conservation emitting diode by after on the parabola that forms reflecting surface being set.
The middle part of the upper surface of described light penetrating object helps protecting light penetrating object like this to light penetrating object lower surface depression.
