Abstract

The invention relates to an LED optical-concentrated device in direct impact mode, which comprises a shell, and a socket cover. The device has the characteristics that a reflector is clamped or sleeved on the inside of a lower opening of the shell; a circuit board is fixedly connected on the outside of the bottom of the reflector; an LED is arranged in the inner part of the reflector through a holder and the top direction of the LED is opposite to that of the opening of the reflector; and an LED is arranged in a direct impact mode on the inner bottom part of the reflector corresponding to the LED. The LED straightly faces a reflective panel of the reflector, an effective angle light intensity giving out by the LED shoots up forwardly through the spot light reflection of the reflective panel and an effective angle light intensity giving out by the other LED shoots up forwardly. Therefore, two light crosses overlay to enhance effects of facula, and can generate four states of simultaneously lighting, simultaneously dark, and single lighting of the two LEDs, which fully exerts the effects of light source and is applicable to the demands of different light intensity and lighting distance. The LED optical-concentrated device in direct impact mode is simple in structure, and convenient in maintenance, and can be widely used in various luminaries.

Description

Hedging type LED optical-collection device

Technical field

The present invention relates to a kind of light collecting device, particularly a kind of Hedging type LED optical-collection device.

Background technology

In the LED light collecting device that has traditional employing reflection shield form now, LED is the positive layout of face forward, because the characteristics of luminescence of LED is that the light intensity in dead ahead is the highest, more depart from the forward axis, its light intensity is just lower, usually in the position of 120 ° of cone angles, its light intensity just only have the dead ahead light intensity value half, the light intensity that shine on the reflection shield this moment has not been the maximum of LED, the strongest light is not reflected by the reflection shield of traditional form light collecting device, it is natural scattering, therefore its reflection shield of LED of conventional forward layout does not take full advantage of the largest light intensity of LED, its reflector efficiency has just been made a discount naturally, and reflection shield is got half the result with twice the effort, and does not have sufficient reflection action; And wasted the ceiling capacity in the light source, do not reach desirable illuminating effect.

Summary of the invention

In order to address the above problem, the objective of the invention is to take full advantage of the Hedging type LED optical-collection device that reflection shield carries out the light intensity reflection, improves the purpose of light efficiency for providing a kind of efficient intensity of the LED in the light collecting device that can make to shine on the reflective surface of reflection shield in the most effective mode thereby reach.

The object of the present invention is achieved like this: a kind of Hedging type LED optical-collection device, comprise shell 1, lamp cap cover 2, lamp cap cover 2 clampings or be socketed in the upper shed of shell 1, the under shed clamping of shell 1 or be socketed on the lamp body, in the inboard clamping of the under shed of shell 1 or be socketed a

reflection shield

3,2 of reflection shield 3 and lamp cap covers are equipped with a slice lens 4; The bottom outside of reflection shield 3 is fixedly connected with wiring board 5, and a LEDs 7 is installed by fixed mount 6 in the inside of reflection shield 3, and the opening direction of the top-direction of LED7 and reflection shield 3 is opposite; Inside, bottom and the LED7 opposite position of reflection shield 3 adopt opposite-flushing type that one LEDs 8 is installed.LED7 faces the reflective surface of reflection shield 3 like this, and the effective angle light intensity that LED7 sends penetrates by the rear forward of reflective surface optically focused reflection, and the effective angle light intensity forward that LED8 sends penetrates, the light beam stack that two LED produce, the effect of enhancing hot spot.

Reflection shield 3 in the described Hedging type LED optical-collection device is double-paraboloid line reflective mirror, LED7 is installed on the interior parabolical focus at reflection shield 3 middle parts, LED8 is installed on the outer parabolical focus of reflection shield 3 peripheries, such two LED all can be reflected into directional light by reflective mirror when luminous, highlight.

Lens 4 in the described Hedging type LED optical-collection device can adopt planar lens or convex lens, can again light beam be carried out optically focused by convex lens, increase irradiation distance.

Lens 4 in the described Hedging type LED optical-collection device are bonded on reflection shield 3 or the lamp cap cover 2, also can lean on lamp cap cover 2 to be pressed on reflection shield 3, fixing-stable.

Fixed mount 6 in the described Hedging type LED optical-collection device can LED7 leg replace, thereby simplified structure, saving resource.

The maximum that the present invention is directed to the LED light intensity is positioned at the characteristics in axial dead ahead, a LED is oppositely installed, directly face the interior parabola at reflection shield middle part, can take full advantage of the largest light intensity in its limited angle, form a good light beam of reflecting effect, more traditional reflective form light efficiency is improved; The light intensity that send the LED side of back drops on the parabola of reflection shield periphery, form another coaxial annular light beam by outer parabolic concentrator, after two light beam stacks, can strengthen the brightness of hot spot, the effect that can also play signal lamp simultaneously and replenish hot spot external environment light source.Simultaneously, circuit board can produce simultaneously bright, dark, single bright four kinds of states of while of two LED by the conversion of circuit, not only can give full play to the effect of light source, can also be suitable for the needs of different light intensity and irradiation distance.And this Hedging type LED optical-collection device is simple in structure, easy to maintenance, therefore can be widely used in the mobile and fixed lighting lamp such as various light fixtures, particularly flashlight.
