LED optical-concentrated device in direct impact mode

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

technical field [0001] The invention relates to a light collecting device, in particular to a counter-type LED light collecting device. Background technique [0002] In the existing traditional LED light-collecting devices in the form of reflectors, the LEDs are arranged facing the front. Since the light-emitting characteristics of the LEDs are that the light intensity in the front is the highest, the more they deviate from the positive axis, the lower the light intensity. Usually At the position of the cone angle of 120°, the light intensity is only half of the light intensity value directly in front. At this time, the light intensity on the reflector is not the maximum value of the LED, and the strongest light does not pass through the traditional form of collection. The reflector of the light device can be reflected, but it is only scattered naturally. Therefore, the reflector of the traditional forward-facing LED does not make full use of the maximum light intensity of t...

[0002] In the existing traditional LED light-collecting devices in the form of reflectors, the LEDs are arranged facing the front. Since the light-emitting characteristics of the LEDs are that the light intensity in the front is the highest, the more they deviate from the positive axis, the lower the light intensity. Usually At the position of the cone angle of 120°, the light intensity is only half of the light intensity value directly in front. At this time, the light intensity on the reflector is not the maximum value of the LED, and the strongest light does not pass through the traditional form of collection. The reflector of the light device can be reflected, but it is only scattered naturally. Therefore, the reflector of the traditional forward-facing LED does not make full use of the maximum light intensity of the LED, and its reflection efficiency is naturally discounted. Not only does the reflector get twice the result with half the effort, but also Not enough reflective effect; and the maximum energy in the light source is wasted, and the ideal lighting effect cannot be achieved
