Description

Hedge type LED light collection device

technical field

The utility model relates to a light collecting device, in particular to a hedge type LED light collecting device.

Background technique

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 There is not sufficient reflection effect; and the maximum energy in the light source is wasted, and the ideal lighting effect cannot be achieved.

Utility model content

In order to solve the above problems, the purpose of this utility model is to provide a method that can make the effective light intensity of the LED in the light collecting device irradiate the reflective surface of the reflector in the most effective way, so as to make full use of the light intensity of the reflector. Hedge-type LED light collection device for the purpose of reflection and improving light efficiency.

The purpose of this utility model is achieved in the following way: a hedge-type LED light collecting device, including a shell 1, a lamp cover 2, the lamp cover 2 is clamped or sleeved on the upper opening of the shell 1, and the lower opening of the shell 1 is clamped Or socketed on the lamp body, a reflector 3 is clamped or socketed on the inner side of the lower opening of the shell 1, and a lens 4 is installed between the reflector 3 and the lamp cover 2; the bottom outside of the reflector 3 is fixedly connected to the circuit board 5 , the inside of reflector 3 is installed an LED7 by fixing frame 6, and the top direction of LED7 is opposite to the opening direction of reflector 3; In this way, the LED7 is facing the reflective surface of the reflector 3, and the effective angle light intensity emitted by the LED7 is emitted forward after being concentrated and reflected by the reflective surface. Effect.

The reflector 3 in the described hedge type LED light collection device is a parabolic reflector, and the LED7 is installed on the focus of the reflector 3, so that the light reflected by the reflective surface of the reflector 3 is emitted in parallel to increase the irradiation distance.

The reflector 3 in the described hedge type LED light collection device can also be a double parabolic reflector, LED7 is installed on the focus of the inner parabola in the middle of the reflector 3, and LED8 is installed on the focus of the outer parabola on the periphery of the reflector 3, In this way, when the two LEDs emit light, they can be reflected into parallel light by the reflector to enhance the brightness.

The lens 4 in the hedge-type LED light collecting device can be a plane lens or a convex lens, through which the light beam can be concentrated again to increase the irradiation distance.

The lens 4 in the described hedge-type LED light collecting device is bonded to the reflector 3 or the lamp cap 2, and can also be pressed against the reflector 3 by the lamp cap 2 to be fixed and stable.

The fixing frame 6 in the said hedge-type LED light collecting device can be replaced by the legs of the LED7, thereby simplifying the structure and saving resources.

The utility model aims at the characteristic that the maximum value of the LED light intensity is located directly in front of the axial direction, and installs an LED in reverse, directly facing the inner paraboloid in the middle of the reflector, and can make full use of the maximum light intensity within a limited angle to form a The light column with good reflection effect improves the light efficiency compared with the traditional reflective form; the light intensity emitted by the side of the LED at the back falls on the parabolic surface around the reflector, and forms another coaxial ring-shaped light column through the outer paraboloid. After the superimposition of the two light beams, the brightness of the spot can be enhanced, and at the same time, it can also play the role of a signal light and supplement the ambient light source outside the spot. At the same time, the circuit board can produce four states of two LEDs being bright at the same time, dark at the same time, and single bright through the conversion of the circuit, which can not only give full play to the effect of the light source, but also adapt to the needs of different light intensities and irradiation distances. Moreover, the hedge-type LED light-collecting device has a simple structure and is easy to maintain, so it can be widely used in various lamps, especially mobile and fixed lighting lamps such as flashlights.
