Problems solved by technology

At present, the optical path, circuit, and thermal path of high-power LED light-emitting diodes must be arranged reasonably. If the light-emitting device is produced by using its concept packaging, it will inevitably bring heat that cannot be dissipated. The light is blocked in the resin, and the pins block the light. cost

Embodiment Construction

[0023] Image 6 It is the cross-sectional structure diagram of the embodiment of the LED reflection and condensing component. Let the LED (7) be embedded in the reflection cup (2), and the light is projected laterally on the curved surface of the reflection cup (18) to minimize the reflected light to the pin. Feet (3) to dissipate heat. It is said that the reflector cup (2) is formed by metal die-casting or plastic. The light exit opening (5) is the exit for reflecting parallel light (1), and the bottom opening (6) of the reflector cup is used to fix the foot (3) and lead out the electrode wire. , The reflecting cup is not filled with resin, the aluminum film is vapor-deposited on the inner curved surface of the reflecting cup (2) to form a reflecting curved mirror, and the side of the LED backlight is a cut surface (13). Here, LED (7) refers to high-power W-class LED, the heat sink copper insert should be welded on the copper base, the base (3) is fixed on the reflector (2), a...

Abstract

The invention relates to an LED (light-emitting diode) reflective condensing part which can converge the light rays of a light source at the approximate point of an LED into parallel light, and belongs to the application filed of LEDs. According to the LED reflective condensing part, the problems of shading, light blocking and radiating of the existing reflective LED are overcome, the manufacturing cost is reduced, and parallel light emitting can be realized. The LED is embedded into a reflective cup, the light rays are sidewise projected to the curved surface of the reflective cup so that pin shielding of the reflective light is least, and a pin base is arranged at the other side so that heat energy can be lead out for heat dissipation. The central line of the LED light forms an included angle (about 50 degrees) with the symmetrical axis of the curved surface of the reflective cup, the light rays of the LED are projected to the curved surface of the reflective cup, and the reflective light rays are parallelly emitted. The curved surface of the reflective cup is changed to be paraboloid, hyperboloid and elliptic surface, so that parallel light, defocusing light and focusing light can be emitted. The parts provided by the invention can be applied to flashlights, searchlights, headlamps, projection light sources and the like.

Description

Technical field [0001] The invention relates to an LED light converging and projecting technology, which can converge the light of the LED similar to a point light source into parallel light through a reflecting cup. This technology belongs to the field of LED applications. Background technique [0002] At present, in the field of light projection, parallel light has a wide range of applications in various occasions due to its unique advantages. Generally, LEDs are converged by lens refraction. This method is limited by the containment angle (about 40 degrees) and it is difficult to increase the convergence rate. Only the reflective type can contain the LED light to the maximum and achieve a high concentration rate. One type of DR-LED condenses light through lens refraction and reflection mirror convergence. Due to its complex optical path and many interference factors, it is difficult to implement. Patent 200420097538.0 LED total reflection parallel light emitting device. T...
