Embodiment Construction

[0012] Embodiment 1 of this multi-light path synthesis semiconductor light emitter is shown in Figures 1, 2, and 3. It includes a plurality of semiconductor light-emitting diodes, and the leads of the light-emitting diodes are insulated from the base. The main body of the light emitter is a housing 7 with a concave surface. , the concave curved surface of the housing 7 is a hemispherical surface, and it is a reflective mirror surface. Outside the center of the bottom of the concave curved surface of the housing 7 is the base 5 of the light emitter, and a plurality of light-emitting diodes 1 are mounted on the concave hemispherical surface of the housing 7 according to a conventional method. , evenly distributed on the circumference. The light emitting diodes 1 are connected in series or in parallel, and the bottom of the casing 7 has a lead hole 3 through which the positive and negative lead wires of the light emitting diodes 1 are led out. The radial strut 6 is fixed at the c...

Abstract

Main body of the illuminator is as body case of mean axis symmetrical concave curved face such as semi-sphere or paraboloid. Pasted on light-reflecting concave curved face, LEDs are connected in series or parallel, and wire is led out from bottom of the body case. Light-reflecting ball is installed on mean axis fixedly. Diameter of light reflecting ball is equal to 1 / 4 - 1 / 2 diameter of intersecting circle between the plane perpendicular to the mean axis and the concave curved face. Each LED is positioned behind the plane, which contacts the top of the light-reflecting ball, or is perpendicular to mean axis of concave curved face and passing through center of sphere of the ball. Lens closes down exit of the body case. Each LED emits light to light-reflecting ball, which reflects light to the exit, or to the concave curved face, and then to the exit. Power of the illuminator can be reach to 10-500 watt. Near panchromatic light can be composed from arranged LEDs in different colors.

Description

(1) Technical field [0001] The invention relates to a semiconductor electric light source, in particular to a multi-light path synthesis semiconductor light emitter. (2) Technical background [0002] Semiconductor light-emitting diodes have long working life, stable light emission, low energy consumption, and many colors, and are widely used as signal lights. However, the power of light-emitting diodes is small, and the largest light-emitting diodes in my country are only 3 to 5 watts. Due to the limited power of a single light-emitting diode, its luminous brightness is difficult to meet the requirements. In order to improve the brightness, the general display screen is to mount multiple light-emitting diodes on the plane to form numbers or patterns. However, this planar device for combining a plurality of light emitting diodes can only be used for display screens, and is not suitable for use as a lighting source. (3) Contents of the invention [0003] The purpose of th...
