Problems solved by technology
like Figure 7 As shown, it will cause insufficient brightness of the area lights beyond the 50-degree view point range
When lighting appliances with good display are required, and high-brightness displays, warning devices or information display boards are required, multiple light-emitting diodes must be densely arranged in a limited area to meet the required brightness requirements. Due to the unit There are many light-emitting diodes arranged in the area, in addition to greatly increasing the production cost, and the increase in the density of the light-emitting diodes will greatly increase the operating temperature of the device, thus shortening the service life of the light-emitting diodes and equipment

A LED is made up of the positive and negative pins and LED chip connected to the pins with a concave at the up end of the negative pin to be mounted with the LED, in which the up end of its positive pin is connected bya wire with a LED chip in the negative concave. The characteristic is to contains also can cylindrical plastic gel adhering the up end of the position and negative pin and the chip with a convex arc face at the top convex of the said column. The outside diameter of which is 8 mm, height is 4 mm, the arc radius of the convex arc is 5 mm, stonting angle is 38 deg and the ending angle is 142 deg.
Description
technical field [0001] The invention relates to a light-emitting diode, and in particular, the invention relates to a light-emitting diode with a multi-view function. The light-emitting diode can improve luminous efficiency and reduce the production cost of related products using the light-emitting diode. Background technique [0002] Currently, light emitting diodes (light emitting diodes, LEDs) are widely used in daily life applications. The principle of a general light-emitting diode is to apply a voltage between two electrode terminals connected to a light-emitting diode chip. The combination of electron and hole pairs in a diode wafer connected between two electrodes generates energy and converts it into light. Light-emitting diodes are widely used in various electrical instruments, information display screens and communication products. It has reached the level of being closely related to human life and inseparable. Therefore, how to use light-emitting diodes to ob...
