The thickness of the upper half of the patch lens is between 4.5mm-5.5mm, e.g. 4.7mm, 4.9mm, 5mm, 5.1mm, 5.2mm, 5.3mm, 5.4mm, etc. The upper half of the patch lens has a diameter of between 7mm and 9mm, for example 7.5mm and 8.5mm, such as 7.3mm, 7.5mm, 7.8mm, 8mm, 8.2mm, 8.3mm, 8.5mm, 8.7mm, etc. The thickness of the lower half of the patch lens depends on the thickness of the LED light source. Which is nearly flush with the top surface of the LED light source as shown to better control the angle and intensity of the light beam from the LED light source and to avoid light loss as much as possible.

The light emitted by the point-shaped luminous body is refracted by the prism, so that a starlight effect which cannot be formed by the planar luminous body is generated, and the application coefficient effect of the lamp is improved. In the present embodiment, the number of LED light sources is 2, but any number of LED light sources may be used. If a single LED source is used, the power of the LED source may be 1W or more, and if a plurality of LED sources are used, a low power LED may be used, the power may be 0.2W-2W. The LED point-shaped outline lamp is powered by at least one constant current source through a power supply line (such as a circuit board positioned below the LEDs). In the present embodiment, a constant current source 14 for supplying power to the LED light source is used, and is connected to the LED light source for ensuring that the LED working current is constant. The patch lens 17 placed in front of the LED light source 13 makes the angle of light emission of the LED light source between 30 and 120 degrees.
