technical field

Background technique

Since the power consumption of light-emitting diodes (LEDs) is far less than that of traditional filament bulbs, people have always been thinking about replacing filament bulbs for lighting and promoting environmental protection and energy saving. Ability, but the light-emitting diode as small as a bean, the brightness is too concentrated in the center of the point; the light is scattered in all directions, and cannot be directed to the front to illuminate the target. The lack of scattered beam illumination with a certain limited beam range still needs to rely on spotlight The photomask controls the amount of light and guides it to spread out in an appropriate range forward, so as to obtain sufficient light amount and light field illumination for the target object.

However, the spotlight shades currently applied to LEDs are mostly in the shape of traditional light-transmitting mirrors, which are adjusted to correspond to the size of LEDs. Although they also have the effect of scattering LED light for lighting, they are not aimed at the self-illuminating body structure of LEDs. However, the light-emitting range of the LED is still not concentrated enough, and the astigmatism emitted to the side still does not go through the condensing mask to concentrate the light on the target, which causes the brightness loss of the illuminated area for no reason. In order to achieve sufficient lighting, LEDs with higher power consumption must be used to increase the brightness of the lighting, but there is still the problem of improper power consumption.

The main shortcomings of the general light-emitting diode structure are as follows: First, because the light-emitting diode is a simple light source, its light is scattered in a radial manner; and the general light-emitting diode itself cannot gather light, so that the light diffusion is not concentrated and the brightness is reduced. .
