Light lamp assembly structure.

According to the characteristics of the light-emitting diode (LED), such as power saving, small size, long life, etc., the lights of existing vehicles such as steam and locomotives have used the light-emitting diode as the illumination source.

The existing lamp usually includes a light-emitting diode and a reflector cup, and the reflector cup is provided with a set of vertical components for the assembly and locking of the reflector cup, resulting in an increase in the manufacturing cost of the lamp and the assembly man-hour. Therefore, some manufacturers have neglected the setting of the reflector cup to save the manufacturing cost and the assembly procedure. However, since the light is scattered when the light emitting diode emits light, the light reflecting diode is omitted and the light emitting diode emits light directly. For the direct-type headlights emitted by the lens, please refer to the ninth figure. The near-light type is rectangular, the upper and lower widths of the light field are about 5.5 degrees, and the light intensity at the center is 8326 candelas [cd]. The effective luminous flux is 165 lumens [lm]. Please also refer to the tenth figure. The far-light type is rectangular and the upper part is slightly arcuate. The light field is distributed in the upper and lower widths of about 5 degrees. The intensity is 19,800 candelas [cd], and the effective luminous flux is 205 lumens [lm], so there is a problem that the light source range is small and the brightness is low. Therefore, some practitioners have studied to change the curvature of the lens mounted on the front of the light-emitting diode in order to improve the light projection efficiency of the light-emitting diode. The closer the position of the light-emitting diode to the lens is found by the experimental system, the light of the light-emitting diode is The higher the projection efficiency, the more the convex curvature of the lens must be convex, which causes problems such as bubbles in the lens injection molding, resulting in an increase in the defective rate, and the lens forming time must be relatively extended, resulting in a loss of manufacturing cost.
