LED cup light concentrating structure

The present invention relates to an LED cup lamp structure, in particular to a concentrating structure of an LED cup lamp, to improve the illuminating structure of the illumination angle of the LED light source.

In today's illuminating devices, LEDs have been commonly used as illuminating elements, but different functions are required depending on the user. Among various types of light-emitting devices, the spotlight has a good light source concentration effect, and therefore, it is commonly used in, for example, a stage drama, a photographer's work, an indoor decoration, and the like, and an illumination light-emitting lamp that requires a cup light collecting function.

As shown, the conventional cup lamp structure has a lamp base 1 having a top end 11 and an inner ring surface 12, the inner ring surface 12 being coated with a reflective layer. The top end 11 of the cup base 1 is joined to a cup 2 which projects a pair of pins 21, wherein the conventional cup illumination uses a halogen lamp.

The electric power is transmitted from the pin 21 of the cup holder 2 to the halogen lamp via the electric wire. The halogen lamp projects a light source, and the light source makes the light source more bright by the light reflecting layer, but the range of the light source is irradiated by the cup lamp. The size of the opening of the inner annulus 12 of the base body 1 is limited.

Therefore, how to solve the conventional problems and improve the concentrating structure of the LED cup lamp is a subject that is pursued by those involved in this industry.

In view of the above conventional problems, the main purpose of the present invention is to concentrate the light structure of the LED cup lamp to provide a concentrating structure which effectively improves the angle of illumination of the light source and the light source.

In order to achieve the above object, the concentrating structure of the LED cup lamp of the present invention is embedded with an inner ring cover in the inner space of a cup of the lamp base. The inner ring cover has an inner ring reflecting surface, a top edge and a bottom edge, and the bottom edge is defined as a light source projection end, and a reflective layer is formed on the inner ring reflecting surface of the inner ring cover. The top edge of the inner ring cover fits the LED light source module, and the LED light source module includes at least one LED light emitting element.

The lamp base system is selected from one of metal and heat-dissipating plastic.

The cup holder protrudes from the pair of pins, and the pins are respectively connected to the LED light source module via a wire.

Wherein the bottom edge of the inner ring cover is further provided with one of a planar lens, a convex lens and a concave lens.

One of a planar lens, a convex lens, and a concave lens is disposed adjacent to the LED light source module in the inner ring cover.

In terms of effects, since the inner ring cover in the present invention has an inner ring reflecting surface, the inner ring reflecting surface is formed with a reflective layer, and the light source generated by the LED light emitting element is projected by the light source projection end of the inner ring cover. a light source through which the light source can achieve a concentrating effect.
