Light fixture with light guide ring

The present invention relates to a kind of lamp, in particular to a lamp which can increase the light-emitting angle and range effect of the light-emitting diode module by using the light-guiding ring body.

According to the current, there is a light bulb using a light-emitting diode (LED) as a light source. The power supply type of a general incandescent light bulb can be directly installed in a conventional light bulb holder; however, the light-emitting diode bulb similar to the conventional one is lit. At the same time, the light-emitting diode light source as the light source belongs to direct light, and the light source generated by the entire light-emitting diode bulb can only illuminate toward the area directly facing the light-emitting diode, and fails to face the light-emitting diode. The peripheral area on the side produces a lighting effect. For example, as shown in FIG. 1A and FIG. 1B, the lampshade used in the conventional LED light source device 10' is mostly arc-shaped and is mounted on the wall surface 20' to achieve illumination and visual beauty; however, When the LED light source device 10' is screwed to the socket 21' of the corresponding wall surface 20', the LED chip 11' is in a parallel state with the wall surface 20'. As shown in FIG. 1B, since the innate light source characteristic of the LED light source device 10' is direct light and the illumination angle thereof is small, the light source emitted by the LED chips 11' in the LED light source device 10' is directly directed toward the front (ie, the foregoing light source). The relationship of the horizontal direction illumination causes the wall surface 20' method to obtain the light source emitted by the LED chips 11'. Therefore, the wall surface 20' cannot effectively obtain the preset light source, resulting in poor overall illumination efficiency, thereby causing the LED light source. The illumination angle and range of the device 10' are limited, and even if the power of the LED is increased or the number of LEDs is increased, the LED light source cannot be solved. The device 10' has an insufficient illumination angle.

In addition, in order to increase the illumination angle of the light source, as shown in FIG. 2, a conventional bulb-type LED light source device 30' appears on the market, and the lampshade 31' used is in the form of a bulb, but the production cost and material cost of the injection molding are expensive. , does not meet the economic effects.

The outer diameter of the power base 14 is gradually reduced in a circular diameter toward the lamp cover 15 , and the outer side of the power base 14 is surrounded by a plurality of spaced fins (not labeled). ). The light guide ring 15 is integrally formed with a light guiding ring body 16 near the periphery of the power base 14; wherein the light guiding ring body 16 includes an outer ring surface 161 and an inner ring surface 162, and the outer ring surface 161 has at least one light emitting surface 161a. The annulus 162 has at least one light incident surface 162a. Since the outer diameter of the outer ring surface 161 is retracted toward the power base 14 (FIG. 4A to FIG. 4D), the light guiding ring body 16 can make the light emitted by the LED module 11 incident, and after refracting an angle, The rear side 15b' of the lampshade 15 is emitted. In other words, the lamp 1 having the light guiding ring body can be made, and the light emitted by the LED module 11 has a relatively full light emitting range and a high luminous efficiency due to the refraction phenomenon.
