Description

Light source conversion system

technical field

The present invention provides a light source conversion system, especially a light source that can form a large area of traditional lamps to produce lamps with the same effect as LED lamps or at least a small illuminant, such as the existing Lightguide lamps.

Background technique

Light has been widely used in various fields and technologies, and in order to improve luminous efficiency and reduce energy consumption, LED (Light-Emitting Diode, light-emitting diode) has been developed to widely replace traditional lighting components. However, the cost of LED is high, its price is much higher than that of traditional light bulbs, and the conversion efficiency of electric energy of LED is only 15 to 20% into light energy, while 80 to 85% is converted into heat energy , LED temperature rise will lead to the decline of its luminous efficacy, and the degradation of yellow light is the most significant. Therefore, LEDs often need to install heat sinks to maintain luminous efficacy, which makes the cost of LEDs even higher.

Therefore, there is currently provided a "bulb-type car light with LED vision" such as China Taiwan Certificate No. M307544, which discloses a light bulb-type car light with LED vision, which includes: a lamp holder; a light bulb, which is installed on the lamp holder; the lamp frame is covered on the light bulb and assembled on the lamp holder, and has a plurality of perforations; the lamp shell is arranged on the lamp holder; The light body, the light-transmitting body is a transparent material and is spherical; the light generated by the bulb is reflected by the refracting surface on the inner edge of the lamp holder, and then projected from the light-transmitting body assembled in the perforation of the lamp frame, because the light around the lamp frame There is a tapered wall, so that the light is projected on the tapered wall and then refracted, so that it has the effect of concentrating light, so that the light bulb can also have the visual effect of LED illumination; however, the light bulb with LED vision In the case of a car lamp, the effective light area is only the perforation of the lamp frame, which means that the light needs to be reflected or directly irradiated to the perforation before the light can be projected from the light-transmitting body. It is worth noting that the lamp The frame is recessed toward the light bulb to form a tapered wall, and the tapered wall is only at one end of the light-transmitting part of the light-transmitting body, so that the light emitted by the light-transmitting body can be concentrated and projected, and the tapered wall At the other end, the light will be blocked by the concave cone-shaped wall, thus affecting the light output performance; in addition, it is difficult to achieve good brightness and projection distance only by the light-gathering effect of the light-transmitting body, so it still cannot achieve As LED vision, brightness and projection distance.

There is another kind of "car lamp device that can imitate multi-spots" such as China Taiwan Certificate No. M298539, which discloses a car lamp device that can imitate multi-spots, including: a lamp holder with a concave The base body, and a reflective coating on the inner surface of the base; a light bulb, located at the bottom of the base body of the lamp base; and a light-transmitting lampshade unit, with The lampshade on the base body, and a light-imitating point plate between the lampshade and the light bulb, the light-imitating point plate has a plate body, and a plurality of plates are formed on the plate body at intervals and face the direction of the light bulb A concave concave cup body, and a plurality of concentrating pillars protruding from the inner surface and bottom of the plurality of concave cups toward the lampshade, the light of the light bulb can be concentrated on the concentrating pillars above, make each condensing column form a light point; thus, as shown in Figure 5 of the car light device that can imitate multiple light spots, the light generated by the bulb can be projected by the concave cup or the condensing column out, so as to achieve the luminous effect of imitating the light-emitting LED, and the concave cup body has a cup bottom adjacent to the light bulb, and a cup peripheral part connecting the cup bottom peripheral edge and the plate body, and the cup bottom part The thickness is greater than the thickness of the peripheral part of the cup, so that more light emitted by the light bulb will be gathered on each light beam; Part of the light is directly emitted from the concave cup body, so it still cannot effectively achieve the vision, brightness and projection distance of LED.

There is also a "car light structure" such as China Taiwan Certificate No. M281838, which is to set up a reflector in front of the lamp housing. The front end of the reflector is provided with a number of reflecting surfaces that can reflect light A light bulb is assembled on the front side of the reflector, and a liner is set in front of the reflector, and a light-transmitting cover is arranged in the center of the liner, and a number of recesses are formed around the light-transmitting cover from the front side to the rear. , and at the rear end, there are reflective grooves with through-holes. At the same time, the orientations of each reflective groove are corresponding to the reflective surfaces of the reflective cover, and the end faces of the reflective grooves are provided with a plurality of light-reflecting grooves. On the reflective surface, in addition, a light-transmitting plate is set in the aforementioned perforation, and finally a light-transmitting lampshade is provided on the front side of the liner to match the light-emitting state of several LEDs; however, the structure of the car light mentioned above, Its effective light area is only the perforation of the light-transmitting cover and the reflecting groove, which means that the light needs to be reflected or directly irradiated to the light-transmitting cover or the perforation before the light can be projected from the light-transmitting body. The reflective groove is concave toward the light bulb and has a bowl-shaped shape, so the reflective groove at the end facing the light bulb will cause the light to be shielded, thereby affecting the light output efficiency; , It is difficult to achieve good brightness and projection distance, so it still cannot achieve the vision, brightness and projection distance of LED.

In view of this, our inventors are concentrating on further research on the mechanism of converting light sources into LEDs, and proceeding to research and development and improvement, hoping to solve the above problems with a better design, and after continuous testing and modification, there is a The advent of the present invention.

A light source 1, which is set on a lamp holder 2;

A light concentrator 3, which is connected to the light source 1; the light concentrator 3 protrudes toward the direction relative to the light source 1, and at least one light concentrating microstructure 31 corresponding to the light source 1 is protruded, and the light concentrator The microstructure 31 collects light in a full-circumferential space. The inner surface of the lamp holder 2 is provided with a reflective surface 21 corresponding to the light source 1 and the light-condensing microstructure 31, and the light concentrator 3 is correspondingly arranged on the The lamp holder 2; the light concentrating microstructure 31 has a light incident surface 311, a total reflection surface 312 and a light concentrating microstructure light exit surface 313; the light incident surface 311 is corresponding to the light source 1, the The total reflection surface 312 and the light-concentrating microstructure light-emitting surface 313 are arranged in correspondence with the light-incident surface 311, so that the light generated by the light source 1 enters through the light-incidence surface 311 and is directly emitted by the light-incident surface 311. light emitting from the light emitting surface 313 of the light concentrating microstructure, or perform total reflection between the light incident surface 311 and the total reflection surface 312 until the light is emitted from the light emitting surface 313 of the light concentrating microstructure; and,
