Description

Light source conversion system

The invention provides a light source conversion system, in particular, a light source capable of forming a large-area light source of a conventional lamp, and making a lamp equivalent to an LED lamp effect or at least a small illuminant, such as a conventional light guide lamp.

According to the light, light has been widely used in various fields and technologies. In order to improve luminous efficiency and reduce energy consumption, LED (Light-Emitting Diode) has been widely used to replace traditional lighting components, although LED has a long life. Long, low power consumption and high luminous efficiency, however, LED is expensive, its price is much higher than traditional bulbs, and the LED's power conversion efficiency is only 15 to 20% converted to light energy, and 80 to 85%. It is converted into heat energy, and the temperature rise of the LED will cause its luminous efficacy to decline. Among them, the degree of decline of yellow light is the most significant. Therefore, LEDs often need to be equipped with a heat sink to maintain the luminous efficiency, which makes the cost of LED more expensive.

Therefore, the utility model provides a "light bulb type lamp with LED vision" as disclosed in the Republic of China Certificate No. M307544, which discloses a bulb type lamp with LED vision, which comprises: a lamp holder; a bulb, which is mounted on the lamp holder.

Light transmission The system is made of a transparent material and has a spherical shape. The light generated by the bulb is reflected by the refracting surface of the inner edge of the lamp holder, and then projected from the light-transmitting body formed in the perforation of the lamp frame, because the lamp frame is arranged around the lamp frame. The tapered wall allows the light to be projected on the tapered wall to refract light, so that it has the effect of collecting light, so that the light bulb can also have the visual effect of LED illumination; however, the LED light bulb type vehicle In the case of the lamp, the effective light zone only has the perforation of the lamp frame, which means that the light needs to be reflected or directly irradiated to the perforation to project light from the light-transmitting body. It is worth noting that the lamp frame is directed toward The bulb is recessed to form a tapered wall, and the tapered wall is only attached to one end of the light transmitting body, so that the light emitted by the light transmitting body can be concentrated and projected, and the other end of the tapered wall will be The light is blocked by the concave tapered wall, thus affecting the light-emitting efficiency; in addition, the light-collecting effect of the light-transmitting body alone is difficult to achieve good brightness and projection distance, so it still cannot achieve the vision such as LED , brightness and throw distance.

The invention also provides a "lighting device capable of multi-light spot", such as the Republic of China Certificate No. M298539, which discloses a lamp device capable of multi-light spot, comprising: a lamp holder having a concave seat a reflector, a reflective coating on the inner surface of the housing; a bulb located at the bottom of the base of the socket; and a light transmissive lamp unit having a lampshade attached to the base of the socket And a light-emitting point plate interposed between the lamp cover and the light bulb, the light-emitting point plate has a plate body, a plurality of concave cups formed on the plate body and recessed toward the bulb direction, and a plurality of a concentrating column protruding from the bottom of the inner surface of the plurality of concave cups toward the lampshade, the light of the bulb being condensed on the concentrating column through the concave cup body, so that each concentrating column Forming a light spot; thereby, as shown in the fifth figure of the light-emitting device of the multi-light spot, the light generated by the light bulb can be projected by the concave cup or the concentrating column, thereby achieving the simulated light-emitting LED The illuminating effect, and the concave cup body has a cup bottom adjacent to the bulb, and a cup surrounding the bottom edge of the cup and the plate body, the thickness of the bottom of the cup is greater than the thickness of the circumference of the cup, so that The light emitted by the bulb has more parts concentrated on each concentrating column; however, it does not completely concentrate the light on the concentrating column and is projected, and some of the light is directly emitted from the concave cup body. Therefore, it is still impossible to effectively achieve the visual, brightness and projection distance of the LED.

The utility model also provides a "light structure" of the Republic of China Certificate No. M281838, which is provided with a reflector in front of the lamp housing, the front end mask of the reflector is provided with a plurality of reflective surfaces for reflecting light, and the reflector is The front side is provided with a light bulb, and a lining plate is arranged in front of the reflector, and a transparent cover is arranged at the center of the lining plate, and a plurality of transparent covers are formed from the front side to the rear and are provided at the rear end. The reflecting groove portion of the perforated hole is formed, and the direction of each reflecting groove portion is corresponding to each reflecting surface of the reflecting cover, and the reflecting end surface of the reflecting groove portion is provided with a plurality of reflecting surfaces for reflecting light, and another has a transparent surface The light plate group is disposed in the aforementioned perforation, and finally a light-transmitting lamp cover is arranged on the front side of the lining plate; thereby generating a state in which several LEDs emit light; however, in the case of the lamp structure, the effective light area is only transparent. The perforation of the mask and the reflective groove portion means that the light needs to be reflected or directly irradiated to the transparent cover or the perforation to project light from the transparent body. Further, the reflective groove portion is concave toward the bulb direction. Into the shape of a bowl, so the opposite The slotted portion faces the light bulb At the end, the light will be shielded, which will affect the light-emitting efficiency. In addition, the light-collecting effect of the light-transmitting body alone is difficult to achieve good brightness and projection distance, so it still cannot achieve the vision, brightness and projection of the LED.
