The present invention relates to a lighting device with a prior art that changes the illumination range. In today's general lighting technology, a reflector is used to reflect the light emitted by the light source, perhaps in combination with the refraction of the lens, and finally in a certain form. Required lighting. According to different usage requirements, the design with a small illumination range A is different.

U.S. Patent No. 517 Just 6 proposes a fixed parabolic reflector. The light source is moved in the direction of the optical axis to achieve the design of the zoom illumination (Fig. 2), and most of the (four) s. However, when the light source moves _ Wei Guocai, the _ surface miscellaneous will cause the reflected light to be emitted from the other half of the axis, and the angle between the optical axes of the domain is getting larger and larger, that is, the light will pass through the wire. This photo _ Fan Lion New Change, but the central brightness reduced the 'mystery empty _ situation. Lang Plane 69 paid for M326994 • The design uses a reflector and a lens to change the light due to the movement of the lens - the angle of refraction and the amount of light that can be controlled by the reflector to achieve the zoom effect (Figure 3), but the lens is connected The mechanism will block the light emitted by the light source, thus greatly reducing the efficiency of the lighting. [New Content] • The main purpose of this creation is to provide a lighting design that achieves lighting and focusing functions with good efficiency and low manufacturing costs. The creation includes an inner reflector, an outer reflector, and a light source. The inner and outer reflectors can be made of plastic, metal or other material that supports the reflective surface. The light source can be a led, incandescent, fluorescent or other form of light source. The light source is placed on the optical axis of the inner reflector, and the outer reflector can be placed outside the inner reflector, and the optical axis of the outer reflector is the same as the inner reflector. By moving the light source and the reflector on the optical axis, the angle of the light reflection and the ratio of the light controlled by the two reflectors can be adjusted to achieve the zoom effect. The inner reflector is a curved surface with a diverging function. The light is emitted by the light source, and after being reflected by the Φ inner reflector, combined with the light directly emitted by the light source, the uniform illumination effect can be formed. When the moving light source is forward, the incident angle of the light at the same position on the inner reflecting surface becomes smaller, and the reflection angle also becomes smaller, so that the angle between the emitted light and the horizontal becomes smaller. When the light source moves a certain distance, the light reflected through the inner reflector will be emitted at a large level, which is concentrated. In this way, the effect of the illumination zoom is achieved, and with the specially designed reflective surface of the creation, the reflected light, during the movement with the light source, will not be emitted from the other half of the optical axis, but in the same - Half and gradually near horizontal angles, ie the light will accumulate M326994 ^ in the center, so there will be no central voids in the whole process; compared to... In the previous technique, the design of the parabolic reflector was used. Empty, this creation has a better effect. However, this creation not only satisfies this zoom effect, but also expects to improve efficiency. When the light source moves forward, the light reflected through the inner reflector can be emitted horizontally, but the other part of the light, that is, directly emitted by the light source, also increases its proportion. This part of the light forms a wider range of pans. Light, but for some occasions, such as the searchlight 'requires to concentrate as much as possible' without the need for such a wide range of floodlights. Therefore, it is proposed to add an outer reflector design to reflect the directly emitted light and collect it. When the outer reflector moves forward on the optical axis, the light that passes through the edge of the inner reflector and directly emits light will hit more and more light to the outer reflector, and then through the special shape of the outer reflector, so that if the light is hit On this reflective surface will be emitted at a nearly horizontal angle. It can be seen that when the outer reflector moves forward, the more directly emitted light will be reflected by the outer reflector and become horizontally emitted, so the range of flood illumination gradually decreases, and the concentration of the light increases. > The advantage of this creation is that it achieves high-quality lighting with very few components, and the adjustable illumination range is quite large, with uniform, concentrated, and highly efficient lighting effects. Moreover, in actual production, unlike the design of the lens, high material cost and forming cost are required, and the polishing and polishing process is required to achieve good light transmittance, so the creation has great advantages in cost saving. This creation can be detailed in headlights, flashlights, light lamps and other lighting fixtures. [Embodiment] Referring to the fourth figure, the light source (1) can be an LED, an incandescent lamp or other different types of 7 M326994 light source 'inside reflector (2) placed in front of the light source, and has a special curved surface (201), such as double Surface or other surface. The outer reflector (3) has a special curved surface (301) with a reflective function, such as a hyperboloid or other curved surface. The small opening of the outer reflector is larger than the maximum outer diameter of the inner reflector, so the outer reflector can be placed over the inner reflector. The light (4) emitted by the light source (1) intersects the curved surface (201) at the point (p), and is reflected on the curved surface (201) to be emitted. At this time, the curved surface (201) is a diverging function, so the light (4) and other rays that are directed toward the curved surface (201) are reflected and their angles with the horizontal are greater than zero degrees. The light (5) is emitted by the light source and is not reflected by the inner reflector (2). When combined with the light reflected by the inner reflector (2), it can form a large area and uniform illumination in front. When the light source (1) moves forward, as shown in the fifth figure, it is emitted by the light source, and the light (6) intersects the curved surface (201) at the point (P), and is reflected on the curved surface (2〇1) to be emitted, as shown in the figure. At this time, as the incident angle decreases, the reflection angle also decreases. Therefore, the angle between the light reflected by the curved surface (201) and the horizontal level will approach zero, that is, the effect of light concentration. Light (7) is defined as the light that is just past the outermost edge of the inner reflector (2) and is not reflected by the inner reflector (2). Thus the angle between the light (7) and the horizontal defines the maximum angle of light emission. Before the light source (1) moves, the angle between the light (7) and the horizontal is the number a in the fourth figure. After the light source (1) moves, the angle is the number ^^ in the fifth figure, and b is greater than a, that is, the angle at which the light is directly emitted. Increased, so the range of maximum illumination has also increased. However, in some cases, such a large illumination range, such as a searchlight, is not required, so the design proposes a design that further reduces the illumination range and increases efficiency. When the outer reflector (3) moves forward, as shown in the sixth figure, the outer reflector (3) has a special curved surface (301) that emits light to the light source (1), which is emitted by reflection, and M326994 • _ The angle with the horizontal is extremely small. The light (7) passing over the outer edge of the inner reflector (2) will be reflected horizontally by the reflection of the outer _ and the reflector (3), defining the light (8) as the light that just passes over the outer edge of the outer reflector (3). At this time, the angle between the light (8) and the horizontal defines the maximum angle of light emission, which is (:, and (: is smaller than the number b in the second figure. Therefore, when the outer reflector (3) moves forward, the light that was originally directly emitted ( 7) The light and the line in the interval of the light (8) will be horizontally emitted by the reflection of the outer reflector (2), and a concentrated illumination will be formed in the front, that is, the light of the edge is collected to form a concentrated beam. Reduces the illumination in front _ range' to increase the efficiency of collecting light. Move the outer reflector (3) to collect the light emitted from the edge, which can play a role in the process of moving the zoom of the light source (1). It is shown that the light source (1) passes through the light (7) of the inner light cup (2) at any position of the zooming process, and will be horizontally emitted by the reflection of the outer reflector (3), and the light (8) is just passed over. The light on the outer edge of the reflector (2). So 'when the outer reflector (3) moves forward, the light that was originally emitted directly (7) to the light (8) The light in the interval will be reflected horizontally by the reflection of the outer reflector (3), forming a concentrated illumination in the front _ square.
