[0002] Traditional high-power lamps for lighting, such as lamps, general-purpose lamps, factory lamps, etc., generally have inner covers made of ordinary aluminum sheet materials with an arc-shaped concave plane. The aluminum has poor reflection efficiency and cannot reflect the light source into a more effective light source for use. Currently, the internal structures of high-power traditional lamps are similar except for the different appearances.

The lamp with a multi-mirror beam-gathering reflector is provided with a plurality of protrusions inside the reflector cover, each protrusion can be used as a small reflective mirror, which can not only provide the strength of the reflector cover, but also increase the reflection efficiency, so that the light emitted by the lamp is emitted from the lamp cover more and more evenly, and energy-saving, environmental protection and pollution-free light distribution are achieved.

[0010] The second lens is composed of two upper and lower Fresnel lenses with different optical powers, and the optical power of the upper lens is greater than that of the lower lens.

[0011] Among them, the multiple lenses of the first lens group are divided into high beam lenses and low beam lenses, and the combinations of the high beam lenses and the low beam lenses are different.

[0019] See also Figure 1-Figure 4 , Figure 1 is a schematic diagram of the structure of the utility model (wherein the first lens group 3 is removed). Figure 2 It is a structural schematic diagram of another direction of the utility model. Figure 3 It is a schematic diagram of the second lens (Y bracelet surface) and the connecting piece of the utility model. Figure 4 It is a schematic diagram of the high and low beam areas of the utility model, a multi-light source transmission type cluster lamp, including a substrate 1, a light source 2, a first lens group 3, a connecting piece 4 and a second lens 5; the light sources 2 are respectively arranged on one side of the substrate 1, the first lens group 3 is arranged on the outside of the light source 2, the connecting piece 4 is fixedly connected to the substrate 1, and is located on the side of the substrate 1 close to the first lens group 3, and the second lens 5 is fixedly connected to the connecting piece 4, and is located on the side of the connecting piece 4 away from the substrate 1.

[0020] In this embodiment, the substrate 1 provides installation conditions for the luminous light source 2, the first lens group 3 and the connecting member 4. The connecting member 4 is used to connect the second lens 5 with the substrate 1, so that the second lens 5 is located on the light-emitting side of the first lens group 3. The first lens group 3 is used to collect the light emitted by the luminous light source 2 to the maximum extent. The optical focal length of the first lens group 3 in the horizontal direction is greater than the optical focal length in the vertical (up and down) direction, and the light is evenly distributed in space. The shape and size of the first lens group 3 can be optimized and designed according to the characteristics of the luminous light source 2 (such as light-emitting angle, brightness, etc.) to achieve the best light scattering effect. The second lens 5 modulates the light in the up and down (vertical) direction of the lens, and does not modulate the light in the horizontal direction, so that the light emitted by each of the light sources can share the second lens 5 lens, and the light beams overlap on the second lens 5 to the maximum extent, which is significantly different from the traditional method that each light source passes through a different second lens 5. In this way, when multiple light sources are used at the same time, the lateral size of the second lens 5 becomes the smallest, which is conducive to the compactness and cost reduction of the entire system. At the same time, the appearance is more coordinated and beautiful, and the problems of uneven light, uncontrollable emission direction, and large space occupation of the lamp are solved.

[0021] Furthermore, there are multiple light sources 2 arranged in a straight line.

[0022] In this embodiment, the light source 2 can be an LED or other type of light-emitting element, arranged in a certain layout. Multiple light sources 2 can be arranged in a straight line, or in a ring, matrix or other layout to achieve different lighting effects according to specific needs.

[0023] Furthermore, the first lens group 3 includes a plurality of lenses corresponding to the light source 2, the shape of the first lens group 3 is elliptical, and the optical focal length of the first lens in the horizontal direction (X-axis) is greater than the optical focal length in the vertical direction (Y-axis).

[0024] In this embodiment, the shape of the first lens group 3 is elliptical, and the shape and size can be optimized according to the characteristics of the light source 2 (such as light emitting angle, brightness, etc.) to achieve the best light scattering effect.

[0025] Furthermore, the second lens 5 is a rectangular lens having optical power only in the vertical direction, and the incident surface is a plane or a Y-bracelet surface, and the exit surface is a Fresnel serrated surface in the vertical direction; the second lens is composed of two upper and lower Fresnel lenses with different optical power, and the optical power of the upper lens is greater than that of the lower lens, and the multiple lenses of the first lens group are divided into high beam lenses and low beam lenses, and the combinations of high beam lenses and low beam lenses are different.

[0026] In this embodiment, the width and height of the second lens 5 can be adjusted according to the light-emitting characteristics of the first lens group 3. The incident surface of the second lens 5 is a plane or a Y-bracelet surface with optical focal length only in the vertical direction. The purpose of this is to ensure that the light beams emitted by multiple light sources arranged in a horizontal straight line through the first lens group 3 maintain a consistent surface shape on the incident surface of the second lens 5. In other words, the light beams emitted by multiple light sources can fully overlap on the incident surface of the second lens 5, and the transmission of the light beams will not be disturbed by the overlap. This can achieve the maximum integration of multiple light sources within a limited width range, which is an unavoidable problem in traditional optical lighting systems. The Fresnel serrated surface (exit surface) of the second lens 5 only exists in the vertical direction. The optical focal length can make the second lens 5 focus in the Y-axis direction and not focus in the X-axis. The shape, size and number of the serrated protrusions 6 of the Fresnel serrated surface can be optimized through optical simulation to ensure that the light can be emitted with maximum efficiency. In addition, the exit surface of the second lens 5 can also be a Y-bracelet surface, and the Y-bracelet surface also has optical focal length only in the vertical direction, which has the same function as the Fresnel serrated surface. The difference is that the manufacturing cost is lower and it is more in line with the interests of the enterprise. The middle is the low beam area and the two sides are the high beam areas. The number of low beam lenses and high beam lenses can be designed according to user needs, such as: 5 low beam lenses, 2 high beam lenses, or 3 low beam lenses, 4 high beam lenses. The Fresnel lens of the second lens can have different surface shapes or tooth shapes according to the different high beam areas or low beam areas.

[0027] The above disclosure is only a preferred embodiment of a multi-light source transmission-type focusing lamp of the present application, and cannot be used to limit the scope of rights of the present application. Ordinary technicians in this field can understand that all or part of the processes of implementing the above embodiments and equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
