[0001] The utility model relates to the technical field of lamps, in particular to a ridge type reflective bowl high and low beam lamp. Background Art

[0002] LED lights are widely used because of their energy saving and long service life. In order to control the illumination range of LED bulbs and make them focus, people usually install reflective bowls in front of LED bulbs. However, most of the reflective bowls nowadays are integral curved surfaces, and the reflective bowls with integral curved surfaces are sleeved on the front ends of multiple LED bulbs to carry out focused and fixed-point illumination of the LED light group.

[0003] Traditional reflective bowl lamps usually use a single light source in combination with a lens or a reflective bowl to achieve light irradiation, but this method is difficult to achieve high-power lighting due to heat dissipation limitations. Utility Model Content

[0004] The utility model aims to provide a ridge-type reflective bowl high and low beam lamp, aiming to solve the problem that traditional reflective bowl lamps are difficult to achieve high-power lighting due to the limitation of heat dissipation.

[0006] The roof-type reflective bowl is divided into two reflective surfaces, an upper reflective surface and an lower reflective surface, including a low beam reflective area and a high beam reflective area.

[0007] Among them, the incident surfaces of the multiple lenses are all planes, and the multiple lenses divide the light emitted by the light source into upper and lower parts through total reflection, and transmit them to the upper and lower reflecting surfaces of the ridge-type reflective bowl respectively.

[0008] Wherein, the ridge-type reflective bowl high and low beam lamp further comprises a heat dissipation fin, and the heat dissipation fin is fixedly connected to the shell and is located on one side of the shell.

[0009] Wherein, the ridge-type reflective bowl high and low beam lamp further comprises a protection plate, which is fixedly connected to the shell and is located on a side of the shell away from the heat dissipation fins.

[0010] Wherein, the ridge-type reflective bowl high and low beam lamp further comprises a plurality of positioning heads, and the plurality of positioning heads are respectively fixedly connected to the shell and are all located on a side of the shell away from the heat dissipation fins.

[0011] Wherein, the heat dissipation fins and the protection plate are fixed to the housing by using a plurality of fixing bolts.

[0012] The utility model discloses a ridge-type reflector bowl high and low beam lamp, comprising a housing, a plurality of light sources, a plurality of lenses and a ridge-type reflector bowl, wherein the plurality of light sources are respectively fixedly connected to the housing and are all located in the housing, the plurality of lenses are respectively fixedly connected to the housing and are all located on one side of the housing close to the light sources, and the ridge-type reflector bowl is fixedly connected to the housing and is located in the housing. The light beam emitted by the light source is transmitted to the upper and lower reflective surfaces of the ridge-type reflector bowl through total reflection of the plurality of lenses, and the high beam or low beam mode of the emitted light is ensured by changing the surface shapes of the upper and lower ridge reflective surfaces. The housing provides installation conditions for the plurality of light sources, the plurality of lenses and the ridge-type reflector bowl, the plurality of light sources are respectively located at appropriate positions of the housing for emitting light, the plurality of lenses are respectively corresponding to the plurality of light sources, the plurality of lenses are completely the same in size and surface shape, and are used for total reflection transmission of the light emitted by the light source, so as to improve the utilization rate of the light and the lighting effect. The ridge-type reflector bowl is located at the upper and lower sides of the housing for receiving the light processed by the lens, and guiding the light into a horizontal direction through its reflection. The design of the ridge-type reflective bowl should ensure that the light can be evenly distributed to avoid dark areas or bright spots. The light emitted by the multiple light sources is first processed by the multiple lenses, so that the light has a certain directionality and uniformity during the propagation process. Then, the light is transmitted to the ridge-type reflective bowl, and the light is guided into a high-beam or low-beam emission mode through the reflection effect of the ridge-type reflective bowl. Due to the superposition of multiple light sources, this design can ensure that the light is evenly distributed in scenes such as ridges or eaves that require horizontal light irradiation, thereby improving the lighting effect. The upper and lower reflective covers are ridge-shaped, and their surface shape can be adjusted to high-beam lighting or low-beam lighting according to the lighting effect. That is to say, the light emitted by the multiple light sources passes through the multiple lenses. The reflected output light can realize high beam and low beam lighting only by adjusting the upper and lower roof surfaces. A plurality of light sources are arranged side by side at the bottom of the shell, and the high beam light source and the low beam light source are arranged side by side nearby. In this way, it can be ensured that the reflection areas of the high beam and the low beam on the roof surface are superimposed on each other, so that the size of the roof surface is minimized, and the high beam reflection area and the low beam reflection area have a smooth transition. From the appearance of the whole system, the high beam and the low beam lighting use the same roof reflection bowl, and the overall appearance is more coordinated and beautiful, realizing high-power lighting and excellent heat dissipation, thereby solving the problem that traditional reflective bowl lamps are difficult to achieve high-power lighting due to the limitation of heat dissipation.
