[0002] With the high-speed development of lighting application, the state vigorously promotes the development of night economy, although the quantity of lighting market demand is more and more big, but the control of lighting quality is not satisfactory. Applicant thinks that: the improvement of lighting level should not be limited to the dynamic improvement of brightness and color, and should focus on the improvement of lighting quality, such as focusing on human factors, focusing on health, focusing on the harmony of architecture and light.

[0003] Analysis of current LED lighting technology, direct lighting is one of the main reasons for light pollution, and in direct lighting, the unreasonable selection of optical device is one of the main reasons for low lighting level. Although the mainstream advocates the lighting mode of seeing light without seeing lamp, but floodlighting widely uses LED lamps, which are all direct lighting mode, i.e. the lamp emits light directly to the illuminated surface. The direct light of the lamp will produce serious glare.

[0004] The development of LED lighting technology also brings the diversification of optical accessories, including optical lens and reflector cup. The structure of traditional reflector cup 7 generally tends to the structure design as shown in Figure 1 The internal reflection surface has fixed curvature, and the light distribution is symmetrical light distribution. The light source light mainly includes reflection part and direct part. The path of light reflected by the light source light and light beam of the reflector cup is as shown in Figure 1 There are direct light and reflected light in different design angles. The reflected light is processed to effective light 8, and the light of direct light cannot be effectively used, becoming stray light 9 or light pollution, forming secondary light spot on the illuminated surface.

[0005] In combination with the above prior art, it can be known that the existing reflector cup causes the application scene of lamp to have limitation, and the defects brought by it are:

[0006] In the scene of special lighting demand, for example, the lamp is forced to be set obliquely to illuminate the illuminated object due to the physical structure of the scene. At this time, the lamp as a whole needs to be inclined to illuminate, so that the light source, light outlet or whole of the lamp directly aims at the illuminated surface, and the light directly shining into the eyes will greatly increase, which will produce glare. In the structure layer, it is difficult to present the oblique setting of the lamp to pedestrians in a hidden way, so it is difficult to realize the harmonious lighting effect of seeing light without seeing lamp.

[0057] Embodiment 2

[0058] Figure 11 ​​​​As shown, in Embodiment 2, an installation structure for assembling any of the reflectors described in Embodiment 1 is provided. The installation structure includes an aluminum substrate 4 and the positioning support 11. The aluminum substrate 4 is provided with mounting slots 41 that match and are inserted into the positioning support 11. The number of mounting slots 41 is equal to the number of positioning supports.

[0059] In this embodiment, a positioning support is provided at the end of the cup holder away from the cup body. On the same horizontal plane, an abutment edge is provided on the outer periphery of the cup opening. The positioning support is matched and inserted into the mounting groove on the aluminum substrate. A pressure plate is pressed onto the surface of the abutment edge. The light-transmitting hole is positioned opposite to the cup opening, enhancing the structural stability of the reflector cup within the lamp. By opening a light-transmitting hole in the pressure plate, with the light-transmitting hole positioned opposite to the cup opening, the pressure plate ensures that while pressing down on the abutment edge of the reflector cup, it does not structurally interfere with the oblique reflection of the light beam in the reflector cup onto the illuminated surface. The illumination area partitioning diagram of the illuminated surface is shown below. Figure 10 As shown, specifically: the light emitted by the LED light source is reflected to the illuminated area A1 after passing through the first free reflection surface; the light emitted by the LED light source is reflected to the illuminated area B1 after passing through the second free reflection surface; the light emitted by the LED light source is reflected to the illuminated area D1 after passing through the third free reflection surface; and the light emitted by the LED light source is reflected to the illuminated area C1 after passing through the fourth free reflection surface.

[0063] In this embodiment, the pressure plate is pressed onto the surface of the abutment edge, and the light-transmitting hole is positioned opposite to the cup opening, which enhances the structural stability of the reflector cup within the lamp. By opening the light-transmitting hole on the pressure plate, and positioning the light-transmitting hole opposite to the cup opening, the pressure plate ensures that while pressing down on the abutment edge of the reflector cup, it does not structurally interfere with the oblique reflection of the light beam in the reflector cup onto the illuminated surface.

[0064] The working principle and process of this application:

[0065] Step 1: The LED light-emitting chip of this application is mounted onto the surface of the aluminum substrate using SMT technology and is located at the geometric center of the three mounting slots;

[0066] Step Two: As Figure 11 As shown, the reflector cup of this application is connected to and fixed on the aluminum substrate by three positioning supports at the bottom through mounting slots.

[0067] Step 3: As Figure 10 As shown, the LED lamp and its built-in reflector of this application are positioned to the right of the illuminated surface;

[0068] Step 4: The light emitted by the LED light source approximates a Lambertian volume, emitting light uniformly in space at a predetermined angle.

[0069] Step 5: The light emitted by the LED light source is obliquely reflected to the illuminated area A1 after passing through the first free reflection surface; the light emitted by the LED light source is obliquely reflected to the illuminated area B1 after passing through the second free reflection surface; the light emitted by the LED light source is obliquely reflected to the illuminated area D1 after passing through the third free reflection surface; the light emitted by the LED light source is obliquely reflected to the illuminated area C1 after passing through the fourth free reflection surface.

[0070] Step Six: Each free-reflecting surface, i.e. the reflector cup of this application or the inner surface of the reflector cup of this application, is integrally formed by injection molding to achieve uniform light spot.
