detailed description

Referring to Figures 1 to 5, a surface-mounted downlight includes a lamp body 10, a light source 11 is disposed inside the lamp body 10, and a light outlet 12 for the light of the light source 11 to pass through is opened at the bottom of the lamp body 10, and the light output The opening 12 is covered with a light-transmitting plate 13 , and the top surface of the light-transmitting plate 13 is provided with a plurality of transverse light-transmitting convex strips 131 . Since the top surface of the light-transmitting plate 13 is provided with transverse light-transmitting convex strips 131 in the utility model, the light of the light source 11 can be diverged to a certain extent, and the number and arrangement of the light-transmitting convex strips 131 can be adjusted. A variety of different lighting effects can be realized, and the lighting range of the surface-mounted downlight can be increased, which is more beautiful and practical. In this embodiment, the light-transmitting convex strips 131 are evenly arranged side by side on the light-transmitting plate 13 so that the top surface of the light-transmitting plate 13 is wavy, so that the projected shape of the light of the surface-mounted downlight is elliptical, which can also To make the light emitted by the surface-mounted downlight more uniform. In addition, the light-transmitting plate 13 and the light-transmitting convex strip 131 in this embodiment are a whole piece of glass plate after processing. This shape is also convenient for processing and production. Of course, practical applications It is also possible to flexibly adjust the number and distribution of the light-transmitting convex strips 131 according to needs to change the projection shape of the light. The light-transmitting convex strips 131 can also be separated from the light-transmitting plate 13 and fixed on the light-transmitting plate by bonding or the like. 13 on. A condensing lens 14 is arranged below the light source 11, and the condensing lens 14 includes a light-transmitting connecting plate 141 and at least a small lens 142 arranged at the rear end of the connecting plate 141. The rear portion of the small lens 142 is bowl-shaped and covered. On the light source 11, the front part of the small lens 142 is in the shape of a convex lens, which can reduce the scattering of light, make the light more concentrated, and improve the light efficiency. , in addition, there is a condenser cup 15 arranged between the light source 11 and the light outlet 12, which can gather the light from the light source 11 to the light outlet 12 and emit it, thereby improving the light efficiency of the surface mounted downlight.

The light source 11 in this embodiment is a plurality of LED lamp beads arranged at the bottom of a substrate 16, and a heat sink 17 aligned with the LED lamp beads is fixed on the top of the substrate 16. A separate power adapter is usually used in traditional downlights to convert the current of the external power supply into a current suitable for LED lamp beads. The power adapter is large in size, high in cost, and difficult to install. In the embodiment, the power adapter components are integrated on the base plate 16, which effectively reduces the volume of the surface-mounted downlight, facilitates assembly, and reduces production costs. The power adapter components in this embodiment are similar to traditional power adapters, including transformer components 161 and rectifier components 162, usually composed of electrical components such as resistors, capacitors, rectifier bridges, power tubes, etc., which are commonly used in this field The structure is not described in detail here. In practical applications, the power adapter components may also include other commonly used electrical components such as fuses, etc., and are not limited thereto.

The top of the substrate 16 is closely attached to a heat sink 17 that is aligned with the LED lamp beads. The heat generated by the LED lamp beads during operation can be conducted from the substrate 16 to the heat sink 17 and dissipated by the heat sink 17 to prevent the LED lamp beads from overheating. Correspondingly, the substrate 16 can be made of materials with better thermal conductivity such as metal to improve heat dissipation efficiency. In this embodiment, aluminum is used to manufacture the substrate 16, which is lighter in weight and firmer at the same time, and the cost is lower and convenient. Processing, good thermal conductivity. The lamp body 10 includes an insulating shell, and the base plate 16 and the radiator 17 are both arranged in the inner cavity of the insulating shell, which can prevent electric shock and ensure safe use.

The traditional surface-mounted downlight usually directly fixes the lamp body 10 on the ceiling, and it is inconvenient to disassemble. Clamping groove 21, the longitudinal section of the clamping groove 21 runs through the bottom surface of the connecting seat 20, the lamp body 10 is provided with a clamping piece 18 matching the clamping groove 21, and the clamping piece 18 is inserted into the bottom surface of the clamping groove 21 The lamp body 10 is fixed on the connecting seat 20 in the horizontal section, and the lamp body 10 can rotate and move down relative to the connecting seat 20 so that the clip 18 slides along the clipping groove 21 to disengage from the clipping groove 21 so that the lamp body 10 Detach from the connecting seat 20, first fix the connecting seat 20 on the ceiling or wall with screws 22, etc., and then tighten the lamp body 10 to the connecting seat by using the cooperation of the clamping groove 21 and the clamping piece 18 20, the lamp body 10 can also be easily disassembled, easy to replace and repair the lamp body 10, and easy to use. Of course, the positions of the clamping groove 21 and the clamping member 18 can be interchanged in practical applications.

The above descriptions are only the preferred implementation modes of the present utility model, as long as the technical solutions that achieve the purpose of the utility model by basically the same means all fall within the scope of protection of the utility model.
