The following provides a detailed description of the lamp according to the present invention with reference to the accompanying drawings and specific embodiments.

Fig. 1, 2, and 3 show a preferred embodiment of the present application, which is a dome lamp, and includes a lamp body 11, a light source 15, a first light distribution element 14, a light-transmitting shielding plate 12, a reflector 1 as a second light distribution element, and a driving power supply (not shown). The power source driver may be a single component, and is disposed in the lamp body 11 and electrically connected to the light source 15 through a wire, a connector, and the like (the wire, the connector, and the like), or may be integrally disposed on the front or back of the light source module, or disposed outside the lamp body 11 for supplying power, which is not limited in this application.

Lamp body 11 has a cylindrical shape and includes a bottom plate 1101, side walls 1102, and an opening 1103 provided to face bottom plate 1101. In this embodiment, the lamp body 11 is an integrally formed metal member, which can protect the inside of the lamp well, and the connecting process of the bottom plate and the side wall is omitted, so that the lamp is more convenient to assemble, and the cost is reduced. The metal piece has good heat dissipation characteristics, and the light source 15 is fixed on the bottom plate 1101, so that heat generated by the light source can be quickly dissipated through the lamp body, and the service life of the lamp is prolonged. In order to enhance heat dissipation, a heat dissipation structure may be further installed outside the lamp body, in this embodiment, a heat sink is disposed at the bottom of the lamp, i.e., outside the bottom plate 1101, and in other preferred embodiments, heat dissipation fins may also be disposed on the side walls 1102.

The light-transmitting protection plate 12 is disposed in the middle of the lamp body 11, and divides the lamp body into an upper portion and a lower portion to form two separated accommodation spaces. The inner side of the light-transmitting protection plate 12 and the bottom plate 1101, and the sidewall 1102 therebetween form a first accommodation space a. The first accommodating space a is a space with certain dustproof and waterproof capabilities, and the light source 15 and the first light distribution element 14 are arranged in the protection space, so that the optical core component is protected. The outer side of the light-transmitting protection plate 12, the opening 1103 and the sidewall 102 therebetween form a second accommodating space B, and the reflector 13 is disposed in the second accommodating space B. In this embodiment, the reflector 13 is in a trumpet shape, a small opening end of the reflector serving as a light inlet is disposed close to the light-transmitting protection plate 12, and a large opening end of the reflector serving as a light outlet is flush with the opening 1103. In other preferred embodiments, the reflector 13 may also extend out of the opening 1103, and only a portion of the reflector is disposed in the second accommodating space B, which is not limited in this application. The reflector 13 is disposed outside the first accommodating space a with a protective effect, so that the reflector 13 can be conveniently replaced through the opening 1103 without opening the lamp, and the irradiation angle of the lamp can be changed by matching various reflectors 13, so that the lamp is more flexible in design.

In order to realize the installation and fixation of the light-transmitting protection plate 12, a step structure is formed on the inner side of the sidewall 1102, the step structure includes a bearing surface 1104 disposed opposite to the opening 1103, and the light-transmitting protection plate 12 is disposed on the bearing surface 1104. The light-transmitting protection plate 12 may be connected to the supporting surface 1104 by means of adhesion, fastening, or the like. In this embodiment, a screw hole is formed on the bearing surface 1104, the light-transmitting protection plate 12 is fixed on the bearing surface by a screw, the light-transmitting protection plate 12 can be used for fixing the first light distribution element 14, and the first light distribution element 14 is clamped between the light-transmitting protection plate 12 and the bottom plate 1101 after the installation is completed. A sealing element 17 is further interposed between the bearing surface 1104 and the light-transmitting protection plate 12, so that the light source 15 disposed in the first accommodating space a is protected by better waterproof performance. The sealing element 17 may be a sealing strip or a sealing ring.

The light-transmitting protection plate 12 is made of injection molding materials, has a protection effect and an optical effect, can change the transparency through the change of physical properties of the injection molding materials to form a transparent state or a semitransparent state, can be used for key illumination when the transparency is high, and can be used as a light homogenizing plate for environmental illumination when the semitransparent state is high. The same section guard plate has realized the demand of two kinds of applications of key illumination and ambient lighting under the simple injection molding material condition that has changed the guard plate, and the product appearance keeps unanimous, and product production need not additionally drop into, and is simple yielding, and the reaction is quick.

In this embodiment, the reflector 13 is connected to the lamp body 11 by a snap structure, which includes a plurality of snap portions disposed on the periphery of the reflector 13 and a retaining portion disposed on the inner wall of the lamp body 11 near the opening 1103. In other preferred embodiments, the reflector 13 and the lamp body 11 may be connected by other connecting structures, such as a screw or a connecting member such as a screw, which is not limited in this application. After the reflector 13 and the lamp body 11 are connected, a gap is formed between the small opening end of the light-transmitting protective plate 12 and the light-transmitting protective plate, mainly to prevent the reflector 13 from scratching the surface of the light-transmitting protective plate. A ring of baffles 1201 extending from the light-transmitting protective plate 12 to the opening 1103 is arranged on the periphery of the relative position of the light-transmitting protective plate 12 and the light inlet of the reflector 12, and the height of the baffles 1201 exceeds the distance from the light inlet of the reflector 12 to the light-transmitting protective plate 12. The upper end of the baffle 1201 is staggered with the inner lower edge of the reflector 12, so that a certain water blocking effect can be achieved, and the water-proof grade of IPX4 is achieved.

In the present embodiment, the first light distribution element and the second light transmission element are both reflective cups, and in other preferred embodiments, the first light distribution element and the second light distribution element may also be lens reflectors formed by integrally molding lenses, light guide elements and lens materials. The different choices of the reflector and the lens can generate a plurality of combination modes such as the reflector and the reflector, the reflector and the lens, the lens and the lens, and the like, thereby realizing a plurality of optical effects.

Fig. 4 and 5 show another preferred embodiment of the present application, which is a spot lamp including a lamp body 21, a light source 25, a light distribution element 24, a light-transmitting shielding plate 22, and a reflector 23.
