Description

Technical Field

[0001] The utility model belongs to the technical field of lamps, and in particular relates to a high-efficiency lamp structure. Background Art

[0002] "Lamp" is an appliance that can emit light and illuminate, and it plays a vital role in our daily lives. From ancient oil lamps and candles to modern electric lights and LED lights, the form and function of lamps have been evolving with the advancement of technology.

[0003] There are many types of modern lamps, which can be divided into many categories according to their purpose, shape, light source type, etc., including table lamps, chandeliers, wall lamps, ceiling lamps, floor lamps, street lamps, landscape lamps, etc. With the increasing awareness of environmental protection, energy-saving lamps are increasingly valued by people. LED lamps have become the mainstream choice of modern lighting due to their advantages such as high efficiency, energy saving, long life, environmental protection and pollution-free. In addition, the application of intelligent lighting systems has further improved energy efficiency and realized functions such as on-demand lighting and automatic dimming.

[0004] However, in some lamps, there is a certain distance between the light source and the lampshade, and the light generated will diffuse around inside the lampshade, which seriously affects the intensity of the light emitted and reduces the irradiation efficiency of the light source. Utility Model Content

[0005] In order to solve the technical problem in the prior art that light from the light source in the existing lamps will diffuse to the surroundings after being generated from the light source, resulting in low irradiation efficiency, the purpose of the utility model is to provide a high-efficiency lamp structure that can solve the above problem.

[0006] The technical solution for achieving the purpose of the utility model is: a high-efficiency lamp structure, including a light-transmitting cover, a light-collecting cover, a light source, a connecting piece and a lamp head, wherein the light-transmitting cover is installed on the lamp head through the connecting piece; the connecting piece has an installation cavity, and the light source is installed in the installation cavity; the light source faces the light-transmitting cover, and a light-collecting cover is also installed between the light-transmitting cover and the light source, and the light-collecting cover is used to gather light from the light source to irradiate in the direction of the light-transmitting cover.

[0007] In this solution, a condenser is added between the light source and the light-transmitting cover. Due to the existence of the condenser, the light generated by the light source can be constrained from spreading around. Under the action of the condenser, the light generated by the light source will irradiate the light-transmitting cover along the condenser. The light-transmitting cover is similar to a lampshade, which greatly improves the irradiation efficiency of the light source. The light-transmitting cover is installed on the lamp head through the connecting piece. The connecting piece can be made of metal aluminum, which not only plays the role of connection and installation, but also has a heat dissipation effect. With the existence of the connecting piece, the fixing structure between the lamp head and the connecting piece, and between the connecting piece and the light-transmitting cover is also more flexible, such as spiral, clamping, and bolt fixing.

[0008] Furthermore, the cross-section of the light-transmitting cover gradually decreases from the light source end toward the light-transmitting cover, so that light has no space to diffuse outward from the position where the light source is generated, and can only be reflected and transmitted toward the light-transmitting cover on the gradually shrinking inner wall of the focusing cover, which greatly improves the focusing effect of the focusing cover and the light irradiation efficiency of the lamp.

[0009] Furthermore, a light-transmitting cover is installed on the light-concentrating cover, and the light-transmitting cover has a mounting hole, and the light-transmitting cover is installed in the mounting hole. The light transmitted through the light-concentrating cover finally emits the lamp from the light-transmitting cover, and the light-transmitting cover is fixed to the end of the light-concentrating cover to further prevent the problem of light diffusion in the surroundings caused by adopting other structures. Only one mounting hole with a size corresponding to that of the light-transmitting cover is provided on the light-transmitting cover, and during installation, the light-transmitting cover is installed in the mounting hole.

[0010] Furthermore, the end of the condenser has a mounting portion, the light-transmitting cover is mounted on the mounting portion, the diameter of the light-transmitting cover is smaller than the diameter of the mounting portion, and a first mounting step is formed between the light-transmitting cover and the mounting portion; a second mounting step corresponding to the first mounting step is provided at the mounting hole, and the first mounting step is snapped onto the second mounting step. Specifically, the diameter of the mounting portion can be larger than the diameter of the end of the condenser, so that the first mounting step can be better formed and snapped onto the second mounting step; the second mounting step is located inside the condenser, and after the installation is completed, when the first mounting step and the second mounting step are snapped into place, the light-transmitting cover is also sealed and mounted inside the mounting hole, and from the outside, there is no gap or step, which is also more beautiful.

[0011] Furthermore, an elastic protrusion is provided on the second mounting step, and the elastic protrusion abuts against the outer peripheral side wall of the mounting portion. This has the advantage that the elastic protrusion has an inward clamping force on the mounting portion, and the condenser can be fixed on the light-transmitting cover without other fixing methods, and the fixing method is flexible and convenient.

[0012] Furthermore, the light-transmitting cover also has a mounting foot extending toward the connecting member, the mounting foot has an elastic hook, the inner wall of the connecting member has a hook groove corresponding to the elastic hook, and the elastic hook is installed in the hook groove. By using the cooperation of the elastic hook and the hook groove, the light-transmitting cover can be installed and fixed on the connecting member, and the fixing method is flexible and convenient, eliminating the need for additional drilling and fixing steps in the bolt fixing method, greatly improving the installation efficiency, and the fixing effect is also good.

[0013] Furthermore, a guide slope corresponding to the hook groove is provided at the end opening of the connecting member. Since the elastic hook is elastic and needs to be engaged in the hook groove, it is difficult to enter the connecting member due to the outward tension when it is initially entered, but it is more convenient under the action of the guide slope, and it can be pressed into the connecting member along the guide slope. And the guide slope corresponds to the hook groove, so the elastic hook can be engaged in the hook groove by entering vertically downward from the guide slope, completing the installation and fixation of the light-transmitting cover and the connecting member.

[0014] Furthermore, the inner wall of the connecting member is provided with an inwardly protruding limiting convex strip and a first limiting groove, and the light-transmitting cover is provided with a second limiting groove and a protruding block that respectively correspond to the limiting convex strip and the first limiting groove, the limiting convex strip is installed in the second limiting groove, and the protruding block is installed in the first limiting groove. In order to prevent the light-transmitting cover from rotating axially after being installed in the connecting member, and to facilitate the installation of the elastic hook and the hook groove, corresponding limiting devices are further provided on the inner wall of the connecting member and the light-transmitting cover, respectively, to improve the installation efficiency and the fixing effect after the overall installation.

[0015] Furthermore, the lamp also includes a heat dissipation support, which is installed in the connecting member, the light source is installed on one side of the heat dissipation support, and a power supply (21) is installed on the other side of the heat dissipation support, and an electric wire is connected between the power supply (21) and the light source. As for the specific fixing structure of the heat dissipation support in the connecting member, it can be that the connecting member has a partition, the bottom of the heat dissipation support has a flange portion, and the flange portion is glued to the partition, or it can be that the connecting member has a convex portion protruding inward, and the flange portion is glued to the convex portion. The light source structure can also be in various forms, such as lamp beads installed on an LED light-emitting board, or a COB light source. The heat dissipation support plays the role of installation and fixing, and the power supply (21) and the light source are installed separately; at the same time, its material can be metal aluminum, which can effectively dissipate heat while supporting the installation, thereby increasing the service life of the lamp.

[0016] Furthermore, the model of the lamp holder is E14, or E27, or GU10, and the model can be freely switched according to actual use needs, which has stronger adaptability.

[0017] Furthermore, the outer wall of the connecting piece also has an external thread, which facilitates the installation of the lamp on other devices.

[0018] By adopting the above technical solution, the utility model has the following beneficial effects:

[0019] (1) Adding a condenser between the light source and the light-transmitting cover can prevent the light generated by the light source from diffusing to the surroundings, resulting in low irradiation efficiency;
