Description

A solar lawn lamp

technical field

The utility model belongs to the technical field of lighting equipment, in particular to a solar lawn lamp for courtyards and gardens.

Background technique

The design of the lawn lamp mainly adds safety and beauty to the urban green landscape with its appearance and soft lighting, and generally has the characteristics of easy installation and strong decoration. It can be used for decoration of green belts in parks, garden villas, square greening, and other places. illumination. Lawn lights developed to the 1990s and were widely used in urban slow lanes, narrow lanes, residential areas, tourist attractions, parks, squares, private gardens, courtyard corridors and other public places on one or two sides of the road for road lighting. Improving the safety of people traveling at night is used to increase the time of people's outdoor activities and improve the safety of life and property. It can also change people's mood, elevate people's emotions, and can change people's perceptions, creating a night like a palette of light and dark. During the day, lawn lamps can embellish the city scenery; at night, lawn lamps can not only provide the necessary lighting and living convenience, increase the sense of security of residents, but also highlight the city's highlights and perform a bright style, so that it is still in use today. At present, with the development of solar technology, solar technology is also widely applied to lawn lamps.

But the light reflection structure of the solar lawn lamp of prior art is CN 202902157 U as the publication number, and the light distribution structure of the lawn lamp disclosed in the Chinese utility model patent publication of the name is the light distribution structure of lawn lamp, including being placed in the work The secondary optical element on the surface and reflects the light emitted by the light source part upwards, and also includes a reflector placed above the secondary optical element and reflects the light from the light source part to the working surface and the publication number is CN 201964281 U , a crystal lawn lamp using a high-power LED light source disclosed in the Chinese utility model patent publication named a crystal lawn lamp using a high-power LED light source, including an LED light source, a lamp body and an installation at the bottom of the lamp body Chassis, the crystal lawn lamp also includes a crystal glass astigmatism lampshade, the LED light source is a high-power LED, and a metal shell connector for heat dissipation is provided between the crystal glass astigmatism lampshade and the lamp body, and the LED light source is fixed on the metal In the housing connector, the top inner wall of the crystal glass astigmatism lampshade is provided with a reflective metal sheet or a silver-plated reflective layer; but these two light sources are located below the light reflective structure, and some of the light emitted by the light source cannot reach At the lampshade, the range of light distribution is small, which also causes a waste of light energy. In order to make up for the lost light energy, the power of the light source is increased to meet the brightness requirements of the product when it is used, which causes a waste of electric energy. Therefore, there are problems of insufficient brightness and high energy consumption. For example, the publication number is CN 201081136 Y, and a Chinese utility model patent publication titled a high-power LED solar lawn lamp with a waterproof socket discloses a high-power LED solar lawn lamp with a waterproof socket, including solar panels, The tray, the disc and the circular tubes connected in sequence, the connector, the top cover, the radiator, the high-power LED, the transparent sheet, the lampshade, the reflector, the lampshade support, the shell, the rubber gasket and the bottom cover, in the shell The middle and lower part of the body is installed with an AC power supply system independent of the high-power LED solar lawn lamp and a waterproof socket that can directly introduce AC power to the electrical appliances. A plastic plate is connected to one end of the round tube. Charge and discharge controllers, batteries and LED drivers are placed above the board, and the solar panel is set above the tray; although the light source is located above the reflector, due to the blocking of the lampshade holder and the reflector, the light cannot reach the area below the reflector. In some parts, the range of light distribution is still small, and the light is uniform up and down, and the light and shade are obvious, and both the reflector and the lampshade need to be supported by a lampshade holder, so the structure is more complicated and the preparation cost is relatively high.

Utility model content

Aiming at the above problems, the utility model provides a solar lawn lamp with relatively large light distribution range, uniform light distribution, simple structure and relatively low cost.

The technical scheme used by the utility model to solve the above problems is to provide a solar lawn lamp with the following structure, which includes a lamp body, a lampshade and a solar module, the lower end of the lampshade is connected to the lamp body, and the upper end of the lampshade is connected to the solar module. The lower end of the solar module in the lampshade is provided with a light source, and there are at least two light sources, the lower end of the solar module in the lampshade is also provided with a first reflector, and the light source is evenly distributed around the first reflector , a second reflector is arranged in the lampshade below the first reflector.

After adopting the above structure, compared with the prior art, the utility model is provided with the first reflector and the second reflector, and they are arranged one above the other, and the light source is uniformly distributed around the first reflector, the light emitted by the light source Under the action of the first reflector and the second reflector, it is refracted onto the lampshade, and there is no shelter in the lampshade, so that the light spreads in a wide range, and the overall light distribution is relatively uniform, and the waste of light energy is relatively low. The original photomask carrier is removed, the structure is simpler, and the preparation is convenient, thereby reducing the production cost. Therefore, the utility model has the characteristics of relatively large light distribution range, relatively uniform light distribution, simple structure and relatively low cost.

As an improvement, the centerline of the first reflector and the centerline of the second reflector are on the same vertical line; after such arrangement, the light can be evenly reflected by the second reflector, so that the circumferential distribution of light is more uniform , so the uniformity of light distribution can be further improved, and the use effect of the utility model can be improved.

As a further improvement, the cross-section of the first reflector is a "chevron" structure; then the first reflector with this structure can scatter light relatively well, which can improve the uniformity of light distribution in the lampshade, And the structure is relatively simple, and the preparation cost is also low.

As a further improvement, the cross-section of the second reflector is the same as that of the first reflector, and the diameter of the upper end of the second reflector is smaller than the diameter of the lower end of the second reflector; The mold opening of the second reflector can not only reduce the production cost of the second reflector, but also improve the uniformity of light distribution in the lampshade.

As a further improvement, the diameter of the lower end of the second reflector is equal to the inner diameter of the lampshade; after such setting, the light at the lower end of the lampshade can be refracted by the second reflector, so that the light distribution in the lampshade is more uniform, and The utilization rate of light energy is also further improved.

As a further improvement, the lower end surface of the first reflector is attached to the upper end surface of the second reflector, so that all the light rays between the first reflector and the second reflector are also refracted out of the lampshade, eliminating the original When there is a gap, the light in the middle part is not easy to be refracted out of the lampshade, so that the uniformity of the light intensity outside the lampshade and the light distribution are better, and the use effect of the utility model is further improved.

Preferably, there are four light sources.
