As the market blows into the market, development is becoming clearer. The situation of many companies rushing to the LED market has been out of control. Although the LED industry has developed rapidly in recent years, it still lacks authoritative technical standards, which has led to the unevenness of the entire industry and is very unfavorable for large-scale promotion. In the case of LED street lamps with relatively high technical difficulty, the problems caused by the lack of technical standards are particularly obvious. Many of the best LED manufacturers and do not know how to design a practical, application department can not tell the specific requirements. For example, many manufacturers have designed a "short-type" lampshade to solve the problem of LED heat dissipation. However, for garden lights, such a model "wind and rain" has a poor function and is not suitable for solar garden lights.

     Although the solar garden lamp market is developing rapidly under the support of the government, it cannot be ignored that the long-term development of the solar garden lamp market still faces serious challenges. At present, in addition to the high cost, the main problems faced by solar garden light products include: light source, heat dissipation and power system.

     From the perspective of the light source, on the one hand, it is necessary to further improve the luminous efficiency of the LED, and on the other hand, to improve the arrangement of the light source. At present, a large part of the garden lamp manufacturer in the garden lamp manufacturer is arranged by a lattice structure. The advantage of this method is that it is beneficial to solve the heat dissipation problem, but because of the insufficient lateral illumination distance of the structure, The distribution range of the light source is large, which leads to the inability to achieve centralized light distribution and the need to use the secondary lens to achieve independent light distribution. This requires high selection of secondary lenses. At present, secondary lenses of different materials have certain problems, affecting The effect of the product. If the treatment is not good, the use of the lens will also affect the lighting effect and clarity of the road surface.

     In order to improve the above problems, some solar garden lamp companies have already introduced a light source using an integrated module method, which reduces the lack of light of one or several products that occur when the finished product is in operation due to the arrangement of the light source. In addition, since the concentrated light distribution can be realized by the reflector, the negative influence caused by the use of the secondary lens can also be avoided. However, it is undeniable that the light source in this package will face more severe heat dissipation challenges. From the perspective of power supply, unlike traditional lighting products, which can be directly connected to AC mains, LEDs are low-voltage driving devices and require constant current driving, which requires redesigning the power system of solar garden lights. At present, the cost accounts for about 10%-20% of the total, and the power system will not affect the service life of the product to a large extent.

     Application promotion is also the reason for hindering the development of solar garden lights. Since there are no formal standard specifications for solar garden lights, several main parameters such as color temperature and glare have not yet been determined, and solar garden lights cannot be fully promoted. Secondly, the high price of solar garden lights also brings great difficulties to the promotion and application of LED street lamps. In addition, the lighting standards of solar garden lights and the road pavement test using solar garden lights have not yet been formulated. At this stage, the development of the solar garden light market is mainly dependent on the government's strong support.
