Example 1:

as shown in fig. 1 and 2: a lamp comprises a shell 1, a capacitor 2, a luminous body 3, two connecting pieces 4, a first electric connection part 5 and a second electric connection part 6, wherein one end of each connecting piece 4 is connected with the first electric connection part 5, the other end of each connecting piece is connected with the second electric connection part 6, and the second electric connection part 6 is further electrically connected with the luminous body 3; the connecting piece 4 is made of molybdenum.

The wrapping layer is a high-temperature-resistant nonmetal wrapping layer, specifically can adopt a silica gel wrapping layer, a ceramic wrapping layer, a glass wrapping layer, a crystal wrapping layer, an asbestos wrapping layer or a cement wrapping layer, and is not limited to the exemplified materials.

The wrapping layer 2-1 has the following functions: high temperature isolation in the production process prevents the electrolytic capacitor from being damaged. The general electrolytic capacitor can bear the time that 265 ℃ does not exceed 10S, and 400 ℃ does not exceed 3S; in the production process of G9G 4 or other similar products, the softening temperature of the glass is very high, so that the performance of the electrolytic capacitor is affected when the glass is softened, and the electrolytic capacitor is damaged. After the wrapping layer is added, the rejection rate is reduced, the service life of the product is ensured, the reliability of the product is improved, the requirement on the process fineness is relatively reduced, and the production and popularization are facilitated.

Further, the wrapping layer 2-1 includes an open end, and the open end is located at the pin position end of the capacitor 2. Such a design is relatively simple to implement in terms of process, and if the production process allows, the function can also be achieved by providing the casing as a sealed or semi-sealed structure, with the pins protruding from the sealed or semi-sealed casing. The sealing structure can be realized by arranging a colloid sealing layer at the opening end.

The fluorescent layers comprise a first fluorescent layer and a second fluorescent layer, the second fluorescent layer is positioned outside the power supply access point and the capacitor access point, and the first fluorescent layer is positioned at other parts of the luminous body, namely outside the light-emitting diode;

because the power supply access point and the capacitor access point are exposed outside, obvious contact structures can be seen from the shell, fluorescent layers, namely common fluorescent colloid layers, are arranged outside the power supply access point and the capacitor access point, and the product structure is attractive. And the first fluorescent layer and the second fluorescent layer have the same color. In other embodiments, the first phosphor layer and the second phosphor layer may be of similar or completely different colors.

Furthermore, the fluorescent layer comprises heat dissipation materials, and as the light emitting diode, the power supply access point and the capacitance access point are heating parts, the heat dissipation materials are doped in the light emitting layer, so that heat can be effectively dissipated.

Further, the base plate both sides all set up emitting diode, the base plate is equipped with the conducting hole, and the setting of conducting hole and two sides emitting diode is in order to realize all-round illumination to and the illumination of different angles is even.

Because the outside of the power supply access point is exposed, an obvious contact structure can be seen from the shell, and the power supply access point is not attractive, and therefore, a fluorescent layer, namely a commonly used fluorescent colloid layer, is also arranged outside the power supply access point, so that the product structure is attractive.

Furthermore, the fluorescent layer comprises heat dissipation materials, and because the light-emitting diode and the power supply access point are heating parts, the heat dissipation materials are doped in the light-emitting layer, so that heat can be effectively dissipated.
