preparation example Construction

[0027] The preparation method of above-mentioned heat dissipation coating of the present invention is:

[0028] (1) Weigh each component of the formula ratio, then first add the carbon nanotubes into ethylene glycol at a temperature of 50-80°C, and stir evenly;

[0029] (2) Then the inorganic colloidal particles are added to the mixed system of epoxy resin and methyl methacrylate and stirred evenly;

[0030] Mix the solution of step (1) and step (2), then add spinel after electronic transition, rare earth element oxide and stabilizer and stir evenly to obtain the heat dissipation coating, and mechanically spray the above coating on the The upper and lower surfaces of the aluminum plate are provided with a heat dissipation coating.

Embodiment 1

[0031] Embodiment 1: 15 parts of inorganic colloid particles, 2.5 parts of carbon nanotubes, spinel (LiMn 2 o 4 Spinel) 40 parts, 0.05 parts of cerium oxide, 0.3 parts of kerosene, 3 parts of epoxy resin, 10 parts of methyl methacrylate, 3 parts of ethylene glycol. The above-mentioned heat dissipation coating was applied to the upper and lower surfaces of the aluminum plate with a mechanical spray gun to obtain a heat sink, and the data obtained by testing the heat sink are shown in Table 1:

[0032] Table 1. Heat sink performance testing parameter list

[0033]

[0034] The heat sink 9 is glued in the gap and sealed by the sealant. This structure is used to seal the cavity to prevent water from entering the cavity.

Abstract

The invention provides a high-radiating-performance combined type LED street lamp which comprises an upper shell and a lower shell. The two ends of the upper shell and the two ends of the lower shell are connected through two side plates to form a cavity for containing a plurality of LED modules, each side plate is provided with a plurality of gaps communicated with the cavity, each gap is provided with a radiating fin, and each radiating fin is an aluminum plate respectively coated with a radiating coating on the upper surface and the lower surface. Each radiating coating is made of, by weight, 8 parts to 25 parts of inorganic gel particles, 2.5 parts to 5 parts of carbon nanotubes, 20 parts to 60 parts of spinelle after electron transition, 0.05 part to 2 parts of rare earth element oxides, 0.1 part to 0.3 part of stabilizers, 3 parts to 10 parts of epoxy resin, 3 parts to 10 parts of methyl methacrylate and 2 parts to 5 parts of ethylene glycol. According to the adopted combined LED street lamp, the heat radiating speed is high, and the LED modules are not prone to heating.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to a high heat dissipation combined LED street lamp. Background technique [0002] LED street lamps in the prior art are generally installed on roadside light poles, and generally include two parts: an LED light source module and a power supply. At present, there is a combined LED street lamp, which is provided with a cavity for accommodating LED modules, and the LED modules are assembled in the cavity. Since the cavity is sealed, it is difficult for the heat emitted by the LED module to dissipate from the cavity. As a result, the LED module is prone to heat, and the entire combined LED street lamp fails. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art, and provide a combined LED street lamp in which the heat is dissipated quickly and the LED module is not easy to generate heat.
