Description

technical field [0001] The invention relates to the technical field of LED lighting fixtures, in particular to an LED bulb lamp. Background technique [0002] Regarding the materials and processing technology of LED bulb lamps, the current methods used in the lighting industry are as follows: [0003] (1) General plastics: Plastic injection molding process is used, but the heat dissipation effect of general plastic materials is extremely poor; [0004] (2) Thermally conductive plastic: using plastic injection molding process, the heat dissipation effect of thermally conductive plastic is slightly better than that of ordinary plastic materials. However, the product development of thermally conductive plastic in the market has not yet been diversified, so this material is still a high-priced material; [0005] (3) Aluminum alloy: using die-casting technology, the aluminum alloy material must go through various post-processing procedures before it can be accepted by the market...

AI Technical Summary

Problems solved by technology

[0003] (1) General plastics: Plastic injection molding process is used, but the heat dissipation effect of general plastic materials is extremely poor;

[0004] (2) Thermally conductive plastic: using plastic injection molding process, the heat dissipation effect of thermally conductive plastic is slightly better than that of ordinary plastic materials. However, the product development of thermally conductive plastic in the market has not yet been diversified, so this material is still a high-priced material;

Due to the cumbersome processing technology and indirectly increased costs, the unit price of the product is relatively high; only a few aluminum materials suitable for die-casting are available in the market; The surface needs to be painted or electroplated to greatly reduce the heat dissipation effect;

[0006] (4) Aluminum profile: use aluminum extrusion or aluminum pumping process, the material of aluminum profile must undergo secondary post-processing procedures, and use milling process to process it into the shape effect required by the market, so the unit price of aluminum profile products is high, so that Increased manufacturing costs

[0007] Due to the limited internal space of the lamp, if the high heat generated by the LED light cannot be effectively exported to the outside for heat dissipation, the heat energy will be accumulated inside the product, resulting in a decrease in the lumens of the LED light source, premature light decay or shortened service life, etc.

[0008] According to the above description, it can be seen that materials that are cheap, fast and easy to use, such as general plastics and heat-conducting plastics, are only suitable for low-wattage lamps; on the contrary, metal materials with good heat conductivity, such as aluminum alloy and aluminum profiles , but the high unit price due to too many manufacturing processes and slow manufacturing speed makes it difficult for the lamps manufactured with it to meet the needs of consumers
