Lamp

Abstract

The invention discloses a lamp, which comprises a lamp holder, a lamp cover and a lamp body, wherein the lamp body comprises a lamp cup; two opposite ends of the lamp cup are connected with the lamp holder and the lamp cover respectively; a plurality of radiating fins are arranged on periphery of the lamp cup; a light source module is disposed at one end of the lamp cup, which is close to the lamp cover; the lamp cover covers the light source module; the lamp body further comprises a protective device which is arranged on the periphery of the lamp cup; the protective device encloses the radiating fins; a plurality of through holes are formed on the protective device; and the through holes are communicated with channels among the radiating fins. The protective device presents a corresponding appearance according to the shape of a radiating part, thus protecting the radiating part in a fixed manner and preventing the radiating fins from being scratched; and meanwhile, the whole beautiful figure of the lamp is improved.

Description

technical field [0001] The invention relates to a lighting device, in particular to a lamp. Background technique [0002] Since Light Emitting Diode (LED) has the advantages of long life, high luminous efficiency, small size, and low pollution, it has been increasingly used as an ideal light source in recent years and widely used in various lamps. A traditional lamp includes a lamp cup, a light-emitting diode module accommodated in the lamp cup, and a lampshade fixed on the lamp cup and covering the light-emitting diode module. [0003] As LED lights tend to be characterized by high luminescence, high brightness, light weight and miniaturization, the problems of high heat and internal space are becoming more and more serious. For heat dissipation, the main problem is to dissipate heat quickly and effectively. Therefore, it is necessary to add a sufficient number of heat sinks in a limited space, but often the more the number of heat sinks, the thinner the thickness will be,...

Problems solved by technology

[0003] As LED lights tend to be characterized by high luminescence, high brightness, lightness and miniaturization, the problems of high heat and internal space are becoming more and more serious. For heat dissipation, the main problem is to dissipate heat quickly and effectively. Therefore, it is necessary to add a sufficient number of heat sinks in a limited space, but often the more the number of heat sinks, the thinner the thickness will be, which will cause the heat sink to deform more easily, and the heat dissipation effect and appearance of the lamp will be affected.

In addition, the heat sink is too thin, and its sharp edges are likely to cause injury to users, so users need to bear greater risks when using
