Abstract

The utility model discloses an LED lamp which comprises a main plastic casing and a metal heat-radiating module. The metal heat-radiating module comprises a substrate and a heat-radiating fin plate, wherein a light-emitting chip is installed on one side of the metal heat-radiating module away from the heat-radiating fin plate, the heat-radiating fin plate and the main plastic casing are integrally formed through pouring, the edge of the substrate of the metal heat-radiating module is embedded into the main plastic casing, and the upper and lower sides of the metal heat-radiating module are exposed in a larger-area mode. In the LED lamp, the metal heat-radiating module can be used for the light-emitting chip to be installed and performed heat radiation on the heat-intensive chip portion, and the other portions where heat is little can be made of plastics. In addition, the main plastic casing and the metal heat-radiating module is integrally formed through pouring, the structural firmness is good, and what's more important is that a larger amount of metal materials are saved, and good heat-radiating effect is kept.

Description

LED light fixture

Technical field

The utility model relates to a kind of LED light fixture.

Background technology

The housing entirety of tradition LED light fixture adopts metal to make, although good heat dispersion performance, its material cost is high, and weight is large, and manufactures inconvenience.

Summary of the invention

In view of the deficiency of background technology, technical problem to be solved in the utility model is to provide a kind of LED light fixture that can keep better heat dispersion in significantly reducing costs.

For this reason, a kind of LED light fixture that the utility model provides, comprise plastics main casing and heat dissipation metal module, heat dissipation metal module comprises substrate and radiating fin plate, luminescence chip is installed on the side of heat dissipation metal module away from radiating fin plate, described heat dissipation metal module and plastics main casing are poured into a mould one mutually, and the substrate edges of heat dissipation metal module is embedded in plastics main casing, and the upper and lower both sides of described heat dissipation metal module large area is exposed.

In the utility model, the housing of LED light fixture adopts plastics main casing and heat dissipation metal module composition, in heat dissipation metal module, can be used for installing luminescence chip, can divide and form heat radiation the concentrated chip section of generating heat, and other few parts of generating heat just can be adopted made of plastic, and the firmness of plastics main casing and heat dissipation metal module cast integrative-structure is also better, the most important thing is to save a large amount of metal materials, and has kept good radiating effect.

Detailed description of the invention

As shown in Figure 1, Figure 2, Figure 3 shows, the LED light fixture that the utility model provides, comprise plastics main casing 1 and heat dissipation metal module 2, heat dissipation metal module 2 comprises substrate 3 and radiating fin plate 4, luminescence chip is installed on the side of heat dissipation metal module 2 away from radiating fin plate 4, described heat dissipation metal module 2 and plastics main casing 1 cast one mutually, substrate 3 edges of heat dissipation metal module 2 are embedded in plastics main casing 1, described heat dissipation metal module Shang Xia 2 both sides large area exposed.

As shown in Figure 5, on the basis of above-described embodiment, on radiating fin plate 4, be densely covered with along its length the elongated raised line 5 being parallel to each other.Elongated raised line 5 on radiating fin plate 4 can increase the area of dissipation of radiating fin plate 4, and can promote to ventilate, and is conducive to heat radiation.

As shown in Figure 4, in the above-described embodiments, in order to make the profile of LED light fixture more attractive in appearance, the corresponding radiating fin plate 4 in described plastics main casing 1 back side is distributed with plastics wing plate 6.The existence of plastics wing plate 6 can make the radiating fin plate 4 at LED light fixture back can not have suddenly at two side positions, but has been substituted the wing plate of traditional metal material by plastics wing plate 6, makes its maintenance consistent with the profile of traditional LED light fixture, thereby more attractive in appearance.
