Abstract

The utility model provides an LED (light-emitting diode) lamp provided with a plastic casing having multiple layers of thermal convection holes. The LED lamp comprises an LED light-emitting board, a lampshade, a lamp holder, a driving power supply and a plastic housing, wherein the plastic housing is located behind the lampshade; the lampshade is connected with the front end of the plastic casing; the LED light-emitting board is connected with the plastic casing; the lamp holder is connected with the rear end of the plastic casing; a plurality of layers of heat radiation holes are formed on the plastic casing; a plurality of heat radiation holes are formed on every layer; and an aluminum heat radiator is mounted in a space surrounded by the plastic casing. The LED lamp provided by the utility model makes the traditional LED lamps even better, particularly, the surface of the LED lamp adopts the plastic as the casing, so that the insulating property of the LED lamp is excellent; the safe aluminum heat radiator is adopted as the internal core of the LED lamp, so that the manufacturing cost becomes lower; and the multiple layers of heat radiation holes can further assist the thermal convection, so that the heat radiation of the LED lamp can achieve satisfactory results.

Description

A kind of have a LED lamp that shell is moulded in multilayer heat loss through convection hole

Technical field

The utility model relates to a kind of LED electricity-saving lamp, belongs to LED and makes the field.

Background technology

Advocate in country under the situation of low-carbon economy, the LED electricity-saving lamp is with its longevity (3-5 hour), more energy-conservation (every watt of 60-100) single unique advantages, and is flourish in illuminating industry.Existing in the market style various in style, most structure is: top is that lampshade, middle part are aluminium matter heat radiation foundry goods, and the LED luminous plaque is fixed on the heat radiation aluminum component, and aluminum component inside is driving power, and the bottom is a lamp holder.The LED lamp of this structure, it is bigger with the aluminium amount, and outside aluminium matter heat radiation foundry goods was directly exposed to, as the electricity consumption product, what security means no matter metal exposed taked outside, and hidden danger is still arranged after all.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of LED lamp that shell is moulded in multilayer heat loss through convection hole that has, and its cost is low, safer.For this reason, the utility model is by the following technical solutions: it comprises LED luminous plaque, lampshade, lamp holder, driving power, described driving power is connected with lamp holder, described LED luminous plaque is connected with driving power, described LED lamp also comprises the described shell of moulding, describedly mould the rear that shell is in lampshade, described lampshade is connected with the front end of moulding shell, described LED luminous plaque with mould shell and be connected, described lamp holder is connected with the rear end of moulding shell, described moulding offers described multilayer heat loss through convection hole on the shell, every layer is provided with a plurality of louvres, and described moulding in the space that shell surrounds also is provided with aluminium radiator.

Because adopt the technical solution of the utility model, the utility model LED lamp is that the kind of existing LED lamp is made something perfect even more perfect, provide a kind of with plastic casing and have the LED lamp in multilayer heat loss through convection hole.Shell is done with plastics in its surface, makes LED lamp insulation fine, and safer aluminium radiator becomes the inner core of LED lamp, and manufacturing cost is lower, and multilayer heat loss through convection hole can also help to realize heat loss through convection, guarantees that the heat radiation of LED lamp obtains promising result.

The specific embodiment

Embodiment 1, with reference to Fig. 1,2,3.

With reference to accompanying drawing.The utility model comprises LED luminous plaque 2, lampshade 1, lamp holder 8, driving power 7, described driving power 7 is connected with lamp holder 8, described LED luminous plaque 2 is connected with driving power 7 usefulness leads, described LED lamp also comprises the described shell 6 of moulding, describedly mould the rear that shell 6 is in lampshade 1, described lampshade 1 is connected with the front end of moulding shell 6, described LED luminous plaque 2 is connected with the front end of moulding shell 6 by screw 3, described lamp holder 8 is connected with the rear end of moulding shell 6, described moulding offers described multilayer louvre 60 on the shell 6, every layer is provided with a plurality of louvres 60, and described moulding in the space that shell surrounds also is provided with aluminium radiator 5.

The described outer peripheral face of moulding shell is provided with the wing plate 61 of radial arrangement.As shown in Figure 1, the outer shape of described wing plate 61 is connected mutually with described lampshade 1.Described wing plate 61 can play moulding shell 6 and being in the protective effect of the louvre 60 in the wing plate zone and helping heat radiation.

As shown in Figure 1, 2, 3, the described shell of moulding is and has 2 layers or 2 layers of ladder cylindrical shell to top bar.Described louvre 60 is opened on the step surface 62 of ladder cylindrical shell, and under most of user modes, this hole forms the duct of vertical direction, more helps to form heat loss through convection.Aluminium radiator 5 also can be stepped.

Described aluminium radiator 5 is close to by thermal conductive silicon glue-line 4 with LED luminous plaque 2 and is connected, and is between LED luminous plaque 2 and the driving power 7.

The described front end of moulding shell is provided with annular mounting groove 63, and described lampshade 1 is inserted in the described annular mounting groove 63 and with glue and glues post, and described LED luminous plaque is supported on the internal groove side wall 64 of annular mounting groove.

When LED etc. lights, by LED luminous plaque 2(aluminium base) heat that produces, conduct to aluminium radiator 5 by heat conductive silica gel, the heat of aluminium radiator 5 distributes at it and moulds in the space between the shell 6, mould and offer multilayer louvre 60 on the shell 6, the heat that makes aluminium radiator 5 and mould 6 on shell constantly flows out from louvre 60, thereby reaches the effect of heat radiation.
