Description

A kind of LED lamp

technical field

The invention relates to a street lamp, in particular to an LED lamp.

Background technique

Zhonghua lamp is a kind of lighting equipment used in public facilities such as main roads, parks and squares in the city. Usually, a spherical lamp is installed on the top of the lamp pole, which is beautiful and generous.

However, the lampshade of the traditional Chinese lamp is a closed sphere. The light emitted by the built-in light source is reflected by the inner coating of the lampshade for many times, so that the light transmitted from the lampshade is greatly reduced, the light efficiency is low, and the illuminance of the illuminated road is very low. low, and some even cannot meet the required value of road illumination given by the national standard, and need to install a light source with a larger wattage, resulting in a great waste of energy.

Contents of the invention

In order to overcome the deficiencies of the prior art, the invention provides a Chinese lamp with high illuminance and energy saving.

The technical solution adopted by the present invention to solve its technical problems is:

An LED lamp, comprising a lamp holder and a lampshade arranged on the lamp holder, a first heat sink and a first light source module are arranged inside the lamp holder, and the feature is that several light source modules are arranged on the outer wall of the lamp holder .

The lamp holder is provided with a power supply box and a connecting plate, and the power supply box is fixed in the lamp holder through the connecting plate, the first heat sink is arranged on the connecting plate, and a connecting piece is arranged on the first heat sink. A light source module is disposed on the connecting piece.

The light source modules are evenly distributed around the outer wall of the lamp holder.

The light source module includes a second light source module, a second heat sink and a lamp housing installed on the second heat sink, and the second light source module is arranged on the second heat sink.

Radiating fins are arranged on the second radiator.

The first light source module includes a first LED chip and a first circuit board.

The second light source module includes a second LED chip and a second circuit board.

The beneficial effects of the present invention are: the present invention discloses an LED lamp, comprising a lamp holder and a lampshade arranged on the lamp holder, a first heat sink and a first light source module are arranged in the lamp holder, and the feature is that the lamp There are several light source modules on the outer wall of the lamp holder, through which several low-power light source modules are added to the outer wall of the lamp holder to directly illuminate the road surface, which improves the utilization rate of light, greatly reduces the loss of light, and thus reduces the The lighting power of the first light source module in the spherical lampshade is improved, which not only meets the required value of road surface illuminance of the national standard, but also saves energy.

Detailed ways

The idea, specific structure and technical effects of the present invention will be clearly and completely described below in conjunction with the embodiments and accompanying drawings, so as to fully understand the purpose, features and effects of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative efforts belong to The protection scope of the present invention.

Referring to Fig. 1 to Fig. 3, the present invention discloses an LED lamp, which includes a lamp holder 1 and a lampshade 2 arranged on the lamp holder 1, and a first radiator 4 and a first light source module (not shown in the figure) are arranged in the lamp holder. shown), several light source modules 9 are provided on the outer wall of the lamp holder. In this specific example, the lamp holder 1 is provided with a power supply box 3 and a connection plate 5, and the power supply box 3 is fixed to the lamp through the connection plate 5 In the tray 1, the first radiator 4 is arranged on the connecting plate 5, the first radiator 4 is provided with a connecting piece 6, the first light source module is arranged on the connecting piece 6, and the power supply is an external power supply. The power supply box 3 is only provided with some plug connectors, and the power supply of the first light source module is realized by connecting the external power supply through the plug connectors in the power supply box 3. In addition, there is an inner protective cover between the lamp holder 1 and the lampshade 2 7. The lampshade 2 is fixed on the lamp holder 1 through the inner protective cover 7.

As shown in the figure, the eight light source modules 9 are evenly distributed around the outer wall of the lamp holder 1, so that the light emitted by the light source modules 9 can evenly illuminate the ground around the street lamp. In this specific embodiment, the specific structure of the light source module 9 is that the light source module 9 includes a second light source module 10, a second heat sink 11 and a lamp housing 12 installed on the second heat sink 11, the second light source module 10 is set on the second radiator 11, and the second radiator 11 is installed on the lamp holder 1 by screws, so that the light source module 9 is fixed on the lamp holder 1, and the lamp housing 12 and the second radiator 11 are made into flower petals Or the shape of the blade, which is more beautiful.
