Abstract

The utility model relates to the technical field of LED lamps and the application thereof, particularly to an LED underground spot lamp, which comprises a lamp holder, a face plate, light-transmitting glass, an LED substrate and LEP lamps. The lamp holder comprises a lamp holder upper part and a lamp holder lower part, the lamp holder upper part has an inwardly concave surface, a plurality of LED lamp holes are arranged on the inwardly concave surface, and the LED lamps pass through the LED lamp holes to be installed on the LED substrate. The LED underground spot lamp also comprises a heat radiator installed inside the lower part of the lamp holder, and the LED substrate is fixed between the upper part of the lamp holder and the heat radiator in a contact way. The LED underground spot lamp has the advantages of simple structure, convenient installation and lower manufacturing cost; and the good heat radiation effect of the LED underground spot lamp ensures that the LED lamp operates at a normal environmental temperature and is helpful for prolonging the service life of the LED.

Description

The buried shot-light of a kind of LED

Technical field:

The utility model relates to LED lamp and applied technical field thereof, refers in particular to the buried shot-light of a kind of LED.

Background technology:

Buried shot-light is to be embedded in underground light fixture, and it is widely used in the usefulness as illumination and decoration such as buildings such as shopping centre, square, park, trees, theater, each tourist attractions, large-scale statue, beautifies the environment, and adds new meaning to people's life.

Because the special use occasion of buried shot-light, therefore require it to have very high brightness usually, the buried shot-light that generally adopts is generally metal halide lamp or fluorescent lamp at present, the buried shot-light power of this class height, power consumption are big, and caloric value is also high, cause fluorescent tube short service life, and light is dazzling, we can say neither energy-conservation also not environmental protection.

LED more and more is widely used as light source, and is not dazzling because its luminous efficiency height, low in energy consumption be a kind of energy-saving light fixture, and its light is soft, is the environment-friendly type light source.Therefore LED also has application corresponding on buried shot-light.Yet reach the needed brightness of buried shot-light, also to use high-power LED as light source, and the more common LED caloric value of great power LED wants big certainly, therefore also need it is done necessary radiating treatment, otherwise cause the LED operating ambient temperature too high easily, LED is shortened service life greatly.The existing buried shot-light complex structure of LED with heat radiation, the cost height is unfavorable for the promotion and application of the buried shot-light of LED.

The utility model content:

The purpose of this utility model is to overcome the above-mentioned weak point of prior art, and a kind of LED simple in structure, easy for installation is provided buried shot-light.

The technical solution adopted in the utility model is: the buried shot-light of LED, comprise lamp socket, panel, transparent glass, LED substrate and LED lamp, wherein: described lamp socket comprises lamp socket top and lamp socket bottom, described lamp socket top has an inner concave, and this inner concave offers some LED lamp holes, and described LED lamp passes described LED lamp hole and is installed on described LED substrate; It also comprises a radiator, and described radiator is installed in the lamp socket bottom, and described LED substrate contacts is fixed between described lamp socket top and the described radiator.

Particularly, the inner surface of described lamp socket bottom is the frustum cone side shape, and the outer surface of described radiator shape with it matches, and this structure makes radiator can be positioned suitable position in the lamp socket easily, simplifies the installation of radiator.

The inboard of the raised edges on described lamp socket top forms a scrobicular ring, and described transparent glass is installed between described panel and the lamp socket top by this scrobicular ring and forms sealing.The degree of depth of described scrobicular ring need guarantee that the lower surface of transparent glass does not contact with the LED lamp, in order to avoid damage the LED lamp by pressure.

The outside of described lamp socket bottom forms an inner fovea part, and in this inner fovea part place be provided with the lamp socket bottom in the water joint that is connected, be used to connect power line, the structure of indent also makes the volume of the buried shot-light of integral LED littler, compacter.

The buried shot-light of the utility model LED is simple in structure, installs easily, and cost of manufacture is lower, and the buried shot-light of LED has better heat radiating effect, guarantees that the LED lamp works under normal environment temperature, helps prolonging the service life of LED.

Description of drawings:

Fig. 1 is a stereogram of the present utility model;

Fig. 2 is a sectional structure schematic diagram of the present utility model.

The specific embodiment:

Below in conjunction with specific embodiments and the drawings the utility model is further specified.

As shown in Figure 1, 2, the buried shot-light of the utility model LED mainly comprises lamp socket 1, panel 2, transparent glass 3, LED substrate 4 and LED lamp 5, and wherein lamp socket 1 comprises lamp socket top 11 and lamp socket bottom 12, and the two can be by being threaded or other modes connect.

At first please see lamp socket top 11; its middle part forms an inner concave 110; the corresponding edge is a projection; form a scrobicular ring 113 in the inboard of raised edges; the external diameter of the internal diameter of this scrobicular ring 113 and transparent glass 3 is suitable, so transparent glass 3 is installed on this scrobicular ring 113, then panel 2 by bolted in the raised edges on described lamp socket top 11 and transparent glass 3 is fixing; before fixing, article such as sealing ring, colloid can be passed through at interior ring 113 places, to guarantee to obtain good sealing effectiveness.

On the inner concave 110 on lamp socket top 11, evenly offer 3 LED lamp holes 111 so that LED lamp 5 passes in the space between inner concave 110 and transparent glass 3.Below inner concave 110, LED substrate 4 and radiator 6 are installed successively, and 4 contacts of described LED substrate are fixed between described lamp socket top 11 and the described radiator 6.

The inner surface of described lamp socket bottom 12 is the frustum cone side shape, and the outer surface of described radiator 6 shape with it matches, and does not therefore need other parts or equipment radiator 6 stable being installed in the lamp socket bottom 12 greatly can be simplified installation procedure.

The outside of described lamp socket bottom 12 forms an inner fovea part 121, and in these inner fovea part 121 places be provided with lamp socket bottom 12 in the water joint 7 that is connected, this water joint 7 is used to connect power line.

In sum, the buried shot-light of the utility model LED is simple in structure, installs easily, and cost of manufacture is lower, and the buried shot-light of LED has better heat radiating effect, guarantees that the LED lamp works under normal environment temperature, helps prolonging the service life of LED.
