Description

A kind of LED spotlight

technical field

The utility model relates to a lighting lamp, in particular to an LED spotlight.

Background technique

In recent years, LED lights have achieved rapid development and are gradually entering the field of general lighting. Compared with traditional incandescent tungsten bulbs and fluorescent lamps, LED bulbs have the advantages of small size, low temperature, and low power consumption, and can be started at low voltage and low current, fast ignition speed and high-frequency operation, and long service life. At present, the spotlights used in the home office field are mainly metal halide quartz lamps. This kind of spotlight emits light after the filament heats up. The luminous efficiency is low and the heat is extremely high, resulting in a short life.

Utility model content

The purpose of the utility model is to provide an LED spotlight with higher luminous efficiency and heat dissipation performance.

The technical scheme adopted by the utility model to solve the technical problem is: an LED spotlight, including a lamp cap, a lampshade and pins, a light-transmitting plate is arranged at the front end of the lampshade, a reflector is arranged inside the lampshade, and an LED light-emitting diode is arranged at the bottom of the reflector and the circuit assembly, a heat-conducting silicone layer is provided between the lampshade and the reflector cup, and a heat-conducting groove is longitudinally provided on the outer surface of the lampshade.

Wherein, the inner surface of the reflective cup is uniformly provided with a plurality of bumps, and the bumps are provided with a reflective coating.

The beneficial effect of the utility model is: the heat-conducting silica gel layer between the lampshade and the reflective cup can transfer the heat generated by the LED light-emitting diode to the lampshade in time, and the heat-conducting groove outside the lampshade further dissipates the heat into the air, and the heat dissipation effect is excellent. Compared with traditional spotlights, it has higher luminous efficiency and heat dissipation performance.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Referring to Figure 1, an LED spotlight includes a lamp cap 1, a lampshade 2 and pins 3, a light-transmitting plate 9 is provided at the front end of the lampshade 2, and a reflector 6 is arranged inside the lampshade 2, and the inner surface of the reflector 6 is uniform. There are a plurality of bumps, the bumps are provided with a reflective coating, the bottom of the reflective cup 6 is provided with LED light-emitting diodes 4 and circuit components 5, a heat-conducting silica gel layer 7 is provided between the lampshade 2 and the reflective cup 6, and the outer surface of the lampshade 2 A heat-conducting groove 8 is longitudinally arranged, and the heat-conducting silica gel layer 7 between the lampshade 2 and the reflector cup 6 of the utility model can transfer the heat generated by the LED light-emitting diode 4 to the lampshade 2 in time, and the heat-conducting groove 8 outside the lampshade 2 further dissipates the heat to In the air, the heat dissipation effect is excellent, and it has higher luminous efficiency and heat dissipation performance than traditional quartz spotlights.

What is described above is only the preferred embodiment of the present utility model, and it should be pointed out that for those of ordinary skill in the art, without departing from the premise of the inventive concept of the present invention, some deformations and improvements can also be made, and these all belong to Protection scope of the present utility model.
