Abstract
The utility model relates to a LED lamp for refrigerator, comprising a lamp holder and a LED lamp. A round groove and a knob hole which are communicated are arranged on the front of the lamp holder, and the back of the lamp holder is provided with a control circuit board seat for holding a circuit board in which a temperature controller groove for a temperature controller is arranged. A knob of a temperature controller is arranged in the knob hole and is connected to the temperature controller, and the bottom of the round groove is provided with clamping holes to which a lampshade is clamped and connected. One end of the LED lamp passes through the round groove and is exposed in the outside, and the other end is connected by electricity to the control circuit board which is connected to the power by a conductor. The beneficial effect of the utility model is as follows: the temperature controller groove and the structures of the knob holes can organically combine the temperature controller and the LED lamp, small in volume and convenient in utilization.
Description
Technical field
The utility model relates to a kind of illuminating lamp, especially a kind of refrigerator LED illuminating lamp.
Background technology
Present structure of the lighting lamp is fairly simple, and bulb is fixed in the lamp socket and is connected with power supply; Its deficiency is: temperature controller is mounted in different positions with lamp socket, and volume is big and use inconvenience, and the brightness of bulb is lower and service life short.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, and a kind of refrigerator LED illuminating lamp is provided.
The utility model solves the technical scheme that its technical problem adopts: this refrigerator LED illuminating lamp, comprise lamp socket and LED lamp, the front of described lamp socket has circular groove and the knob hole that interconnects, the reverse side of lamp socket is provided with the circuit panel seat of placing control circuit board, the temperature controller groove of placing temperature controller is arranged in the circuit panel seat, the temperature controller knob is placed in the knob hole and is connected with temperature controller, and the circular groove bottom has with lampshade and is the hole clipping that clamping cooperates; LED lamp one end passes outside circular groove is exposed to, and the other end and control circuit board are electrically connected, and control circuit board is connected with power supply by lead.
On the described lamp socket switch is arranged.
Have the knob groove that is used to place temperature controller knob connecting rod on the described circuit panel seat.
Described circuit panel seat takes the shape of the letter U, and forms the temperature controller groove in it.
Be fixedly connected with cover plate on the described circuit panel seat.
Be provided with a boss in the described circular groove, the LED lamp is distributed on around the boss.
The effect that the utility model is useful is: owing to adopted the structure of temperature controller groove and knob hole in the lamp socket, organically temperature controller and LED lamp are combined, volume is little and easy to use.

Description of reference numerals: lamp socket 1, temperature controller groove 1-1, circular groove 1-2, boss 1-3, knob groove 1-4, knob hole 1-5, circuit panel seat 1-6, LED lamp 2, lead 3, switch 4, temperature controller knob 5, control circuit board 6, cover plate 7, hole clipping 8, lampshade 9.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1-Figure 3, this refrigerator LED illuminating lamp, comprise lamp socket 1 and LED lamp 2, the front of described lamp socket 1 has circular groove 1-2 and the knob hole 1-5 that interconnects, the reverse side of lamp socket 1 is provided with the circuit panel seat 1-6 that places control circuit board 6, switch 4 is arranged on the lamp socket 1, be provided with a boss 1-3 among the circular groove 1-2, LED lamp 2 is distributed on around the boss 1-3.Described circuit panel seat 1-6 takes the shape of the letter U, and forms temperature controller groove 1-1 in it, is fixedly connected with cover plate 7 on the circuit panel seat 1-6.Temperature controller groove 1-1 that places temperature controller and the knob groove 1-4 that places temperature controller knob 5 connecting rods are arranged in the circuit panel seat 1-6, temperature controller knob 5 is placed among the knob hole 1-5 and is connected with temperature controller, and circular groove 1-2 bottom has with lampshade 9 and is the hole clipping 8 that clamping cooperates; LED lamp 2 one ends pass outside circular groove 1-2 is exposed to, and the other end and control circuit board 6 are electrically connected, and control circuit board 6 is connected with power supply by lead 3.
As shown in Figure 4, the drive circuit in this control circuit board drives great power LED in the dc lighting system, and 95% efficient, longer service life can be provided, and can bear higher electric and mechanical shock.ZXSC300 series DC-DC controller drives the external switch with decompression mode work.Can provide higher system voltage by the value that increases R2, for example, the voltage that obtain 24V only needs to change the R2 value into 2.2k Ω, and capacitor C 1 also must have higher rated voltage simultaneously, the circuit basic functional principle is as follows: when the Q1 conducting, electric current flows through LED, capacitor C 2 and inductance.Pressure drop when the R1 two ends reaches I
SenseDuring the threshold voltage of pin, Q1 turn-offs also and keeps a set time, and the energy in the inductance flows through D1 and LED.Through after this set time, Q1 is conducting again, so moves in circles.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
