## Abstract

A LED lamp includes housing, a circuit layer, at least one LED die, a light-transmitting adhesive, a lamp shade, a light-transmitting liquid and the conductive connector. One end of the housing has a protrusion. The circuit layer is placed on the protrusion. The LED die is placed on the protrusion and electrically connected to the circuit layer. The light-transmitting adhesive covers the circuit layer and the light emitting die. The lamp shade including a plurality of ventilating holes is connected to the housing, and an accommodating space is cooperatively defined by the lamp shade and the housing. The light-transmitting liquid is filled within the accommodating space, and the LED die is sunk therein.

## Claims

### Claim 1

A light emitting diode (LED) lamp comprising:
a housing, an end of the housing comprising a protrusion;
a circuit layer placed on the protrusion;
at least one LED die placed on the protrusion and electrically connected to the circuit layer;
a light transmitting adhesive covering the circuit layer and the LED die;
a lamp shade connected to housing, the lamp shade and the housing cooperatively defined an accommodating space, the lamp shade comprising a plurality of ventilating holes; and
a light transmitting liquid fill within the accommodating space and the LED die sunk in the light transmitting liquid,
wherein the ventilating holes are configured to dissipate vapor generated by boiled light transmitting liquid to increase a heat dissipating speed and prevent the lamp shade from breaking by bearing over high vapor pressure, and the light transmitting liquid is refillable in reverse into the accommodating space through the ventilating holes, and
wherein the ventilating holes are higher than a level bare of the light transmitting liquid when the LED lamp in operation.

### Claim 2 (depends on 1)

The LED lamp in claim 1, wherein the heat-resistant temperature of the lamp shade is higher than 120 degrees Celsius.

### Claim 3 (depends on 1)

The LED lamp in claim 1, wherein an aperture of each ventilating hole is 5 millimeters.

### Claim 4 (depends on 2)

The LED lamp in claim 2, wherein the lamp shade is made of polycarbonate or glass.

### Claim 5 (depends on 1)

The LED lamp in claim 1, wherein a profile of the protrusion is substantially of triangle shape.

### Claim 6 (depends on 1)

The LED lamp in claim 1, wherein a profile of the protrusion is of arc-shape.

### Claim 7 (depends on 1)

The LED lamp in claim 1, further comprising a wavelength-converting matter disposed within the light transmitting adhesive.

### Claim 8 (depends on 1)

The LED lamp in claim 1, further comprising a sealing ring disposed at the position where the housing and the lamp shade connected.

### Claim 9 (depends on 1)

The LED lamp in claim 1, further comprising a plurality of wires electrically connected to the circuit layer.

### Claim 10 (depends on 1)

The LED lamp in claim 1, wherein the housing is made of ceramic powder by sintering.

### Claim 11 (depends on 1)

The LED lamp in claim 1, further comprising a controlling and driving module disposed within the housing and electrically connected to the circuit layer, the controlling and driving module comprises a plurality of electrical elements.

### Claim 12 (depends on 1)

The LED lamp in claim 1, further comprising a plurality of electrical elements placed on the protrusion and electrically connected to the circuit layer, the light-transmitting adhesive simultaneously covers the electrical elements.

### Claim 13 (depends on 9)

The LED lamp in claim 9, further comprises a conductive connector disposed on another side of the housing, the wires connected to the conductive connector and the circuit layer.
