Lamp shell device capable of heating and melting ice
Referring to fig. 3 to 5, an embodiment 1 of the lamp housing apparatus capable of heating and melting ice according to the present invention is suitable for being disposed in front of a light source 21 of a vehicle lamp 2. The vehicle lamp 2 has a lamp base 22 for the light source 21. The light source 21 projects light forwardly and defines an optical axis a1 extending forwardly and rearwardly.

The lamp envelope 3 is transparent in this embodiment 1, but may be transparent brown, orange or red in other embodiments of the invention. The lamp housing 3 includes a first face 31 and a second face 32 opposite to each other. The first surface 31 is concave and the second surface 32 is convex. In the embodiment 1, the first surface 31 and the second surface 32 are a part of a spherical surface, and are generally circular in the rear view, but in other embodiments of the present invention, the first surface 31 and the second surface 32 can also be a spherical surface, a paraboloid surface, or an approximation thereof. The optical axis a1 passes through the centers of the first surface 31 and the second surface 32 in the present embodiment, but not limited thereto.
The conductive film 4 can convert electrical energy into heat energy to heat the lamp housing 3, and in this embodiment 1, Indium Tin Oxide (ITO) is formed on the first surface 31 by electron beam evaporation and oxygen assisted plating, and the actual manner of evaporation will be described later. The size of the conductive film 4 is adapted to the size of the first surface 31, and the conductive film 4 is transparent in this embodiment 1, but in other embodiments of the present invention, the conductive film can be in a slightly colored light-transmitting state.
In this embodiment 1, the conductive film 4 has a thickness of 900nm, and has a main film portion 41 through which the light generated by the light source 21 can pass and through which the optical axis a1 passes, and an outer film portion 42 substantially in a ring shape and connected to the main film portion 41 in a surrounding manner. The outer film portion 42 is located at a position corresponding to the front and rear of the decorative portion of the lamp socket 22 surrounding the light source 21, has a substantially circular outer film edge 421, and is formed with a current blocking groove 422 penetrating from front to rear so that the lamp housing 3 contacts the protective layer 6.
The current blocking groove 422 has an extended groove segment 423 extending from the outer film edge 421 inward toward the optical axis a1, and a transverse groove segment 424 extending transversely to the extended groove segment 423. The extended groove segments 423 extend substantially up and down in this embodiment and are substantially T-shaped in cooperation with the substantially left and right extending transverse groove segments 424. The transverse groove section 424, the extending groove section 423 and the outer film edge 421 separate the conductive film 4 from an opposite surface 43 (see fig. 4) of the lamp housing 3 to form two conductive surface portions 431. Each conductive surface portion 431 is located between the extended groove section 423 and the cross groove section 424 and the outer film edge 421.
The electrode unit 5 is also formed on the conductive film 4 by electron beam evaporation, and the evaporation method will be described later.

The passivation layer 6 is transparent in this embodiment and is made of silicon dioxide (SiO)2) However, in other embodiments of the present invention, the protective layer 6 can also be transparent and the material can also be titanium dioxide (TiO)2)。
Method for making lamp shell device capable of heating and melting ice
Referring to fig. 6 to 8, the lamp housing device capable of generating heat and melting ice of this embodiment 1 can be manufactured by a method for manufacturing a lamp housing device capable of generating heat and melting ice as described below. The manufacturing method of the lamp housing device capable of heating and melting ice comprises a conductive film forming step S1, an electrode unit forming step S2 and a protective layer forming step S3.
In the conductive film forming step S1, the lamp housing 3, a metal mold base 71 for disposing the lamp housing 3, and a first mask 72 disposed on the first surface 31 of the lamp housing 3 are provided. The metal mold base 71 abuts against the second surface 32 (see fig. 4) of the lamp housing 3 to support the lamp housing 3. The first mask 72 has a T-shaped cross section and contacts the first surface 31, so that the portion of the first surface 31 shielded by the first mask is not evaporated.
Then, the pressure is 3X 10-5Introducing oxygen at a flow rate of 13sccm (standard cubic center per minute) under an ambient condition of torr and 80 ℃, and using indium tin oxide as a target with a plating rate of per second
Electron beam deposition under the conditions of (1). After the evaporation is completed, the first mask 72 is removed, so that the conductive film 4 having the current blocking grooves 422 and located on the first surface 31 of the lamp housing 3 can be formed.
Referring to fig. 6, 9 and 10, in the electrode unit forming step S2, a second mask 73 is first covered on the conductive film 4 and the current blocking groove 422. The size of the second mask 73 substantially matches the size of the conductive film 4, and two electrode slots 731 extending along the radial direction and left and right at an interval and in an arc shape are formed. The position and shape of each electrode groove 731 correspond to the position and shape of the respective electrode strip 51.
Then, the pressure is 3X 10-5torr and the temperature is 60 ℃, aluminum is taken as a target material, and the plating rate is per second
The second mask 73 is removed after the evaporation is completed, so as to form the electrode strips 51 on the conductive film 4, which are electrically connected to the conductive film 4, are opposite to each other, and respectively extend along the two opposite side arcs of the outer film edge 421.
Referring to fig. 6, 11 and 12, in the protective layer forming step S3, a mask unit 75 having two third masks 74 is provided, and the first end portions 511 of the electrode unit 5 are covered by the third masks 74 respectively, and then the pressure is 3 × 10-5In an environment of 80 ℃ and torr, silicon dioxide is used as a target material and the plating rate is per second
The mask unit 75 is removed after the evaporation is completed, so as to form a protective layer 6 covering the conductive film 4 and the connecting strip portion 513 and the second end portion 512 of each electrode strip 51, filling the current blocking groove 422 and partially covering the first surface 31 of the lamp housing 3.
Sheet resistance measurement
After the conductive film 4 was formed, the sheet resistance of the conductive film 4 was measured with a four-point probe tester, and the measured sheet resistance was recorded in table 1.
Penetration measurement
After the conductive film 4 is formed, the average transmittance of the lamp housing 3 and the conductive film 4 for light with a wavelength of 400nm to 700nm is measured by a spectrometer and recorded in table 1.
Temperature rise test
The electrode unit 5 was electrically connected to a power source of 19.2W, 0.64A, 30V to supply current to the conductive film 4, and the temperature of the portion of the example 1 corresponding to the main film portion 41 was recorded by passing through the thermal image chart shown in FIG. 13 every 5 minutes by a thermal imaging instrument, and the time vs. temperature was plotted as shown in FIG. 14.
EXAMPLES 2 to 4
Examples 2-4 are similar to example 1, except that: the thickness of the conductive film 4 in each embodiment is different from that in embodiment 1. The thickness of the conductive film 4 and the measured sheet resistance and average transmittance for each example are reported in table 1.
EXAMPLES 5 to 8
Examples 5-8 are similar to example 1, except that: in the conductive film forming step S1, the flow rate of the oxygen gas for the assist plating is different. The actual flux of oxygen used for plating assist in each example, as well as the measured sheet resistance and average penetration, are reported in Table 2. The sheet resistance versus thickness of the conductive films 4 of different thicknesses is plotted as shown in fig. 15.
EXAMPLE 9
Example 9 is similar to this example 1, except that: in the conductive film forming step S1, the use of the first mask 72 is omitted, and the conductive film 4 is made to have no current blocking groove 422. As can be seen from fig. 13 and 14, when the voltage is applied to the conductive film 4 of example 1, the temperature of the portion (substantially circled in fig. 13) corresponding to the main film portion 41 of example 1 can be raised from 0 ℃ to about 51.8 ℃ in 5 minutes, so that heat energy can be effectively provided to heat the lamp housing 3, the temperature of the lamp housing 3 can be rapidly raised, the ice and snow possibly accumulated or adhered to the second surface 32 of the lamp housing 3 can be melted, and the light form projected by the light source 21 can be prevented from being affected by the ice and snow. In addition, because the conductive film 4 is designed to be transparent, and has no opaque light-shielding part, the light shape projected by the light source 21 is not affected, so the lamp housing device capable of heating and melting ice can be used with the designed light source 21, and the light source 21 does not need to be redesigned or adjusted when in use, thereby having the advantage of reducing the production and design costs.
| TABLE 1 | Example 1 | Example 2 | Example 3 | Example 4 |
| Oxygen flow (sccm) | 13 | 13 | 13 | 13 |
| Film thickness (nm) | 900 | 600 | 680 | 1100 |
| Sheet resistance (omega/□) | 20 | 33 | 36 | 22 |
| Average penetration (%) | 71.8 | 77.7 | 79.7 | 64.5 |
As can be seen from fig. 15 and table 1, when the thickness of the conductive film 4 is 600nm to 680nm, the sheet resistance increases with the increase of the thickness, from about 33 Ω/□ to about 36 Ω/□, and when the thickness of the conductive film 4 reaches 900nm, the sheet resistance decreases greatly to about 20 Ω/□ and increases slightly with the increase of the thickness, for example, when the thickness of the conductive film 4 is 1100nm, the sheet resistance increases slightly to about 22 Ω/□. The average transmittance of light generally decreases with increasing film thickness.
Further, since the electric power formula of the element is P ═ IV, and the conductive film 4 is assumed to conform to ohm's law V ═ IR, and V ═ IR is substituted into the electric power formula, the electric power formula P ═ V can be obtained2and/R. That is, the lower the sheet resistance of the conductive film 4 is, the higher the electric power P value is, the more heat can be supplied to the lamp envelope 3 per unit time, and the ice and snow can be melted better. It can be seen from the above formula and the data in fig. 15 that when the thickness of the conductive film 4 is 900nm to 1100nm, the conductive film has better electric power and ice and snow melting effect.
As can be seen from table 2, generally, as the flow rate of oxygen flow increases, the conductive film has different oxygen defects due to the adjustment of oxygen flow, resulting in variations in sheet resistance and transmittance. Generally, at higher flow rates, the conductive film 4 will likely form fewer oxygen defects and thus increase the resistance, but particularly, although the sheet resistance increases when the flow rate is increased from 13sccm to 14sccm, the sheet resistance decreases again when the flow rate is further increased to 15 sccm. As can be seen from the experimental results in table 2, in the conductive film forming step S1, when the flux of oxygen for plating is 15sccm, the conductive film 4 has a lower resistance and a larger electric power, and the transmittance is also improved.
| TABLE 2 | Example 1 | Example 5 | Example 6 | Example 7 | Example 8 |
| Oxygen flow (sccm) | 13 | 14 | 15 | 16 | 17 |
| Film thickness (nm) | 900 | 900 | 900 | 900 | 900 |
| Sheet resistance (omega/□) | 20 | 35 | 21 | 60 | 85 |
| Average penetration (%) | 71.8 | 78.4 | 78.1 | 77.8 | 80.4 |
In addition, it can be found that when the film thickness is 900nm, the average transmittance is good for the light rays with different wavelengths of 400nm to 700nm, i.e. the visible light rays with each wavelength of 400nm to 700nm can be transmitted well. It can also be found that the larger the oxygen flow rate in the process, the higher the average transmittance of light.
Comparing the embodiment 1 with the embodiment 9, the conductive film 4 of the embodiment 1 can avoid the current moving in the conductive film 4 with the shortest path, that is, the current flowing only through the outer film portion 42 and bypassing the main film portion 41, because the current blocking groove 422 is formed. In detail, the conductive film 4 with the current blocking groove 422 can promote the current to flow through the main film portion 41, so that the main film portion 41 can generate heat more effectively, and the accumulated and attached ice and snow are intensively removed from the portion of the lamp housing 3 through which the light generated by the light source 21 passes, which is better in ice melting effect than the embodiment 9 without the current blocking groove 422.
In the embodiments of the present invention, each conductive film 4, each electrode unit 5 and each passivation layer 6 are formed by electron beam evaporation, which not only can improve the bonding between the structures, but also each conductive film 4 can better conduct heat to the lamp housing 3 because it is not necessary to use an adhesive with poor thermal conductivity to adhere to the corresponding lamp housing 3, thereby generating a better effect of removing ice and snow.
In the embodiments of the present invention, each electrode strip 51 of each electrode unit 5 is disposed on the corresponding outer film portion 42, and each outer film portion 42 is not overlapped with the light projected by the light source 21, so that the light shape generated by the light source 21 can be prevented from being affected.
In each embodiment of the present invention, each protection layer 6 can protect the corresponding conductive film 4 and the corresponding electrode unit 5, is made of a material of silicon dioxide or titanium dioxide, can also have an anti-reflection effect, and can be used to improve the transmittance of light, and even can be used to adjust or improve the transmittance of the lamp housing device capable of heating and melting ice of the present invention to a specific wavelength.
In summary, the lamp housing device capable of heating and melting ice of the invention has the following effects: the conductive film 4 capable of transmitting light is used for generating heat energy to melt ice and snow accumulated on the lamp housing 3, and the conductive film 4 can transmit light without a shading part and cannot influence the light shape of the matched light source 21, so that the lamp housing device capable of heating and melting ice can be directly matched with the existing light source 21 for use, the existing light source 21 does not need to be redesigned or adjusted, and the lamp housing device has the advantage of reducing the production and design cost.
The above description is only an embodiment of the present invention, and the scope of the claims of the present invention is not limited thereto, and the equivalent modifications made by the contents of the claims and the description of the present invention are also intended to be covered by the scope of the claims of the present invention.
